Not All 224 Camshafts Are Equal... Engine Dyno Data INSIDE!!

Here's a engine dyno data sheet for you guys to look over. This is where we compared & built baseline data of 224 duration camshafts so we can check advance for best average power & build a nice baseline for our newest LS camshaft.

This comparison shows the following camshafts on the same engine same mods

Thunder 224/224 114 Camshaft
TSP 224R 114 Camshaft
TSP 224R 112 Camshaft
Baseline Stock LS1 Camshaft

From testing we did with these camshafts at different advance points we were able to maximize average power across the board for guys looking for nice hp gains across the board.

After creating these baselines we tested lots of new camshaft combos & settled on the all new TSP 224/227 camshaft using all new custom Texas Speed lobes. The new TSP camshaft is a 224/227 .615"/605 112. This camshaft helps to maximize power potential using 224 intake duration.
*also included is the new 224 TSP lobe as a single pattern** (run 59)

The new 224/227 camshaft is now available for shipping & works great with the PAC Single Springs!!!

Thats a pretty cool and informative comparison. Thanks for sharing. Seems like a lot of people are going back to the smaller cams. This comparsion should help someone who is sitting on the fence go ahead with a cam swap that they have been contemplating.

Today we are starting some more cam testing in the 228º intake duration range. Head comparisons are definitely on the agenda after we're done with the cam only tests

Yea, we've seen the market gradually swaying towards the DD type cams and focusing on street manners more and more so we're all over those as well. We've never JUST offered the huge camshafts that set ET records

LS6 intake, stock 853 heads, bone stock LS1 short-block, stock balancer, and Kooks 1 7/8" engine dyno headers.

Nice comparison guys but wondering why the dip in torque around 3,800 to 3,900 rpm's? I saw the same thing on the 220R that was posted. Do these cams have no degree advancement in them at all?

Thanks!

That's something we're looking farther into and will be doing more testing on to clean up!

Could that dip have anything to do with the throttle body or headers? Is the throttle body ported at all. Would be interesting to see if it has something to do with primary length.

It is a stock unported TB. It is very likely due to something in the intake and/or exhaust tract...we haven't got into that testing and chasing that issue yet. It is there with the stock camshaft and all though. We've got some new software to do simulations on that calculate intake and exhaust pressures, flow characteristics and velocity, etc as well that will be helping us pin it down I hope.

I will be keeping my eye out on these new smaller cams.

Do you guys have any new cams for FI yet?

I just noticed you are using 1 7/8" headers. Any chance you could swap over to 1 3/4" headers and see if that takes care of the dip? I'm sure you guys have a set sitting around somewhere.

We have a ton of headers here, but it's not as easy as just swapping since the dyno is built around these engine dyno headers. One day soon though, we'll get to that and figure out a way to do some header swap tests. We're more focused on cam testing and such currently. But that is a good idea and something we're interested in doing!

Looks like I wont be testing anymore for a day or two. I only test when my D.A. is within 200-250 ft. Even though the numbers are corrected, I've found that's the best way to try to keep testing as acurate as I can.
