Now you make me want to create a new username and wreak havoc. lol.
As for Bills 194, I really shouldnt speak for him, but I will. He did 194.6 Sunday morning with the old AGS tube. I dont know what his runs were before then.

I know a few guys with these cars and they all thought they haulled *** untill they had the problem corrected, then they were surprised at what they had been missing all along. Its not a cheap fix, but then again what is cheap on a Ferarri.
I just had a 30,000 engine out major service done w/belts and everything looked strong. Compression test revealed no valve guide issues. I made it an issue with service to check and see that the car was not having the notorious valve issue. Actually, relatively small numbers of 355s have this problem, but the car has been saddled with a reputation for the problem. Usually the issue appears within the first 20,000 miles. Since I had a full engine out at close to 19,000 the odds are against a valve guide problem. Car has a Tubi exhaust which usually gives a HP bump. I don't know what the closest 1:1 gear ratio is so the DRS guy and I decided to run in 4th. Perhaps that might account for some of the loss if that wasn't the best gear.... I don't know.
Hmmm.... need to find my spec sheet. OK, found that the ratios for 4th and 5th are 1.27:1 and 1.03:1 respectively. Looks like we should've made the run in 5th. Any dyno experts out there that might know how to correct for the ratio difference???On another note, it was interesting (distressing) to see the JCW running soooo rich.
Need to take a look to see if I'm running old software.Glad I didn't bring the M Roadster or I probably would have walked away totally depressed!

The center chart is the two runs, early morning with the old AGS 197.64
and in the afternoon with the new AGS 202.94
You might also notice that there is no HP drop off until it hits the rev limiter at 7200. You and I were discussing that possibility as the SC goes over it's red line.
Here is a look at the last run:

We sure missed you, it would have been fun to see you whip me.

Ha ha ha I hear ya. I had a chance to take th ebikes out and couldnt pass it up. My body is a little sore from it but I am glad I went.
Not those charts, the ones from a couple months back.

I really only know 2 people who have had these cars for any period of time and they both had the valve issues, one was fixed at beverly hills also. And you are right on target with the mileage, they were just under 20K when they had them fixed.
I am curious why it didnt make more power ? Expecially with the pipes, which I have heard make decent power gains!
Lucky you, a Mini AND 355!!! That is one of my all time favorite Ferarri's !!!!!!!!!!
Get an apexi and you can dial out that richness and gain some power.

Dyno Day
Much to my surprise that all the minis that showed up was looking good and ran great and the 355 was a bonus, just the sound from all the motors on the dyno was worth being there and thanks to all. Great meeting people that are pushing the envelope for the rest to learn from.

The only other reason would probably be because it's green... British RACING Green baby. (Notice that the other Green car there had killer numbers, even for an 05).
Just chatted with the guys from DRS and the fact that the car was on 91 octane and not the Ferrari preferred 95 might have a significant impact on the 355's performance. Another issue is the ECU might not be properly set for the Tubi. However, the motor felt very strong and not symptomatic of one with issues. Kris at DRS is confident that the missing ponies can be found. 
OK, I feel a bit better now.
Now if my dealer would get back to me quickly about the software version in my JCW MINI...

Hey, how come the #'s keep changing??? What is this uncorrected stuff...geez
I thought sae was the standard, if we go by uncorrected mine was 215whp +
Look at the chart below it says 201.8???

Anyway, here are the results:

Anyway, here are the results:

I am only putting the raw files into DynoJet's software.
I included the one graph as uncorrected just to see if you were paying attention. The software at DRS seems to be using a non standard Correction.
In my original graphs you will see they are SAE corrected. I don't know where his numbers come from.
Randy Webb says he only specifies uncorrected data. All his numbers are uncorrected.
In the case of these runs the difference between corrected and uncorrected was less than 1 hp.
If you look at the original charts the 202.94 is SAE corrected. The number is a bit larger uncorrected.
Go back and look at the original charts.:smile:

Maybe I'll try putting that in the car and then make another dyno run.
