mean you have 33% more exhuast gas in the 3.1 over the 2.0. thats alot more back pressure.....
time will tell just saying because it worked in a smaller motor doesnt mean it will work in another.
besides go to a 427. thats 3.5L. thats DAM NEAR twice the exhaust gas as the little 2.0 evo.

Not really how it works. 2.0L 4-valve per cyl. reving to 9000rpm is the key thing you are missing. The easier way to look at it is just simple HP. Engine is an air pump, Xlb/min of airflow makes roughly Xhp no matter what the static displacement is. Bigger displacement engine doesn't equate exactly to more air thoughput. At 50lb/min of throughput per turbo, the .63's are at about 1.4 pressure ratio. Not bad for a street car but a race car doesn't need that quick of spool up.
That being said you are right that the .63's are on the small side. FSP was only sent them for back to back testing with .82's.
1.0 and 1.25 housings are available and interchangeable. |
