throttle body spacer??

[surfmoto23]

where can i find one for an 07?? or can i just use a an 06 05 or something??

 

[triumphrider-1]

Just say no.

Can you say waste of time and money?

Seriously, don't bother.

the helix throttlebody spacers are a waste, they supposedly spin the air etc, when in reality all they do is make noise and restrict airflow. if you want to put a spacer in the engine for more power id consider a phenolic spacer between the upper and lower plenums, this makes the intake runners a lil longer and pull harder, increasing torque. read up on them at rogueperformance.com.

i would not suggest one , except in certain applications , i have a buddy with a 95 K1500 Chevy , it has a mild built 355 , msd ignition , holley throttle body , edelbrock intake , tube headers , the works , he is running about 11:1 or 11.5:1 compression , his truck would actually not run right till he put the spacer in , but that is not a stock motor , let alone a v6 , so in your application , there is no purpose

on that 355 was the spacer he installed a heated carburetor spacer that preheated the fuel to aid combustion? thats really the only purpose of a spacer for that type of deal and increase runner length to make it pull harder and get more fuel. a fuel injected engine doesnt really see much benefit from such just a few more torque numbers down low. the carb 355 needed the extra suction to pull the correct amount of fuel to the engine, w/o the spacer the engine ran lean, hence he needed it. the amount of work done to the engine had a lot to do in playing that he needed the piece. a stock 3.0 does not, unless of course you stroked the 3.0 n/a motor w/ a fair amount of porting etc and a cam...

Sorry to dissapoint You Rurouni, but He mentioned HOLLEY THROTTLE BODY so please don't confuse any more the subject. The throttle body spacer DOES have a reasone for its existance. Central Throttle bodies or Tuned Bowl Injection system and Carburated Engines have the same method of mixing the fuel and air. So they DO recquire the spacers in order to help produce the necesary air turbulence to help in the mixing. As for Direct Port Injected engines find this spacer render usless due to the fact that (Dee dee dee) the injectors are directly on the entrance of each cylynder. Therefor (if any) in this kinds of engines (if it was possible) the "swirl" type spacer would help only if they could be instaled right after each injector. There TRS Fabricators... Follow up on MY IDEA.

pardon me i misread on the throttlebody, and your right about carb engines needing the swirl, but efi engines of course do not. putting a swirl between the injectors and intake ports will hurt the necessary tau factor or puddling on the runner wall required for running. a certain amount of fuel is puddled to make a film on the wall, greater so during idle and less of course under higher acceleration, this is mostly for sudden acceleration enrichenment but its there and serves more of a purpose than that. put a helix in the way and itll overpuddle and possibly flood the engine.

Throttle body spacers came about by a couple guys trying to make their carb run cooler on their racing engine. They put a 1 inch wooden spacer between the carb and the intake. In doing so they noticed an increase in engine torque.

In further developing the spacer concept, the reason for the power increase was found that by raising the carb it reduced the turbulence under the carb throttle plates allowing the mixture to "straighten out," for better flow into the engine. It also changed the angle of the incoming mixture as it turned into the intake runners which reduced "puddling" in the intake runners, and the extra length added to the "ram effect" of the incoming mixture.

In later engines swirling and mixing is done in the combustion chamber, not in the intake passages. The addition of a spacer on these engines may or may not help depending if the extra length adds to the velocity of the incoming air enough to change they dynamics of the airflow. Not all engines react the same.

Incoming air velocity is why modern engines have long intake runners, otherwise they would put the filter assy on top of the lower intake and save a lot of money.shady

i was reading in one of my books and fuel injected engines have a slight film that puddles on the base of the runner, known as the tau factor. ive been reading around a good bit, ill get the excerpt tonight and post it so you can see what im talking about. its part of a book on efi tuning, called engine management advanced tuning available at your local autozoo and cartechbooks.com. ive dug around some more on google on the subject and found quite a bit of info.

"Puddling" is found on carbs and tb injection. Some aftermarket manifolds build runner guides in the floor of the manifold to direct the puddled fuel.shady

funny the article showed it in a sequential port injected engine, ill reread and see what i find.
