In Sweden and parts of the MidWest US, E85 (Ethanol 85%, Gasoline 15%) is readily available. Soon also E100.

Here it is used by many for it´s value and/or environmental properties.
Some however use it for other reasons altogether.
On a turbocharged engine for instance, you can get rid of the intercooler, increase boost and/or static compression and voila!
(Well not quite that easy, but...)

895 hp out of a 2,3L SAAB. 2-stage nitrous adds another 175hp for a total of 1070 hp!

My simple question, racers, is if this fuel can be to our benefit aswell?
I am aware that cold starts in freezing temps can be an issue.

(PS, an old friend of mine, Stefan Verdi, made the con-rods for this beast...)

No reply about the fuel, but WOW about that power!!!!

With increased fuel delivery, advance ignition timing, a bump in compression ratio and / or boost a marginal improvement can be had using Ethanol mixtures.

Power Scale for comparison:
I do several 100% Methanol conversions each year with an honest 10% power increase being the norm if proper timing and fuel delivery are insured. (all else remaining equal)

wheelie bars and it is front wheel drive?
Am I missing something?

hey good point SFO.. look at the tires, what gives?

Marketing or Merchandising?

On a relative note:
Axial mount, contra rotating, crankshaft balancer? :)

To my knowledge the "wheelie bar" being so close to the ground would prevent the chassis to rotate
during initial acceleration, keeping more weight on the front wheels.
However, in all the races I have seen him, he has run without it.
They are having serious problems getting the power to the ground.
Every gear shift he´s on the rev limiter pretty much burning rubber.
What you see is a result of that.

Aren´t we backwards in Europe???

Needless to say, they only compete against other front wheel drive cars.
Running alcohol, they could eliminate the intercooler, reducing turbo lag.
(Lag would affect him a lot since he´s got "regular" clutch and stick shift.)
The choice of E85 over Methanol is due to the fact Methanol is not considered "Street" fuel.
This is what I´ve been able to dig out. So, no, it´s not a gimmick.
Nice try though, Dale! :D
 
Of course I was merely joking.

Truthfully I figured such was a lift safety to prevent flipping the car during a high speed run.

The wing should probably go on the front if down force related traction is the objective. :D
 
Hi All,

If memory serves, I believe that when converting to alcohol in a typical motorcycle carb one needs to increase the main jet size for starters by a factor of 4. I'm not sure whether that's true or not, please let me know if that's incorrect.

With the increased fuel flow comes a decrease in fuel mileage. I was watching a show on the history channel the other night and they were highlighting Brazil and how alcohol was readily available at most fueling stations. The fuel was considerably cheaper, but, the show noted that it took almost twice the amount of fuel compared to gasoline. I'm assuming that's because of the available btu's per gallon. For instance, I believe that there is about 100, 000 btu's in a gallon of gasoline, and about 145,000 btu's in a gallon of diesel.

As long as it was legal, I imagine it would make a good fuel for shorter races.

But, since it so readily bonds with water, doesn't it take a lot of special handling? Like draining the tank when not in use, and or putting in straight gas to keep things from getting gummed up?
 
when something-anything-absorbs water it is called hydroscopic. drag racing isn't big in europe. we don't go for big and fast we tend to introduce more rules and shapes in the circuit that put an onus on handling and keep the costs down.

for instance, for us, stock car racing is abround a 1/4 mile oval and it's full contact. i took a friend from rapid city and he just didn't get it! no speed! no sponsors! no pazzaz!

Fuel delivery "area" must be increased a minimum of 130% across the entire board. (ie 2.3 x that of gasoline)

Methanol = 57,000 BTU per gallon.
BSFC is often near 1.35 compared to an average of .6 for gasoline.

Methanol is a near perfect fuel for sprint competition.

Keeping it "Neat" (ie dry) and exercising due caution while handling are considered paramount. Methanol is extremely poisonous.

Kind Regards,
Dale
