What can a Wicked Wheel 2 do for your truck?


Got my truck back today from the shop, went in for leaking o-rings and had them install the wheel also, o-rings are still leaking though so its back in the shop...But I got to drive it about 30 miles down to the boarder.

What a difference! The truck is a 1995 F250, 285k, down pipe, BHAF and thats it. The original wheel had quite a bit of wear but got the job done. (just made a 2000mi trip towing a trailer) In the short trip that I made, this is what I observed.

Spool - From a dead stop to the floor the turbo lights almost instantly. I would say it spools in half of the time compared to the original wheel. Driving in traffic it is a completely different truck. Downshifting out of O/D into 3rd there is no lag at all. With the passenger window down listening to the exhaust, from 1000-1300rpm the turbo gets singing alot faster over stock.

Power - Even though the truck has stock fuel there is a noticeable difference. Mountain passes in O/D around 1250rpm or so it will pull. To the floor 2500rpm it used to kind of fall off the map, now it will pull until the next gear. More power through all RPM.

Sound - My truck is a true beater. There are holes in the floor, gaps in the doors, no carpet or trim, it is rough and has alot of wind noise. Been like that for a while so I can notice a change in turbo noise. To me it is a hair quieter when its spooling, and a little bit louder when you let off the pedal. I think this is because the Wicked Wheel 1 would slice through the air causing more sound than performance. The WWII moves the air instead of slicing through it.

My truck has never ran better. It turned my old beater into a spring chicken.
Have thought about a tuner in the past but worried about my transmission since it is just a tow rig. Ill take this wheel over a tow tune any day.

I extremely recommend this product!!


10/10 cant wait to put more miles on it and buy one for my Super Duty!

I drove it on Friday on my stock setting (not my 80econo setting) and laid into it pretty hard.  Could only pull about 18lbs of boost.  That isn’t too surprising for my truck on winter fuel and stock setting.  After installation of the turbo I did a little playing around which may not have been too smart but I put it on the 80 econo setting and drove.  I drove it for 15 miles and laid into it pretty good….not to the floor though.  Well, I pooped my pants.  I think it downshifted….went like hell….and rapidly climbed past 25lbs then POP!  I blew off a CAC boot.  I know that thing was going to sail right on by 25 if it weren’t for the boot popping off.  Like I said, I don’t have access to a dyno but it sure feels stronger.  It sounds a lot different.  I won’t know if it totally cures surge until I get the camper hooked up in the spring.  I will know full benefits of the ww2 then.  I don’t use my truck as a daily driver, but I will get it good and warm sometime soon, but it in the 80hp mode and put my foot to the wood just to see what boost numbers I am looking at now.  I will then let you know what improvements I see.  Remember I did the EBV delete at the same time so not sure if all my info will be perfect.  But it does run a consistent 100 degrees cooler on the EGT’s.  ~Todd W.


The results before were 14 lbs of boost at 1200-1250 EGT's and that was all she had. Achieving 10 lbs of boost was a challenge for the truck, partially from a chewed up wheel but none the less, it was working hard to produce 10 lbs even in the cool climate here in Alaska. Last night on the way home I waited patiently for the traffic to open up just enough to give me room to smash the throttle and see what, if any results the wheel made. For a lack of better term, the results were AMAZING!! At roughly 3/4 throttle (because I was in traffic), 38 degrees, and just about three car lengths I saw 22 lbs of boost and EGT's never got over 900. This isn't where it stops, my cruising speed of 60-65 produced at most 1 lb of boost, I now cruise at nearly 5 lbs. The boost lag... it's non-existent. This thing (with straight pipe and wheel) reminds me of a 6.0 sound. It spools up immediately off idle and doesn't slow down until I let off the throttle. My EGT's at cruising speed ranged in the 850-900* range, I see no more than 700* when running the roads at 60-65.  ~ Nicholas S.


I installed the wheel today. OMG what a difference.   At first I thought, OK yeah I hear the difference. And figured well you always do stuff to your vehicle and psychologically think oh man what a difference. So I said nope not gonna do it, not gonna buy into the hype it’s gonna have to prove itself.  Holy shit did it ever.  Night and day from my stock one.   ~Tim J.


I just purchased my WW2 and installed in my 97 OBS this weekend. I just have to say totally awesome. I have a consistent 5 to 8 pounds of boost more then I ever did. The truck is so much more responsive it feels like a totally different truck. I think you hit a home run. Thanks.

Got mine installed, f***ing amazing, sounds sweet, surge is gone, and the extra power is great...

Hey Bob. I got the wastegate adjusted on it and holy crap! There's no turbo lag and no surge what so ever. It hit 30 pounds of boost like it was just a walk in the park! I have only been able to get it up to 34 PSI so far (haven't been able to keep my tires stuck to the pavement long enough to see if it will push anymore than that). All in all I am extremely happy with the wheel and your customer service. You weren't even the one that sold me the turbo and you were more than willing to walk me through it to diagnose the problem. Again I can't explain how pleased I am and will definitely be shopping with you again.   ~Drew L.


WW2= Amazing!  Definitely an upgrade from stock wheel. The truck spools so much faster and I got an extra 5 lbs of boost out of it. I get 37lbs total now. Very loud turbo spool and an amazing deep low end tone. I’m very very happy with it for only having it in for a couple hours. I will put a lot of time on it tomorrow cruising around town. Thanks a lot guys. Outstanding job~ Robby C.
