12.6196 @ 110.76 1/4

Daily driver with only mods in sig. run on 93 Chevron w/ tune from Triangle Speed Shop

All seats and in, only removed spare and jack, 275/50/17's M&H DR's on stockers.

Ill have video up as soon as I can, as well as scan slip.

Ran a 12.65 @ 110 about 8 minutes later.

Nut'n great, but Im happy.

I have stage II Livernois heads on there way as I send this...

Ill dyno as well as run with JUST THE HEADS and a tune (of course) and post as well.

Ive seen adding cams add hp and not too much et; after 50000 miles , I want a 'safe' upgrade to keep running, so Im going with the heads ( and avoiding spring headache ).

I do all my work myself, so I'd be lieing if I said I wasn't going to port match.

Ill post as soon as I get (hopefully good ) news.

Cheers
 
Comp cams has come out with a new series of cams for the 4.6 3 valve. They use a phase limiter to work with the cvt so we won't loose lowend or mid range. They come in 3 stages for FI motors and 3 stages for N/A motors. Thaave made as much as 80 hp. JDM Engineering made 401 RWHP on a 298 stroker using these cams and the car still passed emissions testing to be street legal. You won't need to take off your CMCV plates to run these cams as there made to work with that system. Finally a set of hot cams that won't rob the lowend torque. The 3 stages are from mild to wild, if I'm not misstaken, I believe stage 1 doesn't requie new springs, I don't remember for sure. If you have any questions, you could E-mail JDM Engineering or comp cams. I believe a set of those cams and you could be a 12 flat if not high 11's. At anyrate, it sounds like you have a handle on it, awesome job!!!!
 
Thanks, but Im going to see what the heads alone do on dyno and et first for 3 reasons.

(1) curious as to what the heads do by themselves

(2) wished someone else would have tried this and posted, so I guess Ill take that chance (As I appreciate those who 'cammed' and honestly posted before me) and pass on pratical knowledge.

(3) heads come complete with Livernois springs, so the cam change later will not be a problem.
 
chad9350, nice run!!!

Curious about the dyno #'s in your signature. If I'm reading correctly, there's more than 30rwhp and 30rwtq difference between a Dynojet and Mustang Dyno. I know the Mustang Dyno's read lower than the Dynojet, but that's a big difference!

I ask because I just had my '07 GT automatic dyno'd on a Mustang Dyno last week and it put down 351 rwhp. I was really expecting around 375 rwhp, but am still happy with 351 rwhp. The dyno operator said the Dynojet would likely only read about 10-15 rwhp more. Your thoughts?
