2011 AM to EX Bump List

[Cowboy 6]

A 100 hp engine can only do 55,000 ft-lbs of work per second regardless of the torque.

Since horsepower is not measured but is calculated from measured torque {(torque x rpm) / 5,252 = hp} indeed, the torque is what matters.

...I didn't see the 85HP 225lbs bike in your chart.

225 lb bike + 130 lb rider = 355 lbs, divided by 85 Hp = 4.18 lbs per Hp
225 lb bike + 180 lb rider = 405 lbs, divided by 85 Hp = 4.77 lbs per Hp
225 lb bike + 230 lb rider = 455 lbs, divided by 85 Hp = 5.35 lbs per Hp

At 4.18 lbs per Hp a 130 lb rider on that bike would have a P/W/R capable of winning regional Middleweight races.

At 4.77 lbs per Hp a 180 lb rider on that bike would have a P/W/R capable of easily winning regional Lightweight races.

At 5.35 lbs per Hp a 230 lb rider on that bike would have a P/W/R capable of placing well or possibly winning Lightweight races.

Whatever. No more trophies for me. It was a good run though.

LOL.. Gonna do just fine Mr. Cassell.. I remember when we were working together at JGP, and while on track i was trying to hang AND observe with just take-offs. Nope.. I thought to myself.. shit, im gonna need to get some freshies to ride with this guy.

That is just the way most dynos are designed because it is easier to package a system that measures torque rather than the power.

Why would measuring the torque to calculate the power imply that torque is what matters?

If I made a dyno that measured power directly, then would power be what matters?

I have to say I agree with Ross and I think the turnout for the class speaks volumes.  The Lightweight classes it used to be you could buy an affordable bike in the sub $5000 range and be competitive.  It was a poor man's class.  Now that 1100DS engines are allowed and buells and somehow even $50,000 Bimotas are allowed in the class, in order to be remotely competitive you need to put $3500-$5000 of motor work into that SV and even then you are still far outmotored by stock 1100 ducati engines, let alone the worked ones.  Lightweight used to be pretty popular but now that the price to enter is higher than the middleweight class it ruins the class and causes people to leave and go elsewhere.

I agree. I think I can get around the track decent enough. To have to try and ride to overcome a 30 - 50 horsepower defecit is unrealistic. I gave it hell at the ROC on a 65hp SV and even I gave up after riding the wheels off the thing only to be passed on the straights. The class should be a low entry grass roots class. There are Bimota's that make more horsepower than my CBR600RR. Are you kidding me. WERA has addressed the issue and now it's time for CCS. I guarantee if you fix the rules the class will grow.

[MACOP1104]

Amen.  CCS lightweight rules blow donkey dong.

[HappySV]

As a poor old slow guy on a SV - I have to concur.  I'm still building a newer SV for this season and it'll be an essentially stock engine and running pump.  But without engine work, race gas, weighing less than 130lbs, etc and running against the Buells and Ducs it does make me wonder why I am bothering.  Now running against 250cc GP bikes too?  Seriously?  I have always run CCS exclusively and I plan to run CCS this year, but I am thinking about trying a WERA round this season for this very reason.

Well I'm here until it stops being fun, and if getting smoked on every straight makes it no fun, then I'll be done and have to figure a new way to risk bodily injury and hemmorhage cash while emptying my adrenal gland.  Here's hoping for a fun and competitve 2011 with CCS!

Glad I didn't get bumped.

[Noidly1]

Gee, Professor McLaughlin, that was fun!

Now can you explain why a pound of feathers doesn't fall slower than a pound of lead ?   

 

 

Yeah, don't forget Aerodynamics...

[grasslander]

OK back to questions about AM-EX bumping.  If you are bumped up and accept it becoming a new expert, can you later still request a "once a career" move back down to amateur?
