Tom

Not stock, I have the following add on's:
Watson Headers - No Cats (yet)
Open Lid w/ K&N Filter
Coplon Duct
Marc Haibeck Chip w/ Calibration for the headers
Flowmaster #17115 Cat Back Exhaust
Hurst Short Throw Shifter

The 12.532 run was with a launch at about 3500 RPM's, may have been a little higher too, I don't really watch the RPM's as I am trying for good lights. RT's that day (first of the season) were .121, .113 and .116. I usually run about 28 to 30 lbs of air in the front tires, but didn't let any air out as I wasn't really looking for good lights here (just a T&T). I have the Goodyear GS-D3's and I heat them up with a rolling burnout (no water) and 25-26 lbs of air. The car hooked real well with a 60 ft time of 1.928, the best 60' I've had to date.
Ryan used NHRA correction factors and this run at sea level calced to a 12.12 @ 116.60

No problem on the reply Tom. No porting, and probably won't. I'm pretty happy with the way the car runs now and never have been one that longs for more and more.

I bracket raced a '70 Camaro for 8 years and watched everyone around me go faster and faster and spend more and more money. All it got them was a car that would eat up their bank accounts. The funny thing was I whipped their *** everytime I pulled to the line with them. They'd come over and we'd talk about how much faster they were and I'd put the money (from the wins) in the bank and they'd just spend more to go even faster and break more stuff.

Well all I can say is that your skill as a driver shows, and the car ain't too shabby either!

Oh, and I agree 100% with what you wrote in the post above! Almost any sports car is a money pit, how big of a pit just depends upon how fast & quick ya wanna go! I remember this line from somewhere: "Speed secrets, besides military secrets, are the most fleeting secrets in all the world!".....I think it was in a car mag...I think?

I agree about trying to go tooo far power wise , with one exception the porting of the inj and plenum . its a no brainer along with the headers and really completes the car. going any farther gets costly .. i can hardly wait to see what headers do on the callaway . very nice 60ft on street tires by the by . i'll bet you drive the youngsters nuts having their modded cars being slower than you ,these cars still hold their own after all these years.

i'm with ya, considering he hasn't opened up the lump at all...can't say he isn't getting the most out of it. i'm impressed & believe me that dosen't come easily.

Thanks for all the compliments guys. I'm pretty happy with the results.

I talked with Marc the other day and as far as the clutch goes for our cars that are under 500 HP, he has used the Duralast Clutch from Autozone, Part No. NU0084, $258. He has had good luck with it and that's good enough for me.

just a thought . corey put a ceramic disc in when we did the fidanza and boy does she grab well . even after 50+ runs at the strip .
