ExtrudeHone LIM-UIM
has anyone tried the ExtrudeHone LIM-UIM modification from rotorsportsracing ? any feedback?
|
Many people have enlarged their manifold runners/ports. I've never seen any before/after dyno's to demonstrate that it's significant enough to warrant the money spent.
|
how about flow matching? or is it just easier/cheaper to get the GZ LIM?
|
what's the price for this?
|
when i had my tiburon, i got a performance UIM that was similiar to extrude honed. grant it, it was a slightly larger shape than the stock one. but you could really feel a power increase.
easily 15-20 whp. i dont know what kind of results youd see on an FD though. |
That's a completely worthless post. You have no idea if it was the larger intake, ot the extrude honing that did it.
I looked into and called the company on it. They said it's more for flow matching that increasing the flow. They claim to have seen ~20% decrepancy between runners. The thing that I don't like about the extrude hone process is that it basically forces a mix through the passageways to clean out the nastiness from the casting. So what happens when the intake path takes a bend? The putty is going to want to go striat and could potentially distrupt the flow more. Just my $.02 |
There is some casting lumps on the inside of the runners that if you remove it will destroy your stock lim. If you want a better flowing manifold i would go after market.

Arent there guys making over 600 rwhp on the stock manifolds?
|
yeah i know a few but this will give a more reliable engine by the time u ll even the air flowing on both rotors and it will allow more air in
|
Custom "uim" ?
|
here's what i found..
