Yea Ill see if I cant get back on that same dyno here soon...might be after I upgrade my turbo kit...
The suction cup is pretty strong, I welded on a flat piece of metal to attach it to.
Forgot you had a full-blown race truck, mitch. When are you going to ditch the alt and just use some litho batteries?

I may have the hot pipes modified instead of the driver side feeding the back of the passenger log, have them both combine at the turbine housing and switch to a T6 at the same time with the same turbo, just T6 exhaust housing....thats a few weeks off though 
Summit kicked *** on this one! I ordered the fitting I needed at 6:30 last night and it was at my doorstep by 11 this morning! Of course ran into more issues....those studs, especially the rear ones, are A BITCH to get to! I hope I never have to take this intake off lol. The new fuel fitting fits perfectly behind the alternator and I shortened the crossover hose to go under the intake. I had to extend the wires for the alternator, IAC valve, and TPS sensor because I shoved the harness behind the intake. Not a huge deal, just took time.
The coolant block came out really good I think. I used some plastic spacers to keep it off the intake manifold, so it shouldnt add any heat to it. Also adjusted my meth controller to have a slightly higher turn on point and higher initial amount.
I let it idle and made sure there werent any leaks and everything works great. Drive test comes in a few hours when there will be less traffic. The low tonight is 63! I can honestly say this took way longer than I thought it would, but damn does it look sexy!

Im going to wire a solenoid to my hobbs switch so it is only open when I have slight boost, basically acting as a lower limit to when meth can be sprayed. The meth in front of the solenoid will still be atomized but pressure should drop pretty much instantly so the volume of meth being sprayed when its not suppose to should be very, very small. If I had thought about that before I would have had the BOVs put further back or just put the nozzles in front of the valves again...

Well some driving impressions...
I need to redo my throttle cable bracket. The way it is now the stationary part is way too low below the TB. This means the first part of the throttle (0-20%) is very nonlinear (think cosine of a small angle...) making it very touchy with a high break-over point. Redoing it so it is more level with the top of the cable track should fix this, problem is the cable is just long enough to reach it in the first place. Gonna have to get fancier with the bracket, and hopefully itll still look presentable.
Loss of low end power.....what? Felt about the same to me
Im sure my decent compression and conservative cam (226/226 117) help that out, but the low end feels fine.
Top end....feels about the same. Granted I only pushed it up to about 14psi tonight, but it doesnt feel a whole lot different. I have the ladder on and its incredible how much drag that thing makes at 100+
I need to get my meth situation settled before I really lean on it, and I also have a lot of tuning to do. The trims are wanting to pull fuel below 4000 at part throttle, and add slightly above that, which tells me its working better at high rpm, which is expected. The boost regions are about the same. Also getting a nasty backfire when I let off at high rpm which I think I can fix with some dfco tuning.
So in summary I still need to do a lot of tuning and some track runs to make a final call.
