Am I really out of line asking 4200 $ for my z28? I keep getting offers of 2800-3000. Ill part it the **** out before I let it go for much less than 38-3500 $ at least

You have off road x pipe before headers? If so not a lot gained with adding headers really. Also wheel/tire eating up few ponies and makes hard to compare numbers. So you have an airraid cai or c&l? Also what kind of timing are you running?.
Is the GT taking out to 7800 also?

So anyway. I talked to my buddy today in the boss. His car made 443whp at that dyno with high flow cats (more power, more restriction). Turns out, he only made 430whp with the tune i have in my car (tuned by the place we dyno). The only reason he made 443, we because he added 3 degrees of timing. My car made 434 at 22 degrees... his made 430 at 22degrees. So much car is actually right where it should be...just has a conservative tune. My tuner refused to add any timing to it or attempt to lean it out. My afrs are between 12.2 and 12.4 all the way up. The GT and other boss both run 25 degrees of timing. So i know the power is there in the tune... but im not going to reach for it yet. There are other things im interested more in.
So heres the testing from the CAI. First... my car rolled 426/372 with the C&L. We then strapped a JLT air intake to it... made 429/376 (did back to back pulls with both intakes and made the same power. All pulls were done with 195* coolant temps). We then removed the maf reducer and reinstalled my C&L intake. Rolled 434/382. Made the best of both worlds... Now it didnt take rocket science to figure out why this was like this. By removing the insert, the maf housing was now the same as the JLTs. However, the JLT necks down at the TB to match the stock 79mm tb. My C&L matches perfectly with the 85mm TB. Not to mention the C&L is just night and day how much better it fits then the JLT. So we are going to port my TB tomorrow(not make it bigger, smooth it out for velocity) and the same to the maf housing. Going to try to get more power out of it by massaging things here and there before i attempt maximizing the tune.
Little less but its all in the tune. Ultimately, im happy with how its performing
Thanks guys
As far as comparing my car to a GT.... at one point... it made a full 35wtq more then the GT did. And between 3500-4500 rpm... i picked up 50wtq over my previous dyno of 417/369. Peak numbers arent everything. We all know this

haha true... My goals arent crazy high this time out. Just would like to improve and get some seat time. 11s and 120+ trap speed. Seems second gear is MUCH easier to hit now with the braided clutch line and new shifter. I have around 20 days to make sure everything is savvy. Im also picking up the SCT Livewire unit this week. Its absolutely badass. Ditch that stupid handheld Xcal tuner.
And be careful... if you put too much time into his car and not enough into yours, he might pass that ls6 with his ls1

I agree with this. Thats just what my tuner said. I found my missing 10hp anyway
I actually have some great CAI data you might find interesting. I had stock cats that were opened up to 3 inches on both sides matched with the bbk shorty headers and an after cat x pipe. This actually proved to gain me quite a bit of power. At this point. My buddies boss 302 made 401whp with tune, axle back, air intake. My car made 417whp with tune, cai, tb, catback, shorties.

Also why only 22*. I ran 26 on my GT and others are doing the same thing. You have some power left on the table there also. Just have to get a little aggressive with the tune. **** you already have forged internals. I ran my A/F right at 12.8 with that 26* timing. I know some guys are running 27-28 even. All on 93. SO with the little smoothing then some more timing I bet you gain some power threw out the power band and peak numbers.

He said it was a 2013 so he was very lucky! The guy driving the Camaro won't feel so lucky when the cops knock on his door though...

Well that example isn't 'all else equal'... The c5z has notable differences in weight, gearing, etc. I would also cast some doubt on a 290rwhp c5 trapping 109 unless the Dyno was stingy. ~310 is more like it... I made 324rwhp when I trapped 109.

If we were talking Corvettes then my numbers are spot on.
My 2000 C5 made 294rwhp on a "average" dynojet (same dyno your average 6spd F-body is between 300-305). Ran consistent low 13's @ 109 traps. Also weighed a tad over 3200lbs. How much does your F-body weigh?!!!
EDIT: Now that I think about it, the C5 "Hardtops" and C5 Z06 weigh nearly identical...3100lbs range. With Z51 gearing in the base C5 would minimize the gap as well.

this is true the C5Z is geared much better than a C5 or fbody. I've owned multiple 6 speed GM cars over the years, this one is by far geared the best from the factory with the GTO being 2nd.
