I doubt they made a wicked wheel for the GM series of turbos. I would google the wicked wheel guys and check there site

The wicked wheel is nothing more than an early 99 7.3L powerstrokes turbo wheel. Your thinking the batmowheel. I would be awful leary of somebody touting 350HP claims from a 6.5 with a set of head gaskets, studs, tune, and this part. And depending on the quality of the casting you could be making a bomb under your hood. It could be a good product, but I sure wouldn't want to be the beta tester. I still don't see how this will do anything about the restrictive exhaust side of the GMX series.

I'm also leery of 350hp claims. "If it was easy, everyone would be able to do it."

Kinda makes me wish I hadn't ditched the GM-8 with excessive shaft play but like Ferm was cautioning about, who would want to report that thing turned into a bomb and sent all that shrapnel into their motor? Not me, not with this motor anyway, maybe the old one but that boat sank a long time ago. Still it looks interesting and I'd pay a Dollar to watch someone else run it.:hihi:

I saw the 350 number and thought he meant with OTHER mods, IE another turbo but reading it again, he says with that wheel, :mad2:

From a compressor standpoint, if you get more mass at lower boost, then the restrictive turbine doesn't come into play.

250 with lower EGT's, I can buy that, but 350 with a tune and this NO WAY! Heck it is doubtful a stock DS4 can supply the needed fuel to hit that number, let alone with the GMX turbo(even a modified version).

I have two stock gm4s laying in my garage is anyone wants to send me one I would gladly report my findings.:) I would also hate to be bill heath right now. If someone buys this and doesnt get the advertised hp that could be some bad publicity. Does he even know this guy just promised this kind of hp from his tunes.

I emailed him asking about dyno sheets for the 350 hp and said we can't even get HX40's making 350. He sent me two replys. He has no clue, :(

This power quote is for the electronically controlled engines with a computer tuning upgrade from heath Diesel. Not just throwing fuel at it.

An HX40 is not the best choice for this application due to considerably heavier rotating components. I think it would be pretty sluggish spool wise? Bill Heath had me look at a T04 "P trim" turbo someone else made for him and he said he made 440 horsepower on it but it was sluggish as a turd. It was supposed to be a Garrett turbo and it was definitely not, it was a Borg Warner version of the Garrett T04 P trim. I spend a lot of time weighing rotating parts because this is a huge factor when looking at spool rate. The "P Trim" turbine is not a great match for this without going to a considerably smaller A/R than what was being used on Bill's sample turbo. I am a firm believer that if you have an electronically controlled engine package underhood (GM5-GM8) you need to see Bill about his tuning package or you will not see what you want. Careful parts selection, time , and patience are what is needed to get a combination that works properly. Nowadays everyone is a turbo expert, everyone except the turbo specialist himself.

Email him back and ask him how he's getting enough fuel to make 440HP. I know Heath is respected in the 6.5 community, but I call BS on him breaking 350HP let alone 440 HP on a DS4 truck unless he has a completely custom DS4 up his sleeves. In a perfect world the DS4 is supposed to be capable of 120MM3 of fuel according to the math on plunger size, and even that is only enough to get you around 350-375HP in an efficient engine. Take into account pumping losses and injector bypass and you fall a bit short of that perfect world injection amount.

I agree. I was also wandering about the restrictive exhaust side of the gm turbo. Getting more air in is great but you still need to get the air out.

The wicked wheel is a lot more than just early powerstroke wheels. They make them for dodge, GM (not the GM3) and ford applications of select years and turbochargers. I would do some more research Ferm. http://www.dieselsite.com/wickedwheel.aspx I just emailed them about there HX35 wheels to get some more information. So I'm sure he is not thinking BatMoWheel

Yes, it is restrictive and the agreement seems to be around 10-12 psi, so if you upgrade the compressor side, you can run lower boost and produce more mass per psi thus your not generating as much backpressure. For a budget, its a good idea.

It looks like somebody decided to come up with there own batmowheel copy and call it the wicked wheel. The wicked wheel used to be known as an upgrade for the 99.5-03 7.3L powerstroke. It was just a bone stock early 99 turbo wheel which had less fins on it. They called it the wicked wheel. Looks like somebody decided to expand on it and copy the batmowheel and call it a wicked wheel.

The BatMoWheel and Wicked Wheel are TWO COMPLETELY DIFFERENT WHEEL DESIGNS. The wicked wheel was the first generation of wheels, originally intended for Powerstrokes. Since then, the Wicked Wheel 2 has come about, a better design than the initial with various applications of use. Based on two different designs. Not copies.

Ah.... similar principle as the att. More power on less boost because turbo is moving more mass. Makes sense and the price is very affordable.

I relaize they are 2 different designs, but snazzy catch phrases for a product nonetheless. The origanal "wicked wheel" that was sold was an OEM part for the early 99 7.3's. 99.5+ 7.3's had a wheel with more veins on it and was known to surge at higher boost levels. They went to it from the early 99 design to slow the turbo speed down and make the turbo quieter, but this results in turbo surge at higher boost levels from a turbo overspeed condition. So they would swap in the earlier wheel to help with the surge, and it was named the "wicked wheel". I am very familiar with the origanal wicked wheel because way back in 05 when I bought my BURB, I almost bought a 7.3L EXCURSION instead. So I researched ALOT on what the wicked wheel was, and how it was found to be nothing more than an OEM 7.3L turbo wheel for the early 99 marketed as something special.

Yes, we both get that, but you can't say a Wicked Wheel is just a copy of a BatMoWheel. The only thing they have in common may be a "snazzy catch phrase". The original Wicked Wheel was OEM design but has been further built upon for the Wicked Wheel 2 which has been expanded for multiple applications. To say they are a copy of each other seems very ill-informed in design parameters and use. If you would like I can email DieselSite and ask them why they "copied the BatMoWheel" and let you know what they say?

I wasn't implying they were copies of each other, I was trying to say they used a catchy phrase to copy each other. batmowheel wicked wheel, to me they are both catchy phrases. And the origanal wicked wheel wasn't just an OEM design, it was a friggen off the shelf OEM part marked up 250% until they got caught and people started buying them direct from the factory. I remeber all the whoopla over on the FORD boards once it was found out to be just a stock 99 wheel.
