Gotcha, makes sense now. Thanks Neal!:nod:

The B6 is definitely potent with a shim removed... I am working on the modded version right now !

Dyno of Mod Speed and Mod JL.21????

WOW!!! These numbers for a stock $200-$230 engine are incredible. It's funny that you mention removing a head shim because way back on the B5 thread Ron talked about safely gaining free HP by removing a shim if running Werks 30% fuel. I'd honestly forgotten about it til now. My engines were already flying, can't wait to see them w/o the extra shim!!!

Thanks Neal for sharing the info and risking the backlash you're about to receive from the loyal OS fans.....I also like how you explained removing the shim was to equalize compression ratios for testing, not to give any engine an advantage over another!:nod:

And while your at it, what about the Team Orion Alpha, the engine that just won the Worlds....

Hey Maximo or anyone else. What do you guys prefer to run on the clocked b5?

The dyno is a very interesting tool.... even when I change my inertial flywheels the results change engine to engine...some engines pull the heavy flywheel with no issue, others fall flat on their faces.... Some engines that will not pull the heavy flywheel thrive on the lighter flywheel, and other engines don't seem to be affected...some pull the same results on both flywheel masses.........

compression ratio plays a huge role in how these engines perform, IMO testing is not accurate unless the compression ratios are the same or nearly the same...one company may add an extra shim to aid breakin, another may not..of course the engine with the higher compression will show better results..that is a big issue I always had with the magazine testings, they always ran the engines with 100% stock shimming and on the same tuned pipe....So one engine could show way better then another all because of setup..with my testing I try to optimize each engine as best I can in stock configuration..i set the compression ratio and find the most suited tuned pipe...many offroad engines come from factory with the head shimming very conservative, which can really hurt the power output an skew the results to make the engine look weaker then it really is.....

I am not too worried about backlash...I have nothing to hide and will always try to show the show the results of my testing as accurately and honestly as I can......

never tested an Orion !

here is stock Speed vs mod Speed vs Mod JL

oops

Thanks Neal. Those are some good looking numbers over the JL. My Choice has just been made. :ha::p

Thanks Neal for posting the B6 chart. I guess this explains why we felt we had more power when we were at the Worlds than any of the other engines out there lol! Looking at the chart it is interesting to see that irrelevant of which of our pipe design is run on our B6 we are still making more maximum HP and between 2-11% more torque than the new Speed engine, especially when you factor in the considerable price difference between the two if you take their realistic US selling price. Not to turn this into a marketing thing but can anyone say 2 for the price of 1 with some change left over too lol.

Looking at the charts I think that a bit of the drop off especially on the tail end at higher RPM's with our engine is due to the use of a steel bearing versus ceramic. Switching to a ceramic bearing in the B6 should provide a noticeable reduction in friction which will probably increase the overall max HP and Torque numbers further as well as increase/extend them on the back and of the curve.

It's also interesting to see that the graph with the 2057 pipe set is almost a perfect parabolic arch! It's nearly perfectly smooth which I think is what greatly contributes to the engine being so drivable, smooth and the very linear feel that the B6 gives.

Again interesting information and thank you for posting this for all of us to see.

Ron

I wont lie to you Ron...when I tested the B6 I was shocked to see its numbers on the 2013... I even went back and retested a few other engines just to make sure something wasn't fishy with the dyno...Thats why it took me a while to post the results.... So far the B6 2013 with shim removed has the posted the highest torque numbers of any stock .21 I have tested to date..including the B5 which really shocked me.....I tested that B6 many times and its consistently pulling those numbers........ Just wait till you guys see the dyno of the mod B6 !!!

Are we going to Poop Neal?!?!?!?!?!

LMFAO:lol:
