VVT Cam .......... or ......... LS3 Conversion
Ok. I know this info is spread out all over the place but I want some opinions with the idea that it will be for me.
I may be doing the install myself..... (In case anyone hasn't seen it, member robertway did a diy write-up that is second to NONE in scope, and thouroughness with easy to understand vid, text and pics. Fantastic job.) I want to hear opinions on the pros and cons of a VVT cam and an LS3 conversion. My relevent mods are catless long tube headers, (Borla, so 1 3/4 primaries) 2.5" exhaust (also Borla), Fastlane cai, Magnuson TVS2300 supercharger, and it's obviously dynotuned. Everything else is stock. Obviously it's an L99. I'm hearing conflicting ideas and possibilities. Until yesterday, I thought VERY few people were doing VVT cams. Now, you'll need to know my goal with this. This will be my last power mod. With respect to the engine, I won't be doing anything else. No NOS, no blower swap, no underdrive pulley, nothing. My order of importance is power, then sound. I want as much power as I can get and not be rocking all over the place. I'll do a stall, and possibly rear end gears later, but this is my last power mod. So, opinions? Insights? Lessons? Any info I can get will be great. Including wether I should do it myself or not, and where to spend my money at. Thanks in advance. |

I'm doing the LS3 converstion. I didn't want to limit my cam options so much and I am happy to put the better lifters in my car. It makes it easier all the way around. I believe the the tune is far more important anyway and I have a great tuner.

This will be an interesting thread to watch. About 3 weeks ago I was trying to make this same decision. But I ended up deciding to wait and do a cam at a later date.
At first I was leaning towads a VVT cam setup (Mast Motorsports) or comparable setup. But then I thought I had a lifter issue and the heads were going to have to come off and the lifters replaced. So at that point I figured I might as well do the LS3 conversion so I would have more options in cams to use and I wouldn't have to worry about the AFM/VVT lifters, etc causing an issue some time in the future. I know someone just recently had an issue with a VVT Mast Motorsports Cam setup on his supercharged L99. I see if I can find the thread. It was actually a broken value spring. Here's the thread. But I really like the stuff Mast Motorsports is putting out. http://www.camaro5.com/forums/showthread.php?t=132873 |

Nope. It's like a butterfly. Yes, technicaly it's a larvea or whatever when it's in a cacoon, then it becomes a butterfly. BUT, it was always a butterfly. I'm still L99 becasue it was that way at birth.

But.... why? Quote:
More options in cams is good, but if my choice were found in a VVT cam anyway, then it woldn't matter. But I haven't really looked yet. It's the specs that I don;t have a clue what means. I'm basically mailing down the VVT or Conversion decision before going any further. Could be that I need to approach it from the other end. I just want to get opinions and info first. |

You're going to get a ton of different opinions here, but I think with the blower you really have all the power you need. You can go to a smaller pulley and make more boost. Once your cam goes in it will drop your boost anyway so you'll need it.
I went with a Comp VVT cam because I really just wanted the sound. An LS3 conversion is more expensive as well, but if you're doing your own labor you'll save a bunch. If I hadn't gone with a blower I would've gone with a larger cam and an LS3 conversion. Just my opinion...since you have the blower already...go with a VVT cam (and a torque converter). |

Here's the thread I was talking about. He had a VVT cam setup and the car worked fine. But when he put a supercharger on his car he ran into some issues. http://www.camaro5.com/forums/showthread.php?t=132873 |

My car is a bit underpowered considering the mods. Blown with all the components and only 471rwhp. Ya, the wheels don't help, but guys with 22s have had better numbers. I'm not neccesarily chasing a number, because I wouldn't know what number to chase, but I do think I'm underpowered now, considering. Maybe my borla headers with the small primaries is hurting? Nto sure, but If I'm gonna do a cam, I want the max power benefit I can safely get. |
