Throtal body spacer

[97 30th RS]

According to zzperf, the intake spacer adds 8 whp at peak (5200 I believe) and 30 whp at 5800 rpm. The test was on a grand prix GT, with no other mods done. 30 hp to the wheels is almost 50 at the crank off an intake spacer?? That is what I thought until they dynoed it. Like I said, it sounded to good to be true, but dynos do not lie. I think it is a very worthwhile mod. I got it just fine from cheetahonline, but now the problem is putting it in.

if you get 10 at the crank you will be lucky. It's like adding a larger TB, more air volume meaning better top end and taking away a litle low end. IT's worth more just from the heating standpoint. But with radiant temps in teh engine bay after time the TB will get just as hot as before. You need to start it cool and keep it cool.
