Alright i have been told that i need to use a G-valve to limit my boost with the vnt's... what the hell is it? I've never even heard of this until now.

What the hell in Vnt's? The only Proper way to controll boost is by the Wastegate. Some people use a Radiator cap to limit boost, so if you have a 16psi Radiator car that will keep you from going over 16 psi.If it cant Flow it, FORCE it!<br /><br />1999 M5 Camaro RS.

read it all and you will figure it out. VNT turbos dont require wastegates but it can be a good idea. Im gonna try it without wastegates at first and if the boost goes over my 12psi i want i will look into adding them. if you want to learn more about vnt turbos i will find the site that explains them in more detail but basically they change how the exhaust is directed at the turbine to allow for a quick spool up not add much backpressure on the top end.2001 Arctic White Firebird With Black Drop Top<br /><br />3:42 Gears<br />Zexel LSD<br />BMR upper A-Arms<br />Trans Am exhaust with 3\" I-pipe and cutout<br />Modified intake<br />Mecham Hood<br />Trans Go shift kit<br />Making rear control arms and panhardComment

VNTs -- are those like the now out of business aerocharger, with variable incidence turbine blades?<b>97 Camaro 3.8L M5</b><br />Car for sale<a href=\"http://terpmotors.com\" target=\"_blank\">terpmotors.com</a> Terrapin Motorsports! UMCPComment

yes they are similar. The difference is they can be had for 600 instead of 1500+. the only problem with them is the mechanism that changes the direction of the vanes (which causes the turbine to get differenct pressure forces) can become clogged with carbon build up. To comat this you must cycle the vanes by moving throughout the rpm range of the car on a regular basis. you can read more about it here http://www.chuckiii.com/Reports/Physics/VNT_turbo.shtml2001 Arctic White Firebird With Black Drop Top<br /><br />3:42 Gears<br />Zexel LSD<br />BMR upper A-Arms<br />Trans Am exhaust with 3\" I-pipe and cutout<br />Modified intake<br />Mecham Hood<br />Trans Go shift kit<br />Making rear control arms and panhardComment

I don't know if you found what you where looking for, but a G-valve = Grainger valve...Originally posted by T-Punk:
