Default Just returned from the dyno...

I'm not about peak numbers so here is a real world, on any given day, on pump fuel dyno chart of my car.
3 runs at different boost levels. 15, 16, and 18 pounds respectively...

Drives great! Turbo is a Turbonetics 60-1 HiFi. AFR is a bit deceptive...they just stuck an O2 sensor inside the end of my car's tailpipe...

The closer to 14.7 the leaner it is.

Pretty good numbers though. I am expecting to see similar with my 60-1 HiFi also. Looks like the powerdelivery isnt much later than my K26/6. In comparing the charts i get 200ft-lbs about 200rpm sooner, however 200hp comes on at roughly the same point. Any idea when you are getting 15psi by in 3rd or 4th?

And these are with a cat in place!

21 psi? Don't want to break anything...like I said, real world numbers. Just becuase you can run 500hp peak for a few seconds does not mean that is what you're running while cruising around town every day.

Sam, haven't had a chance to really see on board numbers. I received the injectors I needed today, slapped them in, and headed to the dyno.

Nice numbers but it's pretty lean. Knock it down a full point.

So, what did you change since your last dyno runs where you thought your numbers were low? or did you just rev it higher?

I think you are thinking of Josh. I haven't been to the dyno in a while.
