Looked good, shame I couldn't hear it on this computer,

How many runs did it take to set it up and get it that quick?

 

[cowboy3669]

not sure how many passes. been an ongoing project for about 5 years with the turbo.

Here's a couple of pic's

Cowboy . . very cool. And what makes it so cool is that you are way out of the box 10.65 is moving for one of these engines. Do you think there's anything else left in it??

 

[kent_in_kc]

Sure but what kind of mileage does it get?

I think there's some more left in it, it has been 10.33. right now I'm fighting wheel spin on the launch.

not sure of exact mileage. the tank holds about 2 quarts and I cannot make two 1/4 mile passes on one tank full.

what is the windscreen on the front? Is that one of the ness fairings? I really like the look

 

[cowboy3669]

Yes that is a Ness fairing. Picked up at a swap meet years ago. Did not have wind screen, new one cost me more than the fairing did.

That's just plain wicked engineering! Nice job, bro.

Thank you.

Any updates?

 

[cowboy3669]

no big upgrades right now. still gathering parts to try to fuel injection.

 

[cowboy3669]

DADDYCYCLES was asking about pic's so instead of highjacking the other thread here is the thread with the pics

 

[plattey]

cowboy3669, mindblowing! was wondering how you fed oil to the turbo? did you tap into the stock engine's oil system? thanks!

 

[Ghetto]

This thread needs more video.

 

[jay760]

What gearing are you running? and what revs are you pulling at the end of the quarter?

 

[cowboy3669]

18/38,had a tach w/telltale would hit 10,000 rpm. the rev limiter has a upper limit of
9500 rpm, have to turn off after launch or hits upper limit at about 1200 ft.

Here is a clip of my 1/8 mile run. The motor is stock with a first over bore. 38mm stock carbs with larger main jet, K&N oval filters and 1 3/4 open pipes. Gearing is 17T with 42T. Easy launch since the clutch gets weak when run hard.
