How Many Kw Is A Standard Rb20 Amf Good For

[Bsa]

hey everyone I'm wondering if my rb20 amf will be up to the task my mods are

Td06h-20g turbo 8 cm housing

Turbosmart external gate (17 psi)

Stainless highmount

32gtr intercooler

550 denzo injectors

3 inch exhaust rsr

K&n pod filter in box

Will be getting a tune done just want to know what else I need before I get it done

You mean afm - air flow meter?

Well, short answer, no.

What ECU do you have?

[Bsa]

Yeah my bad i will be running a nistune most likely

[johnbarry88]

nistune + z32

RB20/RB25 AFMs max out at about 200kw (give or take 10kw depending if your willing to take the risk of tuning it outside of it's resolution), if your target is 200kw+ then you will need a Z32 AFM

They are supposed to be about the same as RB25 ones which means that they hit max volts at around 200rwkW......but the common wisdom is that they run out on RB20s at about 180rwkW or so. Mine is about 170rwkW and was sitting on 4.9v or something at max power.

Just had my rb20 tuned with similar mods but standard injectors, 14psi and made only 188rwkw. My next move is obviously z32 afm and some sards

Then we both crack 200 easy i would think

I'm wanting whatever I get out of it hoping over 220 just want to make sure everything is good before I try

I'm pretty sure those turbos are good for over 250rwkw on RB20s.

Isn't it the same as Roys turbo when he was making 265rwkw or so?

Hell, Danny from JMS in Adelaide was making 265rwkW with a TD06 RB20 about 10 years ago.

[Bsa]

Sounds like it will be a good setup then only time will tell should be dynoed in a month or so if I crack 250 I'll be stoked. Should I run cam gears?

[K-LESS]

Correct me if im wrong please, but if it is a colder day or cold night doesnt your afm have more chance of maxing out / reaching maxing voltage compared to if it was a hot day?

[GTSBoy]

Yes. Engine breathes on a volumetric basis but AFM measures on mass basis. Denser air means more mass for each volume breathed in.
