Whats up with my car? I have never seen above 12.6 MPG. Must be my driving habits; race, race and more racing.

 

Dont get me wrong, I can get 8-10mpg by hot rodding around, however, if I am cruising on the highway, I can easily see 20+ mpg. I also find that with the mods, I get slightly better mileage, doesnt take as much power and is more effeceint doing certain things like passing etc...of course, all out driving, my mileage will be worse. Obviously, I dont have a turbo for the mileage, but it does add up and get expensive over time- it does blow my and other peoples mind that I have 600hp and still decent mileage.

As for intercoolers, I think these are the EVO Supersports, I decided on upgraded intercoolers when changing out the boost hoses since the bumpers were off anyway.

 

Well nice so!

I decided on EVO IC's as well here when swiching the hoses, since the OEM were off all the time + I wanted to run safe with the new WG at WOT.

Let me know and show you dyno..I am very interested to see how better the IA Stage 4+ is doing compared with the old Stage 4.

Thanks!

 

I have a similar setup (no intercoolers, headers or boost hoses) and put down 500-516 RWHP on an 85 degree day with stock K24s and 91 octane flash. Dyno is attached. Notice the car makes ~500HP for about 2,000 RPM.

Interestingly, you can actually feel the eb and flow of HP as the wastegates adjust boost. for those 2,000 RPM as seen in the slight bump and dip in HP.

 

Ari,

do you have a graph with Hp/Torque/ rpms...the one that you have attached is just hp/mph

Also, do you have a dyno befor and after WG?

Last, K24 headers will give you 16 AWHP & 15 AWTQ more from 4,000 RPMS to the top

Thanks!
