Performance Inlet Manifolds - HOLDEN V8 304

[Immortality]

finally figured out which place was doing the twin TB setup similar to the group A manifold, it's a bolt on job using all you excisting sensors/cables etc, check out there site

Mate the spacer just raises the tb a bit more and gives it a bit more of a tunnel ram effect. Air speed is increased. It's a really cheap power mod, and the harrop works really well with it. The only thing is your tb hangs out the bonnet, so some sort of scoop is nescesery, i havn't worked out wat one to go yet, any one got any ideas wat would look tough on a vr senator?
I'm up for all opinions!!!

sounds gold mate .... im looking @ ten grand for my engine whats the diff form a 30 tho bore to a 40 bore. what compression u running?

I am going 2 start from the bottom end for the 304 what are your recomindations on bearings,blue printing,balancing,decked etc.... + pistons?

Mate not much between them, it was originally 30thou, but the motor was using so much oil, i told the engine builder and the machine shop and it dragged out for 12 months, 20thou km's later the engine was fully rebuilt again, but had to bored another 10thou. I got this all done in adelaide. I'm running around 9-1, i wanted flat tops, but the builder just went ahead and got the machine shop to install the race series hyper dished ones, so go for nothing less, i will either have to shave my heads or change my pistons, not sure wat to do yet. After setting up the new intake i 've passed 10 big ones aswell. The life we live hey.
I recomend going the acl race series bearings, get it all interally ballanced and get your fly wheel matched. And decking and all that should be done by the machine shop without asking, but make sure you do.

Geardys Nice work with the pics and info.


I First seen the Lukey Manifold In October also saw The HSV Twin TBody Brand "HSV 355" Vn Clubsport which put out 230rkw stroker 5L running this Manifold and the Crane Cams 286 camshaft.

Does any one else have info on the Walker manifold,suppliers,website and stats? Does the price incluce the Throttle Body and drilling,does the fuel rails need to be edited ?

 

[sir355]

no idea, but by the looks of the photo, the original fuel rails are used!!

Subdue, here's what yout want. I've mentioned it before but anyways, no other manifold is going to get you down the 1/4 mile faster than this one in a auto 5 liter, it still makes comparable top end hp to the good single planes but the bottom end and midrage is FAR better
