SR-Racing & PP-Performance F10 M5

[GhanemMBN]

cidair: FAST! good result. You guys are lucky, weather conditions there are great! But 0.4 difference between PPP M5 and stock in ur weather conditions is like 0.6
We'll try 200-250 to see the difference. Good Luck with your car btw

[cidair]

I was surprised about the times actually. I think the stock car produces way more than 560hp.

BTW - my friend tested his GT-R P800 0-100 km/h 3.0s and 100-200 km/h 5.2s!

The GTR is a different story, i would NEVER EVER race a gtr in my sls!

Lol, at citing weather differences

Looks to me like your runs were done at night (when cool) and last time I checked Abu D was at sea level. A guy posts German autobahn times on a standard car at higher altitude (= less oxygen) and you say your times are handicapped by weather.

You also are obviously no good at performance cars as you posted an impossible time for a RWD M5, but now can't explain why......any fool that knows anything about cars would have figured out 2.5 seconds is a BS time.

How are your gold plated water jackets doing?

How's your F30 bro? hahaha
AbuDhabi= Humidity, all educated people know the affects of humidity on a car

Average humidity for May is 55% in Abu Dhabi (according to this article: http://en.wikipedia.org/wiki/Abu_Dhabi).

Using this calculator:
http://wahiduddin.net/calc/calc_hp.htm

A humidity of 55% and 30deg C reduces engine power to a relative HP level of 99,2%.

In effect loosing 0,8% engine power compared to 35-40% humidity.

And the weather forecast for Abu Dhabi has a humidity of low 30% for the next few days. Using 35% gives a relative HP level of 100,3%

If you compare that with a stretch of the Autobahn that is at 250m elevation the same calculator gives a relative HP level of 102% at 10deg C and 40% humidity.

The increase in relative power from 99,2 to 102% represents a 3% difference. Even though not correct to just assume that a 3% HP difference results in 3% difference in acceleration times. Regardless of this let's see what 3% represents on your stated times (since you made the claims about weather differences in the first place).

3% of 6,7 = 0,2

6,7-0,2= 6,5sec

So, a M5 at a altitude of 250m and 10deg C needs to do 100-200km/h in 6,5 sec to compare with the same car in Abu Dhabi at sea level 55% humidity and 30deg C.

Mbitious did 100-200 in 6,5 sec on a wet Autobahn and MHR has done a 6,3sec run in the dry...

So, unless you can provide exact temperature and humidity data as of when the timing was done, there is no way to know the real difference the weather represents.

Is that your attempt at an insult?

Adu Dhabi humidity today 8th May 2013 - 40% Wow I'm surprised you can even start the engine in that

Don't even try, you lost him at A...

Stop trying to lash out at the people questioning your false claims, unprofessional business ethics and arrogance. It only confirms their questions.

High levels of humidity displace oxygen in the air and *reduce* the themodynamic potential of the air. Of the total air pressure, any humidity will consume a certain vapor pressure, reducing what is left for the partial pressure of oxygen. The effect is *very* significant at high temperatures and can "cost" quite a bit of horsepower. Cold at night so not your situation

Now, that said, some engines can respond well to certain humidity levels. But that is because water vapor helps resist detonation allowing, perhaps, for more advanced timing or boost.

For an engine optimized for certain environmental conditions, adding humidity to the air will effect horsepower. So you can improve your cars performance with said SECRETS/ running the car when its cold and adjusting timing fueling boost.... You Know a tune for high humidity!!LOL

That does not explain any of the communities questions anyway... Its just a lame excuse to justify that your tune is not impressing you.

The weather here changes so fast, yesterday at 12:00 it was 42^C, 2 hours later it was raining!
Now i took a pic of the temperature, two hours ago it was 43^C

Yeah the weather here has always been the exact same since captain james cook came to Hawaii!! No humidity in the middle of the pacific.

Why are you quoting temps if the humidity is your "problem"....

My cars faster!
did a 1.2s 0-60 mph but I forgot to hit record

Did you guys hook up the flux capacitor?

Renntech is based in South Florida and I've never heard them make excuses about Humidity. LOL.

Impressive results by PPP & MHR
This car sure has potential !! Did you change your tires? If yes what did you use?
