Saw this over on LS1tech. They have the record for the fastest IRS 5th gen in the world with one of the Level 7 4L60e RPM transmissions. They ran 8.943 at 154.5mph.

4000lbs + 1000hp + 4L60e = 8.94@154mph and a new 5th gen record - LS1TECH


Seems like RPM knows how to build a 4L60e to last.

 

Nice, but if we add 1000lbs itl be rated at 700 hp lol

 

They were biting their nails the entire pass.

 

True RS/SS 4.8

 

Maybe fo you, hell I weight in @ 4200.


Damn that is bad ***, I wonder how many passes it lives through.

 

"This is a true testament to the abilities of our 4L60/70e transmissions. This transmission has over 70 full passes and many more partial test passes on it with only one minor problem."


Impressive!

 

Definitely impressive for a 60e. Most of us would rather not be wondering how many passes it lives through, though... I'd prefer to lose count with an 80e

 

Yeah mine weighs around 4200lbs also without me in it.

 

That's impressive!

 

Pretty impressive. Put it on the street and do a few 3-1 wot runs and see how long it will last.
