Awesome! Glad to see that you plan to get the car out on the track.

Even if it's not possible to put down all 1000 or 2000 horsepower,
you should be able to get yourself a very good time and test some
aspects of the system. Mainly being able to get a launch, and
progressively add nitrous without losing traction. If you can
get the launch working well, and can get it down the quarter mile,
it should be just a matter of keeping on adding more nitrous
for your top speed run. But this is a great way to test it...

Make a run then later update with another 100hp then make another run etc.
Do you have any setup that will ad more nitrous after the car is further out off the line?
Adrians car runs 13.39 as listed on dragtimes.com
http://www.dragtimes.com/Porsche-928-Timeslip-8727.html
as a stock GTS should be a 13.7 1/4 mile car depending on driver,driver weight etc.
Anyone else who has run their car in the 1/8th or 1/4 if you get a chance list it with the other 928's on dragtimes.com
http://www.dragtimes.com/compare2.ph...ame=Compare%21
I think there may be a couple of 928's that are supercharged in the 11's for 1/4mile and that is most likely with some traction problems.

Hi

There are some weird things on that page...you linked...

It says 5.0 ltr 1990 with GTS cams and a supercharger ??

The track is wrong as well as it was not done in the US but at SantaPod in the UK ?

I have never seen an 11 second time slip for any 928....and tend to doubt that time as a 10 is Veyron country....

I will ask Adrian about the link and come back to you on it....

All the best Brett

Hi

If Adrians time is a 13.39 then I need just over 1 second to beat it and take the UK record as I have run a 14.4 with no Nitrous with the help of the LSD, which made a huge difference...

All the best Brett

So you basically have a 125 shot per cylinder?

Hi Andrew

No, at the moment I am testing and increasing VERY slowly....

Eventually I "COULD" have the whole 2000 hp the REVO system is capable of, but I seriously doubt I will ever need that much for my aims...

The system is set to give me a maximum of 700 hp progressively at the moment through the special REVO settings in the Maxx controller,while testing etc....then another 700 hp on top IF I decide to activate it, then the final 600...

But not yet lol...

All the best Brett

I think it was Tim Murphy who ran 11.7 in the 1/4 mile, or one of his SC'd cars. It may have been a G-tech time, but still good enough, and the hp numbers would certainly warrant the 1/4 time.

Thats what I thought was on another thread in the high 11's on Tims car and someone else had another 928 that was in the area of mid 11's not sure where that post is yet.
The Gtech were high 11's
http://www.murf928.com/forum/viewtopic.php?f=7&t=14
Which is about right as a 7.7 in the 1/8th
7.7/.65=11.85 area.
I use /.65 to convert 1/8 to 1/4mile which usually is close.

Here is another benchmark to shoot for:

http://jalopnik.com/5524786/heffner-...ng-mile-record

Twin Turbo Ford GT with 1,900hp hits 266.93mph in the standing mile

The previous record holder was another Ford GT with "only" 1,400hp that hit 252mph

That aerodynamics for yea, assuming the HP claims are somewhat accurate it took 500hp to go another 15mph.
The Ford GT is also slipperier than an "S" bodied 928, superior transmission and a hell of a lot more traction.

Both GT's easily beat the Bugatti Veyron, I'm sure the weight difference helped a lot since a stock GT weighs about 500lbs less than a Veyron.

Remember HP is nice, but it's torque you want if you're trying to reach max speed in a given (short) distance.

Wow, 41 psi of boost surprised the engine can take it!

Good luck with your project Brett, can't wait to see some video. I guess your car is a bit of a test mule to see how strong the factory engine internals are.

so if I understand this correctly, there is no 928 that runs 10s in the 1/4 mile???
if so then this could be one hell of a good challenge

It all depends on where you define the torque. Defining it as torque at the wheels you are correct (don't think Mark would even argue with that) If you are specifing at the crank... well good luck.

Hi

Thats precisely what mine is aiming for.... although my "AIM" is just to be the "Fastest Porsche"...

Hi

Correct, absolutely and definitely NO 928 has ever run a 10 , not even a 10.99....

Although I will run the 1/4 once this year, it will only be to hopefully take the UK record for any 928..and a low 13 will do that, as mine is designed for top speed , it will never run a 10....unless I achieve my top speed aims and then decide to alter a lot of stuff which is doubtful as its my daily driver as well....

All the best Brett

Any ideas on the torque limits of the TT or the half shafts? Half shafts are the first to go I think, thats how it was for a local guy with a Chevy swap.
