More horsepower!!
Don't look at the pulley size as the main difference in the power....
Most of the guys in the 270whp range are running meth or an aggressive tune.
There are people with a 2.8 pulley, full bolt on's, and tune only in the 250whp range as well.
Just keep that in mind....
A 250whp SS/SC is still a quick car. If you are really interested in shooting for 270whp as your goal, look into a 2.7 pulley, 60# injectors, full exhaust, cooling, tune, and some sort of octane. 93 octane is good, but will only get you so far.

And what are you pushing out of those mods? Option b is definitely something I'm going to get, I've heard nothing but good things about it so ill get that with the zzp h/e.

Ok I understand all that, just seeing everyone else's figures does get you excited about doing the same or more but like you said, you don't know how aggressive the tune is. But I'll keep that in mind. For instance my buddy had a lightning and went from a 4lb pulley to a 6lb pulley and had the exact same power, so I believe the tune would have to factor in at that point.
Boost is also not the best way to explain power on a blower car, because it is a measure of restriction.
A 16psi SS/SC can make more power than an 18psi SS/SC. Airflow is key.
Option B is fantastic. I have been running it for years on my car.
Correct, but saying a pulley will give you x amount of boost is not accurate on a blower car. Lots of factors affect boost levels such as temp, elevation, climate, and modifications such as a free flowing exhaust.

And about the option b, never heard anything bad about it and you proved that point right there lol
With my mods and 3.0 pulley. I'm pushing about 240ish on a conservative tune til I can get to a dyno. I wouldn't run lower than a 2.8 in florida unless ur going to have cooling mods out the ass. IMO 2.9 is the safest if u only plan on using heat exchanger and option b

Yea with the gm stage 2 on my car now, my boost gauge goes to 14 maybe 15 because I'm too busy paying attention to the road lol, but a few more lbs wouldn't hurt and I also have this guy with a 99 mustang gt that swears up and down that he can walk me by 5 cars, but I'm pretty positive that ill beat him, I don't look down on my car at all I love it too much lol

Ok so I was talking to one of my good friends tonight about the mods ill be doing and he was telling me about the clutch in the car and if it'll hold that much power for a long time or will I have to purchase a new clutch with it or will I have to replace it soon down the road? I didn't have the answer for him so I was wondering what my engine will hold and how much the clutch will hold as well..

Ok cool thanks, and with the gmpp clutch or even a zzp clutch how long will that clutch last before getting a new one. My friend said that the ones they make for his car will go out like after 20k and it'll never have the same reliability along life as the stock clutch

My clutch has about 40k miles on it, the guy that owned my car before me had blew out the clutch at 56k miles so i replaced it with another stock one at the time since i didnt know about the gmpp clutch, im around 98k now and my clutch holds my power no problem and has many 1st, 2nd, and 3rd gear pulls down my highway logging and racing. It ur clutch is in good shape it should hold for a while just depends

Stock clutch is fine.... I'm at 285whp +, and have no slip.
Although, I will upgrade to a GMPP clutch when mine starts to fail.

Awesome cause that was going to be a big concern with me if I did all this and bam those goes my clutch and I have to drop $1000 into the car to get it back up again. I'm at 53k on my car now and I feel no slip or anything so I think the car will handle the power fine. And it's not like I get on it everyday or racing people everyday. I honestly only raced a few cars like a new
V6 camaro and a Daytona charger and I've beat them but other than that I haven't really raced anyone and for some reason I can't figure out why lol. So if my clutch does go the gmpp one will last me a very long time with the way I drive and how many miles I have on the car now?

And it still lasts a long time with all the beating it takes? And what kinda clutch from Ottp do you have cause I just looked and there's a crap ton to choose from lol
Alright awesome good to hear it cause they had a lot of options lol. And now brakes. I heard that a lot of people put the r1 concepts drilled and slotted rotors. But on some threads some say that you only need the slotted, why is that and whats the difference?
Don't quote me on this b/c brakes are not my strongest point, but I think the reason you do not need both is because it would seem to me that the brakes would not heat up good enough to because efficent on the streets. Only difference I think is that they cool a lot faster thus being better for track and autoX use
