Besides Toby, it's not just about the straight-line speed, but the technological leap that this kind of motor build represents for the entire community.
I think this point sums it up, as seen with Supras, the knowledge that these guys gain as they continue to push the boundaries of their cars will filter down to grass roots (relatively) with more modest performance than these Texas milers for fast road/trackday use. Everyone wins imo.

You're obviously not very good at reading then because there's more technical information in the one post regarding the engine build, than I have seen on this site in the past year combined. And if you had read, you would know that they're using EVOMS intercoolers - the same ones i used last year to keep down temps. Must not be too bad then huh.
I saw they said they used EVOMS intercoolers and if YOU bothered to read more accurately you would see they said they had to make even bigger ones - so as usual you miss the detail and get it wrong, but hey this is the internet and you are a "guru" smile

If you would be so kind as to ask on that site whether they used ice/C02 or any other method for IAT reduction you may find that your intercoolers bare no resemblance to the methods they employed for that devastating run.... If you developed (or borrowed from me wink ) an ounce of cynicism you might decide that EVO (that is who did the engine right ?) have put together an explodamotor to get all the headlines which are raved about by a lot of non technically minded people and then sell their 750hp/750ftlb packages (off the back of their demonstrated technical abilities) which in reality perform little better than 600hp/550ftlb packages...... - I mean you think you have the same intercooling which was on that car for that run laugh

Well I for one am just glad we live in a world where people are still prepared to invest the time and effort it takes to do this sort of thing. smile

Arguing about the relevance of this engine build is a bit like all the tree huggers who argue there is no need for cars that can exceed the speed limit. There may be some logic to the argument, but sometimes fun trumps logic!

2 bar and race gas from what I could read, with extra head clamping force. Not cutting edge in my book (no offence intended), building the package is the difficult part and they seem to have done a pretty good job given their goals. I would like to see what eddies car would do with 996 areo, wouldn't surprise me to see it come close as the 996 is a very slippy package.

I think my new engine will be a first for the technology we are using, but will be built with more street focus and I don't think i'll run 2bar smile

If anyone wants to build a 911 drag car, my old engine would make a good base with only the need to add another gt4088r to the package to get 1000bhp...

FYI Eddie ran a 996TT at last years event (RPM shop car - where he works). Went 191mph, and up until October was the fastest water-cooled Porsche to run the Mile (VR Alex then ran 211mph running ungodly amounts of boost with his welded on heads).

Eddie chose to use the 964 body for his platform because it is narrow and therefore more aero at those kinds of speeds. He has stated this on numerious occasions.

But doesn't he run 996/7 head lamps or something weird ( one of the rennlist guys did a similar thing DIY which was pretty brave). I always thought the 996 had much better areo than the early models even comparing wide vrse narrow due to windscreen rake.

I think one of the problem the guy will have is head studs pulling out of the case at those tq levels even with larger bore bolts. Someone tried that in the UK and it didn't last that long ~3k miles whistle.

We have a very trick sealing method which we hope to showcase on my build, but i'm not going for big boost, more to show efficiency as I can't afford another engine smile

Do you know what fuel was being used, I guess it must be 115 or close. You can run a lot more timing at that mixture, about 4deg IIRC.

Yeah, he has 997 headlights on it. I don't know so much about aerodynamics at those kind of speeds, but considering that he built the thing from the ground up for the sole purpose of running the Mile, and had his choice of any platform to use, I think he did his homework. wink

If you want to see a truly bleeding edge Porsche build, look at this from CJV: http://www.6speedonline.com/forums/tuning-modifica...
(caution: it's 70pages long - work from the most recent back a few pages and you'll find the build summary - it's truly staggering the time he has put into documenting every technical detail of the build)

He's done everything you can think of - o-ringed heads, custom everything, knife-edged and thermal coating everywhere, custom NASCAR-type bearings, stroked to 4.6L, etc etc. This has been a 3yr build (due to the amount of unique custom parts required, and his budget), and the car will be an absolute ANIMAL - we're probably talking about 1500rwhp at relatively conservative boost levels. Will be interesting to see, and it's in the final stages of the build now. thumbup

how the fvck is that even remotely possible in a road car? just getting the traction to do that is an achievement. awesome!

has anyone worked out the real rwhp from the acceleration data?

Footage of the run.... incredible....

Best bit at the end when the guy asks "what you think you did" and driver replies like he'd just tootled down to the shops calm and cool as you like "two thirty"

Just read those build threads on 6Speed...

WOW! I really, really want a long stroke crank now!

Very interesting stuff and definitely more technical than PH, enjoyed it very much!

Not that I don't enjoy being here, I love it here... Just like this boundary pushing tech stuff every now and then!

4.5 litres! Wow!

Even though this 996 is 2wd he's got a massive traction advantage over the Supras and Vipers, both of which realy struggle for traction until 130+. The engine over the back wheels really helps with traction. Would be interesting to see datalog traces overlaid for the various cars.

Here is the 0-300kph posted on RL for this car - not proper traction until 200kph.....

I agree. What is most striking to me about the video is that the run seems so smooth and effortless. It's like he's out for a Sunday drive. Unbelievable.

Here's an 18sec 0-300kph Porsche racecar. Notice the contrast. This guy is fighting the car the whole way, and Joe's car is way way more powerful: http://www.youtube.com/watch?v=fC7Oz...eature=rela...

The 996TT is going to be the platform to have for performance the next few years, after these recent developments. Wouldn't be surprised to see used prices start to firm up... well maybe not over there where apparently there isn't much use for power. wink
