Default 9 PSI how long will it last at 13:1?

I know I know its a loaded question but here's the scenario:

Alky Control and Wideband both apparently bit the dust at the same time, or at least very close to the same time. I hardly ever drive the car but I drove it 5 or 6 times and a few wide open throttle pulls and apparently the Meth wasn't working because the pump has gone bad on me. I got my new wideband installed and it has been running very lean through boost at 13:1.

Tomorrow I plan to pull plugs and do a leak down to make sure nothing is hurt, but the car is driving fine and on the scanner appears normal. Oil pressure looks fine too.

I am getting a new pump from Julio Monday as well.

Any other advice you guys got to get me back on track?

I got a pressure sensor from Julio a while back and wired it into my HpTuners module for data logging methanol pressure. This setup helped me see my pump was going bad about a year ago.

Good idea on monitoring the injection pressure. Any part numbers and or photos of said sensor?

I don't have any information on the sensor, but I got everything from Julio.

It will live a lot longer than people think. 13.00:1? Or like 13ish?

I think with the right tuning it most certainly could live awhile.

Depends on how aggressive the timing was set, no?

Leak tested it tonight with results ranging from 10% to 13%...

I am going to keep going through it, adding some Brian Tooley Racing Springs, new methanol pump, and new Vortech seals.

Feels good to turn wrenches again!

You could always throw a thicker headgasket on to chop the compression down some

It's fairly low, thick gasket and dish pistons

Haha wow. Sorry. Work + grad school is owning me. I was mixing this thread up with a different one.

Come on down, we will take something apart on yours!

I am anxious to check my setup height on the springs, I think its setup too tall and not providing enough seat pressure. Hopefully I will have the car back up and running in the next week or so. I am going to try and video changing the seals on the Vortech to show the guys on here how to save themselves a buck or two on the rebuild.
