TB Spacer

Post by HenryJ »

I think Steven was running a 1" spacer?

Anyone have any experience with these?

I'm thinking about adding the Helix for a couple of reasons.

#1 is that after the body lift the engine sitts lower than the air box and I'd like to raise the TB a little .

#2 I haven't been able to limit (eliminate) the EGR gas introduction as much as I'd like, so I'm thinking that the Helix may help mixing the gasses, without having to re-install the diffuser.

I have a TB spacer. I dont think I got any off the line power, but from about 20mph and up I noticed a difference.

Notice any change to the gas mileage?

Well , I decided to try one myself.

I bought the Helix.

It took about 30 min. to install , including cleaning up the threads on the supplied studs.

It did raise the intake tube to a better position.

So far no real noticable gains.

It will be a while before I can see if there is any improvement in mileage.

That is... if I keep my foot out of it too ;)

Thought I'd update this after running it for sometime now.

I'd say save your money if you want it for performance, or mileage.

It didn't seem to effect the mileage good or bad, performace hasn't changed much either. At least for the "seat of the pants dyno".



It did do two good things:

1- It raised the TB 1" (as advertised ;) ) which allows for a better fit of the air intake tube, after the bodylift.



2- It allows me enough clearance to change the thermostat without removing the throttle cable bracket :thumb:

Helix for sale on ebay

Helix spacer for sale on ebay.

This guy frequents the ZR2.com Forum. It is really cheap$ right now.

Some of the studs may be missing , but if it goes cheap it might be a good investment for someone who has a bodylift.

I'm not dissapointed in mine , though I did not really get a performance increase that was noticeable.

Sorry I missed this post earlier, I would have told you not to bother. I had one, and all I got was the whistle. No performance increase from what I could see, and no increase in milege per gallon.



When I installed this mod, IT was the only mod at the time, so I could really see what difference it made if at all. I'm told with the FI we have, knowone I know saw any difference.



I wouldnt recommend this one at all, But I guess I had to try it and see for myself.
