That's actually a line I stole from another long time member here and good friend Hilton. He got me started modding fbodies, and consequently helped put the first cam and converter in this car, a TR224 and an Edge 3200......Welp one driveway burnout and that same flex coupler broke again. I have ordered some Vibrant slip fittings and some ICT Billet solid billet motor mounts. Hoping this will solve the issue of the hard mounted turbo......or something else may break. Either way this is an aggravating learning experience. The yukon 60e decided to break the sprag again. (I love fixing the same **** multiple times). So I have a broken tow bitch and broken race car HA! 80e swap and BTR cam coming for the yukon (insert evil laugh). I will link that thread soon when that gets underway. Only 2wd 80e Yukon denali that Im aware of?? Should be sweet.

Yeah I have those same solid mounts on my cars and they fit perfect. I got tired of messing with charge pipes separating too and got some real nice flexible v band couplers.

Dyno day.
Why does one pop the hatch on the dyno? Funny you should ask that.......
Similar to my last track outing the car was going lean above about 10 psi. It made around 525hp letting out early. I pulled the fuses on the pumps and sure enough one wasn't running. The dyno operator was kind enough to let me run home, grab a spare pump, and swap it in on the dyno. All was well after a 20 min repair, and both pumps were up and running. Made another pull and she made 575hp. Still looked a little lean. Added some fuel to the VE but i was suspicious because the injector duty cycle slope wasn't linear and they were showing 100%, which wasn't right. Took a little timing out, added a few pounds on the boost controller and made another rip. Made it to 630hp @ 5500rpms before i let out from AFR creeping/jumping up. At this point the injectors were at 120% duty cycle. Checked the pumps again and the same side (brand new pump from Summit) wasn't running. Called it a day before i hurt the motor. On order is a Magnafuel 4303, fittings to convert to a -10 feed, and a generic sending unit since the E took my stocker out and i have no working fuel level gauge. For those wondering it is a chris1313 drop in twin kit with his hotwire kit. Both pumps are powered and grounded at the same location. This is no dig on him as his stuff is proven, and everything seems top quality. Not sure whats going on, but regardless we are gonna swap it up and return to the dyno hopefully with the issues sorted out. For those wondering about the power curve, i realize a dyno isnt the street/track but the curve builds like a mountain with no torque in sight.

New pump.
So I built a siphon top for the fuel tank. It pulls fuel from the lower bottom of the tank, and I've seen these for sale for other cars for running an external pump on a stock tank. My mistake is I welded a -10 fitting on and -12 is recommended. So we will call this one temporary. I also want to figure out a way to make this generic float work so I can have a working fuel level gauge. In the meantime its running with this setup. The pump is slightly loud, I have it mounted on the rear framerail by the trans coolers.
And just for fun.
