Any updates? Can you tell I'm hooked?
I've been chasing down gremlins for the last week. Part of building a cool custom one-off build, is putting up with the unique challenges of a custom one-off build.
I have an annoying belt squeal when it's cold. I thought it was a pulley at first, but I'm pretty sure it's just the REALLY long belt itself. You can only get the belt from Whipple because it's so long so I can't swap to a better quality Gatorback or anything. So Whipple sent me a replacement belt under warranty today but won't get it for another week.
My custom exhaust system was completed. But then I had problems with it. I've got an electric cutout right after the Y-pipe that allows me to switch between two different sides of exhaust, one for the Sleeper quiet muffler, and one for a 3" Flowmaster which dumps at the rear axle. Worked great for 50 miles, then somehow the cutout got too hot and fried the solenoid, and as a double whammy, the exhaust dump melted a rubber boot on the rear axle. Doh! So it's back in the shop today getting the exhaust fixed, and rear axle boot fixed.
On the brighter side, I was able to tow my Mustang and trailer to zMax Dragway on Saturday successfully! The truck can still tow but any kind of throttle and it tries to go into boost, and intake temps go up to 140+ on a warm day even on interstate. I'm using my Xcal3 to monitor what's going on.
Soooo... I ordered a larger s/c pulley to drop the boost down by about 3-4 psi for towing. This will also help with trying to figure out the tuning as well as be able to leave the Wendy's parking lot without using 1000 hp to pull out in traffic.

: There's so little info available for tuning that 6r60 trans and it doesn't want to apply all of the torque from the motor for some reason. But pulling out in first gear, if you stab the throttle to about 30%, it will blow the tires off! Love it!
So with the new pulley, it will only make around 10 psi but that's just fine for me, because it's looking like it's going to be making 500 rwhp at only 10psi. We can raise it back to 14 psi later once we master it on less power.
Oh and I definitely SHOULD have gotten the TSB fixed first for the 4mph bump on the downshift from 2-1. I was lazy and didn't go get it done. The new motor and tuning, makes the bump amplified. Now it's really annoying. Have to get that worked out as well.
Wish me luck, as I'll be back at zMax Dragway this weekend to race the Mustang in Pinks All Out. If anyone's at the event, stop by and see the truck, and say hello!
How's that for an update!?
