Because of the boost drop from 6000-7000rpm effective boost was only 17psi vs 20psi everywhere else in the rpm. I'm going to dyno at like, 25psi.

A word about this timeslip.

The car on the left was my factory stock (other than intake which is supposedly proven to be worth 15hp) IS-F. It would probably put down about 350hp on a given dyno.

Soviet and I lined up a few times, and both of us were pretty consistent, him at 12.6-12.7, me at 13.1 or so. My best ET was 13.009. Best 60ft was 2.003 Each run, I think I would pull ahead by about 1 car, probably due to him having to shift 3 times to break 80mph. The IS-F shifts in .1 second and it helps a huge amount. Around 90mph, he would catch up and walk away.

When we have highway roll raced, it was the exact same thing. Around 90mph he would walk away faster and faster. Exact same thing also happened when I raced a cammed/I/H/E/flashed 400hp C5 Z06.

I stopped inviting you to **** after you blocked my phone number, even though I sincerely apologized. Shrug

There's something wrong with that Z06. I make that with factory LS6 heads and I whomped an I/E IS-F a year or so ago.

When we highway raced I was at like 22psi, but was on smaller 6258 turbo.

Started tuning closed loop boost. Surprisingly easy so far.
Set my boost duty target to 20psi and gawdamn. Wheelspin in 3rd is a given now. Had to tune boost in 4th.

This is vs my old 4th gear pull (18psi/open loop EBC). Key points:
  • 20psi @ 3650rpm
  • I still have another duty (Stock 99 fuel rail and NA regulator)
  • The boost dip is there but currently only P is set out of PID.
  • Closed loop EBC is working neatly - it attempts to compensate for boost dip but doesn't lower duty enough
  • I lifted before redline because **** me it's fast and I don't want to go to jail
  • Exhaust is still hitting things, making my knock sensor like 4x amplified. The exhaust literally acts as a giant amplifier.

Spools pretty darn quick! Noticable spool difference from the 6258?

Well.
It feels a little a tiny bit laggier but logs show, at most, a 300rpm difference in spool. Then again I feel like I got used to this much power so whole car didn't feel "as fast" until about 20psi. Yes, I'm complaining that 300whp miata is slow

It's still amazing and I like the 6758 more.

doesnt look like its tuned yet. you might be making more boost, but the PID isn't tuned to where it's manipulating the boost output...it's following the same curve as before.

Pretty interesting (to me) that both cars are picking up about 25 MPH on the back half even though Soviet's car is faster on the first half.

Yeah I know. But already it's better than before (lol open loop).
It's trying to manipulate boost - boost duty changes (a bit) with response to boost dips. This was with just P=5 and rest of values set to 0.

Miata has 80s aerodynamics? I was rocking the hardtop btw. I also shifted from 4 to 5th in the back half

He's pretty skinny for his height. I had shorter fatter people not fit in.
