SAFC in my opinion is not sufficient, there is no timing control and very limited fuel control.

Did I miss what you're tuning it with?

OOBE won't reply...he hasn't been active in over a year.

I disagree, but that's OK.
He already lives in Bahrain, which gets rather warm in the summer and stays pretty nice in the winter.

100F average summer temps PLUS a turbo ontop of an automatic transmission dumping heat into the cooling system. He'll likely want to add more cooling capacity, especially if he's running a front mount intercooler which would be dumping warmer air through the radiator. If he gets an aftermarket radiator then he HAS to run an auxiliary cooler since there won't be a trans cooler built into the radiator. Regardless of that, the stock trans cooler is mighty wimpy. Calling a cooler is a misnomer, it's a heat exchanger. It warms the fluid faster when it's cold and keeps it from getting entirely too hot later, however since heat is the biggest killer of the automatic even the 210-220 F coolant temp is a little on the high side for an auto trans. Add atop that 30-50FT/Lb's more torque to a trans that's old already and you're going to add stress and heat that maybe it can handle maybe it can't, it will work it's best at about 180F fluid temps. I suspect in the heat there with the added power he'd be seeing fluid temps north of 230 and that's where things start to degrade.


And about the valve body work, at stock power levels the A245/A246E have a slow/weak shift from 2-3 right off the bat that gets a little worse as they age. Slow shifts are slow because things are allowed to slip as they apply, slipping is friction, friction makes heat. Adding power to a slow shift will just make it slip more because of a weak apply. Correct the 2-3 shift softness and it'll help a lot. Other than that and the general compromises that Aisin makes between shift speed/firmness and comfort (which are inherent to any trans for the most part) the A24x series are solid units.

no he wont, not with low boost.

You will NEED an auxiliary transmission cooler to allow it to handle the extra power, if you can find someone who can rebuild the transmission and modify the valve body for better faster firmer shifting that would be very good as well.

search "OOBE" in the search bar in the top corner.

he is one of the first 7A automatic turbos on here.

go for it my friend.
