Alcohol conversion for a mini sprint
 

What does it cost to switch a stock gsxr1000 on gas over to alky? Who does this type of work and how involved is it? Thanks in advance

As someone who is going through this process with my car right now I will see if I can give you the basics. This is my experience and there may be others who can do the work or cheaper parts, this is just what I have found. First off, your injection stack will need to be converted over. This involves changing out the injectors to ones that put out about double the fuel load of the gas injectors. In my opinion figuring out which ones are needed is best left to the pro's. The fuel rail is usually swapped out to allow for the extra fuel demand and generally converted over to AN fittings. If I remember correctly some builders also anodize some of the parts to help with the fact that alky corrodes aluminum rapidly. Hyper racing charges $1000 to convert your injection stack over. After this you are going to have to change air filter boxes to get enough flow to feed the engine. The cheapest filter I have found runs around $200-$250 with most running more than that. After this comes the plumbing. You will need to run all new fuel line, AN fittings to put it all together, at least 1 filter (most folks I know run 2), a high pressure fuel pump and fuel pressure regulator and gauge. Then throw in a power commander to change your air\fuel mixture. All said and done you are probably looking at around $2500-$3000 (give or take) to get yourself switched over if you buy all new. As far as who is doing the conversions the 3 that I found are Henchcraft, Guhl and Hyper. There are probably others, those are just the 3 I know of.

Is it a 4 or 8 injector motor? Do you want a non stock air filter or stock air filters? Do you already have a power comander? Do you already use an automotive flow thru type fuel pump? Do you have a fuel regulator? Do you have an aftermarket fuel filter? All of these things add up. If the answer to most of these questions is yes. AJ Felker and I can probably put a fuel rail, and 4 injectors with dyno time for around $800.00 to $1200.00 :6:

Don Guhl in PA is the man to talk to. He did a couple of the cars I drove and its a perfect setup, he condenses the harness to where its manageable, and with his quick click system, a moron could put it on the car, I should know, I've done it.

we just got a rossom injection it was about 3500

Alex u should have put it together yourself. Can be done much cheaper.

Everything you ever wanted to know about methanol conversion but was afraid to ask: "we have the technology we can do it ourselves"

I didn't want to start a new thread so i figured I'd ask here....

What is the point of doing a alky conversions on mini sprints?

Safer , more power, motors run cooler, makes motors last longer.

Does it have mechanical or electronic injection? You could give Daryl Saucier at DSR Fuel Systems a call 317-490-3410.

Ok, but it's not a must per say?

Reason I ask is I might want to but a roller and then build my own motor. I don't really want to mess with alky if I don't have to. I can make power without alky so I'm not worried about that.

I guarantee you with stock motor rules at the end of a 20 lap race you will not be making more power than an alcohol motor... And yes it is a must when you find out how hard it is to cool itself ... Why are you against it??? No different .. If you don't race every week just start the motor on gas takes 5 min and let the gas stay in the injectors and lines until you get ready to race again... If you race every two weeks just start your motor on ur off week for a few minutes that's it... No other maintenance at all!!! Clean alcohol is clean fuel system

And add a little uplon from Klotz, and help the rings and valves, and bores! Bob

That's good stuff; I just dismantled my fuel system after 2 seasons (with little to no maintenance) and she's clean as a whistle...

Forget the idea about going into motor building. These ain't your average 350 chevy. The equipment and measuring gauges are probably not at your disposal and these things like to stay in the .0001 +/- tolerance level. Running gasoline is fine >>in fact if you want to invest in some $20.00 gallon race fuel in 5 gallon cans you will make more power than you will on Methanol. BUT if you want to run any kind of Gasoline invest in a good electric fan from a parts store and run it all the time, and keep the darned thermostat in.

Having Raced Mini Sprints for years I have found that the motor is the last place I would look for a performance advantage. All of these new 1000cc motors come out of the factory with engines producing power in about the same percentage of a Formula one race car>>>not much room for improvement there. Now driving and handling you have all kind of room there for improvement.

You might also want to consider buying yourself an alcohol hydrometer, and ck every bbl, or gallon you buy, it is usually all created equal, but as it's primary use is drying propane, it depends on how much it's been used, therefore how much water it contains, or age, or other stuff! Bob

Im not against alcohol conversion at all but the cost seems prohibitive for a class that is supposed to be a entry level club class.

Was thinking that I could run gasoline for a while and when its in the budget switch to alcohol. Long story short I'm trying to prevent spending a bunch of money in one big hit.

As far as motor building I guess I worded that wrong. I'm planning to get a used motor and simply do a refresh to make sure it doesn't grenade my first weekend. Im very familiar with sportbikes so u know exactly what you mean Honest Dad as far as getting more power out of them. And learning how to drive first. :)

I'm simply trying to figure out a cost effective way of getting my feet wet in the sport.

I'm excited to see new guys coming out into our class but if you think that this is an entry level club class you will be highly dissapointed... Yes it is a great class to get started racing but you will find that there are some really really fast cars out there. It's a ton of fun and great guys and not discouraging you at all just be aware of your expectations... It's very competitive and you have about 15 guys been doing this for a long time and are very fast and do not see this as an entry level class... Like I said not discouraging you just have some knowledge before you put the pedal on the floor! Good luck to you and most importantly have a ton of fun!

You can run gas without any issue, we did it for years. My first championship and my brothers first were both on gas... Racing against guys who have alky.. The main reason we switched was for safety, and longevity... You can convert most cars for $400-$700 maybe even cheaper in some cases.. But you will be fine with gas to start...

Good stuff. Thx for the advice.

What the best bang for buck Injection conversion for Honda

It should work with any makes, but you'd have to check hyper to make sure. We did the Hyper Econoversion with a Power Commander 5 on our 09-11R1. I know a decent amount of people has went that route. In reality all they're doing is drilling the injectors with a small hole in the ends, but if you go to much they stick open, which one of ours did, we told them they drilled a new one and sent it out. In total I think for drilling and power commander was $500-600.

For us we sent in our 8 injectors had them drilled, bought a power commander 5, hooked it all up, threw methanol in the tank, changed fuel pressure and started it. We started drilling our own injectors now though. We bought the Power commander 5 from hyper and they put the correct tune in it. We went alcohol due to overheating issue because of Yamaha lol. Besides purging the fuel weekly, cleaning the injectors weekly, and running 5 more gallons a night the we did with pump gas I love it. Also we already had a outboard Walboro high pressure fuel pump and fuel regulator in the car, we was told a stock bike fuel pump that's on bottom of the tank would not push enough pressure for methanol.
