thanks for your help guys. I'll do some research on the B5 with the 2013 pipe. as suggested.

I just broke my B6 in and i was curious if we are suppose to remove any shims to increase performance or we just stick with the stock shimming?

No, It is shimmed out of the box for 30%. If you are running 30%, you don't need to change anything.

ron u got email

thanks, I think I'll give this a try and see how it works out. I'm running a JP-4 pipe would this be a good combo?

The JP-4 is about the only jp pipe i have used that I have ever had any luck with I would use it.....

With colder weather setting in should I use a hot plug or cold?

In all weather conditions you should be able to run with just 2 plugs, the #5 and #6. In colder weather the air is denser so your engines will actually make more power. Rule of thumb though for me is that I always try to run the coldest plug that I can as this retards the ignition allowing me to lean the engine down more, hence more power and run time. A hotter plug will provide you with a more stable idle though and be less sensitive to the state of tune (meaning you can get away with running the needles slightly rich and it will still clear out). I should mention though that the above applies for most normal weather conditions that we experience here on the west coast i.e. 50F to say 110F. I do not have any experience running in 20-30F weather like you guys experience on the east coast in the winter time so if that is what you are asking about I'm going to have to let some of the other guys chip in on that.

I can't speak to the werks motors in 20-30F, but when I ran in freezing conditions in a race, I used the same plug in my OS vspec that I used in normal temperature racing. We were all heat-gunning the motors and idling them with radios off and socks/hoodies on the heads for a good 5 min before our race was up too :)

Once the motor was up to temp, it was business as usual, outside of the fact that they were all nutty fast and needed to be richened up for the denser air!

B6 vs B7
 

Hi there. Has anyone done any testing between the Werks B6 and the B7??

Is the B7 as fast and as strong?

Thanks Ron.

Sure we have. To be specific there is a B7 and a B7-Pro. I think that 2-3 weeks ago you posted some questions about this also and I think that I should have answered your questions about the differences in performance between the engines then. Were you looking for anything specific?

Also on another thread you made some negative comments about you would not recommend the person to buy one of our engines because you can never get a hold of anyone here etc. etc. There is always some one here from 9am-5pm and if we are on the phone helping some one or not in there is VM and you can just leave a message and we will call you back. Did you by chance try that?

No problem, hope that helps a bit!

HAHAHAHAHAHA Sounds like the Dr. should get charged double to me :nod:

bazinga!
