How does anyone downvote this thread

The t.50 is so amazing but that fan ruins the rear aesthetic imo. I love function over form design on these cars but the fan is brutal.
While I definitely get your point if Gordon Murray tells me a car needs I LOVE AGGIE FOOTBALL painted over a Gay Pride flag on the hood then that's the way I would drive it. In reality, I have always loved the Brabham BT46 so I think the fan duct is rather cool, but it is the view most other drivers would see. I do love how Murray can build a hyper car without all the wings, flaps, and spoilers. I expect these T.50s will be selling for HUGE money in a few years.

I’ve been wondering the same thing

Probably due to running out of road. At an average of 165 mph, you cover the 7 mile stretch in 2 min 30 sec approximately. Took him 1:10 to get up to 331, so if he backed it down at the same rate, he was running out of road.

Shmee150 with a great breakdown.
Watching this and several other videos I think the 331 number is serious bullshite.
Whether or not it is valid I have long seen SSC like Hennesey I will believe the claims when they are third party verified and will believe the car is actually a production car when customers start taking delivery.

I think it might be on TopGear for some funky video editing for production value. Reading the interviews with Webb, some of the events, emotions, etc. that he described aren't seen in the alleged record breaking footage. I would think that they have to do 3rd party validation now. Hopefully it comes out soon.

How fast does it go in Baton Rouge traffic?

They would have had to slow the footage down by about 15%.

That is really the only option at this point, otherwise I don't think it will be accepted unless there is a good verifiable reason for the serious discrepancies.
I would like to have the Cd number and frontal area to see if 1750hp is enough. It would have to be a lot slipperier than the Chiron SS to get ~30mph more Vmax with only 150 more hp.

No, the rumor I’m hearing is that they used a different run for the final edited video. They made quite a few building up the speed as you could imagine. But like I said it’s just a rumor at the moment.

I’ve only seen the drag coefficient published at .279 and weight of 2750 dry. I’m also curious if the 1750 is with pump E85(65-75) or real E85. I assume the latter.

Pretty sure the designer said it was E85 on the podcast I linked earlier in this thread.

It’s gotta be the kind you get out of a drum not a pump.
Posted on 10/27/20 at 8:02 pm to billjamin
Is it an issue if the fuel came out of a drum?
Posted on 10/27/20 at 8:09 pm to NewIberiaHaircut
No but it’s context when it’s not something that’s really easy to get. It’s no different that using C10 at that point.
Posted on 10/27/20 at 8:17 pm to billjamin
You can't just order true E85 from VP Racing? I truly don't know but it can't be that hard to get, can it?
Posted on 10/27/20 at 8:27 pm to NewIberiaHaircut
Idk about VP specifically but Sunoco makes it amung others. I have 15 gallons of E98 in my garage right now. But then you have to store fuel in your garage, transport it, possibly have a way to unload a 55 gallon drum, pump it, etc. It also expensive, E85R is about $500 a drum last time I got it. Not that anyone with a $1M+ car would car about that.
The reason I always wonder is because it’s become cool among boutique manufacturers to quote E85 numbers rather than C10, 16 or something because people see E85 and think they can get it at Kroger (which is actually where I buy mine most of the time). But the reality is they’re producing those numbers on what’s essentially race gas. It’s really just a marketing tactic in my opinion.

I understand the top speed run looked like it was a wild ride (due to wind) and I suppose no one wants to put that video out since the 'Segg and Chiron looked completely settled. My problem with this is why does the laptop n the floorboard mirror the actual numbers on the large display on the video? There is some frickery afoot here and they should have known the scrutiny would be on them especially for a jump as big as they relayed.

The Chiron SS300 was modified and where the top speed mode of the standard car is .35 the power balance formula has the Vmax run car at about .285 with a frontal area of roughly 22.5 ft^2. I would need a good head on shot and something for reference like the front tire width to estimate the frontal area of the Tautara. I just took a few minutes and get a rough frontal area of 19.75'.
I did a rough use of the power balance formula using 1750 hp .279 Cd and 19.75 square feet frontal area some educated guesses at rolling resistance (using the 98 degrees I saw listed for ambient) 32 psi for tire pressure and the contact patches derived from the PSC2 tires of the correct width and assuming 60/40 rear weight bias. I estimated drive train losses at a conservative 12.5% and no incline on the road, despite the fact the road isn't flat it was a two-way run.
Plop all that in the formula and I get a Vmax of around 295 mph. Now I can usually get down to +/- 1% on Vmax if I have all the exact numbers but here I am only comfortable saying I am +/- 5% though I have tried to err giving SSC the benefit. This puts the 316 number in the realm of believability for me but given the odd things like possibly showing the wrong run, blurring the speedo, and the laptop showing the recorded speed I am going to need some independent verification.

I was blown away when Murray said/implied that they weren't completely sold out yet.
Like that is an easy money maker if you can get your hands on one.
Obviously Murray isn't going to sell to someone who wants to flip it, but still shocking it wasn't completely sold out.

Don't disagree but the LM spec F1 is tGOAT
