Moving forward - building a new doorslammer
I have been working on a new doorslammer for a while. It’s a light weight carbon fibre, 70 model Boss Mustang. My own design, my own blood, sweat and tears went into building the body with some helpers. And now we are in the process of building the chassis inside using Racetech Steel 4130 Chromoly. This is also my design which we drew up on Solidworks so if it fails its my fault and if its a success I will gladly take full credit.
We have a couple of races planned for the future.
Fuchs Australian Nationals - September 10-12 at Sydney Drag Way
The plan is to drag the statesman out and try a few ideas out that we may or may not have learnt from Mildura. Time will tell…
Calder Park Slamfest - November 20 at Calder Park Melbourne
If its ready we will take the 70 Boss, but I am not holding my breath. We will need to test it first, so you will most probably see the Stateman again.
More races coming…. with at least 2 more 1/8th mile events we would like to attend if they come to fruition. Those ones I hope we can debut the 70 Boss Mustang.
I will tease you with a couple of pictures sometime soon.
It’s been a while
Sorry for not writing for quite a while. I have a few excuses - I am a lazy bastard, my wife had a baby and been busy with work and play….
I guess I wasn’t really enthused to write about our performance for 2009. We junked three motors in 3 races. It was a very frustrating bad time for me and the team. In support of Top Doorslammer 1/8 mile efforts we slapped together an old engine and headed to Mildura for the first ever Slamfest in March 2010 with very low expectations due to our recent poor form.
Mildura was hot (40 degree) the flies were bad BUT the racing was great. We opted to go for a test run on Friday afternoon. The track looked fairly slick and that was demonstrated to me perfectly in the burnout where i lost complete control and nearly smacked both walls. Needless to say I was very embarassed and disappointed with myself. I didn’t make a run becuase I was a bit unsettled after that wild moment and I didn’t think it was a safe choice.
Saturday the main event. Due to the heat, racing was set back to late afternoon for the first run. Which saw Maurice Fabietti plough into the wall with huge force all but destroying his car which didn’t leave me or the other drivers I suspect with much confidence for our first run. As it turned out the Racetech Steel Statesman hooked up and launched harder then it has ever launched before. We had backed the power down as much as we could and ran a 4.24. This run was top qualifier and quickest for the round until Scott McLean picked us at the post.
The second round we made no changes and fronted up with a 4.20sec run. Taking out low et for that round and top qualifying. We were to run the secondest quickest winner from the second round in the final. That put us up against Mat Abel.
The final was run late in the night at about 11pm. The air had got better, but the track had cooled off. We miss judged the setup slightly after a poor reaction time we shot out with another personal best 60ft .99 but it was too little too late as Mat Abel had reacted quicker to the starting light and got away from me. At half track I got a little loose and backed off and coasted thru with a 4.4 something.
We were estatic about the weekend. The result, the track, the Mildura people/fans, my crew made it one of the best events we have ever attended. A big thanks to Victor Bray, Peter Kapiris, Maurice Fabietti and everyone else who helped get this event up and running including the mayor for supporting the event.
about Mildura Slamfest (our last race).
Exciting changes ahead…
The Broadbent / Blake team have gone through some significant changes since we last raced at the Australian Nationals September 08 at WSID which was ultimately rained out after two qualifying runs.
We have since changed our entire configuration, a move we think will see us have a lot quicker car to 330ft and a faster car overall. This should all be true if we can get the power to the ground and keep it straight.
Some changes we are making for this year’s competition include;
- Most significantly we have increased compression, this should give us the MPH we require to bring down our 2nd half times.
- We have also changed our diff ratio, this is a big change, but we think if we are smart we can get it to work.
- Our cams have been completely redesigned, to make better use of the unique 3 valve heads we use. Cams, being the brain of the engine, could bring us some serious horse power gains, if we have made the right move.
- We will now be using the same stroke as when we ran our personal best 6.20sec but with a smaller bore, the compression gain should make up for the cubic inch drop, power-wise , however we are at a further disadvantage due to our cubic inch to weight problem. (We are not too concerned about weight at this stage as we are also in the process of building a new car!!!)
- By the Nitro’s we should also have the programmable ignition timing device, that everyone else seems to be running. This will allow us to add and remove timing at different stages of a run as many times as we like.
- We will also attempt to run with a different suspension setup. This is to try and better handle the increase in raw horse power and the new diff ratio.
- In addition we have re-valved out shock absorbers.
There are more changes made but we just can’t reveal everything in case we hit something sweet.
With all these changes and more we are sure to have some dramas sorting it out but we feel we will be a whole lot faster once it all comes together. The engine will be working a lot harder, so maintenance is going to be something to keep our minds on. With the new cams and comp we think we should see many more RPM’s out of the engine.
At this stage we haven’t put our engine together, as we are still waiting for parts from USA, (due to arrive this week). We will have a mad scramble to put the engine together and find a fuel combination and predict a clutch combo to start with that should slide our Racetech Steel Aussie Bananas Top Doorslammer Statesman down the track safely.
Come see us race at the Karcher Nitro Champs, Presented By Shannons at WSID - Western Sydney International Dragway.
When - Friday 1st, Saturday, 2nd and Sunday 3rd May 2009
Who’s racing - Top Fuel, Top Doorslammer, Top Alcohol, Top Bike, Pro Stock, Pro Stock Motorcycle.
An AWESOME Result for Aussie Bananas and RaceTech Steel !!!!!
We raced in the 2008 Snap-On Nitro Champs last weekend on the 2nd & 3rd of May, in the Civenex Top Doorslammer category. All weekend we were the class of the field, with the exception of John Zappia in the Striker Monaro running yet another sub six.
Our new personal best of 6.208sec @224 mph saw us qualify in 2nd place, and we didn’t lose a race all weekend, defeating the world renowned and all round nice guy Victor Bray in his Castrol Chevy. And a hole shot win in the final, a 6.71sec beats a 6.67sec against Andrew Sutton.
1st run the car left poorly due to a mistake in the clutch set up, luckily it threw a blower belt off at before 60ft and coasted through to a 12.2sec pass against Joe Cutelli in the Corvette, who also had a problem on the line.
2nd run saw us against Joe once more, I made a mistake (short shifted 1st gear) and there wasn’t enough clutch to run hard, 6.400sec, excitedly for us it was the quickest pass for the night so far.
We sat out the final session for Friday night as it got cold and we didn’t want to risk damage to the car or engine and not be able to show for the elimination rounds on Saturday! Only 1 run was quicker than us on Friday evening being zap he pulled a 6.28sec.
The qualifying / seeding round was spectacular. An almost perfect run saw a new personal best of 6.208sec against Brett Gillespie in his BHE Chevy, who aborted after an uncontrollable wheelie. My run was quick off the start, nervously and against my will I short shifted again (only this time, not so bad!) i also had to muscle the wheel at around mid track.
In the Semi final against Victor I pulled a good light and ran through with a smooth 6.37sec beating Vic’s 6.80sec much to the huge crowds delight (the underdog phenomenon I reckon). This put me into the final against Sutton. After a 1 ½ hour delay in the staging lanes things were cooling off quickly. After the rest of the group 1 finals it was our turn. The clutch was set to “make or break”, with the dew setting in I swapped feet with .03 reaction, it immediately turned the tyres, and then shook violently (breaking my wheelie bars). A quick pedal and we were off again, it went like a rocket ship. Silly old me forgot to shift into top gear, (my mind was still on the start line) it wasn’t too bad though; she ran through with a huge amount of revs, but it was enough to nab us a hole shot win. 6.71sec beats a 6.67sec.
Thanks and congrats to my team for an awesome weekend!
And once again thanks to dad for having the faith and allowing me to pilot his pride and joy!!!!!
SUMMERNATIONALS - 15th & 16th February 2008
Our last outing in the car was in December 2007 at the USA vs AUS Top Fuel Challenge. We were very happy with the performance of the car at this event. We ran a PB 6.35sec at 226mph as well as 4 consistent runs. Also, thanks to ‘Servin it up’ the Aussie Motorbike Stunt Crew, I had an inboard camera with me which is very exciting footage I hope to have available on the site one day.
Over the Summer period as usual we have made quite a few upgrades and changes to the car and we are not sure what to expect for the Summernationals. It should be an exciting event with over 19 cars and an A and B class on race day.
Exciting news!! We have a new sponsor on board Racetech Steel - suppliers of a range of high specification metals including Chromoly, CDS Mild Steel and Aluminium. These products are available in a wide range of profiles: tube - round, square, rectangle and streamline plus sheet and plate. These specialist metal products are suitable for use in many critical applications as well as offering to engineers in many industries the opportunity to develop products requiring locally available high strength raw materials. They also stock a complimentary range of CDS and CDW tube in sizes specified in both ANDRA and CAMS rule books or hand books, for use in Roll over Protection Systems (ROPS / Roll cages) or chassis modifications in part or full tubular chassis race cars. Check it out!
Test & East Coast Nationals 2007
We were supposed to test the car on Sunday 19th August. It had rained all night but we went to the track anyway with an optimistic attitude. There was a meeting when we arrived in the scrutineering shed and the day was cancelled due to bad weather. Fortunately the event was postponed to the following weekend – Sunday 26th August.
The next Sunday after celebrating my mum’s 60th the night before we went to the track to try out our lock up clutch. The first run shook the tyres, 2nd run I shut off at half-track (as we planned) and 3rd shook the tyres again. Not the results we were looking for.
A big service was needed over the next three days to be ready for the East Coast Nationals. We took out the lock up clutch as we are not ready for it. My first qualifying run off the trailer was 6.70sec. This is a step in the right direction, the first time we have run a fresh clutch successfully down the quarter mile. The next run was 6.70sec again after we stepped the motor up a notch. I was blind on this run my computer / dash battery died in the burnout so I had no taco to read, plus no data to gather after the run. Gary Phillips ran a 6.01 beside me. It felt like I was so slow - he kept getting away. The final qualifying run I ran a 6.80sec late at night. The track was cold and the car got loose at the top end and I had to pedal. Probably would have run a 6.70sec again.
At the end of qualifying I was in 14th position, which put us in the bottom 8 field – the Den’s Cranes sponsored consolation class on Saturday. My first run was paired against Steve Packman. Steve ran a 6.48sec and I ran a 6.58sec, he got the win. A slight improvement but not what we hoped for. Hopefully next time we will run a little better.
After pulling the engine down we found a broken roller on a rocker. Probably lucky we didn’t have another run.
We hope to test the car again soon and improve on our performance. Thanks to Dad and Crew for all their hard work, and Deno Brijeski for sponsoring the B field! A special thanks to my sponsors Aussie Bananas, Turn 4, CNC Machinery Sales and Performance CNC.

Snap On Nitro Champs May 2007 - Top Doorslammer Chicago Shootout
The Snap-On Nitro Champs (4th and 5th May 2007) is not a championship round for Top Doorslammer. Instead WSID ran an invitational “Chicago Shootout” style round robin. Only 10 Sydney cars were invited. Friday saw 3 rounds of qualifying and Saturday was the top 8 get two runs, the first is for seeding and the second is for racing and the fastest two in the second round go to the final. This was a good opportunity for testing for all the teams, and to have a little fun at the same time.
The 1st run I was paired up against Sean Misfud in the Willy’s. I haven’t done many paired runs, but I have run the Wild Willy’s every time but once. I spun the tyres from the startline for about 3.5 seconds, I backed off and eased back on and ran through with a 7.474 sec at 217mph. For an untidy run I was surprised to see my best speed to date. We had an oil leak during the run, the breathers on the rocker covers rattled loose.
Our 2nd saw me pair up with Sean Misfud once again. For the first time ever the car did not misbehave and I managed to get to the finish line under full throttle light to light. It felt awesome. It turned out a 6.401 at 223mph, another new PB. I have dropped nearly .2 of a second off my previous best of 6.57. Again we had the same oil leak we needed to find a better solution. More silicone and a centre punch to keep the screws tight.
For the 3rd run we went out hoping to capitalise on our last run, not all cars were out for this qualifier so we were given a solo pass other wise im sure id have raced wild willy again! The car went super straight and I ran another good number 6.425 at 220mph. We had a lot of positive comments from spectators and friends on how well the car went. At the end of the third qualify round we were sitting fourth on the top doorslammer qualifying board. I was very pleased with this result - fourth out of ten cars.
Saturday, we prepared the car early and our first run was 4pm. I was paired up against Mark Belleri in his Camaro. I thought the cat left like a rocket ship it shook the tyres hard I shifted into second still shook and I shifted into 3rd and ran through to a 6.522 at 224mph. and another PB, fastest speed so far! I found lots of rubbish in the filter and it didn’t look promising. But I’d try and find and fix the problem. Unfortunately it had spun a bearing and nor did we have time or the parts to repair and we were OUT. We are spectators now.
Check out my runs on my media page: http://peterblake.rmwpublishing.net/media/
Congratulations to Mark Belleri for his stellar 6.13. It was an awesome run especially for a beginner, he has out shone himself as a driver. Also thanks again to my dedicated crew and especially my wife for doing her best even though she had an operation earlier that week.
Catch ya!

Summernationals February 16 & 17 2007
The Summernationals 21 Top Doorslammer entries and only eight qualify. This is my debut Championship event. This is just another test for us.
Friday qualifying and our first run was at 4.30pm. We made some suspension changes from last week. We had something that worked and didn’t want to change but we had some unusual wear and were forced to, (a repair was un feasible in the given week).
The first qualify run was good and the car went straightish it was only my second time in a pairing. I was beside Peter Lovering I left him on the line and ran through with a 6.81 losing a blower belt a 1000ft. I figured Lovering had problems on the start line, but when I pulled the chutes he wizzed passed at a million mph it scared the crap out of me, I wasn’t ready for that. He ran 6.80 it felt really good to be in front for an entire run. If we had been racing, I’d have won!!!
A quick turnaround for the second qualifier. The team worked quickly but when we went to start it there was a problem. A cylinder full of fuel was hydraulicing on the starter we rushed to get it started. Everything was fine, but on the start line how ever we experienced the same problem against the car wouldn’t start and we missed out on that run. That was really disappointing but we had to find the problem.
We did a leak down, nothing we decided that without pulling apart the engine (as we wouldn’t have time before the final qualifier) we would just make sure we back the engine off in the staging lanes before we start the car.
The final qualifier. The car started first go, 21 doorslammers ran single passes (top fuel wasn’t ready yet) my burnout was a bit better then recent and I quickly got into stage (I didn’t have to wait for any one). Trying to launch with as much heat as possible in the tyres it must have worked 1.03 60ft was the 2nd or 3rd best for the session (not my best 60 though) my best half track saw 170 something mph and 4.3 I also pedalled just after shifting to 2nd gear (it wriggled just a little) after about 15 or so runs/part runs I’m proud to say I saw the shift light come on for top gear for the first time ever. a fuel leak sprouted at around 1000ft just before I hit the chutes but I cruised through to a 6.57sec at 216mph. Finally a good run, I saw the shift light, it went straight. I actually felt pretty comfortable in this run. It is the fastest and quickest I have gone so far. The team were pumped with this result! Even one photographer said to Dad it was an awesome launch. Dad was chuffed.
Great to finally get the monkey off our back. the thing has potential. We are still 200lb over weight and with a one to two tenths pedal that’s almost a great run.
We didn’t end up making the top eight, we actually came 16th but we were really happy with result.
I want to thank my team for all there hard work and support (a special thanks to Gary & Peter), everything is starting to come together for us!!
I would also like to welcome our new sponsor TURN 4. And congratulations to our good friends Maz & Ben on their Wedding which I couldn’t make due to racing.
