jevansio Posted November 18, 2006 Share Posted November 18, 2006 Just come back from the North East MR2 Dyno morning, I put the Sup on just to see what power she was putting out before I do any mods, these are the figures: Engine Power (measured) 350 bhp @ 5927 rpm Wheel Power (measured) 314 bhp @ 5927 rpm Power Losses (measured) 36 bhp @ 5927 rpm Engine Power (corrected) 365 bhp @ 5927 rpm Engine Torque (corrected) 335 lbs/ft @ 3516 rpm Pressure (standard) 968 mBar Temp (standard) 18 Degrees The car is a facelift (non-vvti) TT. Only power mods are: HKS Cone Filter Non descript exhaust (still fully catted) Boost up to 1 Bar Do these figures seem correct (esp 314 ATW), seems a bit high considering it's fairly standard and a UK only gets 326 ATFW. Was funny as we had 5 people in the boot & 2 in the back seats just to get traction on the rollers, it kept wheelspinning as soon as the 2nd turbo came online. Oh & I had to pull the traction control fuse to disable it as it was cutting in all the time. Jay Quote Link to comment Share on other sites More sharing options...

Jake Posted November 18, 2006 Share Posted November 18, 2006 Those figures seem about right for 1.0 bar. I wonder why it's boosting so high with both cats in place. Quote Link to comment Share on other sites More sharing options...

He has a HKS boost controller and FCD in place, didn't realise you could up the boost with the cats still in. Quote Link to comment Share on other sites More sharing options...
jevansio Posted November 18, 2006 Author Share Posted November 18, 2006 Where did you have it done? They're called MacDonalds, located in Lanchester near Durham, Jay Quote Link to comment Share on other sites More sharing options...
GeordieSteve Posted November 18, 2006 Share Posted November 18, 2006 How did they measure the losses? Oh and Durham.... must keep that in mind! Quote Link to comment Share on other sites More sharing options...

Yeah, it's the boost controller causing the raised boost, both CATs are coming out very shortly though Quote Link to comment Share on other sites More sharing options...

Ewen Posted November 18, 2006 Share Posted November 18, 2006 Ref BPU...Just so I understand, how far can the boost be raised (with FCD and BC) 'safely' on a JSpec without removing the cats ? Quote Link to comment Share on other sites More sharing options...

I've not had the Sup that long, but the boost controller receipt is years old, so I guess mine has been running 1 Bar for at least a couple of years, Jay Quote Link to comment Share on other sites More sharing options...

Is 1 Bar as far as people would risk ? Or is 1 Bar the max achievable without de-catting, even with an FCD and BC ? Quote Link to comment Share on other sites More sharing options...

jevansio Posted November 18, 2006 Author Share Posted November 18, 2006 Just in case...I didnt mean to imply your set-up was 'unsafe' Jay Hey no worries Ewen never thought you did , I was just inquisitive as to how much performance difference could safely be made without a de-cat. Is 1 Bar as far as people would risk ? Or is 1 Bar the max achievable without de-catting, even with an FCD and BC ? The reason I phrased my response in a 'mine has done this' type way, is that I don't really know the answer & didn't want to advise you 1 Bar is OK when it may not been. We need someone with more experience to answer this, Jay Quote Link to comment Share on other sites More sharing options...
Jake Posted November 18, 2006 Share Posted November 18, 2006 Define 'safe' Any boost increase above stock levels carries an element of risk. You'd probably be alright as long as the EGTs are safe. Are cooler plugs fitted? Have the AFRs been checked? On the dyno would have been a great time to check them. It would be more risky without the above.

Class One Posted November 18, 2006 Share Posted November 18, 2006 With both cats in place and running 1 bar boost, i would almost certainly say that your egt's will be running high. On J spec the cats cause the resritiction in the exhaust system and limit full boost to between 0.7 ~ 0.9 bar generally as a guide. Upping the boost, with that restriction in place won't be doing your engine much good. What other mods do you have in place? And as stated did the dyno print out show your afr's. And your 1st post stated an ambient temp of 18 deg c. Where did you have it done.....Barcelona? Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted November 18, 2006 Share Posted November 18, 2006 Have to say i find those figures a bit err optimistic for 1bar with both cats in place and just an induction kit, and i would take a look into AFR and EGT figures as i suspect they may be a little high for comfort, but if its been running like that for two years, i guess EGTs can't be that bad.

Other mods are, HKS Cone filter, non-name exhaust (looks like 3" pipework though), Iridium Plus (colder grade). No AFR's I'm afraid. Barcelona, I wish , it was up in Durham & it was bloody freezing outside , The boost controller came with the car & was set to 1 Bar, so I've just left it (always planned to get a full exhaust in the short term), so do you think I should turn it back to 0.8 bar until I get it decatted? Once i get it decatted am I OK on 1 bar though? J Quote Link to comment Share on other sites More sharing options...
silvershark44 Posted November 18, 2006 Share Posted November 18, 2006 i think they look about right if your car is in tip top condition. Ie good intercooler etc Quote Link to comment Share on other sites More sharing options...
