No, but have you considered a tour of the US in an F40? That way you could stop by for a few dyno runs. Steve
Tim, I have been looking for an F40 through Ferrari of Seattle for 2 years and 3 months now. I have had many, many close calls but so far...
Rick, phenomenal numbers! Congrats! I can't imagine how much work you had to go through. Any chance of seeing the air/fuel graphs? Also,...
Rick, Thanks for all the info. Believe it or not, I am still looking for an F40! FoS has not found one that they feel good about yet. My...
Rick, I have a few more questions if you don't mind: 1) What kind of boost did you have to run to get those numbers? 2) What did the A/F...
Great numbers! Congrats! Are you still planning on a Silver State type of race for the car? Steve
Congrats on the purchase! Reading your post makes me anxious to get one. Oh well, I guess I will continue to wait until the right one comes...
Sounds good. We'll keep in touch. (Now if FoS can only find me an F40....) Steve
I am working with both Tino and Mike at FoS. They haven't mentioned that car but I will ask them about it. BTW, when I finally do get one I am...
Well I don't feel so bad then. I have been seriously looking for an F40 for about 3 months now and have come up empty handed. The difference...
Gary, IMO your A/F is too rich in the upper RPM ranges. On my DynoJet the A/F ratios that produce the best numbers are right around 13.5:1 to...
I have a DynoJet 248 and have never seen the type of problem you are describing. I do know that obtaining the RPM signal can be a pain. However,...
It is interesting reading what everyone has to say about rwhp vs. flywheel horsepower. Since I have a DynoJet I can tell you that making any kind...
What is even better are the numbers from the 1192 rwhp run: 1 - 1383 3 - 1410 5 - 1371 7 - 1408 2 - 1372 4 - 1453 6 - 1427 8 - 1479...
The leaning out above 7K is kind of an anomaly. Every once in a while I will see this. It has something to do with when I let off the gas and push...
I have EGT's on every cylinder and monitor them after every run. I use the Racepak data acquisition system. As an example, these are the...
I use 92 octane pump gas from my local Union 76 dealer. The leaning out above 7K is kind of an anomaly. Every once in a while I will see this....
Here is a graph of one of my runs: [ATTACH]
Mitch, you are of course correct about using the gear closest to 1:1. DynoJet also has the ability to measure and graph "Negative horsepower"....
4sfed4, two of my cars that I dyno regularly make 607 rwhp and 1192 rwhp so you can see why I didn't want to be too disappointed with the 360....
