Just wondering what my options where, and if there would be a justified difference in power. I don't care about streetability, or maintenance, I want HP.

Currently I'm running a HSR, cc306, and Protopline 200cc heads on a 350. It put down 355/350 rw power and I was curious to see if the swap would be worth it. Any thoughts?

 

The singleplane intakes are all about power. I just recently went to holleys intake, thats a re-cast of the original cutler design. Its an air-gap intake, and the ports can be ported to a 1206 no problem.

ACCEL's pro-ram is also a decent intake. Kenwood is using one on his car.

I'd stay away from the victor efi. It seems like the cheaper, crappier of the singleplane intakes.

If you measure runner length and width or the volume, you will find that they are similar to the HSR or minirams floating around. So your answer lies in what a HSR or miniram act like.

I am still working on my single plane conversion. I have made three different throttle bodies for the intake before I arrived at the one I liked. I am not going to say anything else on it before I finish it though. I am writing up on it. It looks pretty though.

 

I'm curious as to what you base this on. NO baiting...honest

The victor is simply a Victor Jr with injector bosses I thought.
Which would mean that the VJ is a cheaper crappier intake too.
Which a lot of people would disagree with.

 

Victor EFI isn't based on the victor JR. From edelbrocks website:

" Victor EFI is based on the Victor E manifold #2978. Ideal for high-rpm drag race applications, the Victor E has a larger and deeper plenum than the Victor Jr. #2975. It provides maximum power in the higher rpm range for engines with standard port location iron and aluminum heads. Runners have a tapered cross-section, and plenty of material at the manifold port exit allows port matching to many different heads."


The way the fuel rails are held down is kinda shabby. I don't like it at all.

The port size is small, and cannot from what I understand be ported much larger than a 1205. Edelbrock claims it can be port matched to bigger heads, but everyone I've talked to that has one says there is not enough material to port it.

But of course, this is all just my opinion. When I did my research, I went with the Holley because it appeared to be the better of the manifolds. But thats just me.

So there won't be much difference between the HSR and a single plane EFI?

 

From the track times I have read and the measurements from my old HSR and the single plane I have, yes. It is pretty close. HSR has a huge plenum though, so the induction pulses should be a little smoother. Has anyone done any good tests to see if that makes a difference with a MAP system?

 

Alright then, I guess I'll stick w/ what I have...
