Didn't hear from them today, so I'll call tomorrow to check on the status. On a whim, I checked their Facebook page and there's a video up that I'm 99% sure is mine. The car model, color, and visible mods (black intercoolers and intake tubing) match so...? The video isn't the best quality, but if I'm reading correctly it says 616hp and 927tq I'll update when I have more info.

I'm also guessing this is the rear section of the exhaust they built.

Called today and 616hp is the correct number so far, but that 927tq is a false reading (damn The dyno people are supposed to come out Wed/Thurs and look at the machine and hopefully I'll have final numbers on Thursday and pick it up Friday.

Congrats on the WHP, I bet Friday can't come soon enough. I'm looking forward to your impressions of the KC. Overall I know it will be much faster, and almost impossible for you to wipe the smile off your face. Get some sticky tires and enjoy. Be sure to post some pics.

Thanks man, I really appreciate it. You're right about that, I can't wait! The car was already faster than anything I've owned before, ha. Plus, I'm still undercutting the price of a new Challenger/Charger Hellcat by over $10k. It'll be extra special for me since I'm bringing my dad with me to pick it up and have a road trip together back home.
I'll be sure to post some pics.

Did you end up with catless downpipes or 200 cell to 3" exhaust? also what other cooling mods did you install? trunk tank? heat exchange? larger intercoolers? Looking forward to see the setup. Its a challenge to add much under the hood to any V12TT, even worse on the SLs.

I went with the catless down pipes to a SS Gibson muffler with internal x-pipe to 3" back exhaust. Pretty much everything other than the tune was geared toward cooling to keep whatever power I ended up with. The heat generated by these monsters was one of the first things I noticed. I've never had a car reach operating temperature in, like, 3 minutes
Cooling mods:
Meziere Water Pump
Speedriven Intercoolers
Kincaid Performance Killer Chiller (and delete HE)
Weistec trunk tank
Modified 180 deg t-stat

Dyno run to get torque #'s. Lower hp#'s than video. They said they had wheel spin problems.

I like the beefier oval tips.

So after a bit of driving have you found a bit more comfort as to what speed you can roll into the power? Have you done any real data logging? I should but don't... I'm curious to see how the car maintains boost in the higher RPMs. Please share anything else you find. Also, what keeps it company in the garage? It looks like an early 70s GM with no side mirror? LOL

Sorry, it's been a while since an update. I haven't done any data logging, but am curious to see as well. I'm new to that side of it. It's officially my wife's car so I don't drive it too much. I do take it to work every other week though which is a 180 mile round trip. I made good time last week pacing a new Mustang that seemed to be in a hurry. BTW, the wife doesn't like the exhaust sound, so I'm thinking either a Vibrant Ultra Quiet Resonator or the Flowmaster Pro Series Laminar Flow which looks interesting. Oh, I've also been in contact with Joe Kincaid and he feels our 180 amp alternator should be able to handle the new stand alone Killer Chiller kit. Good eye on the other car in the garage, it's a 1971 Buick Riviera. The poor thing is neglected as it's too low on springs and needs either airbags or taller springs. Honestly, I'd like to get rid of it, but not quite enough to list it.

For the right price, I'll cover the shipping to NY. LOL I have always liked the boat tail Rivieras. Looks like a beast, it would be unique platform to do a resto-mod. I agree suspension would need to be one of the first things to address.

I recently purchased this car at auction. It's a nice car. I would love to get the dashdac and would be happy to pay you for it. Also would like to know if the current tune on the car is the stock tune or the Eurocharged one. I live in Memphis.
