Longtubes with catts. Gmmg Catback. Ported stock TB (Bo White), Stock MAF (screened), LS6 Intake (stock). Stock Injectors. No pulley, No Fast. My goal with NA was to do it by all airflow mods. Fast was out of my budget (sorry). I learned how to do my own tuning. Idle is at 700-800 Rpm. No bucking, surging, etc. Luckily I live outside of the current Colorado Emissions Testing Zone. But, I understand your dilemma. And to the OP, sorry if we are hijacking your thread. Just trying to help out the other LS1tech Member. ..WeathermanShawn.. |
I had to look at the date on this post. This is the subject that started a lot of arguments back in 2001. :nod: |

http://images.ibsrv.net/ibsrv/res/sr...r_banghead.gif That sucks 4 me Is it possible to have a cam that matches the goals and performance of the Pred Z 228/232 recommendation and still pass a true sniffer. If so what type of specs. 219/223 .607, .610 112+0 LSA -3 * Overlap will pass with "lean" tune. |

I passed the sniffer test with no problem...not even close. |
the problem is, well not a problem but if the cam peaks at 6200 your not going to shift there, i peak at 6350 and shift at 6500, so a 6200 peak might be a 6400 shift point. |

On another thread about 'why do they market small cams anymore', (thread has been going for years), they has been a discussion about a 218/224 113+1 LSA cam that might be up your alley. Mr. Predator-Z helped spec my cam. As far as I know he still gives advice for free. You might 'shout-out' to him, or P.M. him. Otherwise, that thread has some great insight. A lot of 'old-school' type education, but people were running 11's on just small cams. Gets you thinking.. Hope that helps. ..WeathermanShawn.. |
get a comp cam in the lsr line they have done all the home work for you |

So it makes me always wonder, other than bragging rights, why go with a 230+ cam just for a few tenths when running a full weight car? |

Why do a cam at all to only gain a few tenths? That extra couple hundredths of a second is more important to others. I think at least though a 228/232 0.600/.600 is the biggest I would ever put in an LS1. Would make excellent power andStill wouldn't trade up any bottom end for peak numbers, any bigger and drivability and idle quality start going out the door. I agree to a certain extent. In a A4 bigger cams surge if you let off the gas to quick or cut the wheel to hard even with the best tuning. You're still going to get alittle surge. Thats the nature of the beast. It's just what you can except. I personally hate surging for a difference of 6 to 8 rwhp. In 6 speed cars the bigger cams tune nicer and don't surge nearly as much and at 900 rpm you can almost get rid of most of the surge on a 228 cam. But if i'm going over 220 degrees in an A4 i'm gonna bite the bullet and go with the biggest i can get without having to fly cut. But i dynoed 407rwhp and 395 rwtq in a A4 with my Vig.3600 with the 216/220 cam. And after my installed a TR224 114lsa cam i only made 6 rwhp and it stalled went backing up and surged at stop lights since LS1-Edit just came out or my only other option was Ed Wright. I got so sick of the car i went back to the 216/220 cam and ran similar times but with no stall or surge. So the driveability in a new WS6 was more important and a few HP. It all comes down to what you can except as far as driveability and i didn;t want the idle issues, unless there was a 20 rwhp difference...lol. Plus a few tenths is nothing to sneeze at. I wasn't talking about my car i was talking about guys running 230+ cams. i had buddies that ran the 228 cam and didn't gain that much over the 224 cams. |
Those are pretty good numbers for a 216 cam with ported 241s. Only 13rwhp shy of my TR224 with ported 243s. Like the MS4 (239/242 .649"/.610" 111) usually gives around 415-420rwhp and a custom spec'd 228/232 .600/.600 112-113 could give 405-410rwhp. I don't see that additional 10 degrees of duration and additional lift being worth only 10rwhp for a daily driver at all. And with that low/mid range I don't see the MS4 winning either. |
great numbers for that small of a cam.I like the LSr truck cam,215/223,112lsa+5.good torque cam. |
