How much power are you other MS4 guys making?
Alright guys I know the power threads have been done before but I want to see power numbers from people using the MS4 just to see if Im sitting in about the right numbers with mine. I am trying to get an idea of what else I can do or change to mine to get a little more power so add in what heads and headers and remember mine is in stock 346 block so if yours is in a bigger cu. in. block please add that in. Im making 460rwhp/406rwtq

also your intake is a stock unported FAST 90? pacesetters are 1 3/4" right??
what flywheel and stock or underdrive pulley?? etc...
thats damn good #s.... Im hoping to make 20 more rwhp with a similar cam, but in a 402 and a compression ratio of 11:1...
also what rockers are you using??

IDK i've seen ms4s in an M6 put down 410-420rwhp. With that fast 90/90 you should be at around 450rwhp if you are lucky.
If you are at sea level with cool temps, maybe it's not too hard to get 460rwhp. Kinda depends on the dyno.
Either way, good numbers.

My car was done by Tx Spd and it was dynoed on their dynojet. Yes the fast 90 is stock as in not ported and my headers are 13/4 the only other thing I have done is the Tx Spd true duals X-pipe with bullet mufflers and the pulley is a powerbond 25% underdrive pulley, and cant forget I do have the 85 maf also.

I'd say those are pretty decent numbers. Anything else you do (besides n20 & FI) will probably only net you minimal gains. Such as switching to the 92/92 or changing the headers to 1 7/8 or just a better flowing header. Hate to say it but those are almost the exact numbers I got with my ms3.

I do have the dyno graph I just have to find it, we just moved out of west texas and up to northeast tx so ill have to look for it but I will post it up as soon as I find it. Its okay if other cars made almost the same power with the ms3 it doesnt bother me I have seen some cars make about 15 more hp with the ms3 and good heads then what I made but every car is different and so is every dyno so what can ya do. I am just curious what numbers others are making with the ms4, bc I havent seen too many others with the ms4 in a stock 346 most of the time its in a 347,348,or383, and some even put it in the 408.

I have an ms4 with stage 1 prc ls6 heads a 25% underdrive pulley stock ls6 intake with a stock throttle body and 1 3/4" pacesetters with true duals and only put down 430hp and 391tq. Also that was a SD tune as my MAF sensor took a ****

Alright guys I got my dyno scanned and put on the computer but I cant seem to make it small enough to get it posted on here so if you guys can help me figure it out let me know and I will gladly post it.
