228 Duration Camshafts On The Engine Dyno

228 Duration Camshafts On The Engine Dyno
We've been working with camshafts with 228 degrees of intake duration here the last few days. We're still testing split duration camshafts, but I thought I'd post you guys a graph comparing the 228R camshaft we've always been selling next to the new TSP 228/228 camshaft using our proprietary lobes. As you can tell the gains aren't huge, but we're working to maximize average power from 2200-6500rpm.... Notice the new 228 lobes have helped to add power pretty much across the board over our older XER based camshaft.
While it's not huge gains, it's still positive gains across the board while not making any changes to the duration. We're testing split duration camshafts using the TSP 228 intake lobe right now, so hopefully we'll have some extra dyno data for you guys soon!
For anyone wanting to jump in the thread & make smart a$$ comments like "wow that looks like a 228 vs a 228 comparions" give it a rest.... This is a comparison of two different lobes in a effort to improve power at a certain duration point.
Enjoy..

Keep in mind guys the first graph is a steady state test where the engine dyno holds the engine at a certain rpm for 5 seconds & averages the results over those 5 seconds. The sweep test is a dyno pull like everyone is use to seeing. The step test often works best for more accurate results because it averages the same rpm tons of times, while in the sweep test the engine is accelerating water all the time.

On the comparison graph, the blue line for the 228R is at zero....the red lines above are torque and horsepower for the new 228 cam (torque starting on top at 2000rpm). Hope that clarifies it and make sit easier to understand!

How about plotting your best 228 cam from this comparison along with your best 224 cam from your previous thread on the same graph. All things should be the same like like sweep, STD corrections of course. I assume you are using the same mule engine.
I think folks might enjoy seeing and discussing that. I believe your software does that fairly easily.
Just a suggestion.

Jon I'd be happy to do that for you. I'll get the 220 on 112, 224 on 112, 228 on 112 with equal advance. Sound good?

seams so damn close in the mid range (working range) from 3000 to 6400 that its not worth a swap. i agree with old stroker test it against some of your other cams. u dont need reasurance from us that your cam on your dyno makes more power than the comp cam.

In response to the comment made about not gaining sh** from the extra lift...
I also have a few camshafts we've tested with different lobes some with extra lift, or extra exhaust duration. Just because you add extra lift doesn't automatically mean you made better power. I have plenty camshafts that you'd think would do well, but didn't.
That's the awesome thing about testing stuff like this, while to some clown 3-4hp across the board may not sound like much, to some people a few horse while keeping durations the same & advance the same is a great thing.
I'm always amazed how sh*t talkers always jump in here & try to steer the thread off topic. All this data shows is two very similar camshafts advanvced different amounts giving people a idea of what different lobes can do.
Honestly I'm about cured posting dyno results data....

your right I dont need reasurance from anyone about what made better power. I was just trying to provide everyone with some interesting data..

^^i bet they do test all of those but they started with small cams and are just now on the 228 so it might be a while plus its alot of money to test all of these with gas and other prices

Here's the single patterns all together guys. Sorry this is as far as I've made it. For every simple single pattern cam, there's numerous others that we test as splits. What split works best for one intake duration doesn't necessarily work on another.
Here's the 220s single patterns all together.

to everyone saying its not worth switching cams for such little gain, im pretty damn sure TSP isnt trying to sell their new 228 cam to any of the 228r owners. no one in their right mind would switch cams for ~$400 for 5 hp and a few ft lbs across the board. what i would imagine is that they are trying to show new people looking at 228 cams that they are bettering the standard, however much that is. personally, id buy the new 228 cam over the 228r because it makes (more) power all over the board & alot of testing has gone into making it the best it can be at this particular duration. also, im sure many people would do the same as i would. but i dont work for TSP, so this is pure speculation, but it seems common sense to me. just bettering a product that was already great to begin with.
