Don't all the TT setups look similar? I mean there's only enough room to go around...but don't quote me, I'm not the engineer

 

4 or 5 cars have ran in the 6's on a 275 or 315 DR, traps as high as 223 mph. Chris Rini did 6.31 on DOT drag radials as well. The X275 DR cars are all limited to stock style suspension. Keep in mind those cars are built to class rules.

I am just thinking out loud, I think 99.9% of the cars are built to class rules and to drag race only. But I bet those cars with enough hook to run 6's on DR's....... and stock style suspension...... and trap as fast as 223 mph,would be formidable street beasts built outside of the confines of the rules.

A lot of secrecy goes on in the world of street racing, so I imagine no one would be willing to do a fastest street car on the planet competition. However as DivvEx said and I agree 100% its between the GTR, and GTT at this point as far as the fastest " real " street cars. But than again everyones tolerance levels are different as to what they are willing to put up with in a real street car.

 

I didnt see the high Hp Supras dyno, but i do know that the GTR spun on the rollers. Furthermore, the GTR and Supras use different dynos.I understand it to be common knowledge that spinning on the dyno will result in a lower power reading. At its basics, a dyno is an assesment of work based on a rolling simulation of real world force. If a car is spinning, it will not move the rollers with full force resulting in inaccuracy.

Here is a post from the AMS guys that i got from the GTR section

At the end of the day... The car went 159mph with an inaccurate 1069 dyno reading. Only conclusion that i can come up with is that the car makes more than 1069whp and is Damn Fast!

 

I was there. Yes, they used two different dynos. Yes, their were 1400rwhp Supras there that did not spin on the dyno (amazingly). Yes, AMS claimed they were spinning on the dyno, which they might have on the first run. After they stuck 2 guys in the trunk of the car, my group did not witness it spin at all on the 1069 run.

I'm also aware of what AMS posted. However, keep in mind that this car is an Alpha 12, which was supposed to make 200 more HP than their Alpha 10 does. When it only made 1069, they claimed it was due to "spinning".

Regardless, all of the guys that were with me knew that if it was indeed spinning, the trap speeds the next day would tell the story (they would be very high). Unfortunately, it ended up trapping slower than it did when it was only making 980 awhp (same car, 9.1 @ 163 at 980 awhp, link here: http://www.nagtroc.org/forums/index....0&#entry618290 ) If it had actually been making 1200 awhp, it would have been trapping around 170 or so.

I'm not ripping on AMS, as I greatly respect all of their accomplishments to date. But you're confusing the facts by posting inaccurate information.

AMS has already stated they've maxed out the capabilities of the stock ECU. They posted this after the dyno day and drag day:
http://www.nagtroc.org/forums/index.php?showtopic=46567&st=180&p=676255&#entry67 6255

This ECU issue 'may' explain why their Alpha 12 seemed to be down on power during both the dyno day and the drag day, or maybe it doesn't. I really don't know. Since my tuner uses stand-alones for his big-power GT-Rs (and has done so for almost a year), he can't confirm their claim either.

What is known, without any doubt, is regardless of what excuses and/or reasons people use, the car made 1069 on that dyno. Period. It also trapped 159 mph. Period. Right where it should be at that power level.

This is not difficult to understand.

Here's another (and more accurate) conclusion for you. If that car was actually making more than 1069 AWHP, it would have trapped faster than 159...since the same car at only 980 AWHP trapped 163....and a full-weight Switzer car with 975-1000 awhp trapped 160. The dyno results are accurate, if not slightly generous.

All that said; let me borrow a quote from Chris at AMS in the first link I posted. I believe it's very appropriate to this discussion:

 

I own a dyno dynamics as well.

Rubber between the rollers does not indicate wheel spin.

Measuring 1000-1200 whp, with a 4WD car, is easy on dynamics.

Bear in mind the 1069 whp run was not made in shoot out mode, was made out of shoot out mode. So it is less than 1069 whp.

WHy they dont dyno in shoot out mode? In order to multiply the figure of dyno dynamics so that it matches a dyno jet. A dyno dynamics in shoot out mode measures 15 % less than a dyno jet.

AMS has a very fast GTR but also there is the "marketing instinct" with this dyno run.

 

+1. Rep for you....

 

that Busa seems far away from being 300 bhp.

Here is a real 300 bhp BUSA, just compare the speedo of both Busa's.

The rider of the 'busa (Johnvon) claims he had issues with his fuel pump and nitrous the night he raced Peter's car in the video. I can't confim or deny the validity of this, but I was told that he raced another one of the TTGs with the same power as Peter's car 2 nights later and only lost by a car length. This story seems likely as a 317rwhp 'busa will trap over 170 mph and should be a very good race for a monster TTG making 1500 whp up to 170 or so.

Here's his post from supraforums:

 

Thank you for the info, I too was thinking that something was not quite right when I watched the video.

 

No car is in the 6's on 275's... I challenge you to provide one example. All of the 6 second drag radial cars are on 315's. David Hance, Kevin Fiscus, Alex Verettos, Paul Major, Mike Modeste, Joel Greathouse (in John Kolivas car), Todd Berry, Mel Nelson, Dave Hinzman, Dwayne Gutridge, and David Wolfe... current record holder. There may be a few others, but they were all on 315's.

As for the 275... I think Johnny K might still have the record... and it's a few tenths off the 6's.

Maybe 4 out of the folks mentioned above have less than 600 cubes and one of them is in the 500's .

No one probably would if the times are shown...

Believe it or not, there are folks with drag cars/ "real street cars" that believe they could take either out from a roll easily... and win handily! One has even told me that he'll drop the chute on a GTT in it's face!

 

Scott,

I ve started a thread called "60-130 and 1oo-150 @ Texas Mile & TX2K11" over the lambopower.com

was erased.

Re-opened.

was erased.

no comment. big boys dont like to talk about this year's texas events....

 

umm... no all of them don't look the same. It's pretty hard to deny the similarities between the UGR and Titan kits in appearance.

 

I said not to quote me, I'm not the engineer

 

I was thinking that he had made it into the 6's at this point, I knew that most of the DR cars in the 6's were on a 315 DR. Thank you for your input on this I was thinking that there were cars with a good enough setup to beat the GTT's on the street. So your saying that you know of a few "real street cars" that would have no problem with the GTT's? I was really just thinking out loud and wondering how much it would take and what kind of car to build a King of the Streets car.

 

Well, that's their prerogative.
