I have a friend who's wondering what you guys think he will dyno. Here are his mods. Of course all this is Based on a good tune. I figured anywhere from 440-460 rwhp. What do you guys think?


Hooker Ceramic coated Longtubes w/ ory

Cut-out

.232-.234 w/ .646-.613 on a 111 lsa

Fast 90/90

Patriot Stage 2 243 casting heads w/ Patriot Gold Duals spring, titanium retainers, seat etc etc etc 64cc chambers.

Powerbond 25% UDP

SLP Lid

Ported Descreen 85mm MAF

All free mods

F.A.S.T. 42lb injectors

Stock 4l60e w/ SMI Built 4000 Stall w/ 2.5 STR w/ Hayden 29k cool cooler

160 T-Stat

3.23 gears

Ported LS6 Oil pump (not that it matters)

LS2 timing chain (not that it matters)

 

I'll say 435 RWHP. What do I get if I win?

 

The thought of knowing you won lol

I'd say 440-450 would be about right.

 

Almost the same set-up as me.

If he already has LT headers and an exhaust I'll say 425 rwhp. If not, I'll say 400.

 

Darn, I was hoping for a prize

 

auto...big stall...

i'll say 435.5rwhp

 

is this before or after the tranny explodes?

 

Before! there are quite a few guys I know who have auto's with no fast intake pushing 420-430... I would think at least 450 but I might be off on this one. Whoever is closer gets a prize.. What the prize is only time will tell!

 

If you don't mind me asking, what did you put down? Nice setup BTW! 11 second club? low 11s?

 

What kind of dyno is it?

 

Most likely a Dyno dynamics,

 

i would say about 420rwp

 

i say 439 rwhp!

 

hmm. through a stalled auto. if it were M6 i'd give it 450-460. that's one reason i don't like dynos. lol auto guys always lose in HP battles. oh well it's all about how they move i guess.

 

425...

 

Wow my auto with just lid, lt's, 85mm maf, ported tb put down 329. I would think the cam is worth at least 50 along with the heads would be at least 50 and the fast about 20? Thats pretty crazy all that stuff is only going to gain him 80 more to the ground.

 

^^ That was with a stock verter?

My setup put down 419 on a dynojet......

 

No one said anything about a stock converter.... A stall isn't going to add any power..

 

424rwhp 385tq with a locked converter.
Unlocked 395hp

 

Wow. I hope you're being sarcastic because stalls effect dynographs a lot...
