I see the 928 as a possible drag racer.

It's no heavry than a Cammaro, or Corvette. The S4, GT, and GTS engine put out more than respectable amounts of power to any stock car out there, expecaly the age of said cars. And a respectable amount of torque.

The rear mounted tranny also means that the driveing tires have superor grip.

Will the 928 do great in turns, high speeds, and other things? Heck yea. but if you wanted to go fast in the straight line, it'll do that too.

Jim,

Perhaps it was not intended to read the way it did, but that was the way it read to me. Regardless, truce, or whatever is appropriate. BTW- If that looked like a rant, I would hate to see what you think of my rants.

Meanwhile, back at the drags...

Danny's car is definately one way to go, and looks like neat work. I would be interested to see someone actually wring out a factory 5L 4V and see what can be done when you can take MTBF and driveability concerns off the table - maybe beat those flippin' Supras. 1000+ HP shouldn't be a serious engineering challenge (only 200BHP/L) in context (lotsa boost, serious fuel delivery upgrade), though I would have some concerns at that level with the driveline - nothing that couldn't be worked around though. Anybody heading in that direction?

It would sure be interesting to see, but whoever does it has some work ahead of them to beat some of those Supra guys. The quickest 1/4 mile for a street supra I've seen documented is 9.001 seconds at 153.71mph. That's in one that's described as "100% Street Trim Full Weight Supra - Driven to track with A/C on!!" There's a national Supra event in Texas coming up in two weeks. Maybe a faster time yet during that event?

Steve,

Impressive, though I guess, not surprising, since the semi-hardcore Supra guys (no a/c, interior stripped) are in the mid-low 8 sec range IIRC.

Of course, when Dodge Minivans run in the low 12's (for under $1000 in hop-up parts!), somebody just got an all-motor Honda in the 9's, the turbo Saturns are in the 8's, I would imagine the not-so-legal Supra crowd will be getting to the low 7's/high 6's soon, if they aren't there already (just don't follow it that closely). The straight 6 is a great config, and that Toyota bottom-end seems to be just about bullet-proof.

Should be entertaining reading after it happens. If you get to go, do keep us posted.

Didn't get a chance to go, and didn't hear of any of the drag strip results yet. There were a couple of Supras that did over 1,000rwhp on the dyno, with the higheest being 1131.6rwhp. The highest dyno numbers of the day were from a street Viper with a centrifugal supercharger. Can't say exactly how much power it was making though, since the dyno can only measure up to 1,200 at the wheels. It maxed out the dyno with 1,200rwft/lbs at 3,700 RPM, and 1,200rwhp at 5,700 RPM. Apparently the centrifugal blower setups are starting to get more common on street Vipers, with cars like that running in the 9s in the quarter mile.

This site had some info/videos on fast supras. They're great and all... but these guys have to put an awful lot of money into the motors to see those massive numbers.

The Vipers will be really scary when people start actually getting some output from them. Yeah, 1200+ is an impressive raw number, but not from 500 cubes.

They are some things that are far less than optimal about the setup, but nothing that can't be fixed.

It's only a matter of time (and cubic$) before somebody breaks the 2000 RWHP number with one of them, with a streetable app. Eek.

Prices for power increases on the Supras don't seem to bad to me at all.

That's definitely true when you compare it based on hp/liter. Neither the clock at the finish line or the dyno ask how much displacement you have though.

2V4V

No disagreement, I was merely alluding to the development potential that exists with that much displacement - though it is a V10 config, and they have certain inherent limitations compared to a V8 or, even better, V12. Just saying there's a lot left on the table yet.

I would tend to agree that Supra performance is not all that expensive, esp. if you factor in a lot of the high dollar guys are 'checkbook tuners' - they spend a lot of their performance dollar having other guys do the R&D and installs, and builds. Not all of them of course, but more than a few that I've met couldn't swap intake manifolds to save their lives, let alone build an engine. (They can do bitchin' stereo installs though...) Oh well, somebody's got to keep shops in business.
