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

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.

So these are setups that normally put down 370-385hp at the rear wheels. I have not seen many cam only setups with 224 cams and no underdrive pulley put down much more than that. Somewhere around 80hp loss for an M6 it looks like, quite interesting.
Also are you guys tuning each setup or just slapping them in there and dynoing?

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!
Thanks!

Yes, every aftermarket cam we've tested so far (many of ours and about 6 competitor's so far) have had that dip....only the stock cam did not show it there, but it did have that large dip just earlier in the powerband as seen in the graph above (about 3200-4000rpm whereas the 224 cams all showed it about 3500-4300rpm). That's something we're looking farther into and will be doing more testing on to clean up!

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.

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.
