neo1 Posted June 6, 2005 Share Posted June 6, 2005 I know this is a huge area of GREY because all car tuning is very unique... and all our Supras are set up in different ways..... However, at a rough guess what BHP would a supra MK 4 be if it can run a 10.68 standing Qurater. It hasn't been on a RR yet. Link to comment Share on other sites More sharing options...
colsoop Posted June 6, 2005 Share Posted June 6, 2005 What was the terminal speed that is a better indicator of power Link to comment Share on other sites More sharing options...
lust2luv Posted June 6, 2005 Share Posted June 6, 2005 Quarter mile times depend largely on tyres, suspension set-up, launch method, amount of grip, etc. As colsoop says, terminal speed is a much better indicator of power. For a 10.68 I imagine you'd be talking roughly 600HP+ at the crank at the very least. Link to comment Share on other sites More sharing options...
neo1 Posted June 6, 2005 Author Share Posted June 6, 2005 127 mph, Dunlop S 9000's, Not heated up and not on launch pad glue.... Getting relative spin up in first and some in second as the suspension needs the compression / rebound fine tuning. Ran 4 passes, this was the best time. Worst i did was a 12.3 but that was spinning up in third gear as im still a little trigger happy Link to comment Share on other sites More sharing options...

Bobbeh Posted June 6, 2005 Share Posted June 6, 2005 Much more than 600, I'd say closer to 800 for a full weight car. You have to think: a McLaren F1 runs 640bhp and does 11.0 sec 1/4 mile times, so you can work the rest out. Link to comment Share on other sites More sharing options...
Gaz Walker Posted June 6, 2005 Share Posted June 6, 2005 127mph - I guess between 750-850hp. Thats a great time - whats been done to the car... What strip was it at? Gaz. Link to comment Share on other sites More sharing options...
Ian C Posted June 6, 2005 Share Posted June 6, 2005 Er, surely these power outputs are a little high...? Terry got a terminal speed of about 125mph at the brunters bash and he's got around 550bhp... I would have though 800 would get you up in the high 140mph mark? -Ian Link to comment Share on other sites More sharing options...
normore1 Posted June 6, 2005 Share Posted June 6, 2005 Simple formulas for ET and Speed HP calculation The formula is: hp = weight / (ET / 5.825)3 The formula is: hp = weight * (speed / 234)3 Using the ET method for 10.68 sec, I come up with 600 horsepower Using the Speed method for 127 mph, I come up with 592 horsepower Link to comment Share on other sites More sharing options...
normore1 Posted June 6, 2005 Share Posted June 6, 2005 BTW, these numbers are at the rear wheels using 3700 pound gross weight (car, petrol and driver). Crank would be about 700 HP derek Link to comment Share on other sites More sharing options...
Digsy Posted June 6, 2005 Share Posted June 6, 2005 Well I tried to work this out from first principles and I'm coming up with some very low numbers. Not sure where I might be going wrong (spreadsheet attached).Power spreadsheet.zip Link to comment Share on other sites More sharing options...
neo1 Posted June 6, 2005 Author Share Posted June 6, 2005 I have a lightweight bonnet and cone, so not a huge weight loss really. I think 800 way off the radar....(i wish) I was told a possible 600, i think in reality myself it's more like a solid 550 on high boost, does this make any sense to anyone However, the tuning is a COMPLETE Enigma, it still uses sequential turbos which is very odd given the times it is running.

neo1 Posted June 6, 2005 Author Share Posted June 6, 2005 I knew you would laugh, a couple of people that i know did as well It just doesnt make sense.... I drive it and i don't see how its possible. The only way i think it could be doing this is if engine itself has had mucho internal work done. I was told the turbos have had staged internal re-work and ceramics replaced but still Its all talk and guess work that friends in the know have given me, i dare not take it apart as it works and works well. Photos are pointless, it just looks normal other than the HKS FMIC induction and injectors, no bling anywhere to be seen, and stock manifolds and throttle body. Hmm, dont want to be drilled into the ground by everyone because its not a single conversion so will book it onto a RR and post what it comes up with.

neo1 Posted June 6, 2005 Author Share Posted June 6, 2005 Please dont slag me on this one.... i will get it on a dyno. I dont see how its possible either. Link to comment Share on other sites More sharing options...
Gaz Walker Posted June 6, 2005 Share Posted June 6, 2005 We aren't laughing but I'm sure some people will find it hard to believe. They best time anyone here has run on stock tubbies is 11.9 - that was an auto with an uprated stall and a good drag racing driver. With a proper strip, tyres, line lock, burnout etc you could get low 11, maybe even a ten (they can in the states) it just sounds hard to believe. Then again it might not be stock turbo's at all. Have you got the slip? Which track was it at? Gaz. Link to comment Share on other sites More sharing options...
Bobbeh Posted June 6, 2005 Share Posted June 6, 2005 No ones slagging you. 10.6 is unbelievable on stock turbos as it usually takes cars on Drag radials and pushing ~ 800-900 bhp to achieve those times, usually with huge single turbos. So either there has been a mistake somewhere like with the timing or you have had massive engine upgrades. 12.1 is much more realistic. 10.6 is world record breaking.

neo1 Posted June 6, 2005 Author Share Posted June 6, 2005 Ok i am going with a time mistake here, it just does not seem possible at all. But it did repeatedly run high 11's. I am taking it to pod in a couple of weeks and im sure there times are spot on. The reason i posted this is because i couldnt make any sense of the time in the first place, i know you need a big single and all the rest to get even close to that sort of time. Either that or a twin single HKS type setup. A muck up must have been made. Link to comment Share on other sites More sharing options...
Bobbeh Posted June 6, 2005 Share Posted June 6, 2005 Maybe you have hybrids? They look the same but you could be pushing out 500~ bhp. Do you have a FMIC etc? You'd certainly know if you had HKS twins, as they'd be slapped over the 2 big shiney turbos looks like this pig fly's faster lol I seriously doubt it Link to comment Share on other sites More sharing options...
