There all stupid right? Your biased and have a one sided mind. The big wheel concept is great, complete drop in and usually the gains are 20-45hsp across the board. Lose 200 rpms spool and gain 30hsp across the board...stupid, i know
.
Your retarded, you should have kept that post to your self.
Some of it is supply & demand. With people demanding these to be made, vendors would be stupid to not follow through or they'll loose that money to other vendors.
All the dyno's I've seen haven't show even 1/2 of the gain you're claiming across the board (at lease not without bigger injectors, fuel control of some sort & more boost). At this point you might as well be tuning a 50 trim. The spool & broad powerband is what make the S3 so bad ass. Trading spool for more power is like trying to teach a cat to bark. If I want to hear a bark I'll go buy a dog, i'd be a lot easier. Make sense?
If you have some graphs you'd like to post please do. I'd love to see something good associated with the big wheels. I know of someone who makde 440+ on a 44lb wheel which is good. The problem is it wasn't a big enough gain for the money invested. He sold it & went big big big turbo (which was about the same degree of difficulty tuning except with a better payoff).
My S3 feels is as fast on pump as my 50 trim was on pump but I'm making about 50 less HP. The key is I'm making it sooner & holding it longer as well as making quite a bit more torque.
Just to re-interate my point, Here's my dyno overlays (it may not look that significant but trust me, every rpms of spool counts big time with a 6500 rev limit, plus cars don't make load on a dyno like they do on the street so spool is more significant than it appears).
Red = 50 Trim @ 20psi on 91
Blue = S3 @ 25psi on 110
Green = S3 @ 22psi on 91
*this is also at 5200+ft altitude*
