IMO, not bad for the first time at the track in a new FI car, stock tires and 101 deg temp. I'm sure the times will go down.

the time is decent. trapping 5 mph more than NA cars is pretty sad..

Ozzy 370Z 07-25-2009 05:27 AM

the 60 ft time 1.674 is pretty impressive for a street car, But the MPH is a low which represents how much horsepower the engine is really making?? Was this a full pass??

You must have had a boost leak. That mph is horrible. You should be trapping in the mid to high 120's with 600rwhp. If you don't have a boost leak, I'd do a leak down test and compression test. When you pulled out of the meet the other night, your car was blowing a bit of white smoke. Not alot, but some.

I'm not an expert so I have to ask why?:confused:

Is it because we expect the power to come on late on a typical turbo car so the speed is made up toward the end of the run (assuming everything were working right)?

Well, here are 4 cars with considerably LESS POWER, all trapping higher, and lower et's. for a car that's claiming 600whp, seams way off. That car should be running
in the mid 11's with trap speeds 125mph + :tup:

Nissan GTR AWD (480bhp) 11.8 - 116.5mph
Corvette Z06 RWD (505bhp) 11.7 - 123.7mph
Porsche 911 Turbo AWD (480bhp) 11.7 - 121.2mph
2010 Ford Shelby Cobra RWD (540bhp) 12.4 - 118.0mph

You have to factor the G's weight with those other cars as well. Plus his car is an automatic with a non GTR transmission. I say go back at night when the temp is lower, warm the tires a little more and launch the piss out of it. Then report back.

I've seen the car while it was at GTM. It is a manual. So I figure some learning will be needed for better times. Also, after re-reading ... GTM tuned it to 600+ WHp at 12 psi. His thread in the other forum said he is now running at 9 psi, so the boost has apparently been turned down for more reliability.

At 9 psi, my HR is made 470WHp on the dyno, so I assume his VHR with external gates and bigger pipes should be a hair over 500WHp at the same pressure?

In any case, to be knocking on the doorsteps of the cars in minicobra1's list is still pretty impressive especially for the first time at the track in unfavorable conditions. And I'm fairly certain the manaufacturers / magazines use pro drivers to turn out those published times too.

Although possibly more risky, the EBC can always be turned up 2-3 more PSI to "seal the deal".:rolleyes:
