I hear you...eventually I'm going to put some synthetic in the tranny along with the Mopar additive and see what happens....

Speaking of STS's, I know this is WAY [sm=offtopic.gif] but coming out of the boot is the STS slanted? or does it stick straight up like the OEM shifter...

 

ive got the manifold and 60mm t/b from modern performance big improvment in midrange punch and much better throttlle response below boost and at part throttlle.

 

Word; extrude hone is the process of pumping an abrasive putty through any kind of tubing or manifolding to "sand" or "polish" smooth the interior walls of the manifold. The singular advantage of extrude honing is it can get into areas you can not manually get to with a hand held rotary tool. However, what Gary said is correct in that it is "mindless". It sands all surfaces equally which is not really desireable from a power production standpoint. A key part of power production in an engine is air velocity. Simple physics will tell you if you push a set amount of air through 2 different size holes, the smaller one will have more velocity. True, the larger hole can flow more air totally, but the velocity is lower at every point below the max. The deal here is to keep velocity up while not being restrictive. The intake manifold and the ports in the head that they mate to "charge" the cylinder on each intake stroke. Higher velocity ports charge the cylinder better at lower speeds and will continue making more power than a too large port can all the way up untill the ports small size itself becomes a restriction. What you pay a good porting specialist to do is remove rough edges, match mating port windows and recontour key radiuses inside a manifold or head port all while not substantially enlarging the port to get the best of both worlds; maintain high velocity while at the same time, increasing port flow potential by removing areas that create turbulence. That's why hand porting is better than extrude honing. Going really big in the ports only benefits an extreme racing engine that turns a whole lot more rpm than we do.

 

this has got to be the most informative thread I have seen in a long time I have been debating on which direction to go for a while now now I know THANKS PRESSURECOOKER

 

You are most welcome.

 

Bump!
