My Very Slow Build

[michael parris heuberger]

I would warm it on Gasoline
then switch it over
Idling M1 that long tends to contaminate the oil

Hi. It is to hard for me to switch over at this point.

If you think idling puts alot of fuel in the oil, You should see how much gets into the oil when running 9000cc/min of methanol at 40psi boost

I was under the impression idling was the culprit.
I may at some point try E85 if it ever becomes available here

Hi. You can get a better mix from VP. Or you could VP X98.

Hi. @ sportbikerider. How often should I change the oil? I will be doing LSR.

What do you estimate that power to be? Would you calculate it with 2 BSFC or less? I’m trying to size injectors and a fuel pump for turbo on methanol but I’ve heard some calculating hp requirements with BSFC for methanol as low as 1.2 and high as 2.2

Hi. About 800 easy on VP C16 about 1000 on VP M1 I have the michanical pump from DME. Bottom ID 1050cc top ID 2600cc.

Are you racing 1 mile or 1.5 miles?

If you’re using the mechanical fuel pump, it takes the place of the water pump. Do you still have water running through the block?

Hi. It is for the street, LSR 1 mile then 1 1/2 mile and a little drag racing. I actually have 2 electric water pumps one for the motor and one for the turbo intercooler. 1st pic is bottom injectors 2nd is upper injectors 3rd is my RCC plenum from Power House.. Are you using mill special wire and connectors? 508-496-3312 call if you want.

40+psi boost puts alot of strain on everything. Idle can be rough, especially if the injectors are really large and have a hard time operating at very low pulsewidths. I went to an 8 injector setup for my Prostreet turbo, with only 4 active at low RPM. Still have milky oil very quickly.

Hi. @ sportbikerider. How often should I change the oil? I will be doing LSR.

If you are making multiple real LSR passes under full power, probably every evening after a day of racing.

That is on a bike that is over 700hp
Using a standard BSCF is sort of moot as people tune all over the place as far as lambda values.
There are bikes that use 4X 2200cc injectors and make mid 700's for HP.
For a gen2 style setup, using 4X 2600cc and 4X stock is a pretty good combo for methanol as long as the ECU used will support injector staging. That combo could support over 800HP.

800hp easy on C16 and 1000 on Methanol? In what world is making 800HP on C16 "easy"?

Is this a youtube version of Horsepower?

 

[202mphbusa]

I am in the final stages of adding the staged injection to mine
JUST 910cc secondarys to go with the 1000's in priamy

Thanks! I’m just trying to do my homework with a nod to the six P’s. Proper planning prevents piss poor performance. I think BSFC is still useful for sizing fuel injectors/pump.

What electric fuel pump would you recommend for alcohol? I’m thinking of having a custom 2 gallon fuel cell built and use an electric inline pump.

Using a number for BSFC will get you another number for injector size. Change one, and the other will change. It is just linear math. Guessing on one or the other yields the same =end result...a guess. Methanol will burn and make power over a lambda range of .6-.9 (even wider than that). How you choose to convert that into Horsepower will determine the BSFC.

The same engine with the same lambda with just a timing adjustment could very the BSFC by 10% or more.
As for a fuel pump, again, it depends on how much power you are planning to make and under what conditions. There aren't many electric pumps adequate for an all out turbocharged methanol hayabusa build. Fuel pressure will play a large role in pump selection for an electric pump as the flow will dramatically drop off at high pressure. That is the main advantage of a mechanical pump...the available tq to drive it is relatively infinite as compared to an electric pump.

If it is an extreme HP street application running methanol, finding an electric pump would be very difficult without significant upgrades to the charging system.
But that said, a methanol street application isn't really practical either...so they sort of go hand in hand lol

Hi. If you want to make big power you my need 2 pumps for alcohol. Also you would need a heavy duty chargig system an it may still not be not enough. It is hard to make the bike work on the street and to race. I am working with Eric at DAS and DME and others.

 

[202mphbusa]

the build has been going on for 6 years now. what he is doing is uncharted territory basically. would be nice to hit the start button on that build... and DAS is a blower expert, not a turbo expert. im just gonna say it like that.

Sorry but You could not be more wrong about DAS turbo experience
he was hand building turbo kits for his oil cooled in the 90's
there are at least three pro street level turbo bikes out there built by him

 

[airborneuph]

Eric had a beautiful gsxr 1100 that he turbocharged ln the early 1990's .. Single throttle body plenum too, used a GM throttle body . And gear based boost control which used carburetor Jets to bleed off boost .. He wouldn't tell me how it sensed gear position though .. We were all curious to know how he managed that .. The bike was ultimately stolen if I remember correctly ..

Hi. He is also a LSR word record hoodere. If I had F 1 money it would have been done 5 yrs ago.
