I was racing a ss camaro yesterday afterwork, I'm coming up from behind, but he swerves and gets in my way, eventually pulled next to him. Afterwards we talked, he says he was in 3rd gear(M6)(we're on the street), I was to(A4). I think when I hit 4th gear It would have been all over, but he swears he was only in 3rd playin with me. I need to get more air in my motor, she takes too long to turn over and scream.

I highly doubt you are going to be an SS with an A4, I've got an 2001 SS (M6) and other SS's cant beat me, so good luck with that. What kind of street were you on? in town? or what? cause I can do 85 in 3rd, so if you were in town, he proly was just playin with ya.

DonutMachine

i've beaten 4 c5 vettes and 2 mustangs and 1 c4 vette. Is the m6 that much faster than a a4

DonutMachine

flat recently pave two lane road, If your familiar with the Bay Area, we raced down Bancroft

DonutMachine

time for a procharger

dbmason

I beat c4, c5, mustangs, the only thing i loose to is a 6.0 gto or a c6 vette, or any heavily modded car. i've got video of me beating a c5 vette at the track. and i've never lost to an A4

DonutMachine

really cause i beat gto's, chargers, I can't tell the differeance between the c6 and the c5, they look the same to me(i think lights). I have never lost to a stick car from a dead stop in my LT1(93). He took me from a roll, acutally we both turned left and my attempt to pass him failed. Does your exhaust give you guys a definitve advantage, also ls6 intake right? never mind i'll search

dbmason

the gto's with an ls1 i beat, the ones with a ls2 with 400hp, i dont, c6 vettes have alittle over 400hp, the c6 z06 has alittle over 500hp

DonutMachine

I be going so fast I don't have time to look, must have been c5 then, there cheap now same with the gto's

I beat the hell out of my friends 2000 ss m6 in my 96 a4.

$850 is really cheap for a set of new, ported, assembled LS6 heads. Let the buyer beware.

Is your car completely stock right now? There are a bunch of bolt-on supporting mods you should do before (or when) you install heads. Full exhaust, intake manifold, throttle body, underdrive pulleys, subframe connectors. Depending on your plans for the car, you may also want tires, suspension, a torque converter, and more.

Once you've bought and installed all of the supporting mods, here's what is involved with heads:

You need to check the combustion chamber volume (it's in cubic centimeters, usually around 65-70), and calculate your resulting compression ratio to make sure you know what you're buying. The heads may be completely inappropriate for you.

You need to match the heads with an appropriate cam (up to $500), and you'll want to buy chrome-moly pushrods as well (~$100).

You can probably get away with using your stock lifters.

You'll want new rockers, but the heads might come with them. A really good set of rockers can cost as much as $1000. Sometimes the kits come with pushrods.

If you're doing the labor yourself, plan on it taking at least two full days, unless you're experienced with this sort of thing. If not, count on spending a LOT of money for labor.

Once you've done all that, you'll need to get your car retuned to support the mods. You can get a mail-order tune for $150, or you can get a dyno tune for $500. The mail order tune will be good enough, but the dyno tune will be practically perfect, and as a side bonus, you'll have dyno numbers to brag about.

You should know that installing heads and a cam will have a noticeable effect on your fuel economy. Highway will improve a little, and city will go down a lot.

Now, I'm assuming I've scared you off from getting heads.

Please tell us -- how fast do you want to go, and how much money are you willing to spend to get there? Is your car a daily driver? Do you want to race at the drag strip? Any interest in autocrossing? Are you willing to do your own installation when you buy parts? If so, what's your skill level, and do you have access to air tools, a lift, or a welder?

not true, my 3rd in my SS tops out at alittle over 85, i've got 3.42 gears, and yes they are stock

JakeRobb

Assuming everything in your car is stock:

Rev limiter: 6200 rpm
3rd gear ratio: 1.30:1
Rear end ratio: 3.42:1
Tire size: 275/40ZR17

A 275/40ZR17 tire is 25.661" tall. Multiply by pi to get circumference -- 80.618".

6200 / 1.30 = 4769.231 rpm at the driveshaft
4769 / 3.42 = 1394.512 rpm at the axles
1394.512 * 80.618 = 112422 inches/minute

112422 inches per minute is 106.461 miles per hour. If you shift at 6000, you'll be doing 103 mph.

Either you're shifting into 4th at 5000 rpm, or a previous owner installed 4.10 gears and didn't pass that information on.
