here it goes guys, been talking about a rear mounted turbo setup on my 1990 katana 600 which would be a blow through carb setup. Alot of ppl say its too hard to tune and to switch to EFI, I want to see if i can do it!
Background, my bike has some mods to it and are as follows.
Full V&H exhaust
poor mans ignition advancer 3-4*
Stock air box with new stock filter
carbs have been rebuilt and added a stage 1 FP jet kit
R6 rear shock with shock extension mount to raise the rear 1.5"
Post 4.5" rear rim swap with 170/60 shinko 011 tires, modded brake arm
Rear pads are semi metallic and new rear aftermarket rotor
Front brakes are stock caliper, EBC HH sintered pads and EBC drag lite performance rotors, All brake lines are braided SS "smoke" from G&J aircraft, billet adjustable CNC brake/clutch levers
Custom gauge cluster and dual retrofit bixenon projectors
Shoria lithium batter and fiberglass solo cowl.
phew! now onto the turbo specs.
G15 turbo with 1/4" steel exhaust flanges.
Braided -4an pressure line, 5/8" or -10an return line to oil fill plug.
Custom steel Plenum with pitot tube (need to make)
custom 2" exhaust from V&H header to turbo with SS vband disconnect and then 2" custom undertail exhaust.
Pressure side will be 1.5" steel tubing to plenum
Going to get 38mm BOV (4psi) and waste gate (4psi) as well as low pressure fuel pump and boost referenced regulator.
Cold air inlet side of turbo will be 1.75" to 2" steel tubing with 52mm POD cone filter on the end.
ALL COUPLERS are rubber from home depot and worm style clamps.
I plan to only run 4psi of boost to help the motor live, and the turbo is good for 100-200hp, a G12 would have been better for the 600 which is good up to 130hp but I plan to swap to a 750 or 1100 down the road so the turbo will work better on those motors. I will be running no intercooler on the 600 at 4psi, but if I crank the boost to 7-10psi on the larger motors i will run an intercooler.
I plan for this to be unique as the benefits of a turbo on a slow heavy 600 kat is slim and will still be slower than the newer SS bikes. But it should be a head turner and unique... plus a few more ponies never hurt
the gas tank will be modded for the new fuel system. I will remove the petock and weld a steel replacement with gasket, two 3/8" lines will be welded or brazed in. One for the return which will to the top inside of the tank and the other will be much lower as the pressure line. Fuel pump will prob be around 3-12psi and pump 35gph. Boost will increase on a 1:1 ratio and be set at 3psi as the starting point.
I will update the thread as progress continues and DEFINITLY let you know if it works or not. Too many turbo threads never end here with information letting you know if they succeeded or not.
Feel free to post constructive criticism.
