So, what's the problem or better to say thing you do not believe with KB TS Kit cars? There are already plenty of them in this forum and elsewhere and they are fastest XJRs and XKRs. Is that some kind of problem?

WD/Whitecatt, you amaze me, if you consider this way of checking power is a more accurate way than 1/4 mile or dyno done right (even if you take out all the possibilities to cheat here, I can think of much more), we are indeed from a different planet, and I don't see a way we could come closer; so let’s just agree that we disagree.


I really can't see the point anymore to drag this on, this is more of hunt against my integrety then anything else (at least from Whitecatt).


Maybe if time permits this year I see if I can go to a drag strip as well, I would like to do it actualy, but it just isn't a common thing here Whitecatt, and your aproach doesn't stimulate me in doing it at all.

Laws of physics, I think I get you know.


Then this video thing would be a much better way of checking power by measuring the lift:

As I said before, good enough for me. Since there has been no articulated argument against this video showing what it shows with regards to the 0-100 time or that fact that the boost gauge stock reads 10, and mine now reads 18, the default then is that my claim has been proven.


How many HP do you think each +1 psi of boost makes?
Now multiply that figure by 8-8.5 and what do you get?

If you cannot answer this, then we all have our answer...

New headers arrived today for the other familial feline, the GT4 converted to a GT5 Poonterra

A nice set of wheels was traded for these "bundle of snakes" headers (snakes not completely installed yet)

2nd photo shows the fabbing up of a different wing, the stock huge delta wing has too much drag for those of us who aren't afraid to go over 60 mph.

Even in track trim, I could hit the brakes hard and still pull an 11 second 1/4 mile, but this baby is built for the twisties at full tilt boogie!

Geez I turn my back for 1 day & look what happens.

Don't let this thread turn into another pissing match about TS kits or heckling of forum members.

It's a fine line between having fun & trolling, some members have crossed that line here.

Now by all means carry on with that in mind.

Please look at this video. Great car with smaller KB, but not even dynod. The power is just enough for him without numbers.

I wasn't joking, keep it friendly or take it somewhere else. That goes for everyone.

180's first fire up - YouTube

First fire up
The motor was only running about 20 seconds before this video, but you can easily see this thing is a beast.

This is a stroked 408. All go, and still lots of show.

A lesser one just sold for $75K here to someone who, in my opinion, really overpaid. Occasionally a really nice one becomes available in the 35-50K range. This one will stay in the family for a long time.

The British Racing Green paint on this car was sprayed by "Images Auto Body" In Campbell, CA, who are famous for their Jag paint jobs, and the paint alone on the Pantera cost more than my entire investment in the XJR.

My brother, the real mechanic of the family, (I am just a hack), did this entire build, and probably has 1000 hours in this car, including time on the race track. We are not afraid to actually use it. HUGE 4 piston calipers, everything has been updated and improved. He did an A+ job.

But, time to bring this back to Jags: Here is the body shop's site http://imagesautobody.com/ lots and lots of STUNNING Jags to be seen here.

Default dyno cost-rental vs. own

Hi Avos,

It's been years since we last emailed. I hope all is well. Much has changed in my life (divorce/heart/etc..) but I'm finally past the worst and in the rebuilding stage. I've just playing with my Jag again. Rereading old threads I saw your comment on the tremendous dyno cost you've paid out over the years. 61 runs...wow!
That got me thinking about those bolt on (to the hubs) dynos. Wouldn't it save you money buying those rather than renting? Or are hub dynos not as good? It seems like it takes out any change of tire spin since their bolted on to the hubs. Plus they're easy to transport.

All my other runs (60+) have been the same dyno in another place (closer to where I live), where on average at start my stock car made more in between 310-320 rwhp din corrected (I never look at the uncorrected figures).

This was also similar on that same dyno with other 4.0 R cars I had tested there. My latest 524 rwhp was on that same dyno, and that isn’t the max you can get with the kit, that is not holding it back…

Just as a side note, If you convert this 327 number you saw to SAE for the environmentals shown, you would get about 326 sae net rwhp, so still close to the average you seem to come up with.

So, my dyno is not reading 10% high, you are incorrect.

But good to mention, I could have gone back to that 1st dyno for a higher reading; my last run would have probably been there 540 rwhp then and 650 HP. But I wasn't doing the dynos for others (have you any idea how expensive this is here)? This was for me to see what I could get.



Now 636 HP is still around 524 rwhp (assuming a 17% drivetrain loss), I have shown you the dyno. This was with just 22-23 PSI, I have driven already with 24, which was a noticable improvement again, and there is even more to get.


So, I have given the facts, and If you don’t believe this than that’s your right!


Now shouldn’t you ask similar proof from WD to show an increase of 100rwhp? I haven’t seen anything yet, or have I missed something?

After a 10.5 hr day and then going to work on my car (fix one thing and another pops up) I started reading this thread again. Somehow I missed your video Avos, lol.

Those breast each weigh in the neighborhood of a 12 pack of beer. So could the lift in her breast in inches equate to g force, which then one could covert to hp? If so, I'd much rather rent her out than a dyno as a tuning device...
