DYNO Numbers for Baggers???
#4961
#4962
Had my bike dyno'd last week I have a Thundermax, level B heads, TW-8-6 cams, SE extreme AC, Rinehart true duals, 107 10.5 pistons, only got 92HP, with 111tq. The Thundermax tech was there and put my bike on his computer for over an hour, changing different settings, when it was all done he showed me graphs where my issue with my bike was starving for air. Dyno guy also stated my bike had a stock Throttle body, with my setup, my heads were starving for air, then he explained that the stock throttlebody measured only get 31MM of air through a 50MM Throttlebody, suggested a HPI which gets 58-55MM to each head, he measured a stock Throttlbody, and he was right, air is king. Next week I'm going to purchase a HPI Throttlebody, and put it in. Folks that I know who have had top end work done stated this is a must.
The Thundermax Tech stated, my injectors were marginal according to the graphs.

When I had my FM 2007 EGC 107" build done with Level B heads, Fuel Moto suggested going with the SE 50MM with 49MM injectors, which they found did a good job matched for the 107/heads build. Rinehart true duals should provide plenty of flow. You'll realize another 10/10 or more I'll bet.

I'd like to see the graph before making the assumption on the tune. There's a good chance it's in the tune, but it could be timing off, sumping or a number of things.

Good point but I was assuming ccp test was already done to verify when the engine was assembled.

My bike was on the dyno for at least 45 minutes, then the TMax tech spent another hour and a half adjusting things, and uploaded the newest firmwares.
One thing they told me was to take them damn SE spark plugs and replaced them with stock ones, they said those cause RF interference, what ever that is.
I still haven't purchased my HPI, going to do that purchase this coming Friday.

I'm looking for the graph, I was so disappointed in the number after my tune I don't know what I did with it.

Also seems even those guy's can't tune one of there products either. It's all in the tune if it's not sumping.

Don't get me wrong here because I'm not a fan at all on the T'Max's so I'm not supporting them but ease over on HTT forum and mention SE Plugs or other's that are similar and you will get the same response as the T'Max did.
