can i run these cams

[mattsil80wis]

i just got some JWT S3 cams and i was wondering if i could run the cams with my setup

stock turbo at 14lbs

injectors are at 95% duty cycleand maf is almost maxed out

will the cams change any of this?

[karmakaze]

with a 95% duty cycle, cams should be the least of your worries. you don't really want to go over 80%.

turn down the boost some and you will be better off. thats a bit much on a stock turbo anyway.

that is why the stock injectors run 85% stock? yeah plus they like to run hot

[Emperor_Tha]

how do u check injectors effiency. I'm running t25 at 14psi with stock injectors and 300zx maf. I'm taking off like -12 on my safc just to run 11.6

if you don't want answers then don't ask questions.

[karmakaze]

your injector duty cycle is a parameter that can be displayed on the SAFC2.

maybe if u answered the right questioni asked if running the cams would push the system over the edge i never said anything about fixing my duty cycle i just want to know is if the cams are going to change any of these numbers

[karmakaze]

i do not know anything about JWT cams in particular, however, anything that increases the airflow through your engine will affect your injectors and maf.

What is it listed under in the safc2 ? I need to check my duty cycle!!!

+100

increased airflow up top will require more fuel, which your injectors can't give at that IDC...

All cams do is change your power curve and where it hits. for those cams you need new vale springs and possible retainers as well.

but if you are running a stock t25 or t28 then stcok cams will work the best for those turbos efficiency ranges.

what is the duration and lift for those cam?]

i say leave the cams out until you have a turbo to match them.

Most factory SR's run (as I checked in Matt's car) and others in the 85+ duty cycle range. You posted the obvious stuff he knows about, but was just asking a question retaining to the cams affect on the engine.

I've got a fealing the cams at 10 psi will be near the same results as him currently at 14 psi (.93 duty cycle, and 4.98/4.99 MAF).

Also, 85% duty cycle 'myth' is just that. It essentially only applies to old rochester/msd style injectors at this point in the game.

With that said, 13-14 psi is fine for the stock setup with his Walbro and FMIC.

All cams do is change your power curve and where it hits.

It does also inrease airflow, which will require more fuel.

for those cams you need new vale springs and possible retainers as well.

JWT S1->S5 do not require any valvetrain modification. Only their C series cams do. To me, that advantage, along with making the most power, is why JWT cams kick ***.

but if you are running a stock t25 or t28 then stcok cams will work the best for those turbos efficiency ranges.

These cams work excellent in FWD N/A, and t25 and t28 applications, and will undoubtedly work the in the rwd DET using a similar setup. While the turbos do run out of breath, these cams match the midrange torque of the t2 flanged turbos perfectly....

Again, it seems to me that we'll either keep things how they are, or turn the boost down and put the cams in. Time will tell.

IMOThe car needs a JWT ECU/MAF/Injector change first before anythign.

^ cody you need ot geta Job being a Rep for JWT and actually get paid to advertise for them........... OR DO YOU ALREADY?

[mattsil80wis]

thanks cody for answering everyone for me and saving me some time

[Koshin]

not trying to threadjack, but is there a way to moniter injector duty on the SAFC II?? I had the SAFC on my old 1g, but cant seem to find the setting for injector duty in the moniter screen. Thanks

I wish I did. I just like to support awesome products when I can

[Koshin]

Just some advise, you cannot monitor injector duty on the SAFC II. Answered my own question, lol

[supreamS14]

Can any body tell us how we can check our injector duty cycles? Apexi Miltichecker?

I guess it can't be viewed on apexi Afc neo

Buy their cable and download Nissan Data Scan.

It should be a MUST with every swap....

...and why are people still playing with SAFC's?

kids will just never learn that SAFC's are a bomb waiting to happen...its foolish...JWT for life

[codyace]

JWT, Enthalpy, D Jetro....anything is better than the SAFC lol.
