Which Compressor Wheel Performs Best?

6x6, 7x7, 11 blade, thin hubs, thick hubs, the list goes on forever. We are searching for which layout of your turbocharger's compressor wheel performs best! What is the best compressor wheel for your application? The results are surprisingly dependent on certain factors.
In this video, Charlie explains the differences between cast vs billet wheels, dual plane vs single plane, and flank milled vs point milled machining. Is there a difference between all of these compressor wheels? Let's find out!

Solid overview! Just for viewer reference, dual plane wheels are also often called splitter wheels and instead of being listed as 6x6 or 7x7 it will often be 6+6 or 7+7. Also note that different wheels which can fit the same turbo may have different blade heights, how far the blades go up the center shaft or nose. Another area which can vary is nose and hub thickness, altering the weight and total flow area.

Great explanation Charlie.

[@KCTURBOS]

Thank you!

[@roberthoffman9426]

Thank you, short and concise, very well done with no bias.

[@PowerHungryPerformance]

Excellent explanation guys!

[@Quebecer_Powerstroke]

Sir, what are the benefits and drawbacks of single & dual plane wheels ?

[@KCTURBOS]

The differences are essentially negligible. one isn't really better than the other. Depending on the turbine its attached to, one might spool up slightly quicker on the DYNO. But there are also a number of other variable that play into that equation.

No help at all 😢 you people play your cards close to the vest

good video

Can I dyno my excursion at your shop?

[@KCTURBOS]

Im sure we can work something out! Give us a call 480-688-7160

[@aydenflores4075]

Which ones sound better , have a better whistle?

[@aydenflores4075]

And should I get a turbine wheel paired with compressor wheel to get the best sound or is it not needed? Lly duramax

[@KCTURBOS]

Thats a great question! The compressor wheels dont produce a whole lot of sound, especially in comparison to a VGT turbine wheel. The sound that come from the comp wheel, has more to do with your intake and cabin insulation.

[@KCTURBOS]

The key with paring a compressor wheel and turbine wheel is having the inducer of both sized evenly. EX: a 68mm comp wheel with a 58mm turbine wheel, is going to spool like cold honey. Best way to get that super loud sound is to buy a balanced assembly DIY kit that has a 10 blade turbine and a well matched compressor wheel (we have those on our website) or buy an entire drop in turbo and call it a day. (we have kc Vortex drop on duramax turbos that scream well) Give our customer service a call if you have any more questions, wed be happy to help out! 480-688-7160

@@KCTURBOS I see, what do you recommend for a stock lly vgt turbo to make it sound better ?

[@Kodi5204]

@@KCTURBOSsee I feel like the compressor wheel changes the sound a lot and the compressor bark sound I had so many different wheels on my 7.3 I had 5x5 wheel that had much louder whistle than the stock 9 blade then I got a 7x7 compressor wheel from rd2fs that wheel had a much different spooling sound than before then after that I got a 66/88 6x6 billet wheel witch sounded pretty good now I have a 6x6 66/88 compressor wheel with a t51r housing and that’s the loudest set up I’ve found I plan on trying your guys wheel next. I know this is all intake spooling noise nothing to do with exhaust noise

[@m.akbart3840]

😮very helpful.

[@sepg5084]

If a billet wheel is created from a cast billet instead of a forged billet, then the strength difference won't be that much. Cast wheels can also be machined to shape, if needed.

[@KCTURBOS]

True, but the main reason cast wheels are used is they are cheap to manufacture. If a company then has to machine the wheels after cast then that just increases the cost and defeats the purpose.
