yes that is very much true. after about 5000rpm, my car doesnt make any extra power. thats just cause of the small turbo our cars have. if u want to fix this *problem* get a bigger turbo that will sustain 2.2L induction at very high rev's.cause i noticed after about 5k...the power isnt as much???
ahh cool. i didnt know that. thx for the info mateducktape, that isnt absolutely true.. yes a bigger turbo will help the car produce more power up high, but due to the nature of these engines (long stroke etc) they are just not meant to rev..
