RPM..on ctr cams

[shaneb]

where do you feel the power of the ctr cams on the prm range? I going to put ctr's in my 91 hatch w/b16a.... but at the same time leave the stock contianers and springs...(for now).. what would be a safe red line at? and would the ctrs give me any power , more than the stock ones at 4 -8 or 8 1/2?

 

[E_SolSi]

stock springs i wouldnt go any higher than normal redline

8200rpms with oem B16 springs and retainers is highest with CTR intake/ITR exhaust.

9000rpms is where the CTR intake/ITR exhaust combo make power until.


nothing higher, if you want higher go with what options I posted in the board up top.

and mind you, 9k will need a cam gear tune to give a little more overlap.

i thought those cams only made power until about 8500-8600. ive been looking for dynos of the ctr against other vtec cams.

jdmilan......
i have a b16a head and i wanted to place skunk ti retainers, type r valves and valve springs. would this be enough to rev to say 9000 with itr cams.

stock cam gear setting, yes. which is why i said above. you need to dial in more overlap on the cam gear... liek +3 intake, +2 exhaust or something to get it to make power that high, but doing so sacrifieces mid and low end power.

if you're going to do the work of replacing the valve springs, you might as well do it right, and go with toda or jun or skunk2 springs as well. ITR's aren't that stiff.... and frankly, while it WILL hold 9k every now and again, i'd feel much more secure with a stronger and longer spring in there to reduce the risk of floating a valve.

ive been reading lots of reviews on the jun valvetrain products and while their cams are badass their springs suck... most people with jun cams are running toda springs because they hold up better

 

[JDMilan]

I agree with pissed that if you want to run for now oem R cams then with adjustment you can max out power till 9000rpms. If you plan on going with oem R cams now and then you really want to upgrade in the future then upgrade to a much stiffer spring and tit. retainer combination so that you won't need install then take out and then reinstall the springs and retainers.

no, i had cam gears with my ctr's and they were dropping off past 8400

 

[JDMilan]

just saw a dyno on importreview with ctr cams making power up till 8800rpm but they started to drop off a little just before that.

*shrug* every motor responds differently too... cams only go so far

 

[JDMilan]

this is true also ^

mine loose power at 8k w/ my lsvtec and they lost power at 8250 with my b16

crower makes a roller-follower system that seems very impressive all around
