Last Wednesday, Feb 2, was opening day for the 05 season at Sacramento
Raceway. Two '05 Mustang GT's showed up, and everyone was interested to see
what they could do. Both cars had 5-speeds. They both ran pretty consistent
between 14.25 and 14.50. The best time I saw all night for either car was
14.24, and that was with almost no wheel-spin off the line. I would have
thought it would run about the same as an LT1 powered fourth gen. The
horsepower and weight are about the same. The whole crowd agreed they were
I would have expected them to be running around the 13.60 to 13.90 range. I
guess 14.20s isn't real bad. Actually thats all "pure-stock" LT1s are good
for...... and even better than stock Iron and Aluminum headed L98s which is
good for 14.80s to 15.20s in the IROC and mid 14s in the Vette..............
<1993 saw the debut of the fourth-generation F-body, and a marked
increase in performance. Camaros and Firebirds received a version of the 5.7
liter LT1 engine from the Corvette. This "Gen-II" small-block featured
aluminum heads, reverse-flow cooling, and a redesigned intake setup that
made good power all the way to the engine's 5800 rpm redline. The 1993 LT1
was rated at 275-horsepower, and LT1-powered F-bodies were good for low-14's
at the strip.>
Just a little LT1 clip from the year one website about the LT1 #s.....
I'm running a '96 LT1 powered Z28 with a 6-speed myself. So far my best time
has been 13.85@103mph. The car is basically stock except it has a Flowmaster
muffler with stock pipes and SLP's light weight flywheel.
There was another guy out there with a showroom stock '04 Mach 1 with an
automatic. The Mach 1 was only rated at 5hp more than the '05 GT. He would
just leave it in drive and step on the gas. He ran mid 13's all night.
There is nothing wrong with low 14s from the factory..... Add K&N filter and
a decent cat-back exhaust should break them into the upper 13 range. IMO
that is VERY good for a street car....... I'd say the new Stang is a good
match up for the LT1 Z-28s.
Now, we all know the LS1 is a whole different animal.
Wasn't the OHC a step up from the 5.0 pushrod?
====================================Yes.... and they tach alot high too. I don't think Ford even produces a
pushrod engine anymore.
anyway, the 5.0 Mustang was a low 15 second car.... some would run high 14s,
and some of the lighter coupes (trunk edition cars) could hit mid 14s (14.4
...and the 1985 GTs had awesome 60' times...
....and an added note on the 4.6.... The '96-'98 had the restrictive head
design, and the performance wasn't much to brag about, but the '99 and later
had the good heads and those 4.6 GT Mustangs are pretty impressive....
(still no match for the LS1 though)
I think the '99 and later 4.6 is rated at 265 hp? (somewhere around that)
and the new retro styled Mustang is 285 hp (correct me if I'm wrong)
...and the 5.0 Mustang was only factory rated at 225 hp... but the 5.0s
pushrod design, factory roller cam and tubular headers made loads of torque
out of the box....
I think that there are two different style heads for the GT cars. One
for the N/A and one for the supercharged cars. I had an opportunity
to buy a factory supercharger from a 04' SVT Cobra but research says
that I would have to have replaced the heads to make it work.
68' Camaro RS
88' Firebird Formula
00' Mustang GT Vert
Well, in theory, yeah...but since I haven't actually driven one (I'm
waiting for the Coupe to come out before I take the new 'Stangs "that
seriously") I won't have any personal road test info to go on. ;)
Dealers always wonder why I ask them if the car's been warmed up before I
take it for a test run...if they only knew. ;)
