    Very very noob question

    Boost will vary with load, most Tubo cars struggle to hig the wastegate in the lower gears, this is why they're ofter faster with lower numerically Diff gears, i.e. NA cars run 4.3:1 and the Turbo cars are either 3.9 or 3.7:1 as it loads up the lower 3 gears more making more boost and offsetting...

    Engine overheats on highway with AC on

    Nah no harm done, Gary is a Crotchety old fart like me, he somehow avoided being roped into trying to herd cats here (Moderator) I sadly didn't ;) He is however one of the more knowledgeable guys on Supra Mania and over the years has provided brilliant technical assistance to members, I can...

    How hot is considered overheating?

    Some comparative readings on the intake side of the head might be more useful.

    Straight 30 oil for break-in

    Have paged JDub, he's the best man to decipher all that ;) (my take is there's no friction modifier in there)

    Straight 30 oil for break-in

    Do they have a web site with tech sheets? (it would normally say on the bottle if they're in there) The Valvoline "running in" 30 wt has had a name change to "small engine oil" recently, had me scratching my head for awhile.

    Engine overheats on highway with AC on

    As I said earlier the tray is good for about 5c difference at highway speeds, IF a cooling system is marginal it might be just enough to tip it over into H... Marginal could mean blocked/bent fins in the Rad or AC core, partially blocked tubes in the rad, erroded waterpump impeller and or...

    As long as it doesn't have any Friction Modifiers it'll be fine.

    Engine overheats on highway with AC on

    That and a Block test kit would be my first step in diagnosing this. Buy some big diameter stainless steel washers (minimum 1 inch with a 6mm hole or 1/4", also 12x m6x 1.0 pitch Stainless 20mm long bolts to hold your new tray in and reduce the chance of trashing it in the furure.)

    Can I bore 0.060" over?

    Sorry don't have any minimum thickness data to share, it's a bit of a gamble at the best of times, back in my SBC days once you got to +60 you started having some weird overheating issues using the same non overheating hardware from before the bore job.. Even getting a heavy GTE block may be...

    Adjusting boost?

    Early morning Logging run 25+ psi with a GT3540R and slightly damp/misty road, log shows the "Ohhh SHIT" moment where it burst into wheelspin at 100+ Mph rollon... (I think wee came out) This was before my DBW Trac setup, I also have logs showing wheelspin over 100mph on a bone dry road so...

    I had my Boost control tied to my Traction controller, only time I changed it was on wet days.
