Took some Temps of the new motor....

[88stangmangt]

After a mile or two easy put put run i took the following temp reading to see where i stand.

#4)169
#3)240
#2)130
#1)100
Dp)360
turbo exhaust side)350-400
These readings are off the primary's off my Stinger Centermount header at the base of the header All reading in Ferenheight. They do vary as well and i only took them once....what do you guys think.?????

i'm concerned that cyl 3 is so high. hmph.... i gotta think on this one. they should be close to each other as far as temp wise

took some more temps

4)275
3)340
2)250
1)190
they are pretty close but another thing that hit me is the #1 cyl is the first to get hit with the cool water....so every cyl should get a little warmer so it should vary on the exhaust temps correct???

thats true but why the drop from cyl 3-4 cause 85-100 degree difference from one cyl then all four just seems IMO. how much boost are you running? next question how hard where you driving before you took the temps from the frist set to the second? i take it compression and all that are good and cyl leak down is good? i'd take the hour to check those. emphize on cyl 3. it runs like a top?




i was just thinking whats your timming at? it could just be the timming and the cam your using.

Wouldn't the cylinder temps be high across the board if it was timing? Is it possible that #3 is a hair leaner than the rest? Maybe a partially clogged injector or the really, really odd chance of a slight intake gasket leak right at the number 3 port? entry.

What do the plugs look like? Do they look all look the same?

thats what i was thinking but since they are so far apart that was making me think...
