[N/A-PWR]

Hello all,

 

I was just checking out different 9 port inlet manifolds and now realize,

 

that the new 12 port Aussie-speed inlet manifold may suit my set-up well:-

what do you all think, is the 12 port manifold too big?

Don't tell me you're putting a 4 barrel on it Dave?!?

[N/A-PWR]

No, the 2bbl works fine Jonesy,

 

if there were a need to go better, then that is later. 

 

 

Don't tell me you're putting a 4 barrel on it Dave?!?

500 to 730cfm 2bbl

500 should be plenty

Be nice if Aussie-speed made a 12 port manifold like oldjonno's manifold:-

otherwise, will have to make an adapter plate to turn the 4412 holley 90° for the 4 bbl manifold.

You can't fit 3x2" SU's on that thing.:(

Hello Warren,

 

How much does a good set cost?

 

You can't fit 3x2" SU's on that thing.:(

Do you mean triple holleys?

 

Why not weld another 2 350 mounts on each manifold runner.

Wow, Gold in the making, I wonder who did well with them Jon? 

Yep, I've done it before.

Regards

Amazing Jon,

 

One day with the Strombergs the back one backfired blew the air cleaner off, it went a long way up in the air, looked back through the revision mirror and the air cleaner landed on the bonnet of a taxi.

 

I had a Fan blade shear off on the X2 HR, and that shot threw the bonnet, never to be found.

 

 

Here is a Triple carburetor adapter for a 4BBL manifold:-

I'm with you Dave, I don't see why anybody would bother.

OK for information purposes,

 

 just did a rough measurement of the 186 wilkie stage 5 head of mine,

 

No's. 1 & 2 inlet port, with the face size being 61x43mm, and feeds the two inlet valve size's of 1.625".

 

The port has had the boss removed and replaced with a bolt sleeve.

 

 

The picture shows water as the medium, as 1 gram of water = 1 cc,

 

 and used a 100 gram measuring scale twice to get the whole port size measured,

 

 which came to 182.3 grams = 182.3 cc:-

Have you ever had this head flowed Dave? Mine is almost identical to yours. 186 head, touch over 100 thou off (no witness mark left) same valve and port size. Mine is in the car tho so I cant test it as you have. Mine flowed 187 cfm at .050".

[N/A-PWR]

Hi Adam,

 

have not ever had a flow test done,

 

 will be very interesting to see if she flows well.

 

Yours has a decent amount,

 

 and how does your engine perform?

 

 as @ 0.050 is where the exhaust is still scavaging?

[N/A-PWR]

I think you ment 187cfm @ 0.500" lift.

[I'm a Red Motor fiend]

Yes mate, 0.500 not 0.050. Thats my dyslexia lol, got my jords wumbled. Really happy with my tune and performance at the moment. Head is on a 208, 11.3 comp, Waggot 104, triple 1.75 SU's. Very snappy, very responsive. Will light the tyres in third and keeps the big ass V8 commodore taxis honest.

[N/A-PWR]

Great, thank's for the info Adam,

 

 yeah, mine could go on any used short motor,

 

 wack a 30/70 - 41/78 cam in it, hurricane tuned extractors and a 500 holley,

 

 and she would light up 7500rpm all day, and would wear the big ends out after 2000 miles or so.  

and hi Adam ( skap )

Mine did 13's at 105 mph in 3rd

[I'm a Red Motor fiend]

Never had it down the quarter. I just enjoy playing with them and cruising on weekends when I can.
