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.

Very very nice man Congrats...
With a better wheather ,little leaner A/F Ratio and more mileage 550rwhp shouldnt be a problem.

Any sounds clip?? your running pump gas??

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?

What lsa and at what rpm did you make peak HP?

That should definitely be fun in that Z06.

Nice numbers! Really leaning towards those TFS 235's look like they really putting some good numbers.

Great combo thats got more left in it!!

The dyno tuner would not do it. Was all worried about the engine. I even tried and pushed hit to lean it and add spark. That will be tested trust me.
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.

The 235's are bad ***. I had a set on my 414 and it made 558rwhp 515rwtq n/a with a 244/248 cam. cant wait till i see what they will do on my new tt set up

awsome numbers

Very nice man. Like Kurtomac said, once you add the timing she probably wants, you'll find more power. Good luck at Test N tune.

why arent YOU tuning it on the dyno...just have a dyno operator nearby...why the high voluum pump? experiencing oil pressure issues?

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.

I am going to be tuning it tonight and tommorrow. Oil pressure was 28psi at idle. I didn't like that and even after throttle up I thought it should be higher, 10psi per 1000rpm. Now the pressure problem is gone. I'm surprised you didn't lose some oil pressure w/your aftermarket cam. Remember, aftermarket crank/cam/rod bearing clearances are not the same as stock and oil pressure can vary. I think the LS3 block also has larger capacity oil passages. (rumor, don't know this for a fact)

The @0.050 specs and lobe were definitely chosen based on your
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.

Lmao. yes it should cause i have the same one but on a 112+4.
congrats on the new numbers post the graph when you get a chance.

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

Low 11's not bad!

Who built your motor? Shouldn't be going through that much oil. Did you floor it at all the first 10 miles to seat the rings?

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.

I drove it spirited but did not hammer it. In restrospect I can see it makes no difference. I've never met an aftermarket LSX engine that was not an oil burner. That engine block must be very sensitive to honing, boring, etc.
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.

what drag radials and gears were you running...try HKE if you build a new shortblock
