So stock M6s all dyno around 410RWHP (DynoJet numbers) in stock form. Since the dyno-cell is not finished, we ran all of these tests one after the other on a Mustang Dyno.

With JUST the custom straight-pipe exhaust, the car put down 422RWHP which is corrected to 447.03 RWHP! That’s approximately 37RWHP +/- from just the exhaust.

Then, the custom intake was installed. Now, keep in mind, NONE of the tuning has been done, nor have the heat shields been put in place (so the car was running about 15° over what it did with the stock airboxes) but it still picked up an extra (Mustang) 13RWHP. It did 435RWHP which corrects to 461RWHP. Once tuning is done and everything is dialed in, there’s a real shot at 490-500RWHP and it sounds amazing!

You probably remember his straight piped Murcielago.

After David had owned his LP670-4 SV for all of 30 minutes, he had it on the dyno for its first AWD run. We did 3rd and 4th gear pulls and managed 595 and 585 AWHP respectively. We then did the best modification that you can do to ANY Murcielago; we made it RWD. By removing the front differential, half-shafts, and torque tube, we not only removed 125lbs. but we picked up an additional 20WHP. In addition, we removed the secondary cats and muffler for an additional weight savings of 89lbs. This gives us the baseline for our epic lambo build where Stig will be adding around 1,000 MORE RWHP. Stay tuned for more updates!
