Is this a case of less is more?

Factory 720 did 0-100 in 5.3 & 144 in 10secs

It's an SBC of about 7litres with twin turbos blowing at approx 6psi developing 800hp (I did know the exact numbers but I have had a few bottles of wine since then).

It is a very neat installation by Clive at Prism with a Ford GT gearbox, additional center fuel tank to give just over 100 litres which I am sure it empties quite quickly with Paul driving.

I think it's had a bit of work since then.
A few weeks ago it was at track and road where it shred a toyo 888 from one of it's wheels at the time they were looking for 1000bhp so they told me.
I'd say that 0-100 time was a bit dissapointing he may be lighting the rear up off the mark and the gearing may not be conducive to a quick 0-100, that said 0-150 in 13 doesn't sound too quick either.

I'd say a 140mph standing quarter inside 11 seconds should be reasonably achievable in an Ult with 700 ish BHP with 150 coming in well short of 12 seconds.(subject to gearing).

Edit to say: Scrub that, just remembered it's an open top car with all the associated drag, so probably not too shabby at all.

its not crap tho is it? :-)
the new gtr skyline is talked about as "supercar beating quick" and will run the 1/4m in the v low 11s or v high tens as std with terminals at about 125mph.
0-100in 6 is still damn quick if its not on a prepped sticky drag strip, brunters is anything but!

Lets put this in perspective, 0-100 in 6 seconds is just quick. Many 'fast' production cars do 0-60 in about 6 don't they, slightly less maybe. So yes this is quick.
But the Can-Am times may be disappointing when compared with its peers, but it doesn't take away from the fact, it is still fast.
Did I mention i mention I think 0-100 in 6 seconds is fast?

Terminal speed is the product of horse power/weight.
Times are really down to conditions and peddler.

Terminal speed is the product of horse power/weight and factors of drag and grip..

your wasting your time at brunters for 0-60 and 0-100 and 1/4 mile.

If you want times a well prepared Avon race park is better than the pod as the pod is slightly uphill. pod usually has better grip due to them preparing the track better and spraying to the 1/8 mile and more. Pod gradiant is a loss of about 0.2s and 3 mph.

If you are comparing apples with apples drag and grip are non consequential.

that was my point, the same car at pod/avon park might run half a second or more quicker to 100mph due to grip and would look a lot faster "on paper". my friends car runs 10.4s and 151mph in the 1/4m @ pod but wouldnt get anywhere near that at brunters.

Shame, this car was a day early for VMax was it not. It could then have got in with the prod cars doing 207+. But I guess it has a stdish GB this allowing 17X?

I tested a bike at Blyton which is the same conditions as brunters. was wheel spinning most of the 1/4 even at 160mph +.

track conditions are everything if you want low et.

oh by the way, a 2200 lb car with 800hp at flywheel will run a 8.6s 1/4 under perfect conditions... allow a bit of time for clunky ultima gear changes!!!

I think the time is very good. What makes the Veyron so good to 100mph is the 4wd and gearbox rather than just the power/weight.

Sorry for not knowing, is the Ford GT gearbox a normal manual shift (not sequential/twin clutch/whatever) ?

Also what gear would the car be in at 100mph?

The factory car isn't 4wd.

The Ford GT box is a normal manual 6 speed and I would guess just changed into 4th as I think the engine only revs to 6500 now to retain reliability.

The 'modern' FGT uses a strong and slick shifting Ricardo gearbox but the overall gearing of the car is very long. The story goes that when the car was first made available to reviewers, Ford wanted them all to turn in excellent 0-60 times. So the car is geared so that you can reach 62 (64?) in first (!). So in a 0-100 setting I believe that can be done in 2nd. I know it sounds ridiculous but the car has lots of torque and as long as the driver resets his/her mental gearing model, it all works. The only reason to use 5th or 6th at reasonable speeds is for noise/fuel savings.
