Boost controller installed. Not sure what it's set at, should be a surprise tomorrow. I did 2.5 or 3.5 turns, don't remember but it has 11 turns total adjustment.

Dyno or not, I literally have 15 miles on this setup, so no I'm not throwing it on a dyno right now. Probably going to learn how to setup a compound boost setup, and fix whatever problems pop up first. Then drive and track it, and enjoy it.

Also planning to track it at 22 PSI and 30 PSI (old SC boost levels) to see how the car's performance changed at the same boost level. Expecting the turbo to be faster of course, but I doubt the 60' will be as good.

Anyone know a cheap thing I can use to PWM the pump? A solid state relay, or some transistor(s) that I can hook up easily/cheap? Emphasis on cheap. I can figure out the MS control part.

Whatever was suggested for the fuel pump PWM, wherever we were talking about it.

A big fet

Joe posted a link to 20,000 different ones, not a specific one that would work though he described one that would work.

You've gotta dump a lot of heat to pwm a 10A load with a transistor.

Something like this is what you need, all premade with extra things you can ignore. This is only rated at 3A, or 6 continuous.

Or some hella relay, was it something like this?

Wouldn't that count as E-Cooling the 2nd turbo?

Sound like a win all around.

Hey Pat, when you get all your learning and satisfaction from this awesome build, I want to see combo #3: Turbo to super charger.

no.

keep the remote turbo on, and then go back to the dual supercharger build.

LOL. At 22 PSI, the Turbo setup is making 20 whp more than the SC did at 30 PSI. Whipple was 350whp @ 30 PSI for reference. Same tune, I have not TOUCHED the maps at all in any way, literally just unbolted the SC and installed the turbo setup.

Oh yeah, up to 22 PSI so far.

I have a video I'm uploading now, 2nd and 3rd with me holding the camera in one hand, shifting with the other...

For now.... Yes they're 3rd gear from high RPMs, no I didn't do 2K 5th gear pulls. I was upping the boost and seeing what affects it had. Thus why power is different for each, those are diff boost levels.

Nice! Looking forward to the video and some spool data. Seems like it's working pretty damn well so far.

Oh yeah, at 376whp/267wtq, this motor breathes up top pretty well.

Maybe I can get the power up to say 500whp and keep the torque around 350? Might help keep the 6 speed alive.
