depends on the amount of meth you are spraying and what type of ign timing you are getting at the boost level. I can go up to about 18psi on a CM10 nozzle before my timing drops below 10 degrees.
fyi, i'm a stg 2.75 stock midpipes and exhaust.

I am at about <17PSI (In the 16s) with a dual CM7 and CM5 nozzle setup.
Here is a dyno I recently did at about 16.5PSI with the above setup running a 90/10 mix with pump gas (94 octane). Timing is perfect. I can push more boost, but I find this to be the sweet spot. Mike P.S I should note I have all stage 3 mods, except for the stock exhaust with stock mid cats. Last edited by Mike@N54Tuning.com; 09-18-2010 at 11:04 PM.. |

Mike - same setup as me with less boost. I need to dyno and compare to your results.
Edit - I run a single cm10 instead of the dual nozzles though.

Daily driving with 94 octane pump gas with 70/30 meth, I run 16.5psi tapering down to 15psi in 3rd gear. Full stage 3 mods running JB3 map 7 with meth map 8 enabled. Log below of a 3rd gear pull.
On the track I run 19.5psi tapering to 17psi running 90/10 meth mix on JB3 map 11.

Wow, looks like I'm pushing more boost than everyone else. I'm running 100% meth
When I get the car to the dyno I will be sure to try the high and low boost settings. For me, my timing is +10 degrees or better on 17.5 target with CM10, so if it ain't broke don't fix it I guess. Take a look at that log. 10+ degrees at boost even higher than 17.5; bet others could do the same easily. Procede progressive meth is an amazing failsafe as well.

I hold 17.5 psi with my M7 nozzle and 100% meth, i'll post some logs in my Aquamist review once I get my car back from the dealer (3rd HPFP and counting).

I think I could probably up the boost a bit more to say 18 on 93+meth, but it'll hurt timing I think. Guess I need to log that and see how it does....
