Default Tuning question

So, hypothetically. If I had a 2001 z06 completely stock, except for exhaust and I had a shop put on a supercharger, vortech t trim with A&A brackets and #60 injectors, and the shop hired a tuner to come in and tune the car, but the self proclaimed "genius" "pretty much left the timing alone..." and now when there is blow by like a... well a lot of it. What all could be wrong... thanks for all of your input. oh yeah, have a boost gauge hooked up, only 7 psi.

You most likely broke a ringland. The stock pistons just won't stand for that kind of mistake. #5 & 7 usually go first, so start your leakdown test there.
Wouldn't it be nice if the genius paid for it to be fixed?
Surely all he'll do is tell you "no charge" for breaking your car.
Sad part is that Andy would have sent him a "starter tune" whereas all he had to do is dial in the MAF and VE and take care of any little issues.

Real sorry to hear about your troubles. Good luck bro.

Thanks man, I talked to the shop today and they blew my mind. They told me "we hired the moron, we will fix your car. No charge." so now the question is, what can I do since the car will be apart to make it safer for the future and maybe add some horsepower? Since the motor will be out I already told them to order a clutch, but I am still new to FI.... Any help would be great. Thanks again.

The Shop is G&R Hot Rods in Loveland Colorado. AWESOME GUYS!!

Considering they are paying, I'd chip in some $$$ for a forged bottom end(can't really expect them to go beyond repairing the stock setup you came in with)and some head work with dual springs, blower cam, and then let it eat!!!

Sounds like a stand-up shop, you got lucky!!

you got real lucky with that shop. Thats awesome!

Definatly forge the rods and pistons, lower the compression and get a blower cam. Also main studs and head studs would be good. Its apart so "do it once and do it right"

ECS and A&A both make great blower cams.

A blower cam will optimize airflow for the blower.
Combined with the blower, it may be good for another 50hp or more at the same boost level, depending on the setup.

As mentioned, ECS and A&A are great sources for blower-specific cams.

I can't believe the shop is standing behind their mistake. That's fantastic! Like everyone else said, Wiseco or Diamond dished pistons, good F/I rings like (Hell Fire rings), good double valve springs, new LS7 lifters, new lifter trays, high volume oil pump, double roller timing chain (use loctite on the bolts!!!)

This was exactly my point way to many shops just wash there hands clean of stuff like this and toss you the old "Its a performance engine, it has no warranty" line. Eventhough the people working in the shop dont have a ****ing clue what there doing. Ive seen it with my own eyes on two seperate occasions. Both engines had ring gaps .050+ and wiped out bearings with very little milage on them (this is just the start of the problems we found!). Always be very careful about where you take your stuff, make sure they have a solid reputation for great work and solid customer service.

Could someone put together a prefered list of proven products with prices for me? I'm looking at pistions, rods, rings, timing chain, oil pump, arp head studs, cam... am I missing anything? Thanks again for all of the help. Since the motor will be out I am going to do what is needed to make safe power, and plus it should save the shop some money since now they won't have to buy the stock parts.

Call Andy at A&A or ECS for suggestions. Both have good credibility and give sound advice.

Alright, so all of this added up to more than I was expecting, (shocking I know.) So if I don't bite the bullet and go all out, what would be the bare minimums that I should do while the motor is out. (Motor is pulled, 3 bad pistons.)

Stock block
Stock crank
Forged Rods
Forged Pistons
ARP 2000 rod bolts
Good bearings
LS6 oil pump
LS2 timing chain

These are just that bare minimums I can think of off the top of my head that you should do while the motor is out

I hate to say it but you might as well bite the bullet because you will get used to 500 or 600 horse real fast because were men....if you dont stop now it leads to a clutch, trans diff, heads, intake, tune....blah blah blah. It will bite you in the *** because its an addiction. You dont want to be that guy that gets 600 horse then gets beat down in a race and cant push the envelope much further without messing up what you should have done in the first place.....I hate being a man sometimes. Anyway do it all now or expect that you have a good chance of redoing it later.
BTW....get a great clutch now and you shouldnt have to for a long time.
just my .02...been there and still doing that

I was afraid that someone was going to say that, and that is what I am going to do. How are the spec 3+ clutches? Another question, how much boost will I be able to push out of my vortech T trim blower?

You might want to bite the bullet and get a Spec Twin if Spec is your brand of choice.
The T-trim with the right pulley should be able push 16psi easily. If you think you're addicted now, pulley that baby down on a properly tuned, forged motor.
