He did for years. But I haven't seen him around lately.

The pyro. is mounted post turbo, so what do you add to the egt reading to make it an accurate one?

[/ QUOTE ]

It depends on numerous factors. In a nutshell, the post-turbo pyrometer is almost useless. The pre-turbo redline is 1,250 per International engineers, or 1,300 per some gamblers. The post-turbo EGT can vary between zero to more than 400 degrees less than pre-turbo. So to be safe with a post-turbo pyro, you'd use 800 or 850 as the red line. But then, most of the time, you'd be leaving lots of horses in the stable.

So as Wonderhoot recommended, your best bet is to move the thermocouple to the exhaust manifold then use 1,250 as the red line.

65-70 MPH is about 1800-1900 RPM, sound like 3.73's?

[/ QUOTE ]

With stock-size tires and a calibrated speedo, 70 MPH is 2,000 RPM with a 3.73 rear end, or 2,200 RPM with a 4.10 rear end. All '99-up SRWs came with 3.73. '99-up DRWs can have either 3.73 open axle or 4.10 limited slip.

With stock-size tires and a calibrated speedo, 1,800 to 1,900 RPM at 70 MPH sounds like maybe a 3.55 axle, but Ford hasn't offered that ratio in '99-up PSDs.

His (my buddy's) E-mail is not working, can he sign up under my E-mail and get his confirmation without screwing up my screen name etc...?

[/ QUOTE ]

Probably not. His registration won't take if his e-mail is the same as another member's. But the fix is easy. Get a free e-mail addy from www.hotmail.com or www.yahoo.com or www.msn.com or similar. I've been using HotMail as my primary e-mail addy for several years now with no problems

My Sierra Blanca (Spanish for White Mountain) in the sig pic was a great pickup for 11.5 years. I sold it several years ago. I drove a hand-me-down 2003 F-150 SuperCrew 4.6L 2V for a while, but it was unacceptable for towing more than a rowboat. Replacement is a 2012 F-150 EcoBoost SuperCrew Lariat that tows my 5,000-pound TT like a dream. Replaced the 2012 with a 2019 F-150 3.5L EcoBoost with max tow.
