Recently had the car dynoed with mods in signature. A stock C7 made 377 on this dyno and a Hellcat made 609...so it appears to be 30-40 hp lower than the average dynojet dyno from what I've seen. Anyways I made 415/385 n/a, and 518/640 on the 125 shot. I wasnt expecting 250 rwtq on the juice lol. This would probably put me at 450-460 rwhp n/a, and 550-560 on the spray with closer to 700 rwtq on a average dyno. Minus the huge torque this is about what I expected from my setup, even though it seems to perform better in the real world than the numbers it puts down.

Also ran into a newer style GT500 on the way home last night as well. All I could you is that it had exhaust and a loud blower. Regardless, I drop down to 3rd at around 60 and,wait for him to do the same. I honk it off, and get a solid 1 car jump. He basically is right on my tail the whole time, but couldn't gain on me. I shut down around 125 at the top of 4th. Would've loved to know what was done to the Shelby lol

Have you made any passes yet? Sound like it runs good...would be nice to know MPH & Weight for comparison.

Only made one pass n/a and that was when I had a horrible tune and the old LS6 intake. That day I ran a 12.2 @ 118 I believe. That was n/a of course. It has more in it now I'm sure. The car also carries an extra 100 lbs with the iron block. I have no weight reduction either

Regardless, it makes enough power to be a drivers race with my buddy's ported and pullied 03 Cobra that makes 500 rwhp. Plus his car has close to 200 lbs of weight reduction

Do you actually believe your car makes 640 tq on a 125 shot? Lol!

Well that's what the dyno said lol. The clutch didn't slip and there was no break in the graph due to overspinning the rollers or anything like that. I know it sounds crazy but that's exactly how it played out. Even with 315 BFG drag radials it spins bad from a 2nd gear roll. Doesnt matter if it's warm out or not...it spins hard in 2nd. I've even spun 3rd a tiny bit on a cooler day

I think you have a good combo & I'm sure it's a beast on spray.

Could you post the graphs?

Thanks man! Yeah I have to say it hits a extremely hard for a 125 shot. I don't know why...can't explain...but I'll gladly take it lol. I have the graphs in my car somewhere. When I get back to my car I can post them

Did you have the Car Guys tune it? How many pulls? 415/385 seems low for a 370, thats about what my 5.7 did! & I've had it on vectors mustang dyno. Read just a lil lower with stock heads

Yes it was the Car Guys dyno but they didn't tune it, but like I said that C7 made 377 and the Hellcat 609 so it just reads really low apparently. I've seen a C7's make around 410 and a Hellcat make 653 on dynojet dyno. We made 6 pulls within an hour so it was heat soaking I'm sure
