Oh I gotcha

 

Dude.. you dont get it. I liked you better when all you did was cry because your turbo doesnt whistle.

Want me to paint a picture? NMB2 and racins engines make more power than all current and prior stock diesel engines, and some even modified, (some more / less than others).
Its pretty obvious that the newer platforms can be pushed farther than the IDI, thats holds true for pretty much every platform, IDI<7.3<6.0<6.4<6.7 im simply making the point that IDI's are alot more competative with these newer platforms than people have or do give them credit for.
If that doesnt get the point across, idk what will. I am done helping you derail this thread that much i do know.

 

C'mon guys, calm down, lol...

Lets look at it like this.... The fact that the debate is even this far is something to be said... I am confident that the IDI can match the output of the PSD CC for CC... At least til we are tapped out fuel wise... Right now we are limited to 180cc's (Short of going Brandons route), and the 7.3 PSD has access to more fuel, so its going to make more power, thats just the way things are until somebody can find a way to get more fuel from a DB series pump... What I find fascinating, is that fact that we make right power right on par with a PSD, CC for CC, even though we are IDI... Ever heard of the IDI making 15% less than DI? Well that doesnt apply for us... Might have to do with our heads being better.... Either way... Dont ever get into comparing an IDI to a PSD, just out do them where it counts... The 7.3 and 6.0 are easy to do that to, and only the most worked setups are going to out do the most worked IDI setups... But NMB2 and I both out dyno'd a 6.0 KR with intake, exhaust and chip... That should say something... Common rail is a whole other ballpark, and I dont see us competing on any level with those guys, but as far as the 7.3 and 6.0 goes... We can make more power cc for cc, for less...

That being said... Things are only going to go as far as they are pushed... That is going to be the biggest determinant of all...

 

6k into a idi and you have what? 400RWHP
6k into a 7.3 and you will have about 500 RWHP
6k into a 6.0 and you will have over 600RWHP
6k into a 6.4 and you would probably have 800RWHP

 

No, not entirely...

If you want to look at the same scale of supporting mods, you could do a 400whp IDI for 3k... You would be hard pressed to get 400whp from either a 7.3 or 6.0 for 3k... 6.4 is common rail, like I said, not even the same class... Obviously more dollars are going to benefit the 6.0/7.3, its the nature of the beast, but if you look at CC for CC, you could make as much power, cheaper, with an IDI...

 

Everyone and they mother has a 7.3 6.0 ect that has 400 hp but not everyone has a idi with 400 I would stick with the idi cheap easy to work

 

To the OP. It sounds like the PSD is a good deal, so if you want it get it and have 2 trucks. If ou are purely looking at the functionality of the truck for your job, either will do the work. I would stay with the IDI. It seems to be a simpler system to work on/repair plus it is already paid for. You could always sell the 2 cars that you would be trading and use the funds to modify the IDI. Just my 2 cents.

Folks, listen to Racin'! He's 'bout the only one posting here that isn't just barfing up numbers he read on the Internet. And his point (which is backed up with pics vids and dyno numbers) is that the IDI platform = PSD platform if you level the playing field and equip the IDI with what PSD's get from the factory (turbo, intercooler, and better feuling). In all fairness, if you are talking about the cost of building up an IDI vs. PSD you should start with a long block of each and see how much hp can be had for the $$ spent. You just have further to go when starting with a bare, NA IDI, and you are limited by the fueling ceiling of the DB4. IDI is definitely cheaper power, and can be pushed to a level where you begin breaking driveline components. Beyond that the cost of the hp is moot anyway unless you are budgeting for building the rest of the vehicle to handle crazy hp.

 

Some real world number for those doubting the 7.3PSD
real world PROVEN numbers good for 500RWHP time and time again. Not a one off

CHip......................400
Intake..DIY6637.........50
Exhaust...Flow-pro....320
Injectors..238/100....1650..Rosewood diesel
Turbo....S366..........2000
HPOP.T500..............500
E-fuel. DIY............. 500
Push rodsSmith bros..200
valve springs..910-16..85
---------------------
5200

Plus $500? misc

And the best part is....
EVERYTHING is a bolt on, no custom ANYTHING which keeps COST down

 

Thank you for the breakdown Brad!

 

THIS! ...I like how they keep saying 6k is what it takes
