There's a Roush Mustanf in my town, not sure of the year, but it's the newer Mustang body style. What's it got in it, and would a modded LT1 take it ya think? Also, there's a few Saleens at school...how much different are they than Roushes? Thanks,

 

There are three stages of the roush. Stage one is just appearance and stage two is exhaust intake and a few other goodies. The stage three is all of the above plus a super charger. they make 380 horse and are fairly wuick. A little quicker than a stock LS1 but slower than the new 03 cobra. If the LT1 is modded it will destroy stages 1 and 2 and will give stage 3 a run if it has at least a cam

 

theyre suppose to be quick. a saleen depending on which stage but normally stage for stage will beat a roush but id rather get a steeda package

 

The Roush also in Stage 3 form is given a bunch of handling things..like sway bars, springs and such. This makes launching them virtually impossible. If the kid is an idiot, go for it what you got to lose, he has a supercharger and paid ALOT more money.
I'd stay away from the saleens the S281 is a real bear

 

The saleens are in a whole other ball game and pack the punch. The roush cars look and sound incredible with the side exit exahust but aren't real competitors. Funny to read on LS1.com and camaroz28.com about all the stock LT1 and LS1 guys laying the smack on the 40K fords.

 

My uncle has a Roush Stage 1, which has appearence mods and side exhaust. Absolutely gorgeous car and a nice exhaust note with the side exit exhaust (too quiet for my taste though).

As far as power, I was not impressed by the car, I'm sure it runs whatever a stock GT runs. My stock LS1 could destroy it.

The most powerful are the supercharged Stage 3's, which ran 12.9 @ 111 for Car and Driver.

Price as tested: $50,558 (base price: $40,704)
Engine type: supercharged and intercooled SOHC 16-valve V-8, iron block and aluminum heads, Ford EEC-V/Roush engine-control system with port fuel injection
Displacement 281 cu in, 4601cc
Power (SAE net) 360 bhp @ 5250 rpm
Torque (SAE net) 375 lb-ft @ 3000 rpm
Transmission 5-speed manual
Zero to 60 mph 4.3 sec
Street start, 5-60 mph 4.7 sec
Standing 1/4-mile 12.9 sec @ 111 mph
Top speed (drag limited) 164 mph
C/D-observed fuel economy 13 mpg

A lightly modded LS1 could beat 12.9 @ 111. And it wouldn't take a whole lot for an LT1 either, maybe bolt-ons and a decent cam.

 

Found info. about Saleens right from their site:

Saleen S281 Coupe
14.0*/99.0
$36,629

Saleen S281 Supercharged Coupe
13.0*/108.0
$42,322

Saleen S281 Extreme Coupe
12.5*/113
$61,120

 

Yup, I took a supercharged S281, haha didnt get to race that long though (first and maybe a split second of second)...

That race cost me though, $110 and 90 days probation...

 

Those are all on crappy street tires, I've seen 11 second times for the S-281E with better driver and slicks. I would hope that a regular S281 SC could run better than those times thouh, I am faster with my car than that time! But, again, regular street tires makes it hard with all the lowend torque.

 

I raced a s281E a while back...wasnt pretty, but stage 1 and 2 roushs' are easy

 

Its probably just has the Roush body kit, thats what you will run in too 99% of the time. Same with the Saleens. A bolt-on LT1 or LS1 would run with it easily.

 

becareful though. i raced what i thought was just a stage 1 roush turns out it had saleen sc on it with some steeda stuff. i was in the camino and he kept up through 3rd and then he just blew right by. if i was in teh maro it wouldnt have been fun. old man driving it too. nice too

 

I used to work with a guy that had a roush stage 1 mustang.. It had a 3.8L v6 with manual trans...

 

doest saleen make a s351

 

I thought they were all v8's

 

Saleen made an S-351 but not too many own them. Needless to say they were rare and FAST. Dynoed near 500 rwhp stock, but cost way too much.

 

I saw on car&driver a new roush stage 3. had a 4.6 with better exhaust, intake, t/b, and a roots type supercharger. They said it ran a 12.3 @111. w/380hp(crank). Does this sound right? If that's true, does GM got a car that can hang with these Stage 3's and Saleen S281's?

 

Did C&D really get a 12.3 @ 111 mph out of it? That seems like a pretty low ET for the MPH for Car and Driver to get on stock tires. I know 12.3 @ 111 is VERY doable, but I've never seen them get such a low ET out of a mph like that.

Ford doesn't really make those cars, aftermarket tuners do (Roush and Saleen). As for GM itself making a car to compete, the ZO6 runs better than 111 mph. I've seen bone stock ZO6 vettes run 12.4-12.5 @ 115-116 at Milan (crappy track) on stock tires.

 

The mph did seem low for the 12.3 especially fron C&D or any other mag where they dont get the best times out of cars. And yes a Z06 should hang with or outrun one of those, I am not a huge fan of the tuner or whatever you call them...

 

I just saw it again to confirm and that's what they said, I thought you would need more than 380 bhp to get low 12's, (someone check me on that) maybe that's without the options though? If it makes a difference, they had mario andretti driving it, it had a black hood(I didn't notice that on previous models), and they said they had a magnaflow cat-back on it. I didn't have dr's either just bfg street radials. BuckeyeROC, you have a fast car, how much hp does your iroc have?

 

It makes a difference to me when Mario Andretti is driving over some magazine editor. THAT explains how it ran 12.3 @ 111 on street tires (damn that's good driving). I bet it would have went high 12's at about the same MPH w/ a mag editor in it. Not to take anything away from the car, it's putting down some good numbers.

No idea how much HP I have. My guess is I have a raceweight of 3600-3650 lbs. It's a fully optioned 89 IROC, with a/c, power everything, etc still. Only things that would really reduce weight would be aluminum heads, front sway bar currently off, fiberglass hood (not much lighter than stock), and I took the radio out. But I added Spohn subframe connectors, so that negates some of it. Also add 280 lbs for the driver. Like I said, I'm guessing around 3600-3650 raceweight. Anyone have a decent HP calc???

My HP guess is about 400 HP at the crank, and a bit over 400 ft/lbs of TQ.
