350awkw Achievable Without Z32's

[R33-RB26DETT]

Hi

The boys over at Chasers Motorsport have told me that i need to upgrade my stock afm on my r33 gtr to attain this power along with my turbo upgrade - is this true?

The reason i ask is because in the RB26 Dyno Results page there are heaps of ppl with 350+ awkw's that haven't listed z32's?

Nismo/Z32's are required.

Can get away without it, but yeah, not advisable.

You'll probably find people have just forgotten to put that in as its a 'given' when running PFC etc

Your tuner can tune around it and use standard AFMs, but if your doing the upgrades may as well include the Nismo AFM's they bolt straight in, and can give a better tune.

[Adz2332]

SO anything up to 350kws standered ones are fine

[R31Nismoid]

you could do 400rwkw, point is its not advisable, they max around 300rwkw or so

[N1GTR]

Or use an ECU that doesnt need AFM's

[R33-RB26DETT]

Forgive my ignorance, but..

if it can be done but they are 'maxing out' what will happen? i.e worst case scenario?

p.s how much can i sell my current AFM now?

[R31Nismoid]

Worst case - dead motor probably in the most extreme scenario

End of the day, its what, $600 more, if you've just upgraded turbos etc its part and parcel.

Owning a GTR isnt cheap, let alone modifying one.

I also hope your motor is healthy, as rebuilds aren't cheap either

the worst case with maxing afms is you run out of load points, so it runs map sensor style

once it maxes, load never incrases, so you have less load points to play with

if it happens at say 4000rpm then from that point onwards you only have say 6 more points on the tune to play with

whereas if it wasnt maxing you would say maybe 40+ points to play with.

so less granulatarity = more dull tune to deal with the wide scope

how does the d jetro benifit (running about 380 AWKW) over using AFMs?

cheers

[R31Nismoid]

Well you dont need AFM's, only benefit really, but then you dont have as good vision...

Really depends on who's tuning it

[Betz]

mine came up pretty good, were around 80% duty @ 290rwk about the same for inj duty aswel, my tuner said many tap out around that and they loose safety margin as you start to hit max inj and turbine efficiency if you push harder.

heh, give it a crack if your chasing power and have the money for a rebuild

[R33-RB26DETT]

nah comp test results showed perfect on all cylinders thus i want reliability so i will have to get them for sure.

yeah should not hurt the engine if tuned properly, just make the under load tune at top end less dynamic

RB20/25 AFM's work too.
