Dynamometer Results & Comparisons - MS3 Dyno Numbers

Mods in sig below. Keep in mind I am having an issue right now with my 4500 stall not locking up, this run was no lockup on the converter what so ever, according to the guys at the shop (Speed Inc) if the converter would lock add another 35-45 RWHP because of the size of the stall. Considering I can pull my friends 387 RWHP H/C LS1 I believe it.
Condintions-82.94*F
Humidity 29%
SAE 1.05
RWHP 363.10
RWTQ 322.47
Peak numbers for HP was @ 6750 RPM where the dyno stopped and were still going up not more then 10less HP from 5000 RPM up.

Peak RWTQ was at 5400

If these numbers would have been on a locked converter I would have been pretty PO'd but like they said if the converter was locked I'm looking at a 400RWHP A4 with an LS6 Intake no FAST and a stock TB and Stock Pullys.
Also I picked up a new Walbro 255 because the engine kept leaning out time for a better pump. Also running TR6 plugs gapped small because im getting ready to try the spray on this cam.

Don't worry about numbers through an auto with a stall like that. Take it to the track and you'll get a better Idea of what you're putting down. Like you said....by pulling on your friend you are obviously making more power. Just make sure the tune is spot on and have fun.

Yeah that is a big stall. You are probably right on the numbers. Good job.

Those are really good numbers. You should run mid 11s all day long & in good air hit some low 11s

With a PT4400 I did 388 RWHP & ran 7.43 @ 92 mph. Then added a Elec Waterpump & Pully & did 7.26 @ 94 mph.

I pridict 7.50s all day cause you have a N/A converter. You should be able to cut some high to mid 1.5 60fts

Looks good! :thumb:

I'm thinking about doing a FAST 90/90 intake setup and the stg 2.5 5.3 heads over the winter also a pully and a little bit of a diet for the car anyone thinks 10's on motor is possible?

I think it is very possbile with that converter if you stay N/A & keep your converter. You should be at a solid 420 RWHP easy with a FAST90/90 & 5.3 Heads & the bump in compression & then taking out weight. YEAH 10s are in your future for sure buddy:D

If it were me and I was taking the time/money/energy to do heads I would mill 'em down to get compression back up and flycut the pistons. Should be screaming with that, and you'd get some tq back.

Converters chew up tons
My ms3 did 388rwph unlocked and 429rwhp locked
with a 4000 stall. Glad you have 3:73s.
Your car should scream.

Thanks for the imput guys Ill put up the results when I do the heads.

i have the ms3,ported ls6 heads,ls6 intake, tci 3800 stall, 4.10 gears. Dynoed 408/378 then after somemore porting, underdrive pulley and cooler air it hit 425/390.

Fuck the dyno numbers with a stall like that, run that bitch at the track I bet it hauls ass.

I'm thinking its doin alright, the other night I ran my buddies car, at the same dyno his car dynoed 395RWHP and like 38X RWTQ, (LOCKED converter) hiis car is 40 lbs lighter race weight and from 40mph to 100 I put about 3-4 cars on him. cant wait to get some track with this new stall and some other mods I did. I'm doing stg 2.5 5.3L heads from TSP and a FAST 90/90 this winther with an UD Pully hoping for 450RWHP Locked.

3-4 cars is a beating from 40-100

Keep in mind, you lost some on the gears, but not much
