What did it make with the roots blower? I'm making 436rwhp on pump gas and 471 on VP110.

What kind of compression are you going to set the new motor up at? Something in the 9-9.5 to 1 area?

CHP shows the compression at 9.2:1 with the 58cc heads and a 4.030 bore. However, I don't think the block is going to need to be bored. I think we'll be able to just do a hone on it but Eric will have Speed-O-Motive confirm that when he drops off the block. I'm kind of hoping it doesn't need the bore so that the cylinder walls will be thicker for a little more strength.

On that engine dyno, it made 556 HP with 8 PSI of boost. I never put it on a chassis dyno. After running it for a bit, I slapped on a smaller pulley and melted a piston when I tried to tune it on the street (should have gone to a dyno tuner). I was able to hone the cylinder and replace the piston. So I installed the water-meth kit. I took the car to a dyno-tuner and couldn't get it to work. He kept telling me I was having spark blow-out. I left in frustration and figured out I had installed the injector nozzle backwards. So I tuned it myself on the street and was able to run 26* of timing.

So, I guess the answer to your question is, I don't know. I would guess somewhere ~500 to the wheels. I know it was a monster!!

Wow, that's alot of timing with boost. I only have 16* at 6000 on the pump gas tune. That thing must have had a ton of torque with the 427 and a roots.

I think Eric's engine is going to be real fun in his car. I see third gear burnouts in it's future! Or maybe a broken T5.

As long as he doesn't put sticky tires on, I think he'll be fine. If he does put sticky tires on though, then I see a broken T5 :judge:

Ron, what's the curb weight on that thing, like 3000lbs? It's going to be a beast when you're done...

I'm not sure. I know that the LX is supposed to be the lightest body style next to the LX notch back.

I'm pretty sure it's about 2900.

Power to weight ratio is lookin pretty good :drive:
