Heza Posted May 21, 2004 Report Share Posted May 21, 2004 check this guy out with his 3.4 DOHC Fiero. he raised power out of his 3.4 from 174 HP to 240 HP (at the wheels) naturally. has very interesting points and overall is a good read. http://fiero.cc/fiero-tdc/members/mws/intake/ Quote Link to comment Share on other sites More sharing options...

sonyman87 Posted May 21, 2004 Report Share Posted May 21, 2004 I would condiserdoing something like that if i had the resources.. im curious how he ran his coolant line? Break boot line and other vacum lines that are needed.. plus isnt running any 3.4dohc past 7k Hell on the heads without better springs or lifters.

DaveFromColorado Posted May 21, 2004 Report Share Posted May 21, 2004 ... that's where I came up with the idea of just guttin' out the upper intake. he lost a few horses at 3500 mark but the top top end more then made up for it. --Dave Quote Link to comment Share on other sites More sharing options...
slick Posted May 21, 2004 Report Share Posted May 21, 2004 Hmmm..... Interesting. So, basically he removed the upper intake manifold, and made a better flowing "box"? Correct me if im wrong on this. Quote Link to comment Share on other sites More sharing options...
4spdz34 Posted May 21, 2004 Report Share Posted May 21, 2004 very shitty design if u ask me. from the chart it looks liek it ahs no midrange power as if it drops off. that design is only good for a light car. Quote Link to comment Share on other sites More sharing options...
DaveFromColorado Posted May 21, 2004 Report Share Posted May 21, 2004 it looks like it'd be sweet in a 5-speed car runnin' up to 7500 R's shift down to 5k and so on. Personally, I'm not to worried about low end/midrange power, but if I wanted that back, with a gutted intake, I'm sure I could move the cam's 'round a little bit, and that'd see a bit more power. --Dave.

Correct me if im wrong on this. No, he electronically altered timing, and had exhuast headers on the car as well. At least thats what I got out of it.

DaveFromColorado Posted May 21, 2004 Report Share Posted May 21, 2004 his initial runs were with stock exhaust, cam timing, and his airbox, he did chip stuff later and showed the torque runs. --Dave. Quote Link to comment Share on other sites More sharing options...
