Default Accel Prototype elbow

Thought I would share something I was recently able to purchase. I know some of you are into things like this.

Wonder how many pieces were casted that never made it to production or took off like that back in the day?

Cool find! Oddball stuff

They put some serious time into making this. Welded all the way around on inside but edges are rounded on outside.

Even the throttle bracket appears to be one off. Its tiny compared to the one on my Super Ram and on old TPI. With LPE/Accel 58 MM TB bolted up linkage all lines up perfect. Now just need to find a single plane EFI intake and play around....

Very interesting indeed. I've never seen that one before. I assume a prototype?

Any test results?

The guy I purchased it from was a former Accel employee. He said he was able to snag it one day they were cleaning house and throwing things like this away!

Cool stuff,i remember a guy here made a similar thing modding a stock TPI plenum.He welded the runners ports and opened the base, welding on an intake flange.

edit: find it...

I haven't seen any shop throw out anything aluminum in years.Stuff cost to much and usually ends up in a aluminum trash pile to be sold off to the recyclers. You got lucky.nice piece.

if you remember guys,there was a custom intake made by Callaway in the early B2k conversion.It was a TPI intake without runners,basically the same as previous pic. A plenum welded over a single plane intake...Making an elbow out of a stock TPI plenum is a piece of cake,instead of lot of welding on a prototype,i would take this way...

That was a "TPT" looking intake (plenum) cast as one piece with short-mid length runners. Very much like a shorter runner HSR, or a tall plenum version of a Miniram.

I'd love to find a Callaway 100+ intake, McFarland Short Ram or even a T-Ram.

I know there are "better" intakes, but to me, the T-Ram is FBA. Different, good looking, OEM quality, I love the thing and would love to have one too. I passed on a complete T-Ram set up 10 years ago...I thought $1500 was too much. I thought wrong.

Some one took a lot of time and effort to make all that stuff. Hope you can find the parts you need to get it running.

If he can space the prototype plenum/adapter high enough for the TBI T-Stat housing to fit under there without it being so high that the plenum/adapter hits the hood - then he's good to go...

Otherwise he'll need to block the opening off (Moroso makes a plate to do this) and use a remote T-Stat housing plumbed to the (2) 1/2" NTP pipe ports on each side of the Intake water passage....

The miniram Tstat housing is pretty small.
