I think pressure cap placement has more to do with a high spot.

Or the radiator is clogged on the outside with dirt.

Sounds correct to me. Assuming a cast piston, with detonation, the engine will grenade.

IngersollRand air compressors that use a Cummins M855 (855 CID turbocharged) driving a twin screw supercharger equals industrial strength air compressor.

Aren't coincidences a bitch.

I don't believe cylinder arrangement is nearly as important to torque production as displacement. Heavy duty powertrains use an inline due to manifold advantages with a turbocharger.

That is a road to disaster. I don't think you should.

Potentially it is more than one problem. The brakes being one, that you can not hold at 90%. The compressor is engaged, but the idle up function is not happening. Check your DTC's for a code 51.

Is there an online version? edit: Please excuse the crudeness of the page. It is a scan. This is all Toyota products through 96, OBDII.

Of course the 4.8 and 5.3 are the same family. And the 6.0 was available the same time as the 5.7 LS1. It is a great engine, no doubt.

You know the popular Mustang Joke right? What do 300 hp, 400 hp, and 500 hp Supras have in common? 12 second time slips.

It is probably listed in the factory repair manual. Toyota is typical in an engine speed governor. An old style governor doesn't usually cut anything. It simply all the fuel you are going to get. The ECU controlled cars do cut fuel injection and turn back on.

Yes, it is still called 4th gen from Chevy die hards. It doesnt change the fact that it is a GM product.

It is better to think of it as do you want your torque peak low or higher in the rev range. Not do you want torque or horsepower. I know just about everybody says that, but everybody is wrong.

You and the one you quoted are correct. Torque is the force the engine converts from fuel. Horespower is the work being done with that force. But I digress on the idea that HP doesnt matter. If you have 500 lb/ft of torque at 2500 rpm, like a Viper or something, you can do 238 hp of work. But...

Pull trouble codes. You can buy a generic scanner if you don't want Toyota/Lexus to work on it.

The owners manual does not say?

The ECT button changes the shift schedule. The throttle cable to the trans merely raises line pressure, and the TPS and speed sensor determine shift timing. On a standard hydraulic unit, the throttle cable would raise, delaying an upshift until governor pressure overcame it, and forced an upshift.

I don't have to image boosting 30 psi. Well, on a car I do. edit: I had thought of the 4.7 as a swap for an MA70 Supra. The packaging has made me think otherwise, and I should just stick to the 1UZ. There is a few in the US already.
