Ha, no shit! I got the m3 for my draw through 1915, but have'nt gotten around to trying it out yet(as you may know, draw through setups and cold weather do'nt mix well). Within 2 weeks I'll be able to post up air/ fuel data. I'm thinking the m5 might be a bit on the large side, especially if you got the basic kit, considering thats what the vr6 people like to run around 15 psi. There are others on this site who may be of better assistance. Will you be running straight meth or a mix? I'll be shooting for 14psi with straight meth with the prog controller. So, what else do you have in that 1915 of yours?

i havent tried the water inj yet, it is definatly a bear to get warmed up in the cold weather,with a draw through.

its a 1915 steeve tims heads full p&p 40x35 valves.7.8-1 comp, engle 110 cam 1.25 rockers, t3 .42 .48 holley 350 2 barel carb. car hauls ass on 12-13 psi but has detonation sometimes and sometimes it doesnt? timing locked at 22

it does run on the rich side down low may couse soot on the plugs

im thinking i can run the m5 up the timing to 24 and up the boost to 15
probably have the meth come on at around 8 psi.
going to start off with 50/50 mix denatured alchohol and water, then try 50/50 meth and water see how it goes.

what do you think about this plan?
whats your combo?
