Yes this is a different black LS3 Camaro SS than the other video, that one was H/C/I auto. This one is cam only 6 speed.

 

Damn good runs! Close races are the best.

 

did i see a NLS??

yea ive done it too.... lol.... cant resist

good runs!

 

Good vids ii always like your vids lol

 

Wow damn nice runs!!! gotta love the close runs, they always keep ya on the edge of your seat, lol

robk

 

Im assuming race gas cause no e85 or no fifth injector to run E?

 

This is about what I thought would happen - good pull with a slow reel-in up top. Great races, well matched drivers and a great comparison between both cars.

And good job on actually catching VISIBLE night runs!

 

Wow, very nice! It really moves out.

 

Damn, that camaro moves considering I know how fast your car is LOL. Good runs. There's a lot of videos now with the ZFR

 

how much power is that car seeing

add me on facebook if you wanna see it yoan guzman

 

I dont understand shouldnt the cobalt be pulling the camaro bad? Is that a small turbo? Camaros are heavy and even with the bolt ons it seems like a turbo upgraded c16 lnf should have still pulled him. Vettes are good for mid to low 12's and they weigh about 2-300 lbs less than that camaro WITH the ls3.

What numbers and 1/4 from the cobalt and camaro?

 

It's a cammed/bolt on 4th gen with an LS3 sitting around 470whp, with a weight of around 3400lbs I would assume (without passengers). That's not heavy and it surely makes sense that it pulled the LNF up top. The LS3 has a much better powerband.

 

Great runs!

 

Exactly my point. Less than 500 whp, 3400 lbs vs a cobalt that should be running close to the same power numbers weighing in at 500 lbs less.

Makes no sense that the camaro pulled the lnf.

 

Well the Cobalt pulls initially (power-to-weight), but then the Camaro pulled up top (higher hp). I see nothing unusual here.

It's the same reason we can pull bikes. They'll pull hard at first because of power to weight, but get up to high speed and the tides turn in favor of the car with more power.

 

you can have a 440rwhp 4th gen and run in the 10's.

fwiw

 

The Cobalt is probably sitting around 415ish whp.

Without pushing that turbo hard and running ethanol, it's not going to make the hero numbers. We also don't know who is doing the calibrating.

Either way, the cobalt ran hard and it was a great video.

 

Since this was on race gas, I'm going to pop the E question...

Would the ZZP cams provide enough additional fuel for running the ZFR at say 27psi, without having to use a 5th injector?

 

Maybe, maybe not. With how fast the turbo spools the issue would be the needed fuel at the 4000 rpm range where all the torque is getting made. The cams can support 475 ish hp on e85.

 

i'm almost certain he will be doing e in the future. we have it right down the street from us. lol

 

Well, I may be joining the ZFR club here soon if I can figure out my hotside CP fitment issue, so I'll be staying tuned here to hear how it goes on E.

 

I've used E47, at about 25 psi is where the stock fuel system is maxed out. I hit 415whp 435wtq on that set up. I've tuned for 100 octane at 29 psi as well maxing out the fuel system too. Maybe in the 450whp range. I'm pretty sure the cams/valves and fuel lobe will provide enough fuel. Ford is running full e85 on his s256 at 28 psi at times. He hit 500whp.

 

This is good info. Thanks!

 

At 27psi and race gas that car should be closer to the 440 mark. A local here is making ~410/425 on e47 and 23-24 psi.

 

I forgot to put that he had cams in the video...oh well. He is running race gas because we are down at TX2K and he wanted to **** **** up. Tune is still conservative, 450ish whp. It's only 102 octane because the 110 he bought was leaded and couldn't run that.

He's already got a couple quickies in down here, I'll put together a video after the next 2 nights of racing.
