    Ruf Turbo innacurate vbox results??? please help

    I tested my Ruf turbo in with the perofmance box and was a little bit dissapointed and the 100-200 results dosent seem right..

    0-60 1.7 sec
    0-100 3.4 sec
    0-160 7.2 sec
    0-190 10.1 sec
    0-200 11.3 ??????? how can that be ?? it needs 1.2 seconds to get from 190-200??? i feel that this is innacurate

    also my 100-200 times are like 8.0 sec , 8.1, the best was 7.7 sec so far??? temp was 22 degrees

    Boost was consitantly at 1.2bar and dropped to 1.1 for a second in third then back to 1.2 for the rest of the run

    i feel that the 0-200 times and 100-200 are innacruate
    please help me..

    My car has Ecu, Ruf Exhaust with 100cel catylics, Bmc airfilter & intake plenum..

    Btw External antenna was used

    Re: Ruf Turbo innacurate vbox results??? please he

    Can you post a screen shot picture of the graph showing the acceleration speed v time and longitudinal Gs and height please ?
    This may reveal any problems....

    Here is my best run for 100-200

    Re: Ruf Turbo innacurate vbox results??? please he

    Well firstly I guess it is a tiptronic since there are no gearchanges on your graph ?
    It probably weighs the same as the Ruf which RC tested ie 1620kg.
    Did you have a passenger ?
    You are about 0.5s slower than the time RC got - this could be down to any of the following:
    Road surface
    wind
    fuel
    air temp was 6DegC higher than RC test so you will be a few hp lower.

    7.7s is still pretty fast, I do not think you have any problems - Looks like the IPD plenum is certainly not delivering its extra 40hp

    Re: Ruf Turbo innacurate vbox results??? please he

    7.7 is about what my stage II manual car would run on 93 octane street gas for a 100-200kph. It drops to 6.6 seconds on 104 octane fuel and the "race" programming. Try a higher grade of fuel and see what happens

    Re: Ruf Turbo innacurate vbox results??? please he

    yes im running 97 octane which is equivelnt to 93/92 in the US, No passenger but my weight is a little high more like 1&half passenger ,it was a little bit windy,and road surface was not that great and btw i got 7.7 without using the kickdown and it was about my 8th run from 100-200 experimenting with manual and auto mode, with kickdown its more like 7.9 or 8, for the intake plenum i do feel that the car is more eager to accelrate from standstill and revs more freely theres definatly a gain but maybe not by much, maybe 8 or 10 hp, by any means this also might be due to the humidity we have here i have already smoked a 620 hp M6, a z06 with intake and headers and a 997 GT2 by a car length and slowly walking away, so i dont think there is a problem with the performance

    I used to run 7.2-7.3 when the car was stage 2 using 95 octane (100/91 mixture). 7.7 is very acceptable I think with pump gas and in 22 degrees C.
    Like Gene said, try some 100 octane or above and I am sure there will be a big difference. Tuned TTs love high octane gas.

    Re: Ruf Turbo innacurate vbox results??? please he

    6.1secs with 650hp (manual). Two passengers, full tank, 40k luggage, 98 oct gas. The dyno run shows crack hp not at the wheels. I think 7.5secs+ is kinda slow, try again in different conditions with better gas. Then give Ruf a call..
    If there is sth wrong picked up by the ecu (detonation, high EGTs or anything really) the ecu compensates with dramatic consequences to performance. Had real life experience with modded stock exhaust and modded vtgs. When I changed to CG and also added ICs the car instantly gained hugely in performance..

    Re: Ruf Turbo innacurate vbox results??? please he

    GT, do you think if the ecu is picking up something wrong i can see what the is problem via an OBDII scanner like actron

    Re: Ruf Turbo innacurate vbox results??? please he

    Don't have any experience with this but I ve heard that if you know where to look you can pick up all those relevant values.. I would call ruf and tell them all this (that's what I did when I had a problem). Fyi my car went 0-200kms from 11.2sec or so to well under 10 seconds when I corrected these problems which is huge. What the hp rating of your car?

    Re: Ruf Turbo innacurate vbox results??? please he

    My car is rated at 550 Hp, also if there is a problem with the egt or anything it should limit the boost right? not boost 1.2 Gt may i know what problems you corrected?

    Re: Ruf Turbo innacurate vbox results??? please he

    High Egts mainly, and probably intake temperature. That was leading to the ecu increasing fuel consumption (a lot!) and reducing ignition timing as well. The car felt really lazy and even though it was rated at 600hp it was going neck to neck with a heavier 996tt cabrio with 568hp! The vbox showed 560hp at best which is consistemt with what TB993tt had described as potential power losses from the ecu retarding ignition timing in such cases. Could not see any difference in boost but then again the instrument shows up to 1.2bar while real boost was much higher..

    there is some thing wronge with your car .. my car is 560 hp from 9ff (ecu,exhauzt,headers) :
    100-200 : 6.5 s (2 shifts) 25 c`
    100-200: 6.3 s (1 shift) 25 c`

    Re: Ruf Turbo innacurate vbox results??? please help

    CGT my car did 0-60 in 1.7, 0-100 in 3,4 0-160 7.2 and 400m in 11.3

    these numbers seem right dont they?? its just the 100-200 internval.. it takes 10.1 from 0-190 and 11.3 to 200? more than a full second to get from 190 to 200 this sees very innacurate.

    Re: Ruf Turbo innacurate vbox results??? please help

    Guys, The octane rating in Qatar is equivelant to 92.15 US

    Is that 560 hp at the engine or at the wheels?

    how did you measure these numbers? this is RT12 650 territory.

    Maybe he switched the numbers '5' and '6' .

    Re: Ruf Turbo innacurate vbox results??? please he

    my stock turbo (only BMC Filter) did a 7,5s 0-200km/h with driftbox and external antenna. I think you should do some other runs.

    I think there are Veyrons and Enzos which would be very terrified of meeting your stock Turbo .

    Re: Ruf Turbo innacurate vbox results??? please he

    a 7.5s 100-200kph run on a stock car is exceptional, but I don't think it is representative of what most stock turbos will accelerate

    There's a mild negative gradient, so I think most stock TTs can accelerate like that.

    I am not sure the mild gradient is responsible for the over one second difference from stock numbers. this is the performance of a chipped TT. I am starting to think that maybe it was a waste of money buying the performance box, since the numbers are all over the place

    The gradient is close to 2*. Couple this with a sufficient tail wind and the 7,5 is quite possibly the correct result.

    Re: Ruf Turbo innacurate vbox results??? please he

    The 7,5s are pretty good numbers for a stock car. I think the gradient was usefull indeed. The temp was around 0 Celsius, what is also good for a turbo car.

    I would love to meet an other 997TT to see if there are really differences between stock cars, but they are hard to find on the Autobahn

    Car is a tiptronic, one passenger, half tank and some 30kg luggage.

    I don't think that the acceleration performance of stock 997TT does vary significantly... I think that different results are very likely the outcome of different test environments. Nothing more and nothing less.

    Porsche turbo engines have a very, very limited production tolerance. hp figures do not vary significantly

    that's not true - i have the fastest stock 997TT on earth (just kidding)

    I don't know what the reasons for the differences are, best would be, as RC always saying, to meet on the Autobahn or a track and check out the 1:1 performance, after that all BS has gone.

    I think this would be really interesting and all speculations about plenum, GPS, mufflers,dynos,... would have an end -> Rennteam meeting

    Re: Ruf Turbo innacurate vbox results??? please he

    Guys, The performance box is just a waste on money!!!!! I smoked a GT2 by a car length and slowly walking away!!! RC tested the Ruf TUrbo and almost was neck to neck with the GT2 with a slight advantage for the Turbo, i smoked a 620hp m6 that runs beside the GT2's tail all day long!! i just tryed yesterday with a stock tt with a full tank of gas and gave him 3 cars lengths in 700 meters and he had the advantage cuz he slammed the gas before me!! im going to test with a 997tt with the evo 610 package these days and will give u the results!!! and a video if the owner agrees!!
