Went to the Dyno Jet this afternoon

I've added a vid to the first page.

Love how it sounds.... And funny side note, when you turned the camera to the left, my brain thought your car was launching off the rollers if only for a split second. I felt like a highly functional retard.

Haha! Did you notice the puff of vapor come out of the filter at lift off? I've seen that happen on other dyno vids but never seen one my cars do it.

Good numbers, but if those dyno widebands are even close (within .5-1 AFR), you've all got issues that need to be addressed...8:1 AFR is NOT good, even for a FI engine. Should be 10.5-11.5:1 depending on the setup, Id imagine on a stock internals/turbo 1.4 that closer to 11.5:1.

MPFab, good TQ numbers! Notice that your peak TQ comes right around 11.5:1 then drops off quickly as your AFR gets richer...lean it out and you'll make more TQ all the way out.

Preloader, need to get your tune changed again, waaaay too rich there. Leaving power on the table and dumping fuel unnecessarily.

That dyno was from a less than optimal tune, but it's e85.

So 8:1 isn't ridiculous. 9.5:1 is ideal.

Scarab, Preloader's graph was on E-85 and the WB numbers were adjusted for it. That's why you are seeing 8s. My car makes peak torque at 12.5:1 AFR. It honestly needs to be 11.5:1. It would possibly make more torque, and would definitely be safer. The tune needs a few tweaks, but it's pretty darn good out of the box!
Torque drops off because the turbo is the size of a thimble No amount of changing fuel is gonna overcome that!

I believe Pre's current plan is to replace his thimble with a shot glass.

you mean a bowl?

So you're saying that the dyno WBO2 was setup as stoich=gas but he's running E85? Easier to compare with Lambda/EQR for this reason!

I know the turbo falls off, they pull pretty well from 2500-4500ish then fall off.
