can this thing really add horsepower? or is it just a waste of money
can it be used with an all new setup?

im just tryin to find cheap things that i can ask santa for xmas

 

If you are going to get it for free then why not, but i wouldnt really spend any money one it.

 

^What he said.

 

ask santa for a summit gift card so you can hang on to it and then add a bit of your money and get something good

 

Well, I wouldn't do it if you plan to upgrade your throttle body. I'm not certain, but I suspect that they are 65mm and work best with stock TB.

 

no, why would any increase in length of a tube of laminar flow increase 'power'? although the spacer is not stopping flow, it is still creating more wall to air friction which in turn doesnt help or hurt much. IMO its just a gimmick that people use to try and immitate what tunnel ram manifolds on carbed engines can do. remember you want the shortest possible travel for the air to get into the engine.

 

That could be debatable. Since the TB spacer is installed "in between the intake and TB", you've effectively increased the plenum length of the manifold, which also acts as a longer intake "runner", which is good for low speed velocity, increasing low-end torque. It could be a trade-off, low-end torque vs. high horsepower, but in this case, probably not enough to notice where in the total powerband the difference in torque peak or max RPM HP occurred, unless you have a chassis dyno.

I'd say a TB spacer is good mod for more low-end torque, just make sure and get the right size that matches the size of your TB entry so there aren't any interuptions in airflow. [sm=goodidea.gif]

wow 83gt thats the first good thing ive heard about a TB spacer i was going to get one a long time ago cuz it was jus sumthin i came across that said added sum power but ive heard TOOOO many people say they are a waste so no TB spacer for me

 

Okay...let me re-state that a bit. I guess the dude asking in the first place is running a 4.6 in a 2001 Stang, and I'm referring to what might work with a carbed or EFI 5.0.
I'm really not very familiar with the modular Ford engine (4.6-5.4), but it seems that the basic principles would apply to "any" engine. Summit racing sells a "Trick Flow" 3/4" raised aluminum intake plenum for the 4.6 that's suppose to add an additional 100 cfm of airflow for more HP, but does anyone make an aftermarket "intake" for the 4.6 yet? Don't know that.
On 5.0s, a long runner intake is good for velocity and low-end "torque", and a short runner intake is good for mid and upper rpm "HP".
Same as in carbureted form...dual plane intake for street, single plane for racing.
I keep hearing everyone say "horsepower", but is that what they really mean? "Horsepower" is a function of "torque", but only is useable at high rpms. "Torque" is the "seat of the pants" power that you feel when you mash the go pedal from a standstill.
I think if these late model Mustangs are mostly street driven, then the driver would be more happy with mods that enhance "torque" than "horsepower". But horsepower can be gained through any mod that enhances torque also, cam change, intake & head porting, free flowing exhaust, etc...
It seems like the best power adders available currently for the late models are just superchargers, intake enhancements, and exhaust.
So, in light of that being said, BUY A SUPERCHARGER, I think that's all you can find for a late model. Best bang for the buck! ($3,500 of 'em)

 

83gt got a point^
