LET High-Stall Torque Converter
-------------------------------

LET Motorsports is proud to announce the release of the final piece of the 55K performance puzzle - The >>>LET high-stall Torque Converter (HSTC)<<<

This modified factory unit is designed to put more of the power you already have to the ground, without sacrificing drivability at all. Some customers have reported better-than-stock drivability with the HSTC installed !!!

Stall Speed is increased several hundred RPM to a more performance-oriented level, which varies depending on your supporting mods. The low- and midrange are substantially improved, with no loss in top end - the HSTC retains all factory lockup characteristics, as well as an improved Stall-to-Torque Ratio (STR)

This unit will net you a 0.250-0.400 second reduction of your quarter-mile times, and possibly more. Thousands of development miles have been put on these modified units with no failures and no warranty issues, so you can remain confident in this mod for years to come. Use of a factory core means no flagging or refusal of warranty work.

The HSTC is an ideal first mod, as well as being a great final mod to complete your performance package. The HSTC is docile around town, yet enhances your car's acceleration unlike any other mod available, at any price.

Pricing is set at $1200.00, with an additional (refundable) core charge.

Promotional pricing, for the first run of units, will be offered at $999.99 !!!! (plus shipping)

Please add your name to the list below to guarantee your spot - this promotion ends February 28th !!!

I have installed a LET HSTC in my e55 for over a month,and i must say of all the things i have done to my car this is by far the best bang for the buck....when it reached the stall speed it feels like you hit NOS,i should know;i have NOS on my car.This past week i beat a mustang with a stroke chevy 406 motor on slicks,with me running on 19"wheel w/ps2.
As for drideability the car drives better,and smoother than stock.I drove the car from the Carolinas to Miami 800 miles one way and back.Then to Virginia 250mls one way and back.

If I may ask....why can't this be used for the 65 tranny...or can it? , I was thinking about this the other night and will do a bit more research to see if could be done.

I cannot believe how it transformed my car.

My non-header-equipped car is verging on 11-flat with this mod, and I predict a non-NOS 10-second pass this Spring.

If you guys want a 1.5x 60-foot, this is the mod for you.

My 60-130 times dropped almost a full second (0.9 sec) on an already quick car.

On one particularly violent launch, the car actually thought it was being rear-ended, and I swear it hit the brakes !!!!

PM sent.

It is about time! Count me in.. Maybe you could have mine set up a little looser over the average run..hehe I like mine loose!

No doubt, will be one of the best mods to come our way yet..

+ 1 one on improving drivability..

V12Godspeed

Thanks. Replied!

Can someone elaborate or educate me on how this mod works and benefits...sorry...lol!

raising the stall rpm allows the torque converter to slip to a higher rpm. launches will be greatly improved with this.

kinda like slipping out the clutch in a manual car.

will it also improve shifting response?

congrats on making this mod available to the mb community, this is for sure one of the best mods you'll do to your car but the price is way to high imho

Got a quick question
If i don't drag race my car will this mod be valueable to me. will it make me feel like my car has more tq.

prodigymb

it will be very valuable for drag racing

chiromikey

jamusa and chicagox,

can you guys provide some pre/post 60ft or et data for comparisons. also chicago, how did this improve your 60-130 time so much???

V12Godspeed

So this little mod with 900 RWTQ should make me come out the hole like a bat out of hell...Damn!!!

blackbenzz

No, you will just lurch forward and hear clank clank clank

Torque converters in general allow you to launch higher in the rpm range and therefore launch harder. Definite gains in the 1/4 mile if your drivetrain can handle the abuse. Some negatives are: decreased gas mileage and a sloppier feeling pedal under the stall speed. The car will rev but the car feels like the trans is slipping kinda. Then it hits the stall speed and just grabs and goes. Th eharder you launch, the more stress you put on parts. This is exactly why I break so many axles. Anything above 1500rpm launch and my axles snap like twigs. My axles are probably much smaller than the other models but also remember that it is much lighter and making wayyyy less power.

It will be interesting to see how these cars handle the harder launches

jamusa

Definatelt......especially for overtaking,or roll on.

jamusa

I cant give you pre/post,because i dont track my car, but i have had several race where i have put more distance or shorten the distance on cars that i have previously raced.
Wayne on the other hand can give you comparison.

Exotic-metal55

Yes sir! The more Torque your car produces from either adding mods or twin turbos will increase the stall of the converter.. The other nice advantage ,, is that you will not have as much RPM drop on the shifts , thus quicker ET or street acceleration..

Chadillac2000

How much for installation?

ChicagoX

I was afraid that this would happen, but after much R&D the drivability is AMAZING !!!

Jamusa told me that his Mercedes Tech, after putting on 100+ break-in miles on his car, asked if the unit was modded at all. You can tell he didn't stomp on it.

If anything, my modded car is less twitchy around town than it was....more stock-like in that regard. A firmer stab at the pedal an all hell breaks loose.


1.67 60-foot to 1.5x 60-foot, with over 3/4 tank of gas (duh) and snow tires on the front.

I went to a track rental down South, and was running late for the track. This meant that there was no time for a swap out of the snows. At the last fill-up, I also forgot to NOT put gas in my car, and ended up with waaaaay too much fuel.

The 60-130 times were done with a GTech ProRR, averaged over 9 runs with each setup. I thought I had done 10 before the HSTC, but there was only data for 9

I think the advantage from a roll is compounded - hence the difference between the track times and roll-on times. The car simply jumps out now when hammered...like it dropped 5 passengers.

Best - mod - ever. (Comicbook Guy voice)

V12Godspeed

Wayne, what were your 60-130 times if you don't mind me asking...

ChicagoX

Under 8 seconds is all I can say.

bassn_07

What should we expect to pay for install and is there any kind of warranty?

V12Godspeed

Are you kidding me...Impressive!
