Extrude Hone, anyone
I have been taking with the guys at Extrude Hone. sounds interesting. Has anyone here had it done and if so what are the benifits of it and is it worth 500 to have it done? Or if anyone has a comment on it i would like to hear it.
They say it better gas mileage and more HP 10 to 15

I can think of a lot of things to do with 500 before I'd send my manifolds off for that treatment.
But if you've gotten to the point where you've gotten the most out of your induction, I hear it's very effective. I'd bet that the HP figures are based on a car with a lot of exhaust and induction mods already, however.

I have never tried it personally, mainly due to what I have read in magazines.. I read a ton of car mags with engine builds and the like, and at the end of the day, the consensus from the magazine guys is always the same, 500-1000 bucks is alot of money for 2hp....
The biggest problem with the extrude hone, is that is doesn't have eyes, it only removes stuff its hits, which in theory is ok, but sometimes the overall shape of the port is the problem and not the small casting imperfections and little lumps here and there....Max

fart on a friends head!!!
be careful about smoothing out anything past the injectors. when fuel hits it itll just smudge and collect causing bad fuel mixtures. dont do anything past the injectors. the bumps in the cast will allow the fuel to move through a little easier. also, max is right about the actual shape of the intake and how its designed. . . i for one am not the fondest person of the way fuel is injected into the engine

If this is a turbo car I would not bother at all and it has shown very little power increase on heavily modified N/A engines. The N/A engine seem to respond more to exhaust work. spend the money on some a custom header and exhaust system and check on the dyno. intake manifold porting and polishing has not shown much bang for the buck in my experience and the experience of a couple engine builders and turners. turbo cars spend the money on intercooler and turbo upgrades instead.
