I noticed this on rennlist (NO AFFILIATION) and that is wasnt mentioned on this one.

Our Tuningkit for the 997 Turbo successfully graduated the first engine dyno course. Of the potential of the motor comfortably surprised a 1st achievement step with more than 400 kW / 540 HP . More to come

This will be available through Cargraphic when fully signed off.

Remember an RS Tuning 542hp 996GT2 does 0-300kph(186mph) in 28.5s (a Carrera GT takes 34.2s) and 0-200kph(125mph) in 10.7s - These are NOT chassis dyno hp numbers !"

I only expect great products from RS Tuning.

Thanks for posting Shaikh.

 

This what RS' site says.

Im not sure if i believe that number of the CGT going 0-186 mph in 34.2 sec. its goes 0-125 in under 10 sec and 0-150 in i think 15 sec. ur telling me that it take another 19 sec for it to go 36 more mph. NO WAY.

 

impressive, keep us posted!

 

There are sources out there for these acceleration numbers posted, here is one:

CGT Nardo test AMS 12/2004:

0-200kph (124mph): 10.7 s.
0-300kph (186mph): 34.2s

Sport Car Magazine 01/2004:

0-100kph (0-62mph): 3.8s.
0- 200kph (124mph): 10.2 s.
no data for 0-300kph but seeing the 0-200kph quite close (always above 10seconds) to the Nardo test, it would be in the low 30s as well.

Downforce and drag are not the CGT best friends, and yes a tuned turbo Porsche can blow its socks off.

 

10.2 to 124mph is pretty darn fast eh?

Off topic...heheh darnit at 10.7 seconds I was already doing 137mph What speed are you doing after that Jean? I think you posted somewhere.. I need to go back out to the track to see.

 

Sharky, we are talking about engines that live beyond the 5 k mile mark with the modifications on, you cannot compare your car!

The CGT has no turbos and the other runs at 1 Bar!

I am seriously aging waiting for your AX 22 run BTW, I am getting close to prostate cancer territory here.

That RS Tuning 997TT running 28.5 s to 186mph with its measly 540HP and stock weight must not be very far from the fastest lightweight GT700 out there...but of course we will never know, those AX22 that were part of the group buy seem to have disappeared

Just teasing you a little, you deserve it for going OT.

 

I'll admit that the 0-300 kph time does seem a tad long but keep in mind that acceleration into the high triple digits is highly non linear. In fact, the vel vs. time relationship is closer to a cubic polynomial due to the effect of aerodynamic drag. Its' conceivable in a race-bred car like the CGT that the stratospheric levels of downforce generated take their toll near the top end of its acceleration envelope.

 

I have only heard great things about thier products myself.

 

LOL of course I do The truth is I rarely drive that sucker anymore... First thing, I'm going to go try it at the drag strip again and that weekend when I do go I'll borrow someone's AX22 or something and see what it does 1bar? That's for sissies!

 

They don't seem to need more than that to kick the CGT's butt in a 186mph run!..

 

My GT700 goes 0-130mph in 10.8 seconds in 95f, I don't think that it would take me another 18 seconds to gain an additional 56mph

 

Sniff always picking on me. Just because I'm English too

I had a video of me going up against a CGT. Not very scientific but to give you an idea he pulled a little ahead from 40-50 and then I walked him all the way to 120 about 8-9 cars and then after that I really pulled him hard again... Again, who knows how he was shifting and on this one I'm going to have to go to data recovery to get it Was one of those annoying MAC (who uses those darned things anyways) quicktime formats and that HD is pretty dead. I don't have the original footage (wasn't my camera) so of course there's no proof darnit.

Maybe it was a dream

I don't know the right answer. But aerodynamics and heat soak play a MAJOR role the higher the speeds are, as RajTT mentioned.

The numbers that your cars are showing in the quartermile are sick fast, obviously the stock weight 540HP GT2 in question running a 1 Bar of boost and almost 200HP less, is not comparable head to head with your cars, but they can be closer than one could imagine.

In case it is of any interest, I compiled some data for you from the AX22 datalogs of a 996GT2 that runs a more modest engine configuration than yours, but my objective here is only to show the importance of aerodynamics and not compare cars of course.

(From a roll)

60-130mph (Delta of 70mph): 10.28s.
130-190mph (Delta of 60mph): 19.8s.

A speed difference of 70mph covered in 10.3 seconds vs. a difference of 60mph is covered in 19.8s at higher speeds!

Out of interest, that same GT2 covers 130-200mph (70mph difference like a 60-130mph) in 25.3s, which is 6.4 seconds to cover 10mph more at 190mph! That is how important drag and gear ratios are, fascinating stuff.

There is not too much reliable data available for 0-186mph runs out there, I just have a couple of them that are quite fantastic, the performance (torque and HP) really shows later on in the runs, much more than in their 0-100mph times, as a result of softer launches and tire spin (tests done on the street with street tires).
