Has anybody used this intake on an LT1? I wanted to do a single plane set up and stumbled across this manifold and it looked interesting. Not a bad deal if it actually works, eliminates the need for an intake elbow so it really might be cheaper.


Gonna do the 24x LS computer conversion and try to push 8k.

 

That's a dual-plane manifold...if you're going to spin 8k (what are you running exactly?), then you'll want to stick with the single plane.

 

isn't that like an efi box style manifold?

 

Yeah, but technically (IMO) it still uses the same principles of a dual-plane manifold.

 

Noone uses it because there are better alternatives.

 

it's not a dual plane design, all runners use a common plenum. i'm just curious why the OP thinks the elimination of an elbow makes it a cheaper alternative? Usually when you're looking to build a motor that makes good power at 8000 rpm, cheaper alternatives are left out of the picture.

 

Why do you need to spin it to 8000? Is it a 283?

 

no he must have watched that red Ai car spinning to 8k on the dyno

 

make a 331 and spin it to 10K......thats fun, just doesn't sound right coming from an sbc

 

8k?
I just wanna make people wonder what's going on in that old LT1.
Also, the cam i'm gonna use is just a shade smaller than the GM847 which just starts to kick in at high RPM. (maybe won't actually get 8k but i wanna use all of that cam). i just feel really limited by the 7200 limits of the LT1 PCM and I don't wanna go 383

this is what I was wanting to know. not looking to spend all my dollars on an intake elbow and manifold etc. if I can do the same thing with one manifold.

I'm sure there are some drawbacks to the proflo although I'm still curious if it's capable of supporting that rpm range with the 90mm TB

maybe I should ask the sbc crowd it may be more common on gen I sb

 

you're in way over your head based on your last post. a super vic will have better distribution and make more power than that pro-flo manifold. neither are necessary at the rpm level you'll be turning with a gm 847 sized cam.

 

You need to do ALOT more homework.

 

bingo, i'm a long way from actually buying stuff yet. just wanted to know if the proflo was equivalent to a single plane, apparently not. i've just never heard anything good or bad about it.

I wanna do the single plane, elbow, and 90mm with the LSX pcm. You have some experience with this yes?

Reason for mods:
I have a buddy putting an LQ9 6.0 in his M6 T/A with L92 heads and intake etc. I'd really like to beat him with my 355 LT1.

 

good luck
