First Dyno Run Ever

[fletch63]

Hi all,

Just had my first dyno run (on any car I've owned) so excuse my excitement

Just wondering if anyone with experience can look at the dyno sheet and tell me is is good or bad?

Looks to me like torque drops off a bit too dramatically but a bit of a newby so.......

Anyway here it is.

R33 GTR with 2860's 3" catback and pod filters.......all else is stock (tune by PFC)

At about 17lb boost got 333HP (almost 250KW) at the wheels (injectors at 92-94%)

Any opinions?dyno.pdf

Without knowing which 2860s (there are 3 or 4), impossible to tell really.

Torque always drops off. So no issue there

Yeah still don't know which 2860's I have!

Only had the car a few months

Regardless, does the graph look OK/acceptable?

[R31Nismoid]

Looks ok.

Given the lack of detail surrounding the actual turbos you have, can't say much more really

Took it for a blast last night

Very impressed

I think it's a bit low really for any 2860 but as long as ur happy when u drive it that's the main thing in the end

[Anfanee]

that looks right. Most likely AFM or something like that are maxed out.

[fletch63]

I have found they are 2860-7's

Injectors are nearly maxed out and AFM's apparently have a bit more in them.

Very smooth down low now and revs out nicely

Next injectors, AFM's and maybe cam gears.........on to 300KW+ at the wheels

I'm on -7s with stock AFMs, 550cc injectors and making 305kw at 17psi. Clean stock injectors might get you up to 280kw, but its not worth cleaning them now, just go for new ones. You'll prob get a set of injectors for ~$600. Nismo AFMs bolt in and will be ~$700-800, but might not be worth it unless you want to push past 300kws.

FWIW you can tune past the AFMs measurement range, but then the ECU has to make its decisions somewhat blinded, so cant properly compensate for differences in conditions.
