pump gas pete Posted August 17, 2006 Share Posted August 17, 2006 It is very easily done but I am confused. I asked what the drag racing record was for a 6 speed Supra in the UK. I like to have targets to aim at. Gaz kindly posted his time see below. Pete, When we drag race we only run race fuel for safety, and power. We make about the same power on Optimax though. We've ran 10.409 @ 145mph at Pod before on race fuel. Gaz. __________________ envyperformance.com The Performance Parts Company Well now I am confused because I thought that race fuel gave a fair degree of extra horsepower "safely". (100 extra in Usmans case) and yet it appears they make the same. Is the map backed right off? If the ENVY car makes the same power on Optimax as race fuel are we going to have to chase 10.4 ? I want to find out , still , who has the UK record on PUMP GAS (OPTIMAX) Any one help? Peter Link to comment Share on other sites More sharing options...
Alex Posted August 17, 2006 Share Posted August 17, 2006 The CRD 6-speed is the car to beat (well it was before it was tubbed). It ran a 9.x(4 I think). Anyway, you can run more power but it depends on the weather on the day really. Racetracks tend to get very hot, and so when you actually don't want the car to blow up you use the race fuel as a safety measure and not a power maker.

Guest Terry S Posted August 17, 2006 Share Posted August 17, 2006 Pete the race fuel should make a big difference mate, to either the amount of boost and/or the amount of timing you can run. If we are talking C16 or Klotz 118 then the difference could be massive. Link to comment Share on other sites More sharing options...
Bobbeh Posted August 17, 2006 Share Posted August 17, 2006 The CRD 6-speed is the car to beat (well it was before it was tubbed). It ran a 9.x(4 I think). Petes will be more akin to Envys than CRD's as its a street car, not a gutted drag car. Thats what I would aim at competing with anyway. Link to comment Share on other sites More sharing options...
Guest dee_rz Posted August 17, 2006 Share Posted August 17, 2006 aim for the fastest 6 speed privateer non funded/sponsered time that's probably low 11 at guess as i know i've seen a guy do a 11.0 i'm with terry here running a c16 or koltz type fuel with that octane a much higher power should be achieved wasn't it norris evo that dyno'd 760bhp @flywheel on pump gas and make something like 900 on c16 that was the difference i think something alone those lines he has more power now, not worth aiming for the big guns/sponsered/funded guys times just aim for privateer 6 speed with your power i'm sure aim if anything it's your for the taking Link to comment Share on other sites More sharing options...
Gaz Walker Posted August 17, 2006 Share Posted August 17, 2006 Oops sorry, just realised that came out wrong. When I said "we make the same power" - I meant to say the same power as you quote (in your sig) on Optimax. We make about 90hp more on C16 than we do on Optimax.

Don't just stick it in your BPU supra and expect +90bhp You may see a smal improvement over time as the stock ECU learns it can add more ignition advance but that's it, nothing like the gains from basing the map around the race fuel in the first place. -Ian Link to comment Share on other sites More sharing options...

pump gas pete Posted August 17, 2006 Author Share Posted August 17, 2006 OK ,,,, I am going to go with the Envy 10.4 but er......can I pass on the 145 'cos that IS a very good top end. My wide body (and my Wide body) may just take the edge off our top end. I am champing at the bit 'cos being the competitive soul I am I have real and imagined scores to settle. Please God don't let me blow it up.... Please God don't let me blow it up.... Please God don't let me blow it up...... Bobbeh is quite right .... I want to drive to the track , on pump gas ,race and drive home. The rear seats ARE removed but have been replaced by 10" subs which Darren assures me is the only way to listen to Leonard Cohen. One other race concession we will have to make is rear wheels. We will be taking a set up with us 'cos I have no wish to wear out my road tyres and the race ones have a road life of 3kmiles. We would like to be the quickest/fastest private Supra. 6 weeks .............it seems like a lifetime. Link to comment Share on other sites More sharing options...

mkirby Posted August 17, 2006 Share Posted August 17, 2006 You see i'm not too bad with my dodgy datson lol the fastest 300zx in this country so far is only 12.7 which should be pretty easy to beat with my old set never mind my new setup the only thing which worries me is if i do get her into the low 11's or high 10's will i get the bug and go away from having a super fast road car and start getting silly and stripping it out etc Mike Link to comment Share on other sites More sharing options...

Bobbeh Posted August 17, 2006 Share Posted August 17, 2006 Pete, I'd pick up a set of BFGoodrich g-Force T/A Drag Radials to try, then if you really get serious try some 15 inch wheels with some slick/radial at the back. Link to comment Share on other sites More sharing options...
pump gas pete Posted August 17, 2006 Author Share Posted August 17, 2006 No No you don't understand Lee T ..I AM A WIDE BODY as well. (Middle Age Spread) Bobbeh, on our 12.26 run an eternity ago it ran a bye. Darren and others could hear the wheels spinning up in 1st....2nd....3rd....4th....5th...... We had definite issues with wheelspin. We hope to have cured it with a couple of changes in downforce. Our road tyres are only 315s but........ In our stock to be brought out when ness. we have a lightweight set of wheels , made for us Stateside , which at the time they were made , were the widest they had made for a Supra.....anywhere. We can now fit our 345 BF Goodrich Drag radials UNDER the arches. We await developments on the wheelspin front now!!! I have just nipped upstairs at the factory to look at them.....yummy. Gaz.....to put a date on coming out is to invite stress and dissapointment. When we are ready you will be amongst the first to know.

MONKEYmark Posted August 18, 2006 Share Posted August 18, 2006 be good to see you set your own time.good to see competition.what wheels you go with.are they 15" drag wheels? on supra forums they seem to go with 15” Bogarts with 325/50/15 MT E.T.

Steve Sherwood Posted August 20, 2006 Share Posted August 20, 2006 Our car made 685 rear hub hp on BP ultimate, this was a conserative tune for road fuel. It made 849.6 on race fuel with 20 degrees more advance, we had a significant boost leak on the VW manifold so should make more. Link to comment Share on other sites More sharing options...

pump gas pete Posted August 20, 2006 Author Share Posted August 20, 2006 I am still trying to get out of the door....customers e-mails this time..... Will do spec during as best as I know it......which won't help much... lets see Veilside.....1200cc injectors...fuel pumps and stuff...4 row.....fans electric....272s....ported head.....billet crank.....crower rods ......pistons of some kind ....hks?.....a 76? turbo......what else is there to say.... As you can see I don't take a great deal of interest in what goes into the car.....Darren just gives me bills and headaches.....its got "stuff". I am sitting here looking at the screen and really there is not a lot to a car engine is there? Steves car sounds really good......but tempting though it is to run race fuel.......not this year.....lets see what can be achieved on pump.
