Ive received my vortech non revup complete kit and everything is there and I have questions
1) reviewing the instructions i dont see anything about assembling the cog belt idler pulley so any pics or diagrams would be greatly appreciated
2) i have the Paxton black box as mentioned i the instructions P# 5A001-353 BUT...
I also received a larg black carton labeled Unidchip with a hand written sticker 5A003-350 containing a Q+ 0148D silver device and a slighty larger black device with no real model number except it has unichip PNP technology. There is nothing about the unichip boxes in the instructions but they themselves came with instructios.
do i use both systems ? or just one of them ?

what makes vortech best in your opinion? im seeing some threads popping up about the need to use better quality bearings than what the units come with stock here and there. im planning on using it for a track only car so a good rebuild and some preventative maintenance now would be crucial. does anyone here exp. with 928M, JonBondPerformance, Superchargerrebuild.com?

My only concern with the potential reliability of the Vortech has been the effect of blipping the throttle on downshifts and/or using a 2-step. Vortech specifically warns not to free-rev the engine or damage might occur, and it seems the majority of Vortechs are used on automatic mustangs, so it's always kind of nagged in the back of my mind that proper heel-toe downshifting might not be good for it. Whatever though, I'll rebuild it if I need to.
I've got 43,000 miles, lots of hard runs and Drag racing on my Vortech. It's a 6 speed and I rev it all the time. I've never had a problem. I'm making over 18psi and rev it to 62,355rpm

I would be much more comfortable having 928 rebuild my blower than Vortech. Their CS is terrible, they don't back the product up, and the overall quality control is lackluster at best. All in all my dealings with Vortech have been terrible. The only good part is they actually make power.
And never buy a V3 if you can avoid it, they are ****.

I've always done the rev matching type of downshifting often most every time I drive the car pre-vortech and for the 2+ yrs. since; never read that about possible damage before and I doubt that I'm hurting my powertrain or the blower. Drove 2 280's and a 911 for years (non-boosted) exactly the same; was taught that many yrs. ago and it's just natural in my book.

I'm not worried about anything outside the Vortech head unit (and I'm not exactly losing sleep over this, it's just something I've wondered about).
We're in agreement: In the 20 years I've been driving, I've driven everything I've owned that way as well. Heel-toe was one of the first things my dad taught me, and was reinforced with a Skip Barber 3 day school back in y2k- but there we had to double clutch too. It is just the natural way a competent driver operates a manual transmission.
My thought is on the stress on the impeller bearings that accompanies rapid changes in angular velocity. Large acceleration values involve large force values. Like meanz said, it's probably nothing to worry about and vortech just says that to cover their asses. Still makes me not want to even try a 2-step though.
I will say that I like how the car actually drives much like it has a light flywheel with the Vortech. It will rev faster/blip easier AND the S/C drag slows the engine down between shifts much faster.

I suppose the uprev version of just pulling timing until the engine can't spin any faster is more of a soft than a hard limiter and is probably closer to your cruise control analogy.
Anyway, it's a moot point now thanks to Timrod.
