Haha. I can in here to call my wife, and checked here. I knew there was a thread on this. Yeah, the kit Mario has is like that. You loose a good bit of ground clearance though.
I think 500rwhp or very close at 9psi is possible if the heads are what the porter claims them to be. We'll see.

we killed the clutch after about 10-12 pulls

But this thing screams on the dyno, it ONLY made 404/39?, but was still rich and we didnt get a chance to add some timing.It was a long day, mainly cause Dustin had to "fix" the BS carb that Performance Carb did for me.It was made for 20 psi and 1000+ hp so it was too much for mine.Rich and Dustin didnt give up tiull the clutch did

Ill get some vids up here in a while

That thing sounds way better than 400hp to the wheels.......

Next time you go back, put a set of slicks on it to make sure you aren't breaking traction on the rollers.

Your car makes power really fast... you could be over powering the tires on the dyno and getting a false reading.

Bingo. I've heard 400 hp cars before and that doesn't sound like a 400 hp car.

that dyno pull wasn't like any I'd seen. What type of dyno was it? Did you spool the turbo then hit the load on the brake? It seemed a bit fast. where did you start your pulls from?

in 4th gear , i think Dustin had it about 22-2500 rpm and nailed.It revved REALY fast even before the clutch died.

That carb was extremely fubar. PV in both front and rear, both PVCR's over 5/16's. Was shooting ducks pretty bad the first few pulls. Had to block the rear, and make the front PVCR's smaller. All the way to .059 and knock jetting out before we could even see the A/F. It was taking a good nose dive when the clutch would slip, then it would level out. The carb has HUGE venturis causing the A/F to nose dive. I know it's making tons of power, clutch just won't hold. Never smelled it though. But it was confirmed when we did a back to back test and the RWHP dropped 50. Took a little bit to figure out if it was the clutch, or the extremely rich A/F.

the pvcrs were 5/16" WOW you must have had some gorilla holley "tuner" working on it earlier. I thought you just plugged the pvs and jet it up with a blowthrough setup. Those pulls looked extremely quick and I wouldn't be surprised if the dyno didn't apply the proper brake force, the clutch and/or tires slipped, or some combo of the three

Noooooo. You need them. If you block and jet up, you run around town with 80's in the front and probably 10-1 AFR. Generally jet down, then larger PVCRs. I try to keep them small so the motor doesn't load up when it opens.

I don't know about you, but I don't have ~$360 to waste on tires just to dyno.

A traction problem is not about tires and you WILL wear out slicks extremely fast on a dyno.

Its all about the straps and weight in the back. We have had plenty of cars over 800rwhp on our dyno that didn't wheelspin.

Hope you get the carb worked out.
That motor should make close to 400rwhp on the motor . . .

I didn't say anything about BUYING a set of slicks. I said put a set on.

I don't own a set either, but between my other 3 car buddies I could borrow a set for the day.

And not to poke at Isk but, with a car as fast as his I would own a set of slicks.

at this point, slicks would cause other damage(body,drivetrain etc) so i'll work with street tires and learn to skate
