Paul372 Posted October 1, 2008 Share Posted October 1, 2008 theres alot of pipe work there surely a single turbo setup would be much better Quote Link to comment Share on other sites More sharing options...

JamieP Posted October 1, 2008 Share Posted October 1, 2008 Why run it so lean? What boost are you up to now? and what are the EGT's on full throttle top gear? Quote Link to comment Share on other sites More sharing options...
Guest Xabin Posted October 1, 2008 Share Posted October 1, 2008 I must runs so lean becuse of the turbos working at there beast.. This turbos are not like Garret for exampel when you should run in 12-12,5 at full. These turbos har so great flow so thats way i can run so lean and EGT is 850c(1562F) and the boost now are 1bar (14,5psi) my taget in the boost are 2 bar (29psi) or bigger turbos i have lookt att KX600 turbos.. Littel spec on the IRX 450 turbo inducer diameter 58,5 mm backwheel diameter 82,0 mm Turbinewheel Exducer diameter 58,0 mm wastegate hole 33,0 mm Quote Link to comment Share on other sites More sharing options...
Wez Posted October 1, 2008 Share Posted October 1, 2008 Why do different turbos allow you to run lean, all they do is produce a volume of air, this needs to be mixed with fuel to generate power. Its the combustion process that generates the EGT and dictates AFR, the turbo are just a means of delivering air. Please provide more info as I am a little confused.

Wez Posted October 1, 2008 Share Posted October 1, 2008 What fuel are you using? Quote Link to comment Share on other sites More sharing options...
Guest Xabin Posted October 2, 2008 Share Posted October 2, 2008 The differens betwen the turbos are how good thay move away the exhaust and how great flow the have on the EX side thats what i have been told from them ho have built the turbos.. I hope thats anwser your question I´am runnig on 98octane Quote Link to comment Share on other sites More sharing options...
bigbloodyturbo Posted October 2, 2008 Share Posted October 2, 2008 will watch this one just out of interest but i cant help but think its going to end with a broken supra. 13.8:1 at wot in a turbo motor is pretty bad. Even if your turbos are the most efficient turbo's in the world it doesn't change the fact that the combustion temperatures are going to be very very high. Whether you get 13.8:1 from a turbo or from nitrous its still 13.8:1, thats more than most people run normally aspirated never mind turbo. good luck though.
