I've heard that with CTR cams, it is best to raise the VTEC engagement to 5700rpm. My question is would this also apply when running just the CTR intake cam on a B16?

stock is 5500 i lowered mine to 5400 with stock cams maybe you should bump yours up to 5600?

you can always try both and see what happens and what you like

it all depends on the type of intake, exhaust, header and few other things.


for example on my b18c 5100rpm is best point on my buddys its closer to 5500rpm and so on. it all depends on many factors.

5200-5700rpm is usually fine on most motors

Well my setup is as follows:
CTR intake cam
Iceman CAI
DC 4-1 header
Thermal R&D 2 1/4" exhaust
test pipe
B&M fuel pressure reg. @ 48psi(vac. line on)

Ever since I got the CTR intake cam installed, whenever I go to the track it seems that my car has a dip in power before VTEC crossover(stock 5400 rpm). When I launch, I fall out of VTEC range and have to pull back into it unlike before. Should I raise or lower the crossover to even out the power curve?

Ur best bet is to get it dyno tuned.

I know I should take it to the dyno to get the A/F ratios down, but I've heard most people say that its best to have crossover set at 5700 rpm. Does this apply even with just the CTR intake cam on a B16?

with any intake/exhaust cam on any vtec head, its best to dyno tune to see where the cam like to unleash its power. and stuff

Doesn't matter what most people say..not every car is the same. I'm saying, if you have access to a dyno...that'll be the best decision. If not, then I guess the best thing to do is see how others have theirs setup with fairly the same mods.
