I had my oversized TB from RPW installed today by my mechanic. I had 2 dyno runs before the install which came up with 114 and 117hp at the wheels. After the install i had 2 dyno runs which came up with 114 and 117hp at the wheels
This is not a typo
Where i did gain was in torque. I gained 15-20 Nm of torque in the mid-range which i can feel, most noticeable in 3rd gear accelerating past 3,500rpm. There is definatly more there. The problem he said with gaining more hoursepower through mods is that the car continues to run rich because it will not advance itself to produce more power. Something called the vortex sensor which i think is the MAS/MAF/WOTEVA sensor is to blame as it is set on the stock reading and won't advance itself much at all.
The only way around this is to get a piggyback ecu and they specialise in unichip which looks like the way i'll be going. They did a Proton GTi last week and got a 15kw increase at the wheels out of it. So with my current mods of extractors and full straight through exhaust, oversize TB and K&N pod, i should be looking at around the same gains, if not more.
