My new short block should be done in a few weeks. cant wait to see what this engine is going to be like.

LS2 block
All ARP studs
TFS 225 cnc heads
LS6 intake for now thinking of finding a FAST 102 to feed this pig later
Diamound Pistons CR 8.5/1 just like the last engine
Callies 4inch dragon slayer crank
howard rods

new cam sorry dont have the spec on hand

need to send my PY3600 out and get it tighten up to 3400

so hoping to get to Milan before the year is up. ill let you guys know how it works out . hoping to pick up 100rwhp over the last set up which would put us at 790rwhp on pump gas at 16psi. but we will see

Sounds good man.

That extra 100 hp would sure be nice man. What exhaust are you running on your setup?

thanks

tomz28 09-18-2011 05:26 PM

those 80lb injectors are not going to be happy when i go to 20psi on race gas

My guess would be atleast in the mid 700 @ 16psi, and mid to upper 800 rwhp @ 20psi. on mustang dyno. I won't be surprise to see 1000rwhp @ 21-22psi on a dynojet.

You need to ditch that muffler. Thats a decent restrictive muffler on a h/c ls1 let alone a boosted car.

its 4inchs and open how could it be restrictive

Nitroused383 09-21-2011 03:38 PM

Is it the mufflex spintech muffler? There have been results posted over the years of it being restrictive on a N/A car. 14 hp / 19 ftlbs of torque on a cam only LS6 car vs open cutout https://ls1tech.com/forums/12206934-post41.html

Fbodyjunkie06 09-21-2011 03:59 PM

I really need to get rid of my 2OTL exhaust. I love the sleeper look, but it's just got to be restricting me at least 30-40rwhp going from my dynomax muffler thats 3" inlet to two 2.5" outlets. If I were to just dump the 3" over the axle and face it out the back at a slight angle and let it just run through my dynomax bullet that's in the 3" i-pipe after the 3.5" dp necks down. Should sound good too.

Your's being 4" I don't see it being too bad, but it could be worth some ponies.

Yes it is a better flowing muffler. I have the same one on my car and just ran a 9.58. You should be in the 9.50 range with your setup no problem.

Ehh, I don't have 200 plus right now for the e-cutout I'd want and the welding, cutout etc.

15 bucks for a 3" turndown and 5 bucks to weld it on works good for me, and I'd like to make it a little louder actually.
