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 …

What is the transmission limit? hp/tq?

Post  bp944 on Mon Dec 24, 2012 12:44 am

I would love to build up a high HP ls1/ls6. My worry is that I'll destroy transmissions. I know you cannot drop the clutch but with HPDE or autocross where does the transmission give in. I would have the reinforcement plate, LSD, and a cooler in the transmission. I would love to get my hands on an AOR transmission but those seem to be hard to fine. It seems the stock tranmission is the way to go since everything else would require a decent amount of fabrication (audi 016, T56) and a lot of cash(911 transmission). Could I run a lot of horsepower with a light rotating assembly, flywheel, and clutch to reduce the strain from all the momentum? At what hp/tq do people start breaking transmissions? Should I start with a na trans and really practice driving something with high hp and a weak tranny?

Its all about the driving style really. Ive heard numbers like 400hp as the limit but I think all the tranny carnage is due to a short and high rpm range from the 4 cyclinders' power band. Its a very tremendous and sudden load on the old R&P which has the devils chore taking it all. The V8s however produce a smooth and relatively broad and level power band which in turn doesnt produce such a shock on the drivetrain.

Absolutely! If you already have an NA box, by all means use it.

Over on the turbo 4 side of things, guys are making 550+ ft-lbs at the flywheel, the stock 951 box is insanely stout as long as it isnt abused and the clutch isnt dropped. Its a tougher transmission than its given credit for.
