Standered Afms

[Adz2332]

Just a quickie...

What will the standered AFMs on a GTR R33 support?

[R31Nismoid]

Depends how good your tuner is

Can be over 300

[Adz2332]

excellent thanks for that... so hoping for around 280... mayb 300kws the afms should be fine.... there was someone on here selling 80mm afms with plugs for $300. but if they should get 300 im all good

Because im trying to rulw things out that would stop me from reaching the 300kws mark...

Im guessing the set up will get me around 280kws MAYB 300...

Id love the 300 so just trying to work out what would hold me back...

maybe list all your mods and someone could go through and tell you what you would need to upgrade to make that power

Rule of thumb for Air Flow meters RWKW & Engine BHP

------ ---- OD ---- RWKW ---- RWKW ---- BHP ------ BHP

No of AFM's ---- ------- 1 -------- 2 -------- 1 -------- 2

RB26 ------ 65 ------ 149 ------ 299 ------ 271 ------ 474

RB20/25 --- 80 ------ 226 ------ 453 ------ 376 ------ 683

Z32 ------- 80 ------ 255 ------ 511 ------ 415 ------ 763

Q45 ------- 90 ------ 302 ------ 605 ------ 479 ------ 890

I blew those numbers outta the water a while ago making 270rwkw @ 17psi (pump) and then 369rwkw @ 24psi (race fuel) using a Z32

Hey Ash,

Yah, I do rem reading about that somwhere. Is there an easy link regarding it somwhere? (just outa interest)

Was the unit still putting out a rising voltage at that power level, or had it maxed, and you tuner was tuning around it?

ooops forgot to add N1 steel wheel turbos and tomei cam gears

He was talking about 300hp, not 300kw for a stocker, although I think it's something closer to 340hp or so at the motor.

I think Paul's numbers are a bit off also. I only pulled 4800mv through it at 400rwhp, and I'm ballpark 500rwhp now and pulling 4995mv through it on cold nights. I know it's a 5v sensor, but I've seen people go over that (to like 5100mv) making 530rwhp. I have sucked water into my intake after a carwash before and it pegged it at 5150mv.

Nismoid, what kind of voltage are you pulling at that power level?

[R31Nismoid]

I was talking 300rwkw, not hp.

Michael - a thread doesnt come to mind mate.

And i honestly cant remember if we'd tuned 'past' the AFM or not on the 369rwkw run. I know it was still fine for the 270rwkw run however.

[Cjmartz2k]

I was talking 300rwkw, not hp.

O, my mistake. 300rwkw is around 450hp at the motor, right?

[Rav]

I have standed afm's on my RB26 engine and iam pushing just over 300kws.

[Cjmartz2k]

O jeez, I just realized we were talking about dual RB26 meters, not a single RB20/25. Duh

[GeeTR]

No stress Ash, cheers bud!

[paulr33]

hi,

those numbers are very old - feel free to suggest new updated #'s and ill update my site

[GTR1993]

Are the numbers what you can make approximately when u hit the last load cell, or just what you will pull through the afm, because at the end of the day you can load that last cell up with fuel and will be "fine" and make much more power then it technically can read.

They are my numbers determined in the tuning of well over 40 Skylines since 1999. They are RWKW at 5.1 volts on a properly calibrated Dyno Dynamics at zero knock with circuit racing safe A/F ratios and using 98 ron pump fuel. They do not allow for happy dynos, hub dynos, boost spikes, race fuel, dangerous A/F ratios or smart tuning past 5.1 volts.

I have an R32 GTR. Air Flow meters are still standard (other parts not standard but as we are talking just afm's didnt feel necessary to list) and on 24psi I am putting out 341kw at the wheels. My tuner is telling me however that the afm's are now at or close enough too their max.

[Adz2332]

also didnt add Kakimoto Regu 06&R exhaust, high flow cat, and JJr front pipe....

My tuner said this set up would be around 280kws..... so im confused whats needed for the 300kws :S
