First off here is my list of mods:

All the freebies from LS1 and LS1tech.com
SLP air lid w/K & N
SLP 85mm MAF
SLP smooth Bellows (waste of money btw)
Hooker Cat-back
Flow-tech Cutout
3.73 gears
TCI Super Street fighter 3500 stall 2.5:1
B & M Tranny Cooler
ASP Underdrive pulley
BMR Lower Control Arms
LS1 Edit + Dyno Tuned

My last dyno was 308rwhp but was before the cutout and underdrive pulley. I have no idea what I am putting down but assuming close to 315 to 320ish.

Now with that said. What will I gain from Pacesetter Long tubes, off road Y and LS6 intake manifold? Will this bring me close to 350rwhp, maybe a hair over?

Then with that said, Texas Speed's Magic Stick v3 cam on stock heads?


Just curious on what I need to plan next. 400rwhp is my overall goal, running NA.

Definatly long tubes next. They will be your greatest gain yet.

I second that

I third that. But don't buy Pacesetter headers unless you're broke. You get what you pay for, invest in a better set of headers like Hooker or FLP (NOT SLP).

I thought about the Hookers but from what I read the pacesetters are just as good performance wise. Durability is in question though. If it'll last me a couple of years then I'm fine with that.

Headers it is, next

I 4th that, I bought PaceSetters and they are excellent quality. The are the best and most affordable header you will find. I have the older set and they are great and I have heard the new kind are great but don't go with thier Y-pipe. Do Duals. Good Luck.. Make the choice do stainless or coated.

5th that? how about the edelbrocks????

I have seen pictures of Pace setters where the welds extrude into the tube. (interrupted flow) I disagree that they are great headers. I run Jet hots which are a less expensive and thicker version of the Hookers.

LS6 Intake, headers, Nice Cam, 400rwhp Easily obtainable!

Headers

even with headers, it looks like u r definitely gonna need at least a heavy cam....or a mild cam with some stage 2 heads to get to 400 to the rear

That's what I was thinking too

On a mustang dyno I'm pulling about 315 at the wheels. Maybe alittle more on a good day.

LS6 intake probably net 8 to 10 right?
Headers, worse case 20hp but I keep hearing people gaining 26 to 34 at the wheels with long tubes and or-y.



With the LS6 intake and headers I should be right at 350 to the wheels if I am estimating everything correctly. Even with a pretty aggressive cam, I am skeptical that I will net 50 more wheel hp out of it. Stage II heads and a decent cam probably so.

Why I am kind of confused on the Texas Speed Magic Stick v3 test they did. Full bolt on Z28 with a 224/224 cam dynoed 360ish at the wheels, then with the new cam, 402 at the wheels. hmmm. That's the cam I was thinking about going to is the Magic Stick v3.

I was debating either a TR224/224 or the Magic Stick

m_donze

Those are hardly comparable.

big difference in both cams!!! what made u narrow it down to these two? youre gonna have some hellified tuning issues with that cam...especially since youre an A4 id go with a milder cam and throw some nice heads on there....maybe a stage II head/224 cam combo might work well for u. u might even hit 415 with some good tuning. good luck bro

The cam my performance shop recommend me was 242/246, .602/.612, LSA 113

They have already properly tuned this cam on a LS1 with A4 tranny.


I know 224/224 doesn't compete but this was the cam I originally wanted. I compared because that was in the Z28 Texas speed tested, then they removed it for the magic stick and pulled 402 out of an A4 car.

blue2000Z28

i have an a4 and that is a BIG cam for us im im not mastaking?? Anybody correct me if im wrong but your gonna need a big converter and some gears...T-rex recomends 410s and 4400 stall and that has 610-612 lift so you might need something around there...ANYBODY correct me if im wrong.

Raise

iTrader: (31)

from what ive been researching for the past few months....if u go with a big cam like that on stock heads, your peak numbers are definitely gonna skyrocket, but where the power really matters is under the curve and i think u might wanna consider that before u go diving into your internals. do a search for dyno result sheets from people who have cammed only cars and head and cammed cars...and u will see the difference. id say if u dont wanna be much over 400, if any, id get a mild cam and go ahead and do the heads at the same time.

THAT IS HUGE. Any clearance issues?

Raben

iTrader: (5)

Na no clearance issues at all. Had to replace springs to Comp 921s and forgot what type of pushrods and retainers were needed. I don't want to chance going with that cam as I am alittle skeptical, not about the clearance so much if they are sure of it, however I am concern about the beating the engine would take

A head swap sounds like a good plan too. From what I can tell, I probably could get away with a stage II 5.3L heads and a TR224/224 cam and achieve that.


Dang just can't make up my mind
