im choosing a head unit atm , my tuner says a corvettes sweet spot is 650 to 750 he says after that you really start to break stuff .

so I figured I would get the opinion of my fellow vettes , I plan to street drive my set up quite a bit , no off season here in texas so ill be driving it 2 or three days a week . I do some roll racing and texas mile events along with spirited street driving next to other quick cars

is 900 plus too much for reliability would 750 - 800 be better and all ill really need

im coming from a h/c/I setup making 478whp

opinions please guys , thank you

One guy in here has a good YSI unit for sale now get it low boost big pulley on it and have some fun. On a 100% stock car keep the power no more than 600 rwhp. You will start trans problems more than that. Put in a new set of good V/springs in the heads. Robert

Your tuners idea is pretty close to my experience. When I went over 700 on my first procharged C5(98) I broke about everything. I stuck with 650RW the second time around on my Turboed 03Z and it held up like a champ. I did kill an engine, but that was totally a tuning error on my part.

In my opinion 800-900whp is where these things seem pretty happy....

What a tough question. This depends on tons of factors and how exactly you want to use the car. Personally I'm at 600 rwhp 93 pump only 9 Psi on stock bottom and can dismiss quite a bit on the street.

Ive driven the car on multiple trips from Ohio to Chicago, Bowling Green KY, Nashville etc getting 25+ mpg and havent really had any issues. Street tires are decent from 40 on in warm weather but radials are preferred. Now I'm getting greedy and want more so I bought an Alky Meth kit and will upgrade the fuel system.

Trans- 6 speed (T56 based) give or take a bit try to keep it 750 or less rwhp. Might be able to push a bit more if all you do is roll racing but make sure you have some upgrades and the strut kit. The PFADT and now Hoosier dif brace is also another good option to add. All of this with a good clutch. Want more power with a reliable trans? Tr6060 swap.

Auto- I'm not sure


I honestly have no plans to push past 700 without a forged bottom end or 850ish with one.

I'll say the "Sweetest street spot" In my opinion is around 800 rwhp with a nice drivetrain, fuel system, forged motor with meth or E85, and drag radials.

At the end of the day theres always somebody faster and with much deeper pockets.

thanks Robert , im probably going to just send my 1500 bck to ecs its new and pay 500 and go sl2200

thanks for the input man its appreciated

thanks for the input man its appreciated

its got a built block 370 tms built , ecs fuel system , gonna be on e85 with a stage 4 mn12 with a viper main shaft , pfadt trans brace is in the build as well , I have a stock diff and torque tube though

consensus seems to be with the 1500 I will be between 750 and 800
with ported heads and boost cam full exhaust innovators west 10% od crank pulley

just want it to be somewhat reliable , I don't need to beat everyone or be the fastest just want to hold my own

Perhaps the main problem with the T56 is fluid starvation (no pump) and buring up under heavy load when the fluid is pushed to the rear. Yes the mainshaft upgrades and billet keys etc will surely help. (I rebuilt mine with the 9310 mainshaft,billet keys, bronze pads etc) but the t56 trans also has physically smaller gears than a Tr6060. BlownblueZ06 knows much more than myself on this. The C5 Dif aint exactly the strongest in the world either... 750-800 you will definitely hold your own and should be pretty reliable with those mods

I been at 600 to the wheels for 7 years now never a issue with a Novi set up. It's more then you need for the street.

800-900 is a sweet spot for sure

blown81bu

That makes me feel better.lol..914

DANZGLASS

as much as you can handle. 840whp seemed real good. But it wasn't to much to handle. Just have to get the right things to support the power you make. Motor,trans,diff,clutch,tires boost control if turbo like me. Im shooting for 9-950 pump meth street use, max the turbo on race gas.

I ran 800 at the tire and it was useless on anything except drag radials toned it down to 600 at the tire and it will hook pretty good even with the older Toyo RA1s

that being said I want to go back to 900 at the tire and try boost by speed to allow the power to ramp up and hook

beyond that I will likely run out of both $$$ and courage

be VERY careful with High HP beyond what you have traction to control!!

ask me how I know.

I have not yet put my car on the dyno to see where it is HP wise @ the current 18psi, but I can say the car is more fun on the street @ 14 psi.
I do run a drag radial 100% of the time, but on the street unless I really put some heat in them, at 18psi they are useless.
Kinda sucks that I just spent a ton of money on a new forged motor to run more boost.....lol.

TracyRR

It's never enough, lol!

I hooked 850 just fine on my 345/35/18 MTS. Also hooked fine with the 325/40/18 m@h drag radials. With better boost controller and bbg I don't see issues with traction at 1000-1100. Al's know how to control that right foot helps.

I like 600 rwhp if you actually want to use 1st and 2nd gear. 800-850 rwhp is nice for a roll racer 3rd gear and up. I've had no luck with 18" drag radials in the lower gears on the street with 700+ hp.

knightz06

Thank you guys for all the comments and advice its much appreciated !!

DANZGLASS

Dead hooked second with a little heat above 60* out. 840whp on 18s.

knightz06

That's exactly what I plan to do , nothing like a mn12 40 roll !!!!

What drag radials were you running ?
