For those hating on IRS, how bout a 8.75 @ 168 Viper?

A feature in the May '05 Hot Rod magazine covers a twin-turbo 510 ci
Viper running that number: 8.75 @ 168. Based on trap speed, the
builder estimates 1,600 hp. That's with no intercooler! The guy added
Aldan adjustable coil-overs, a 2.73 gear, a Quaiffe lsd (a torsen?),
and 35-spline halfshafts, and runs 28-12 x 16 slicks at the drags, but
the 6-spd and IRS are as-delivered.

Besides all that, the car is street driven, runs cool, it's got a full
interior, functional A/C, and a stereo with 5-channel amp and a
sub-woofer.

I think the fastest Viper in the U.S. today runs a crate Hemi
instead of the V10.

Ok.. wait a minute. New gears, new half shafts, and a new differential.
What about that IRS is as-delivered? The housing? Maybe a bearing or two?
New coil-overs holding it down to boot. That's like the DSM guys saying
that the stock transmission can handle 9's. There's nothing original inside
the housing.

Yeah, it can be made to hold that kind of power, but the cost to do that on
a stock car is extreme, and Ford didn't want to jack the price of the car up
into Corvette territory to do it. They know people are going to modify the
car - why get themselves into legal battles with people who upped the boost,
broke a half-shaft, and slid into a wall because of it?

I wish they would stick with the IRS too, but the devil's advocate side of
me can understand why they would run from it.

So more dumbing down for the moron majority.

I doubt if a stock 8.8" could handle 1600 hp, a pedal clutch, and a 12"
slick either. The reason I posted about the 8-second Viper is to show
an example of an IRS working at the dragstrip at such a high level of
performance. It's the most commonly-cited rap on IRS -- Team Mustang
made it when it intro'd the '05 -- that it's no good for the dragstrip.

I'm not quite sure of the logic, that Ford chose to go with a solid
axle because a drag racer who popped a half-shaft on an IRS GT500 and
put his car into a wall could argue that a solid axle would not have
done this. That does not seem like a very good plaintiff's case.

I too can understand why they chose not to go with IRS on the GT500.
The reasons are (1) the expense and (2) they will not sell one fewer
GT500 without it than they would have done with it. Basic bean counter
logic.

An IRS can work perfectly well at the drag strip if it was designed
properly. How many Ford 9" rears could be bought for the cost of the
Viper's IRS setup? ;) IMO, the Mustang doesn't have an IRS because of
cost and most Mustang buyers either prefer a solid axle or don't care
one way or the other. Personally, I hope the GT500 comes with a 9"
rear. It would handle about any amount of power the blown 5.4L could
muster.

The same goes for the GT. The Mustang's success has always been the
result of the bang-for-the-buck it brings to the buyer. If Ford ever
forgets this the Mustang is doomed. Helping to keep the car affordable
by using a solid axle tells me they still know us Mustang buyers fairly
well. I expect the IRS will show up in a few years though.

Slight change of subject, but on Car & Driver TV the past two weekends
they've show footage of a bright yellow Mustang GT doing a huge smoky
burnout. That thing is an INCREDIBLE bargain for $25,000 (or it WILL
be, when they start having some sitting on the lots at that price).

I saw that too. I can't remember the C/D guy's name but he seemed to
really like the new Mustang. They said they were going to doing a
segment on the GT. Do you know if it aired this weekend?

Two weekends ago the whole show was on the Ten Best awards. The Stang
was a winner and they showed the burnout -- on a public road no less
-- as part of the Stang Story. This past weekend the story was a road
test story on the Mustang GT alone, and they showed the same footage.
And I have seen another edition of the show where they run "THE" GT
against a Porsche 911 and a Ferrari Modena. (The GT comes out on top.)

We're going to have continuing confusion over this, that both of the
two hottest Fords can be referred to as "GT."

After you run 8.something one time you won't be allowed to continue
at an NHRA sanctioned track. The max for an IRS rear is way up there
like 11's or 12's I think, but surely no lower than 10's
