haven't done this mod myself but from what i hear and going by the mods you have i don't think you'll see a large gain from a larger throttle body, i'd spend the money else where..got a ripshift?? assuming your cars manual

[VyLS1Berlina]

Will give you a small gain with a bigger TB, any gain is a good gain in my book, will be fitting a 85mm Tb to mine soon, plus a OTR and mafless tune !

The bigger throttlebody won't do a great deal for a stock-ish car. Even on a cammed car the gains are very small. If anything, the best thing about the bigger throttle is much better throttle response. To be honest, for $600+, you could spend the money elsewhere - put it towards new diff gears instead.

If you do go for the throttlebody, then there is no point in going bigger than 78mm on a stock manifold, because the hole in the manifold is only 78mm in diameter.

yeah its manual and i have heard some good things about the rip shift might have to add it to the list hahaha.

but would also have to agree with vyls1berlina that any gain is a good gain.

Don't buy the Ripshift, buy the Billet Specialties shifter - better made, better feel.... wish I had bought one instead of the Ripshift....

mate save the $600 on a bigger t/b, the money would be better spent elsewhere at this point in time. If you want to do something to it DUS ports them out and does a damn good job at it, I did notice a bit more crisp response but by no means have done back to back testing.

Looking at your signature i says you drive a vy clubby. If this is the case then the HSV tb is a great one I wouldn't be changing it in a hurry.

I don't think the VY Clubby came out with the Red annodized HSV TB JB, I could be wrong though............is this the one your referring to?

I found good results with a 80mm power throttle body off ebay.

Was a good product and easy fit and should work well with otr and mafless tune you are planning.

Inlet manifold is only 74mm. Maximum it can be ported to is 76.5mm.

[hsvr8ls1]

thanks for the input guys

but i think i will just go with the otrcai for now as i now see that there isnt much point in upgrading the t/b.

The clubbie hsv range did not come with the 78mm t/b red anodized one.
These t/b only came on the gts models.The holden and hsv clubbie and r8 t/b are the same.

did you have to get a retune after installing the 80mm TB??
