Carb spacer open or four hole .Anybody have any luck at the track with them took my driver to the track the other day now I`m looking to cut that extra tenth or two.Thanks
i use a 1" spacer. sorry i didn't put it on there by itself so i don't know what the difference was. if i go this weekend i'm gonna stick a 2" on there to see what that does. if not this w/e then next.
Have run all size's and really can't say there is any significant changes with my setup. Some heat transfer may help with the phenolic or even wood one's. Also if you are having some low end torque problems like tire spinning, a taller one may soften it up a bit and give a little top end performance. All depends on lot's of other stuff involved, some say ramming the air down the runners is one advantage of spacers. I don't think any thickness of them will get you anywhere near a tenth, but you never can say never in performance parts and mod's to engines. There is a certain point of power adders, that we all attain, that seems to limit just how much more money and things it will take to gain just one hundreth of a second or less. But that is what is great about being a gearhead, the challenge is always there to go faster and faster. P.S. and also to spend more of that green stuff too.:bananaman
Funny how I ask alot of guys at the track and at shows abuot them and the answer I get is, I just put it on from the beginning. I never tried to see if it made a difference or not ,specpecially in the faster cars. And my car has a little traction problem of the line thats what I`m trying to help.Thanks for all your input
I havn't tried one yet...goin to T&T friday night...I've got a couple laying around, might give it a try.
Wilson Manifolds, 4-hole tapered spacer!! Independent dyno testing has shown an average of 20+ horsepower gain!! Or so they say!!
I have tried with and without on my 408w. Didnt notice anything. Just about every dyno test in every magazine that shows a windsor at 496hp then uses a spacer to push into the 500's. I would amagin on a 302 the gains would probably be less
the open will make it act more like a single plane manifold and the four hole will keep it more like a multi plane. many people use an open one on their manifold as a cheap way to turn it into a single plane. not as effective as buying the right manifold, but moves you in that direction. if you want to keep dual plane or multi plane handling, use the multi port.
well... saw this on ebay. cheaper than the super trick spacers might give it a try http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1,1&item=8067934641&sspagename=STRK%3AMEWA%3AIT
I used a 2" spacer on my Performer dual plane, and it really did respond more single-plane-ishly. That is the reason I now go single plane. It felt like it had a better response, and I think I picked up a tenth or a little more on the 1/8th. I was going to use it on my Torker 289, but it already has an extra tall mouth and there was no way I could get the hood to close, or even get the throttle cable to reach it without some serious modification. It held the throttle almost fully open when I hooked it up, so I never started it, and sold it off. I also used multiple gaskets between the spacer and carb, and spacer and manifold, just to slow down heat transfer.
i have a 4 hole 2" plastic spacer... when i first got the engine done.. i had the spacer on with out a hood.. and it had amazing throttle response.. when i put the hood on, i thought the spacer wouldnt fit so i took it off... and i noticed that it bogged a lot.. i put the space back on.. and i swear by it.. they work great. as far as open bore and a 4 hole.. i have been told that the 4 hole is best.. thats why i got one..
