Idling while warming up Here.

It’s rich and still burning stuff off, but it sounds good.

Heat wrap on both downpipe and intercooler piping helps a lot!

LOVE IT!!! Big cam through a big pipe and a turbo - sweeeeet!!

Don't let it idle much more than getting it full of coolant. Let the ECM take care of the fuel trims during some test driving.

That is a lot of chop for a turbo car. Mind blown!

It smoothed out a bit once it was fully warmed up and learn kicked in. BTR Stage 1 turbo cam! Duke is helping me with the tune and we need to adjust for the ethanol content/enable flexfuel

I'd like to think keeping each exhaust bank divided into the turbo helps the chop sound. 4" downpipe without any muffler or resonator. Just mandrel bends of goodness.

Thought I had a charging issue, only getting 12.6v out of alternator.

Bought this 145 amp unit:


Looks great!


However:


Still didn’t fix the 12.6v!! 😠

Looked at the alternator exciter wiring: 🤔


It was backwards! Depinned and switched:


Yay for 14+ volts! Now do I return the alternator and put the old one back one?

Keep it save the other for a spare

Its a higher output anyway

That was my thinking; but not sure the hood will close with the larger alternator.

 

[TURNA]

Well close the hood man!!!!!!!!!!!!!!!!

Cutting a hood for an alternator isn't the same as cutting for a forced air device. Just saying..
