20-22 psi ok w/ t28 & supporting mods?

[LucidEclipse]

What do you guys think, 20-22 psi ok on a t28, 2.5" dp, 2.75" catback, supra smic, 1g bov, 190 lph fuel pump, 450cc (stock), mbc, gm maft, on c16 or the like for a couple runs down the 1/4? I have no logger, but may have one when I get to the track next time. Also, is c16 leaded or unleaded? Do you usually buy it at the track? Is there another fuel that may work better for my application? Thanks to all who reply.

You SHOULD be alright. I would try and find someone with a logger to make sure your car doesn't cut timing. If your timing keeps advancing then you aren't getting knock.

I run 20 psi on 92 and my timing climbs smooth as the mountain climber on the Price is Right. I do, however, have RC 550s and an A'PEXi FMIC but I think you'll be ok. If you don't have a logger, get one or borrow one. Your car may have significantly different results.

C16 is actually alot for 20 psi, and when i was running 20 psi on mine with C12 it was actually still running a little rich, and i was fine with timing, just a thought you could save some money on that expensive ass gas
