    Re: Headers

    Ya the ONE camera idea is going to be the only way to really be able to tell on a medium platform the deepness of the tone and/or raspiness. <- if that's a word lol.

    Headers and/or maggie are going to change up the sound quite a bit. So hopefully some guys show up with a little of each. Wish I was out in Cali to meet with you guys!

    This Meet on the 5th has a pretty good turnout, should have alot of different setups, But as far as I know Ernie isnt attending, and his PMs are full.... But Im sure we can figure out something

    Re: Headers

    I am doing some work with Ernie so I can probably borrow it (db meter).

    As for the 5th, I don't know if I will be able to bring the V as this work is just eating up any time that I would rather spend on the car.

    However, it pays for the mods.

    Furthermore, I have a bunch of stuff going on with modding my townhouse that is really eating up time and money.

    You guys may have to come south for a change.

    Re: Headers

    Headers certainly woke up the V.

    Back in '04, when the V had maybe 15,000 miles, I got a baseline on a DynoJet of:

    335.75 max hp / 321.77 max tq

    Just took it to the same dyno last week with CAI, B&B headers w/ gutted cats, B&B exhaust w/ X-pipe and StealthV tune and got:

    376.65 max hp / 365.02 max tq


    Even before correcting, the temps, barometric pressures, humidity were all virtually identical. Obviously, you can't depend on everything lining up equally, but for a gauge, it's pretty good, I'd say...

    Re: Headers

    So I talked to the local LSX performance shop gurus and asked them for pricing for a tune after my header install. They said 300. Everyone with a LS engine around here praises these guys, but as I looked around their tiny shop i realized they didn't have a dyno, so I asked them how they did their tunes. They do a road tune with EFI. I asked them about getting my tune using a dyno and they said that would be extra. I heard of doing a tune this way if you are just doing small things, but not for something like a tune after header install. What are your thoughts on this? I am under the feeling that I dyno tune is the best form, but I could be wrong.

    Re: Headers

    I'm thinking about going to someone who does a road tune. I kinda liked the idea of them adjusting my tune under real world conditions.
    Hope some of the smart people get into this, cuz I dunno what I'm talking about.

    I was of the understanding that road test tuning was the preferred method, if available, as it tunes for partial throttle, as well (i.e., yields better drivability and a performance increase across all throttle positions), while dyno tuning was only good for WOT tuning. Due to the more thorough and time consuming process, I thinks it's also more expensive than simply dyno tuning.

    Re: Headers

    What about a program like EFI Live (or likewise) where you can manipulate tables in 200rpm incriments of all throttle positions? You could probably use it on street or dyno...right/wrong??

    When you dyno you don't just jam on the pedal and go, you ease it up close to redline. Then look at the timing, A/F ratios and tune accordingly. I wonder if that's how they tune it w/ a road tune?

    That's how my tune was done.

    Re: Headers

    That's how I will be doing mine. Already have a laptop setup with EFI Live. As soon as I get a free weekend I will be playing around with it before the Maggie gets installed.

    Re: Headers

    Thanks for the info guys. I didn't think the folks around here would lead me astray with this shop. Now I just need to get my motor mounts and diff replaced so I can put these kook bad boys on work on grenading the new one. I can't wait to join the header elite.
