With a XE 224/330 on a 112 LSA can I get 350 and 375 at the wheels?

Other mods will be Hooker coated LTs and not sure of exhaust setup yet. duals maybe.

Can I make that with stock heads? maybe with a XE 230/236?

Or would ported stock heads be needed? or at least make it easier?

What other mods will I need besides the 1/6RRs, springs, rods, etc.

 

Using the 224/230 it would be really had to make that kind of power with stock heads. Anythings possible tho.

With ported heads you could easily make that kind of power, thowing in the 230/236 will make even better numbers.

I think Atljar made around 350 on stock heads with the GM847.

 

rumair hit 348 with the cc305 a long time back.

Stock heads only flow so much, you don't need to go overboard on the cam. The right combo, good tune, all your ducks in a row.. you might get it. I don't know about the 375 tq, but 350 rwhp can and has been done on the stock castings/M6 (which you obviously have). I'd be in the 340's if I had the M6 vice A4, for instance. Throw on a cutout and who knows!

 

Why would the 375 tq be harder to reach?

I dynoed stock with 256 and 289 at the wheels.


SO 230/236 and proted heads and a good tune and I should be able to do it?

 

You should easily be able to hit 350.

 

with heads definatey.. I don't know if u have stock heads. I have a friend that got 333 with the cc305 with stock heads

 

At least one guy (Frank95z I think) here has dynoed @ ~330 with a 210/224 and stock heads. Madwolf did 348 RWHP with a 233/239, also on stock heads. Both cars were A4's. If your an M6, I'd think you could be right in the hunt with a good tune.
