I’ve been on the forum for a few years now, learned tons! There are some amazingly fast modded Vette's on the forum. My question is for the experienced guys that have improved on the performance of the already amazing C5, . Okay, provided that a person has the traction and the drivetrain to handle it, how much rwhp and rwtq would it require for the average weight (say 3250 lbs) C5 Corvette to reach a 0-60 in 3 seconds? I’m guessing maybe 500-600 hp? I just don’t have the experience with modded Vette's. With new C8 Vette’s seemingly able to do this stock, I’d like to be able to keep driving my C5 with some of the levels of performance of the new C8. It might be too expensive to even come close, I don’t know, that’s why I need the forum expertise, to most likely calm me down.

Definitely interested in this, hope you get some replies

thanks me too!

It's not the power is getting it to the ground. It's the physics of it. There's a reason a C7Z06 can't beat the C8 to 60 with 150 more hp. I would guess 550 whp and Drag radials on a prepped surface. On the street is going to be really tough.

My old motor was south of 500 hp and looking at my HP Tunner logs along time ago, I remember being below 3 seconds with high 1.4 and low 1.5 sixty foot times.

What surface? What tires were you running?

It can't be as impossible as some are making it out to be. With the right mods, I'm sure it can get the job done

My last track outing was 3.15 0-60. (0-100mph = 7.479 seconds) A bit of a bog on the launch, I think the car, if I left off the bottle would be sub 3 seconds easily. This was NA on the 0-60. Head/cam/supporting mods. Baby Hoosier tires (9.5" wide). 1.67 60', ~460whp. The 0-100 had a 50 shot of nitrous on it during 3rd gear. Car ran 11.3@126 out the back side in the 1/4.

Essentially a c5 needs 450-500whp and a good launch to crack 3 second 0-60. Same/similar power puts it low 7's 0-100.

Next time out with the Mamofied 102 I've installed and the 100 shot, I'm anticipating 0-60 in the 2.5 range, 0-100 in the mid 6's, and probably a mid to high 10 around 128-134mph.

Was at tracks (Gainesville Fl, SGMP Valdosta Ga, & MIR..Maryland)...all well prepped tracks. Tires were 17" ET Streets with 12-13 psi. hot

I just found 2 logs from my 3,925 lb truck with 498 rwhp and my zero to 60mph time was 2.904 and a 3.064 (both runs were between 10.904 and 10.93 et with low 1.5 sixty foot times). Truck is NA on slicks with 410 gear.
My zero to 100 mph took 6.967"

So doing a sub 3.0 in a C5 vette is not that difficult. Pretty much all in the sixty foot I would guess.

Thank you for your input! Hope this helps the OP. I know it sure did for me

Welcome.
I can't put my hands on my old vette logs but I found dyno sheet. It was 481/434tq, running 390 gear. I believe it was a 2.7 time, zero to sixty mph for my best. My weight was stock except for tires and front rims.

Awesome! Thank you everyone!

Back when I had my car we didn’t have all these fancy draggy type things, so we had to use calculators based off of time slips. My car with a 1.74 60’ put me around a 3.7 0-60 with 315whp.

red03vette

that’s impressive! Thank you! I’m assuming you were using pretty sticky tires? Interested in your setup at the time.

slowtealz28

It was just a bolt on car, ebay headers, vararam, stock heads, stock cam, LS6 intake, ported stock TB, ebay catback, built trans, spec twin clutch, built diff with 3.90 gears. Drag radials and GTO spares on the front. Super simple, the highest the car dynoed before the built trans a diff was 333whp.

Krusty84

Using the dragy I got a best of 3.90s (3.66 w/ 1ft rollout). Same run equated to a 7.78 @ 95 in the 1/8 and 11.85 @ 121 in the 1/4.

~420-430 rwhp, '84 C4, 6.0 LS swap.

Using the Wallace Racing calc with my 1/8 e.t. and trap shows 3.1s 0-60 which is obviously way off.

A ~1.6x 60 ft time backed up by ~95mph 1/8 trap is likely a ~3.0 or slightly quicker 0-60.

Money wise, you're looking between 4-7k doing it correctly and depending on who's doing the labor.

I'm a 03 with a 408 stroker na at 520 on the first time on stock size rims 295/40 nitto nt05r. With me and a roughneck buddy with a stop watch we're getting 4s and spinning like crazy. Now with the new throttle body and re tune max effort 598/561tq it's really spinning. Can't wait for my wide body new rims and rubbers and see what draggy says. Like you said. Getting it to the ground is the challenge. It's got me questioning if I really wanna put on the spray and f1x I got waiting for a chance to go on

red03vette

that sounds like one heck of an awesome Vette!

PRE-Z06

Iirc my old sleeper SBE C5FRC did a 2.8 0-60mph at 420rwhp and 4.10 gears on a 1.4 60’ at the dragstrip on an 8.5” wheel with ET Street, that of course included a shift to 2nd. Think my headers only C6GS that makes similar power is a 3.1 0-60 when it cut a 1.5 60’ on a 9.5” wheel with 275 drag radial as it has 3.42 gears and is around 200lbs heavier.
