No breakthroughs today. My best 2 passes were a 9.0@152 and a 9.0@151. I was having lots of issues launching the car. I ended up having the boost controller setup back asswards for the first 3 passes and the power was coming in way too fast. It's kind of confusing how these AMS's work. Ramp rates hose me up because you don't define the amount of time in which you want to hit XX psi on the gate. Instead, you give it a target and then you have to select thru a bunch of predefined rates. Once I got my head around that, I started having an issue with bleeding off boost. Not sure if I cracked the FAST, or if somehow a burnt wire can cause a misfire that would cause the BOV to crack open and bleed off the boost. Went to go make one more pass to see if I could duplicate the problem and noticed that my oil pressure was down about 6 psi from what I'm used to seeing at idle. Usually I get about 35 psi hot idle and was seeing 28-29 so I called it a day. Not real happy about the day in general but **** happens.
Tomorrow I'll check the plugs and wires and just start with the basics. If that doesn't resolve it, I'll pull the intake and see if it's cracked.

Don't get me wrong, I made my share of mistakes. Instead of buying the 160# injectors with the driver box or a good set of high imp injectors, I bought a set of 80#'s first go around. That was a net loss of $150. I also bought 2 wrong wastegates with a total net loss of $400 trying to save money. Those are just the 2 things that I can think of off the top of my head. Not to mention all the thousands of dollars that I wasted screwing around with strokers and nitrous before this.
Do it once. Do it right. Cost me WAY more than that over the years I'd think. In my first turbo build now. I set my goal and am getting supporting mods that should handle a little higher.
What options are there for great set of high impedence injectors for 1000-1300 rwhp? Or would someone be better off going with 160s from the start? Needing a 410 ci motor to idle around, off boost. I plan to have a boost referenced regulator. #1 priority being to not run out of fuel or run the injectors too hard at WOT, cost is farther back on priority list.

I just started using the ams on my car as well. Are you just using one stage? I dont know what you mean "predifined rates", they are all in psi per second and you can adjust it to the tenth of a pound. If you need it to come in differently you can use multiple stages.

For instances, let's just say that I want to put 10 psi on the gate for launch. Then I want to ramp up to 40 psi on the gate over 5 seconds. I have to set Stage 1 to 10 psi (simple enough) and stage 2 to 40 psi. No problem. With the controllers that I am used to using, like for nitrous, you just tell it over how many seconds you want it to take to get from 10 to 40 psi. With the AMS I have to do the following math:
40 (stage 2)-10 (stage 1)= 30 (difference)/5 (seconds)= 6 psi per second (ramp rate)
With the AMS1000 it's more confusing because you start throwing in more stages and delays.

Motor's gotta come out. Lost about 5-8 psi of hot oil pressure. Pulled the filter and cut it open. Oil has a gold sheen. Should be a simple bearing swap. Car's not making any noise or anything.
Anyway, this is the second to the last pass before I noticed the problem. I lost the wire on the next pass and boost surging started. That's when I started checking stuff and noticed a couple gold specks on the dipstick.
This would have been an 8 if I hadn't kissed the limiter in first into a 15 MPH head wind.

Thanks. Jegster Adj tunnel mount adj torque arm, Jegster adj LCA's, Spohn Drag Bar, LCA relocation brackets, Comp Engineering 3 way shocks, Eibach springs and a S60 rear round out the back. The front are QA1-R single adj shocks and 275 springs. Stock control arms.
If you you close you can see my rear lifting as I take off. That's because I twisted the splines in the driveshaft yoke which had my rear suspension in a bind. That's on the list. I'm going to have to break down and buy a billet one. I'm on my 4th or 5th slip yoke.

I have since switched over to the Bosch 160# Low Imp Inj with the AEM Driver box and am running E85. I'm around 72-74% now on E85 at about the same power level.
Here are some shots from the track rental a couple weeks back.

Where did you hook the turbo oil feed line too?
What fuel rails are you running currently?
where in your oil pan did you weld in the AN fitting for the oil return? Do you have any pictures of this?
What does your PCV system look like on your current motor?
I have a 99 Z28 so do you think I should be good to go with the 99 ECM as far as tuning? My goals are low 9's or maybe a 8.9X like you ran
I read all pages of both threads and I didn't really see anything about these topics so thought I would ask. Thanks man. Again, basass build!! You are my inspiration. LOL

1) Just above the oil filter on the side of the block there is a little plate with a hole that is halfway drilled thru. Pop it off, drill it and tap it.
2) I honestly don't remember where I got the fuel rails. Most likely Speed Inc. Just make sure to find out what threads are on the end so that you can get the correct fitting for it. I've seen some that are done in standard AN and others that are shallow and require an oring fitting.
3) Oil return is going into the driver's side of the pan towards the top. Use atleast a -10 , -12 if you can get it to work.
4) PCV system is really basic. I have a pipe welded to the back of the driver's side cover and I had the front fill neck on the passenger side modified then it goes to a catch can.
5) 99 PCM should work fine. You'll need to flash it with a custom OS, get a 3 bar MAP and a tune.
