I have an offy and weiand 4bbl intake. I need to sell some parts to get my truck going. I am trying to decide which manifold might be better to use,and I am going to sell the other.

My observations:

The offy has a larger plenum area.
The weiand is slightly taller and the runners are slightly bigger.

Everything seems about the same. I had planned on running the weiand,and selling the offy...but I like the looks of the offy's plenum....I am curious to see if you guys think there might be an advantage to one or the other before I sell one of them.


For my 87 D100 Eddy 500,hooker LT headers,HEI,and 4.56's stock engine otherwise.

I do realize that if there is a diff. it will be very small,and will prob. not be noticeable in my application.

Decided to stick with the Weiand

If I had both I would use the Weiand just because there is less of them out there.

That is exactly what swayed my decision. Even if im loosing out on a small% of hp/tq,its worth it for the coolness factor to me.

Ditch both of them and buy a short runner AussieSpeed!

I can find MANY ways to better spend 500.00. I have already owned a LR Hurricane and I was not impressed. The cliffy outperformed it in every aspect.Plus the old Weiand is wayyyy cooler than the aussie intakes.

o.k.

raPoM,

I also picked up an old Weiand intake manifold for the SL6. I had it bead blasted and ceramic coated with a clear sealer. It will go on my updated "Torque and Mileage" block. I am hoping that the Weiand runners will provide better mixing and produce better low end torque over a Clifford or Offy.

We will have to compare notes later this summer.
Your truck build verses my car build.

I have only seen one Weiand live and in person, and it was on a race car. Seemed to work fine as far as I could tell.

Not seeing much real world love for the Hurricane stuff.

Ted-

You know it buddy! Stan (hyper_pak) also has one,though im not sure if he plans on using it in the near future or not.

My(hurricane) manifold had some pretty major core shift going on,and after replacing my clifford with it and spending a few weeks tuning it, I had had enough and sold it to a member here. It just did not seem to live up to the claims that AS makes.The clifford had it beat on low-mid-and top end.... I was very disappointed,especailly after shelling out 500 bux for it

Some Weiand/Eddy eye candy:

only used an offy on the street and racing with everything from a 390cfm up to a 750dp cfm, runners are closer in length and bigger plenum + 2" spacer. have no complaints;no comparision either.

It looks like the Hurricane has more equal length runners.

Do the Clifford and Offy have distribution issues like a stock intake?


I would really like to see dyno results.

I sold my Offy because a 2bbl is all I need for now. I want to go turbo on the Duster hopefully EFI.
