I had these on her 90 3.1l auto v6 firebird
we junked the car.
these worked well
definately gave a seat of the pants increase in power
improved gasmileage too
used to use these on long trips on the highway
gave some nice pep to the V6
made a nice addition especially with the AC on

never really had an issue using them.
been in the shed for about 4 years now

someone should take these
hypertech doesn't list these anymore
and they dont have a part number on the box
i had the belt i used, just can't find it at the moment
i think it was one size smaller (990 was the part number for the standard belt, i think 970 sticks out for some reason)
perhaps a call to hypertech can help

these are perfect
just have dust from sitting

i even used just the crank pulley, and left the alt alone, just slightly less power (seat of the pants feel)

i didn't have any overheating issues, but you might want to just use a lower T stat, i never did, used the standard 195 (180 would be perfect)

again, with gas prices higher now, this is a nice little goodie to have

have original box, no instructions or part numbers sorry..

i believe this would fit any 60 degree v6 of that era

i want $25 for it
shipped from zipcode 11784
probably about 3lbs total is my guess

it was a piece of cake to install, even if you just plan to use it for when you go out cruising

i have a high amp 170 amp CS130 alternator that might fit too, if interested, email me. it's brand new, but big $$

PM sent

i'll take them if no one has dibs on them. let me know shipped 70056

Matt

someone PM'ed me
sent some information
trying to locate the belt in the shed, if i do i'll toss it in
or at least get the part number off it

let me know whats going on ill take it if the first deal falls out?

I didn't think the site would ever be back up. I still want 'em...

Got 'em!
