Alright, so yesterday I went to Ivey to get my car dialed in better on the dyno. Took about 2 hours since the base cal file he sent me previously was pretty close to what it should have been. I did about 8 runs total I'd say with cool downs in between and only had a few problems with the car that I discovered. The first one was a weird one--at the end of a pull, something shredded blew out of my engine bay and all over the shop. At first we thought it was the stickers on the Hoosiers still finally coming off, but it looked more like a paper towel. That was stuck onto my dipstick and block then even with me trying to scrape it off with whatever I could find laying around that'd reach. The next run the car was making hardly any boost at all. I found out that the lower IC pipe coupler blew off, so perhaps that's where the paper towel came from--stuck in the end tank of the IC and then popped out when the coupler blew. Ooopsy. :-\ The last problem I ran into was my alternator belt starting to shred ribs off of it. Prior to this, the alternator was hitting the frame with the bracket I made so I had to modify it some this past Sunday but it looks like I took too much material off and moved it in too far now. I'm calling up JayRacing later today to order one of his as I'm done trying to rig this Buschur-makeshift relocation bracket I made.

So onto the numbers, I was on straight 93 octane Exxon gas I picked up earlier yesterday, no Meth/Alcohol/Etc injection--just pump gas. Had the car set at 23psi and settled out with 465hp/358tq at the end of the session. We couldn't add any more timing or lean it out as it was starting to knock in the upper RPM's then. A/F was in the low 11's

One or two pics from yesterday:

Things left to do:
-Wet sand and buff the hood as Frank didn't quite finish mine all the way. I suppose that's why my price was slightly less than it should have been. Also, the hood's fitment is a little shorter up front than my last one for some reason so I need to mess with the hinges or something else to pull it forward and cover the lights/grill more.
-Clutch pedal install, which I'll probably do tonight
-Alternator alignment fix (again)

And that's about it. I should be at the shootout with it. Maybe it'll still be on pump gas, maybe I'll put a little race gas in it and up the boost 5-7psi. I don't know yet. :)
 
Was the Knock sensor calibrated?
 
usually what I do is make an initial pass at low boost and record Knock sensor noise and build a the knock map from that. I'm sure with things relocated and remounted in different areas of your car, your engine nose has changed quite a bit since the older cal file.
 
Man that is one great dsm build.I just spent the last 30 mins reading all 7 pages, and dont feel like I wasted my life. This is one bad ass car man.The time and money spent on your build really do show in the finished product.
Good work man

Looks good Brent, wanna toss out any estimated times?
Nope, that'll jinx me. If any guess, I'll be running Supra times-- 12.xx @ 130+ :D

I decided on not trying to fix my alternator bracket issue and put in an order for a Jay Racing kit today so that should be here tomorrow. Other than that, I can only see my suspension not being set up causing some see-sawing on my launches (if I still remember how). Getting the thing rolling on the dyno yesterday was such a bitch without any give in the clutch discs like you'd have with ACT's or stock.

I need to upgrade my fuel setup first, then we'll see about larger #'s. If I wasn't going to the shootout, I'd have about 1/3 of the cash right there.
 
Brent, just curious as to where your RPM band did you get your max numbers at? Also, what kind of RPMs will you be shifting at?

I just took a picture of the dyno graph so here it is to check out and see anything else you're looking for. I'm not sure what that a/f dip around 5k is or why it was still around but I'll pull up the current cal file tomorrow and see if I can spot the problem.

I was only running up to 8k on the dyno but will probably be taking it to at LEAST 8500 initially. That'll give me some leeway if I 2-3-2 again. :eek: I don't know how far the power will fall off between shifts so I may end up taking it higher right away instead, although that also depends on knock or if I have issues getting into gear that high.

As for the rest of the car, the clutch pedal assembly is now installed and my dash and the rest of the interior is back in. That's the first and last pedal assembly I want to do again although it may be a hair easier w/o the cage in my way getting in and out. :rolleyes:

I also received the Jay Racing alternator kit today and that install went really quick especially since my alternator was already in the back. While taking my make shift bracket out, I discovered that the bracket was cracked and bent forward/inward causing the alternator to be misaligned. I can see there were multiple factors involved with why it cracked, but I'm happy to have something more durable instead.

The hood is on, I oblonged the hinge holes some, moved my front lights back some, and I think it's the best I can get them without making something else look out of place. All that's left is to wetsand and buff that tomorrow if I can, and swap out one or two interior pieces for nicer/cleaner parts. I think it's ready for a trip out to Ohio then. :)

Nah, no time to tune on race gas. If anything, I can put in 100 octane and bump it up about 3psi and keep the same tune Sean said. I'll be at the track Friday for sure though since we may have a little rain Sunday.

Last summer while the car was down, my old boss Nate (from DSMotorsport) was planning on rebuilding his car and wanted to buy them off of me rather than let them sit outside and dryrot. He offered me a pretty fair price for the tires and I let him "rent" my Kosei's then too for the summer so he didn't need to unmount and remount them on another set of his rims. I don't think he ended up using them much, if at all, and then he ended up selling them to TurboTrix's Bean's younger brother.
