please give feedback on cams

Thanks for the feedback!

CDIraughn- We have all of the testing that we needed done already on the 188-220. I appreciate the offer. All we need a bit of help with at the moment is the 178-208.
 
Will the cam data shown below be similar on a 24V motor or different? Also, where do you anticipate the 178/208 falling in this crowd? I would have posted on your forum, but registration is disabled. :D

stock 12v cam black, 181210 blue, 188/220 light green, 200/220 green. This is all of the same runs as the above graph except plotted as a function of time instead of rpm. The above graph shows how much horsepower is made at each rpm where this shows how fast the HP was made. Notice how fast the power is made using our cam as opposed to the stock cam. The runs are finished before the stock cam even starts to light the chargers!

Sorry I had to shut down registration on my forum. Spammers kept posting up about Kim Kardashians sex tape and how Viagra will make you the man etc. Sad that I have to shut it down sometimes.


With the 3rd generation 178-208 on a 106.5 LSA, I believe that you will see it spooling earlier than the 181-210 but a littel bit slower than the 188-220. The reason is that the 178 intake due to the new ramp rate and low lift profile, will allow it to trap the most air of any cam we have at low rpm. This will make power at low rpm great. Due to it's duration at .100" and .200" we expect it to pull hard to 3,000-3500rpm. On the exhaust side, it will not use as much exhaust energy to spool the chargers so it will not hit as hard as the 188-220 because it opens the exhaust later.

Does this mean more air and less smoke under normal driving?

What, you don't want to take advantage of the HUGE viagra sale? :hehe:
 
yes it will provide more air than any cam we sell at the lower rpms you normally drive. That is the upside, the rpm you are at 99% of the time it will provide much more air. The downside, although it will provide more power than the stock cam above 3,000 rpm, it will not be as good as the other "performance cams" we sell. We are getting more requests for economy or performance instead of economy and performance. In part number terms we are seeing people either want the 178-208 style cam or the 188-220 cam. The 181-210 is a great cam as it tries to do both, but we want to provide more specific cams for exactly what our customers want. This is where the different cams come in. We are having more and more customers ask for cams that peak in a specific rpm range.

This is also why we came up with our 55mm cores for the big 230-240 .406", .420".

Viagra sale, I hope it's a while before I need that

178-208 sounds good. Let me know when they are ready. I'll try to bribe Trent into helping me put it in and I'll try to get you some numbers. I won't run above 3000 anyway so any performance above that is a waste of $$$ for me. I need help between 1700 and 2500. There is a permanent dyno 19 miles west of me to get you before and after number if you are interested....but I would assume he is going to charge me $100 for the info and it makes no difference to me what a machine says. Your choice. :D
 
I'm still in shock how well the 181/210 ties everything together in my setup. I now can add a lot duration without a smoke show and loss of power. Need to get on the dyno, because I'm sure it added a couple more hp.
Great job on these cams, and it's been a pleasure doing business with Hamilton Cams.
 
Yes, between the cam, larger valves and port/polish work, and the 66/72 charger, getting ready to change the delivery valves for some bigger ones
 
Have you picked your test people yet for the 178? It is exactly like what I am looking for. I keep checking and wondering if I made the list.
 
heres a video of one of Hamiltons 181/210s. As soon as time and money allow iam going to listen to zach and go to the 188/220 to really push the charger. Zach has been a really big help this season and has gone above and beyond customer service.

i leave the line as close to 4k as i can and it usually picks right back up to 4k going down the track. For a CR this truck sounds way different than any other one ive heard
