Fat-Tony Member 5,364 Member For: 18y 7m 20d Posted 06/08/08 12:38 PM Share Posted 06/08/08 12:38 PM I thought the moral of the story was don't bother wasting your time and money with the 4 speed auto, if you're chasing number's?No reason why you can't have 350rwkw treated nicely and tuned properly pumped through a 4 speed and not run quick times. But you're right, chasing times, it is really a waste using a 4 speed. You got to take into account budget and intended purposes for the car.

But I do drive my car around on ET Streets all the time.When the box comes out saturday morning we'll find out the cause of the broken plantry's, Last set we pulled apart was due to the oil pump drive sh*tting itself. Lets hope mines the same! Link to comment Share on other sites More sharing options...

Our cars are fairly hard on the driveline because of the weight and torque. This puts a huge strain all all drive line components. 500+ rwkw and 850+nm pushing around 1800kg will tend to do that.From my recent research, a C series can be made to handle the 500+rwkw I require, but it would still need regular maintenance and in the end be less reliable and more expensive than a Powerglide. Even so, you srengthen the trans and the strain is shifted elsewhere down the line so you will need to look at the tailshaft, axles and diff. You can get a 1200hp Powerglide, converter and Gear Vendors overdrive for around $7500. Not only would this be a stronger, more reliable and in the long run cheaper alternative to a C series, but with the Gear Vendors you get 4 gears with a true overdrive 4th for economical cruisng. Maybe not 2000rpm at 100 but a whole lot better than 3000rpm at 100. Somewhere around 2250rpm at 100 depending on the overdrive ratio you choose.I'm budgeting 10k for complete driveline and I think it can be done for this with some work being done myself. But it will be an awesomely strong race setup (1200hp trans with transbrake, billet axles and tailshaft = massive launches!) yet still maintain driveability and fuel economy via a lock-up converter and overdrive 4th. that's my theory anyway...

And im not trading up to the BF as got too much cash stuck in my Ba already. Link to comment Share on other sites More sharing options...

A number of cars I know of are still going strong on their 4speeds.If you were to push the limits over 400, different turbo etc, then yeah.. a 4speed might not be upto the task.

Your box is dead now, I wouldnt drive on it until you get it swapped out.. all your doing is sending metal through the entire system.. Not good, and much more costly at repairs.was your plantery's swapped out with PRE-BA plantery's? also was the front pump also swapped out in the previous build?

Headsex Donating Members 2,528 Member For: 19y 2m 30d Gender: Male Location: Melb Posted 08/08/08 02:36 AM Share Posted 08/08/08 02:36 AM There's no reason why you cant crack a 10 with a 4speed.. Many people have done it. I believe Dion has done a 10.20 odd in a ute(read: heavier than sedan) with a 4speed auto.torque limits are easy to manipulate, both torque truncation and shift torque reduction. via throttle shutting and or spark retard..What torque limits are posing the most problem?
