Went to the track last Sunday

[GTPpower]

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.

[Nighthwk12]

very nice

Good run

Can you tell me what Cam and which Pulley you are running.
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.

That gives me confidence in running nitrous on my own.

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.

Thats awesome!

[Silver2kgtp]

Very nice!!!!

Not blaming anybody if it breaks but this gives me more confidence in my trans! I have the same milage too. I was always nervous to go above a 50 shot especially with my new turbo setup. 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.

Yep, you guys tried water/meth injection ? I homemade my setup but its all the same stuff. I also have the mixture spraying on my intercooler.
