Hi

Fiddly day today;
Drilled and tapped holes for jacking bolts and disk mount holes in the brake carrier.
Made the bearing and axle spacers for the back wheel.
Shortened the back axle, need some stainless threaded rod to finish the adjusters.



Cheers

40 weeks till Speedweek 2013.  :-o

Does anyone have a rough formula/ rule of thumb for fuel requirements based around blown hp running on methanol?

I worked out 10litres should do me for a blown Busa fueling each run but would like a sence check.

Thanks

2 and a half gallons should be plenty ; at least for the short course.
others should be chiming in.

I think my 120" gets about 12 miles to a gallon. and that's low balling.
on gasoline.

Jon, no good info on methanol, but running the busa blown gas we used 1 gallon per run... You may be cutting it close.  Max carries 7 gallons of methanol for his 180 ci. 
You might want to have 15 liters... just in case... its  better to have a little too much than.... well you know

Thanks guys;

Stainless; do you know how much Max uses a run?
How much Hp you making with the Busa if you don't mind sharing?

10l will be plenty for gas I think but don't want to have to remake the tank and move everything if I need a couple more, like everyone else space is at a premium.

Thanks

Hi Jon,

Try that, no pumping losses included:

Air requirement per mn, normally aspirated
(Cyl in litres + Head in litres) x number of cyl x rpm/2 (4 stroke) = AR

Then Boost ratio:
(atm pressure (14.7) + turbo boost)/turbo boost = BR

Then air requirement per mn, with turbo:
AR x BR= ART in litres

Then weight of air in ART = (ART/1000) x 1.2) = ARTW

Then Methanol bit:
ARTW / 6 (meth to air mix ratio) x .792 (specific meth gravity) = meth needed in litres per mn

Hum, thinks it's right!!!

How many hp are you aiming at ?
French  Owl is probably right but math was never a strong point of mine so i keep it simple
12.5cc/hp/min will get you in the ball park, then add a safety margine
Are you counting your amps, methanol pump if electric will use about 15-18 at a reasonable boost level
water pump about 4  :wink:

Thanks guys

I will be aiming for 15l, should do the job and not take up too much room.

Maybe a decision point on fuel load; when you come out of impound after first half of your record, its nice to be able to go to the line without the fuel truck pass.  One less distraction right before the run, and maybe one less chance for a problem when the bike was perfect on the up run.

Thanks for your confidence JimL, I hope your right oneday.

I'm not wanting to carry excess weight and I'll be chasing ice etc between runs anyway.

Hi

Orange Aid SFI rollbar padding turned up last week;

It's not "soft" bit its way better than any of the other SFI approved stuff I've seen in shops.

Simpson Pro Rage turned up yesterday;

Had a quick test sit before going to work this am, it is pretty unobtrusive for getting in and out and when sitting in the bike, pleasantly surprised.

Will try and get a pic of shoulder/neck/helmet area before Dave goes back on roster.

Will take both the Pro Rage and Orange Aid to Lake Gairdner in May if any of the Aus guys are interested in having a look.

Cheers

methanol- fuel class.
your gas-  fuel class.

both = no stop at the gas truck line.
