Well, VR-4Maniac brought me 15 gallons of 103 unleaded today (VP Streetblaze). We dumped 10 gallons in along with the 2 or 3 gallons I still had in the tank.

On 93 pump, I used to get knock at 11psi (20+ counts). With VP103, no knock at 11 psi. No knock at 14psi. 16.5psi showed knock counts of 5 around 6500 rpms in 3rd gear. Richened up the arc2 a click and knock disappeared down to 0-1 counts throughout the entire run at 16.5psi.

We didn't turn boost up anymore, although I think it's possible I could run it up to 18-20psi without getting knock. Timing is advanced about 6 or so degrees too overall (9 degrees base timing, plus 2 degrees advance built in to my ecu upgrade).

Car pulls very strong past 4k rpms. Up until then, I have lag that makes me miss my 9b's, lol. Whoever said TD04's don't have lag is full of it because I can definitely tell the difference between these DR650s and 9bs. But, it's a worthwhile tradeoff. The speedo climbs very fast from 70-125mph in 3rd gear. This setup pulls an ungodly amount harder after 4k than my 9bs ever did. I think VR4-Maniac enjoyed the ride too. Within the next day or so, I think I'll try 18 or 20psi and see what it does.

Now I just have to fix my stupid high idle issue. Will continue working on that one tomorrow. Gonna try the IAC tomorrow, and also a tip about my krankvent that G-Ell gave me.

Don't forget to log warm idle IAC counts.

Whining about turbo lag... I told you to go with DR500's.

Warm idle IAC counts should be at around 10 or so. Also, if you rock the wheel back and for the IAC counts should change. Lastly, make sure the idle switch is turning on/off using the diagnostic menu on the logger.

I am jealous....its going to be a year yet before I get my heads/turbos.

I was really thinking about going DR500's (even though I'm almost positive they'll be too small for me) since Matt M. will supposedly upgrade you to the 650's for the difference if you are unhappy.

I'd like to see what the 500's could do with all the drive line mods I have along with the MAP ECU and some good tires, say S03's perhaps?

I was just thinking about this Jesse and remembered you're running that goofy HKS (overly complicated/supposed to learn your boost curve) boost controler. Have you retuned it since you got your motor back together?

With the way your cam gears are setup, you should have significantly better spoolup with those turbos compared to guys running the same turbo without cam gears.

I still have the EBC set the way it was. The only thing the learn process does that I'm aware of is determine wastegate boost level. Still, I'll probably recallibrate it this week if the car ever sees the outside of my garage again.

Read that thread on 3SI about my dr650 review. According to Matt, that's not the case.

Ah I see. Top end power is increased, but the torque is skewed. So, you may still have boost, but you don't feel it until above 4 grand.

Just wanted to make that clear.
