Here is IJ reply to my question on oil pressure loss under braking at the limit of tire adhesion:

Hi Eric, Thanks for reminding me... I'm running the RX-7 full oil cooler. It uses a thermo pellet design (on upper hose connection), starting to lift off the seat at 170 degrees F., and gradually opens as the oil temps rise. It is a two pass design that maintains pressure in the oil cooler...

I thought so... I looked at the spec sheet just now, he didn't put in a V shaped baffle. Thanks, IJ

At the track yesterday, several racers noted how well the car scrubbed speed while braking hard before a corner; I'm talking about going from 110 to 50 in one hundred feet on turn one, then in another 10 seconds in turn four, from 80 down to 50 in under 100 feet, and lastly, another high speed...

Good and simple solution. I'll try that next time for added assurance that there will not be a precipitous drop in oil pressure. I may also need to go to an AccuSump type set up? I currently have one quart in the oil cooler and hoses, then another seven in the motor. I'm asking questions and...

At the track yesterday, several racers noted how well the car scrubbed speed while braking hard before a corner; I'm talking about going from 110 to 50 in one hundred feet on turn one, then in another 5 seconds in turn four, from 80 down to 50 in under 100 feet, and lastly, another high speed...

I'm almost embarrassed to admit this... Just moments ago at 10:30 this AM, I noticed that I forgot to hook-up the one gallon, coolant surge tank hoses to the coolant radiator. Geez! I'll have that done and tested next week. That all needs to be tested again at the track, to see if what it was...

One word: OMG! Well, that's three... Firstly, driving the 3300 Lbs Supra around this very fast track is also very fatiguing. By the end of five, 30 min sessions, I was done! I was in a Kirkey Aluminum Road Race seat, strapped into it by Schroth five point harness, so I didn't have to fight the...

I'm still planning on having the dump recirc'd, but down stream, where the down pipe meets the cat at the flange, just to make it less noisy and so we don't have to smell the exhaust!

As advertised, the 7M is now more willing and responsive than before the DDP upgrade. Still, I like my exhaust to be more tucked up under the car, so back in it goes for fabrication. Here are shots of it as it is now: Here are two of the DDP: The only time it's louder than the old exhaust, is...

I took the Supra in to VIP Performance in NE Portland, to get these two items placed where they can do the most good... Some minor fabrication is needed to be done to the DDP to get it all to fit up there the way I want it. An additional bracket to fasten the DDP to the transmission is planned...

Hey "Spain, If your Supra is otherwise drivable or, even if it isn't, take it to VIP Performance in Portland; Wryann is more than capable of tuning your car as he has mine. Wryann is well versed in our TCCS and has knowledge of Vf as it applies to our ECUs. He tuned my Supra that has an AFC...

I called TAP Plastics on the question of using a defroster with Lexan plastic; they do not recommend it! It may cause the plastic to deform over time.

Well, the eight year old exhaust system has a hole in it, is rusted, and the catalytic converter is broken... Time for a new exhaust. I ordered a new one of these: The DM 3 inch exhaust will work nicely with the BIC DDP that is on its way. Plan is to have them both installed on June 14th.

Update on the Supra's weight: 3364. The shop (VIP Performance), corner weighed it to get the total weight. They only managed to get the weights to w/i 15 Lbs a corner, so they are recommending coil over suspension the next time it needs springs or shocks. In another vein; I had the alignment...

I've been going back and forth on ditching the rear window glass, wiper and defroster for Lexan. You know, the visibility out the rear is bad enough the way Toyota set it up... Can Lexan take the heat from a defroster?

I was thinking of getting a lighter spare tire for the Supra... but I decided I needed to lose mine first!

At this time, I'm planning on replacing the rear glass w/ Lexan and ditching the rear window defogger and wiper. Also, the radio antenna. I could ditch the spare tire, but where I drive, often there is no way to get cell reception. The next lightening will be to fab up Alum bumpers. Sound...

Here is a what I've done so far to lighten the Supra: 1. Alum flywheel, pulleys, intake, radiator, smaller, lighter alternator, drive shaft, bell housing front plate, drive shaft loops 2. Cut out front bumper, removed, air conditioner compressor, power steering pump and all the plumbing for...

I'm looking into it, though I haven't decided to spend the money it takes to purchase one. I just can't justify the expense to myself... What is the weight difference between a CF and stock hood? That is what I read here on SM. I also read that I can save a lot of weight replacing the steel...
