Hey Cls Owners,
you can get 10-15 horsepower more by doing throttle body. What is done is the core throttle body taking out and send to the machine shop to be bored bigger so more volume of air can enter the chamber. The ECU will adjust for this.

I have done this on my '97 XLE V6 Camry. You feel the difference throughout the RPM Band.

I Raced with 3.5 SE Altima with my '97 XLE Camry (Short Air Intake, Throttle Body, High Flow Catalyst Converter, High Flow Exhaust)

I'd have to see dyno proof of that....
honda did a pretty good job designing our intake I think we have plenty of flow for NA. a type S motor and a 97 camry engine are two different stories.

Been dicusssed quite a bit on here, a few folks have done it. I don't believe the gains where very good for a N/A application. If there was any at all.

Do a search on it. Or maybe someone will chime in who has done it.

"You feel the difference throughout the RPM Band. "

I doubt it It will lower flow speed at lower RPM causing a drop in low speed performance. Need to see low speed dyno run or results from a flow bench on the throttle body before I beleive this is anything but snake oil. Nothing in life is free.

Go bore yours, dyno and report back.

you spend the cash and let us know how it turns out...

I can vouch for a TB oversize bore - although you need to do more than just bore the TB; the intake manifold inlet port has to be port-matched as well. I went with a billet TB (few mm larger than a bored stock one) and it helped me hit 13.5's @ nearly 103 mph naturally aspirated - so it works!

The 10-15hp on a Camry is

ok maybe I'd believe it if you started port matching the intake manifold .. but I'm not buying 10-15 from a TB

you don't get any HP from boring out your throttle body. I've read couuntless articles about this in magazines. You mught get a better throttle response, thus your butt dyno telling you you got HP

IF you have a larger bore throttle-body AND the intake-tract is port-matched to utilize that larger size AND your engine is equipped to handle the extra air-flow

THEN you will gain power
