My Latest Dyno R33gts25

[skyla]

Just had my car back on the dyno, after my latest lot of mods. Was hoping for a few more kw than the 117rwkw that my car got but at least it was a gain. Dyno was run in 3rd gear.

My car seems to running a bit lean through the mid range, so might have to invest in a fuel pressure regulator.

And it definatly looks like I need to get some bigger cams or more tuning or something, the power really drops off up the top end.

The next mods I'm looking at is installing an electric fan and installing a bigger throttle body.

Anyway here's my print out

Why in third gear? It should be forth.

Thats a pretty good reading, whats done to it??

Yeah I thought it was a bit funny that they ran the dyno in 3rd, don't know why they did that??? <_<

So far the mods that have been done are, exhaust 2 1/2", extractors, K&N pod filter with cold air intake, custom 3" intake pipe from the pod to the trottle body, and running an after market ECU (GTS link).

would be interesting to compare your dyno to a dyno dynamics readout with someone who has similar mods.

as i personally think that you should be pushing more power.

shouldn't it should be fine to do it in 3rd gear if they configure the dyno for 3rd? but hmm... 4th....

eug

p.s - did u retain the VVT with the GTS Link?

[paulr33]

yeah should be in fourth as the ratio is 4:11

If you have an aftermarket ecu, why did they not tune it better and remove the lean part.

[skyla]

Eug, Yeah I'm a bit disapointed with the 117rwkw I was hoping for over 120rwkw, but it is at least a step in the right direction.

Yep it's still running the vvt with the link ecu.

Al, when the ecu was installed and tuned earlier this year it was set up with different mods to what I have now, when I changed to the custom intake and added the pod filter it obviously changed all the air/fuel ratios and the car needs to go back in for more tuning to correct this. I have been putting it off untill I have got more of my planned mods done, I have cams, throttle body and a few other bit's to be done before it goes back to the tuners.

Fair enough

[Br4nchi3]

I thought stock NA 33 (rb25de) has 140kw or is that at the fly?

[NA_R33]

it supposed to... were talking about power at the wheels in here... power at the flywheel is different due to gear ratios and loss through the drivetrain.

[Br4nchi3]

Yeah I know you guys are talkin rwkw, was just wondering. So I take it 140kw is at the fly not the wheels, thx. (thought so)

[unarmed_skyline]

ey, skyla is the ecu your using ment for a turbo or non-turbo, im looking into getting a power-fc ecu but its ment for a turbo n they dont make an na one will it still work?????

[skyla]

The ECU (GTS link) I'm using is most commonly used on turbo skylines.

I'm not familiar with the Apexi power FC, but from what I have heard are better than the link ecu's. I can't see why they couldn't be used on a N/A car, although better to find someone that knows for sure.
