419.7 Bhp / 420.8 trq external temp was ~21 'C



my friends car running the high boost....and different cams....is making so much less power than mine after 5500 Rpm...that is why on the street my car is faster...although when i drive his car it feels like it pulls harder...


anyways bosshog...how much millage have you put on your car with this setup at 1.7bar of boost? how do you drive..are you a moderate driver or beat hard on the car?

please let me know ... i am thinking of adding an FP Green...next and raise the boost to ~1.7...

and is your fuel equivilant to 97 oct (relative to us gas or europian)

thanks for the answers....cant wait to take my car to the track next week...

back to back testing i did and i saw 12-13whp increase on my car on the same Dyno Dynamics with much less bolt ons than other guys and 22psi spike and then i had a leak also from my greddy type-rs bov, which i changed it to the stock unit again until i install the tial unit i got...

here is my before and after dyno sheets with the cams. The final result was with the crappy megan header which was leaking and my stock turbo is maxed out as you can see.

Im sure most, if not all those results came from the alky, not the cams, Again not a good comparison.
Why does nobody have a straight before and after Cosi cam install, without leaks or the addition of other mods...

The difference between these two dynoruns is the cossie cams!!!! Yes i had the leaking bov but the leak was there for both dynoruns, meaning before the cam install and after... Its 13whp increase on the Dyno Dynamics at 22psi spike, dropping almost immediately to 21psi and tapering to around 17psi to the redline...

S1's are made for small turbo's..

Cosworth's and S2's are made for bigger turbos..

If you need a larger cam, then consider Cosworth or S2's..

It's like sayin; "I can't decide between HKS 272's or JUN 272's? I mean their the same size right?"
