That dyno reads wicked low, lol.

Missed the elevation. That's not terrible, then.

Yep, probably lowest dyno anywhere. I ran 12.9's on my 279whp VF52 setup at 5860' track elevation, so 300whp on this dyno equals mid 12's at sea level.

is this the first tune that was done on the car? i'd be interested in seeing that boost graph before and after the ebc/16g...

 

The bottom overlay is the VF40 on stage2 vs the 16g tune. Remember that I'm a mile above sea level and numbers aren't going to look as good as those of you with nice dense air.

You also have to consider type of dyno, temp of day tested, correction factor, etc.

 

The 16g is still on stock fueling, you can't go much more than that. I've since added a PW intercooler and had Cryo tune it, don't have numbers for that yet.

i saw that graph, but was wondering if you have a boost vs. rpm graph at stage 2. just curious to see how the spool changed and how much better boost was sustained to redline.

 

anyway, you are running 10.5 afr, is that correct?

This isn't my current setup.

 

On this dyno I was <10.5 AFR, boost tapering to 15.5 psi, target of 17.5psi.

 

Currently I'm at 11.0 AFR, boost tapering to 17.5 I believe, target of 19.5psi. Haven't done a good dyno with that yet and I'm off my left foot again for another 3 weeks.

 

The 16g could easily hold more out to redline if we wanted to, we just saw declining results after 17.5psi on the upper end of the powerband that we felt weren't worth pushing it on since I had stock fueling.

 

Boost response followed the torque curve if you look at the overlay. I hit peak boost at nearly the same time as the VF40 did.

 

The VF40, IIRC, held something like a measly 10.5psi to redline.

 

Isn't Grand Junction at 4,500ft? Is that where you dyno'ed? I dyno'ed in Longmont at 6,600ft. That is a difference. What dyno did you dyno on and what was the correction factor? What was the temp of the day you did it?
