Dyno Graph

[EeLeYe]

Hey All,

I've recently had my car tuned and aren't sure if this is what I should be getting. I've read other posts where people have been achieving more power on less boost and similar mods.

My car is an R33 SII

PowerFC

Kakimoto catback exhaust

Catco Hi Flo Cat

FLYN Bellmouth Dump/front pipe

Stealth FMIC

Solenoid Bleed Type Boost Controller

K&N Panel Filter

All else is stock

Getting 189.5kw at the treads with 13psi. The tuner also said if I had a Wolf3D, I'd be getting around 210kw.

Any info is appreciated.

Thanks heaps.

what boost?

[EeLeYe]

13psi

The power is fine for those mods but your tuner's claim is utter rubbish.

woops just saw it in your first post. Yeah as Adrian has said the power is OK depending on his dyno. dynos will read +/- up to 10kw.

the average is 195kw for those mods so you're not far off.

I would have thought that on 13psi you should easily be up at 200Kw.

It could just be a low reading dyno

The dyno is fine, look at the power nose dive. I'd like to see a chart of the AFR's. Can also be ignition timing. Nose dives way too early.

[-Stokesy-]

Also, I agree with 2rismo, getting a wolf would make sweet f*** all difference.

[Ryanrb25]

Must have AFR's up there to have half a chance of telling if your tune is fine or not.

if he backed off timing it would have probably been for the safety of the motor which again explains the slightly lower power reading

[Ryanrb25]

dont worry about the torque...just get the power curve and AFR's on the same chart to compare. If it's way too rich in the top end it will cause it to nose dive. And like mentioned the timing could be pulled right out in the high rpm to allow a safer tune.

[EeLeYe]

Thanks heaps guys. I appreciate the feedback.

I'll go back and ask for the AFR graph when I get a chance. My tuner said he's saved the maps so it shouldn't be a problem.

May as well ask for a torque curve too.

[Pattygtst]

that power is right on the money

[EeLeYe]

I'll post it up when I get the graph. Stay tuned for more

[Ryanrb25]

Well that's why we wanna see the afr's..to see if it is...Seen at least 10-15rwkw more out of a simular setup...so that's why we wanna look.

BAHAHAHAHAHAHA

You'll also note that the top end is only running 10psi. The boost drop off in the top end is common with standard turbochargers when pushed hard and can be overcome with a better boost controller.

sales pitch lol

[Ryanrb25]

what's funny is how many people would actually believe him and fork out cash only for him to fit it and wind some timing into it and get a better result...He's happy he's got his cash and the customer is happy but none the wiser of his easy earnings.

Has anyone else noticed that the boost drops off from 13 to 10?

I just got mone retuned with a stock turbo and injectors i have a walbro 255 and a sard fpr also a FMIC and a full exhaust from the turbo back with a microtech lt10's and am having the same issues with boost. Running 12 psi it spikes to 13 then bleeds right back quickly to 10 psi but i still made 203.6rwkw.

I would say your power is a little off the pace or mine is high i am not sure.

Although my power curve is more agressive then this. Maybe my turbo has been high flowed?
