Edge racing high stall Torque converter!!!!!!

I just finished installing my 3000 high stall torque converter. ben driving around for 400 miles now with it and it is simply amazing. Not only does it jump off the line like a monster, but it made my 100+ pull a whole lot better its a night and day difference i def give all thumbs up to andre at edge racing WOW!! n i dont have FI !!!!!!!!!!!!!!!!!!!!!

Def worth every single penny:J AMINJAMIN:

I seen this before, its only beneficial if you drag, you actually loose some WHP apparently.

And it heats up your tranny fluid a lot more. Since you normally do not go above 3k in the city or highway cruising.

A higher stall TC will definitely run hotter around town. Higher stall = more slippage = more heat. There's no way around it. The kicker is the OEM TC has a listed stall speed of 2800rpms so going to a ~3000rpm stall isn't going to be a huge step up so a tranny cooler might not be warranted.

It really depends on the efficency of the TC. A good TC won't bleed off power and some might actually power over the OEM TC. The OEM TC in our cars is pretty efficent and high tech, so my guess is the Edge TC is just a modified OEM TC and much of the efficency is preserved.

The downside to many higher stall TCs is that the throttle can feel mushy and elastic around town. Not until the rpms get near the stall speed does the throttle feel more connected. The obvious improvement is in the car's ability to launch at a higher rpms and with great torque multiplication.

With my G, I didn't want to loose out on throttle response or around town driveability nor spend $1000+ on a TC and install. I choose to spend $350 and put in a 3.54 vlsd gear which increased overall torque multiplication by about 6% and gave me a much needed LSD. Throttle response around town and on the highway improved, the car launches a bit better, is better on the auto-x, and I only gave up about 1mpg on the highway. It's all in what you want to do to the car.

Hey Daveb, from what car do i need to get the rear end from. Is the rear end you have the same or different as the 3.7 gears? I want something a little more off the line and a vlsd would b great. what do you recommend?

My 3.54 "pumpkin" came out of a 6MT G sedan. It was a simple bolt in. The 3.69 geared pumpkin from the 07+ G sedans has a different driveshaft mount in the pinion. Basically you have to unbolt this part and then install the one of your existing pumpkin. See the thread in the Drivetrain section about pumpkin swaps. It will answer most of your questions. Keep in mind that you'll likely loose the use of cruise control if you go with the 3.69 gear set.

I'd go no deeper than the 3.69 gearset on the typical bolt-on VQ35DE. The VQ35HR and VQ37HR use the 3.69 gear set because they rev out to a lofty 7500rpms, the tires are 2.5% taller, and the they're are a bit heavier. The HR cars need the additional torque multiplication to get their heft off the line and to operate effectively in higher rpm range.

I understand that a high stall unit can allow you to rev higher on lauches but I'm not willing to put up with the addtional slippage (aka throttle response loss) in my day to day driving. I've been trying to improve my throttle response with my mods, not hurt it. Just my perspective.
