want more power out of vt ss

[vpcommo]

i just bought a vt ss and it only puts out 170kw at the wheels, was wondering what i should do to get more power out of it

check my signature mate.

Maybe all the usuals: High ratio roller rockers, CAI, Sports exhaust with extractors, High ratio diff, tried them yet?

Is it a Holden 5ltr, or a Chev LS1 engine you are running?..

For a 5ltr I would recommend the following.

- Aunger CAI
- K&N Panel Filter
- MACE Throtle Body
- Performance Headers (i.e XForce)
- XForce Racing Cats
- XForce exhaust (Cats back).

A good tune, some good leads and plugs will go that extra little bit before you get in to seriously expencive engine work.

exhaust and maffless diff gears-should get you into 12's if thats fast enough for you

If it's putting out 170 at the wheels it must allready have a fair bit of bolt on work, you wont get much more out of it (if it's a 5 litre)

That depends of course on whether or not thats a "real" 170rwkw tested on a Dyno, or Holden's claimed figure for that engine (which was actually 180rwkw if my memory serves me correctly).

There is an artical somewhere website where someone got a VT 5ltr to around 190rwkw with just bolt ons and a tune. I cant remember where I saw it though.

helps to know which motor

since when do manufacturers give out their engines power outputs in rwkw? also, theres no chev ls1, but thats another argument altogether

yeah im thinkin the same he said 170rwkw which is about right for a stock vt ls1

Right you are, after double checking it's 180kw(ish) @ the crank / flywheel.

and you got me on the Chev bit too... *Admits defeat*

[vpcommo]

yeah its the 5ltr, its already got a 2 1/2 inch exhaust with extractors but thats all thats done to it and it has been dyno'd at 168rwkw

[Not_An_Abba_Fan]

Best bang for buck mod after what you already have is a tune. Greenfoam is the man you need.

u got the dyno results by any chance?

[taztassio]

throw the 5L in the bin and get a super 6.

yella terra make a bolt on m90 kit for the 5L give them a call

throw the 5L in the bin and get a super 6.

I thought he wanted to get more power, and not go backwards
