Congrats, great results!

The pic of the 911GTR really puts things into perspective!

Great result Eddie, well done.

Couldn't make this one as too much track action recently with Oulton last week & the Ring in 3 weeks, needed to make sure discs & pads have sufficient life.

Ben, the straight is much longer than 1mile. IIRC it's over 2miles but the timing beams are at roughly 1.6miles.

Steve, what was your max trap speed? IIRC I was getting 203 on the speedo when hitting a true 197 through the trap at the last VMAX.

Things is with both cars there more in there....I know I could do better with a few more runs....next time!

Steve, honestly their is next to nothing in it as the bottom bend exit speed/style would only improve trap speeds by 1-2mph at best.

I've run both lanes & many different angles of attack so many times, only to see no benefit or minimal by the time you reach the speeds traps.

To give you an idea, a standing start from the bottom of the main runway equals about a 3-4mph reduction in trap speeds.

I doubt without many further mods or severe weight loss I could get my best speed any higher than 197 & as you'll have found, heat soak is a killer & you need to get the fastest runs in early on.

Impressive stuff but does it beat a TTRS 30-130

The frontal area is a huge disadvantage and just shows how important getting that CD rating as low as possible needed to be.

That said, its a direct relaltionship, CdA, so assuming 10-15% bigger area, what's the numerical difference in the Cd rating between the Nissan and the latest 911?

BenLinney@GTC · 5th September 2011, 10:40 AM

yup agreed wish the 35 was bit smaller

results here, some dam fast porkers VMax Hammer Results

Not sure on the trap speed...passenger was not paying attention holding the camera but would suspect 196mph. You were doing really well to get 203mph indicated as that's what Eddie managed the last time with his 750!

I know what you mean re heat soak etc....next time I am not going to blast to the bottom to keep the temps down from normal running temp, go wide and cut in and see what the car will do....I do think I could get 1/2mph more but that would be it without significant more investment.

thistle · 5th September 2011, 12:08 PM

I think I could thread that Porker easier down the narrow lanes. And they do ride nice and comfy

Charles Charlie will tell me off for being soft again.

Nissan claim a far better Cd than Porsche (0.26 vs 0.31-0.34 depending on model GT3/Turbo/GT2 etc) , but the Sport-Auto wind tunnel results don't back this up. They tested the R35 at 0.31 from memory.

The fact that a 997 GT3 with 415hp has the exact same claimed 193mph top speed as a GTR with 480 (really 500), backs up that the Porkers have a lower CdA.

thistle · 5th September 2011, 02:35 PM

Engine speed at peak power and engine speed at top speed along with different drivetrain layout can make a CdA comparison based on top speed difficult.
