Rule change submissions close 1 March 2016 - be in to win.

[jasonu]

are they really that useless? .

Not so much useless, rather they just don't give a fuck about Buckets. (except of course for the huge amounts of cash the class generates...)

[TZ350]

Has anyone got the original ruling and submission?

No, it did not come from us.

Would love to see more photos of them and the engine setup.

Plenty of photos here https://www.facebook.com/UoAfsae/photos_stream even a few of the car. A google image search on Formula SAE throws up some interesting pics as well https://www.google.co.nz/search?q=fo...sBIcQ_AUIBigB#

OK, let's get one thing clear. Presuming he is capable of learning different bikes, Nathaniel would beat us all on a hot FXR or the GP125 Av made everyone look a bit average on.

Does anyone still have a problem with that?

Ok continue, but stop making out a peaky mid 20s 80 in an NF4 is some sort of magic combination.

As evidenced in the photos they have a few of the old cars sitting in the lobby here. I am sure if you sent them a message or something someone would show off the cars to you.

You obviously have a problem with it cos you keep bringing it up...

Great pictures, thanks Pumba.

No, I've accepted it. On that bike I'd beat at least 1/2 the field, but I'd want to have my bike running well (which it rarely did,) before I'd take on say Kel on his 125 or Regan on his 150 and expect to be racing.

I don't think I'd keep up on the Derbi.

I will bring the old fxr up and we will get him out on it for a ride then look at some lap times then we will all no. I do not think he will go any where near as fast on it.

OK that's one for the magic bike theory.

Some napkin math I did the other day estimating the amount of air required to cool an air cooled engine making 40hp is over 1.5m³/s. Like...a lot. So yes I would say that that limit comes first currently.

I am not sure what 1.5m3/s looks like and even with ducting if a motorcycle moving at an average of 60km/hr is able to pass that much air over the engine.

HOWEVER - Just because cooling limit comes before intake air limit, it does not mean that the rule has no effect the class. Careful consideration of restrictor design, carb selection, tuning and engineering outside of the normal scope of two stroke building is required to make it all 'click'. This requirement takes development time away from other aspects of the engine, which helps to keep development speed in line with other engine configurations. As such I think the rule is working, and should only be modified for clarity and ability to be applied to EFI.

Not everyone's cup of tea I know, but for me its that affordable engineering challenge that makes Buckets so much fun.

But it is true.

I have seen Nathaniel an Gavin do a bike swap at mt Wellington , I didn't get lap times but Gavin was similar speed on Nathaniel's bike after riding it all day to his fxr an Nathaniel looked pretty fast on the fxr after just doing 15 or so laps at the end of the day on it . Would still be interesting to see at tokoroa I'm sure he would be happy to have a go on your bike if you asked.

But it is true.

if his bike and him self is the same weight as me and bike i would beat him in a 10 lap race every time

I think it would be interesting as my fxr is so ruff to ride to the 2t there is no doubt in my mind he is a good rider. him and his bike are the complete package in my mind.
