Thread: Went to the track last Sunday

Best pass on a 125 shot:

Grand Prix GTP vs. Z28 LT1 Camaro - YouTube

DA was about 4K feet on this pass.


Was going to spray more, but I ran out of nitrous.

very nice

Good run

Great times !

Is the transmission still 100% stock ?

It's an XP cam on a 3.0 pulley.

The trans is stock, but I did drop the pan, change the filter, and stuck a couple spacers in the 1-2 accumulator to make it shift a little quicker. Other than that, bone stock with 163k miles of abuse.

Do you baby it off the line ? or do you do anythign special to make the stock input shaft last... ?
What kind of tires are you using ?

Nope, I spray the whole shot right at the line, all the way til the end. Probably going to put a progressive controller on it to help with traction and be a little easier on the trans.

Shock load is what breaks input shafts and drive chains. Keep your shifts as soft as you can. Sticky tires with a big, squishy sidewall help a lot too.

The slicks are MT ET Drags 26x10 15".

I've got a few passes in the 11's, lots in the deep 12's all on this setup. But, I do trailer it to the track, because I'm sure something could snap anytime.

Very nice!!!!

What about your CV axels? Just using my nitrous i messed up my left one so bad it was pulling my car to the left!

From what I have found, it's best to keep stock ride height in the front, and a good set of GM axles. I've never broken one, just had the boots tear from weak springs. I think most break due to incorrect suspension geometry. Keep your geometry correct, and I doubt anyone here makes enough power to break a stock GM axle. I'm pretty sure MattM was running one stock grand prix axle, and one stock Berretta axle.

Not many guys risk stock transmission on a powerful set up like that.

No problem. Let me know if you have any more questions. These cars really love nitrous, and I'd like to see more people using it.
