Thank you @jgmblair , I took a bit of time before installing the power window accelerator, but now that it's done, I can really feel the difference—it's impressive. (At the same time, I’m replacing the differential, the timing belts (and accessory belts), the clutch, the suspension bushings, and rebuilding the brake calipers... plus a bunch of other little fixes.)
Still have a few sets ready to ship out and once they’re gone I’m done making these! Great upgrade and very easy DIY install. $225 usd Image Unavailable, Please Login
I got a set from jgmblair. Excellent person to work with, and excellent product. Before modfication - driver window 27 seconds up, 7 seconds down after - 7 seconds up, 4 seconds down. i suspect the window motors are untouched from the factory in my 87. interior may be next winter. hoping to actually drive it this summer!
Hi @jgmblair , I would love to get a set of these if you still have one available. Finding it difficult to DM you (something something not allowed), could you send me a message, and I'll respond ? Thanks!
4 sets left, this is a fun DIY for any owner Price is $225 usd plus shipping which ranges from $20-$30. Just shipped a set to Switzerland Image Unavailable, Please Login
Hello, I would like to buy one if still available. I am located in West New York, NJ. How do I get in touch with you? Please, contact me and I will respond. Best, Inmong
Hello Jeff, will they work on any early 70's models, Alfa Romeo, BMW, etc.? If yes, I would like 2 sets . Please PM. Thank you. Regards, Alberto
Hello Alberto, These are specific to the Testarossa as they are plug and play with the factory harness. Sorry!
Thank you Jeff, but the system (in practice) ought to be the same, even if not plug and play? Regards, Alberto
The "concept" (of adding relays, controlled by the window switches, to supply the large window motor current) can be applied to any car that presently puts the full window motor current thru the window switch contacts, but I'd think that it would be very unlikely that using/modifying this TR-based hardware would be the best thing for you to start with on a different make/model car (even though you would use the same relays and the same wiring architecture). If you'd like to better understand the concept, this thread explains how it is done on a TR and shows how it is wired: https://www.ferrarichat.com/forum/threads/tr-slow-window-fix-adding-accelerator-relays-at-c1-and-c9.663123/
