what would be the advantage of boring my throttle body to 62mm would i notice and acceleration gains or HP gains on the dyno

 

Not really, the intake manifold and head needs to be opened up as well to really benefit from this.

 

i just put my skunk2 intake manifold and 64mm tb on my gsr. I can tell a difference on the ass dyno, as well as more torque steer!

 

a lot of the power that can be made will be from doing the entire intake side of ur engine basically, not JUST the TB, not JUST the intake mani, not JUST the port/polish, but all those three combined will give you better gains... u got to remember that opening up flow in your engine is pointless is pointless if it gets blocked inches down the line anyway

 

Exactly

Everything works as a system. You can't just throw parts togeather and expect it to work.

 

yea yea yea, i know that you cant just have the TB done and expect that much gains i jsut wanted to know what you would get out of just having that done

 

3-5 hp, MAYBE assuming your using stock intake mani

 

I want to say that 3-5hp would be really pushing it. False hope... I'd say maybe 1-2. In past I have seen this done with nothing else on the IM side and it yielded a big fat 0.

 

With the mods ive got, i can tell a big difference... BIG with just the sk2 IM and 64mm tb. Ive got a decent amount of torque steer on the low end where i didnt before. I dont have P&P either, but who knows about the future
