Dyno Results: 196rwkw For Basically Stock Rb25det

[Taso84]

The leaner it gets the higher the number.

Yea exactly and mine was staying on 13 the whole time. The other guy was saying that if it was the fuel pump the AFR would keep rising... I don't see how tho

[GreddyGo]

I Just got my NEO dyno'd,

I got 179rwkw with a catback and apexi filter.

The heatsoak was pretty bad, the next run after that I only got 164.

From the mods you have it's possible.

Cheers

i think you are right there. i'd say its probably the fuel pressure regulator.

[Taso84]

should i just get another stock 1 or is there a special brand FPR that is recomended?

[Cubes]

Thats definitely a strange leanout..

Flat 13 all the way through.

Could it be a bung FPR?

[Taso84]

mayb i should just replace the FPR 1st and see if it fixes it

Should i be getting any particular brand or just get a stock1?

nismo ones are cheap and well tested .. and just fit inplace of the stock one easily

[Cubes]

What did the tuner suggest?

havent spoken to him yet, but nismo is the way t go huh>?

[Cubes]

Depends on your long term goals.

If you don't plan to throw a highflow on it just grab another cheap (if they are cheap that is) stock item from a wreckers and try.

Otherwise.. grab a nismo item. They work well and are well priced. Grab one from nengun/perfectrun and the like.

shameless plug

i have a nismo FPR left over for sale brand new boxed $150 posted to you express

pm me if your intersted

[Busky2k]

You can't just throw a FPR onto a stock ECU. It'll mess up the fueling on anything but full throttle.

Also AFRs at 13 wouldn't be responsible for the high power. The power difference say between 12 and 13 might only be 2-5% max. 196rwkw at 8.5psi.. sounds like an RB30 haha.

[Taso84]

U reckon? How would i check it its got a rb30 bottom end?

[paulr33]

its not an rb30

hahahahaha

what i find odd is that the AFRs are almost dead flat all the way through, even though it is lean

maybe its not actually a stock ECU? have you checked what it looks like for some kind of sticker? or opened it even?

Nah havent checked it, i jus assumed it was stock i guess. I'll do that this weekend and let u guys know. ECU is located under passenger side kick panel right?

[rb26s13]

im thinking its been chipped.. those afr's are to straight for dead fuel pump or shonky fpr

[rb26s13]

oh and also corrections wouldnt have been applied to that dyno sheet i dont think as the AT and IT are the same.. so obviously the air temp sensor wasnt in place..

[WazR32GTSt]

yeah but if anything that would make the figures more realistic..

its when IT is way higher than AT that you see higher figures, so with the values around the same the computer won't apply much (any?) correction...
