X1 cam and 383 dyno 446 rwhp
447 rwtq
MTI said I should change the Led and see about 8 rwhp more!
But the TQ is very nice!

Re: X1 cam and 383 dyno Not to bad for a mild setup. That cam is actually somewhat small in the bigger motors. Some GTP ported LS6 heads and a bigger cam would put you up about 20-25 rwhp. What compression are you running?
When you said "led" do you mean air lid?

Re: X1 cam and 383 dyno so you're not running a cut-out, ported TB, or ported MAF/Ends either?? What about !cats??
if so those are amazing numbers, nice numbers anyway!!!

Re: X1 cam and 383 dyno He is running a stroker not an all bore. The all bores will make more power due to the 4.1+ bore vs 3.905 for the stroker.
I think the numbers are great and that cam is very mild for that package.
If you do not have a lid on the car you will get another 20+RWHP no problem.
If I were throwing a 4.0-4.125 stroker crank in my car I would go 236/230 112LSA .60x lift minimum reverse split.
Great numbers!

Re: X1 cam and 383 dyno WOW, nice numbers with the mods and a stock air lid!!!
And NO CUT OUT!!!! that would probably add about 10+rwhp!!
I think you could easily be sitting at 470+RWHP.
Curious why you are running a stock MAF (with the screen too??) I believe LS1 edit should solve any issues with that.

Re: X1 cam and 383 dyno Ok, I wanted a daily driver with no drivability issues at all. The car idle very good with no stall problems at all. In fact, if it had the cats on, it will be hard to notice the cam.
The bottom graph (412 rwhp and 404 rwtq) the car was not running very good. the max we were able to get from it was 412 rwhp with 6 dyno tunings.
The mods were:
*No cats
*2.5" y-pipe
*FLP headers
*226.5/226.5 114 LSA
*K&N FIPK
*LS6 intake
*ARE heads (they did not flow very well, because they had 2.1x intake valves and I ordered 2.08 <img border="0" title="" alt="[Mad]" src="gr_images/icons/mad.gif" /> )
*Stock MAF
*ASP pulley
*MTI tuning
*ATR cat-back
*SLP 4 tips in the middle thing! (Probably lost 4 rwhp).
Ok, the middle graph (439 rwhp and 435 rwtq) This is after the installing the X1 cam. Also, MTI changed the valves to 2.08 and stock lengths and 7.400 pushrods. ARE use some weird valves lengths which makes the pushrods 7.250 long (very short).
The mods were:
*As above +
*3" y-pipe
*X1 cam
The top graph (446 rwhp and 447 rwhp)
After tuning we got this result!
We did not spend much time on tuning. I think there is about 5-10 rwhp more if I played with LS1-edit a bit more. I could probably install a batter MAF, Put the whisper lid style air induction on (as been told by MTI, the Whisper lid style lids will have better power (about 5 rwhp more) than the FIPK).
*As above +
*Tuning
There you have it!!
I am very happy with the car. It picks up like a bullet!
Yeah, and get this, when I left MTI a ricer Civic pulls next to me a start riving his engine!
What can you say! I was hungry and my SS was too! Therefore we had some rice! <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
