That's how I'd describe mine but I'll keep an ear out for da slappinMine has an e-cam and it sounds like I have a bad idler pulley at idle. very little whistle which I really like - completely low key. vortech says it is gear backlash noise, and some folks on the interwebz say it gets whistley-er as it breaks in.
You didn't hear the following from me...Put a smaller pulley on it. That will spin it faster then it will whistle more at idle. And,,, it'll make more boost.
Very true about the warranty. Put an 8" crank on it and let er fly! Its better to do it that way(better belt wrap) less likely to slip. Seriously though. I remember when my old sc-trim was new it sounded like a can full of rocks at idle. It wasn't too long it sounded better with a nice smooth whistle.You didn't hear the following from me...
If you change the blower pulley, you void the warranty. If you change the crank pulley you don't... Food for thought
My Vortech V-1 S-Trim was the best idling blower ever. It didn't have a grinding noise at all, just buzzed loud the entire time. We put a V-3 on a buddy's FOX and I thought he forgot to put the oil line on. Nope, that was the stock sound.
Can always go turbo.
My a trim sounds like a cat got sucked in i love it !You should have heard my old A trim. Straight cut gears. Pulleyed that sucker up to almost 10lb. LOVED it
What was the power difference between the 4 and 7 psi? I don't believe I'm going to get a new pulley today, I called to sched a tune and they couldn't get me in until Sept so I have a little time I guess.Very true about the warranty.

However, only a month into owning the blower I upgraded the stock 6 rib pulley settup (voiding the warranty) to an 8rib 3.33/6.87 kit, and discharge tube with bypass valve.
Went from 4 to 7 psi, then a 3.12" pulley @9psi,,,, then 2.95"@11psi,,,,,
Yep I had the fever. LOL
Roughly- every # of boost is about 10hpWhat was the power difference between the 4 and 7 psi? I don't believe I'm going to get a new pulley today, I called to sched a tune and they couldn't get me in until Sept so I have a little time I guess.

Outside of Dallas, TX actually. The shop that's gonna do it kinda has me by the short hairs. Since they've tuned it before its cheaper to go back to em than it would be to go elsewhere, its usually around $250 or so. What cylinder heads were you running when you made 312?September? wow, where do you live? We could get it tune tomorrow at my buddy's shop here in Dallas GA.
