Rocketsports to launch Jaguar XKR GT2 - Page 2

yes, champcar was doomed from when CART went bankrupt (actually, probably from when Ganassi did Indy) and at least ChampCar's teams got a fair deal when the 'merger' finally came, albeit a bit late for them to really prepare for last year.

ah, damned no editing policy. If I could change that I would because this isn't the place for that discussion. Great news about Jaguar, although I believe they may struggle to secure an LM place next year - there's the potential for about 10 automatic selections from the various series that count, not to mention Corvette and GT1 winners being rumoured to be able to choose their class for next year, so a new car and team may not be sufficiently qualified in the eyes of the ACO. The Jaguar name, of course, is the one thing in their favour.

hey J A G,

The car sitting on the pole for tomorrow's Trans Am race at Virginia International Raceway is the #6 Pickett XKR... some other shoe is driving, but that is a Rocketsports N/A build of a stock block 4.2 L Jaguar engine.

Interesting that neither the existing or the proposed engine programs are supercharged. Reliability concerns perhaps? Apex went that route, and had induction temp problems...I looked around for their Euro GT3 results, but only found a few in '07-'08. Unimpressive, and no details. Anybody know if they finally made consistant power with the S/C engine?

Even with Jaguar Engineering consultation, apparently Rocketsports doesn't think it's worth a go.

So far the Apex Jag is very disappointing.

Bullett · 19 Apr 2009, 11:27 (Ref:2444592)

Awesome news, hopefully this brings Jaguar back properly to GT racing as the GT3 program so far has been disappointing...Can't wait to see actual pictures of the car!

I think the initial Apex XKR was built to a price and the spirit of GT3, but soon found itself up against far more developed cars, even Porsche's 911 RSR struggled.

A race prepared V8 like the XKR's should have no problem putting out 500bhp+ without the supercharger.

Hope it has plenty of horsepower without the supercharge. Would be fun to see another competitor in GT2

love another car, especially a Jag, in the series as long as Paul G. doesn't try to buy the ALMS.

JagtechOhio · 20 Apr 2009, 01:35 (Ref:2445106)

Hey JAG,

Rocketsports states 650 HP, that's the 4.2 Jag block punched out to 4.5, normally aspirated. That's what was on the pole at the VIR Trans Am, until they failed tech for a spoiler 1/8" too high. So the #6 car gets to charge all the way through the field from the back. No race results yet, 5 XKR's in the field.

So now Rocketsports is carving on the new 5.0 block, which Jag says is stronger and a bit lighter. Maybe 700 HP normally aspirated?

Aren't those specs for the Treans-Am car and not GT-2? And is there not a thread for Trans-Am?

L.P.

JagtechOhio · 20 Apr 2009, 03:21 (Ref:2445145)

"Scuse me, I was answering a previous poster's question, The GT-2 car will be a 5 litre. And since neither it, nor the engine is in existance as far as anyone outside Rocketsports knows, I guess I don't have anything else to talk about.

Why not? Then he could be champion! I love the car, but have mixed feelings about the team.

Before the restrictors which will bring them back to approx 500bhp, but with good torque like the Corvette.

In GT2 they also have the option to run a higher minimum weight in return for larger 14in tyres, as opposed to 12in, and a little more power.

The 911 RSR runs to this spec.

JagtechOhio · 20 Apr 2009, 17:55 (Ref:2445721)

Thanks JAG,

It's all about learning, and I'm looking for relevant technology to use as a guide for potential street car adaptation. There may be no connection, other than to encourage Jaguar owners to develop a better sense of brand loyalty.

14 inch wheels? The standard on the XK/R is 18 inches (I actually run 20 inch wheels), and that's the same used by Apex on the GT3 car.

Steve, as he said tyres and not wheels, I believe he is referring to width not diameter. Art. 13

Phew - I was getting worried!!!!!!!

JAG · 21 Apr 2009, 15:29 (Ref:2446386)

What makes me think they'll run the wider wheels are the pictures showing large wheel arches like the 911 RSR, plus the XKR may not get down to the regular 1150kg minimum weight.

I don't think we should take what we saw in the renderings as set in stone. Who remembers the original Aston DBR9 photoshop?

Running wider rears might be a good strategy if removal of excess weight is deemed too expensive.
