Today, 12:15 AMm54b25 commented on article Porsche 911 Turbo S (997.2) versus McLaren MP4-12C head to head at the 1/4 mile drag strip in Porsche Blog, Performance, Tuning, Motorsport, and Modification NewsThe 5 ultra rare HIGH SPORT edition sold thru THE COLLECTION in Coral Gables, FL dealer...with some convincing customer to McLaren Special Operations division. Will be very close to low 10's & possible high 9's if you can find an owner or McLaren willing to send a HS for PBIR runs. Also, the 2012 MP4-12c software upgrade 616bhp everyone looks at the peak 25 bhp gain alone; an axial dyno (unless you have a McLaren Tablet to use a 2wd dyno =) will show you the under the curve useable powerband to be much higher than the peak 25bhp gained. Also, note the engineers redid transmission software as well & that adds a difference too!!! BTW, that Dragtimes McLaren have the optional McLaren INCONEL stealth exhaust... I don't think another exhaust will make a difference.20 replies | 330 view(s)

They look to perform about like RB to me. The real issue with ASR isn't their N54 turbos its everything else with the business including the ownership. :)358 replies | 17616 view(s)

Factor in the unkowns for strength and 5-6 psi is a realistic conservative fully backed package160 replies | 1077 view(s)

I mean, ESS was the mainstream option until Gintani released their kit (late last year?) Tried Googling', not a single tech spec has been released on the 1740 -- No compressor maps of CFM. It seems everything people know is word of mouth at this time, like Sticky estimating 5.5psi160 replies | 1077 view(s)

People are making the same mistake on M3Post, you cannot directly compare a Centri Blower & a Roots/Twin Screw. They're going to have completely different curves & offer completely different power bands. IF there was a larger Roots blower that could be adapted to the S65 & offer the same peak power as the V3, then it'd easily be the better option with instant boost & better low end TQ.160 replies | 1077 view(s)
