Running a Vinci Cam? Please come in.
Running a Vinci Cam? Please come in. I'm running A vinci XXX cam (specs in sig) with AFR 205's 63 cc on an LS1. My dyno numbers are way low 365/351 with a locked converter. Anyone else running the same or similar combonation on an A-4 car? What were your results? I think there maybe something wrong with my car.
Post the dyno sheet. Also, what springs? The 832's? My VHP cam is smaller but I am close to 400 with an MN6, the Crane 1.7 rockers and Dart 205's. I don't think its the cam or the heads, if the 832's are being used I would like to see the dyno sheet as they "could" be an issue. I would suspect either the tune or the dyno. Is this the same dyno you used previously?

I'm using the 833's. Its not the same dynoas before.The Graph is below. The lower numbers are from the previous time with the Patriot heads. The speed inc numbers were 378/370. They tweaked it a bit more and came up with what are the lower numbers on this posted dyno graph. The higher numbers are with the AFR 205's.

Boy, I don't know. The top only came up a little but the bottom came up a lot. That cam has five degrees of advance. Do you know if they degreed the cam? What did your 056 cam curve look like? Have you contacted Roger? A cam with less advance will give more power later, but you might lose on the lower end. That was the question I wrestled with for some time, and in the end the way I drive the car 99% of my time is spent below 4K RPM so it didn't matter. Big question is, how does it drive? It must be a monster with the converter.
Here is mine with the 056 and Dart 205's.

Matt, your setup is off, either by cam timing or some combination of installed parts. I am done with vette for now, look at my sig, very pleased with the outcome. Did you make $ on the PP heads?
Something has to be wrong somewhere. your running a smaller cam and making way more power. I compared my my dyno graphs from when it was tuned at speedinc. and when I ran it on Val's dyno and there seems to be about a 20 hp difference between the dynos. But even if you add 20 to my current numbers they are still low.

All you guys with Vinci cams. Can you please email me a copy of your dyno graphs? Then I will have something to take back to the tuner and the tech that did the work on my car. Thanks in advance. tshmrh@sbcglobal.net

You should be able to copy and paste mine, if not I can send it to you tonight or if you need more resolution I have a bigger one. Send me a PM if you need it.

Lifter pre load is 1 1/4 turns, which Rodger said is just fine. Joe says I need to learn how to read a graph. He says there are major gains accross the range. He also said peak numbers don't mean anything. Ed Curtis thinks I should install a fast intake and Nick Williams throttle body which he thinks will gain 40 hp or so. Heres the thread...

Ed's post are on the last couple of pages.

Which intake are you running now, LS6 or LS2?
Can't disagree with Joe, as I stated earlier you picked up a lot down low, about 40 hp at 4,500 RPM. You might also want to contact Tony Mamo, he may have insight from the head side and he is very knowledgable about the FAST Setup. Do you know what your MAP was reading up at the upper RPM'S on the dyno? Maybe it is starving for more air.

Look him up in members and shoot him a PM is the best way. He responds pretty quick and knows his products very well. I am sure he will be able to give you some suggestions.
