Extra HP & Torque

[quins90lac]

the only thing horse power is a selling point for dealers . the only thing that matters is torque and how well it puts it to the ground and i think the 4.9s trans could handle 300 hp but the 4.5s how ever could not 4.9s weer a stronger built trans and they are electronically controlled and 4.5s weer vac controlled . look at a 5.0 mustangs hp and look at a 4.9s the mustang has more then we do but yet we can still get them off the line that's cause the torque in a 4.9 is made down low where it counts and not up high like a mustangs

1991 Ford Mustang 5.0
-225 HP
-300 TQ

1991 Cadillac DeVille 4.9
-200HP
-275TQ

I hardly believe that a stock 4.9 deville or even a seville could beat a stock stang off the line. The stang has more hp, more torque, more displacement, and less weight. Need I say more?

[quins90lac]

yeah it is posable i do it its not the best thing for the trans but i only have a 90 and i can still get a 5.0 off the line . look at the TQ curves . thats why 4.9 are a fav to put in a fero cause of the high torque and hp mods you can do to them

[Sevillian273]

A 90 eh? So your beating 5.0s with a 4.5???

[red_ghost]

The 5.0 stang has a lot of aftermarket components that make it a better choice for modding, and not to mention its also rwd. Stock the 5.0 stang isn't that fast either. An LS6 is a better choice for a fiero, but its more money. I have seen an LS7 in a fiero with a G5 transmission. Can't image how fast that would be.

[quins90lac]

yeah my 90 can beat a 5.0 off the line . he might run me down but right off the line the mustang cant make the torque from a dead stop where as like say a 4.9 makes it torque down low and a mustang makes it some where in the middle of the rpm band . now a moded 5.0 could probably have high torque all through the rpm band . and the same would apply for the 4.x engien if we had as many bolt on and after market parts available to us as they do about the only thing we can do to make so serous power is to put a turbo on but then the trans becomes the weakest link and theirs just about nothing we can do about that other then make you own CF disk and molly shims and make the switch for bands to chains and put in a shift kit. now they make a shift kit bout thats about it . you figure in the cost to make all of that its just aint worth it unless you just have money burning a hole in you pocket

a 4.9 Deville with 2.97 gears (Touring Sedan) can run the 0-60 faster then a 270hp '94 Deville Concours, and the 247hp '91 Audi V8.

Still, it's not the fastest car, but it's pretty quick for 200hp. There are such things as performance 4.9s, but they either are very expensive or require alot of custom work.

Look up the ASG 5.0L. It's a modified 4.9 that produces over 290bhp and 320lb-ft of torque (changing the camshaft profile decreases the low end torque). Combine one of those with the external mods you can find on this forum, and you'd have the ulitmate performance Cadillac.

[quins90lac]

yeah ive sean the asg 5.0L i would love to have one in my car but have you sean the price on one of them WOW . when i win the lottery im going to get a 94 deville and get one of them put in lol

Picking on 5.0 Mustangs is not that difficult in a 4.9 DeVille. Picking on 4.6 Mustangs is not that difficult in my DeVille. Picking on pre-96 Cobras is not that hard in my DeVille. Specifications racing never tells the whole story.

You guys who doubt the 4.9 are, apparently, looking for dumb stuff like ceramic plating your throttle body and intake manifold. Do you actually buy that crap? That idea came from the same guy who said a 300hp 4.9 would be "still pretty slow" - Last I checked there was a 300hp 4.9 Fiero doing 12's. Guess that's "pretty slow" to a guy with 500-600lbs of hydraulic and stereo equipment thrown into his car, who is obviously EXTREMELY qualified to comment on performance for the 4.9, especially since he's admitted his engine build is strictly for cosmetics.

Stop buying into silly hype and start reading illumina's posts. Don't read mine because I'll tell you to do dumb shit like rip nearly 500lbs of weight off your 91 Cadillac DeVille and get sponsorships for racing.

If you're talking about picking on a mustang 4.6 in 0-60, that's one thing, but in a quartermile or racign where there are actually turns I would be suprised if you won to the mustang. But I still hardly believe you would win to one even in 0-60. a 4.6 does a 5.5 sec 0-60. What is your deville doing?

I know what the performance of the deville is before I had anything done to it. Wasn't that fast. I also say its pretty slow because by comparison my daily has around 400 hp and 400 ft/lbs of torque, and an around 5 second 0-60 plus a hell of a lot better handling than a deville. I don't even really consider that all that fast in comparison to some of the modded Infinitis and any M-class bmw or mercedes AMG. Plus comparing a deville to a fiero with the same engine is silly. Theres a 1000 lb difference. I would seriously doubt any deville would be running a 12. But whatever floats your boat. Hop back in your deville and think you're fast.

[Rodya234]

I could imagine a well modded Deville (>300bhp) pulling out mid to low 13's, but only with Touring Sedan gearing. (which you could install on a base Deville for about $50.)

The Touring Sedan was really the perfect car of that class, handled like a Audi V8, had pretty spirited acceleration, and still maintained comfort and class. It's my dream to retrofit my Deville to a D.T.S. and as its looking right now, it wouldn't be hard to pull off.

Plus have you taken into consideration the weight difference of a deville and fiero? Theres a 1000 lbs difference. I would seriously doubt any deville would be running a 12.

And what exactly is your daily driver? And by the way, your idea of "alot better handling than a DeVille" is skewed, considering the ridiculous shit you've done to your car to make it handle much worse than stock. The weight difference between a Fiero and a DeVille is not 1,000lbs, unless you toss stupid shit like a half dozen 50lb batteries, hydraulic pumps, and big speakers in your car. My DeVille weighs less than the new Z06. Your DeVille weighs more than the new Hummer. See the difference there? My DeVille is sponsored for racing (you know, like real racing, with turns), your DeVille does... What again? Has a paintjob and some hydros? That certainly qualifies you as an expert on performance, doesn't it? Especially with your "ceramic plate the intake and throttle body" ideas that are completely idiotic in concept. How exactly, could you explain, would coating the intake manifold with anything increase combustion temperature? Much less the throttle body...

Just remember, at the end of the day, you need hydraulic pumps to make your DeVille get three wheel motion. I can lift my front right tire off the ground because of the combination of power and sheer grip my car has.

[quins90lac]

thire are so many things you can do to make a car handle better and preform better . go look on car domain for the blue devil that would be Ghost C car . i even think illumina's car is on there to i wonder if he ever got that turbo put in? Also if you start off with say the asg 5.0 and then do some mods on it you could see probity around 320 hp if not more as far as handling you talking about a uni body car if you want it to handle better you got to do some work there to. and as far as you running hydro's on you car i hope you have it braced up really good or your going to start to crack that uni body right in half

Daily: 2001 Jaguar XJR, modified with cold air intake, arden springs, and flowmaster exhaust. Like I said, I had this deville stock for a while. I know how a deville handles. The weight difference in a stock deville vs fiero is about 800 lbs. Fiero: 2790 lb, Deville: 3519. Sorry, I was originally looking at 4 cylinder weight for the Fiero.

Ceramic throttle body won't help, but the bottom of the intake manifold will repell heat, allowing more head to stay in the block. like I said, been done for a while.

So you're saying your deville has a curb weight of less than 3100 lbs? There must be nothing left of that interior. Wouldn't imagine it would be that comfortable in driving.

That's what my deville does. Provides a lot of driving and riding enjoyment and comfort. Unlike some people who just throw on bolt on crap, I fabricated my own seats, modified the rear using an ultra thick memory foam. The whole suspension system, fabricated. there is nothing really bolt on for hydraulics that will work well with this car. The ride quality is decent. Not like stock, but still a hell of a lot better than my gf's 03 cavalier.
