Not trying to hi jack the thread mike but I got another question..

Weiand tunnel ram with the top removed will accept a 4500 flange what are the pro's and con's to running it set up this way??

Takes a ton more carb if no plenum is there. Might work on a below 400 inch deal

You're going to need a plenum.

What size is your engine?

What type of car?

I have ran the Weiand on a 466. The 750's were a little more consistent ET wise and weather changes didn't affect them as much as a pair of 1050 Dominators.

Dyno wise the Dominator's might make a tick more power. Track wise in my old Mustang the 750's and the 1050's ran almost the same ET wise. The 1050's had a little more MPH, about 1 1/2 MPH. These are just my results though.

Not many rum them, choosing to stay with a single carb. If you are bracket racing the ET doesn't have to be the fastest only the most consistent.

You'd have an I.R. manifold at that point and fuel stand off at the booster.

I'll use J.Y. Kell's 562" P51 engine as an example....it's been four years since it was done and a few things have changed but , I feel it is a valid example.

There was 17 more HP at the two manifold's peak power rpm in favor of the 'mafia' thing. The fully ported victor manifolds [w/o welding etc.] seem to hit a rpm number and immediately fall off.

Randy's engine with the 'mafia':
950.6 HP @ 6,700 rpm
950.6 HP @ 6,800 rpm
951.3 HP @ 6,900 rpm
950.7 HP @ 7,000 rpm

That's .7 Hp from 6,700 rpm to 7,000 rpm...seems the engine is hanging on to it's power.



I have two regrets....
1] The engine was not pulled to 7,200 rpm with the 'mafia thing'.
2] I did not get a copy of the dyno sheet for the best pull with the ported Victor.

Bottom line is that @ 7,000 rpm the ported victor had went back to the house and was down a lot more than 17 hp.


Yep, it's the same kind of deal with this engine.....the "Mafia" holds on to the power longer than a Victor.

1017 HP @ 6,600 rpm
1018 HP @ 7,100 rpm

Lem do you have any feed back regards to what the 17 HP is worth ET wise vs the Victor.

I agree it is application driven.

Gary, 17 HP is 17 HP,  who knows what E.T. difference it would make..............  In perfect back to back  runs it is what it is.

The deal is that, It makes more power in every test I have seen done, some more some maybe 2 hp less on engines that can test the boundary of the intakes. This isn't peak number either, it's across the usable rpm range.

Lem is just showing one more thing that adds HP to the engine we all love.  Not sales, not horn blowing, just concrete facts.

The Mafia generally peaks about 300 rpm higher than a Victor and brings that hp with it. It moves the tq peak up by that much too.

Spacers to get the booster or venturie above the standoff ......... Same as a multiple carb bike engine.

Lem I understand what you are saying. You have explained the dyno test's of several engines before.

I just want to see what the ET difference is. Like you say it's application specific.

Thanks for that dyno sheet.

Ok Gary here is what you want to hear........... Nothing, zero, zilch, probably unperceivable at the track.

So that must mean the Mafia was a waste of time and effort and the Victor is the time honored king of intakes.

Probably best to even go back to the Weiand tunnel ram. But only if you run the A429s with it. There is nothing to compare to them, they all run within .05 of a second.

Up yours Gary Blair  what have you done and I mean in this century, not back in the 70's.  today is a different Story I bet you built a Rochester 2 bbl 283 that made 1000 hp too  with a set of twice humped heads huh?

Thanks for that dyno sheet.

Here is the way I see it:
If an engine has more power between peak tq and 300 -400 rpm past peak HP it ain't the engine's fault that it does not run faster.

I agree, in the quest for more hp/tq more is more. in order to see an et improvement a few variables must be met imo, if the car/driveline is less efficient than the engine all is lost, slippage of mechanical parts or maximum traction is exceeded it will likely slow down not due to lack of power but the sum of the total package. an extra 17 hp on my pit bike would be hard to control, 17 hp more on a car that black tracks will be wasted.

None of that matters, we are racing dynos here, if you can't make the extra HP work that is a personal problem. Razz
