Are people happy with their Extrude Hone of intake tracts. Would you do it again?

I don't mind spending the money even for a 2 Hp gain, but I don't want to mod a new LIM and UIM set up and find that I lost a chunk of torque somewhere in my powerband and then need to go out a buy another Xcessive LIM and JDM UIM. Wasting time and 2000 just to get back to where I am.

 

I won't be too helpful with this topic but I don't know that anyone on this board has done an extrude hone.

Howard Coleman mentioned that he had his manifolds ported and Pettit now offers a porting service for the intake manifolds as well. Figured I'd mention that in case there isn't any other input to be had.

 

someone was/is selling an polished extrude honed LIM on here. this is the link for his FS thread. mabey give him a shout and see what the deal is.

I'm sorry but can someone explain to me what an extrude hone is?

 

I did it years ago, in conjunction with other mods so I couldn't isolate the effect. I don't think it was worth it. The passages are smooth as silk, though.
