New Procharger makes my Grand Sport feel like a new car!
Just got my car back from the shop with a new D1SC procharger, Injector Dynamics 1050 injectors, ATI balancer, 1-7/8" ARH headers and 3" catless x-pipe. She scoots now! Love it!! Thanks to Greg Connoyer at STG Motorsports in Granite City, IL and Tuning by Shane Hinds.

Since I've only had it one day with the supercharger, it currently feels bat of hell faster. We'll see how long that feeling lasts. It will sure roast the hell out of the tires though!

Does seem low for a D1SC? Even on an LS3....how much boost? Cam? Pulleys size? Fuel? Seems like your leaving ALOT of power on the table. My P1SC1 on my C6z is making 840whp on pump 93/meth. 3.7” pulley heads/cam as well. Definitely get a feel for the new gains but you’ve got a bunch of room to grow....like another150- 200whp and that’s probably conservative.
welcome to the F/I club man! Lots of knowledge and good info in the that section! Come drop by and say hello to the rest of the crazies lol!!
Car looks good, if you’ve still got the eagle runflats trash those things ASAP! Horrible tire and down right dangerous at 550+whp. Not a bad time to ditch the chrome wheels too lol if you are gonna get the potential out of that D1 you’ll need a smaller wheel size, 18’s at a minimum 17’s preferable. Not sure what your intentions with the car might be...1/4 mile? 1/2 mile...roll racing....just cruising? The only “best of both worlds” tire is gonna be the Toyo R888R it’ll hook a lot of power and you can still do some corning depending on your skill. The drag radials will hook the most power obviously but are pretty much straight line designated and the toyo’s will probably be the least “instant death” tire if you get caught in the rain. Personally wouldn’t recommend any of the tires above for wet conditions. 🇺🇸

Thats actually still on the low side money wise. He’s got a lot of power left on the table...like ALOT. Really just depends on what he’s comfortable with and what he wants to do with the car. D1SC on an LS3 and ethanol or meth is easily capable of 800+whp. He’s got the bulk of the money for parts/labor done, but to get the full potential out of that set up your looking at 15-20k thrown at the motor. That’s assuming he’s not doing all labor and tuning himself which he’s obviously not. You can save some serious money if you are doing all that but your getting into things like this can be a bit above most DIY capabilities and it’s a time consuming thing as well. Nothing cheap about corvettes I’m sure you/we are all aware of that....making them “fast..fast” isn’t cheap.....but when you do throw 20k at power mods on a corvette.....it’s a real damn problem for anyone trying to beat it.....ask me how I know lol

No cam, 7.5 psi, 91 octane. I know I can go bigger such as going with a cam, E85 or meth. Probably would need a better clutch. But all that costs more money. Feel like I've spent enough already. Maybe later down the road. It's not going to the race track, just wanted more than what I had. Puts a smile on my face.

Sweet GS! 6 hours to install headers tho - didn’t even take me that long in my garage on jack stands to install LG longtubes, catted x-pipe & Corsa Xtreme axle-back.

Thanks! Ya, perhaps it didn't actually take him 6 hours. That's what he quoted me for an estimate and ultimately charged me. He does really good work and is very communicative throughout the process. So, I wasn't going to nickel and dime him.

Congrats on the new supercharger.
Although I have a different SC than you, I am still happy with the performance a SC gives right out of the box without a change of drive pulley, headwork or aftermarket cam.
Look at it this way, at 550-560 RWHP, you are putting just as much, if not slightly more HP to the ground than a bone stock C6 / ZR1.
