Depends where you make the 300.

You mean in the powerband where it peaks? Are certain RPMS more dangerous or something??

300 hp a peak rpm is a lot less hazardous than 300 hp at 4000rpm.

I see exactly what you are saying and thanks for that info man, I can relay this info to whoever tunes it so it's a little more conservative

Boosted at 8.6 psi with AVO 1.5 Kit for the last 5 years/40k. Mine was one of the first AVO kits in the country. The car is still producing precisely what it did in 2013. 270hp + 212tq. NOT ONE ISSUE!

Drift Office - Best place in the country to get your FA motor tuned. Nuff said.

Hbp pulley?

Matt@Cosworth · 04-23-2020, 02:21 PM

one thing to mention that hasn't been so far is exhaust back pressure

the stock system is quite restrictive and going up to a minimum of 2.5" if not 2.75 to 3" really pays dividends and will help with the motor life as less back pressure means its more resistant to knock and less knock events = a happier motor

People should comment whether they track the car or not. I have no doubts in my mind that you can keep a low power FI setup (sub 300 whp) alive for maybe the life of the car *if* the car is only a street car. That same setup might only last a few track days with a fast driver.
