I will say this for the A6 - it's going to be a lot cheaper to rebuild the 6L80E than the 8L90 if the non-Z06 version is less stout.

This is a good post and should be ongoing. Right now my plan is to turn up the boost from 8-12 lbs towards the end of summer so if the motor ***** the bed I,wont be without a car for the summer.
The lower end ,crank and rods are forged and should be fine . Those Hyperutectic pistons ,not so much! Right now Its about 580 rwhp @ 8 lbs boost .
From what i see written here the future of my motor looks bright .Although based on our experience with our GN and Camaro I will be surprised. We do have a new tuner( Slowhawk in Mass.) maybe that will give us some longevity.
Im keeping the checkbook , " locked and loaded" ,just in case. Jim

There's actually a lot of faith being put into those pistons by respected builders and shops. That being said, even I wanted to swap them out...

The amount of detonation is the key factor in seeing how much (or little) damage is done. They didn't do us any favors in shaping them like that, either.

My C7 is at the shop getting an ECS/Meth/Headers so to say this article gives me a knot in my stomach is an understatement.....

And a quart of oil in the intercooler!? Yup I'm definitely going with a catch can...

Trans C7

A6 is doing fine, just have to have the right calibration, thanks Redline

Don't most blower kits have a catch can anyway?

ChucksZ06

It is the tune, ie how well it is done that is going to make the difference on the engine holding up or not. Not saying forged rods and pistons are not great insurance.

No sir they do not. At least none of the kits we have seen so far do.

DOUG @ ECS

Several 700+ C7's out of here going strong, 100% stock engines. Only instance of oil usage has been on the road course from one vehicle out of three I know of so far. It's fine, just burped a little.

Indeed but it's a cheap thing to add, mine was $150 from Might Mouse Solutions for my C5. $150 is a drop in the bucket compared to the money spent on a blower/meth/etc.

Same thing Chris told me

Gadfly

It was full of oil because it went boom...

SinnerC7

so you're hitting 672 with completely stock motor? the guys who tuned it did a great job getting enough fuel with the stock cam and fuel lobe, who tuned it? do you expect to up the boost more with the stock cam even more?

I dont plan on pushing mine much over 700whp. Im not easy on my car either.

Better check your C7 out in stock form first. If you pull your intake bellow infront of the throttle body and find oil. I would not add a blower kit. My car has been sitting as I struggle with the oiling issue.

Oil comes out the BOV. If you car is oiling and you add a kit your going to have issues. I even have a catch can. It just a bandaid for a non healing problem. In the next day or too I hope to figure it out with new info on how to fix it.

I can clean it all out. Then have the oil down a qt. Drive it 20 miles and have oil everywhere. It sucks!

Sounds like you might want to get a second opinion on your setup....installation error. Maybe they thought it would be a great idea to boost the crankcase instead of the combustion chambers.

There are plenty of boosted LT1s (and DI truck variants) out there with no issues, which means its your car as the anomaly, not the norm.

If you your issue is really that extreme, Corvette Forum is not where I would be right now.

i had a lot of oil in my intake when i had the blower put on at 1500 miles. When i got my blower on it was doing what yours is just out of the dry sump tank not the bov. Ecs sent me a new way to route the pcv system and it fixed the issue.

I have the instruction's from ECS that I'm doing right now to get it ready.

A&A must route to the stock location (airtake tract) for the EPA cert.
My sump was routed to the intake with the PVC lines.
They used to route to the airfilter or box like ECS. I'm changing mine over to the ESC style. Hopefully that will fix my problem.

Sounds you might want to search and see that the oil issue is common with stock and nonstock cars and stock owners, several
here have catch can on the stock car. Might want to do that instead
of looking silly by suggesting it is an install error!
Then my car is the only one?
Forgetting that GM has a servive bulletin out for this issue too?

Since A&A installed your kit, have you discussed with them what would be the best solution to your venting issue, and possibly of others that have their kit?
