Since we're already OT, I'll just continue it.
Installed my BA intercooler yesterday, super simple, straigthforward. Charge air temps are 2* above ambient, and I saw a max of 109* at WOT in 5th last night. I think it will be just fine for the S280. To clarify I had a Garrett core ATP intercooler and I was seeing 130*+ temps in 4th / 5th
