IDI Wicked Wheel 2 - performance test

Just added a WW2 to my '93 F-250 with (currently) a Factory Turbo 7.3 IDI.
After this test, I did some romping on it and now it boosts a couple PSI more - it may have just needed to tighten everything up a bit. Haven't taken it out for a long drive yet, though.
Edit 1/21/2019: She's still doing fine. Turbo sings, still not as good as a Banks, but better than pre-WW2. Still have a motor with a lifter tick, which may well be hurting flow, but as long as it keeps starting up nicely in the morning and doing everything I need it to, I'm not ready to fix/modify it.

If you have the wastegate tube disconnected like that you’re just releasing boost pressure. You have to keep it hooked up. just crimp the hose.

[@groundtogreen1140]

Did you wire the waste gate lever so it actually stays shut? Just unhooking will still open it. You should be hitting 25 easy with a friggin 110 lots of guys on a stock idit pump have hit over 20.

[@groundtogreen1140]

Might also have a massive boost leak check and see if the up pipes are sealed well

[@ryanpaetz3643]

@@groundtogreen1140 do you think it's safe if your not studded? I dont wanna get a stage 1 turbo from R&D but I do want a little more power and boost...and if i did get it should i install how he did it or take the turbo out to do it?

[@That-Guy.]

Ryan Paetz Stock idit shouldn’t push anymore than 14-15. Chances of blowing a head gasket are very likely. Get after market headstuds along with the turbo. APR headstuds on the R&D site will work great. I disconnected my wastegate and I push about 11-13psi

[@FreeStatePatriotTt]

Propane injection and 3” down pipe. Lots of more power.

[@mattsmith8110]

Would you say the wicked wheel was worth it?

[@MacRobbSimpson]

Hm, forgot about this. Yes, I'd say it was. It's not a massive gain, but it's a cheap improvement.

[@mitster85]

its not boosting more than 12psi because its got an internal wastegate ( they all leak when pushed too much), external ftw!

[@Paydaymaro]

Are you running head studs with that pump and injectors?

[@MacRobbSimpson]

No, I am not. I have head studs in a different rig, the high-HP one with a bigger than stock turbo, but the head gaskets will hold fine with bolts and a reasonable 200-250RWHP. The one thing that will kill them, though, is overheating the motor, especially after many years.

[@maxdavis8995]

Hello just wanted to throw it out there I had the same issue for awhile more boost is no help unless you want a money pit. But if you can part shop and or have a buddie that knows what's up to help set up a intercooler on it that's the route I went. More boost is nice but a damn good intercooler is were it is. Denser air with the boost. Denser air makes more power.

[@maxdavis8995]

With less smoke more efficient and better feul. Added with a nice pump that alone can get better results then just throwing more boost at it

[@MacRobbSimpson]

After seeing the video Gale Banks has put out recently, I am inclined to agree with you. Dropping the temperature makes a *huge* difference. And on the other rig with the turbo making 27 PSI of boost... well, with a good intercooler, I should be able to double the available air easily enough... More fuel and more power! I'm kind of thinking that this setup(factory turbo, probably with ww2) plus a decent intercooler might well be good for 300rwhp, when pared with a 'moderate upgraded' IP like the RD2-110. Get a 150 or 180 for my high-power truck and put the 110 on my DD again.

[@michaelkamps5579]

I would look at classic diesel designed there pump fixed all the problems that the db2 rotary pumps have

[@tannerhand18]

What’s your favorite exhaust set up sounds different then mine I have factory down pipe to a 4 inch straight pipe

[@MacRobbSimpson]

My favorite one(so far) is the cheapest - I just took the stock pipes and cut the muffler out. All the bends and curves in the pipe /signifigantly/ reduce noise at most speeds and load levels - at idle, you can't really tell. I do get that popping/crackle on decel at 2200-2800 RPM or so, something the flow-through muffler on my '88 got rid of. One of these days I may upgrade; I can see using 3" or 4" pipe, and a non-crushed downpipe... but for a stock IP, it's not needed at all.

[@wreckerjonny6144]

Load and proud. Straight pipe all the way . Turbos make great mufflers

[@chaycefairbanks4788]

What’s your egts at when pulling?

[@anthonycook3439]

Oh Good ol Sandpoint. I'm not sure why you where having boost problems before the wheel. I get 9-10 psi with a stock pump and stage 1 injectors.

[@skn9895]

Good information, but for the love of God, please try and hold the camera still! I was getting nauseous watching this...

[@2ndspingarage]

You have to have leaks and I'm not sure why you disconnected the battery for mechanical parts.

[@MacRobbSimpson]

Leaks - no, as far as I can tell, I don't; there is no soot buildup around various areas, which even a small leak would produce. And no smoke on startup from places other than the tailpipe. I'm still not quite sure the issue, but one cylinder is /not/ right. The motor still "taps" a bit, same as it did a few years back; not worse or better. When I eventually tear it down, I will probably find something horrible lol. (I'm thinking valvetrain or camshaft). As for disconnecting the battery, I likely did it because of the position of the glow plug controller, which is right there on the passenger side valve cover on a factory turbo model. This makes it very easy to short with a tool, and I get annoyed with the sparks.

[@alienaesthetics347]

Do all idis have that crackle at the end when floored ?

[@MacRobbSimpson]

Depends on whether you have a muffler. No muffler = crackle on decel. Any muffler, even a straight-through glasspack? Really gets rid of it. The first time I heard it on a different truck after not having the muffler was very surprising; I thought something was wrong. I realized it's just some sort of harmonic in the exhaust, and it only happens at a certain RPM range(mainly around 2000-2600 or so)

[@thatbluebricknose]

I’ve got a little straight thru Flowmaster on mine and it still cackles. It’s a 90 NA

[@ami2evil]

No, get rid of the stock Y pipe, do true duals or an H pipe, it's from the restrictive stock exhaust...

[@That-Guy.]

Just did this and the nut came loose. It’s supposed to be a reverse thread and it’s not. How do I get mine to stay on with hand tools?

[@MacRobbSimpson]

Not sure, probably need to get to the back side of the shaft(like you are supposed to do). Impacts are useful for this, though, and let me get away with what I did.

[@chriserdos]

Tie your Watergate shut with tie wire. I make 15 to 20psi all day with my factory garret

[@tannerhand18]

chriserdos same

[@wreckerjonny6144]

Which direction is closed? Mine seems to be stuck where it is ? I only make about 5-7 psi

[@ashtonallen9193]

What does unhooking the waist gate do?

[@Jv19979]

What happen to your other truck that had tbe big turbo

[@MacRobbSimpson]

The #3 rod snapped clean in half about 18 months ago - after the last video was posted. It failed right on cold start. Both bearings were perfect and still moved freely, even 18 months later when I took the motor apart. I've got a new block for it, and going to pick up heads from Typ4/Russ Repair in Newberg, OR, along with a Torque Cam. If I can swing it, I'd like to get it together and running before September 8th and take it to Hunting 4 Horsepower and make some power!

[@aarontheidinut8926]

@MacRobb Simpson darn you. I for some reason thought h4h was Sept 22

[@MacRobbSimpson]

Well, it's good that you know the correct date now!

[@psd28]

rev a cold diesel like that you'll kill it

[@MacRobbSimpson]

Haven't killed it yet! (I'm still amazed by this honestly... it still ticks just like in the video, I use it to haul way too much, and I've put quite a few miles on it these past 3.5 years)

[@psd28]

@@MacRobbSimpson idk what the fuck possessed me a year ago but i know better now lol i got an n/a 6.9 idi now too, when i originally posted i had a 7.3 powerstroke (wonder why i was so fucking stupid huh)

@@MacRobbSimpson oh also i run that idi on waste oil as fuel lol

[@Redneckkid-hl3ty]

I have an r&d stage one kit stage one injectors and stage one cam Paired with a borg&Warner s360 turbo I'm still on stock fuel and can hit 20 psi of boost empty lol Of corse it's a different set up than the factory turbo

[@MacRobbSimpson]

I sure hope you've got headstuds in there. And then, get a proper pump - probably a RD4-150 to match that boost. Otherwise, it's all just wasted boost that isn't helping make power.

[@Redneckkid-hl3ty]

@@MacRobbSimpson Yeah I need to get a bigger pump It is studded and also on stock compression Justin at r&d said to not go any bigger than the 90 cc pump I will be adding an intercooler And it's also 6.9 with 4 speed I average 17-18 mpg with 3.55 gears

[@MacRobbSimpson]

@@Redneckkid-hl3ty Being a 6.9, yeah. That kind of sucks. The sad part is honestly, the 6.9 is mostly a 'better' motor than a 7.3 - more cylinder wall meat, and they seem to run smoother for some reason. But, those 7/16 studs are the limiter, dangit! Hopefully within a year or so I'm going to mod a 6.9 block and upsize to 1/2" if not 9/16" bolts, to see if I can do it. I just need to find the time...
