First, please understand that these new results are *not* load tuned. I pulled timing in higher boost back 5° and 3° back in mid boost across the table. Even though the results are lower, the car runs much better than before and does not feel any slower to me at all.

Here's how she pulled yesterday at the MS meet at DIY (same dyno as before). This is with the same setup I've been running for a while, spark fired through Toyo Cops, plugs at stock .045" gap.

236whp / 220wtq--waiting on DIY to email me the graphs




Can you say boost control issues?



Now, remember above when I said the car doesn't feel slower than before? Below is a cap from a pull on the street. Notice how much higher and sooner full spool is. Also note how much better it's held. I bet there's at least the 20 whp that can't be accounted for on the dyno. And this is with spark peeled back.

ben do you have a datalog of boost duty cycle?

Ben

No, unfortunaltey with the new code I'm running there's a hoop to jump through before I can log boost duty cycle. Which I just haven't done. But I have no reason to believe that it's anything other than what I've laid into the boost duty table posted.

Ben, why does your car sit at ~1500 rpm for a while after you floor it? dyno?

Ben

It's the load dyno. I don't think the ramp rate and run time used were correct. Which also explains why my MAP curve looks entirely different on the street than on the dyno.

I'm probably going to be running on a dynodynamics later this week, just for a comparison. I met the owner of a semi-local shop with one, and he said I could come and take pulls for free when I wanted.

Real good stuff Ben, wish I could've attended the MS meet!

So basically your EBC table is showing that the WGA has to pretty much keep the WG shut to hold boost to redline? Are you still on the original actuator?

Ben

I think what's happening is the WG doesn't shut. I've got an actuator from a 16G to replace it with. One day, maybe, I will. Also considering installing my webcam 505s.

Here's my plot from Saturday. Compare the tq curve to the falling boost curve.

Like with Atl93's run, the dyno wasn't set up right. I can't imagine how it's not putting down at least 260 with the way it drives.

If I may ask for some clarification here, if your motor is able to handle the 15 psi that it shows you climb to, why would you need a built motor in order to handle holding that 15 psi to redline? Is a given pressure harder on the motor the higher the rpms?
Thanks I just like to keep learning.

a freind of mine used the magnaflow kit and it had good results. I belive it was the 2.5 inch 'non turbo' design

Curious about this as well..
