Thanks

91 octane

todd what is the best psi to run tcd s1 at for reliability?

I believe this one has been answered here and there:

The S1 is non-intercooled (duh) - Todd has shown that we can still pump 20psi of hot/non-intercooled air into our cars without trouble.... but the headgasket won't hold out for very long. 10psi will last forever, 15psi won't -- but it will still last a good while.

You have an e34.... so.... I dunno - I was referring to e28s.

Not quite. Most I ever ran non intercooled was 18psi. Ambient temp was ~0F. I did run 15psi all year for 15k miles with no issues. But this was up north with good gas and proper tuning on a m30b34 motor.

8psi on a m30b35 is a good safe level.

awesome so when i order a wastegate from you what pressure spring will it have?
or can i request one at say 6psi?

I can provide one with whatever spring you want but I stock them with a .5 bar .

.5 bar??? fuck, i was only hitting 5-6 psi before the new mods and my gauge reads a little high.
