Highest horsepower?

[Coop[580]

Yes it is.

Cool. Must just be a lambda conversion based on a stoich of 14.7 on the dyno sniffer, I guess. Nice fat curves- any idea what the % ethanol is on that run? I don't know anything about the s19 cam, but I'm guessing it's fairly mild since the torque peak is still fairly low in the rev range? That would explain why I thought the peak number was a little low. A bigger cam would probably throw another 15hp up top, but then you probably wouldn't have that nice fat torque curve.

[Coop[580]

Yeah numbers wise i love it. Love the tq. I’m not sure what the % was. And the s19 is their custom cam for the zl1. The car just keeps going. It’s amazing. Tires soon Bc these stock GY suck. Not sure what i want yet... DR or just a nice set of mpss.

Put in 200 hp nitrous jets last fall taking stock bottom end and supercharger up to 900 hp at the wheels. Fried stock clutch first time at drag strip. Replaced clutch, then took it to Texas Mile last October and had a couple 188 mph runs. Went to Indy Airstrip Attack last weekend and had 158 mph on first run. It did 154 on next run and 122 mph on 3rd. Engine locked up at 30 mph. Oil was filled with small metal particles. Getting a forged assembly next.

I'm a little scared of it to be honest. Torque is what breaks stuff. I almost want to make the timing a little softer down low just to preserve the motor until I can build it to holds lots of power. With 812 at 3500, you stab the loud pedal and instantly convert tires into white smoke. The problem is that under load, that much torque might just turn my oil into glittery sludge also...

I know what you mean . My car is a monster as well. That instant.torque is fun on street. I will be investing in some r888 or some nitto r2 to help.

Is your clutch stock still?

Monster LT1-S clutch. I run Michelin PS4S on the street for just cruising to meets and stuff, and 15" Mickey 275 radial pros for when it's time to get down.

Jealous I need that rear setup!!

I am surprised by how well those 275 ET Street radial pros work. At 15PSI cold, the car seems like it would hook on sand. They seem to be a much softer compound than the ET Street R.

Good to hear that. I would just have to change few things to make a 15" work in the rear. Not sure what but I don't thing I can just bolt them on over the Zl1 brake setup.



PM some pics of your setup if you dont mind. Have a great weekend!

Mine makes around 715wrhp on e85 without internal work, no cam, factory heads. It made 703rwhp last time it was on a dyno, but I have change a good deal of things since then.
