I've been doing both of the above
Major changes in the setup. The supercharger needs a rebuild and since I plan on spinning it way faster then the max rated rpm I'm certain that it would have only lasted a short while. I don't want to half-a** the setup because it doesn't justify the money and time setting up the mounts and pulley system will take. Making that decision took a lot of my motivation
Thankfully Dylan is always asking to work on the car, he rocks - nuff said.
So I've been driving the car around NA for 2 weeks, it's nice to be driving her again. But NA = GAY in my book
So I got a "new to me" exhaust wheel and shaft assembly for my TO4 and have been getting it pieced together. I did have a Garrett rebuild kit on hand from a previous project and I was able to use a newer cartridge from a different turbo. I just need to clean/shine the compressor housing and finish the assembly process. It's gonna be pretty damn laggy though, TO4E, 60 trim compressor, .81AR exhaust housing. I've had this turbo on here once before and it reached full boost by about 4800-5100 rpm. But I had 6-8 psi by 3200-3500 rpm. Large turbo's put out a small amount of boost fairly early and then "flash" spool and hit full boost extremely quick once the motor is flowing enough exhaust to get the exhaust wheel really moving. Think of it like spinning a fan with your hand as fast as you can, you can feel the air it's moving. But when you throw the switch it really moves the air. The flash spool is actually just like that IMO, you go from 8 psi or so to whatever your max boost is in about 1.5 seconds. I ran 20 psi previously with this turbo. It was like going from 200hp to over 350 right now
You want to be going straight when the turbo spools up though or at least prepared to change directions with the quickness. I'll only be running 15 psi at most this time though
I need her to hold together and I'm not rolling the dice again. Although the last failure didn't happen from making to much power, I lost the oil pump on the highway. That never ends well
The manifold is from the JGS DIY kit I bought 4 years ago. I had to cut off the T3 flange that was mounted on the top and weld a T4 flange on the side. The T4 won't fit under the hood if it's top mounted, so I had to go with the side mount. In the side position it damn near hits the strut tower. Not that I'm afraid of "moving" it back some with the old air hammer
I'll have pics loaded today, sorry for the long wait
Everyone that comes to Omaha will get a free beer :fistpumping:
