Alright guys hopefully someone has an answer I have a 2.4 Kenne bell running a 3 inch pulley. 17 psi with headers. Car is not whining at all, not a single bit may sound stupid but that’s priority for me. If anyone has some feedback is appreciate it .

Bypass valve stuck open maybe? What’s your boost gauge registering? Was it whining before and now it isn’t? Is it making good power?

No I’ve checked it’s fine, boost goes perfectly with open throttle. Makes good power. Doesn’t have any issues. Drives me crazy looks like I’m the only Kenne bell owner with no whine...LOL

I have a 1.7 KB on a 99 Cobra and it never has whined. It has run good for 18 years.

Isn’t whining a sound of inefficiency? Sounds like you have a good running unit. Make your car quieter, is your exhaust too loud over powering the engine noise? My friend has a kb cobra and a really loud exhaust and you can’t hear his blower whine either.

I wouldn’t think I’m running 1 7/8 headers with a 3” x pipe restricted with a 2.5 bassani catback is not too loud tbh.

My 2.8LC doesn’t make an audible whine in car... but 1 3/4” Kooks into a 3” off road X and 3” Bassani is the reason why!

Yep, long tubes and cams, little to no whine from my VMP. My ported stock blower with long tubes didn't whine as much either.

My gen2 2.3 whipple is very quiet with a 3.0 upper on the pump gas tune....it is completely different with the 2.6 upper on E85. It whines loud. Sounds awesome.

The loudest whine I've heard was from a 2003 HD F150 we put a 10lb lower and ran E85. That truck's eaton was insanely loud. Scared all the blue hairs at the grocery store parking lot as we passed by LOL

I'm with the OP on this one. SC's gotta have some whine! My 2.3L Roush SC peaked at 26.4lbs of boost (verified at the last dyno session) and whines like it's gonna blow up and that's the way I like it, LOL.

That has to be a huge lower pulley.

Ya it was, looked like a pizza. That truck was amazing, so simple. 80lb inj, fore hat, 2 gss342 pumps, factory lines, 10lb lower, factory upper.......E85 tune by 04sleeper. Ran 12.7s at 107, tipped the scales over 5600. Those 4 door HD trucks are very nice cruisers.

Kenne Bell is quite by design. From thier website: “Whisper Quiet. No embarassing, annoying noise.”

My 2.1L is hardly noticeable.
