turbotater

i am going from this


to this

turbotater

with my old intake i did 320+ rwhp but it was falling
off in power after about 5000 rpm i cut it up some
more but it still didn't increase useable rpm range
so i am going to try this set i made. i really would like
peak power @ 5500>5600 and not fall off hard till 6000
might know in a week or so

are my eyes deceiving me or is that a dual plane intake?... should go with single plane for EFI

turbotater

yes,this is a large runner dual plane manifold.
is it your opinion that having fuel injection changes
the requirement for intake manifold design ??

Like it, something a little different bet it works great with the DP once tuned not to mention great midrange torque!

scamaro355

Well since its not a "wet" design like a carb with the fuel flowing through everything. Usually a straight shot into the intake runner is alot better since your just moving air. Do some research on it, i'm not saying it wont work... you just never see a dual plane EFI setup for certain reasons

turbotater

the reason i questioned was when i played
with 5.0 mustangs alot no matter what size
the engine was the rpm range still was
determined partly by the intake design .
if i installed a victor style intake i would
loose low rpm and gain high rpm .
just like going from a tpi style to the stealth ram
softens the bottom power a little but increases
the top greatly especially with a stock or similar
torque converter.

i will find out soon enough

scamaro355

well the swap between tpi to stealth ram is due to runner length... but i wish ya luck keep my posted on how it does

looks good. Should pull to where you need it to, but how hogged out were the runners on that tpi? Were they siamesed a good ways in?

I would expect a good ported base and siamesed setup to peak in the 5500 range.

turbotater

the runners started out as the originals to the car . i sliced them their full length and merged them together with sheet metal creating 4 oval shaped runners ,i ovaled the plenum to match the runner and then shaped the inlet to the base for minimal turbulance. this was part of the 320+ rwhp setup. i tried to get it to rev higher so
i opened up the base to the point the opening in the base was larger than outside of
the runner mounting flange .so i added material to the flange and siamesed into the
base about an inch or so and tried that. i may have gained a little power but did not
dyno it like this. it did not however extend the powerband like i desired so next....

i am guessing that it being a 383 with kinda undersized heads makes it a little more inntake sensitive

turbotater

i put my old intake up for sale

i have it partially installed now

Looks awesome!

Who made the intake elbow?

turbotater

i made the elbow
this setup just clears the hood. it hits the padding a little
but i wanted the biggest radius on the short side of the
90 i could get for best airflow/distribution.
I just have to finish the fuel and vacuum connections and
then put therories to the test

later

Great job on that. I wish someone mass produced something like that. Only found one place that could custom make elbows for TPI throttlebodys. Everyone else makes LSx style elbows and is what I got stuck with

Lingenfeter was making a elbow like that back in the 90s. not any more.
iv been looking at a set up sorta ike that on the Victr Intake made for EFI.
