Turbo noise?...
For you tt guys making over 600 RWHP...
Is there any noticeable compressor/turbine noise at idle, cruise at 40, cruise at 70, WOT acceleration from stop?
I've had a Vortech, ATI P1/D1/F1-and their idle and low speed noise is objectionable to me. WOT blower noise is not an issue-just idle and off idle low speed.
Please let me know your experience.
Thanks, Roy

I must be getting old, because the idle/part throttle niose of my Procharger was really starting to bother me :o . Was your Vortech an "SQ" head unit? I thought they were supposed to be very quite.-Ken

Roy, I have the Vortech and have found that I really have to listen from inside the car to hear the blower at idle. If you do hear it, it sounds similar to a jet airpline idling at a distance. At WOT the engine and exhaust overpower the blower sound.
I heard a LPE 427TT once in person and would not have even known the TT was there if I hadn't been told.
Maybe it is time to try more CI instead of FI. Have you considered a 441?

I run the TTi X kit along with Borlas. You cannot hear the turbos at idle. Even cruising around they are very quiet. At WOT it just sounds like a lot of air is being moved.

I checked the Powerdyne which had a conventional internal drive V-belt but it did not have the capacity and I think it's discontinued.

Turbo whine...

I guess the only huffer quiet at idle and low part throttle is a Turbo.
That makes my discision...Turbo it must be!
Thanks guys for your help and comments!

you wanted to put Andy's new TT system on. As if
you hadn't already made up your mind about going
the turbo route.
Here is a little more reassurance for you

At least this describes my car..well until it spools. I wish there were noise....I don't like hearing the sewing machine drivetrain noise made my the Xer lobe.
