Knowing how quick you are Shawn I'm thinking this is moot, but I had a similar experience with a custom exhaust on an old Datsun. Trying to weld it off the car had the guy taking it off again and putting it on a bunch of times. I suggested doing it on the car and it went a lot smoother. Also, I bought a used custom exhaust from Lart quite a while ago which was welded on his car. I couldn't believe how perfectly everything lined up when I put it on my car.

Been doing a lot of research wrt timing. Here is my first cut E85 timing map for Thursdays dyno. I will probably push it a bit more later. Spark plug gap will be 0.025". Any input appreciated.

Any numbers you're chasing Shawn?
For fun i'm guessing you're going to make 450 rwhp @ 18 psi at around 5900 rpm. Peak torque ~ 3500 rpm. Probably earlier.
For 25psi on e85, 520rwhp, probably more

Here are the goals I am chasing, they are from the original post:
I have some new goals for the build:
- 550 rwhp/500+ ftlbs torque at 6300rpm, E85, 20-22psi
- 1 bar at 3200rpm bottom end performance
- Total cost for changes under $3260 for everything including new turbo

Do you have a list of all the things you've done?

I've got a few questions. As this could possibly be the next thing to the engine I do in the hunt for more power.
Being still under square, how much could this setup rev to under the reliability circumstances? Or will a dry sump still be needed to properly achieve 7500 rpm?
The only thing holding me up from reving past 6800 rpm is IICR the bearings and the overall weight of the internals. Oiling i think?

That's a good question. I don't think it is, but then I also haven't tried adjusting the column headings either.
Might be interesting to see if you can (or a possible feature/enhancement request for Rogue if you can't...) for those who have no intention of running 28psi, get a little more resolution into tuning for lower boost levels.

I gather from that table that you have not quite identified at what RPM peak torque occurs since you increase timing pretty much proportionally with RPM there. Still these values seem a bit extreme to me, even with E85. You may get huge levels of cylinder pressure.
Could you post a log showing boost vs rpm?
