Changing Gears

[rgnbull1227]

Yes. Engine is a Performance Engineering built 331 Stroker. 415hp and 410 Trq. Ive had big HP cars previosuly(600hp Lambo, 500+HP BMW, 450HP Lotus, ZR1, etc.) plus lots of track time in cars/race cars so Im pretty good with the right foot. Everyone said even with 400+hp this is a fast car. Now that I have it....looking for more. The problem is I love the drive-ability of this engine. Its a great driver and it is definitely fast, but looking for more. I am looking at building a 427 Stroker with 500+ hp as well so the gears may be going back to a taller gear once a new engine is in place.

Im running a stroker 427 with about 550 hp. The 3.73 are fine and so would anything up through 4.10. I dont know what to tell the people who say it would be useless other than your welcome to come for a ride with me and I can show you how useless they actually are.

What drag radials are you running, and what prepped streets do you drive on?

Or are you talking about tracking the car and how it comes out of turns in 2nd gear or greater?

I've run drag radials on plenty of cars. I have used my car on the streets many times. I've been on the track a bunch of times. 450+rwtq starting at 1800rpms is going to light up the tires in 1st gear on the street, and at an unprepped track.

I am trying to grasp how you are able to do it, but I just can't come up with a logical conclusion in a car that has 1300#'s over the rear tires.

In a a car with substantially less power, that won't have the traction problem to this extent, I understand the reasoning for a lower gear. It's a quick way to save money and get the desired results. But there are two different discussions going on, one with you and one with the OP, rgnbull1227. Spinning tires is useless IMO. Your opinion on what the definition of useless is obviously differs.

Im running Mickey Thompsons. I dont know what to tell you. I come off Idle and nail it. Others with similar set ups do the same thing. Greg Schroeder is a prime example. If useless in your opinon means dumping the clutch at 2k or more and not spinning than I guess you are correct. But to say you will have no traction and that the car will be undriveable is 100% false. How do I know this? Beacuse I do it!

Greg Schroeder does it on a prepped track with ET STREETS. Have you tried driving around on aired up ET streets...on the street with no heat? They suck. There is NO traction with them. Heated and aired down, great. Otherwise, no. And don't even attempt any turning on them.

We are not saying the car will be "undriveable'. We ARE saying that any gas given in first gear is a waste. You are really sitting here telling me that with 450rwtq (and it's funny to think that 450rwtq isn't even that much), in your go kart of a car, you can come off idle on the street (or from a roll in 1st), nail it, and not spin?

I just, well, I really just don't know what to say or how to even respond to you. Congrats I guess. It's really an amazing accomplishment.

I keep my tires aired up and they do not suck. You clearly have no experience with the Mickey Thompson tires. They actually handle pretty good with air in them. Sorry your first gear is a waste but I assure you mine is not. Yes I can come off idle and from a slow roll in first, nail the gas and not spin. The front end feels like its about to come off the ground but it does not spin.

If you dont believe me your welcome to take it for a spin and I will show you the miracle that we call first gear.

I also have a miracle called first gear, but mine thrives on a 3.27 rear axle ratio. I absolutely do not disbelieve you, but I do find it completely contrary to my experience. I wonder what engine you are running? Is it possible that you are running a peaky motor? I have run the M/Ts on my car and can smoke them at will in low gear above 2000/2500 rpm with a fully engaged clutch. I am quite jealous of the incredible traction you are achieving and want some for myself!

I actually have quite a bit of experience with the mickeys, both the streets and the street radials.

Aired down a little with drag radials the car should hook up from a roll with 3.55s or higher. 4.10s no, unless they are heated up a lot (talking specifically for our sbf 427s). Off idle punching, it's going t spin.

Anyway, that got off tangent quick. I added my 2 cents and hopefully future readers use an ounce of common sense to figure out what is being discussed (specifically the definition of "useless" when referring to 450rwtq with 4.10s on the street, in first gear).

A 4:10 gear is a great gear for a Cobra
I have run them for years and love them.
If you haven’t run them in a Cobra how can you offer a valid opinion? A wild-a$$ guess adds no value to the discussion.
Here is another recent thread
Rear end gear question
You girly-men are STILL good for a laugh! It doesn’t matter what gear you run if you have crappy tires. Goodyear GTIIs are worthless, greasy, spinning $hit-piles even with a 2.90 gear and 450hp. Put a good sticky tire on the car and you will realize how quickly that you can use a lot more gear.
Rgnbull,
Are you just collecting parts to have it done? Or are you going to do it yourself?

Go post a video of you driving around punching the gas in first gear with 450rwtq , and how you don't spin the tires. "I'll believe it when I see it".

And we can comment because we have decent tires, and spin the tires with a much higher gear. And we have driven other cars with drag radials...and 4.10's, or whatever other combo.

The reality is that a 2600# car with one of the many lower rpm 427 SBF's will be useless in first gear with 4.10's.

ETA: I can't even comprehend how this is up for debate. If you want to say that you like 4.10's because you have more fun spinning, that's perfectly fine. But again, I call that useless. Obviously opinions and definitions of useless differ. However, it sounds like you are indicating that 4.10's are not useless by traction standards which goes against reality (talking about with any bit of power).
