Not sure I would want to pay the difference between kits 1 and 6 to take a measly 2.6 seconds off my 0-300 time. That's €66K not well spent!

Those numbers smell funny.

MOD500

Heard back from Herr. Schnarr, who says the issue of Sport Auto out on the 11th April will have 0 - 300 km / h data in there, and in the mean time to look at the numbers from this 544PS car test:

Good pickup Jussi. My calcs were erroneously based on 2wd losses. Your #'s make more sense because the long G's really start to flatten up there

eclou

Some other #'s from the Mile -

996GT2 700 evo kit - 176 mph
997TT evo shop car - 190.010 mph (my guess was this car was extensively tweaked - they were running PIWIS diagnostics on it all day)
Dinan E60M5 stage II (intake, throttle bodies, exhaust, tune) - 164 mph

Here is another plot from the next run. The top speed actually dropped 1mph but I shifted at about 7k rpms instead of 6500-7600 in the 1st run. Was able to get 130.59mph at 1320 feet:

The wind got progressively stronger thru the day, and was enough to knock one motorcycle rider down! Fortunately he survived with only road rash and some minor fracture IIRC. This next run above was actually filmed by a helicopter. When I get that video I'll post it as well.

My non-sport car with Protomotive upgraded vtg's , exhaust , intercoolers and ecu with 2 passengers and pump gas ran

0-100 3.2sec
100-200 7sec
200-300 18sec

0-300 28sec

My friend in Greece has same mods plus headers ( his cas has SC ) ran

0-100 3.1sec
100-200 6.3-6.4sec

I posted this on one of your 997tt threads - but it is probably more pertinent here...
Some more data:
Apparatently they tested the Cargraphic/RST 598PS 997tt and it did 0-300kph in 26s with the 645PS version doing 23s (this is one with the $$$$$ intercoolers).

Eclou I note on another forum that AWE will be pricing your kit near the Ruf 550 kit - is that around $15K ?

I know its always "we need more data" but with that head wind and the heat/humidity we/I may be underrating your car's real output. Do you have any suitable "track" straights where you can wind it up again - even a squirt to 160mph will tell us plenty (since you have already proven that the motor can pull sustained Gs to 300 !)

Stummel

That could have been me

eclou

23s to 300 is just insane! I don't think the wind could make that much difference. The CG/RST car is immensely strong. I may not have a chance to get data to 160mph responsibly, but can safely get some 130mph data on the next 60-130 competition (I might have to contact a divorce attorney if my wife found me sneaking out at 4am to get a cool blast on the open freeway....)

Felix

She should be pleased that's all you're sneaking out for...

TB993tt

One of the beauties of these power levels is that the blast 100-250 takes less than half a mile + braking distance - surely you have such a stretch nearbye ?

Geeez if I was that way inclined I could easily do this two or three times on my 20 mile journey to/from work (and I work in a major city), "if" I was that way inclined

DAMN!!!

So modded vtg's on CG698 kit and Gerrett turbos on CG645 kit?

I mean Protomotive 997 GT30's still has stock engine , cams..etc and made 830hp

TB993tt

Both kits have the same modded VTGs - RS claim they are "spezial" from their racing relationship with KKK - but then all the other tuners claim something similar
Doesn't this thread and in particular the discussion of the acceleration of Eclou's AWE 700hp make you want to know the actual on road acceleration of Protomotive's 830hp kit rather than the "hp" numbers which (when coming from 9s chassis dyno run) means little in relation to engine dyno "Porsche" standard hp ?

If it really has 830 equivalent hp then 0-300kph will be in what, 17s ?

RS Tuning apparently limit the torque on the first few kits to sub 820NM and for kits with more torque than this they build engines with Carrillo rods since the stock rods will bend over these levels. The Protomotive 830hp you quote will have 950NM (@ peak power ~6200rpm) so maybe it has magic rods ( or maybe the torque is measured differently for a different audience )?

I think your timing of 0-300kph in 28 seconds is outstanding. I believe you have sent me the data of your DBOX once, if so, I can tell you what your car is putting in real life.

As to Protomotive's 830 bhp, I think there is no heroism in building an engine with those power levels on stock internals, that has now been proven so many times with all those 996TTs putting mad chassis dyno numbers and insane boost levels and then end up disappearing from the scenery.

Knowing Todd very well, I know that he does not approve or encourage such setups but he does have to listen to what his customers want or he will loose them to the tuner next door, and unfortunately for him he does not have racing teams backing him up financially. At least he warns them, and also he has full control of his tuning as he does it himself, which helps.

More importantly, those 830hp numbers are simply incorrect, just like almost everyone elses that we see lately everywhere, it is just getting worse with time and out of control, the numbers are insane and completely irrelevant, especially when it comes to torque curves and peak torque numbers thrown out there. Everyone talks about efficiency of engines blablabla, intake this and that, better fueling, state of the art intercoolers for $2-3k , special injectors and what have you, yet we have yet to see one of these zillion hp cars going below 20 seconds in a 0-300kph run, which is what this thread is about. The best I have seen so far around these forums on a 996TT/997TT has been 27-28 seconds I believe.

Funny enough I did today the calculations for Eddie Bello's recent run, where he clocked 226mph in one mile, the 0-300 kph must have been around 15-16 seconds, I estimate his HP to be around 750FWHP, with his aerodynamics and weight (IMO opinion around 2500lbs), sounds impossible, but trust me it is not far off. On a lightened 3000 lbs 996TT, the same run would have needed another 200HP....All of this is theoretical, but will not be too far off the reality.

Let us not forget the GTR 750 that did it in 21.3 seconds, and it was not a prototype running 2500 lbs and special one off custom made stuff, just a car that the magazine took and tested Independently. Some others like 9FF did 0-300kph in 21.2 with 780HP.

I for one would love to see one of these cars going below 20seconds, but so far I have not seen anything close to it.

Freak997tt

All respect for CG/RS tuning and Protomotive..They r the best in the world IMO!!

It is possible that some of the discrepancies in calcs vs performance may be simply due to factoring in overdrive gearing. In the 0-300 the last pull (in my car at least) is in 6th which is overdriven so the engine has to put out say 1.2(x) HP and TQ at the crank to achieve the required (x) HP at the wheels. Assuming a car needs 575hp to hit the 300kph in 5280ft with a given drag and time then the car has to achieve ~690hp at the crank before the power gets reduced by 0.79 OD gearing in 6th.
