Well, I don't tow often either.
I choose that ATT after reviewing all the job done by Tim and Dennis for testing and improving this turbo.
I'm not a racer too, but really, I appreciate a lot having the truck responding faster and easier at low rpms now.
About the sound, the ATT seems to be a bit more "quiet" than my previous GM-5, whistling less, though I can still hear it. But, if you look for nice rumble, believe me, you won't be disappointed.
I have a straight pipe with a silverline resonator, and most of guys think now I get a gasser.
It's hard to find words to describe the rumble : louder, more powerful, but at the same time not agressive. You have the feeling that this a the purr of a beast, feeling that behind this rumble is hidden a good source of power and torque.
Never heard a tiger purring, but that should be pretty close ):h
I gave my turbo the nick name of "Woa" : each time I start my engine for people to listen, they say Woa!, open the hood and show the turbo, Woa! again, take them for a drive, and Woa!
Thanks for that
Won't be long just not to be out of topic. Yes almost rare here, I know 4 only including mine with this combination of "light stellar blue metalic - code 27U" and "ultra silver metalic - code 96L"
I would not categorize it as a performance loss better described as a shift, with current fueling I get a puff of black smoke then acceleration on par with and slighlty better than GM-X somewhere in this thread is post by North Maine who rode in my truck when he was sailing on Chevron tankers near here and had a afternoon off, he did not seem to think there was a reduction in performance though I felt the shift myself, negligible IMO, would it mean a difference in a "hole shot" possibly, I don't race so I don't know, but I'm reasonably confident in a side by "long legs" run 2 6.5s with reflash-exh-etc. one with a GM-X and ATT the ATT would outdo the GM-X turboed.
and no I ain't paying for your engine if it grenades, you wanna play you gotta pay in the racing game, this turbo does well for what it is intended to do over 12k miles on mine, racing is hazardous sport if you are gonna R&D with an unknown as in 1/4 mile launched time trials there is some elememnt of risk; if you are serious let me know and maybe we can talk.
a possibility there Chris send me a deposit, and I'll send you my TDO7 after Bill is done with it, as that is only extra one I have, that one is most expensive turbo out there I paid for it twice, once when new, and a 2nd time to have it rebuilt when I filled it with expanding foam trying to make it safe to ship to Bill, of course that goes with caveat you broke it you bought it
