Cammed Motors Specs + DYNO Graph Mandatory

[dsp26]

^^^we'll see how tuning goes.. the BCs were supposed to be the ultimate midrange cams... i was honestly going to get skunks though before i picked these up for the price i got em.

i reckon i'm missing at least 5kw where the vtec crossover dips.. by the looks of it, it'll probably be happy around 6200rpm... but i mean, the dip brings the power back flat to stock for about 500rpm after the actual crossover which sucks coz i can actually feel 'vtak kick in yo' coz of the surge after it :/

lol i still rekon you should have went with the toda spec b's... thats my opinion so dnt start any shit here

you would have ended up with alot more power mid range and top end...

the bc cams are good though nice smooth power curve... very good choice

How much power you making with your b16a?

[tinkerbell]

Go the BC spec 3. They work well on a stock motor.

they work fine on B20VTEC too

Yeah we know that too. Very good mild cams.

dsp26 have you got it tuned yet how much power r you making?? get a dyno sheet up

[tinkerbell]

i am aiming for 132kW next time i goto the dyno...

nope not yet, was on the dyno on the weekend to fix some issues with dizzy timing and idle, was a trade-off, get idle a tad stable through advancing and lose power and vice versa, advanced it back to 17* which would have brought me back down to my 99wkw figure from the workshop, at least i can idle and warm it at 5am while i get ready for gym

i am aiming for 132kW next time i goto the dyno...

what else have you done since your last 2 dynos? you going to the Toda one in Sept? for some reason I always thought you were a Melb member

[delsol9000rpms]

so when are you gonnna have it fully tuned with a propper computer like hondata or crome or something?

[tinkerbell]

what else have you done since your last 2 dynos?

adding a set of hy-tech replica tri-Y 4-2-1's and a 200 cell cat... to replace the JDM 4-1's and the 5yr old 2.5in cat...

plus a higher rev limit (previous dyno was only tuned to 8000), plus properly lashed valves, plus properly impedance matched injectors, plus a pocket full of kryptonite...

***DSP26's notes***

after spending $XXXX amount to get my car running, I understand now that those who were saying get a better Final Drive ratio are correct as it moves the entire powerband across to the left. Only reason i don't regret this build was coz my engine needed it... but in terms of first performance mod, final drive is better!!

dude,

i know your running itr muffler, whats the noise level? looking to buy itr muffler

[dsp26]

bump this thread.

anyone else? does anyone have sheets with the torque curve... i actually wanna see the 'powerband'... i have less than 1500rpm and 1500rpm is supposed to be like the average?? with some exceptional tunes having around a 3000rpm powerband of peak torque

dude,

i know your running itr muffler, whats the noise level? looking to buy itr muffler

dB wise its quiet.. but it sounds like shit.. has the shitty buzzing noise... either my resonator is shot or the muffler is... oh and pm next time... irrelevant to this thread
