What numbers should i see with the stage 2 upgrade? @ whp? and 1/4 times

??? any one!

 

I would sya just stage 2 is around 230whp and between 13.9-14.2 @99-103mph

 

with driver mod 9.2 you could be in the high 13s but i think most people are in the mid/low 14s

 

haha

 

~240 with stage II and your GMPP exhaust

as far as times go, its about driver mod, elevation, and track conditions. high 13's possible.

 

With 450 elevation, a 2.9 nates pulley, and no cooling mods and I ran a 14.06 at 104.2mph with knock hitting upper 7's on 93 octane gas on stock tires, so thats a hint of what you can do.
Going back to the track next week and running 100 octane to see if I can get into the 13.8 area!

 

13.70 @ 103

stage 2 with k&n

 

and driver mod 18.66

 

and trunk monkey stage 4

 

and smiley face stage 8

 

And Fat friend removal 2.1
j/k John...

 

ROFL

 

I almost sprayed Pepsi Max everywhere.

"You car is slow...."
"It would be faster without you in it."

 

can i run the stage 3 pulley the 2.9 with the stage 2 re-flash, or do i need another tune for that??

 

you can. nothing that big of a deal

 

u meanstg3 pulley 2.99, negligible 1/2 lb of boost. BTW can ayone tell me how i got 25 whp with an axtra1/2 lb of boost myself and an A/F of 10.98 at 6700 RPM's with just a good tuner w/o tuning software and i can't even find out how he did it.

according were u from but prolly for u about 14.0-14.5 with a 2.0 60ft at sea level around 50degrees and low humidity is a bout 13.6-13-7 perfect shifts per say

 

id say 230whp and run about 14.1-14.5...

 

Up here in CO there's about a 15% power loss from sea level, so I'll state mine in terms of the 18% gain that GM reports. S2 should bring you up to about 205 WHP (uncorrected) stock we're at about 175 WHP up here (again, uncorrected). I say that because it will give you a realistic expectation of what you can run up here. Don't expect any better times up here with S2 than you'd run with stock at sea level under the same conditions. Plenty of 13 second cars dip into the 14's up here though, so I wouldn't sweat it too much, altitude is an equal-opportunity power robber.

We have some wierd temperature swings up here too (2006 saw a year low of -13F and a high of 106F in the Northern CO area, a 119-degree swing), so our DA is all over the map. In the winter our DA can be around 3k feet some days, so faster times are possible, but on a 100 degree day in the middle of summer with rain expected that afternoon, DA can shoot up to 9,000+ feet quickly. You won't be going anywhere fast that day.

Hope that helps

It's not all about the peak boost, Stage 2 gives you an extra 3lbs of boost and a decent peak power gain, but the real gain you should be looking at comes in the middle of the curve, where stock is weaker. Smaller pullies have less rotational inertia, so spinning them is easier, boost comes on more quickly. There are plenty of reasons to go after that extra 1/2 pound of peak boost, especially if it means a better area under the HP curve from 4k on up. If you wanna geek out on it, get your hands on a couple data files for stock and Stage 2 dyno runs, slap the numbers into a math program, and do a partial integral on the stock curve vs. Stage 2, starting at 4k and going to 6500. You'll see what I mean.

 

do some research before you post.... theres a million threads out there that have this information...

 

Probably an honest mistake by the OP, he does live at high altitude. Not much info for us CO-UT-AZ-NM folks because there aren't too many of us around compared to the sea-level people. I looked for a few days before finding what I needed, and some of it wasn't on this forum.
