HI guys I'm swapping an ls6 crate motor into my car within the next month or two and was wondering what is a good prediction for a dyno number? Motor is basically brand new with only 5k on it... mods are as follows
BBK LT'S
ORY
3" Mac catback
Tune
MTI lid
MSD wires (not good for really anything lol)
Alum. DS from a 3.23 geared car
Ported and Polished T/B
ATI underdrive pulley
I was hoping for around 380 on a dyno jet seeing as I've seen m6's go from 390-400 without the underdrive and some other little things...Anyone else think its possible

I would guess 350-360 RWHP on an LS6 through an auto. What rear is this going through?

stock 10 bolt and stock stall for now a buddy of mine just did the same swap and with a lid/catback put down 356 on an a4 I realize all dynos read differently though so we'll see I'm hoping for a bit more than that seeing as now my ls1 threw down 340 with the above bolt ons and I watched several m6 fbodys put down around 400 without an underdrive pulley or ported tb and z06's usually through down around 385-390 with the irs. stock they are usually 350-360 I know thats an m6 but still lol, this is going on a dynojet also

No offense man but did you read that it is a full ls6 crate motor swap and not just a ls6 intake on an ls1 motor. I mean full bolt on a4's will dyno around 340 with a tune. There was a guy locally who just did the swap and used his 155k stock shortblock and made 360 without and udp or throttle body so I'd think there would be more left in there more even so since it was high mileage. I realize if I was gonna dispute every post I shoudlnt have made the thread but the posting do seem a little low seeing as m6 cars will make around 400 in fbodys with 10 bolts.

My crate ls6 did 413 rwhp but it's a m6 threw 4.10's

Thats more like I was hoping for only one way to find out for sure though
Thats really stout for an ls6 crate and at the time you only had the mods in your sig? I'm not expecting to be close to that because your an m6 after all but 380 i'd be happy lol

Pretty much....and a ported ls6 intake and a oe throttle body that I bored out. It could need a little more tuning after that. A 3.5" catback I made too.
