Thorin Posted May 11, 2008 Share Posted May 11, 2008 EGT's nice and high then. I think those figures are a little inflated though. Quote Link to comment Share on other sites More sharing options...
tooquicktostop Posted May 11, 2008 Share Posted May 11, 2008 Nice figure What EGT's did you see on the car at that boost ?? Edit, too late again ! Quote Link to comment Share on other sites More sharing options...
Dr_Doom Posted May 11, 2008 Share Posted May 11, 2008 (edited) That can't be good for your turbo's surely?.. I thought increased boost with the first cat in = lots of heat = turbo failure! It's happened to lots of people on here. The turbo's just break to bits because of the intense heat!.. I'd get the first cat removed asap and fit a restrictor ring Edit - have a look here http://www.mkivsupra.net/vbb/showthread.php?t=139380 Edited May 11, 2008 by Dr_Doom (see edit history) Quote Link to comment Share on other sites More sharing options...

tooquicktostop Posted May 11, 2008 Share Posted May 11, 2008 Norm Power 418.5 bhp Engine Output 409 bhp Wheel output 242 bhp Drag output 167 bhp Max power @ 174 mph Air Temp 25 Air Pressure 1009 Thats a big drop between engine and wheel output, it does not look right to me, also what about EGT's ?? If wheel BHP was 242BHP I would have expected about 310 ish engine BHP Quote Link to comment Share on other sites More sharing options...
Guest bazza. Posted May 11, 2008 Share Posted May 11, 2008 Your going to have to help me out here whats the EGT:rolleyes: Are the rollers at Interpro normal on the high side then? Quote Link to comment Share on other sites More sharing options...
Jake Posted May 11, 2008 Share Posted May 11, 2008 Norm Power 418.5 bhp Wheel output 242 bhp That's the most ludicrous thing I've read on here for quite some time! 42% drive train losses? Yeah right Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted May 11, 2008 Share Posted May 11, 2008 EGT = exhaust gas temperature, too high means big probs! Thats a massive loss between engine and gearbox. If it was 309 crank and 242 wheel thats approaching normal loss. Is it auto or manual? Quote Link to comment Share on other sites More sharing options...

Swampy442 Posted May 11, 2008 Share Posted May 11, 2008 My auto (soarer) lost 60 horse between crank and wheels on an estimated crank output of 385, thats some idea. Quote Link to comment Share on other sites More sharing options...
tooquicktostop Posted May 11, 2008 Share Posted May 11, 2008 What did the garage say about the readings ??I am genuinely interested as they should have flagged it up as an error Also did they recommend you run over 1.1 bar with first cat in ?

Scott Posted May 11, 2008 Share Posted May 11, 2008 Did you pay extra for this run? I would be asking some questions if i were you. Quote Link to comment Share on other sites More sharing options...

JamieP Posted May 11, 2008 Share Posted May 11, 2008 Lol 42% drive train loss, not the first time ive seen this from interpro, i think it was Jake that pointed it out last time aswell. good for the pub talk:D Quote Link to comment Share on other sites More sharing options...
Homer Posted May 11, 2008 Share Posted May 11, 2008 The dyno records RW torque, from which it calculates rwhp (so the figure of 242rwhp can is the 'true' reading from the dyno). At the most optimistic the auto box loses 25% of the engine output, so a realistic flywheel figure would be between 305 and 310bhp. This is a little low for 1.15bar, but with the 1st cat in place it's going to be a huge restriction on the system. It's really unwise to run more than 0.9 car with the 1st cat in place due to EGT issues. The dyno run is still worth it as you have your rwhp figure (the one we all prefer to use here when doing comparisons), just ignore the flywheel one as they're almost impossible to calculate with auto's on a wheel/hub driven dyno. with 1.2bar you should be seeing about 330rwhp on the auto, 350rwhp on the 6spd. So clearly some more work needed to get your hp where is should be for the boost level. Quote Link to comment Share on other sites More sharing options...
Guest bazza. Posted May 11, 2008 Share Posted May 11, 2008 So why would the car be holding back so much do you think I know if i remove the Cat it would help but not that much. As i have the HKS FMIC and Super dagger and Filter:( Quote Link to comment Share on other sites More sharing options...
Homer Posted May 11, 2008 Share Posted May 11, 2008 The cat is the likely cause here. You must remove it with the boost level you are using. Do you have a restrictor ring fitted? What 2nd cat/decat do you have? Cat back exhaust system? Quote Link to comment Share on other sites More sharing options...
tooquicktostop Posted May 11, 2008 Share Posted May 11, 2008 So why would the car be holding back so much do you think I know if i remove the Cat it would help but not that much. As i have the HKS FMIC and Super dagger and Filter:( Removing the first CAT and fitting a restrictor ring would help a lot actually, the first CAT is very restrictive Also an uprated fuel pump, new fuel filter.... Infact look here BPU and all will be explained Quote Link to comment Share on other sites More sharing options...
Guest bazza. Posted May 11, 2008 Share Posted May 11, 2008 The 2nd decat is a HKS pipe it was on when i got the car I normal only run .95 bar boost it was only for the run it was turned up Quote Link to comment Share on other sites More sharing options...

jaymdee Posted May 11, 2008 Share Posted May 11, 2008 As a guide, my Auto TT running 1.05Bar made 323 rwhp at Surrey RR last year. Surrey don't apply a conversion to Auto's as it's unreliable. Quote Link to comment Share on other sites More sharing options...
jaymdee Posted May 11, 2008 Share Posted May 11, 2008 Oh, and my MR2 Turbo made 225 RWHP on Saturday at stock boost (0.8Bar) - Charlie said it was a very healthy engine I would get that first CAT out and take it fom there as I think a stock TT should be pushing 265 at the wheels.

Scott Posted May 11, 2008 Share Posted May 11, 2008 Oh, and my MR2 Turbo made 225 RWHP on Saturday at stock boost (0.8Bar) Not bad, they only had 200 out of the factory. Either thats an extremely dodgy dyno or your mate is running more than stock boost, or other choice mods. I'm guessing that its a rev 3? FWHP is 245 stock and a rev 1/2 is 220 stock Quote Link to comment Share on other sites More sharing options...
