On another note that seems to be lost...FWD DOES have less restiction then RWD. Less moving parts, not as many peices, less wieght.

[gp90se]

ill still take RWD, more power potential

 

Off topic: anyone run a 2.8 w-body against a 2.8 f-body?

[z34_nut]

yeah...Really wishing my car was RWD...oooo how much fun that would be...

the 2.8f-bodys weigh more and have 5-10 LESS hp.

[Prospeeder]

2.8 Fbodies are Carbed i do belive, and weigh like 200 lbs more

*drops head* dont talk unless you do a little reseach

 

there is only about 100lbs difference between a late 80s v6 f-bodys and a dubya and i think the 3.73 gearing in the f-bodys would give it teh w1n in a 1/4 mile race

[Prospeeder]

oh shut up, christ, V8 ones are a bout 200 pounds more, thats what i thought, and are they carbed or not?

 

according to this....a Fbody 2.8 would never beat a w 2.8

"Production:

Engines: 2.5 liter I4 90 bhp. 2.8 liter V6 105 bhp. 5.0 liter V8 145 bhp. 5.0 liter ("Cross-Fire Injection) V8 165 bhp"

[gp90se]

no, they went efi in 86 or so

 

92 base coupe f-body: 3105

92 4 door grand prix: 3155

 

so the cars weigh the same

 

2 minutes of research will go a long way

[Prospeeder]

i actually couldnt find it, typing in Fbody Weight, V6 Fbody weight, or anything of that such

[FordBoy]

my parnets didnt make me a FordBoy my parents arnt car people like i am so just because u dont like fords dont mean i dont have to and the plugs are champian i was told the fuel enjectors are know to go out on the 2.8. i started it up it seem that the miss has now gone away somehow i cant drive it currently so i dont know if it got its balls back yeti can tell more when i fix my CV shaft and a wishbone motor mount

that kinda-came from left field... Once you fix the cv shaft you should do a full tuneup. You already stated that after changing the plugs to champions you have lost power.... Are you sure you didn't cross spark plug wires? How about damaging a spark plug wire during the service? Also, I'd put in basic AC Delcos. thats what the car is supposed to have, not champions. (at least you didn't go with bosch) How about fuel filter, air filter, Oxygen sensor, and fuel injector cleaner? those are regular items needing done.

Yes 2.8 and the 3.1 can have bad injectors. I've only seen two injectors fail on 9 cars I've owned with these engines. Thats two in some 150,000 miles of me personally driving these cars, all higher mileage during my ownership (more likely to fail) for 1.4 million combined miles of operation. 5 of these cars are still rolling, 2 totaled, 2 junked for non-mechanical issues. At least they goof up on the tranny design like front wheel drive chsler and ford products (no offense)

Thanx for all of your help

My Turbo 3.1 put down 182.2whp and 272wtq when it was completely stock.

Seriously? All the specs I've seen on the T3.1 show it rated at 225 crank lb-ft torque. I had no idea a stock motor put down 50 lb-ft more to the wheels! Pretty awesome.

 

Mine is a freak too. That was running only 6psi when stock boost should be 7.5psi, and mines also the only LG5 powered w-body to go 14's stock. And my trans guy didn't believe that the completely stripped off gears in the trans weren't caused by neutral drops.

Was your 272wtq done with a modded boost controller though? If not, that dyno sounds skewed if it was on the bone stock boost control.

[BIGBULS]

He was probably looking at the begining of the torque curve, where the torque convertor was still skewing torque readings (they DO multiply torque after all ). Hence the 272lb/ft reading.

 

BUT.

 

From the stock manual trannied (swapped cars) dyno charts I've seen (which don't have a skewed curve), 3.1L Turbo engine's ARE underrated on torque. Truth be told, I expect they make right about 205hp and 275lb/ft at the crank.........some maybe a little more, others a touch less, but those numbers are very close.

 

Why else do you think they are able to outlanuch an LQ1 so hard AND still hold it on the top end?

[BIGBULS]

And BTW..............I have NEVER seen or heard of ANY W-Body's curb weight being south of 3200lbs.

 

Hell, stick a 2.8L '88 model with a 3 speed auto on a scale and I'll bet it's damn close to 3300lbs. And by the end of the 1st gens, even a base 3100 powered car is going to be nudging 3400.

 

 

 

Take for instance my old 91 LQ1 5 speed GP.............3420lbs on the nose with a full tank of gas. And that's a MANUAL trannied car........autos are abouty 50lbs heavier.

[pwmin]

hmm, mine weighed 3250 with 1/4 tank and the back seats out and spare tire out.

 

that was weighed at a local track.

[nebojsa_o]

My 96 CS with a 3100 auto weighs 3300lbs when I'm out of the car, and about half full of gas, maybe a little under.
