nightstalker, thanks

I just finished a 99 RT/10 that came to me with no cats, smooth tubes, and K&N filters. The car has 15,000 miles on it. I installed the Roe Supercharger with a 7 pound pulley and an MSD fuel pump booster. It has stock rockers and stock manifolds with Borla exhaust. So it is pretty close to stock. First dyno run was 594.5 torque and 555.2 horsepower. It will make more with some tuning. I will post the numbers for you after I do that; which will be tomorrow.

What kind of times could the above 99 RT/10 turn in the 1/4 mile on street tires?

not even answering on a "possible" value?? I'm curious too!

Okay, Okay, the car has a stock gear, so considering good driver, good conditions, and a respectable 60 foot time, I will go say low 11's. I have been 11.5 with a 2.0 60 foot with similar power but less torque in a normally aspirated car.

I'm just curious as to what a basically stock Roe car will run without headers, headwork, T&D's etc., but with the 7 (or is it 8) pound pulley.

Final numbers are in: 639.5 torque and 595.6 horsepower. FYI

david, are those digits RWHP?

Yes, with a smoothing setting of 3, S.A.E. correction factor on a Dynojet 248. Hey, Mojo, I still owe you something! You still need it? I have been so busy with the move to the new facilities that I over looked it.

I drove Ldy Nightstalker's at TWS this weekend and it was niiiiice. Amazingly tractable power and it stayed cool through the entire run. Temperature was something I was rather worried about but it stayed right about 200 degrees the whole time.

I did notice some flat spots in the power band in the 2500 rpm (I think) range. Not a big deal at the track where you're winding it out pretty much all of the time.

I'm running the new VEC2.2 with new programmed computer cards for it and it is absolutely amazing. There will no longer be any flat spots anywhere in the RPM curve. Sean Roe is perfecting an already great product. I'm one of the few people with the VEC2.2 right now and I can tell you that it is a big improvement over the VEC2.1.

Nice improvement in power from just a little tuning! Nice numbers! What did you do to get the extra hp?

Sean Roe's software program is awesome. A little here, a little there, and a HUGE thanks to Sean for taking the time to teach it to me.

Were you using the new VEC2.2?

This was a 2.1, I have the hardware/software coming to make them 2.2's.
