Vy s2 sv8

[sxchsv]

Hey guys I have a S2 VY SV8 with only 89,000kms on the clock, and its Stock as a rock,
Im looking for the Smaller Mods at the moment to unleash it a little over stock standard.
Was thinking a Twin 2.5 System and a Growler Kit...

Could you shoot me some Idea's please

You only need one thread on the subject.
Tune, full system and intake will get you good gains, start there.

Twin 3" Zaust!
and OTR CAI
and Tune the Baby!!

Ok well in response to this thread and your other one.

Dont go 3 inch unless you are certain you are getting big work down the line. You will lose a fair whack of torque. Go twin 2 and a half.

Get a good OTR, the Growler shit you mentioned in the other thread is gay. IMO the best OTR on the market is the DuSpeed OTR. The Ramjet from GM Motorsport isnt bad but it looks fugly and sticks out like a dogs breakfast.

Twin 2 and a half exhaust either Tri Y extractors or 1 3/4 4 into 1's with a good OTR and a mafless tune. Should see you up around 220 rwkw.

as above, piss off that growler shit DuSPeed is one of the most decent looking 1's around head to their website there about $750
and unless your going a big cam or forced induction then go for the twin 3" setup otherwise stick with the twin 2.5''

Hey thanks for the advice Guys,
I certainly wont be doing anything major to the Engine as far as mods are concerned,
So I will be putting a Twin 2.5" System on it, and love the look of the DuSpeed CAI.

Appreciate the help..

This is a myth. I've tested it back to back, as have many others. You don't lose torque from going too big in the catback, you lose torque from going to big in the extractors.

[Grennan]

Fair enough.

I imagine a 3 incher will drone pretty badly though one a otherwise standard LS1, correct? Sound pretty mean though.

depends my x force twin 2.5 droned more than a manta and difilippo twin 3

DUDE! you gota stop posting BS!!!!
i can tell you when i changed mine from 2.5 to 3". it felt way more responsive and could tell it had more balls down low then before! (before i had the twin 3, it use to have twin 2.5)

also only x-force twin 3 will drone. mine doesnt drone at all.
Diffilippo all the way mate

My x force twin 3" didnt drone, but was loud as hell!

[Sphinx]

I run twin 3s and it doesn't drone at all.

[cpbait]

you got much done to yours sphinx? i think last time i spoke to you you had a mild cam, did you have heads done too?

[Sphinx]

nah, no heads yet. cash is being funnelled towards a procharger at the moment.

[cpbait]

oh ok nice, cheap from the states at the moment.

My ute - L98, Isky cam, Tri-y's, 2.5" twin xforce - 325.5RWKW 687NM
Friend's ute - L98, Same Isky cam, 1 7/8 extractors, 3" KPM - 329.7RWKW 703NM

Looking at the charts mine has more torque down low - his peak power figure is less than 2% higher than mine - Maybe the 3" is a wee bit of overkill for a 5.7L with a standard cam, considering ours are 6L's and there's next to no gain in it for us?
