Cam or Gears

I see many people picking them up for less than 300 (without install kit)... problem is 3.91 from the 1LE is probably too much if I want to go forced induction down the road.

It seems 3.45s are the best for a blown A6, but like cave said.. it is not a huge jump and it could be 10-24 months before I get a blower installed so I would like to have a little fun before it happens... but I am curious if a 3.7-3.91 will never hook with street tires or the Invo's I plan to buy next.... it is a street car, I don't launch all over the place but occasionally I like to let it rip.

come on if you can afford a blower, you can afford some tires.....

I have often debated this same quandry.... cam or gears? I love the sound and attitude of a cam but I'm affraid of loosing some low/mid torque and drivability. Now that I see that I can get GM 3.91's at a good price it's a no brainer for me! It'll be 3.91's! Cam will have to wait. I'm not going with FI so I think 3.91's would be perfect, even if I go with a cam in the future. So, my vote is for gears, at least for me. OP, go with what fits your future vision for where you want your performance level and usage to be. Lot of good advise here!

Edit: I just saw your budget was $2200-$2300. Heck, you could almost do both cam and GM 1LE 3.91's for that budget!

If I was in your shoes I would go 3.70 gears. Even if you go with a supercharger as long as your not in the 700+ RWHP range then you probably won't need the 3.45 gears. Most of the guys that go back to 3.45 are big motor, big PSI type cars. At least that's what I've seen on here.

With 3.91 gears on street tires my car hooks fine unless I want it not to. Turn off all the nannies, go about 5 mph or so, suck in the clutch and hammer it......it gets all crazy then. However, if I just drive in 1st gear close to 3k RPM and then just go WOT....the car just goes and it pulls way harder than before. That's where the butt dyno really loves me some gears.

At the track with steet tires and the gears I'm still hooking about the same as I was before. Not that it's great but I was expecting it to be worse with the gears. So far that hasn't been the case. I still got some 2.0 60' times last time I was out. I'll know more in the next couple months though when I take it out in cooler temps. The last couple times I was at the track, day time temps were in the 110 range and even at night we were in the mid 90's.

are the 3.9 gears too much for a supercharged car? i don't really drag race, but wanted be able to get a quicker feel around town, the car still feels heavy I have 305 rear nitto RRR on my car and it hooks up good, any ways thanks for the help.

I don't have a supercharged car but if your car feels heavy with 3.45 gears then I can say that the 3.91 will really wake it up.

perhaps, but I cannot justify the cost... I don't have access to a strip here, so I have to drive a ways to get to one... because of that I will only be at the strip maybe once a year tops.

It is 99.9% street, and if I cannot hook on the street with the 3.7-3.91s and a blower it is a moot point.

well, I am sure you aren't planning on street racing, especially with treaded stock type tires, no matter what gear you're running..... it's not like you won't spin with 327s.....

I'd say a blower is the moot point in your case.

Torvec Isotorque Differentials

--------------------------------------------------------------------------------

We had a chance to check out he Isotorque Differentials at c5Fest3. I believe this is my next mod before my cam. I like the way it works with current or additional gearing to create better traction and control for the car.

I am a novice here, does anyone have an opinion on this product?

That's a very interesting product design... Wonder how good it works, how durable it is, and the cost?

[edog]

Im not sure, but I thought it was a very nice concept. I am going to give it a try when it releases. Im starting to do research on it now. Cost was around 1350 after a 300 dollar discount for signing up at the fest.

If it is for me, then it is for 9 out of 10 owners on this website that purchase blowers..

With that approach, I should not have done headers, cam, gears because I won't use the power on the street....Even if someone were to dabble in street racing, he probably wouldn't have the space to tap into all that power.

because none of us will truly use that power on the street, but we buy those mods anyways, don't we? It's just fun to have it if you can and have the power there when you need it.. maybe its fun to take the car to shows?
