does anyone know the horse power/specs for a 1989 cutlass supreme international 2.8L V6 w/ a automatic. If so it would be very helpfull

Of course, wait 'til you see what it's actually putting to the ground. Ouch.

125 or 130hp depending on what book you look at

160ft lbs of torque

 

I own a 88 regal 2.8, I know.

don't be knocking the 2.8

 

Not knocking the 2.8, I'm knocking FWD driveline loss. The mighty 3.4 only puts 168 of its 210 crank horsepower to the pavement.

 

In fairness, my old 2.8 '89 GP spun the tires much easier than my '95 GTP. Not sure why...

ummm, FWD has nothing to do with it, FWD actually has LESS drivetrain loss compared to RWD, to turn a drive shaft the length of the car, or go right there a foot or 2 to the wheels. even if the 3.4 was RWD< im sure it would have the same, if not less horspower at the wheels

and it spins better because of the fact the 2.8 has torque at low RPMs while the 3.4 has all its torque at high rpms

Yea, my dads 2.8L does plenty of that on its own when it's cold out. :lol: :joke:

Really?

 

I swear to God my dyno sheet shows 178. And this was on a 200hp motor, not 210. And it made 186tq at the front wheels.

your engine put down 178whp. it also had a 5-speed. 168whp sounds typical for an auto LQ1. close enough.

The 2.8 would probably be lucky to put 100 hp to the ground. Drivetrain loss is a kick in the crotch for cars. :x

as long as the transmission was in good shape, i'd buy another 2.8/3.1 car in a minute

When I changed the plugs it lost so much power. i used to be able to squck them leaving a stop sign after we chaged them it wont do anything anymore im lost. i cant try to ware them in currently cause i broke the CV shaft so it dont move. I dont know what to do. :bawl:

That's a pickle. I can tell you now, unless you have a faulty plug, the plugs aren't you problem. Does it run bad?

We're definately talking about automatics here. We know that the 5 speed has about 5% less loss than the auto...thats where your extra 10hp came into play.

 

My Turbo 3.1 put down 182.2whp and 272wtq when it was completely stock. I'm putting it on the dyno in the spring to see what 5psi more boost, ported heads, a cam, ported exhaust manifolds, and an UD pulley did. I'm hoping for 240 to the tires, but who knows what it'll actually be.

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.

:thumbsup: That is awesome as heck. I can't believe GM rated at engine at 225 crank torque, when it put down 270+ at the wheels. That's well over 300 lb-ft at the crank! :cheers:

Just take a look at what the 5 speed guys are putting down with very mild mods. With just a chip they're putting down like 320+wtq.

first, i'm sorry your parents raised you wrong being a ford boy and all :lol:

 

Pull the bosch plugs out (just a guess) and buy 6 delco plugs, your spunk should return. The CVs in these cars are pretty easy to replace. pull the 36mm bolt and washer, pop the balljoint out and slide a tire iron behind the axle where it slides into the tranny, pull a few times it will pop out. put the new one in by doing everything in reverse, ta da,
