Here's a video of a 675HP / 925TQ SL600 RENNTech vs. a 600 HP Viper at the drag strip. These twin turbo V12 Mercedes engines really are amazing.

how about some vids or pics of your Shelby? I'd love to see that bad boy.

 

I'm going to give it a go and see if I can get through tech inspection at an upcoming drag day for a club event. I'll post videos if I get in. I'm not sure if my little roll bar will pass for a speedy run.

 

well how about some pics? I love those cars.

 

here are a couple

 

I don't think the RennTech SL600 is a twin-turbo, it's normally aspirated. Now the NEW SL65 AMG is a twin-turbo V12!

Man oh man, that is gorgeous! One of my dream cars for sure. Absolutely beautiful.

 

The old V12 mercedes is N/A, but all of the newer 600 series Mercedes are V12 twin turbo. They're just sleepers. With the RENNTech ECU and TCU upgrade wheel HP and wheel TQ looks about like this. Yes that torque is some crazy action. Keep in mind this is a Dynodynamics dyno pull. Add some for Dynojet numbers.

The SL65 AMG version of the V12 twin turbo looks about like this after computer flash and transmission . The top line is the stage two RENNTech

gorgeous.....

 

Yeah you have to love the new ecu's. Now its just a flash to my Dinan 7 and I can run a supercharger or twin turbo system without ripping apart the wiring and installing a EMS. And then if you don't want it just reflash it back to stock.

 

Around 800hp @ 3000rpm??

Umm holy ****.

 

It's amazing how much torque that auto transmission is handling and still has overdrive. Sometimes I wish I had an auto to just flood it an go like that.

 

i would think with all that power it would be in the 10's but i frogot that it weights 4491 lbs (HEAVY ***)


damn i love that cobra greg

 

my thoughts exactly, both of them

 

We had a drag day a couple weeks ago at Speedworld, Arizona. The corrected elevation for the day was about 3200 FT with also a serious head wind of 20+ mph. The twin turbo V12s on drag radials were pulling 1.6 and 1.5 60ft times with low 11s in the 120s mph. At sea level no doubt they would be 10s close to 130 mph.

Here's an elevation and weather condition correction calculator for track times and speed.
