Last week I bought a set of Fiebruz Intake Manifold Runner Extenders (IMRE) and yesterday went to the dyno to see the gains I got out of them.
Dotted line is before the power blocks with all my other mods. Q300 Catback, Perrin 3" catted front pipe, and drop in filter.
Solid line is with the extenders, and all previous mods.
Both dynos where run on 91 oct and both are untuned
Peak HP didn't improve much, but this run was made on a heat soaked engine vs a cold engine from the previous time. Torque dip was reduced and peak torque increased froms 133 to 138, which is very nice, along with a much improved midrage curve.
This mod is probably the best bang for buck mod available for our cars at only $350.
Lastly, this week I got myself some Project Mu HC+800 brake pads... My god are they insane, so far on the street they bite so hard that I'm often overcooking the tires if I'm not careful
