Dyno Day 22 September 2007 Saturday

[Michele]

Who is going to cook the bbq? Any takers?

[a20089]

Not sure there's a great demand for the BBQ, maybe save it for a cruise to a picnic spot?

Saying that if most people coming would like to have a BBQ, I'll try and find someone to run it.

A20089, pm sent, paid for my ute to go on today

Hey John, I spoke to you about half an hour ago I'm in with my R33 GTST, and I *might* talk my brother into bringing his Integra VTIR.

Will send the moola shortly!

Sorry for the noob question - but can anyone confirm if there will be a printout rather than just on screen display and explain the basic run through of the set up and whats involved? Have attended dyno days before as a spectator but never payed too much attention to the precautions, whats required of the car and what not....

Cheers

You rock up, make sure you're paid up, get a place on the list, make sure you line up ur car when it's meant to be dyno'ed, stand back and watch them rev. Get your print out (I've never seen a dyno day without print-outs, please confirm John), you look at your printout and go 'hey! xxx kw, not bad!' and then 1 week later you wonder what you can do for more power

Hey Towlie,

Yes you will get a printout.

We do a quick check to make sure the car doesnt run lean then we do 2 power runs and give you a print of the power.

The print will display power, you AFR and Boost.

If you would like to know anything else just ask.

Regrads,

Cristian

Cristian,

RE the printouts - I've seen some with kW/AFR/Nm plotted against RPM and speed. Engine speed doesn't really mean too much to me (mechanical neophyte), whereas RPM does. And the last dyno I had was kW + AFR vs RPM. Ideally I'd like kW + Nm vs RPM. Car's stockish, so don't care about boost, feels like it's holding fine to redline. Is that a viable combo?

Cheers,

Ben

Ben,

That can be done but remind me as my memory will fail me by then

For me personally i think KW + AFR vs Boost is great for anyone wanting to see how safe there mixtures are and if it's over boosting. In saying that it is also cool to know how much torque your car is making and at what RPM your car is no longer making peak power, speed means nothing as far as i am concerned.

[sl33py]

Cristian: Cool, I'll remind you.

I agree leech, but the only mod I've got is full exhaust/cat and it's been running healthy for the past 2 years (yes!: *yawn*), so chances of overboosting are pretty much zip More interested in torque this time. When I do my first proper mod (ECU in the next 6 months), then I'll wanna know AFRs again

[leech_]

i know what you mean see i am at the first stage putting a new turbo back exhaust that's why i want to just check all my mixtures and boost

[Cristian]

This is what our dyno prints look like for most cars that we run

It will give you an idead of what yours will look like

[sl33py]

Cool, that has everything! Looks like I won't have to ask for anything in particular

that's a great sheet covers everything stupid question but how does the dyno know what your tacho is reading. I understand the speed would be easy as the rollers will tell you that but yes bit lost on the rpm.

RPM is generally picked up from 3 different places depending on the type of car.

It will either come from:

A plug lead

Injector

-ve side of coil

For a skyline, will come from the injector easiest way.

Say where are these GTR owners in Canberra!!

There all being soft, they are afraid my stock XT forester will beat them (with all of it's estimated 120 - 130kw at all 4's)

[Baconer]

If i dont beat your forester ill be pissed
