New log on 50 trim @ 18psi-tell me how it looks

[FASTSPOOLINGST]

Did this pull this morning, it felt the best out of all the tuning i did, so i'm posting these numbers. For some reason, it will pull strong all through third gear, then i shift and when i start to hit the gas in fourth-it started bucking. I later did a 4th gear pull and it pulled strong without hesitation, it's like it only happens when i shift from 3rd to 4th and try to keep accelerating. Anyways, here is the log. Give me your perspectives and opinions on what direction I need to go in with my tuning. Any advice is welcome.

well, I got back to my house, re-shot my timing and checked my fuel pressure. I think the problem with the cut out was that my fuel pressure was set at 43psi w/ the line off. I dropped the bi*** back down to 38psi where it was supposed to be. Shot the timing, it was at about 10* base. I turned it back to base 5*. Cranked the boost up to 19psi now. Did a 3rd gear pull and holy crap, 0 knock- and hauled ass through third and fourth gear with no studdering.

I turned my boost controller up 1.5 turns, so i should be sitting at about 20-21psi now. This morning I'm gonna go do some more pulls and see what numbers i get.

I was gonna say, that looks like a lot of timing. It must pull like an SOB.

I know this is a bit OT. But i noticed you were still on stock internals! How long has that been holding up, how many miles? I've seen quite a bit of 1g's running stock internals with huge setups like the 50trim that you have. Of course your 6 bolt and im 7 bolt so im not sure how much thats gonna come into factor. But none the less, good log. Glad you got the knock fixed up


edit: just noticed your timing on those logs, thats insane to have that much

 

[herostar]

with no knock and that much timing you could lean it out a little more to gain a little more power (and better milage... )

 

[zross1]

With your set up you should be able to run 21-22 psi on pump with no problems. Like everyone said that timing was very high, high enough to blow a head gastket if your not careful, but it sounds like you got that under control.

 

[Blue92]

As he said earlier, his base timing was set at 10 degrees and he put it to 5 degrees. His timing will go down a bit. Post another log with higher boost, I'm interested.

I will go out this morning when i get off work. I work mids and sleep all day. I turned the boost up a tad, so i should be around 20-21psi. I don't really care if the stock head gasket blows. I am just going to run it until it does. I have ARP studs and a new metal HG waiting to go in it once it does blow. I'm just not going to do the work when it's still good.

I will post the log results on this thread when I get back. I'm also curious to see how it looks.

Well, I went out this morning and it turns out that 1.5 turns on the boost controller put me at 24psi. So I said Fu$# it and logged it anyways. I got only 1 count of knock two times during the entire duration of the 3rd gear pull. It pulled like a mo' fo' too. I think my tps might be a tad loose, it isn't what it was maxed out in the other log. Looks a lot better. Here are the numbers at 24psi on my 50 trim....and the stock head gasket didn't blow yet, dang it!!! !! Oh yeah, I took my buddy for a ride to show him how it felt at 24psi and I got pulled over cuz i launched from a stop light. Cop didn't ticket me though, I think cuz i told him I was in the military. Cool as hell.

Looks great

 

[FASTSPOOLINGST]

Well, I ended up maxing out my wot knob on lean and then started turning the base knob leaner. I am up to 2 clicks leaner on the base. I am still not getting any knock. I put it on 3 clicks lean and i'm gonna go see what it does today. I must have been running really rich.

We'll see. I'll post the findings.

 

[Mackzero]

Yes, that is probably why you had so much timing in the first place. My car was doing the same thing. After I bought my wideband I tuned it for A/F ratio and now my timing is around 18 when I get on it, and goes to about 23 or so. I am running 20 psi on a GT3255. Stock block also, but with Mits.metal head gasket and ARP. These things are pretty fun when you start turning up the boost. I want to get as much as I can out of it on 92 pump.

 

[billdo_83]

I wanna start turning up the boost on my 61 trim.
Stupid little problems :thumbdown

Good logs.
Are you running pump gas?

Me too


BTW: your second log looks great!

 

[FASTSPOOLINGST]

Yeah, I'm running pump 93 octane. I went one more click leaner on the base knob. Still no knock. Damn I must have been and am still rich. Gonna keep on leanin her down until i get it right.
