[QUOTE="jdgleason, post: 93707, member: 166"] Well that depends. Are you using the 4202 for a primary or an atmosphere? For an atmosphere, a 4202 may be on the small side. You can have it make as many psi as you want, you just have to take into account that the air that the 4202 is feeding the primary will be compressed again. So say that 30 psi is compressed agin going through the primary, you could have 100 psi going to the manifold pretty quickly :eek: waste gates will control the pressures there. Another thing to keep in mind is waste gates can only flow so much. You may need a couple gates to be able to bleed off that much pressure. If thats the case, your back pressure is getting kinda high- gotta strive for that 1:1 ratio. As for dumping the gates- the gates will be dumping exhaust. Most DD trucks will want to dump back into the exhaust so that they dont cover their fender wells, engine bay and undercarriage with soot. Personal preference i guess. [/QUOTE]
