I'm sure that some of these issues have already been addressed so thank you for your patience. I have a Z 51 and wondering the money I have to put on the table to have a well done and reliable job done. I'm know there is more involved than bolting on a supercharger unit, I.e. Pipes, tuning, intake etc. I track the car and finding more Gt-3, Porsche turbos, cup cars in my class and want to stay competitive. So my questions are: the financal lay out. Who in the Maryland area is well versed in this type of set-up and finally how reliable in terms of longevity can one expect given they respect their equipment and don't abuse it. I'm also questioning whether suspension changes are needed? I find the corvette to be very well balancezd. I run both on short tracks but want the power for Watkins Glen, VIR, and Mid Ohio. Thank you in advance for your feedback.

If you want 550-600 rwhp its $6500, if you want 650-700 rwhp its $11000, if you want 800-900 rwhp its about $20k.

If you want more power as a track car, you are best off staying naturally aspirated.

You can get an easy 100hp increase from a cam, headers, intake all tuned up. That's really a significant increase. If you take it to the next level with a full build and displacement increase, you can get well over 600hp.

The problem with aftermarket superchargers on a track car is heat issues. The Z06 is the only one engineered to run boost around a track.

If you are a competitive track driver, stay NA.

My Z51 is at East Coast Supercharging right now. I am going for reliable drivable street car set up. However, they can tune for any situation and the kits they use are upgradable. They are in south NJ, so not to far from you. There was a car there with a Maryland and Virginia plate today. However, I was only C7 but they have done a bunch. Lots of C6 Zo6 and ZR1.

About $7k with a chassis dyno incl/tax.

Ecs has got my vote I love my set up drives like stock

C7pimp, I bought the C7 because it is NA. What do you estimate the cost of cam, headers, intake tuned up? I'm also from Virginia.

Should be about 5000-6000 for a cam, headers, intake dyno tune. Depends where you take it.

Question , For a C7 automatic, Daily driver(To drive cross country)PUMP GAS, Are the superchargers ECS or whoever(550-570RWHP) VERY reliable,meaning to even do a near top end pull once in a while? Not talking about track use, Just to run her up on the pump gas tune now & then(not back to back runs) & be RELIABLE as to nort have a melt down?

I had mind tuned for maximize drivability and reliability. I don't daily drive it, but average 5K miles years. I wanted to be able to get on it about as much as do now and, without worries. I don't do drag or road course racing. I believe they have a few folks running this kit as a daily driver.

My car is tuned for 91/93 octane (pump gas), just like a stock vette. There was a half tank of Sunoco Ultra 93 in it when dropped it off and about that much when got it back.

I know the stock manual says you can run regular for emergencies (87/89). I wouldn't do that with a supercharger, I will defer to Doug at ECS to confirm if safe in an emergency, assuming kept out of boost.

I paid about that for ECS install and dyno tune.

I see where one said he had A6 tranny troubles afterwards, Is it a norm for this ? or are others having good luck with there trannys holding up?

dironvictorious

I didn't have tranny troubles. I misread dyno-graph due to nature of an automatic. There is always a spike as car shifts into demanded gear, and that can throw off conversation ratio. There was another poster that said he had trouble on the A6 in his C6. I believe the A6 in the C7 is stouter and incorporates many improvements for the 6L90 in the CTS-V/Camaro ZL1.

I lot this will have to do with how drive. I suspect for a street car, will see boost and increased torque/power for occasional short bursts. One run down drag strip with a hard launch on even a stock car will probably be more and tear than you see in weeks of even spirited street driving
