high egt #s at 1500rpm
why should it be so high..a leak or fuel probs....
|
how high is high?
pre-turbo or post-turbo on the EGT probe? is it just cruising on flat land or climbing a hill? is this in stock mode or with the adrenaline turned up? stock exhaust or aftermarket? stock turbo? |
my bad....... its a buddy truck... he has a blue chip and a smarty.... stock. turbo. 5 inch exhaust........ pulls 900 flat land....... could that be an exhaust manifold air leak. or fuel prob.....
|
i'd look at boost first. what PSI is he running? i'd make a pressure checker that can be found here---> https://www.dieselbombers.com/cummin...tructions.html and then i'd look into prolly upgrading that turbo. IIRC some of the HY's had a 9cm housing. that can cause some seriously high EGT's.
i highly doubt it is an under fueling problem cause if it was the egt's would be reading cool. overfueling maybe. |
thank you.. ill tell him to look in to it.
|
if it's an hy it's a 9cm housing and that will cause high egts. what year and what trans?
|
Yea...what truck? Too much fuel and not enough air seems like to me! Might want to look into upgrading that snail soon!
|
auto or manual lugging it in a high gear will bring the temps up. drop the power level. drop a gear. or get twins. my truck hates anything below 1700-1800 rpms anyways!
also have to look at tire size and gears. 3.55`s or 3.73`s and 35" tires will not help this either. |
It's my truck. Curtis and I were talking about my temp and who better to ask than( everyone ).
3.55 gears 33" tires Probe post turbo ( add 250 ) At the time of the egt's 595 , 3lbs of boost , flat ground , 1511rpm's 5th gear - NV4500 60mph Defuel set at 900 degrees Prob. not enough air?? :humm: |
How does it do around 1800 rpm?? Sounds like you need to grab a lower gear and get those rpm's up.
