this is pretty accurate.

Yes it is. Since all LS1s make roughly equal power, it makes sense that the fastest is the lightest.

 

Not exactly. There is only about a 40 pound difference between a stripper Z and the other various models. Not including Verts.

As for horsepower differences. Like was mentioned some cars run better than others. Tolerances, miles, etc.

The minor differences on the SS, WS6, and Firehawk kind of get washed out due to this but they still have free-er flowing exhausts, bigger air box, etc so it's really hard to say. Hell factor in the weight of the driver also. The cars are so close it's really comes down to how the vehicle runs and has been taken care of.

 

i agree.. and i got an ss. unless equiped with the slp options (i got the exhaust) then the SS/ws6 is no better.. excluding looks

 

Do you have a source for this?

I have to believe that a loaded F-body has more than 40 pounds in extra weight. The difference in weight between cloth and leather/power seats alone is probably close to that.

 

get the Z and mod that **** to hell

 

so how come when my car was bone stock, i raced a bone stock 00 Z28 and beat him????? if you say they're identical then we should've stayed neck and neck the whole time, right? or am i misunderstanding you? it was 1/4 mile length and A4 vs A4 if i'm not mistaken the SS camaro's got a better gear ratio than the Z28's from the factory and wouldn't a better flowing exhuast and intake get some more hp?????? if that was true i wouldn't have gained any hp when i put on my lid, filter smooth bellows, y-pipe and loudmouth exhuast

 

different drivers. you can race either one for the win. there IS a tad more hp in the SS/WS6 due to the ram air and better designed exhaust, but it's nothing the Z28's lighter weight can't account for. even without the extra weight, it's a driver's race.

 

It's somewhere in the stickies and has been posted many times. The weight difference is minimal on our cars. Stock that is. You start adding stereos and cages, etc. or stripping out stuff then that all changes.

 

Looks like I was a little off by the numbers but it looks like the weight varies from about 40 to 80 pounds between a Z-28 and WS6 and such.

so in theory if i race a guy who weighs 30 more pounds than me and has the same exact car as me and the same exact mods, i should be able to beat him in a race?

 

If all other factors (weight of car, driver skill, reaction, mods the same, cars run the same, etc.) are equal then maybe. He may get better traction though with the extra weight. lol

 

What tires did you have? What PSI were they at? How hot were they? What about him? How much gas was in your tank? His? How much do you weight? Him? How much extra weight did each of you have? Surefly you have something in your car besides floor mats and yourself. What condition were your spark plugs? His? How many miles did each of you have? What Air/fuel ratio were each of you running? Did you hit the gas to start your race at exactly the same instant? Did either of you have a window partially down, and if so were they up/down exactly the same? Was there a side wind that one of you would block from the other? What gear ratio did he have? Maybe he was unlucky and got the 2.73s.

Surely you get the idea. Too many variables, which is why you can't run two Z28s from the same year with the same tranny and expect them to be a perfect tie.


You are mistaken. A4 gear options are 2.73 and 3.23. Plenty of Z28s have 3.23s stock...mine included. It's option code GU5, IIRC. On the window sticker is "performance axle ratio" or something similer and cost $400.
I do believe that all SS models came with 3.23 gears, not sure though, that is probably what you are thinking of.




SS's didn't come with a higher flowing intake. As said previously the only way to get additonal power from an SS/WS6 is with SLP Y2Y options, which are basically like adding an overpriced (IMO) catback and lid to you car.

 

thats what i was referring to the SS came stock with the 3.23 gears and had the option of 3.73 gears

so if you ordered that option it did COME with the catback and lid, hence the 345 hp SLP package in 01-02. blackwing lid (ONLY AFTERMARKET LID SMOG LEGAL FOR F-BODIES IN CALIFORNIA) without those stupid resonators on the side. which actually does make a differnece, i know this cause i had the stock intake on my SS until last november, and a better catback isn't the SLP option catback less restrictive?? similar to purchasing the GMMG catback exhaust. yeah it's another catback but why would people swear that you gain HP with it?

this is the stock lid

and this is the SLP option 345 HP package lid

notice the blackwing symbol on the bottom right side of the lid

would my SS be a stripper? cloth seats, no traction control, no disc changer in the back, only power accessories are windows, door locks and mirrors and it's a hard top

 

you know you would pick the paper bill so u dont have loose change or the weight in your pocket

 

mmm at no point where 3.73's ever an option. it was 3.23 for an SS auto, 3.42 for every M6 f-body. for A4 Z28's it was 2.73 standard with 3.23 as an optional performance enhancement.

FWIW my formula came with the SLP lid and it looks nothing like that...



mine looks like the aftermarket one minus the sticker.

 

No. 3.73 gears were not an option on ANY factory vehicle. Like I said earlier, autos were 2.73 oe 3.23. Manuals were 3.42. That is it.



Most SSs and WS6s did not come with those overpriced SLP components. Like I/we have said all along, the SS or WS6 will make more power if it comes with those SLP options. However, you can buy a Formula or Z28 for a lot less and simply add the cat-back/lid of your choosing to make as much or more power for a lot less money.

I don't worry about what is smog legal in Kommifornia, I will die a happy man if I never step foot in that state again, and God as my witness I will never, ever, ever live there.
