JJ - I think upgraded selectors were/are billet alloy-- happy to be corrected. Available in the US thru PowerhausII -- I think that is correct. Try Albins and it will direct you there.

 

Jean,
Can you put a normal 993TT or 996TT into the graph also? It would give a little more perspective on how really quick the cars are.

 

Jean, thanks so much for posting the distance data. This is where the real surprise is. Here's the "virtual race" results after racing for a full 6 seconds (which is pretty long) with both cars starting even at 60 MPH. There's 5 car lengths between the slowest car (115 MPH) and fastest car (130 MPH), assuming a car length is about 14 feet.

 

Looks like there is a lot of turbo lag with this setup. Below 4000 rpms not much power? How is it to drive?

 

[QUOTE=Jean]
I had some fun today with the data, and following Bill's request (after all he started the thread ) I did the attached graph which shows how would the cars have compared had they been street racing...i.e. who would be ahead and by how much.
--------------------
hello Jean
can we have the same for 100-200 km/h and in meters please ;-)
also put the 993TT and the 996 TT stock in it.

I leave for HHM today

I will try to gather the data and post it.

Konstantin, I have it in meters already only way for me to understand distances! Will post soon.
Enjoy it and good luck!
Cheers

 

My car drives much like stock when not on boost, but as you can see it stays in boost when shifting through the gears. First gear goes away when it gets into boost (tires spin) second gear hooks up with new 315/30-18 Pilot sport cups. I think the Quaife dif keeps the car straight and hooked up with 50/50 to the rear wheels. I would like to add I enjoy the kick in the *** the big turbo gives when it hits full boost. One thing that needs to be done to this set up is a second waste gate. Now the car has to be set at a lower boost because it continues to creep after the waste gate opens it also does not have full boost when the car can really use it. When I get that fixed and the outside temp in Florida is lower I would like to try the run again. I would also like to get Joe Essa to try it with his new build twin turbo 993 reported to be over 1000 rwhp.

 

Kon:

Good luck at Hockenheimring!!

The porsche motorsport shift fork is steel. I put a magnet on it.
Stock piece is aluminum with steel insert.

Can't beat the magnet test! Or maybe it's like dynos and the AX. I am joking- for those that are never sure!

 

Over 1000wbhp!!!!!!!!
**** me!!!!!

The AX22 in "continuous mode" is a reliable measure of acceleration (with a caveat about the "track" being level) - not to be spoken in the same sentence as "chassis dynos".
The results it delivers may be quite upsetting - hence the complete radio blackout on the 6bling site from the many who purchased the unit - even Evo Motorsports who apparently have bought an AX22 but continue to prefer chassis dyno numbers to real world results.
I find it amazing just how many people continue to buy "tuner's" wares when there is so much good information available on the net now days

 

I've just completed a day at bedford autodrome and measured my performance with Phelix's DL1 data logger. Best 60-130 along the main straight (standard ecu, big cats) was 11.92

Cornering with road tyres was a little over 1G

 

According to http://www.einszweidrei.de/porsche/993t1995-1.htm (tested in July 95) and http://www.einszweidrei.de/porsche/993t1997-1.htm (tested in June 97) 100-200 kph (62.5-125 mph) should take 12.1 or 10.8 seconds, respectively, in a stock 408 bhp 993tt. 60-130 mph represents a 12% greater change in speed than 100-200 kph so (admittedly crudely) adding 12% to the road test times brings those numbers to 13.6 and 12.1 respectively. Thus 11.92 looks quite strong. Alan, were you able to get the boost sensor to talk to the DL1?

 

TB-- I have never really been interested in 1/4 times etc but the idea of a accurate world-wide measurement such as the AX results is interesting.I will collect info as soon as is possible.I have a couple of interesting engines .I would say that the expert opinions re 1/4 mile terminal speeds also has a degree of logic ie-- it needs XYZ HP to achieve ABC terminal speed. Your reference to the absence of fact re 6 spd has been noted.I have seen many engines from both US and Europe fail to live up to dyno numbers achieved there and are used to seeing the engines drop HP on the journey overseas!
Your point about good information on the net is also relevent-- but it does require input from diverse group with different experiences which is the fantastic thing about forums like this and the unselfish contributions from people with terrific knowledge and experience.
