Well I ordered my SS4000 and tranny cooler from RevXtreme and can't wait!

I have been waiting to get this for a long time, but was wondering....was 4000 too much?

Car has suspension set for drag racing, full bolt ons, and drag radials....the recomended converter for the car was a 3600, but I was putting 3.73 in and they said 4000...well it doesn't look like I will be getting those gears after all. Do you think I went too big? Car is daily driven.....

Post results soon as it is in, but want feedback on your converter...

 

Good Choice

 

man, in sure but my ss3600 is great. I think you stall has a higher str so it should compensate for the higher stall rating.

good luck, im sure you'll love it.....yank rocks!!!!

 

I love my SS4000 and you will too. It daily drives great and pack on hell of a punch at WOT.

 

Our Yank PT4200 is sweet and we drive it daily. 4000 is not too big IMO. Our car is driven daily by my wife and she thinks it's just right. If you go too low, you will always want more. We also ran ours with the 3.23 for quite a while and it was fine. You'll be pleased.

 

Thanks guys....I can't believe everyone said it was a good choice....i was afraid if I went with the 3600 I would want the 4000.....I think I made the right choice.....

What kind of roll racing will it do, I do some roll racing not to mention I will not hook on the street from a stop.....

 

Not sure if you have seen this:

Three key components set the Super Stock line of converters apart from the competition:

The unique 21 blade stator was developed by General Motors and will see duty in the upcoming 2004 rear wheel drive Cadillacs with 5 speed automatics. By using a very aggressive 21 blade stator vs. the conventional 15-18 blade model, Yank is now able to offer a converter with the starting line thrust of a 4000+ rpm stall converter with the drivability of a 2800 rpm stall converter. The large windows between blades allows a good supply of oil to flow through, ensuring very high efficiency and low heat.

A large 258mm (10.0") clutch. This pure carbon-lined clutch is much larger than the 245mm clutches used by the competition. This larger converter clutch will lock-up faster and will lessen the amount of nagging slip codes so common with high stall torque converters. The Super Stock converters use the popular 245mm (9.5") pump and turbine configuration. This ensures lighter weight, more efficiency in higher stall applications, along with higher shift extension than larger 258mm converters (such as the Pro Yank series).

The revolutionary billet cover is Yank's lightest to date...even while utilizing the oversized 258mm clutch. Total weight for the converter is 28 lbs, 10oz. This is two lbs lighter than any other Yank converter.

Converter Comparison: SS3600/3800 vs. Yank's 2 most popular converters

Stall Torque Ratio: The SS3600/3800 is higher than the ST3500 and YPT4000. For the SS3600 it is 2.50. For the SS 3800 it is 2.55. This will make the Super Stock converters feel tighter driving around town and will enhance drivability for cars running less gear (such as 2.73 and 3.23 gears). This will also hit the tires much harder at the starting line, a real plus for those running sticky tires.

Efficiency: The SS3600/3800 is within 1% of efficiency of the ST3500 and YPT4000 in the 5000+ rpm range and exceeds them both in the 2500-4500 range.

Shift extension: The SS3600 has 4700-4800 rpm shift extension. The SS3800 has 4900-5000 rpm shift extension. This compares to the ST3500 shift extension of 4800-4900 rpms and the YPT4000 of 5500-5600 rpms. Bottom line: for cars with less gear, smaller cams or power adders such as nitrous oxide, less shift extension can be better. For maximum ET and mph running naturally aspirated, choose a converter with more shift extension.

 

Wow, That's a lot of info and good info at that. That was helpful. Thanks!!!

i drive my ss4000e every day.... watch your 60ft's drop

dropped mine .3 seconds
