Any updates? How was dyno day?

Well, Dyno day has come and gone. We had to reschedule and the next open date was July 22nd lol. ugggh. We had an issue with the BCM communicating with the ECU and my Keys.

We found out through a friend that was programming the BCM, ECU and keys, after the fact that the 2012 R51 BCM had an iKey( who knew the Pathy was a push start that year) So, had to get a 2006 R51 BCM with autolights option and send back with keys and ECU to get reprogrammed. That cost us a month or more.

Finally, it started right up but we heard a lot of chatter from the rear of the Supercharge . It was determined to be a bad bearing on the jackshaft. So, I order parts and get them in last Wednesday. we ran out of time to safely make sure everything would be good to go for dyno day.

At this point, I will be sending off the unit to a company for inspection and rebuild. the blower only had ~6k on it. I am exploring a few other options with the rebuild. We ran in to a couple other issues that are being worked on as wel .

Will keep y'all posted on the updates!

Dude that sucks! Custom stuff and mods are great when they work out, they downright suck when they don't (or until they don't). Eyes on the prize!

So, had to get the blower sent in and inspected due to a bad bearing on the jackshaft. Upon inspection, we learned that the jackshaft had to be replaced as well. Ugggh. Try finding that for a blower that has been discontinued lol. Got it shipped out and off to Stiegemeier Porting Services in St. Charles, Missouri.
The aftercooler (first photo) was sonic cleaned while everything that could be, was sonic cleaned and aqua blasted, all three pulleys were replaced and upgraded, high speed Koyo bearings installed and rotors coated. While it was there, I decided to get the blower unit refinished in black and the lower intake aqua blasted to get that nice machined look. I think it'll have a nice contrast. It'll get shipped out tomorrow or Tuesday at the latest and then back on the motor. Not too much longer.
Hope to get some final assembly photos tomorrow

Dyno day is this Wednesday. @drivendesire working overtime to get this thing done :)

Just talked to the tuner and so far, the numbers aren't quite what we hoped for at the wheels. He said it's doing 375whp but thats with 35s. Brennan had stock Titan wheels and tires on at the time of his dyno (385/420). of course,, you also have to take in to account the 20 to 25% drive train loss. I see a re-gear in my future lol. I'll update you with final numbers when I get them

Tuner also said that another option we could do would be to advance the timing another 10 degrees and melt the pistons. There's always Plan-B
