R33 235rwkw @ 16psi

[danieltangtc]

Hi guys, just came back from a tune at tilbrooks in adelaide by martin.

Tune was done at 16psi....at first we got 240 rwkw at 18psi but i decided to settle for 235rwkw @ 16psi as martin said r33 conrods and internals will not last too long will too high boost.

Your power curve looks nice and smooth, but your AFR's seem very rough

[[HOTNXR]]

DOH! hehe oh ok now i see it... :-)

[Trust33]

Cool.

How are the 10'' tyres holding up.

OK, not picking on the poster of this comment, I have deleted who it was for that reason.

But I am getting very tired of this slavish belief that having a flat A/F ratio trace is somehow a reflection of good tuning. It's NOT, all it indicates is the guy doing the tuning decided on an A/F ratio and then tuned to it. Any idiot can do that.

But (there is always a but) that ASSUMES that the one A/F ratio results in the best power at that rpm. And we all know that is CRAP, 12.X to 1 may well yield more power than 12.Y to 1 at certain rpm points. A GOOD tuner aims for a smooth power curve, not a smooth A/F ratio trace.

I know which I would much rather have.

cheers

true, i would rather a curve that doesnt have a dip in it anywhere and is smooth.

Thanks for the info SK...

for those who wanna know, tuning was done by Martin Donnon in Adelaide through Tilbrooks Dyno...top bloke...knows his stuff!

Did you flow test your Nismo 555's? and did they all come in at about the same readings?

[JeeTeeEss25Tee]

Man that's a very very smooth curve. Congrats. At what rpm does it make full boost? (16 psi)

[SLY33]

excellent result from the 2530, thats a great looking curve gotta be happy.

id say hes seeing 16psi by about 3800-3900rpm, as id see ~18+ at 4grand.

Actually, lets do an SK and do some maths from the looks of the curve, he hits full boost at about ~110km/h. divide by 29 gives us 3793rpm (give or take, assuming 245/45/17) :lol:

saw your car there today by the way

Nope...I did not flow test them, they came with a flow test report. Average flow was 565. Minimun was about 560 I think.
