BEC MPG
was just sat and came to the conclusion I have absolutely no idea what MPG to expect when just driving the car normally.
I was thinking of driving it to a friends wedding in Lake Garda next year, but then thought what if it only does 20mpg, and i have to stop and fill up
every hour.
what experience do you guys running it have, Ive had high power light weight cars previously (not 7 light i must admit) and always found them to be
pretty good but ive never had a bike or bike engine so i have no clue
Suzuki claim 35mpg for the Busa but thats a bike not a car and ive no clue how the diff helps (or makes it worse)
thanks

Mike, I saw a post on here today where the owner of a 'Busa engined '7 type' said 17mpg and worse if he really caned it.
(Mini Z-car thread from memory).
Most disturbing!

yep that's what prompted me to ask, it seems pretty horrific in these times
like I say suzuki quote 35mpg but thats lighter and im guessing a lot more aerodynamic than a 7
I hadnt even considered it until i seen that post

My fury blade does about 28-30 if driven sedately and cruising at 70.
Quite hard to resist the temptation sometimes though :-)

Yes same around 30mpg if driven "sensibly" on the road bit more if kept to 50-60mph
Less sensibly or track 10-20mpg

The lowest I got was nine average at donnington on a very warm day there when I caned it all day and the best was twelve at cadwell in the wet. On the
road though I have no idea as it's a toy so I'm not bothered about mpg, I'd say drive it over there it's an adventure and will
beat any trip in a tin top besides you won't be going daft if you leave enough time to get there

Sorry to say this but Busas are notoriously thirsty 20mpg should be seen as reasonable. 30-35 mpg for the R1/blade.

If you take it steady and have gearing that keeps the engine are reasonably low speed then 30mpg should be within reach.
I got 35+mpg on a 100+mile run to Llandow with fuel injection on my gsxr1100 (before the turbo).
Now I have fitted the turbo the fuel gauge really starts moving! WOT in 2nd gets it as low as 2.5mpg, but only for a couple of seconds.

Edited to say, didn't realise Busa's were so bad for this. I bow to Jim's greater knowledge.

Yeah you can get over 30mpg (I think I've got 35mpg out of my injected R1 in the Fury) but a lot depends on gearing and drag.
If you're geared shorter then you're likely to be in the power band and this is where it'll start to drink the juice.
Also power required goes up with the cube of speed (twice as fast needs 8x the power) and that's mostly because of drag. If you've got a
car with an air brake for a windscreen the extra 10mph you might want to make good progress may cost you another 5mpg or so.

TBH you'll need to get out once an hour to stretch your legs. I can drive for a couple of hours on a spirited blat through the countryside, but
an hour on the motorway is dull and the prolonged / sustained high revs / vibration means I'm usually pretty glad of the need to stop and fill
up.

I can tell you that my Westfield Megabusa achieves 30 mpg when driven on a long distances at legal speeds, and to be happy about fill ups, tend to
stop every 100 miles or so.
The high fuel consumption figures would only normally be achieved on track days and, yes I have been in the teens to the gallon, but boy what fun.
If it can't be fixed with a hammer then its probably an electrical problem.

Our Fireblade engined MK used to return 28mpg. The ZX12R returns about 18mpg.

I get 30+ from my R1 Fury on the motorway. Goes down to 15-20 on track.
Don't listen to those who say you can't drive long distances in a BEC. I've done over 400miles in a day several times and so has
JimG... but we're just amateurs compared to Hobbsy.

Have gotten mid 30s on my remapped daytuner hayabusa engined MK running the standard 3.62 diff, cruising at 65ish on the motorway. 10ish litres used
in approx 65 miles. Much less when pushing though - went out earlier and averaged about 17 mpg.
To be honest i wouldn't want the car to have a longer range than 100 miles - I wouldn't want an engine doing 5/6k rpm in sixth gear for
any longer than that, and you will also need a break if you don't have a windscreen!
The busa bike has far longer gearing and lower air resistance - i'd bet a remapped one will get 40+ mpg realistically driven at the same speed.
With each month that progresses i get closer to buying a hayabusa bike, id love to try one.

Went to work in the blade the other week (I work nights) with 2 gallon in the tank, 17 mile run down M53, steady 65-70 used half a gallon, came home
at 100+ arrived home with an empty tank and grinning like a cheshire cat

Just got back from the South of France, did around 550 miles in the Rush while there. Trip computer tells me I was averaging 6.8mpg, I think thats a
little pessimistic!
If its broke, fix it. If it aint broke, take it apart and find out how it works!

I cant say i have ever taken my BEC out for a day without being a hooligan so i really cant say ive driven normally for more than 5miles at a time.
