I have a 95 z28 6speed, It hit 150K miles on the way to dyno it saturday

I did 290/322 on what seems to be a completely stock car I don't know of anything done too it.

car can be seen here

Did you buy it used? Cause the paint job ain't stock. Heads could have been ported, but even then, thats a lotta dyno for that many miles.

 

There's definetely something done... Those numbers are too high for even a real freaky freak.

Very nice paint job by the way.

 

yea I had it painted

these are my fav pics of it

so what you guys thinks done too it? I need some headers that will put me over 300 rwhp on an lt1

I am already beating some ls1's hp wise and in races

 

That cat-back isnt stock

 

I dunno know very odd numbers... Very cool paint job!

 

glad you like the paint alot of peeps call it gay or whatever but I like it and thats all that matters and it turns so so so many heads, I can see people pointing @ it etc.. all the time and they dont' see me cause my tit is real dark heh.

anyhow opinions wanted

p.s. one of turbospeed's turbo kits will most likely be going on this car as soon as he gets it done and I get the $ i'm very very impressed by it and saw it in action saturday

 

As already mentioned, the catback isn't stock. Looks like a Borla? to me...

Also the cold air intake isn't stock. It's a G2 which is pretty much the worst cold air out there, but still, not stock.

 

you are right there.

its borla cat back exhaust system but! I cut out the cat and it was super super raspy so i bought a dynomax bullet muffler and welded it up where the cat was 3in/3out muffler and its now on the super raspy mode but oh well lol it runs pretty decent for what it is so i dont bitch

/edit and yes it has that g2 crap I'm going to make a homeade cold air kit for it out of plastic pvc pipe

 

Also your ET is a good indicator that it isnt stock:

Best E/T: 13.686 @ 103.90

You are almost trapping 104...i would say something has been done that you are not aware of.

 

yea i have hit 105mph before but I had crazy wheel spin off the line it was like 13.8@105 I gotta get some nitto 555r's

also my lt1 is one of those w/ the intake leak that lets oil into the get on the clutch so i've replaced like 3 clutches but this next time i'm going to have it all regasketed and fixed so no more leaking

found one of my old timeslips
r/t - 1.075 << ugh
60 - 2.455 << more ugh
330 - 6.160
1/8 - 9.156@82.23
1000 - 11.722
1/4 - 13.891@ 104.04

thats only other one i can find laying around other than my 13.6 one, my clutch gets so crappy after even setting in stage lanes because of the oil slippage from intake or rear main not sure where all its coming from but eiter way soon and very soon it'll be all fixed

 

I'd try to see if you have the stock program somehow. Check for a TB bypass and free mods.

With free mods and programing i got 277 rwhp, you have a catback and off road pipe on top of that and i could easily see that making the 13 hp.

I don't think it's that freaky, just a car in good tune/well maintained and probably with a modified program.

 

Dude, I have a friend with a car like that. His is a '96 Z with a intake and a catback he made 305rwhp. I was convinced the previous owner put roller rockers on it until I saw the engine bay! It was freeking discusting. It looked like it had never been touched. With a cutout and stock cats on his car he beat me on the hiway after my LT intall!

 

That color change must of cost you the price of the car, cause not only is a color change expensive, but so is that color paint...I am looking to do a color change, but don't have the money....how much did you pay for labor?

 

I would venture to say you have a G2 car. Given your location, and the fact you have a G2 CAI, a G2 TB Plate, and a Borla catback, which is a G2 Favorite. www.lgmotorsports.com The # is on there, call them with your VIN I think they can confirm or deny it, and tell you what mods it has.
