I'm just starting to relearn my car now that its running on motec and never cease to be impressed at how far these aftermarket builds are past the cream of manufacturer crop.Just dawned on me too that you blew by the top speed of a RUF CTR... in 1/2 a mile. RUF should probably call Emre themselves .
Thanks, man! Yeah, we are punching above our weight.
Yes, I don't think most people understand how good Emre is. Not just at making high power, but all of the little details. Car making tons of power, putting it down and logs are super clean. Also have to give props to the boyz at AIM for the setup of the car. Suspension and ride height are perfect. Great tire advice, etc.

Best wishes with you car!

I would expect to see some evidence of “struggling” when acceleration is greater than ~1G (on treaded street tires) below 80-ish mph when aero downforce starts to matter. But, in your graph, above that there’s still very significant variation in display acceleration which I would not expect to see.
I have no idea. I am no Dragy expert. I just turn it on and run.
Was not struggling for traction that much. Emre has it running near the limits of traction but car felt planted on this pass.

Nice post.

Thank you, Jay. Yes, that's true. Definitely helps/is necessary.

Nice. Yes, was a drama-free pass.

Fair’nough.

Looking at your last screenshot posted above:

Is it shifting at about 140 mph and again at about 180 mph?

Yes. You can see that in the video I posted above (in-car cam).

Killing it as usual Dave. Bartending the parking lot on Friday, 220 passes on Saturday.

Yeah its the shifts, watch the video goes into 5th at around 145, 6th right around 180.

The noise is the acceleration graph, dips are usually loss of traction and shifts even a fast shifting pdk will have a dip, a manual car will have an even bigger dip . The car makes 1500whp, probably even a little more to go 220 and is making a pass on an unprepped surface thats anything but smooth and has dips, ruts, ect.

They went 260+ and have the overall 1/2 mile record, I think their slowest car this weekend went 240. They literally dont care.

I get what you're saying with the resources poured into those UGRs, which are amazing in their own right, but not sure 40+mph behind is 'spanking'... As long as they're both doing the 1/2 mile which I think they are. My track tech has a UGR Gallardo which I've ridden in and it's something to experience first-hand.

Either way, congrats to anyone setting new records, this will be a fun video to watch during lunch!
This, when it comes to 1/2 stuff the lambo will always be king. Especially the STO , the aero, the traction and not just power. The one other lambo from horsepower lounge did go 251 so other shops are figuring it out . The v10 platform will always be king.

Thanks, Arkady. LOL Those Map 8 Margaritas are popular.

Agreed overall, the 10s dimensions being derived from vw manufacturing setups for turbo motors can't hurt but I think you hit the nail on the head far as traction. Its not a power game as much as a grip game at these levels and down force is mechanically free grip. Financially free it is not... While Emres built products aren't exactly cheap, they don't cost you a corporate exit to complete. Dollar for dollar, cylinder for cylinder, or by most other proportional measures; this seems a hell of a lot more efficient. My personal experience with aim aside, owners on this forum seem to have very daily-able cars posting these numbers from their builds which isn't something a v10 is from the factory (drove a 2020 8P for 2mo - great fun if short on torque but insanely impractical). We might not beat them outright when they bring their toys in on a trailer, but we will enjoy defeating the ones in our bracket and driving both there and back home.

Re them not caring - most zombies don't . The V10 is out of the market, making for a finite potential market in which to operate and relegating all R&D to the vintage section. There is no analog replacement so driveline logic, mechanics, and tuning strategies will have to get a lot more advanced to handle the hybrid world. While R8s stand out when we see them outside, the sales numbers were never great and despite all the hyping the huracan sold even less. We're looking at just over 1k/y together in the US if not less (https://www.goodcarbadcar.net/audi-r8-sales-figures/ & https://www.goodcarbadcar.net/audi-r8-sales-figures/). Porsche is very likely to be the last manufacturer standing in the IC motors world given the customer base which to me says that the R&D investment in these platforms is worth it especially as the 992 uses more or less the same motor as us and whatever advancements in tuning/builds are made specific to the flat6 may be useful down the line when the next generation arrives. There are a ton more flat 6 motors sold over the same model years (https://www.goodcarbadcar.net/porsch...sales-figures/). If they're a business designed to make profit and don't care about a shrinking market compared to a larger semi-tapped one... i guess that's their call. IMO, whomever figures out how to properly tap the Porsche one for this stuff (at a level of total packaging/hassle-free ownership which Porsche drivers desire) is going to be able to buy a 959 from the petty cash drawer.

Grew up going to the bonneville salt flats. Has anyone run a turbo on longer courses. What kind of speed would you see if geared for a long course do you think?

The 300zx thing was less 300 than these builds are 991s as I recall and it inherently has a drag coefficient approaching that of a bullet even before all the aero work . Given the cross section we have it would take significantly more power than the slick salt flats bodies to reach those speeds. Tires are another constraint. That said... what would it actually take to max out 7th?

Joe Santos (one of the two owners of AIM Performance) drove a 997 at Johnny Bohmers event at NASA Space Center a few years ago. I was there. We ran on the 3 mile shuttle landing runway. Joe stayed in his 1/2 mile pull and was going to run a mile, but he lifted when the moon roof caught air and ripped off. LOL I believe he got to 142mph or so before lifting and would have gone faster. Not sure how much gear he had left.

Not sure what a 991 would do.
