Ism cummins 410 hp with emissions - maddsports - 08-21-2019 I am trying to get this ism cummins to be a fuel efficient truck it currently getting 5.5 mpg and. I would like to get upper 7 plus it had a high crankcase pressure code and a leaking exhaust o am planning to do a egr tuneup to see if the mpg can improve. Also I was to figure out the best sweet spot to govern it so it gets the best mpg ratio is 3.78 or 4.11 so far I think 65 is the best but over 65 mph the rpm is 15.50 of higher RE: Ism cummins 410 hp with emissions - Rawze - 08-21-2019 better mpg starts with slowing down a bit, having a boost and pyro gauge, and driving by them. A healthy engine is also required.

Hopefully, I'll get a chance to meet you face to face when I come down to Mr Haggs friday RE: Ism cummins 410 hp with emissions - Rawze - 08-21-2019 The big link at the top called "Rawz's book" RE: Ism cummins 410 hp with emissions - maddsports - 08-21-2019 I not chasing speed I just bought the truck and that what I discovered with it so I am trying to make the truck run as efficient as possible it a pretty light truck with great suspension I just haven't found much info on ism engines RE: Ism cummins 410 hp with emissions - maddsports - 08-23-2019 Any experts on the ism cummins engine I am trying to get it working just right RE: Ism cummins 410 hp with emissions - maddsports - 09-08-2019 So I have the 9200i in the shop at international the verdict with the exhaust leak was a bad manifold section at the back of the motor. I also ask them to pressure test the radiator and cac and found out the cac is leaking pretty bad so now I know where my bad mpg is coming from. I did a egr tuneup and found the egr to be very clean. It had no soot in the egr delta p tubes or cross over tubes or egr pipe that was very surprising. They want 1378 for a new cac for that truck but I am looking for a cheaper alternative. I am thinking about getting the old cac recore.

I am thinking about getting the old cac recore. be very careful of aftermarket CAC units. They are quite often more restrictive and cost you fuel efficient problems far worse than the few moneys you tried to save. This is especially true of $Uuralite and a few others that are heavily advertised. |
