Most likely locked. Old school setups over there. Old school works pretty good though. Thats how my high performance draw through engines were setup. My lower performance ones running up to 10 or so psi just ran a standard 009. My current car on gas pulls a half degree or so per psi assuming no methanol is in the equation. I think i add a few degrees on gas with meth. When running e85 i keep my timing mostly flat under boost, again, adding when meth is added to the mix.

E85 is amazing. If you have access, i highly recommend it.

I run draw through but mine is limited to 24* with a set screw in the tab.
Also I found 2 stations in town with E85 but they are both pretty far away and I don't think I could always get there. Water/meth injection I will probably do, but there isn't much info out there on draw through set ups.

Anyone running megajolt, CB performance or similar ignition systems out there ?
Or anyone that can help?
Need to know if I should start retarding as soon as boost starts or what till I start to hit 3 psi

Ps I started with a locked distributor that worked once I could get the engine started, then I moved on to a limited 009 distributor that worked a lot better now I have a fully adjustable CB black box ignition system witch gave me a lot more power when of boost but I ended up braking/ destroying the second ring on piston 3 and I don’t want to do it again. If it was due to to much advance or engine going lean I don’t know

Hard to say?, but I thinking it went lean with the cold weather and your icing issue,, with my 2276 off boost is like driving 'normal' N/A bug with a stroker :lol: but I would pull timing right as boost starts for 'Peace of mind' :wink: :lol: reason i run locked, then all I have to worry about is the fuel/jetting :D Have a 'Merry Christmas"

That's a good question, and something I hadn't really thought much about. I guess there is no real way to know what it needs. I suppose all you can really do is listen for ping. Do you have an AFR gauge? If not I would highly recommend it. I would have gotten that before the black box.
