416 LS3 TFS Dyno Results
Was so happy to get my car back, thought I would post up. Have a few loose ends to tie up, but for now:
536rwhp/497rwtq. ~12.5 A/F, 103F, 23 deg total spark. Graph to follow when I get it.
Once the engine is broken in properly, we plan to try and squeeze more power with race gas and agressive spark. Until then, I must say the cam characteristics really made my day. I ended up with max power around 6200 only giving up 4rwhp at 6600rpm. Once its ON, its ON and stays there. I like that.
I'll be making a few test-n-tune passes on Fri to correlate the data.

good job...but whats with you and your weak *** timing tables...thought I convinced you to crank it up...if it doesnt make more power back it down...unless you tried and got KR....sounds strong though...did you get your oil consumption issue worked out?

This combo is going to get pushed. Oh yeah, the oil consumption according to him is the engine is not broken in because I didn't drive it very hard until we hit the dyno. That was the first time it saw high rpm. After I drove it home, it seemed to run really well. I will be checking the plugs and oil consumption as I go. Getting a high volume oil pump Fri.
247/254-113+2, Comp Cams LSL, 6100rpm. The HP pretty much stays the same from 6000 up, losing 4hp at 6600rpm where we let off. Guy didn't send me the graph today, but will post up tommorrow.

That cam looks familiar for some reason. I think we should call it the PRAY cam. Seems to be pretty popular right now. Great results. Give it some time and it will come around. I would add more timing as well. 23* is leaving stuff on the table.

engine's performance, but I chose the 113 to experiment with better cylinder pressure on top. Would be interesting to hear from cam guys on this. Those heads flow so well, I was beginning to wonder if the exhaust scavenged them so much at high rpm, that more mix was leaving via scavenging than getting burned. On both my 346/TFS and 402/TFS setups, I had 112s and in both cases the high RPM died off quicker than I thought it should. Kurt's 346 ran so well on the 113+2 (as did my old 346 in my 03Z), I thought why not combine the two and see what happens.
I'm going out tonight, taking a few degrees of spark off the table and see what happens.

416 drag passes update...
11.1@128. looks like my skilz are little rusty. I got to make 3 passes. 12.2, 11.4, 11.1, then decided to leave. runs were on drag radials, pump gas. I wanted to test a lot of spark and thinner fuel mix but no race gas at the track.
Seems this engine burns more oil than the one I replaced. WTF. Engine has 1072 miles, probably has used about 3 or more qts oil.

Good first outing especially on drag radials (which ones?). Hows that RPS feel and launch at the track? What gears? did she feel better with more timing? Hope that oil usage gets better with miles

The RPS clutch is nothing less than exceptional as a performance clutch.
The clutch worked exceptionally well, takes slipping, hp, whatever I could throw at it. This engine will probably get fired first of next year. It is what it is, an oil burner.
The guy who did it may be a sharp machinist, but his skill with LSX = FAILURE. I don't want to mention his name at this time.
