Default Well got my dyno #s

Not super stoked at what it made but not totally disapointed either. Just was hoping for a bit more. Car is set up for spray and I have 300rwhp shot at the push of a button. Guess we will see how it does at the track.

Car made 403/350rwhp/tq NA in 85* weather and kept making power to 7300 on the stock pcm.
Set up is 383 with a 244/254 610/610 110lsa LE nitrous cam and LE2 heads, single plane with Nitrous Outlet elbow. Has a A3 w/ 4500+ non lock up nitrous stall, also when dynoed it had the tru trac and 4.10gears. It now has a 3.54 and light weight spool. So the numbers arent totally correct. The spool is way way lighter than the tru track like 15lbs vs 40+ lbs so It woulda picked up a few rwhp there im sure.
Im also not sure if the single plane helped or hurt. I know the ports are not 100% correct ie. intake ports are bigger than the head ports. Not sure if a stock intake would be better. Might test it some day.

Anyways it is what it is and now need to make it to the track.

Holy **** the tru trac weighed 58lbs with the ring gear still attached and spool had a 15lb shipping weight in the box. Wonder what thats worth in the 1/4 and rwhp?

My two favorite things to say:
Numbers don't mean jack if it can't get down the track.
I'd rather be a track king than a dyno queen.

Hope you have fun with it at the track.

Yea, don't worry about numbers too much, see what it does at the track, The stall is contributing to the low numbers also, Heck Tony S na numbers were not as we expected, but with the spray, it really woke up. Like my car, It was built for forced induction, NA it only made like 383 RWHP and with boost, it made 648 RWHP...

Ya Im not too disapointed with it. Just kinda sucks making less na on the dyno with the
A3 383 vs the t56 355. But the motor is def making more power for sure.
The only compairable set up is 94Zrag's but his is a 396 with a bigger cam. He made like 430/380

Don't sweat the low dyno numbers. Big stalled auto's aren't ever going to show good on a chassis dyno. I'm sure it will move out just fine dude.

Pretty good #'s for a non-lockup converter considering most people who post their A4 dyno #'s lock them,

When I had my car dyno'd (540 BBC, TH400 with 3000 stall) the #'s were about 50hp off or more based on mph at the track and the weight of the car. Couldn't hook for crap on DR's.

Last month I made 358hp ~2000rpm short of where it should hp peak. Two years ago I made 420hp with 1 full point less compression, smaller cam, and the t56 at the same rpm lol. Should run pretty strong with those numbers

I new I saw the bird down the street yesterday! I wouldn't sweat the numbers. I have plenty of faith it'll give a bunch of suckers the tail light view. BTW, she's even more beautiful in person. Lol

Gotta get the suspension dialed in but I can see this doing it with your combo.

Don't you have a build thread?
