What 100 octane fuel are you using? did you try going higher than 22 deg timing?
Nice results indeed |

Awesome numbers. I don't remember seeing if you're still at elevation, but I think I remember seeing LMP getting some more power out of a 2650. I don't remember if it was on E', and of course, wouldn't know the cam' specs', but the boost was similar, and your numbers are still great.

My tuner believes it only wants 22 deg. at wot, which is very surprising to me considering that I believe that's pretty close to stock advance. Actually, it's more than surprising, it's ... confusing

Nice results!
Fwiw, Folks get way to worried about timing...my brother is the same way. 22 degrees is probably close for a setup like that. 24 would be absolute max imo. This isn't your average bolt-on or mild cam setup where guys are pushing 28-30degrees on Ethanol. Cylinder temps play a vital role in how you time an engine. Something making 1100+ vs 700 is going to have significantly higher cylinder temps. Aside from that it didn't hook before, so it sure as hell isn't going to hook now. So a degree or 2 of timing should be the least of concern here. lol

Negative. I run E50 at a very similar power level and run 22 degrees. More timing will just be hard on the bottom end for little power gain IMO.

I've got a can of MS109 and would like to make a few pulls on it to see what it makes on say 24 degrees versus the current 22. I agree with Josh that every degree of advance increasingly beats the crap out of rods and pistons. But this engine is rated to 1400, so...

That 1400hp is likely at the crank. At least that is how most companies rate engines. You are likely close to that now. At 17% drivetrain loss, 1400hp = 1162whp.

I looked into this crank to wheel horsepower loss topic last year and I ended up thinking it would be closer to 12 or 13%

What people often don't think about is tuners also have to take the owner into consideration. If it hurts the motor it is likely to always be called the "tuners fault." Does the owner read their plugs, log their car, do general maintenance? Things owners in the past would often do few nowadays have the know how to do themselves. Everyone wants the big hp with the stock reliability. That will never be a reality. Leaving a little bit of power out can leave a nice cushion for small mechanical issues. This is an observation and not aimed at anyone in particular.
I'm running the factory rods and crank in my C7Z that has been built for 10k miles now. It sees 24 degrees of timing by 3,400rpm and maxes out at 26. Engine runs like a top. Would I recommend it to someone that can't read data and turn a wrench? No. On the flip side the blower is still being ran in it's efficiency range where g/cyl still climb to the cams peak hp and running on DI only. A way many don't spend the money to do so. |
