Got gauges installed today....what are the safe zones for them?? - Diesel Forum

hey everyone,

I had some autometer gauges put on today for boost, tranny temp, and pyrometer. Can you guys tell me what the safe operating temps are for the tranny and the pyro?

Also when driving down the road at say 60mph at a steady speed the boost gauge only shows about 1 lb of boost but when I really get on it I can only get it up to around 6 lbs of boost(without a load on level ground). I was wondering if this is normal? The truck is a 1997 f250 extended cab with a tymar intake and tymar downpipe/exhaust but other than that it is stock.

Any help/advice is greatly appreciated. thanks.

If your pyro is in the manifold not above 1250* if its in the dp Id say 1000* but Im conservative on egts. On boost I think its 20lbs on tranny Id say 200* or less, your boost at 60mph sounds right, I would think getting into it you should see higher than 6lbs but I didnt have gauges until a chip so I dont know what a stock truck would do on boost.

thanks big dan. I'll have to double check where they tied in the pyro. It was around 98 degrees here today and the tranny got up to 180 degrees without a load. Considering the temperatures outside I guess that was ok. Thanks again!

You should probably be seeing in the low teens for your boost pressure on a stock truck.

yea 15 pounds at full load on a sticker without a chip.

Just to let you know what im running...Granite, i have downpipe and tymar intake, so take it for what it worth, Running 70mph I get 5psi boost and egts are 800 with tranny at about 165.. on level ground with cruise control(no load). If i get on it going up hills ive gotten boost upto 23psi and egt 1100, tranny 180. Just wanted to give you a reference, hope it helps.
