Thinking about buying an Accufab plenum...
 

Well, I was thinking about ordering the plenum since I have that 50 dollar store credit, but I was wondering how the gains would be on a pretty much stock 99 GT. I just want to get a decent gain for my money without having to buy the TB right now. Thanks for any opinions. :D

I have done a lot of research on these plenums, on a mostly stock engine, I think you will realistically gain 5-7 hp and 7-10 ftlbs of torque. I havent taken the plunge yet because I am waiting for all these rumored 2v manifolds to come out. HPS and BBK are supposed to have some reasonably priced manifolds, tenativley priced between 500-700 Dollars. I am waiting to see some dyno numbers on these. If I was to go with a plenum, Iwould definetly go for the Accufab. In all tests I have seen the Accufab performed the best in the low to midrange and was equal to all competitors on top end. And it looks awesome too. :cool:

Yea, im just trying to justify spending the extra dough for shininess and 2 extra hp...I need some near stock dynos...

I wouldn't go for an plenum just yet, I would wait, and just build up the suspension and get some sticky tires, I think they would help you better down the track.
