LET'S TALK TECH-KENNE BELL SUPERCHARGER TECH

HOW MUCH POWER DOES IT TAKE TO SPING A KENNE BELL AND SHOULD I DO A VIDEO COMPARING VARIOUS BLOWERS FOR POWER CONSUMPTION AND FLOW AND TEMPS?

[@Luca_____355]

Yes release all the data, more blower tech the better!

[@chriswilson8493]

Yes would absolutely love to see more data about how different superchargers compare in efficiency, especially between other twin screw but also in other supercharger types.

Morning for you ,End of day for me here in France . I will try to understand something with my poor level of English ,😉

[@mboost3151]

Thanks Richard. Would love to see some PD blower/intake temp comparisons for KB, VMP, & Whipple on the 03-04 cobra 4.6 mod motor

[@jaydubb71]

Matt had a tuning course I took in 2012. Good info. He might still have the videos from that course available. I'm actually in the video. Lol

[@Luca_____355]

Interesting comment on KB having a more efficient/better rotor design than Whipple. Didn’t know that!

[@rocknrollfishinpole]

I would like to see a junkyard d15 with ring gap , better intake, and header. There is a better stock honda intake than the d series one. I dont know which one. Im sure you do. I think this would appeal to alot of people and get many comments.

[@richardholdener1727]

a d16 makes more power

[@rocknrollfishinpole]

@@richardholdener1727 I dont have a d16 in my crx and alot of people have d15 engines in their cars. If i wanted to do an engine swap i would go with a k20 or 24.

[@richardholdener1727]

I thought you wanted me to go get a D15 instead of a D16-you just want data on the d15

[@chrisdeli7547]

From my experience 10-12% losses for the roots type a bit less for the screw type 8-10% especialy at higher boost they are more efficient and for the centri about 5-6% . it depends mostly at belt width length weight and tensioner for the losses

[@richardholdener1727]

the belt does not determine the design or power consumption differences between the three blowers

[@chrisdeli7547]

@@richardholdener1727 i didnt express it right every blower is about there but the losses of each one depends on the belt weight design tensioner. a 4 rib belt without a pulley tensioner 1feet long will have less losses than a 6 rib with a pulley tensioner 2 feet long since less weight/inertia friction of puley bearing during acceleration for each given blower

[@utahcountypicazospage5412]

The most awesome beef was kenne bell vs VMP

[@richardholdener1727]

I don't think VMP makes blowers, they use Eaton rotor packs

[@randywilliams9531]

Could you over drive them to lower pressure. Change pulley sizes to get the boost levels you want and not change the amount of power you need

[@richardholdener1727]

spinning the blower faster produces more boost

[@malbirrell]

How many hp does exhaust drive pressure cost on turbo applications ??

[@richardholdener1727]

VERY LITTLE

[@ClaytonYatescarenthusiast]

Im still a little curious how a blower that required 100 plus hp to drive at even high boost levels wouldn't have added any power to the ls3. Even it it lost hp would it gain 100 ft of tq just off idle cause the blower is so small and only efficient at very low rpm on huge motor in comparison. Or pulley it way up or way down depending on pully location and spin it to max blower speed at 3000 rpm and then stop the run.

[@richardholdener1727]

what blower required 100 hp drive and didn't add any power?

[@ClaytonYatescarenthusiast]

@richardholdener1727 at 15 psi you said Kenne bell said it required 100 plus hp to drive at 14000 rpm so I'm assuming restricted pretty heavy. You restricted to a lower psi and made what 5 psi of back pressure and used estimated 40 hp to drive. In that video I asked why not hook it up to the tb and tune it. See what happens. You said a blower that small ain't adding in hp to a 400 hp ls. I agree but why not see what it does underthe curve, low rpm and spinning it harder to see what happens?

[@richardholdener1727]

THE BLOWER NEVER HAS ENOUGH FLOW TO SUPPORT THE NA POWER LEVEL OF THE 440-HP MOTOR, AT ANY RPM
