Jnimbostratus Street Fighter Project

I like your placement for the turbo.  I think a nice setup would be the traditional draw thru turbo location but used as a blow through.

Can't wait to see this one get going!

[jnimbostratus]

because i like to measure 5042 times and still cut 5 times before i get it right. the mock up stage for turbo mount i am being very particular about. being that everything needs to be fabricated around the turbo i want it to be in the most efficient location.

How's the clearance between the turbo and rear wheel on full suspension compression. It's surprising how much the wheel travels under normal riding.

I'm wanting to place the turbo in the lower front of the motor, but, well, it's complicated.....

I've never been a fan of putting something that hot under the seat and near the fuel tank, but it's been done for years.

Another concern is turbo lag - seems that placing the turbo closer to the exhaust could spool it quicker, but so much is based on pipe diameters, ect.....

Good luck and keep those pictures and progress reports coming!

[jnimbostratus]

in this project im not concerned with turbo lag, i welcome it somewhat. if the boost comes on a little less aggressivly im hoping it should help reduce wheelspin. and i hear ya about caution with hot turbo placement. with my bike im not as concerned considering how little there actually is in the rear of the bike. and there will be a considerate amount of heat proofing to protect the seat. but also the further the turbo is from the motor the cooler it will be.

Looks good but will the turbo work there,wont there be to much heat.
I have never turbo charged anything but im not dead yet.I like it keep at it and work out any bugs as you go

Air is a GREAT insulator. Id imagine it would take a lot to get the seat hot.
Turbos on bikes dont have a huge load on them like they do in a car or truck.
And cars have much less airflow over the turbos.
He will be hard pressed to get that turbo hot enough to worry.
Plus, some heat wrap on the pipes, and a heat shield under the seat pan will cure any issues.

Im pumped to see how this turns out.

Whats the most power someone has put through the bottom end of an FJ?

I own 2 turbo-charged vehicles. Both have heat shields over the turbos & extra hood insulation from the factory. My Dodge/Cummins pick-up truck was from the era where Dodge had a problem with the primer lifting off the hood & the top of the cab making the paint let loose & peal. The paint failure started directly over the turbo-charger & progressed from there.

You will want to use a heat blanket to wrap your hot-side of the turbo & its hot-side plumbing. Not only will this protect the turbos surroundings, it will help prevent heat loss in your exhaust feed to the turbine. You want that heat to make it to the turbine for full performance.

Good luck, I've always wanted to ride a turbo-charged bike. Any idea how much boost you are shooting for? Will you be incorporating an inter-cooler?

I double posted somehow. Please remove. Thank you.

i will be starting at 8 psi no intercooler at first maybe add one in the future after i build a motor to support more boost. i would like to find a 1200 motor to build on the stand while i ride the bike with this motor in it.

[jnimbostratus]

if there is anyone in the upstate ny hudson valley area or surrounding area with a 1200 motor for sale or an 1100 with a solid trans for a reasonable price let me know. it what i need to take this bike to the next next level.

[motohorseman]

I'm hoping to pick up a 1350, it's already got a turbo manifold installed via  a spacer/adaptor plate.

Watching this with great interest

I would try to include the largest intercooler that you can, if there is enough real estate up front. I replaced my Buicks intercooler with a much larger front mounted (in front of radiator vs. behind) intercooler. It helped me survive on pump gas premium at 16lbs. of boost. The car is capable of approximately 28lbs. of boost from my research, but you need to run some high octane race fuel to prevent detonation.
