Did you use an inline brake booster 1 way valve?

There is no check valve, the valve is set to fully close above 2000 rpm

I'd suggest using 1, if braking effort isn't up to snuff

I forgot how small the battery is in this truck. I think 5 years is a pretty good run for a battery.

Broke the TKX shifter again. The steel "Z" bar on the match box is all that keeps the shifter from overshooting the shift gates. At least the parts kits are cheap, so I bought 3. When I get to my last set ill buy a short shifter so I won't have to deal with it anymore.

Added some extra A/C vents between the evaporator and the heater core for better cooling. The extra volume makes it cold inside with the windows up and they are the perfect height to blow right up the shorts to keep me cool with the windows down.

This truck is cursed, how the hell does an alternator case break? Its a GM 1 wire from summit that is less than 2 months old.

Never like the CS style GM alternators, they usually have rear cooling issues and the diodes and voltage regulators usually get cooked.

When I worked in retail parts, I saw a tonne of these warranting out even the new ones from AC Delco. The rear housing was made to small and was poor cooling. The CS alternators for big rigs last longer, but they are bigger.

The older SI alternators are much more reliable, I like the 135amp from '85 Cadillac Fleetwood Brougham.

But there are way more reliable alternators from Nippon/Mitsubishi/Bosch for Hondas/Toyotas/Nissians  they make 130amp ones for about $100 usd.

It broke again in only 25 days, Summit took the Powermaster back and sent me a Top Street Performance one. I double checked everything i could think of that would make it my fault. The belt was loose enough to squeal on startup so it wasn't over tightened. The pulley is aligned and square. All the brackets are tight. I i keep being told that the problem is in the mounting but the factory Kia one has been in there a decade. I only replaced it cause the 70amps is not enough to run my A/C.  I redesigned the tensioning bracket anyway just in case. I'm using a SBC bracket welded to my existing one.

Needed to add a 50amp RV plug to power my TIG. While i was at it i got rid of the horrible looking flex conduit to my A/C. I didn't realize the Hobart TIG i got was 50amp cause it had a 30amp plug on it i assumed it was 30. It welded 1/8th just fine while i was practicing but when i went to build up the throttle body mount it just stopped making puddles then popped the breaker after 3 seconds of full throttle. It took all damn day to put that stupid outlet in. 50% of that time was trying to get the 6awg back in the boxes, that shit does not like to bend.

The build up is slow going cause the #17 torch i have gets hot pretty fast. It should be built up and ready to machine by the end of the day.

Trusting the process of welding up and grinding back for the K24/ sportage hybrid intake manifold im making. Im not the best welder so finding zero porosity when grinding back was a huge relief.  Tomorrow I'll drill and tap the holes to mount the 72mm throttle body. Then I can gasket match and smooth the transition into the plenum.

So far I have seen zero holes, no inclusions or porosity. I'm pretty stoked. I figured there would be something after doing over a 3/4" build up.
