I have not used one, but I have heard that they give an increase of power on a TBI engine, but not on a multi-port fuel injection engine.
Mine was a Helix and I purchased that plus the chip through JC Whitney. I think was are sponsored through them and get a discount if I'm not mistaken if you go through the link on our web site.Thanks Man...I have been on the fence about getting one for my 1995 but I didn't see anyone saying that they actually work.
What about the whining sound? I have to admit my hearing isn't that good. I probably wouldn't even hear it. I think I am going to order a Helix Spacer. Which one did you use?
I looked on the JC Whitney website and found listings for your application. Here is the linkYou know you got me thinking about this .....and frankly I didn't really put much thought into the idea, however, I started looking for a spacer for my 95 2500 Suburban 4x4 7.4 TBI. There is no listing for that model.
They have a listing for the CK Pickup 7.4, but the carb numbers do not match.
Any idea's why????
Is it the air cleaner spacing?
(I even raced a few kids and their imports from stop lights to show them the big red rig had some poop to it:lol:
I may be 41 but give me a reason and it feels like driving my 1970 Chevelle in hi-school all over again.....:rofl:Easy now! :rofl:
