Another Avos Twin-Screw Supercharger Kit in USA
It's good to be back home!
The techs at Falconworks had a heck of a time with the stainless steel braided hoses that were custom made. The hose maker messed up by using the wrong fittings twice and they leaked upon installation. The newest set arrived today. If they don't leak, that will allow Bill to take the car for its first test drive today since the installation of the new lower springs, differential, blue-top solenoids, exhaust system and big brakes.
Polly (Falconworks' office manager) sent me these pictures a few minutes ago.
When they installed the newer Victory tail lamps for me, I had them remove the chrome trim ring from the lenses. I like the way that they look without the chrome trim.

This photo shows how the big brakes look at the rear:

I really like how the car looks with its new lowered stance and big red brake calipers. Aw YEAH!

It is currently being test driven. It looks like I can take her home! The video is a quick shot of it pulling out for the first time with tech, Bill, at the wheel.
I am posting from Falconworks right now using a smart phone. Copy and paste the link to see the short video.

Just have to add after seeing the video, how good the lowered effect has enhanced the way the wheels look with the car. They really fit the openings well and look great.
Are they offset as well? Maybe pushed out a little?

It got late here and I have an early morning meeting. I finally got to take it for a drive without the fiancee in it. Hah!
The shifts are mind-blowing fast. The handling is like a race car's... VERY flat in corners. OMG. The exhaust sounds bad-***. The rear end HOOKS UP with that new differential. This thing is GLUED to the road.
Thank you to so many that came before me to offer advice and post on this forum about how to do things and what parts to consider. Thank you, Falconworks! Thank you, AVOS!
I feel like I just got a shot of testosterone.

Thanks Jeff, now it’s enjoying time again ;-)
One word of caution, by having the lsd, and a smaller upper pulley (so more extreme than the max recommended), 1st gear take offs are very hard on the diff bearings. Mine just need replacing after 45Kmiles of which 30Kmiles with the same small pulley as you have now (and using very sticky Michelin Super sports295 wide ones). This included many 1st gear take offs as they are just so much fun, but also taxing…

Jeff,
One more thing, I think the CM12 nozzle is way to big. Am using now 3 x CM2 nozzles and see still a very rich mixture (am using 50/50 mix), so the CM12 may work against you in terms of power.

Sure, but I am talking about mid 11... If I get small things better, Sept 29th will run into 11. Let's see.

Thanks for the advice, AVos. I'll try a step down to see how it goes.
I'll so a 1/4 mile run at the strip this fall. It is still really hot here!
I did some more ripping around this morning. The handling is incredible. I'll get a chance to do some video soon.
It's time for a new signature photo!

Just spent (won't say wasted) a sunny morning reading this entire post. If I were a smoker I'd need an "afterward" cigarette. Thoroughly enjoyed the contributions, and of course now I want to modify my XJR even more than I did.
Nice work Jeff. You are fortunate to have the craftsmen you found to do the work (just have to see the way they keep their shop to know that they take pride in their work) but they were probably quite happy to have a client that was willing to spend the time and money to do it right the first time.

Yep! It turns out that there is a dyno available about 3 buildings away from where I buy my tires. I will have the XKR put in a run sooner, rather than later. It's still pretty hot here, and I want the temp to be no higher than 90 when I get the run. Perhaps the next week or two will provide that opportunity. I don't mind going in the morning, but I've been sick with a nasty cold lately, and want to be lucid for the event. =)
Cool I cant wait to see the figures.
Do you still have the water/methanol kit installed? It might be good to do several dyno runs, at least one with and one without it enabled, just to confirm what its actually adding.
It boggles my mind how injecting water/ethanol into the intake can add power, especially with a twin screw SC as its not cooling as much since the compression of the air doesnt get it as heated as it would with the stock rootes-type SC right?
Also the fluid would be taking the place of some of the gasoline going in, and water cant burn. Can someone take a shot at explaining it please? Does steam instantaneously expand more than heated air or something?

11sec time is waiting for you. I guess you need just a pair of drag radials.
