Mike, Its hard to see- easier if you print it but there are 2 runs on that dyno sheet, I think its before and after... The after has the torque up near 100 at 2500 rpm. But there doesnt seem to be alot of increase in total numbers...

The increase is in TQ and where it comes in and leaves. You must remember you STILL HAVE STOCK HEADS AND PISTONS!!!!! The biggest factor is in the driveability. The numbers I saw were very good numbers with TQ showing up in full steam at 3200. Also the TQ numbers I saw were higher than 100. Hell my SEEG had 104.4 in bad air at Myrtle last fall.

 Your missing potential torque from idle to 4000rpm!

 Your peak number are very good as is for the package your currently running. But in a race through the gears from a dead stop identical bikes but one has a 575 & Fat Cat vs your current configuration guess who wins everytime?

 The who has the stronger torque curve! The race is long over before you hit your peaks..........JMHO

Brian you are correct. TQ is what gets you moving HP takes over way down the line. The bike with the higher TQ numbers that come in early will most likely be the winner.

Hell if you look at Hubbards dyno most people would think for a built 120 it didn't do what they would expext!!! Sure the HP is only in the 120's but the real eye opener is the TQ number that is in the high 130's. You will not touch that heavy bagger. I am looking for some numbers in the 120's  (TQ and HP) when Punkin is finished. I may have higher HP numbers than Hubbard. I can tell you my TQ number will be much lower hence getting my doors blown off. You must look at your TQ curve, where it comes in how high it goes and where it leaves.

Now you guys that think that the 575 cam is not all that. I can take a stock 103 with the 575, air cleaner and pipes that is tuned and you are not going to keep up.

Mike,

This was done on a dyno jet 250i with a Race Tuner.   Zippers 575 chain drive cam, with D&D's with stock baffle, HD SE A/C and Zippers element, and Race Tuner only mods done to this bike with.  Remember this is not a gear drive cam and it was run in SAE mode here in Florida.   Under STD we gained about 3 hp / 3 tq and we left the air cleaner on with its cover as well, and we had 40 lbs of pressure in the rear tire.  

I would expect the Thundermax to get better numbers it has over twice the tunability points to ensure a better running motor.  If Dan wants he can send down a map in the tuner and ask Jim to run it again.   I am quite sure it will pick up a few ponies.
