keeping the hose between the turbo and the carb hat from blowing off, I need to pick up better clamps.

The clamp isn't the problem (been there, done that), you need a bead rolled into each end of the tube.

I’m reading this to my 15yo son and he is smiling ear to ear thinking about the possibilities with his 72 318.
Good work and results!!!

Once I read your response Jeff I realized that a bead makes perfect sense, thank you.
Greg, I file fit the rings and opened them up to .035+. All the pistons I have hurt have been destroyed by detonation. One set broke Every skirt off every piston. I'm still trying to figure how it can rattle a piston that hard in a properly clearance bore
Sometime this week I'm going to try a 750 Eddy on it.

Wrist pin offset. It's great for preventing piston slap in low performance engines but...

Yep, that was me the funny sounding guy. If you've ever seen the movie "Fargo" some of us really do talk like that. I grew up and still live about 50 miles nort' of Fargo. coffee

Anyway, it was at 423.1hp&517.4ftlbs@4152 rpm and still going straight up. Boost was at 15.07psi.(I should add that all pulls were done on C14)
I'll have to rewire the phase convertor and pick up some better clamps before I explore the outter limits of the 318.

What size rotary convertor are you using for the dyno and what type of dyno. I recently got a 20 HP motor to build convertor for my SF 901. I may try a 7.5 HP to run my machine shop I'm setting up as I don't think the 5 HP I have now will run the CK 10 properly, I'll find out in a few weeks.

The phase convertor just runs the motor for the water pump that feeds the absorber. It's a bank of capacitors that kickstart a 3 phase motor. I've done the same thing just spooling up a 3 phase motor with another single phase motor.
The dyno is a L&S 13" dualrotor water brake. It's good for 2000 ftlbs of input torque.

Well I finished testing and tuning. The motor is still in one piece and ready to go back in the truck.
I'm a bit disappointed as I couldn't get it past 520hp and 633ftlbs. The wastegate and blowoff valves wouldnt allow me to go any higher.
I backed the boost down to 14 lbs. The 600 Eddy made 376.1hp@4390 rpm and 459.5ftlbs at13.9 lbs of boost. The 750 Eddy made 409.5hp@4587rpm and 485.7 ftlbs. at 14.04 lbs of boost.
To get the carbs rich enough I ended up removing the secondary jets entirely. I could have drilled and tapped the airbleeds to richened the carbs up but I'm running out of time to screw with it and this worked.
I made about 35 pulls and probably could have made another 35 but there comes a time to say good enough. So the motor went from 229hp naturally aspirated to about the same level as a 413 maxwedge with a little help of a cheap Chinese turbo. If at some point I feel a little 'gamey' it's just a spring change away from another 100hp.
