But then your simulation simply doesn't converge, like RenM said? Did you use enough iteration steps (turbo sims need way more than NA sims)? Or see below...
Why should it be not...

Indeed! I never worked on a turbocharged FSAE engine, but on Group N / R4 rally engines now... Which is basically FSAE x 3: 33 / 34 mm restrictor, turbo, thottle after turbo, 2l engine. Okay, plus...
Simple: You don't input that parameter.
As you said, with your "balanced" option, you can give the software an initial turbo speed. The software will then calculate the "actual" turbo speed for the...
12.5 for my old team's last dry sump, without modifying anything of the engine crankcase ;)
But then again, you will get some power back (crankcase vacuuming)...
Jay is of course correct with...
No problem, do that! :)
This is a possibility certainly (and a certain team I happen to know very good did it just like that in the past), but keep the templates in mind... Depending on how long...
I do understand that partly... When I joined my team in 2007, we just switched to the PC37 engine. The same you are using. And yes, we too found out that the oilpan is extremely tall, and yes, there...
Composites? I did only mention them because they are quite obviously visible in the picture, and I know Z's opinion about the use of them. :)
Difficulty of an elegant solution for sitting the mounts...
Think 3D and install the shocks longitudinally, directed to the back, with the pullrod design? CoG low down and nearer to the middle of the vehicle, and shocks not interfering with the template......
Adding to what Jay said:
2. I don't really know how Ricardo Wave does it, but the simulations I know and work with will calculate turbo speed itself (with the help of all the data Jay mentions,...
I agree with RenM that cam timing and valve overlap are probably the most important things to get right.
But on the other hand (and if you get the timing right), the CBR 600RR WILL in fact benefit...
I agree. IC1.6.1/1.7.1 + 1.7.3 (Why should the use of recirculation valves be prohibited?! I honestly cannot find any reasonable motivation for that. Open blow off valves, okay, to prevent any chance...
Jay already answered to this, and I am thinking the same: No, IMHO it won't work, because of the reasons Jay mentioned.
You would basically need two different sized compressors on the same shaft,...
We used sponsor supplied stickers in my first season in my team, 2007/2008. The judges in the style event which was part of FSG back then really didn't like it. Some time after that, we bought a...
Don't worry, I think we understand what you want to say :)
Well... I don't really think that the shape of the oil pan is a perfect criteria for choosing an engine O_O What about the big picture?...
Yes. If you drive slow enough.
Joking aside, it would be nice to hear why you think that the CBR600 F engine (by the way, which one? F4i?) is "the best". Or if you you want to use a completely...
We did the same, actually ;)
Great movie, and I will second all the comments above about Brühl's acting - fantastic.
Only the "how to make the car 2.3 s faster in one night"-scene... Oh well,...
Sorry that my first answer was a bit short, but it seems you are on the right track now :)
By the way, if you are interested, there are some actual dyno measurements of different cars on the same...

Hm. At all engine speeds?
Ditto.
And the navigation is a pain...
Turbocompounding is also allowed by the rules...
Smaller in diameter, but wider (in case of a multi-cylinder engine), as you mentioned below.
Keep in mind that conrod length affects the engine's secondary balance. So, with shorter stroke -->...
Thanks. And yes, it certainly affects peak power http://fsae.com/groupee_common/emoticons/icon_smile.gif
Well, you wouldn't get very high performance out of a long stroke engine at high rpm...
Diforesi,
Explain to me please how a long stroke engine produces more torque?
Pat </div></BLOCKQUOTE>
I think he is talking about more torque in the lower rpm range. Which can be true:

Hi Phil,
I agree with everything above. You can also contact us at http://highspeed-karlsruhe.de/index.php?id=273 and talk to our suspension guys, or simply come and visit us - we are just 30 km...
We have the deluxe version http://fsae.com/groupee_common/emoticons/icon_smile.gif

But access to the big machines: Only supervised. We are lucky to have some...
