Most likely I'm going with a regular HKS unit. It worked great on my dad's fully built stockblock car and held 27psi no problem. I don't care about the sound it makes, I pefer quiet. One I won't even consider is the HKS SSQ valve. On my dad's stageII car, I cringe everytime he lets off the gas. It makes a horrible screech. Any suggestions? Something that will work with the TRs and not cost an arm and a leg? Remember this is a hotair setup, I have an extra 5' of 3" piping over you guys.
