HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

I'm wondering what the most people run for torque on the transaxle? I'm wondering if stroking it will put way too much torque on the gearbox.

The popular/common consensus for max torque for these transmissions is ~400 ftlbs torque. I believe that to be quite conservative. MichaelB puts out crap-loads-more with his supercharged LS. No problems reported at all from him. But, there are quite a few variables such as which tranny (turboS > turbo cooled > turbo > NA > nothing...haha), tires (size, rubber, temp., street), the measured mass of your right foot (at any given time or mood), the condition of you mechanicals (tranny synchros, gears, pinion/ring mesh, oil, bearings, etc), and of course, any kinda "Type R" stickers in your vicinity; either on your car or persons or on some other car or person in the lane next to you.

^ All serious factors.

I ran the living daylights outta my NA box with the LT engine. But now, I have the LS3. pale Which i thought could be trouble but after some calculations and tuning, my tuner told me
"390 rwhp without bend at intake and 380 with bend."

Not what I expected but still under the popular consensus of max 400.

It also has a lot to do with how you drive the car, size of tires, type of transmission.

The whole drive train is one connect system. Daily driving and fun should be fine, hard drag racing, big, sudden loads on any of the component systems, can cause failures. Things like dropping the clutch, going air born with hi-rpm.

What are you building for, What is your performance design and how have you designed to compensate for the projected loads in your drive train?

As an example, If you load up more Torque and have big grippy tires and like to drop the clutch hard in first gear, your applied load factor by torque will stress the hell out of the transmission, (pinion gears), axles.

Wild Bill has had some good comments on the strength of the automatic to take hard drops.

944-LT (LS) is right (and funny!). I have shoved a lot of TQ through the system for a long time without worry. But as Vorsche says - it depends on how you drive. My days of having to beat on stuff at every stop light are not as common as they once were. And I find that I treat the machine pretty good because of that. But, I run a 951 box, freshened up with a N/A 5th, and a Quaife diff running through the factory cooler on 295 sticky race rubber. And I drive it sideways most of the time - with a blower LS1 - and it lives. cheers
