throttle body spacer

[burnoutking]

Who has experience using throttle body spacers on a 360 magnum? I've been told by a few guys that they gained nothing. Anyone?? What sort of gains should a person expect on a stock 1999 360 magnum, only change being straightpiped and throttle body spacer to start with. What are other good bang for the buck mods. ie: performance chip, headers, larger throttle body, etc. Any input would be appreciated.

everyone says they are useless. makes a good paperweight though:jester:

I heard they are fairly effective wheel chocks, but that's about it.

So is there any particular reason they don't seem to do anything on a magnum. What are good external mods to start with, I really don't plan on doing anything to this engine internally except maybe cam swap in the future. I have a 410 in an older 4x4 that I play with.

I've also heard a regular old air cleaner does wonders on these engines ?????

TB spacers are junk on a EFI motor.

If you plan on doing a cam...You better be prepared to do...

Springs
Rockers
Pushrods

The list goes on.

Okay thats why.

As far as the cam it wouldn't be a big cam anyways. More of a torque cam. I was looking at a couple in the 210 @ .050 dur. and .460 ish lift.

tb spacers are:bs: Go with a f&b throttle body

all my tb spacer does is make a cool whistle:jester:

They help some on carbs and throttle body injection, direct port fuel injection systems where fuel is sprayed in the intake runner right before entering the cyl head.

[burnoutking]

duhhh. I guess all I had to do was look at my engine and see that the fuel is being injected into the runners so yes a spacer would have no effect as the air /fuel mixture is after the fact. I guess the little good a spacer might do would be that it may improve air velocity coming through. all I was really hoping for was some possible torque and fuel economy.

[AmberFireDaK]

It won't even do that..... cause of the design of the intake runners, and increase in velocity or any "swirling" effect will be lost by the time it gets to the cylinder
