I love those old Mr Turbo parts. The wastegate is killer. I like how you have all the parts mounted in the belly. Looks clean! Love the compressor.

Just a couple of small things from the pictures.. Is it an F/F? Did not go all the way to the beginning but curious what you did for a tranny, crank, pistons, oil pickup and clutch. What sort of mods are done to the Mikuni? What are you using for a fuel pump and regulators?

The cyclinder should have been O-ringed with copper. Have no idea why they wouldn't have done this. Assume you double checked their skirt clearance and ring gap.

How are you going to handle compensating the fuel pressure against boost?

You may want to call Terry up and ask him to send you a bowl extender for it.

I used to have a stock street bike (I mean stock!) with a similar setup. One of the funest bikes I ever owned. Could not run real high boost with it being stock but it made more power than I could use in that chassis. Stuffed a little slick under it later on and could melt it at the track.

Hi Lecroy thanks for your comments here are the facts... turbo is a Rayjay F/F by turbonetics,trans is Fast by Gast slight cut with billeted output shaft.pistons are Wiesco 1229 10.5to 1,crank is a Gardner double pinned and welded crank. Carb is the Mikuni from Mr.Turbo and I don`t run regulators. It is pretty much the same set up as my dragbike except smaller cc`s and only 10psi of boost max.

Don`t worry we did it right,I build a lot of engines and they are perfect:D.

No regulator:eek:

Never needed one before :-k should be good.

someone care to 'splain to my uneducated arse? What is an airshifter? Why? And how does it work?


Kid, the airshifter works with air or nitrogen, when you press the button on the bars it releases a charge of air to the actuator (piston) on the shifter at the same time it sends the same charge of air to a solenoid that is hooked up to your ignition and kills the ignition for a split second while it puts the bike in gear. You can go through the gears in seconds with the throttle full open:eek: I hope that sheds some light on your question. Kris.

Do you gravity feed the Mikuni?
If not, are you running the Mikuni and Nitrous off the same pump?
How much pressure does the pump put out?

I'm just looking at it thinking with the four jets in the manifold that as the boost goes up I would expect it to lean out. Most I have ever been able to push against the needle on that carb is 9 PSI before they blow open. So if your pump is 9 PSI for the carb and nitrous and your running 10 PSI of boost ..... Are you counting on the high pressure of the nitrous to make a low pressure area for the fuel and siphon it into the manifold?

Just curious...

Yes it is going on the street and bike shows and back and fourth to work. The stock 1100e frame is a very strong frame and not much strengthening is required,ask all of the drag racers out there:D The swingarm is extended and the suspension is all new and ready for corners,can`t wait!

How about breaks, are you going to update them?


Oh, I'm in SOCAL, not too far of a drive. I'm available if you need any test riders :D

Fuel pump on both, turbo diaphram pump at 7-8 psi,nos pump is a vane type at 6-7 psi

Stock 1150 brakes with good pads.

Thats ok my NHRA license will do just fine;)
 
Ok, two pumps. How is your 7PSI fuel pump for the nitrous pushing fuel into a 10 PSI chamber and keeping close to the right mixture?
 
Don`t know yet it, I have not started it yet. I will cross that bridge if I have to.
 
Crossing the bridge = BLAM; One or two jets right on the intake to the turbo = problem solved.

Good luck with it. Looks like a fun little ride.

Problem,not solved. Can`t put foggers in the manifold prior to the turbo, theres no room due to the fact that the carb mounts to a rubber boot and there is no lip on the turbo housing. It is a flush mount:(. The only way is the intake manifold. Lets think physics here, 1800 psi of no2 and 7 psi of fuel now you can compress gas but not fluid...see where I am going here? No matter how much boost you are pushing it will not stop the flow or even slow the flow of liquid in to the chamber. It work fine and have done it before without a problem:D trust me:eek::-k Also have a two stage timing retard and a pressure switch mounted in the manifold that will adjust timing on the fly. The BLAM comes from the timing not being correct...I don`t know how many times at the strip I have seen bikes go BOOM due to incorrect timing.

Yea, that's what I thought....

You've done it so it must have worked.
 
Looking at all the foggers available now, there are a few that would seem to work like this but many have the fuel mixed outside the jet and the two outlet ports are very far apart. I was going to try an model this at one time.


How do you know timing was the problem on bikes you have seen fail?
 
Most people can`t leave well enough alone. I have seen many people that have a great running bike that is consistent and want more power by diddling with the timing and thats when it happens BOOM:eek:. You can hear it too along with smelling it. I have lots of trophies and championships to prove it:D.

Not sure that proves anything about what is causing someone's motor to fail but I'm sure your right.

We don't see too many bike motors die in E/T here. So far, one this year. Most are cars. Our own die from stress, normally one of the throws gives.
 
It`s done:D well almost about 98%...
