Yes.
NOS is a good way to melt your motor unfortunately. If it wouldn't cost a fortune, I'd have the pistons and head chambers ceramic coated and add NOS (and some "other stuff") to the performance picture. Then again I'd lower compression somewhat at the same time - so it'd become a money pit on redoing the bottom end. Without that heat barrier I will stay away from NOS and chemical brews in the XKR.
(I'm in the chemical business and I've run stuff though cars you wouldn't believe - nor would I advise messing with. Once you get into chemicals it's just a matter of how much heat and pressure you believe your motor can withstand and how much hammering your drivetrain can take.)

What an incredible product.. I am 110% in if you guys are getting a group deal... I have all sorts of plans and with having re-opened my siding business recently.. will be able soon to afford all sorts of goodies and upgrades.
One thing i am very interested in is a twin screw charger if it can be done on my 1996 XJR.. or if someone has any templates to port my factory one. When i was heavily into rotary engines i was able to buy a p[ort template for my rotor housings and do the porting myself.. which was that much more enjoyable when you felt the power increase after the breakin.. (okay okay.. I kicked it like a kid on the second trip out of the garage.. but then was good for the next month and a half .. )

If you go the port route, I think a few members here have gone to Stiegemeier. For the twin-screw, there's EuroToys. There's also a member on here (Avos) who is supposed to be developing his own twin-screw kits and/or conversion parts, but I don't know if he's ready to sell them yet, so you'll have to send him a p.m.

Am actually ready with the Stage I kit for the XKR/XJR models, and am working now on the Stage II version.
Pending interest I can make a kit for the Stype (have already made one manualy for a Stype, 420 rwhp still without ECU tune, expect another 20 rwhp with tune), however it will take at least 1 1/2 month before I could start making a kit form that that one.
You can PM me for more info.

@Stypernut,
Mmhh wrong thread maybe as I am not working on n20 kits, but you are more than welcome (am close to Antwerp). I have specialized in replacing the roots supercharger to Twin-screws ;-)
PS It would be a relatively easy for me to diagnose your engine as I have all the tools, and I can let you feel the difference a TS can do (if it is dry weather).
