Performance ModificationsWant to talk about performance modifications for your Dodge Challenger? This is the forum for that. Anything from exhaust systems to power adders and everything in between. (Dodge Challenger Performance Modifications)
i was told , by few mechanics , dont waste money , in fact one handed me a peice of paper and said here go install that on your car , that how much differnce it helps, lol , i said ok , i got your point. but thats on a challenger , i got few freinds with trucks , that said they swear an will fight to agruee they see a differnce with a spacer. so the big question is if you feel good putting one do it , if you dont want to then dont , i dont think a spacer will make differnce that you will go wow , beter to just upgrade to 85 mm TB , or do other bolt ons. Enjoy !
For a motor that is largely built for bottom end torque like a truck motor, especially with big gears, by adding a big tall spacer (basically increasing runner length) you are going to see a difference in torque. While this is usually more noticable on a carb motor, I have seen some 350 based Fuel injected SBC trucks that gained like 14-15 Ft/lbs of torque, but it was because the intake didn't have long enough runners to begin with. With the SRT8, that intake has some serious R&D and since it already has some big runners, you really aren't going to notice a difference, especially in a motor built and camed for that broad of an RPM band.

I have seen pro's and con's of this and the one thing that is universal is that it will add a few ft lbs of torque. It wont help Hp that much in the higher power but the claims are in the lower power range you see a difference. I am fence sitting on this until I get a positive response from AirRaid (I asked for dyno proof on a SRT with a 6 speed as proof). I will share if I ever get a response.
If the spacer allowed longer fuel-air mixing, I'd say it should be a benefit.
But the throttle body spacer is before the fuel is added.
As far a air flow benefit: the spacer is immediately after the throttle flapper (increased turblence) which is immediately after a 90 degree turn (more turbulence).
Bottom line: If you have an extra hundred and feel guilty setting it on fire, donate it for a throttle body spacer.

I'll be honest and say that I did purchase the throttle body spacer from airaid when I got the K&N CAI. Do I notice a difference? Ummm yes and no. Yes I notice a difference in sound and in torque. I can light up the wheels even with the ESP on (not for an extended time). I say no because I haven't put it on the DYNO yet and I can't offically claim which part actually added "what amount" power, the CAI or the spacer.
So to help your decision is it worth your money: if its more than $100 don't buy it. You really won't notice a difference. If you're like me and get a little discount for buying several items at once, pick it up, who cares. To me its like a K&N drop in filter, you pay 50, 60 bucks but it lasts a lifetime and you pick up 1 or 2hp, more in torque, and a lil eye candy.
