Hello everyone, i am new to this forum and a new corvette owner in general. my beloved 2003 mustang was totaled(not my fault, got the other insurance to pay for my losses) and thought it was time to move on to something different. and as my dad says, corvettes are the best car on the planet, and now that I've had mine for a few months, i can not disagree with him. Anyways that was my intro, so here are my questions:

i have a 2002 z06 and i am going to supercharge it very soon. it is stock right now except a vararam and a short shifter. I am going with the v2si A&A supercharger kit, longtube headers(no cats/midpipe), and an methanol injection system. I'm planning that this combo will make somewhere around 600 rwhp. which i know is a lot for the stock components of the drivetrain, motor, etc.

what mods will i need to do to make this car a bit more reliable. granted i don't drive this car everyday, i do road course 5-6 times a year, but i don't think i will be doing that anymore after the supercharger setup. so probably just the drag strip 2-3 times a year.

so back to the question. what will i need to replace to get my car to hold the power its going to make? I know i will need a clutch for sure, i heard the rear ends/axels are pretty strong, but I'm not too sure about the transmission, or components of the motor. If anyone can give me any feedback i would really appreciate it!

Thanks! -Brandon K.

Valve springs and I would do the trunion mod on the rockers.

can you further explain these two mods and what they do? sorry I'm really new to this. and also why i need to them. id really appreciate it.

thank you

Good tune is most important. I'm not sure where you are in the country but maybe call A&A and get their recommendation for the best around your area.

Meth is a good choice to help hold it together.

Brandonkirk1994

yes, i already got the tune part covered, i am going to get it installed by a local lsx specialist, and the car will then be tuned by his partner in the business. Thank you though, any info helps. i pretty much got it narrowed down to a new clutch, and valve springs. If things take a turn for the worst, I'm hoping the heads/ valve train are unharmed and i will be going with a fully forged bottom end. But i understand if i have a good air fuel mixture from the dyne tune i will most likely be fine. i was just wondering about extra precautions short of going with a forged block that would help the life of the motor. thanks!

If you are going to drag the car, I would get a DTE brace and a diff output shaft upgrade. I would go Mcleod RST / RXT for your clutch. I make 640 WHP on a T Trim, on pure 93 octane, stock bottom end, heads, and cam... And the RST hold the power just fine, and has a stock like feel.

What fuel upgrades did you have with that setup?

95rtturbo

ID 850 injectors, and just a BAP.

Brandonkirk1994

Thank you for your reply. And thanks for the information. I was planning on using the stock clutch until it gave out then upgrading to the rst twin disk or a monster clutch. Now that you have told me about these other parts I will put them on all at the same time since they'll already be down there. Are there any other mods you did besides the clutch, differential brace, and hardened output shaft to aid the supercharger?

95rtturbo

I didn't even do the diff brace or the output shaft since I don't launch the car. I probably will in the future just to be safe.

The only extra things I added (other than what was in the A & A kit), were poly motor mounts / tranny mounts, the Tick Master cylinder, a new GM slave cylinder, and the lightweight Mcleod aluminum flywheel. I just ordered a new set of Toyo R888s. You will need sticky tires for sure.

I already had bolt ons prior (AR 1 7/8" LTs with catted X pipe and Halltech).

Brandonkirk1994

Oh okay. I have long tubes that I recently purchased that will be going on as well. I Also already have drag radials. I'm not sure how often I will even go to the drag strip. I'm positive the car will run quicker than 11.50 in the quarter and I am not interested in putting a roll cage in my car, so i guess I should consider if I really need the diff and output shaft since I will not be launching the car around.

95rtturbo

I would just to be safe. With drag radials, you could probably hook hard enough even on a low speed roll, and cause damage.

Brandonkirk1994

Okay. Thank you for your advice. I appreciate it.

My recommendation is to spend the extra 350 bucks on the V3 T trim. You will be happy you did.

95rtturbo

Agreed. I'm glad I took that route. Very small price to pay for a more potent head unit.

Brandonkirk1994

May I know why? I can always just go with a smaller pulley on the si trim if I ever needed more power. Which I doubt I will be saying at 600rwhp. And if I do then wow, do I have a problem lol.

MVP'S ZO6

I I had a dollar for as many times as I've heard that exact statement in bold or something very similar, I would no doubt be a millionaire.

On a serious note, 600 WHP is achievable with the right combo no doubt but with a T-Trim blower you won't have to work the blower as hard and it's still small enough for a stock or near stock engine combo. Give yourself a little breathing room. :-). Smaller pulleys are fine but each time you drop a blower pulley size the risk for getting belt slip goes up. Then you have to start looking at things like secondary drives.

Just my 2 cents.

Brandonkirk1994

Yes I understand haha. Is the t trim from A&A carb legal though? That is another dilemma. I was under the impression that just the si trim was. Thanks!

MVP'S ZO6

Technically anytime you change the pulley or anything from how it's listed on Andys carb cert it's not legal.

So, if you go to andys website and look at the carb cert for his blower kit it covers very specific things. Any deviation from that technically makes the cert invalid. Cali is a B.tch

On that note, the t trim does have a carb e.o. Number.

Brandonkirk1994

sweet. thank you very much, i will look into getting one of those now. another question i have, what is better or which do you think is better? the v2 or v3? the self contained unit or the one that draws from the engines oil pan?
