He changed the compressor.
He changed the compressor.
I have been trying to decide if I am keeping my IDI and turboing it or selling it and I was leaning towards selling it.
The little bit thats done to yours and the numbers its making have changed my mind, The IDI is staying and I'm going to build it up.
What are your EGTs like? How well do you think the engine will take that kind of boost longterm? Most people say you can't go over 15-17 PSI with stock CR.
My opinion on that is that the engine isn't hitting that high boost all that often so I don't think it honestly makes that much difference. But who knows until multiple people try for a prolonged period of time.
NMB2, I wouldnt start basing the moose parts yet, it has been proven time and time again that kens stage 1 injects typically have a TERRIBLE spray pattern. Mel has put a lot of R&D time into both the moose pump and the moose misters. I would be willing to bet that if you installed a moose pump and misters you would see improved HP and MPG over the stuff that Ken typically ships out.
Firstly, I do NOT want this to become a DPS vs Moose bashing debate. Both products are good, and I have no issues with Mel or his products, just a different opinion.
That being said, I will start here.
it has been proven time and time again that Kens injectors are crappy. That is NOT proof, it is opinion. Ken thinks they work better that way, Mel thinks they dont. I personally think that the spray pattern misting makes no difference, and Kens injectors putting more fuel in, faster, is better.
Your bet is wrong... Look at the power curves. That has nearly nothing to do with my turbo. It has 100% to do with my Pump, Ken's timing and fueling curves are better. Also, I get 17-20mpg highway unloaded with a ZF5 and 4.10s. 11-12mpg loaded 65-75mph. I don't think there is much improvement to be made.
You might have gotten a good shipment from Ken, but many users have had problems with his products AND his service. Ken has a lot of experience with IDIs and im sure if he took his time to develop consistent quality, we all would hold him in high regards.
Beating a dead horse, I don't want to debate it anymore and **** anyone off, I just disagree that he ever had poor customer service, maybe hes just a real convincing guy over the phone.
About Heaths Moose pump and misters dyno run, Heath ended up making more boost with the misters would could have potentially lead to more power, but his turbo was so far outside of its map that he was super heating the air and in fact loosing power. If i recall there was a common acceptance that if he had a bigger turbo he probably would have made a lot more power.
I ran 20+psi on my stock ATS turbo. Making about the same exact power I have now, there was not that big of a difference. I didnt have EGT issues, I didnt have superheating issues causing me to lose power or mileage. I looked into the turbo upgrade for use with other plans in the future. They can speculate all they want, but thats all it is, speculation, not proof. 15psi from Heaths turbo is NOT enough superheating to lose power, those are just excuses.
Finally, very nice numbers. Being a poor college student I dont have the money yet to create a nice IDI build. But your work has given me hope and inspiration that my IDI will one day put down decent numbers. Keep up the good work and lets see more dyno runs.
I'd think the engine could handle it for "occasional abuse" but like any engine, you crank it up and you are decreasing the life of the engine. I'm sure if IH could have made these trucks hold 300hp for near their service life they would have come from the factory that way.
That said, I'll all for making these old pieces of Iron get some early 2000 model power levels
Yeah, I am curious as to the longevity of these mods. the numbers are great, but at what cost
You do know the shop I used to work for Precision Tire here in Beaumont Texas has a Dynojet right?
That is a moot point. That's like saying the PSD didnt come from the factory with 300hp because it couldnt handle it. Or the 12v Cummins... 89-93 was 160/400.
I bet to differ......the question was asked about the LONGEVITY of an engine at high boost and power applications like yours (high boost and power being relative to the engine); thus my response...... The comment is very relative.
