    Default HP gain going to alky?

    Just a question about an option I've thought about. Currently running a kinda old school 468 BBC, 12.5-1, big Isky flat tappet cam, closed chamber rec. port heads, T/R w 2 750's. Nice, strong motor I guess is 550 HP. I run 110 Sunoco, timing at 38 total. Boat now runs a tick over 100, a pretty good ME 10 sec. class boat. Without changing anything else, but replace the tunnel ram & carbs to a stack injection or hat on a T/R and running on METHONAL...........how much horsepower could I gain? Jocko

    its been proven tha t there isnt much hp gain on alky vrs fuel..what you do gain is decrease cyl temp and over all cooler engine temp plus a bit of cylinder fuel packing and crunch..down fall is cly wash and oil dillusion and lack of performance in some cases due to lack of temp... need to be a temp deal or alky isnt the best choice..its nasty and corrosive..its not very engine friendly at all

    All other factors being equal your looking at 0 - 4% gain at best.
    If the engine runs too cold to vaporize the fuel you will loose performance.
    Methanol vaporizes at 150 degrees.

    Where methanol really shines is at cylinder pressures above where gasoline can run.

    what about ring gaps? would they be ok for alky? .015 to .020 on the top, if i remember correctly, but each piston and ring types are a little different

    Default Alky

    Where alky shines is in crazy high cylinder pressure engines. It has a very high resistance to detonation. A good example would be a blown alky funny car. High compression and insane boost. Also it is its own inter-cooler. With a race gas unblown tune up, you probably will not see to much of an improvement. You will defiantly run a lot more alky thru the motor than gas. It is way cheaper than race gas, but it does not have a very long shelf life. Sucks up moisture like a shop vac.

    Yeah, like you would know.


    If you don't squeeze it enough, its a waste, and only polutes your oil.
    BUT.... if you pack enough in, and squeeze it enough, you have no heads, no head gaskets, no head studs or bolts, no main caps to blow clean out of the block, you can make 1000+HP from 181 inches, at 10,000RPM and have it live for 500 miles STRAIGHT.
    may explain why Ford insisted on the fangs being removed from a little 4 banger built in a tiny little shop in Los Angeles back in the 60s They simply couldn't make that kind of cylinder pressure and have it survive.

    No cylinder heads, head bolts, gaskets etc. 4 cylinder. Made in Los Angeles on 2001 w Gage Ave. (The Ghetto) There is a slight chance that GN-7 is talking about an Offy. Ford made Indy limit the amount of fuel you could use and that killed the Offy.

    Saw one back in the 70s. Think about machining that block and head before the days of CNC's. A lot of time, work and talent went into those engines.

    They limited the total fuel alotment, the amount they could carry onboard, and the max boost. Ford didn't screw around. They covered every base they could.

    Seems they are smarter than the guy that is singing their praises.

    Yeah, Ford was just great during the 60s Indy era. If you can't beat some tiny ass machine shop in the ghetto of L.A., then crush their ass under rules that you bought with your vast money. Its the American way.

    Than goodness you aren't one of the guys I hear whining like little school bitches about how money is ruining racing.

    Its not easy RACER, but somebody has to do it.
    Thank goodness we have people like you to put FEs in trailer boats so that we can remember the "good ol glory days" when Ford actually built a competitive engine package.
