POTENTIAL OF S15 TURBO???? CONFUSE!!??


Tiger look S15...


Shorten inter cooler pipe.


Power compare with just boost up.

Set same boost.


Today this car turn up for tune.......................looks aggressive(*=*)'


Anyway check this car out first...... got lots of stuff (external, exmani, modify inter cooler, HKS twin power, etc,etc) ...however the owner of this car say.... engine is standard, only camshaft and head gasket. idle is "dou dou dou"....what sort of camshaft is that???


Normally S15 has six speed gear box, but this car has 5speed.....So 4th gear is 1:1 3.6??.........It's too wide isn't it??? So this guy changed diff to a S15type-S diff...4th gear became..4.083 1:1...sounds good!!!...........
Let's do it.... ???strange!this car doesn't make knock much like the other's !!!???
Result..........over 237kw at wheel???........standard turbo???.....well let's compare with
S15 boost up, both of them are the same boost.........looks bit slow response, may be form camshaft??? and under 4000rev, just boost up is better poer and response!! ...but high rev....Because of .....what???
What do you think??? I wanna answer(>_<)'
