This is POST #10
OEM HP Ratings




THE FBODY IS UNDERATED, YES, YOU READ RIGHT. THOSE ADVERTISED NUMBERS THAT GM QUOTES ARE BULLSHIT. WHY GM UNDERTATED THE LS1 IN THE FBODY WE'LL NEVER KNOW FOR SURE BUT THE FACT IS THEY DID. AN LS1 IN THE FBODY WILL DYNO ANYWHERE FROM 270RWHP TO 320RWHP DEPENDING ON YEAR, TRANNY, AND OPTIONS (SS/'HAWK OR SLP OPTIONS).

I REPEAT AGAIN THE 98-02 CARS ARE UNDERATED!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!



PLEASE READ THE STICKIES

 

Way to go, Mikeeeey....

 

O ya here are the Real Specs, and YES EVERY CAR IS DIFFERENT SOME WILL HAVE MORE SOME WILL HAVE LESS, BUT THIS IS THE SPECS FROM THE FACTORY.

Horsepower (hp / kw @ rpm):


310 / 231 @ 5200
w/ WS6 Ram Air: 325 / 242 @ 5200


Torque (lb-ft / Nm @ rpm):


340 / 461 @ 4000
w/ WS6 Ram Air: 350 / 475 @ 4000

NOW LETS HEAR THE EXCUSES

 

Yeah and the average birth weight of babies is what 7 lbs about. I bet all of us on this forum where born at 7 lbs on the dot right lol. Don't believe everything you read. Throwing up SAE engine #'s is pointless and can't use that for arguements sake?

 

Why would you post this stuff up twice?

 

I was trying to agree with you on how they're at the same power levels but argue how you think the suspension is useless. And better suspension of SSs, ws6s, firehawks, or what ever don't handle better due to only bigger wheels and lower profile tires.

Sounds to me like Settlemire has a hater which is a good thing I have haters too

So what did Settlemire do, that was so bad, to you? You don't dislike him too much seeing that you drive an fbody.

 

Because its a m6 horse power was better on those T/A IS NOT FASTER THAN A T/A WS6 .

 

If you did a little more research then you may come to the conclusion that the Suspensions only real difference is the front swaybar size. The springs and shocks aren't enough to make a substantial difference.
And as for Settlemire all I can say is He has No Business calling himself the F-body Father considering he wasn't working for GM in 1966-67 when the cars were being introduced. And he's always been more of a marketing guy for the Camaro then for the Firebird. Not that GM did much F-body Marketing after 1999.

If you figure about a 15% loss (for M6) then if I'm at 300 RWHP then the engine is making around 345 HP at the flywheel. So it's obvious the GM ratings are Bogus, But our friend frostbitten 09 hasn't figured that out yet.
And I agree All F-bodies are the same. But only until the mods start going on.

 

On my car, afaik, the front sway is all that was different on my SS, but I do think there is more to it seeing how my car has the FE4 code which is some jazz about high performance handling. I think the springs may be different but the shocks are the same unless they were upgraded to bilstiens.

Fact of the matter is the SS, ws6, firehawk, and so on do handle better than the other cars and its not just due to tires and wheels,,,... no matter who settlemire was working for back in '66 and '67.

 

Settlemire was probably still in Highschool or College back then.

1996 thru early 2000 WS6 and SS's came with the 1LE springs 360# Front 130-180# Rear where as stock LS car springs were 292/114. In late 2000 GM cheaped out and removed the springs from the package. So in essence the later cars just had the 32mm F swaybar and the bigger wheels and rubber.

I've never seen dramatic enough skidpad differences between the two setups that would make me think that one was much better then the other.

The Billstien option was a different setup with Eibach Progressive rate springs and the aforementioned shocks. This was touted as a much better riding system with great road manners.

I personally have Strano Springs, Swaybars and Koni's which is a vast improvement over any of the factory stuff.

 

nuff said I've got the strano setup on the sway bars and all I need to complete my full suspension is an adjustable panhard, springs, and shocks.

Strano knows his stuff.

AFA suspension goes on the stock ones I won't say there were big differences, but there is still a difference. HPwise, there was really not that big of a difference. It was so small that I would say it is negligable(sp?)

This is a fact though, an ls1 is an ls1. From 98-00 they used one cam and 01-02 they used a different one and put on an ls6 intake and supposedly better exhaust manifolds. No matter what F-body you had, in stock trim they all got this respectively depending on the years. No matter what

no matter who you are, lid and cat back don't do enough to brag about, unless it sounds good

 

Agreed

IMO, At the end of the day if it puts a smile on your face then that's all that matters.

 

that's why I have to keep modding I keep out growing my performance

 

I raced a stock ws6 with my stock regular T/A and beat the crap out of him by 2 cars....its all about the driver

 

When you're right you're right lol. year to year differences are way bigger than T/A to ws6 differences. the ws6 has a "different suspension package" not sure what it consists of and really don't care haha. either way I think someone could take a base T/A and payless, and just mod it to make it faster even if the ws6 was faster to begin with. ws6 is mainly just a name, and costs more. i got mine because i like the hood better.

 

Its only fast until you get used to it.

A buddy of mine just spend 20k on a 1998 convertible vette. I printed out that Hot Rod article to show him. He will be pissed lol.

 

Most of us F-body people use that page to show how equal the cars really are. In reality the vette should be quicker because of it's better power to weight ratio. But all in all it's a drivers race because the fastest or more powerfull car is not always the winner.

 

i always thought the air box was taller on a WS6 car, letting in more air.....etc

 

All the other boxs would have to be pretty damn small for that to make a difference too. like the rest would have to be open 1/4 of a millimeter and the ws6 still have its like 4in, then yea it would make a difference but I don't think it helps, typically. Now at top speed I bet it helps with the hood design and all.
