Awesome . Will you be posting graphs so we can see the different curves associated with the different grinds ?

 

[Joesixpack]

Probably no valve covers, 2 bolts on the front cover, etc, etc.

 

[JaMan]

Zach where are you testing? At the shop?

 

[Hamilton Cams]

Waco, Ultimate motorsports. It is an appointment only shop that mainly does LSX engines. Dynocom 1800SE with eddy brake

Electric fan, no shroud, all bolts three guys. I have video of some of the runs, really nothing to see we have exhaust being piped out. Too many nice cars to have to wash later.

Awesome info Zach! Graphs would rock but bottomline is you will have more info to share with customers.

 

[Woodchuck]

How 'bout throwing a stock one in the lineup too as a baseline comparison.

That would interest me too, if you guys have the time. That would give me an idea since I still run a stock cam and head.

 

[cummins724]

Another vote for stock cam. lol keep him busy.

 

[Countryboy07]

This is awesome! Can't wait to see the rest of the results.

Here is the runs with the
188/220 as the leader so far
206/220 is second. It's lift is above what the stock head will flow and the bigger intake duration bleeds off more cylinder pressure at lower rpm's but if we were running to 5500rpm you would see it shine. If you will look above 4k it starts to top the rest.
181/210 is the lowest no surprise. It spools great but it is also most effecient with the smaller exhaust. 220 exhaust although not as efficient for a daily driver spools the chargers fast!

5.5 hours and we are setting the valves on the stock 12v cam now.

I will have the sheets up in 30 minutes or so. If we have time we will show how the other guys cam rolls.
