Is there a fix for this how can we make the c7 stingray supercharged run without meth without having issues

blown81bu

U would def need a cam change for more fuel
I would still add meth theres just so many benefits to meth.
Meth is a must for that much power mho

Seannyc

Even with the z06 u need meth ?

So a cam and supercharger will be fine without met but meth to be safe

MikeLsx

Meth is never need, its only recommended.

Seannyc

Ok cool thx

C7&7

Like the guys said below you'll need more fuel. I've seen a couple 69x rwhp cars without meth but they had a cam with 32% fuel lobe.

Seannyc

Yah that's what I'm doin a cam with 32% more fuel

and supercharger later will that be fine to use it without meth or it's more safe to use the meth for the high compression

Try pushing 10 lbs of boost on pump gas with a stock engine without Meth......BOOM!

robert miller

In the passed I only used it as a set up for being safe with the tune if something happen. If you use it for just getting a bigger number to me really not worth it.

If something does happen and odds says it will sooner are later it will cost you a new set up in a motor for sure. If you play around with these car and find your cars best set up on getting a really good 60 ft you have more than not done. I say these cause most other guys then will blow the tires off of their car trying to get up with you.

Seannyc

Okay got it thanks for the info guys

From what has been explained to me the charge cooling effect is worth using Meth.


It cools the intake charge and gives you much more consistent performance regardless of pre-intake IAT.

wrong....

Higgs, I'm interested in your opinion. I'm getting an A&A supercharger installed soon in my 2014 Z51 (A6). I regularly track my car. I don't need crazy horsepower, but would like more than I have now. I'm new to this and don't want to blow my engine. I would prefer not to use meth or a new cam. I do expect to have to get a tune. I know that I may confront some heat issues, which I'll just have to address as best I can. Advice?

C7-Beast

No one can tell you if you will blow your engine due to Mods. Once you flash your ECM with a tune, you will no longer have a power train warranty.

When you say you track your car, do you mean drag tracks or road courses. If road courses do you find you need more power now? In other words, are there parts of the track you know you could go faster with additional HP? If the answer is no, I would not get a SC for the track. If you can't use the power, why send the $$

I went SC for drag racing and just general fun. I think you are safe with just a S/C if you keep boost down to 7 lbs. I think you can go to 8 if you can get 93. Anything more than that and you risk blowing up your engine with Meth.

I think the heat issues you are talking about are related to PD blowers like on the Z06. Typically, centrifugal superchargers do not have heat soak issues.

Good luck.

Magister Ludi

Thanks for the feedback.
My tracking is on road courses. (I autocross monthly as well, but that's not really an issue.)

Your observations are well taken. Smooth cornering skills will trump flat out speed more often than not. But I do get tired of having Vipers pull away from me on the straights. If I weren't getting such a deal on the SC, I'd probably spend the money elsewhere. But I just couldn't pass this one up. Thanks again.

Meth is a must..really..not recomended

Why some would spend 6000 on a supercharger and not 600 on a meth kit is beyond me...11.5 compression were dealing with here!
Its an easy install and there are articles on this forum how to install it
Cooler iats from meth help w detonation and a cleaner happier engine
U loose your washer tank for meth no biggie

Magister Ludi

OK, maybe my hesitancy is just because I'm a rookie at this. I think I know basically what it is and does, but I have no real world experience with it. Any down sides?

C7-Beast

The downside can be the cost. If not readily available locally, people pay up to 15 dollars per gallon for Meth. I pay 3.50 at a local fuel distributor. I buy it 10 gallons at a time.

Meth also burns clear so you don't see it burning. This can be very dangerous.

If driving normally, a tank of Meth should last 2-3 fill up's. Most people use the washer tank to hold the Meth. That tanks holds about a gallon of Meth.

The up side is it raises the octane, cools the incoming air, and sprays in the intake tract so there may be some minor benefits to the valve cooking that occurs in all DI engines.

Magister Ludi

So, no concern about putting a highly flammable liquid into a plastic container in a hot engine bay?

MikeLsx

Your right, its not possible to run 700WHP+ plus somewhat safely.......


All those cars that are stock and modded that run those numbers are probably going to blow up soon.
