Stock 1.6 owns 1.8s graph inside
 

Dyno results from yesterdays run. From a 1.6l with minor homemade headwork, stock internals, t25sr20 turbo, water to air cooler, 2.5" exhaust with artech manifold. Ran at 11.5psi.

On a dynojet 424lcx

Looks good
Really wish that their rpm pickup was working, hate not having everithing on the plot

Yes for how much we paid that's the least they could have done for us

Nex time we schedule dyno time we need to have them agree that everithing will b in working order

Here is a 4th gear log I did today. As you can see 180kpa @ 3400rpms. It spools so fast for a journal bearing turbo.

I'm waiting for a similarity modded 1.8 to dyno lower...

Curly, I have to look at the timing table you gave me and compare it to how mine ended up.

Do you have the actual .drf files Brian and Harold? I'd like to look at mine in comparison.

My timing was crazy low, my cae is a ticking time bomb or i had lower than 93 octane on it.
Send my your email address and ill email you my files

Is that before or after the tune Harold? How did the in-car tuning with Scott go afterwards?

What i don't understand is that rpm pickup was working just fine on both Steves' cars. We were getting torque numbers out of both.

^ +1.

And I am on stock coils, wasted spark even!

Brian, can you do a street pull from 2k rpm in 4th gear for the purposes of plugging into virtualDyno? I am curious what it says.

Maybe because Harold and I have toyota/gm coils and they had stock ignition

There is one in this thread. Can you translate it to virtual dyno? My car weights about 2250 I weight 170

Can you upload the .msl file itself? I'd be happy to post the results. Or you can email it to me. You still have my email correct?

The car is good after Scott's tune but he had to pull a bunch of timing from all the cylinders and some additional timing from 2 and even more on 3, all this without much power change and looking at the knock sensor readings.
He started tuning with a base tune that is considered very safe and so i do not know why this motor is so detonation prone, that is why i say that the car was a ticking time bomb look at the attached log, that was my last pull and the ecu pulled timing on it, i think that i may pull another deg or two out to make sure that it is ok on hot days, ill defently be runing some racing gas or E85 once i get the flex fuel sensor going and a tune on track days... and will start to build my spare motor LOL

I know how to get RPM signal on Fab9 COP, just needed to experiment a bit... the dyno operator should have been able to do the same with Toyota/GM COP system.

You can manually convert the MPH dyno plot to RPM on the bottom axis if you have your rear end ratio and what gear it was dyno'ed in, and from RPM and HP derive the torque. Sort of a pain in the ass but you can do it.

Can this be done with the "viewer" software or only with the full dyno package? You can download the reader for free. It's called WinPEP.

You'll have to do it manually. I don't think you should have to, though. We had rpm signal and torque numbers generated on your car.

I'm trying to comprehend how that's better than a 1.8
Or do you mean a n/a 1.8?

Good job dynoing your cars though, and 240 out of a t25 is pretty good for sure
