I was thinking about getting the roadrace throttle body and intake manifold and was wondering what others experience has been with these? Is it worth the money? Is there a noticable difference?

 

just got it myself not too long ago and its well worth it and you notice the difference as soon as you start to drive the car with it

 

I've only read about those parts and hear that you get a much quicker throttle response most of all. Any part that allows the motor to breathe easier will help. And will definately help out later on down the road with any other mods you do.

 

I would suggest you search since this topic has been well covered in the past. You can also read my FAQ. I had both and to be honest didn't notice major gains, at least not the 10% or whatever it is claimed. What I did notice (better throttle response) could have been in my head.

 

RPW claims they gained 10 whp 14 ft/lbs torque with a 55 mm throttle body on a 4g93 with tuning.

They swapped to a 60 mm throttle body and added 4 whp 5 ft/lbs torque.

They didnt mention what mods the car already had though
