wilson manifolds carb spacer question - 07/19/10 07:49 PM

anyone tried or use a wilson manifolds 1" tapered carb spacer as sold at summit and what results did you get, just want to know if it is worth spending $120 if I wont see any results, I currently run just an open 1" phenolic spacer, thanks for any input!

I had that very spacer a few years ago, nice piece, but it didnt do anything for me.

that said, every combo is different, you probably know that spacer might make a bit more torque, compared to your open that might help up top more, just depends on what you are looking for.

It was a very nice piece, sold it at Norwalk to somebody several years ago.

I have no idea about Wilson spacer but here is piece what has been dyno and track proven and really works : http://4secondsflat.com/carburetor_spacers.htm

i'm not sure about the wilson unit. i recently bought one of these penolic tapered spacers. it's a lot cheaper than the others. i wanted something to isolate the carb from the manifold & this fitted the bill plus it looked like it might do more than just be an isolator.

Most of these spacers work with your camshaft design. overlap, etc. To help velocity & mixture.

I like those, I wonder if they would have any positive benefits on a tunnel ram setup...??????

I have used a Wilson version one time it didnt help
out for what I wanted... I have found that if you need
the velocity the standard 4 hole works fine(low end
torque) if you need the plenum volume the standard
open works fine(top end HP) and no need for the fancy
trick stuff.... JMO

I run one on a 408 with a victor 340 open plenum single plane. Kinda splitin hairs, but it looks like it improved my 60 foots by about .007 when I averaged a few of time slips.

expensive yes,do they work yes me and ryan j put my 1" 4 hole spacer on and no bs 15hp on the dyno,also woke up my more mild 418 better 60ft 1.47 off the foot..its a nice spacer

Thanks

Ryan,
I meant the green one that is posted. Wondering if putting the taper in the plenum will make a difference?

Sorry for the confusion, have not seen that design for sale, but yes they almost always make "some" difference. I have never put a tapered Spacer, whether it be an HVH or a Wilson on motor on dyno & not have it do SOMETHING positive.. gains like 15HP are rare. Normally you see 4-6 TQ/HP. Maybe 8-10 sometimes....

How about an air pan....

Ryan have you run a (we will say) a standard 4 hole
then run a tapered in a back to back on the dyno,
I'm sure it might be the added velocity in either
to get a better TQ/HP ... at least thats what I seen
when I was doing headers on the dyno but we played
with some spacer also but you have more dyno time
than I do
