SFR 60-1 twin turbo,476WHP stock motor
The Z car club had a dyno day today so I figured I would put the Fearlady Z back on the dyno to see what it could do on a cool day.To date, our test mule 350Z has our SFR twin-turbo system and a dual 3" HKS exhaust.I also plumbed in a Profec E-01 for boost control. No other mods at this time.At 10.4 psi we clicked off 476 horsepower at the wheels on 91 octane fuel.This was done on a stock motor,stock cams, heads, spark plugs, clutch, stock everything.Not too shabby.The next thing we are going to do is reflash the ECU for higher rpms, run some Iridium plugs and raise the boost to 11.5 psi and see if we can get past the 500WHP.After that we are going to test our new twin plenum intake manifold and some cams and see how much more we can get out of a stock block and heads

No return fuel system.13 to 1 through the tailpipe. I need to add a little more fuel at high rpms. Unfortunately, it was a dyno day and not a tuning session, so hopefully I can get on the dyno again real soon and do some tweaks to the fuel curve.

We are not done yet.Hopefully we will see over 500WHP with some tuning of the air/fuel mixtures and some decent spark plugs.The goal is 500+WHP with just a turbo kit and exhaust
No cams, no pulleys, no plenums, no breaking into the motor and no gadgets or gizmos.
Oh what a difference a year or two makes. This motor(and it's tuning) sure is evolving. Great numbers Tim. I look forward to more of your products coming out.
