Topic: intek single upgrades

[iused2mow]

Hey i am looking into a engine that is going to be put through some tough love. I havent heard much about the inteks but i know where a few are. I was wondering if they had the weak crank problem on the i/c ohv motors? And are there any aftermarket parts for them? Are these motors pretty strong? Strong enough to hold about 6 psi of boost?
thanks agian Zeth

Boost?      Sounds like fun, first thing I would worry about would be the cast pistons.  THey do not like forced induction!  But, i'd imagine with proper ignition timing (retarded) , sufficient fuel supply, a colder spark plug , and maybe some alcohol/water injection. You might have a mean little motor that will last longer than a couple passes.   Are you building a custom supercharger?  Or have you found the worlds smallest turbo? LOL  Keep us posted, sounds like a fun project.

ALL THROTTLE, NO BOTTLE.

see that is the only problem. I am looking to get an electronic turbo, something like a blower motor to have variable boost on push button setup i am looking for a strong but cheap motor to test on. i am going hunting for one this weekend

I have thought about trying a turbo engine build this winter if I have time to run in the open class at a local outlaw track just to see if I could make it work. The main problem is on a small track you would just start to build boost as you got to the turn. If you could figure out how to keep you rpm's and your boost pressure up by clutching in the corner I think it would work. Belt style clutch definitely would not work!

see i am talking about a blower system this is gunna be on an experimental build that i am gunna try to get a speed record with. I dont know if i am gunna beat it or not but i can sure try. For track use i wanna try to find a tec ohv or maybe a briggs

"electronic turbo"  boost always there,
 use bypass at carb,
to devert boost air ( to cool engine ) when in engine wind down for turns.

Electric blower/supercharger=Garbage , waste of time and money.  The amount of air required to create "boost" for a 28+ci motor is MUCH more than you think.

Finding a small enough turbo to work for your application will prove expensive and involve a lot of fabricating and time.  Also you must consider with a turbo charger you must cool the turbo and keep it lubricated.  Mowers do not have oiling systems capable of feeding a turbocharger nor do they have a cooling system.  You could always go with a ball bearing turbo which is quite expensive.

Your only option,  unless money is no object, is to pretty much build your own supercharger.   What you need to do first , is  some homework on the subject.   Why reinvent the wheel?  Find out what people have built/ experimented with.     I'm sure you will find some interesting, budgeted projects you can "base" your design after.  You're probably only a couple mouse clicks away.  good luck

OK GENTLEMEN we been this route before no mower racing association allows turbo charging and we are not gonna waste space discussing doing it here. That includes nos or any other type of boost. ALL naturally aspirated here, Got it.
