FP Evo Flow Advancement Port Cover
would the cover help improve spool or no? sorry if these are some noob questionsYes this is on 92 Shell. And if there was one thing that I could tell before getting tuned was that it definitely is more responsive in terms of spool. It also sounds exactly like all of the other FP turbo wheels do with this housing.
lol i stand corrected, good stuff...but hey you learn something everyday lol
OT: Aaron by any chance do you have any dynosheets of a before and after car with un-ported hotside vs. ported?

Hum, changing the manifold could easily account for the observed differences in spool and makes the change in power less concrete as well.
$200 for 20 HP is a bargain, so I'd love that to be the case.

I probably have the unported to ported hotside stuff. I didnt label any of that though so its more or less impossible to tell.
White---- both of these pulls made more corrected (367 to 385) as the conditions were very close. I will grab that from the dyno if I get a chance tomorrow. With exactly one exception I havent seen "power" increases from a ported anything exhaust I have only seen a decreased propensity to knock. That might seem like the same thing but its not. The gains I saw from a header or port job, where I could firmly say that made more power exactly once, was a Full Race header. On e85 there is no advantage on a stock frame turbo since the exhaust gas dynamics are so much different than pumpgas.
