Thread: Tuned topswap / SSM90; what's your WOT timing?

People who've done a Gen3 M90 topswap or put a ZZP SSM90 kit onto an L36/L26 bottom end and have tuned out the KR...

What kind of WOT timing are you seeing?

Also list:
-Pulley size?
-Octane fuel?
-Supporting mods?
-psi boost being made (if you know)?
-Anything else pertinent???

(Don't be shy if your support mod list is light, I also want to hear from non-IC people, non-header people, etc.; i.e., more than just the track beasts...)

on my L36...SSM90, 19* of timing
3.4 pulley
93 octane
rockers, plog, 2.5 catless dp, N* tb, 180* tstat, 104's, short stack intercooler
8-10 pounds, 8 consistently

May be a hard question to answer, but how much of that crazy high (IMO for a 3.4 pulley) timing ability would you attribute to the PLOG? To the SSIC?

Pulley size? Octane? No other mods? How much boost (psi)?

without the short stack i was at 11* of timing
i have a great tuner, its all tune in these cars, no one understands that. you dont need half the junk they sell to make power. its a 3.8 v6 nothing special
