I see about the engine - good luck with that !
As for my turbo, it is a LOW mount, T25 Flange.
I belive it will run out of breath around 400WHP, but as FOR EGT's - i dont agree it wil be a problem.
The main problem with the T25 would most defently be excesive back pressure - not high EGT's.
The exesive back pressure, will limit the amount of boost i will be able to run before detonation etc - wich will limit my total power output potential.
High EGT temps are caused by:
1. Too lean mixture - wich will usualy cause detonation or melt something - way before you will actualy see high EGT's.
2. Too much RETARD will cause high EGT's because the fuel in the mixture will not have time to completly burn inside the cylinder, and will partly burn in the exhaust and rise the EGT temps.
3. Too Rich mixture, for a given timing point - again, like the above - will cause exess fuel to burn in the exhaust and rise the temps.
Soo.... if you try to fight high EGT's by adding fuel and RETARDING - you are actualy making things worse.
The right way to fight high EGT's, is to make sure the A/F ratio is rich but not too rich, and actualy ADVANCE timing, and not retard.
The thing is the ADVANCING is usualy limited by knock - so sometimes you can only try using some high octane fuel to be able to advance, or simply - turn down the boost.
Bottom line - this is what i have now - so will try to get the maximum of it - when i'll get tyred of that, or tyred of trying - i will go top mount with something decent !
