Still a lot left in her - hit the rev limiter in 1st, shifting soft the rest of the way as the RAM adjustable master is not up to the task (tick here I come).

Hopefully kooks and a mufflex + shift light + tick master + diet for car = 130mph
Need to get an aftermarket rear before install the LPE launch controller and nitrous

Looks like he has got an LME built 416. Looks like that thing has some good top end power.

Once you can get it out of the hole that will be a low 10sec ride, Nice!

It can be done, I ran 10.29 @ 129 with my old 408 N/A and that motor was originally built for nitrous. You get that 60' down and a good clean pass and you'll be well in the
10's for sure.

nice pass

Mufflex and diet in the same sentence is funny just put a cutout on the current Magnaflow and be done.

i am with larry on that one my mufflex sounds so good but 75lbs come on thats almost a tenth lol plus i read into what larry said about my mufflex holding me back and its true most guys with the mufflex gain 2 to 3mph with a cut out or a bullet right off the y just my .02

Thanks guys. I currently have a single cutout on the magnaflow. I'm thinking it's the pacesetters that are really holding me back. On the dyno, I only picked up 5 rwhp from 5700-6400 (with the cutout open).
I'm thinking 1 7/8" stepped to 2" Kooks, with 3.5" collectors, y pipe into single 4" through a bullet muffler dumped at the axel? The tunnel mount TA limits a descent true dual setup

congrats on the pass and like you said you defiantly have a lot on the table ....60ft,headers and exhaust will have you in the 10's

good luck

FWIW, when I had the 408 I went from 1 3/4" headers to 1 7/8" and gained absolutely Zero on the dyno and the track. That was N/A though, with nitrous I'm sure it will help.

I'd leave the headers alone until you have at least 20-25 more passes on the combo. I doubt bigger headers would be worth more than than a tenth on motor. On the hose they might help but again I'm not sure it will be dramatic.

Are you running on street tires or something? What does the car weigh, like 4K? Great MPH but ****, get that pig on a diet.

99TransAmLS16Spd

iTrader: (8)

I'm running on a ten bolt...hence the weak '60 times.

Not sure what the car weighs, i've put it on a bit of a diet so far - BMR k member/a-arms, weld skinnies op front, weld 15x10 w/ et streets in the rear, !a/c, !ABS, !cruise, and a lot of other basic stuff.

My goal is to keep the interior looking stock in terms of weight, but I can still manage to shed some lbs with rear drag brakes, bumper supports, etc.

MPH is good, would have been better if I had my shift light hooked or the factory tach was worth a damn, hitting the rev limiter in 1st, then short shifting the other 2 shifts def didnt help.

I may try to get more runs in before swapping headers, but I do think these Pacesetters are holding me back. Dyno showed only a 5hp gain from 5700-6400, which tells me the weak point is either in the exhaust or possibly intake.
