    Ignition timing for Methanol vs Gasoline

    Good point about all of the variables that comprise the characteristics of an engine and timing. Just for a little background here are a few engines that we have tuned and some rough timing numbers they use. Blown alcohol 377ci small block chevy mechanical injected (roots type blower because it...

    Cryogenic treatment for crank, rods

    Rink, I am far from an authority on cryo. I will try to get my guy on here to explain in some more detail. Cryo works equally well on ferrous and non ferrous with the exception of some stainless steels. All components of the turbos are treated. The process you spoke of is not the way my...

    Ignition timing for Methanol vs Gasoline

    Brobards to answer your first question the timing will be significantly higher. To answer your second question YES!!! I don't know how many of you have actually ran boosted methanol except for dynotuner but timing IS!!!!! the problem. Boosted engines on methanol do not like anything below 30...

    Twincharging SC>Turbo or Turbo>SC?

    Here's one that will make you all scratch your heads, a centrifugal blower compounded into twin turbos. It works fantastic and there is no lag. Try 2000+ horsepower on 4.0 liters. Just thought this might shed a little light on an old post. http://www.prologger.com/projectcar.asp

    two small turbos better than one big turbo(?)

    Twins will make way more power if compounded and sized right. I might be a little off beat here because they wouldnt necessarily be two small turbos. It is a matter of how much power you want to make, how much room you have(double the plumbing, double the waste gates, and double the intercooling...

    Cryogenic treatment for crank, rods

    Cryo seems to work really well. We do most all of our engine components including turbos(huge gains on turbo life!!!) It is kind of a stress reliever like shot peening. I think it would be a little redundant to do both. I have learned that things do move a little during cryo. It is a good idea...
