aussie intake

[mdiesel]

got my holden intake from austrailia today. cant wait to get started on this build now

[LETZRIDE]

What are the plans? I had one and never had the opportunity to get to using it. I would love to see a few more builds with these!

It looks cool - but the US stock version is actually better - so don't expect some crazy performance gains.

I thought I had read and understood their manifold actually flows a little better?

I don't see how the us version is better. the long neck inlet of the f-body intake is a major choke point and the air distribution is terrible. the aussie version not only has better distribution but the intake runners are longer and the bell mouths at the top of the runners are better shaped for air velocity.

full engine rebuild, stage 2 intense heads, custom grind cam 210/216@.05, 512 lift, 110 lsa. assuie manifold. lq4 maf. 36lb injectors. hp tuners. already have headers and straight through exhaust ( no cat). monster tranny rebuild. 3600 stall. 3:73 rear gears.

Bench tests proved otherwise.

Do you have a link to the bench tests Robert? I am curious for the read and comparison

I'm still going with the aussie manifold. The f-body intake has slightly higher overall flow numbers . Shorter runners means more high end air flow. But there's not much you can do to it. To port the bell mouths and polish the plenum interior I would have to cut the top of the plenum off, do the porting and weld the top back on. Then I'd still be stuck with the stock plenum volume which is grossly undersized .
the stock aussie version has slightly higher air velocity, probably due to the longer runners. But more importantly it is super easy to port and polish every bit of the interior. And for as much as I can cut the cars cowl, I can add spacers under the plenum top and significantly increase plenum volume if I wanted to.

For uniqueness, I say go for it.

Sounds like a fun build, let us know how it goes.

I just updated my build thread over at a certain all-but-dead V6 forum and was thinking to myself, "Hey, does anybody even do builds on these cars anymore? Should I bother modifying my engine?"

It's nice to come on over and see this thread and another where the owners have big plans for their F-bodies. I haven't seen a Holden Intake install in ages. Good luck with the build and please keep us posted!

Yea, at one point I thought about getting an older model, but I've owned this car since I bought it new in 2000. I figure, technically it'll be a classic on 6 years, the body is in perfect condition, and I can build the 6 as a ballsy lil street car for allot less money than starting a whole new project, or switching this to a v8 platform. Next big step is to pull the motor/tranny from the car, dismantle it and check the cylinder bores to figure what engine shop work needs to get done. Now I just gotta find the time to do it...

You should make a build thread here and give some of the newbs coming around some fresh ideas!

I am excited for this aussie intake build. I like seeing these and to me they have more potential even if they may flow less than our stock heads as it is much easier to build an upper.

Before I went through the trouble of getting this intake, I had several lengthy email conversations with Keith Abbot of abbot racing heads. He did mention that in a stock comparison of the f-body intake vs the aussie one, ours did win in overall airflow. But the flow bench doesn't tell you jack about the benefits of the improved air velocity and distribution of the aussie intake and how that improves throttle response. When you add in the factor of potential upgrades and ease of porting, the aussie intake was an easy decision for my build. That and I got a great deal on it, only $235 for the whole set up, including the shipping from Australia.
