yeah according to PA they said the less rotating is what increased the peak rpm. Now it is time for the real test, a ET slip :D

I did the C4 swap and nothing else beside a retune. Everything else was the same. Old 4R70W combo: DirtyDog Performance 4000rpm stall Converter (reworked PI converter) 282rwhp and 304TQ (locked converter) New PA C4: DirtyDog Performance 5000rpm stall 8" converter 280rwhp and 367tq (no...

I finally got 1.59 60ft but it was hot so I did not run a new best. I ran 11.96 with the DA being 3060ft. I ran two 1.59 then my posi went out. Time for a spool :D

get some sticky tires :nice:

No power adder and race weight was 3065lbs. The aluminum block shed some weight for me. The car dyno 291rwhp and 320TQ

gotta love those VT Stage II cams :nice:

Waiting for a new TB to come in so we can dyno tune the car but here is video of it before tuning: http://videos.streetfire.net/video/2829c119-32c2-473f-baf8-98ef01487139.htm

Here is a quick video of the car running without a tune. The video really does not do the sound justice, it sounds killer. http://videos.streetfire.net/video/2829c119-32c2-473f-baf8-98ef01487139.htm

motor is together and we are going to drop it into the car tomorrow. Everything went smoothly. The motor turns over freely which is a good think.

Thanks, I ran 12.4's last year, so I'm hoping for high 11's with the new combo.

Car getting tuned this weekend so pics and video will be posted then :D

I bought a 98 4V motor that I sold the 4V heads and few other items and just kept the shortblock. So I now have a lighter Teskid aluminum block for my future build. With lighter aluminum block with 2cc dish pistons my CR will be 11.75-12:1. The heads were Stage I ported and 1mm larger Crower...

check modular depot, this site will not let me post a link from MD for some reason.

already has, check modular depot, here the quote "I just found out from the shop that tunes my car that an employee just installed a 324 high compression motor in his and it made 417rwhp but can't remember the tq. Under his sig it says "fastest 2v na in the country." Said he's running low 10s...

Who is running high compression NA motors? Mine is 12:1 with VT Stage II cams. The heads are mildly ported with oversize valves. Just wondering what to expect rwhp with high cr motors. Thanks

I have a 98 4V that I bought to do the 2V to 4V swap. But after reading I'm a little concern about a couple of things and wonder what your opinion would be on this issue. Remember this is a 98% drag car and I'm staying NA. On the 2V: Forged rotating assembly, 9:1 CR, & 262AH cams made 272rwhp...

my combo was Mac LT, MAC O/R H-Pipe and Bassani Catback. Here the sound clip: http://media.putfile.com/02-Exhaust
