Going road racing, will she survive?

Well, found out my cousin is a member at Motorsports Ranch, and he has offered to take me out and pay my fee's and I am stoked. The only thing I am worried about is the fact that I built the car aiming more towards drag racing, and I dont want her to let go on the course.

My mod's are in the sig, its a stock bottom end (freshend up) with 306 cam and all the goodies to go along.

What do you guys think?

Re: Going road racing, will she survive?

It sounds like your motor will survive being that you have a lot of it rebuilt and all. Also what type of suspension do you have? It would be best for handling if you had the proper suspension. For autocross it'd be better if you had the obvious, SFC's, strut tower, springs, shocks, struts, etc. Also what ype of tires do you have? The more grip the better. From what you have in your sig. it doesn't seem like the motor will be hurt. Just be careful about cornering and sharp turns (not sure what suspension you have). You also have the M6 so it will be easier to manipulate the rpms around tight turns and such. Have fun man and be safe.

Your brakes will get fried. I would put on some fresh pads before you go and they will need changed again at the end of the day. Keep an eye on your engine temps as well.
Had a friend who took his 95 Z out and did this one day, he had a blast and was passing the "porches" and even a viper once but he killed his brakes and the car was running hot.

Better get an oil pan,if ya don't have a Canton with all the trap doors.
Tires and brakes also and a fuel tank with plenty of baffles.
Good moly cage also(8 point at least and a seat and harnesse's)

Just want ya to be able to drive it back in the trailer or to the house.

Re: Going road racing, will she survive?

Its got Hal 12 way shocks all around (going to be rebuilt to "R" specs before I go though). I also have 315/35/17's all around.

I am most worried about oiling and cooling. Stock pan and electric h2o pump.

Stock brakes as well

That won't get it done..
Ya could go ride around and have some fun but the oil pan and brakes will keep ya from going fast and may do the engine in. If ya corner it very hard it is subject to loose oil pressure and ya ain't gonna have time to watch it,ya will be to busy steering and shifting and watching them other cars.

Re: Going road racing, will she survive?

With a little prep work, the car will be fine. Go out and have fun. Being your first time out, you won't be able to (and the instructor shouldn't allow you to) push the car too hard. Don't worry about the suspension or any radical engine mods just yet. Your time and money is better spent on the brakes.

Put on a set of new front brake pads from Hawk, PF, etc--racing compounds, not "performance street." I liked PF 90 compound when I had stock brakes but they aren't likely available any more. Pick up an extra set of rotors. El cheapos from autozone, etc, are fine. Paying extra money for fancy ones won't make them last any longer, these are cheap and expendable. If your rear street pads have a decent amount of meat on them, leave them as is.

Bleed the brakes well, if you've flushed them recently. If you haven't, flush the system with new fluid while you're at it. I use Valvoline Syntech--very good fluid, cheap and available almost anywhere.

Replace the PS fluid with Redline. It'll likely still boil over some, but the Redline will minimize it.

Keep a good eye on your temp guage. Depending upon how hot it is and how hard you run the car, the electric WP might not keep up too well. If it gets hot, just take it easy for a lap or two.

If you aren't running a good synthetic oil (or haven't changed it in a while) change it with something good--one weight heavier than you probably normally use is a good idea. I like Redline 10W40 for dual purpose use.

Other than that, go out and have fun. The car will be fine. The first few events are all about the driver. The car will take anything you're able to throw at it. If you want a good head start, pick up Ross Bentley's Speed Secrets. A very quick and easy read but packed full of good info. You'll have a leg up when you actually understand what the instructors are saying to you.

When you get hooked (and you will ), then you can start worrying about all the other things--and with more experience you'll be pushing the car a lot harder.

At the top of the list will be brake ducts (and/or an upgrade in front), an oil cooler, PS cooler, Canton pan, alignment (as much negative camber as you can get), stock WP if you're having overheating problems, rollbar (Autopower are good and SCCA/NASA legal), race seat, etc.

That's all just to make the car last better and keep you safer. Do that stuff before worrying about trying to go faster as you'll still be slower than your car at this point.

Good luck and have fun. Leave the ego at home and you'll learn a lot. You'll get an amazing amount faster in just a couple of events.

Re: Going road racing, will she survive?

I could only get 2 full speed laps in at homestead in 90-95 degrees before my car started overheated, so definatly keep an eye on your temp gauge.... And the stock LT1 brakes won't make it very far at all, I have C5 brakes with cooling ducts and motul brake fluid and I still boiled the fluid over, so definatly be very easy on the stock brakes, expecially since u dont have cooling ducts.
