Throttle body spacer for LS2

I found a throttle body spacer for the LS2 on EBAY about 2 weeks for 50.00. I have not been able to find one on any other web sites so I took a chance and bought it.. it did come with a full refund so I figured I have nothing to lose..I received it last week.. I have a plug in engine performance monitor and I recently had a dyno tune so I know what my baseline should be which is 380 RWHP,, after install I drove the car around for a while and the car seemed a little quicker and more responsive,,my onboard system shows RWHP at 388 so I took it for a dyno run,, the dyno run showed 389 HP , DAM,, so I really got about a 8 or 9 HP gain for only 50.00. not bad. and shipping for this thing is free, it came with longer mounting bolts. no gaskets needed,

I don't know if it will change my gas mileage, as of now I only put about 60 miles on it since install

If you want the info about these just go to their web site Vararam.com they also are being sold at Jeg's and Summit Racing,,what I forgot to tell you is that besides the 8 RWHP gain I also got a 12 pounds of torque increase. HP gains mean nothing without the torque increase

Dizzy1, what other mods do you have? If you have a CAI, did you by any chance dyno the car with and w/out it? I'm wondering what real HP gains can be expected just with a CAI, i.e. w/out a tune.

Anyone else with verified #s?

Throttle body spacer

all you need is a 10 M/M socket and a short ratchet extension.. install takes about 10 minutes.. after install, start the car and let it run for a few minutes till it warms up,, shut it off and re tighten the bolts,,,when you install it, make sure you put some ANTI SEIZE or some GREASE on the bolt threads.. I have had mine in about a week or so,, slight gas mileage increase, but more HP and Torque,, WELL WORTH THE 50.00

When I see the spacer on the Vararam web site, I can't "buy it" and it shows no price. WTH? It also shows only the spacer. On Summit racing, it shows the bolts, gaskets, and spacer. It's an Airaid Poweraid TBS Throttle Body Spacers and it's $100.00. Am I looking at the correct unit?:eek:

What the heck is this thing, and what's the logic behind the gains? I'm a skeptic on cheap mods a manufacturer could do, but that doesn't mean it's not true.
Sounds to me the AFR is being leaned out somehow (fooling the ECU), which is what tuners (and canned tunes) do, but only on top. If you lean out the whole rev band, AFRs would be dangerously lean where the EPA does its test cycle (where we drive most of the time). That's why I'm skeptical about the 'whole' picture. You know the adage: when something is too good to be true.... Later.

I am too...it is supposed to make a swirl in the air draw (similar to the "Tornado?")...what confuses me on these types of mods is that the screen is an air "straightener" according to GM so I don't know what causing a vortex would have if the screen (provided you don't remove it as many did many, copying the C5 Z06) only straightens the air back out...

The spacer goes after the MAF sensor and there is no "swirl" effect with the Vararam spacer, it actually has tiny ridges to straighten the air before entering the TB. I recently bought one and descreened the MAF just for that purpose. I haven't dynoed it since, but it does seem to make a minimal difference. :cheers
