I did some brief searching and couldn't really find much, anyone know what the record is for a BP with a stock MSM turbo strapped to it? And by stock I mean truly stock turbo, none of the upgraded ones. I'm curious to see what it is because I love the response and oem packaging of my setup and plan to improve on it this winter with rods and upgrades on both the intake and exhaust side and see what it will do with a little more boost and some timing added back in, seeing as we had to detune for the sake of the rods.

14psi is about the most boost you'll run on the stock turbo and even then it's pushing it, that's when the OEM manifold tends to crack and you're just pushing hot air.
210-220rwhp is around the max with the usual bolt-ons, injector upgrades and aftermarket ECU.
You don't need to upgrade your rods and pistons - you will need an aftermarket ECU since the stock ECU is crap (dead-spot between 4000 and 4500 rpm where you'll be running lean until it kicks into open-loop mode; beyond 140rwkw the OEM ECU just can't cope and your car will run "rough as guts").

I'm honestly still kinda stumped over those timing numbers to be honest.
You guys sync'd the timing correctly right? Or maybe throwing a cas on the newer bp might throw things off?
I mean that's less than "locked timing", which supposedly melts stuff from being so retared.
I've seen 4* run in the midrange on a 400+ bp running a 35r snail at 25+psi, which made sense to me, but this just doesn't add up.

Ill let Josh answer the timing question, however I can say that the CAS has been deleted and the car is now using the MSM cam and crank sensors. I think that at 14psi, with a proper 3 inch exhaust with a wastegate dump and a tune that actually has a bit of timing in it, I should have no issues clearing 250whp if not more.

Yes sync'd with a timing light and yes, CAS. It's now CKP and CMP from the MSM and on a MS2PNP, but we haven't dyno'd it yet, rebuilding with forged rods first.
Timing was set to fixed 10, pulley was set to read 10*. The only thing I can think of would be if we looked at the wrong mark, but that would back fire like crazy and be technically -6 degrees instead of 4, correct? Or would that be 14*?

Back to the question of possible wrong mark used. If the wrong mark is set at 10*BTDC, then the correct mark would be at 20*BTDC. So, if you did that, then indeed, you were running 10* more than you (and your MS1) thought.

The timing thing might be legit after all.
I keep digging for more info, and here's another example of relatively low timing and similar torque/power. Though this guy is on e85
Zwoollen's build thread
230/250 on 12psi within 2 degrees through the range overall

Well, I wouldn't actually. I hate the NB dual mark thing.
But if you're referring to our pitiful timing table, we were either accurate and super conservative, or we were spot on for a safe turbo setup.
My 1.6 and a small T25 was at 20* near redline.
The MSM engine was at 6 or 16*. Either way, still conservative.
