Ok well JZT130 hit the Ron Hill dyno dynamics dyno today. It went a bit like this. First power run made 210rwkw but as suspected the external wastegate wasn't opening. At this point I checked the datalog on the wolf and it had max boost of 23psi! I was a bit scared of this as I don't want anything to blow up again.

I had already checked with 3 or 4 knowledgeable people regarding the setup of my boost controller with external wastegate. I had the bleed line going to bottom of wastegate and the pressure blocking line going to the top of the wastegate. (this is supposed to bring boost on quicker). So I tried some other ways of installing the boost controller and each time it would go to 23psi of boost and then miss badly so the throttle was let off. (spark plugs are gapped to .8mm) So I was just about convinced that the wastegate was stuffed and wouldn't open and I installed the boostcontroller in the opposite fashion to what I was told to do. Guess what? Holding 12psi now??? The bleed line is connected to the top of the wastegate and the bottom of wastegate is not connected at all. Anyway this worked so we did a couple more runs, the temp was starting to get up there so we had to wait a bit between runs. Water temp was about 95 and intake temps were about 50+deg.

So I was running 12psi boost and it made 182rwkw. Then I wanted a little more boost so I turned the valve and it then made 20psi again! Now what was shocking to me was that it only made 192rwkw. Don't think about the total number just the difference. 10rwkw for an extra 8psi? That to me is saying that the turbo is way out of its efficiency range or the entire engine was bloody hot. (which it was)

Either way I am pretty happy with the results. it is tuned to 7500rpm now and feels great. Boost comes on hard at about 4000rpm.

Also this was not done in shootout mode, they aren't accredited shootout guys. The dyno was done in second gear on the auto so it didn't kick down.

And to put that into perspective, the tuner had his track car there which is an sr20vet powered silvia with wolf 3d, extractors, exhaust, CAI and MSD ignition and it made 84rwkw. This engine stock makes around 140kw IIRC. Can't find any info on it? And a 4age 100kw sprinter with exhaust, manual box made 57rwkw.

So I am pretty happy except my bloody A/F ratio datalogger wouldn't work so I couldn't test it. I am going to get this working and then finish tuning the car myself as it is still running around 10.6:1 at 7500rpm.

It will be interesting to see how this power figure relates to the quarter mile when I go there in 2 weeks Smile

Will have dyno sheet up soon. POS camera not working Sad
