Ceramic thermal coatings are the best for your exhaust system. They hold up to the temps, and they limit corrosion issues. (Inside and out if you have them coated right.) I've coated everything except my HKS cat back... LOL, it just has some 1600f high temp paint on there, and has been...

Gas mileage is directly attached to boost levels. :) More boost, more fuel. Also your state of tune really comes into play in how well your car runs. IF your running rich to save the motor and run more boost, your going to get crappy gas mileage. If your O2 is bad, same deal. Plugs, wires...

If the new one is anything like the old one, any wideband will work that puts out a signal the Eman can calculate off of. You determine the parameters. I had my PLX hooked up, and programed into the Blue Eman, and it was dead accurate with the readout on the PLX. (Used the voltage to AF...

The pumps I was talking about are to pump the Toluene from the 55 gal drum, to your 5 gal gas can. I would attempt to pump it straight from the drum to your Supra, as this stuff is paint thinner, and will eat your paint off pretty quickly, or at best, only stain it if you spill some. I use...

I already have, and use the pressure sensor with the blue Eman. So, I'd just need the new 14pin harness, and could hook up the PLX to that, and allow the "ultimate" to revise the map based on AF at any combination of RPM and pressure? Sign me up, this rocks. Anyone want to buy a blue...

That RB with the SC and twins is pretty nice. :) Looks like a roots type blower, and those turbo's are not very small either. (Would be interested in seeing the power/dyno results from that motor.) You could run some seriously low CR, and still be driveable on the street with monster top...

Compressed air, possibly might work, using water to force a "3rd" impeller inside of the CHRA? Don't see that happening any time soon. (Unless you have a custom cast CHRA made up for this turbo. Then where are you going to get water under pressure to spin up the turbine? This is going to...

Very interesting. Hope it wires up the same as the blue. The auto AF deal sounds nice. It's great that it works with my EO1.

Let's put this another way. If you want a gear driven setup, your going to need a motor right? (Assuming you can build a high speed clutch that will not cause shaft problems with the turbo balance and other issues like machining the CHRA to accept all this stuff.) Where can you find a simple...

To give you guys an idea of how much the toluene has varried price wise, it's about 5.00 a gal now, and was 1.04 per gal when I bought two 55 gal drums two years ago. Ouch. Word of advice. Your going to need a pump with Viton seals. (Plastic pumps seem to work best, the simple ones last...

Most 89 models had the EVO part of the steering rack. (It changes your ratio, or the amount of power assist from what I'm told.) 88 and older is a more basic rack and pinion unit.

Compressed air is easy to get. Just add a small electric compressor and tank setup. It runs only when the tank pressure has been depleted. (Pressure switch) It would be running when your not boosting, so there is little drag on your motor. (just alternator) Also it's easy to setup using...

Looks like over 40 Supra's, so this should be fun indeed. Good break in drive for the car.

Not to get too technical, but here is how it works on an Otto cycle engine. (And why octane matters.) Intake stroke: Piston generally is going down, this creates low pressure, and the open intake valve allows air/fuel in the manifold to be drawn into the chamber/cyc. (Or in our case...

Who left? Guess I've been gone awhile, but the last person I know of that "left" was Mellow deciding to sell his car and go with a Viper. (No problem there, but his experiance with the Supra will be missed.) I agree, this is the net, and people tend to be much more nasty sometimes than in...

HP readings are slightly optimistic, but the other readings are pretty dang close from what tests I've seen in magazines. I think C&D did one here awhile back, and G-Tech was rated pretty well. (Just about as accurate as the ones costing thousands of dollars, and really, if the data is...

Did the gpa motor have larger valves and port work done. (IIRC, it did.) Any photos of the head and combustion chambers? I ported mine, and smoothed out many of the sharp edges on the chambers to reduce places for hot spots to occur w/o killing the squish areas. Also un-shrouded the valve seats...

I ran on stock internals, even the head gasket (Retourqed of course) to 18psi and 240rwhp for quite awhile. It was fine untill I boosted past 20psi, and detonated some, that took out the HG, and later on the same motor, boosting too much fried the pistons. (However, I'm starting to wonder if...

That must have been it, crank v/s whp. (With a 15% loss, 700 is 595rwhp estimated.) Still a crap load of power, and the tourqe must have been pretty good too. (If it was anything like the stock CT powerband.) I know the cams would move that around some, and the "modified" CT26 had to be...

LOL, that's under 700... LOL Heck, even 560 with a small turbo is going to be pretty dang fun. (I have no idea where mine's at right now, but it would be nice to see 560 on this turbo/fuel etc.)
