Our Review: Stock Turbo BATMOWHEEL!
Our Review: Stock Turbo BATMOWHEEL!
Batmowheel Review – By: Matthew Cresto of FJ Performance in Export, Pennsylvania.
We were asked by Bullseye Power and ASP Turbo to test the new Stock Turbo Batmowheel for the Dodge SRT-4. Here's some information about the part, and what we found out in our results.
Test Vehicle: 2005 Dodge Neon SRT-4 ACR edition.
The Mods: Upon delivery of the test vehicle to us and inspection of the vehicle, it's initial mods consisted of just a K&N intake system and the Mopar/Borla exhaust system with Mopar 2.5” Test pipe (catalytic converter delete) for power mods and Megan Racing coilovers and Energy Suspension control arm bushings for suspension mods. We installed the supplied Godspeed Big Front Mount Intercooler, nameless cold-side hard pipe with Greddy Type RS-II Blowoff valve, Mopar Stage 2 wastegate actuator, Mopar Stage 2 injectors, nameless Ported exhaust manifold w/ elbow mod, Ported stock throttle body, OBX 3” Dual exhaust, OBX 3” O2 housing, Autometer Digital Wideband Air/Fuel Ratio gauge and Digital Oil Pressure gauge.
Initial tests showed the vehicle to make 228hp and 251tq before mods with the stock ECU calibration. During tuning with the 2.5” exhaust, the vehicle refused to go over 250hp, which is when the customer opted for the 3” exhaust parts and the ported exhaust manifold. After the mods and tuning, the vehicle made 279hp and 355tq, while holding over 300tq from 2800rpm up to 4800rpm, slowly tapering down to 221tq by 6000rpm.
This gives us a good base for testing of the new stock turbo batmowheel. Installation was pretty straight forward and only took a couple hours, with the hardest part being the snap ring that holds the center section onto the compressor housing.
Now comes the fun part...
Initial dyno pull after installation yielded an instant 11hp gain with NO change in the tune. After a few tweaks of the tune, the final numbers ended up being 317hp and 425tq for a total gain of 38hp for a 13.6% gain over the stock wheel! There's one small problem though. WE RAN OUT OF INJECTOR. With the Stage 2 injectors and the stock returnless fuel system, the car was leaning out from lack of fuel.
Results and Our Thoughts:
This new compressor wheel has great potential, but for a bone stock car would have minimal gains. Obviously the more supporting mods you have, the greater your gains will be. For cars with similar mods it would be a great additional and well worth the price for the power increase. This turbo holds more power to redline and doesn't fall off nearly as hard as stock. As always, proper fueling is important and can make or break your power potential.
After reviewing this part, I would definitely recommend this part for anybody looking to break the 300 mark without extensive mods, and I myself will be further testing this unit on my own car in the near future to see what a maxed out mod car can do with it.
If anybody would like to further the testing of this part and has similar or greater mods than our test vehicle, we welcome you to bring the car down and we will see how much your car can make!
Thank you,
Matt Cresto

Stage 2 injectors with a return line w/ rising rate regulator would be sufficient, otherwise at least 750cc injectors

Here's some commonly asked questions that I apparently didn't mention in the write-up. I'll be updating this as they come in...
Q. With this wheel, do we have to have the housing machined to fit?
A. No. This unit is a direct replacement for the stock wheel.
Q. How long does it take to install?
A. About 2 hours. We provide detailed instructions for installation to make your job easier if you want to install the wheel yourself.
Q. Don't I have to have the turbo rebalanced?
A. Getting the unit balanced is never a bad thing, but, the stock SRT turbo is component balanced from the factory, not assembly balanced. This means that as long as the part you put back on the turbo is properly balanced, the unit together will still be balanced within factory spec. The Batmowheel comes balanced from Bullseye Power, so there's no rebalance necessary.
Q. Does this include a whole center section?
A. No, this is just the wheel itself. We don't rebuild turbochargers. If you feel your turbocharger needs to be rebuilt first, we will be happy to help you find a suitable company to have your turbocharger freshened up.
Q. What fuel was used?
A. All testing was performed, from start to finish, on Sunoco 93 octane pump gas.
Q. You said it ran out of fuel, why?
A. The factory fuel system is a returnless fuel system, so when you go into boost, the air pressure fights the fuel pressure, effectively lowering your fuel pressure. Using a return style fuel system with a rising rate fuel pressure regulator will help prevent this from happening as it will restore the effective fuel pressure by increasing fuel pressure to match boost pressure. This makes your injectors flow the same amount of fuel regardless of boost pressure.
Q. What would my car do with this wheel and xxx mods?
A. I can't say exactly how much your car will make with specific mods. Use the mod list in the write-up for a general guideline of what you might be able to expect from the unit. Other things will impact your potential gains as well, and as always, more or better mods will yield more gains.
