SINGLE v TWINS-LOW-BUCK, 1000-HP TURBO TEST

FULL RESULTS. Low Buck, Ebay Turbo Test, single $163 turbo vs twin $163 turbos. Also, low-buck twins vs single (Big Buck) Borg S480. Max Data-Boost pressure, Back Pressure and Charge Temp. Did twin turbos cut back pressure in half? Can low-buck EBAY Turbos compete with big-buck Borgs?
Can the BBC 454 make 1000 ho with twin $163 turbos?

I'm addicted to your videos... Such an underrated channel...

This is literally the only video or document that has genuine data showing why twin turbo may be better.
I see almost no one talking about back pressure.

This channel literally answers the question of:
Is SINGLE or TWIN TURBO better, and the answer is very situation based:

More responsive single turbo can be better than less responsive twin turbos
A single big turbo may be worse than twin of the same turbos at the same boost, for both longevity and power.
A bigger but more responsive single turbo may provide outright more power everywhere and be more responsive everywhere than an incorrectly sized twin turbo.

This channel is an absolute goldmine of information.
Thank you for making these!

There's more info on this video than an entire turbocharger book. There was a day when no one would share this detailed dyno test, thanks for posting Richard!

[mannieecker]

Richard, you are sharing an amazing amount of data with us and it is all good, solid credible info.
Thanks a ton for doing these vids for us as it is not easy to find this sort of information.

"THANK YOU!. "Richard your engine dyno videos/Dyno print out explained helps me take my mind off of me having cancer & my chemotherapy whatever reason when I'm in pain I put on your videos & I don't think about the pain..."THANK YOU RICH!

Love the work you are doing. Very informative. Biggest thing I noticed from twin turbos vs the s480 was the back pressure. That s480 has a lot of back pressure on the high end. To me, seeing how much less back pressure the twins had is very appealing to me. I would think a setup of properly sized twins would last longer on a motor vs a bigger single turbo.

Richard do a video on how to properly tune an engine please.

[ewaltsauto]

would love to see that test on a 6.0L LS

Found this channel a few weeks ago and it's addictive. Real world testing and proven dyno results can't be argued with. Thanks Richard your doing God's work!

[timbenks]

I swear I get more hyped every time I watch another one of you videos, finding your channel has been the most exciting thing that’s happened all week, keep the amazing content coming Richard 😁

[christophercasey]

This channel is going to blow up really soon. Better yet, its gonna be crawling with people having intelligent conversation and seeking improvement. Finally.

[MLFranklin]

I love so much about these videos. One cool feature is when your boost pressure is higher than your backpressure, your pumping loop (from the PV diagram) adds to the power rather than subtracting from it.

[tngtacticalmiata]

So, properly sized single is the way to go. Less complexity, less points of failure and the same power and response. duly noted. Thanks, Man!

[tensixtythreevideo]

Bro you got the best channel on YouTube. My new favorite!

[ajjskins]

Richard, could you do a vid all about cylinder compression ratios, octane numbers, and timing. Its the background content that ppl dont know about boosted motors and performance builds.

[GlobalMediaInc]

Been Waiting On This One! If Possible, Can You Do The Same Test On Any Small Block LS? Preferably A LS1 Or LS2? Great Video!

[marcstlaurent]

Thanks again Richard for more great content I don’t see anywhere else . I’m a big block guy and loved it, I run two 369S Borg Warner’s and make tons of power at 6800 with big torque instantly all through a CSU blow through ad I haven’t made the jump to EFI yet .

[SloppyMechanics]

You need bigger injectors? I know a guy ...

[stacekirstein]

Thanks for doing this test! I asked for a twin vs single test and you did it -cool! I was surprised that the curves down low were so similar, I would have thought the twins would have spiked torque early in the lower rpms - very interesting.

[kylemilligan]

Fantastic tech Mr Holdener. Thankyou😁 The $850-$1000 on3 94mm and 107mm turbos would be very interesting! A 427 ls corvette made close to 1300whp with the 107mm here on youtube
