anyone running the helix 272/272 that gruppe-s is offering, or know any specs on them yet? the price seems to be unbeatable, but are you getting what you pay for compared to the hks? if the gains are comparable it would be nice to save a couple hundred bucks.

 

my sig. says it all

 

I have the helix 272s installed... with these, a tbe, intake, walbro and injectors, and only 21psi I'm at 330hp(275.1 gruppe-s mustang dyno), tuned at gruppe-s... I can honestly say they are pretty damn good... mind you this is without any aftermarket exhaust manifold, o2 housing, cam gears, ic or ic piping, and again, only 21psi...

 

well, i have everything in my sig...why do you have a pump and injectors (what size btw?) if you are only running 21 psi? when in the sequence did you have the cams done and how much of a gain did they provide? and blackevo, can you elaborate please? there's almost a $300 diff in the price for a product that has the same specs. thanks for the replies!

 

anybody else with any info?

 

I had the tbe and intake already, had cams installed and tuned... got the fuel pump and injectors because I'm going for alky injection in a week and had the lying around, just thought I'de get'em in now... got 25hp out of them and another 20~25 with the tune... I got 720s in, my idle sounds almost stock...
