show us a picture of wha you have now and I will tell you whats wrong with them, also its liekly you need to do different mods to get what you want
im sick of driving my car with it feeling like a 6 cylinder. it has awesome bottom end and mid-range torque and all the power seems to be mid-range.
im after some extractors (and cam shafts but thats a different story) that will give my gze more top end power.
do you know of anyone who makes them or have any idea on how i could get my own made that will give me more top end?
im aiming at the 5500-6500rpm mark for peak power
*edit*
i know gzes are great for low-mid range but i want my power curve to even out a little and not drop off after 5500rpm

30kw club
Have you got the big crank pully already?
right now its running
nevo pulley kit (crank pulley, sc pulley) pushing about 13psi peak
modded abv
unknown NA 16V extractors
And what diameter exhaust and mufflers?
The normal way to raise the rev range is to fit longer duration camshafts, with some sacrifice to low end torque.
the power deleivery of yor car is inherant of any P.D. supercharged engine.
you could reduce the feeling with certain mods but at the end of the day you're always going to feel it lacking in the top end in compareson to it's low-mid range.
sorry to say but the only way to truely eliminate that feeling is to go turbo
dont know exactly the sizes but i think its 4-1 with it being 1.5inches into 2.5inches
i hear lenght of the extractors can effect the rev range. i dont know much about them thats why im asking about them.
camshafts i hear to use for the rev range i want are 256's or 264's with standard lift.
i thought about turbo but id sooner go worked NA than turbo. i dont want the issues related to turbo
<div class='quotetop'>QUOTE (Sam_Q @ Jan 5 2008, 03:26 PM) </div>theyre installed right now so even if i do get a pic you wont be able to see much
more top end power, lose the gze, and gain a gte.
i dont want crazy top end, just a top end gain over my current setup. looks like ill start with cams...
Even with cams you still have the problem like Benno pointed out. A positive displacment supercharger will start to become restrictive higher in the rev range
