Add a decent turbo pump and injectors to a stock NA IDI and it will walk any stock OBS powerstroke any day of the week.

Add a good turbo, intercooler, pump, and injectors and it will walk most modified 7.3s and stock 6.0s if not 6.6's and 6.7's

Btw, you can a pump for the idi that has shown 350whp and all 8 matched injectors cheaper than you can a HPOP
soory but there no way a na idi can beat a stock psd in a race maybe off the line but after the turbo spool the psd will be gone

Between a stock turbo IDI and a stock gen I psd? Power is the same. I know a guy who has both and prefers towing with the IDI but says the psd is slightly faster empty. FWIW his idi gets 19 empty and the psd about 17

You keep telling yourself that a 250-300hp IDI will out do 350-600hp engine

That is OBSURD

Between my neighbors 95 stock psd, my 93 stock idiT, neighbors turned up 86 idiT and my turned up 91 idiT...the 86 and 91 will do circles around the PSD. The stock 93 might take the stock 95psd off the line but PSD would beat it up higher. I think the valve cover said its rated at 205 or 215hp at the flywheel, when the 93 says its rated for 190 at flywheel.

Get a turbo IDI

yeah,your pushing things there Hairy lol.
we have all kinds of dyno's showing tweaked moose pumps,intercooled trucks showing just over 200 hp out back with crazy over spooling of the stock turbo's outside what they're made for.
these engines take a lot more work like what nmb2 has done to start comparing them to latter psd engines of course.

a turbo idi with proper tune,is very comparable in my experience to the 94-97 7.3l in stock form too.but remember those trucks have crushed down dp's too.just a real turbo dp,and the stroke has her all back id guess lol.they're not real far off,but a long,long ways from a mild build 7.3l and just not comparable to anything after the 94-97 psd.

the old truck part is more concern,time consuming,money involved issue over any concern of my idi.the engine just goes.the truck is what keeps needing attention.

the trans is your problem. for the trans you are doing pretty good. swap in a ZF5 and you could probly hit 17-20mpg.

Really? I would think that he would be doing better than 13mpg. Bet there is something else going on. IP/Injectors? maybe timing?.

Biased much? Drop $2500 into an IDI and the same in a psd and lets see who wins. Stock HPOP is good to what.. 300hp??

More along the lines of 300-400 vs 300-600, and most 7.3psds are NOT anywhere close to 500

And racins engine is what.. chopped liver? lol

You guys crack me up. All the more motivation i guess. i love proving people wrong.

On top of all that, a Moose pump is nothing special, an over-priced rebuild. NMB2s engine was a 6.9 with cryod rods, shaved pistons, a good pump and custom turbo. Nothing spectacular, he was just the first one to do it. Where as racins engine is a bone stock 7.3 IDIT with 160k+ on the ticker with nothing but studs and headgaskets with a pump and turbo and he made a whole 15whp less than NMB2's?? and racins wasnt even tuned and had a slipping clutch.

Nmb2 over built that engine. That's where that price tag came from. Racin has much less then 6k in his. Honestly at this point it's basically who can get more fuel and air...2k spent on idi fuel and air mods, compared to 2k in psd fuel and air mods

what is your basis on the $2500 number? IIRC NMB2 has about $6K in his engine. that was doing as much as he could on his own or getting really good deals on things. your also talking about a "pimped" out idi engine keeping up with a stock, newer psd. throw a tuner on that and that new truck will wax the IDI all day, every day, doing anything thing.

let's try this, spend $6,000 on an 7.3L PSD. where do you get with that? we know where abouts you can get with that on an IDI.
Ok let me be more specific. a 150cc pumped IDI should be in the neighborhood of 350-400hp tuned up and an efficient setup. That is more than enough to keep up with or walk on a STOCK new diesel, ie: 6.7psd or similar which are 400bhp which is +/- 325whp which is also about the norm for a chipped/exhaust 6.0 and a 7.3psd with injectors turbo, exhaust, tuner, etc etc.

NMB2 overbuilt his engine, period. nothing wrong with that.

A new diesel doesnt even need a tuner to outclass an IDI, so yes not much comparison.. yet. But a tuned/ pumped IDI will still hang with it. (im basing this all off of numbers of course)

I wouldnt spend 6k on a psd, nor do i know where that would get you, i would estimate somewhere around 500whp. As far as throwing out numbers you cant base your basis off of one persons over built engine.

I know if i spent six grand on an IDI i would be looking at a number around 550whp or better. But i dont know if i will spend 6k on an IDI.

My basis on the 2500 is that is what it would cost me to build a 350+whp IDI, bare necessities, but still. Im no psd expert but afaik youre looking at well above that to eclipse 300whp. If im wrong im sure someone will be more than happy to "enlighten" me.

My POINT is. The 7.3IDI is every bit the 7.3PSD's equal in my own opinion. I was simply tossing out some numbers for rough comparison and it got turned into a pissing contest.
