I have a Camaro 3.8 97
Question is I got a power dyne supercharger with a 9 pulley on it now. Don't have header on yet. But does anyone know the max PSI I can get away with without header? I can change the pulley to lower the PSI on the supercharger if I need to. Oh one more thing, I don't have any cats on the exhaust it is straight pipe flow master no headers and K&N intake.
I'd say under 10psi.
You will likely be limited by fuel injector size and only be able to run low timing, somewhere in the 12-14 range.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
I can work with that. Thank you for the reply.
I already know about spark plug type and gaps. and lower the PSI I have no problems with. Kool time to have a little fun.
