Having issues where the car is losing power over 7500rpm.
Dyno says up on power low and mid range and drops off after 7500rpm
Possible loss of 10-20bhp over same spec cars
details
ep3 UK spec K20A2
202bhp on the dyno
Standard ECU
Tegiwa Intake
Tegiwa 100cel cat
Tegiwa 3" exhaust
190-200psi Compression on all pots.
On track seeing temperatures of 100-115 peak degrees Celsius.
and noticeable loss in power straight line compared to other Series cars. maybe 5-10mph down on the straights.
Anyone think of any issues and things to check, change etc.
Trackday videos showing a noticeable change between a couple of days in top speed on the same track. Cant recall changing anything other than fresh plugs same make.
