:scottm: Has anyone tried a throttle body spacer? Does it make any difference in
performance?
thanks.
performance?
thanks.
bfred said:Same with aftermarket exhaust. Larger pipe diameters work great for higher rpm's but can hurt the bottom end. Not enough backpressure at low speeds ruins the scavanging effect that helps pull exhaust gases out of the motor.
The fact that you have noticed anything is a miracle in itself.TRSCobra said:I put a poweraid spacer on mine and noticed it immediately. Throttle response is better, among all the mods i've done (catback, k&n, livewires ign. kit) it was the only thing that I actually noticed a difference.
I agree with Cobra. TBS, by itself, u probably wouldn't notice jack. But with a catback, CAI, chip, etc..... it definitely helps. Not so much in raw power, but I noticed a huge difference in throttle response as well.TRSCobra said:I put a poweraid spacer on mine and noticed it immediately. Throttle response is better

the best way to NOT know if a particular modification helped is to make several changes at once. Who's to say which ones helped and which didn't?jbmoose said:I agree with Cobra.

none of my oxygen sensors know how many cfs's (or cfm's) the exhaust is flowing.j99xj said:... the computer will know if the exhaust is flowing more cfs (oxygen sensor) ...
Yes, of course the oxygen sensor by itself won't know the mass flow rate, but that's not what I meant. I meant the computer would use the signal from the o2 sensor to help it guess what the flow rate is.MaXJohnson said:none of my oxygen sensors know how many cfs's (or cfm's) the exhaust is flowing.
The computer doesn't use the signal to determine flow rate in any way, shape or form. The computer does care about air/fuel ratio. It doesn't know or care about flow rates(air or exhaust).j99xj said:Yes, of course the oxygen sensor by itself won't know the mass flow rate, but that's not what I meant.

I probably wouldn't come back and say to you "If bigger pipes are better, why didn't they come that way from the factory?", but you did. By your logic, smaller pipes are less expensive, so why didn't the factory put on smaller pipes? In reality, engineers specify the exhaust based on compromises of power, economy, cost, noise reduction, ease of manufacturing, material availability, etc. Depending on the target market, they may lean towards less expensive or more expensive in a gamble to sell more units.j99xj said:You will probably come back and say to me "If bigger pipes are better, why didn't they come that way from the factory?" That is easy. Bigger pipes are more expensive and that would do nothing for Jeep besides reduce their bottom line profit. Car companies are in the business to make profit, and they will do everything they can to maximize it. (I have no problem with this, it is just the way it is, a captialist system, which I am in full support of.) But that just opens up many opportunities for small businesses to make aftermarket parts, which I am in full support of also.
