Interesting...seems like it would work good for big cubes & high rpm. What do you guys think?

 

Short side on that elbow is a killer.

But could you make it work with out alot of pressure drop?.

 

best part about that is its built for a TPI head wont do no good on a LT with out other work to make it bolt up.......


might as well just call bret tell him your plans and let him do a conversion for you

 

LPE/Accel make an elbow just like that ready to go. Ive posted on it before if you search my name plus accel elbow

 

I have seen those Vette boys take a carb intake and bolt a "box" onto the carb mount with bolts that go all the way through, and bolted a throttlebody on the front.....ran 10's on motor if memory serves.

Thought I'd help out.

 

More then one is in the 10's with Jebs old intake I think the newone wil be even better. The reason for him making the intake and the reason it is short is the fact it was made to be used in a C4 with the stock hood. We have limited clearance and all of the after market intakes other then mini-ram and SR wont clear.

I'm thinking that it can't be much better/worse than any of the other elbows or elbow type plenums out there.

 

How much does the intake and conversion cost? Also when should one need or look into getting one?

 

I compleatly agree unless you have a C4 corvette. The hoods on these cars are big $$$ and most don't want to hack a hole in the hood so that is the real atvantage of Jeb's setup. There are plenty of single plan intakes out there with the elbow that will work on most cars just not the C4.

 

Is the reason for an elbow like this just because of hood clearance?

 

Well it could be worse but I'm not exactly sure what the effect would be. My thinking is probably in line with Bret's when he mentions the short side radius. My intuition says it should be as large as possible for a gentle transition into the main plenum but what do I know. Never tested it one way or the other.

sseeya,

Yep, it's all about hood clearance.

I figured it must be, because there are several aftermarket companies that make 1000+ CFM, 4 barrel throttle bodies that bolt right up to a single plane intake manifold. Holley, Accel, and Ron's Fuel Injection are three that come to mind.

 

Funny I still cant find one of these elbows from Holley, Accel or Rons. I've seen a picture of the Accel one and it seems to have the same problem as this sheet metal one.
