Tom, it's Beach Bend in Bowling Green, KY. The CF Cruise In has the track for the day. I'm guessing that I'm maybe a second behind you. Big Fish38857.1601388889

Vette(s): 1975 C3 Red, T-Tops, Black Interior. All I need is time and money! Getting there!

Excellent!  And a lot of fun!   With brakes working right and a bit more torque you'll see that 12.    Factory specs on mine said 16.5  But in present trim I'm guessing 14.8 or 14.9.  One of these days it will be fun to find out.

I don't remember what engine/mods you are running.  Can you give us a quick rundown?

You may want to invest in a line lock for those  neck snapping Launches.

I can`t wait to get mine to the track after all the new work i put into her.

Just have to keep driving it to break her in.

Vette(s): 1972 conv., sunfire yellow, blk interior, blk vinyl and convertible top. Off frame restoration with American Speed 383 stroker engine producing 500hp plus a 200hp NOS system. MSD ignition. Hooker super competition headers with chambered exhaust.

How many miles should you have on a new engine before you take it to the strip? My car has almost 1800 miles on it now.

Here's what American Speed has to say about their engines but I can't afford to take any chances.

Every engine from 275 hp to 700 hp is dyno tested and tuned to insure power levels, reliability, and we break the engine in under a controlled environment. Engines are thoroughly checked to dyno then disassembled and checked again before delivery.

I have seen opinons on both sides of the spectrum, break it in gradually and gently, or run it hard like its intended to be right from the start. Me personally, I ran my engine for about 50 miles until I started to beat on it. I am very hard on this motor, because I can be, I am not afraid to break it, since I can rebuild it myself cheaply. As long as the tune is right and detonation is controlled and it gets plenty of oil and cooling,it would be hard to hurt a properly built motor. rearn2go72- as long as you feel comfortable that the motor has all these requirements and your nitrous is safely set so that your motor will not detonate its self to death, you should be fine to go to the track.

The NOS is set to kick in at 2600 RPM and kick out at 6000. I have never turned the nitrous on but the more I drive the car, the more I'm tempted. It presently has the 200hp jets but I think I'll have it changed to the 100hp jets before I try it.

To be quite honest, I'm afraid I'll lose control of the car with the 200hp jets.

I hang out with guys using alot more nitrous than a 200 shot on the street. So who set up the nitrous? Was it done by a professional? It is a wet kit right? As long as your wheels are straight, your already rolling and you on a long safe empty streach of road, than all thats gonna happen when you hit the nitrous is a greater acceleration rate. I advise you go to your local tracks test and tune day for this. best possible enviroment for that kind of thing. You might get kick off the track though, for going faster than 11.4 seconds without a cage.
