RB20 - Z32 or Stock AFM for 230rwkw?

[Chris32]

Getting ready to put all my bits I have collected over the last 6 months on -

they include -

RB20 Power FC

GTR 440cc injectors and resistor pack

Stainless Steel exhaust manifold

Maybe GTR cams later on $$ permitting

Due to my turbo being a bit of a mystery (told is was a 2510, but looks to be either 2530/35/40 but due to tag no matching up no one know) All I know is it makes dead on 200rwkw at 0.9bar and comes on boost at about 4-4500rpm

I am hoping for a conservative 220rwkw, running around 18psi boost, maybe 230 with a splash of toluene for dyno days etc

I am usure weather to use the stock AFM, or upgrade to a Z32 unit, as thelast thing I want is to get it all running on the dyno and find out that the AFM is maxed out...........

Whats everyones opinion? I have read post from Sydneykid that says it should be good for 226rwkw

Has anyone else made around that power with the stock AFM, as if its doesn't need replacing, I won't bother!

no question use a z32 no point in skimping at this stage it will give a much better resolution in the tune.

Yeah was thinking that myself, cheers.

I know Clint made 235rwkw with the RB20 AFM, but I guess with the Z32, there will be more 'resolution' so to speak

chris i had a z32 one, better to be safe

[Chris32]

Cheers for the replys, Clint, I thought you had a RB20 AFM - my mistake

I bought one this morning, so I have everything now

so you still have to run the AFM with a PFC then, its a shame you didn't get a ecu that did away with the AFM and kill 2 birds with one buy...good luck with it all..

Well my original plan was to run a Microtech, but I managed to pick up the PFC for a very reasonable price, so I went with that. Wolf3D crossed my mind, but a tuner I spoke to that would be the one having to tune it reckons they where best left alone........

Plus its plug and play, if I get defected etc I can jsut plug the old computer back in and change a few things

I don't think the AFM poses much of a problem/restriction at these type of power levels
