on the high way at like 70 with the pyro after the turbo its like 700 F and 15 psi boost. that was with cruise control on. What is a normal temp post turbo on the free way? all i have is a 12 plate slid and some pensicola stage two injectors. would the wrong spray pattern take the egt up alot more than normal? i know i need my timing set bad would that be part to?

 

seems a bit high that means its running around 900 * pre turbo i run at like 70-75 with cruise on and i run at about 5-600 post turbo with a #6 plate slid forward... but i dont have injectors so dunno seems a bit high to me

 

yh thats wat i thought. idk the only thing i can think of is the timing. i thought u had to add like 400 degrees post turbo?

 

The post turbo readings can be off by 400 degrees, maybe more maybe less... I know when I had my bully dog gauges they said post turbo was off by 150-250 but the mechanic who has been helping me and teaching me, said that those numbers could be off by a couple hundred degrees

 

so does any one no if timing would cause it if it slipped down to like 6 or some thin crazy?

 

ive never herd of timing being an issue with high egts, does it smoke white at idle or past 2400RPM, get you pyro done pre-turbo when that tap comes in

 

i still dont understand how in like 6inches the temp would cool down by like 300 400 degrees. im goin to ask glowshift if i coud get one of those fittings

 

I hate to be blunt - but you get what you pay for.

As well, your thermocouple should be preturbo.

 

ill help ya get it figured out but, ill call around for that fitting for ya cant be more then a few bucks

 

Its not to hard to believe actually. Its pretty much simple math if you think about. In the space it has to go before hitting the probe, the exhaust has been intrain with air and can cool down quite rapidly.
Say you pour a cup of coffee at 200 degrees, but the time you actually pour the cup, put the pot back, and take a drink, the coffee has already cooled down 30-40 degrees. But the longer it sits it starts to cool down more slowly. So basically, at first the temperature drops rapidly but as it sits it goes down more slowly. Its pretty much all based around the algebraic concept of half life, if that makes any sense...
