9/20 Dyno results
Well, alot happend this evening on the dyno. Tested alot of things, JWT ECU at high boost, Stock ECU at low boost, cut out open, cut out closed. Got alot of the runs on video, including the few runs where my feed pipe blew off. Thought my motor blew the noise was so lound, scared the crap out of me.
Still need to get the run files e-mailed to me. Did have them print out my favorite pull of the day though. Stock ECU at 8psi. Will probably post the other results when I get the graphs to post. Hopefully Steve can get the video uploaded for you guys. Thanks to Steve for comming out and good luck tomorrow on the dyno, sorry I took so much time.
330whp 332wtq @ 8.0 psi
Lets just say that I will be running the stock ECU from now on. I am getting 21whp per lb of boost
. On the dyno I could only get 8 psi out of my 10 psi spring (boost controller turned off) since the load of a dynojet is much less than the street. On the way home I was getting 10-10.5 psi out of the 10psi spring. That puts me right around 370whp 370wtq.
I get detonation and what seems to be spark blow out when I hit 10 or more psi on the stock ECU. Will have to put the .4 bar wastegate spring in and use the boost contoller to get me to 9psi. Should be safe there and should put me right at 350whp. Honestly, car is very sick at 10psi and the stock ECU, Tires are spinning like crazy into 3rd.
Mods for this run
Garrett T4O4e 46 trim, .60 exhaust side and .70 compressor side
2.5" to 3" feed pipe
3" down pipe
3" cut out
MEVI
Z32 MAF
550 DeatshWerks injectors

Don't count in the JWT ecu.

I have not kept an exact tab, but w/o the JWT....right around $6K or so.

Yep, that was the best run. I don't really want to get into the whole JWT ECU thing right now, but it was not good.

What spark plug and how much you gap it?
What spark plug and how much you gap it? NGK one step colder at .036 gap. Will try 2 step colder or just gap my current ones to .032 or so. I may be fine at 9 psi, don't really know what was going on but at a little bit over 10psi things were breaking up at round 6K rpm's. Once I get the boost down a bit I will see how it feels. Closing the cut out will probably do the trick and put me at 8-9 psi.
Going out of town for the next few days so I will follow up later with the other JWT runs.

Mike, whats your email addy? Am I supposed to pick your files tomorrow.
I will edit the video Thursday and try and get someone to host it while you are away.
I would try the 2 step colder and close the gap on those a little. there is no harm in running more psi. What do you think is causing the detonation? Timing?
Should have filled up with race gas like me

Nice numbers! I feel your pain on the detonation front. Thats the main reason I chunked the SAFC II and got the Emanage. I still have it past 3/4 throddle but school and work have kept me from strapping it back down to get it squared way.

i had the same problem with detonation at 10psi on the stock ecu. i was told it was the stock timing so i keep it @8.5 psi. as far spark breakup i got a BAS
oh and great #'s i only got 314whp 343tq @10psi.......
kind of jelous

Man Congrats Mike 
, It seems that all the turbo I30's are around the same hp and tq for right now 
. I made 330hp and 350tq at 8.5psi. Mike you should get the EU cuz once they come out with the new update you should be able to take care of your detonation also get the BAS I know pawnstar has it and i also have it. IT works great.
Can't wait to see the vids.

As of now I just plan to not run 10psi. I had the cut out closed today and saw .6 bar and that is safe. I may have to put the .4 bar wastegate spring in and adjust boost from there because with the cut out open and my .7 bar spring I see noting less than .7 bar. But that is not a good solution because boost will vary depending on which gear I am in. If I set the boost controller for 9spi in 3rd gear I can very well see 10psi in 4th. Not sure what I am gonna do for the long run. I would be content at 9psi but it is just not smart to have to worry about spiking to 10psi all the time.

So are you saying the stock ECU can handle the Z32 MAF and 555 injector w/o any problem,if I use the Emanage to reduce the fuel down,can I run like 10 psi w/o retard timing on the stock ecu?I rather have the stocker than the JWT ECU,so no problem with start up and CELL.Thanx Stephen.

Pulling more fuel with SAFC means adding timing which is bad. He can't do that he's already walking a dangerous line with stock timing as it is probably.

Neal, I think he meant pulling the fuel with the afpr and not the safc. Didn't Mike want to do that anyway? I was thinking of dropping about 2-4 psi of fuel pressure myself to use a little less safc correction. I currently am anywhere from -12 to -16% correction.
