na vs supercharger

BlackOutBoxing · Jul 1, 2014

My last 99 gen2 was a heads and crazy cam car 620rwhp! It did 131 mph in the 1/4 mile. Anyone know if a 99 with just a paxton, headers, cat back without cats can match that? Im sure boost makes a difference so lets say with 10 psi. Always did heads and cam cars. Never a supercharger. Can forged Iinternals handle 10 psi safley?

It's likely you would want to run **** injection at that boost level (with a proper fuel system). Talk to Todd at A&C Performance -- he has a lot of experience with Paxton cars and NA cars with upwards of 650 RWHP.

Good luck with your build!

Yes to both questions. So many variables like fuel system,tuning platform,boost amount, and track conditions that will affect performance, but you'll be able to match the numbers you had with the H/C car.

Nice! Thanks for the info!

IMO, the most fun you can have is a built motor/paxton car.

Plum speaks the truth. Why pick head/cam OR a blower? Do it all! That's what I did. Best decision I've ever made.

Most people say an na car with less horsepower can beat paxton car with more horsepower in the 1/4 mile. If they have the same hp the heads and cam shouldalways win

A very wise man told me that

maybe the low end is that much better in na.. Built paxron motor is totally opposite of built na. Compression, cam . etc.. Plum did u ever 1/4 ur car? What mph if ya did? Johnny same question for u if u raced it.

Are you planning on doing more standing still quarter mile races or highway pulls?

BlackOutBoxing · Jul 10, 2014

Yea that's what I guess it comes down to. How much faster is the Paxton from a 60mph roll? Ill go to the strip often it's open wed and fri nights as well as sat and sun. My last na car was fast from a roll. It would walk 750 street bikes but never got to see it against a Paxton viper? How bad would it be do u think or know

JohnnyBravo · Jul 10, 2014

My car went 9.8 @ 144 on pump gas. The car makes a fair amount more power now than it did on that pass. And I'm not the most aggressive driver, either.

I think that was only a 1.51 60'. I still run 100% stock suspension, stock half shafts, etc. No power shifting.

I think the car has a 9.6 in it with the new setup, still on pump gas.

Nice time !!!! Congrats. What's the rwhp on that thing? Incredible!

plumcrazy · Jul 12, 2014

bOb, id be willing to bet there is no NA car on the planet that could have beaten my built motor paxton on rt 287 regardless of how many times we ran

BlackOutBoxing · Jul 12, 2014

How bout in the 1/4 Plum? Bet a stroked na car could beat it there no? U never ran in the 1/4?

I'd be your huckleberry if we crossed paths.

All NA motor.

That night it was around 920 rwhp or so. That's what the dyno showed on a cool motor for that setup, but I'd made a pass or two and the air temps weren't as good. But somewhere in the 880-900 rwhp range is probably accurate.

The car now makes a little over 1000 rwhp and 987 tq. I need to get back to the track with the new setup and see how it does.

Darth Menace · Sep 29, 2014

is that 920HP on a built motor with a Roe?

plumcrazy · Sep 29, 2014

no, he has a paxton

Darth Menace · Sep 29, 2014

That's still amazing. I thought that could only be done with a TT kit. Shows what I know. Now I have to study up paxton vs roe

There is a Roe SC for sale on Ebay. They don't come up for sale much.

I've got a Roe on my Viper running 5lbs. of boost and 3.55 at the rear and this is what I know about them so far: super snappy, fun, and good looking at car shows. I get a lot of compliments. But it ain't gonna win any races against a built engine with a Paxton and I'm already jonesing for more power.

mattdillon · Sep 29, 2014

Blackout, i see the 131 mph but what kind of times are you turning?

BlackOutBoxing · Sep 29, 2014

I dont have that car anymore. I turned 11.1 with a 1.996 60 foot time. It was 32 degrees out. Next time I ran I only got one run in, I had 1.6 60 foot time but missed 3rd. I was told that one 10th saved on the 60 foot time is two 10ths off your ET. If true that car was a mid 10 second car.
