oh wow... what excellent timing...

my friend has just taken delivery of 700HP car from one of the most respected US tuners.

we're planning on a friendly rolling straightline race, complete with GPS mounted in both cars, and full video coverage.

he's leaving the country tomorrow, but rest assured this will happen.

watch this space folks

 

Hesperus,

This will be very interesting. I hope the roll goes all the way up from 30 to 190 mph or more, it will be interesting to see how the acceleration stacks up between RUF and the other tuner, whoever the tuner is, comparing the datalogs will be very interesting.

Eclou, BTW quite a few European tuners had already 550BHP kits in 2006 on stock VTGs and some of those go as fast as the 600+ Hp claimed out there even on the dragstrip.

The Manthey dyno test bet is on for any 600+BHP on stock VTGs.

 

Yes many other euro tuners had stuff out, but the Rennteam herd only worships from the temple of Alois. It seems that unless Alois sprinkles his magic dust on it, any other package is unworthy and unreliable, and only he can control the spark flame with telekinetic powers. I don't doubt that all of the tuners are probably within 10-15 hp of each other, since they are all running similar max boost (1.2 bar). As you know beyond 1.2 the VTG is going to be pushed too far into inefficient zones and the heat will be an issue.

 

Realistically, given the limitations of our roads here, it wouldn't be safe to run two cars simultaneously to much beyond 280kmh. i've seen cars go over 320kmh, but those were solo runs.

i actually have they dyno chart of the other car-- its very impressive! however, let me ask the owner if he's ok with posting the chart here, and other information about the car at this time. but rest assure, when the run happens, all information will be disclosed.

this is in no way a grudge match; he and i are very very good friends, and while we both are hoping our respective cars "win", in the end we're excited to do this and document this for the simple reason that it is fun and to our knowledge, there hasn't a video/test (i.e., blue chip US tuner vs blue chip euro tuner) of this sort anytime recently.

 

For the real world record: My car currently has stock VTGs - other than that she's been upgraded with Evoms 690R -kit with all the bells & whistles. On our anti-economy-driving course from Travemunde (harbour) to the Ring it was proven that 997TT with EVT-690R* is performance wise on par with 996TT with Techart Stage 2 (& yes, once again, all the bells & whistles here too). We did several runs varying anywhere between 80 km/h to the 300+ km/h figures and there literally is no difference in performance with these cars.

*should I say EVT-610 kit here since all the cars were using same 98 RON propellant?

During the tuning process I've kept record for 60 km/h - 100 km/h and 50 km/h - 150 km/h spurts.

Stock with overboost
60 km/h - 100 km/h 1,6 seconds
50 km/h - 150 km/h 6,2 seconds

After all 690R -parts had been installed these figures were reduced to:

690R with overboost
60 km/h - 100 km/h 1,5 seconds
50 km/h - 150 km/h 5,0 seconds

Kaizu did the same runs, but this was different night to my runs, weather was crappy and circumstances were at least debatable:

60 km/h - 100 km/h 1,7 seconds
50 km/h - 150 km/h 5,6 seconds

Once my house building project, office & family allows me some spare time, I shall test with locally available 103 RON Racegas and see what happens once ECU gets used tot the 103 RON. Ordinary gasonline in Europe is 98 RON. Hopefully this will happen before the winter months. Other rather interesting comparison should be friends 996TT GT700.

With my experience 530 hp == 610 hp. :-) I guess I'll have to wait and see once GT2's bigger fans become available... Then again - WHO does need >500 hp?

I guess we all do!


Thought about this but eventually didn't have heart to do it. I would've been more interested in max hp with regular gas - not with the racegas. Besides - where do you get Racegas @ Adenau? I looked around with no luck! My butt-dyno says there is 550 at the moment. Unfortunately/luckily there's no printout for this! :-O

-ESu (still on four rubbers)

 

European tuners are reliable, but they produce much less power for much more money than American tuners.

 

I would tend to agree with your estimates, here is another example,

FVD 555BHP with stock VTG based on datalogs:
60 km/h - 100 km/h 1,5 seconds
50 km/h - 150 km/h 4.5 seconds

The only place you can get race gas is at their racing workshop (across the street), but do not expect it to make any difference on that dyno.

 

Hi Hesperus, any news ?

A 700HP 997TT should put a 3.5 second 50-150kph run most likely! Looking forward to it.

 

my friend is back from his trip... car's just being checked... hopefully within the next 2-3 weeks we'll have something

oh, and his car is a 996TT, not 997...

 

Ive done a bunch of dyno runs on the 550 engines, they usually post dead on, theres obviously some differences of 5 hp or so, but never an underestimate of 50 hp. To be honest i think your 600 kit probably 550 hp

 

A 550 hp 996 TT will not trap 134-136. No way. But I guess possibly when it was the 600 kit a trap speed would help
(although elevation plays a huge factor).

 

with major weight reduction

 

Great post guys...so here's the question from a novice on tuning. With such varying points of view on this subject, I would be interested in your opinions on how to tune my car to:

1) signifcantly reduce lag
2) increase power/speed = thrill factor
3) maintain daily drivability
4) maintain my warranty
5) get the best bang for my buck

 

for all we know the guy had the 590 hp kit and just lied and said he had 550...

 

+1. usually the ET at the end of the drag strip is a good indication of HP!
