Re: So who here thinks that the 2.5 inline 5 is detuned??? (konafoci)
honestly, i believe not too many people know alot about this engine, myself included. we will not get to the bottom of this, unless someone (or many people) mod their 2.5s.
if this engine was detuned, i DO believe they put a bottleneck on it by through the intake, exhaust, ECU, AND cams. i think it can easily create 170whp and 180w lb-ft.
the only way to get to the bottom of this is to just mod the 2.5.
create an OEM-like intake, like the one found in MKIVs and the New(er) Beetle.
install a freer flowing exhaust system, but nothing that screams "im modded people!!! hear me ROAR!!" but it MUST have a cat, because the object is to be OEM-like (OEM+ maybe?) for the intake/exhaust.
remap the ECU, raise the redline higher ONLY if its safe to do so, and if its safe to run at those speeds for longer-than-usual amount of time.
design cams that are made for slightly better performance (both down-low and up-high)
if only i had the resources http://****************.com/smile/emthup.gif someone better try this
