Todd,

The car was finished and I picked it up last Thursday. I drove it down to the Concorso Italiano on Friday. I don't want to spoil the surprise as to the final two modifications. They worked very well, there may even be a couple dozen ponies that can be rounded up yet. The last two mods added sixty-eight hp, they have the potential of ninty. The good thing is the power was picked up from 4400 rpm's through redline. A soon as your Stage V is ready, let me know. Dave Colman is ready to arrange the track, strip and dyno. Just waiting for you to say your beast is ready. The last time we talked you said you needed to the last week of September to properly ready your Stage V car. When you tell me what day it will be ready by then Dave Colman will arrange a firm date.

 

Chad, Sounds good. I will let you know the status and the time line for the stage V car. Am I to assume that your car put down 683 RWHP??????

 

You are giving me the advantage of a couple of rwhp. Without liquid CO2 or N2O we are at 614 rwhp. With liquid CO2 and N20 it is 681+. Not sure what it is with just the liquid CO2 activated. The liquid CO2 does make a .3 second difference in quarter mile times.

 

Slightly steering back to the topic, our R turbo will be equal with a Stage IV till about 150mph whereapon the RUF will pull away. Also Alois RUF's car (MN RT 350) has done 35,000 miles in just over a year most of those at speeds above 300km/h and with heavy footed journos driving, the car is bullet proof, and to my recollection not a single thing has broken yet

RUF's hp figures are always conservative, we bought one from them looking for the 542bhp/580-tq engine, but it aint that

Adam,

Can you expound further on your comments? How do you come to the determination that your R Turbo will be equal to a Stage IV until 150mph? Have you had your R Turbo around a Stave IV equipped car?

I ask because I am wanting to do one of these two options, but can't make up my mind.

 

I assume that you are spraying CO2 on the outside of intercooler. I did not think that spraying the IC's made a huge difference. I tried it a while back and only noticed a few HP gain. Love to see those 614 RWHP and 681RWHP dyno graphs. Please post them

 

Todd,

We are off topic on this thread. Go to cjv/ s car go, new thread. We don't need to be hijacking this fine thread.

 

Michael, I posted a video of us doing 0-190mph in the rain, and a nice chap on the board was kind enough to compare the results he got when he timed his stage IV in good conditions, what he found was i think we were down on him to 60 and 125 by half a second and then above that we regained the gap, i cant remember all the details it should be on the board somehwere.

Im wondering how much RUF aerodynamics would come into play at speeds 150+ compared to a stock body TT with Stage IV.

We should have Detailer (ruf bumper and wing + Stage IV) go up against a RUF car and see what happens!

 

I think aero dynamics help tremendously, for instance i remember mr RUF explaining to me that when they were first maxing our the original ctr they lost about 2-3mph in top speed when they used normal 911 wing mirrors, that is why the ctr has small racing mirrors, and so too does ours, i dont know how much they help but i guess every little helps.

I would love to see a graph on how the stage four looks horsepower and torque wise, all very interesting stuff

Aerodynamics plays more than you can imagine. When I was building Monster years ago the goal was 220MPH in the 79 930 chassis. We found that the old style mirror to the new style 993 mirrors caused 2.8MPH loss per side. The rain gutters cause the dirty air and friction above the roof line and a total of 7MPH was gained after shaving them. All which makes a big difference. Also FWIW a narrow bodied 996 will be faster top end than the turbo's wid **** due to drag. YellowBird is a good example of this. The drag of our cars is far more than a narrow body. Some of the worlds fastest cars have been slim line RUFs..

Here is the IV on my car...if you need more let me know. I have a ton on file

 

That's hella torque Stephen

 

Gets the job done

 

Thank you stephen, thats very good,

did you get to 220mph?

Adam,

I am trying to understand your comments, :

"our R turbo will be equal with a Stage IV till about 150mph"

then you follow up with:

"what he found was i think we were down on him to 60 and 125 by half a second and then above that we regained the gap"

So, is the R Turbo equal to 125 or is it behind, by a half second, until 125? I am not trying to bust your chops, just trying to get an understand of what each offers. From a numbers perspective the RUF package is far behind the EVO, but from all the comments from people the numbers only tell half the story.
