Performance Inlet Manifolds - HOLDEN V8 304

[Boost Junky]

Some people have made 200 *just* with the banana but not many have and that's about as far as you go. 170-180 is easily done, you can do that even on stock compression and a well selected cam and good exhaust. But the other 20 doesn't come easy

appreciate yr coments m8

i'm gonna throw on a 70mm TB, upgrade the twin exhaust to twin 3'', then talk to u about purchasing one of yr memcal's

cheers

guys

what max rpm's do most guys shift gears at, with stock or mild modded 304 EFI's?

 

[greenfoam]

Anywhere between 5200- 5400 on a stock motor with a good exhaust give similar times, up to about 6000 with a cam suited to the banana manifold

my combo peaks at 6200rpm, so if I want the best out of it I shift around 6000rpm

this is my first post! im looking at manifolds at the moment because i am upgrading to a bigger cam.

can anybody recommend a cam for me with the following specs of my car?
i have a vr 5l auto with pacemaker extracters, twin exhaust no cats, 3.9gears in the diff with a mini spool, standard stally.

and im looking at an active manifold with a come racing throttle body. i will try and attach a picture of this manifold.
any help would be much appreciated!
i might add that this car is gonna be for doing skids mostly not for street.

cheers

Anyone been given a hard time by the law with the COME racing twin throttle body manifold?

Would love to get one of these for my car but have heard that cars have been defected with this on. Only other option I can think of is the Star Performance one.

Mate you can be defected for any change to the engine that you make that isn't standard, only way to be safe is to have your mods engineered if your worried/ if possible. But in short if you put a come ttb on you can be defected.

Interested to know whether anyone (2enil8 may have some experience) has tried a hi-rise TP dual plane, but with an elbow and ls1 t/body, instead of the carby-look 1000cfm???

I now have a VN Grp A scoop on the VP and understand that the hi-rise d/p will probably suit my 355 222deg combo. Thinking of adding a spacer (1 or 2 inch) open or 4-port, and then an elbow to an ls1 t/body.
Then into an airbox arrangement.

Has made 239rwkw thru custom ttb manifold and t5 - and makes 189rwkw thru bananas, a 3800 conv TH700 and 3.45 IRS. Awesome torque, but know there's more to be found with a manifold swap!
