So far this is what I've been doing...











The idea is to make the plenum bigger...

01steve

make sure you have enough room for the fuel rail!

mine was a tight fit.



are you N/A or boosted?

mcorrales

Nice work... F/I over here...

01steve

thanks-... i'm whoring those pics today-...

forced induction intake manifolds are sooo much easier to do than it would be if it was NA. good luck!

mcorrales

Give me your suggestions?

01steve

i'm not 100% familiar w/ what works best w/ turbos-... from what i undertand big plenum, short runners is the better option for boost.

but i'm sure it depends on a ton of other variables.

turbo elements tim did something very similar and his set-up is pushing 400hp (i think).

find some quality time and do a TON of research on the net-...

Thanks... what i've heard is short runners for n/a. My idea is to work only with the plenum, maybe some p&p for the runners...

01steve

it's going to be tough to get the runner elbows polished-...

Read Maximum Boost (Corky Bell)!! He goes into a lot of detail about IM designs, including runner size and plenum length. I also have a full writeup (someone's senior paper) on exact testing and specifications for it all (including Helmholtz resonance). But yes, in general, short runners for FI, long ones for NA.

From the book: Chapter 6, pag 78.

" An intake plenum should be several times larger than a cylinder's displacement "

That gives me an idea...
