Brand new dramatically large compression ratios it is possible to that have methanol lead to similarly big horsepower increases during the early days. Modern racing energy have swept up towards octane, but methanol provides secret safeguards pros you to definitely ensure that is stays on forefront regarding Western race. Methanol is very easily toned down by water, while making a beer flame more straightforward to put-out than just a fuel flame. Therefore injury cold and reduced than simply gasoline, meaning that it is much easier into system parts.

The V6 solution

An alternative choice in some sanctioning government is V6 electricity. USAC made V6 power courtroom some years back if this featured Detroit was going to phase from the V8 due to electricity discount concerns. As they was on it, USAC also provided the fresh new V6 proper lbs split, in order for V6-driven automobiles will have besides a competitive fuel-to-lbs ratio, but an effective line inside cornering also. V6-powered sprinters enjoys won a great amount of USAC low-winged racing to your sidewalk. And you may Kurt Martin out-of Chico, Ca reports that Draw Hall’s #54 is actually a normal champ on Northern Ca 360 circuit which have a good 317 cubic inch Chevy V6.
