ok car scares me now.
did same thing tonight. raised boost, tuned boost control a bit, did some pulls
did same thing tonight. raised boost, tuned boost control a bit, did some pulls
- somewhere around 260-280kpa I can spin 4th gear. sure it's quite cold outside but GODDAMN
- 5th gear I hit... wait for it.... 275kpa at 3500rpm. That's 25psi @ 3500rpm.
- let me repeat that. 25psi @ 3500rpm
- I was going to raise boost to 270kpa but stopped at 260 because, really, I'm scared
- Pistons are still in block, no holes appeared
- There is still a small dip in boost but the difference now is less than 2psi between high and low.

Really don't think I'll need that much boost. I just need to keep the TQ going to redline. I already made 290ft/lbs last time but it dropped off. If I can keep it going, power will be ez. This time I have a bigger turbo, more boost, better timing control, better coils and a better timing map. I'll also tune my fuel to make sure it doesn't go rich in load like it did last time.
Borg Warner says turbo is good for 490 crank hp.
Scott sure we can film it

Tuned up to 270kpa (24psi) - holds it to redline. Weather is cold so I have no grip - meaning wheel spin in 4th reliably happens now.
Fuel is good. Boost is good. I hope boost control works same on dyno as it does on street (i.e. that I don't have to **** with PID on dyno).
Timing is good (11-12* @ 270kpa where peak TQ should be). If I'm really not happy with dyno result, I'll bump timing up 2*.
Max fuel duty cycle is 82%. Go stock fuel rail go!!!! lol. Knock looks fine. Spark is fine (no misfires). Crank pulley hasn't sheared yet.
Dyno in 7-8 hours!!
