Can someone ID this for me? Is this driver side or passenger side oil cooler?

How many lbs of boost are you running?

Power measurement also depends on the dyno. I tuned this december and got 400.08whp on stock twins at 17psi but that probably reads higher since it was a dynojet , and basically i have the same mods.

Streetport, PFC, full exhaust, hks twin power, hks intake, custom IC, rewired Supra fuel pump and race gas mixed with pump fuel.

IMO, as a lot of others', the first thing to make sure is that your car is running safe and cool enough. Water and oil temps are THE biggest issues I've found. After 25 row Sakebomb dual oil coolers and a Koyo rad w/ M2 large SMIC, it's now safe... or at least it should be.

Second, it's important to be able to control even 290 horses at any circumstances, which actually isn't easy at all. Without skills and traction, 290 WHP won't mean anything at all. - Not saying you don't have them, but just mentioning since I have no idea what you got.

This is a really important point. You might be a really skilled driver and this may not pertain to you but the FD can be a handful in stock form. My car is nearly stock, probably have 275 at the shaft. Traction is an issue in 1st and 2nd. So easy to lose traction when it's wet or on cold slick asphalt.

the car is going to boost more when its cold because of the air being more dense

This.

I broke my tires loose for the first time on these tires last weekend driving.

I broke it loose in SECOND gear and I only have approx 280rwhp. I have 275 in the rear too. It felt awesome.

Damn I need more power. Or a v8 haha

So, I finished my first track day last Friday at Autoclub Speedway (California Speedway). 4 Sessions at 25 min each session. Car saw .90 kg/hg pressure at peak on the PowerFC. After the last session, water temp got above 220F. I guess 2nd oil cooler is in order. Car currently have Earl's 25 row oil cooler with -10AN lines and 170 thermostat. I will be ordering a second earl's 25 row oil cooler and connect in series. Car drives awesome except coming out of corners, it's keep on getting lose. I contribute that to the nut behind the wheel and also 5+ year old tires...:)

Looks like you could use a low temp fan switch and some ducting. Another OC isn't going to drop your water temps. 220+F is not ok.

Low temp fan switch was on...:( I think next thing to do is remove air con especially the condensor. I am not sure what ducting would I need, right now there is duct for intercooler.

Some guys using the MazMart water pump upgrade report running too cold. Maybe that's a good bet for you.
