He has a Fram on his car. But how can the K&N drop hp over the stock paper?? For that matter, how does a TBB drop hp? I was under the impression it doesn't affect hp at all??

I doubt the throttle body bypass is good for any sort of gain, but a 7hp loss? Nope, I don't think so.

As far as a K&N, again, I can't see it causing a loss over a stock paper filter. I do know that my Holley air filter shows a gain over a K&N and even no filter at all.

I called him on that a while ago and he got pretty pissed.

if there are no gains to be hab with the TBB then why bother i know there is very little expense just a barbed connector and some hose i know cooler air helps with KR maybe that is the advantage???? i really would like to know your thoughts on this

To fix that you got to spend another $180 on a MAFT... <img src="graemlins/burnout.gif" border="0" alt="[Burnout]" />

well i dont have a problem with KR i was just wondering why you would make the change if there is nothing to be gained there must be a reason to do it besides its cheap

I saw the following in 2001SSZ28:

Only do mods when you have a dyno. You will never know what works and what does not if you don't dyno after your mods(ie.K&N filter dropped my car 3 rwhp, Throttle bypass dropped it 7(makes the cars run rich)).

Anybody have facts to dispute this claim? NineBall? Patrick G? Anyone? Please??? <img src="graemlins/gr_cry.gif" border="0" alt="[whiner]" />

I remember someone saying something to the fact that as the car gets hot, it raises the temp. of the coolant. As the coolant passes through the TB, it raises the temp. of the incoming air through transference. If it is bypassed, when the car runs hot you won't lose hp due to higher temp. air. This is the theory anyway. Not any gain, just less parasitic loss.

My LT1 SS runs a little better with a fram filter over a K&N.

I ran 5 runs back to back, changing the filter between runs. It was with a new fram filter and a new K&N.

Fram-119.54mph
K&N- 119.14mph
Fram-119.61mph
K&N- 119.21mph
Fram-119.58mph

All 60ft's were in the 2.0's and et's in the 11.9-12.0 range.

Not much of a difference, but there was a definite pattern. I'm using a modified SS airbox, which uses a panel filter.

I've also went 120.4 through the fram on a different day (colder), but didn't have the K&N around for further comparison.

i have also hear in colder climates you can get frost in the throttle body anyone else hear this

I guess it's possible for the very same reasons why this mod is performed; cooling the TB. If bypassing it keeps it cooler for air-intake, then by correlation the TB could get pretty dam# cold in colder climates . . . and I suppose the engine heated coolant could keep frost from forming in and around the TB. I remember someone advising me to switch it back to stock if I were gonna be up North in the winter with the car.

Red Dragon

yes that is correct the TB plates can freeze and break in colder climates i switched mine back to stock lastyear but im not driving mine this year in the winter so i left it alone

Red Dragon

hmm... thats strange i gained 3 rwhp from a K&N but i didn't have a chance to dyno the throttle body bypass but when i did it i could feel a slight difference in the car you can feel the little it adds.

Another thing before i bypassed it after driving the cars you could touch the TB and it would be hot but after i bypassed it no matter how far or how hard i drove it or what the temprature was outside after i was done driving i could touch the TB and it was cold to the touch so the mod work's IMO

Again, less parasitic loss when the car is hot due to the fact that the TB does not get hotter (thereby raising the incoming air-temp.) from the hot coolant <img src="gr_stretch.gif" border="0">

I think both mods are sound and advisable.
