What will my 4th Gen run? New to the LS game and recently picked up a 02 Z28 with an auto trans.
Previous owner apparently went a 12.2 according to this site in 2008 but I've switched a couple things since owning it.
Mods include:
Ported 243 heads
Fast 90 Intake
Comp cams 273HR (224int 230exh at 581/592 114LS)
Ported stock TB
K&N cold air intake
Stock mass air meter
Electric water pump
Kooks long tubes, Hi-flow cats, Borla adj cat back
Upgraded injectors and fuel pump
Built auto trany with cooler and 3200 stall
Moser 12 bolt with 3.73 gears
Stock shocks and springs
Upgraded suspension (BMR control arms, subframes)
The car made 380RWHP
I plan on using a 26' Mickey ET street at the track for test & tune.
The car has a Nitrous kit on it and once I get it dialed in NA I will
hit it with a 100 shot.
My goal is high 11's on motor.
Any guesses? NA and on spray?
Thanks

h.p seems a bit low and wouldn't hurt to have a stall a little bigger for n/a times but i think mid 11's should be attainable. it will like the sauce with that cam/stall combo,so high 10's @ 125 or so should be fairly easy.

I was told by the tuner that my set up usually makes 410rwhp on his dyno in a 6spd with a 10 bolt rear end but my auto and Moser bring it down.
I think the previous dyno numbers were in the 350-360 range with the smaller cam and 10 factory bolt.
I stressed how reliability and dependability were important for this car so he didn't go aggressive with the new cam and tune.
I recently picked up new upgraded trunnion rockers but don't expect any increase in power with these.
I would have installed an underdrive crank pulley for a few HP but I just installed all new belts on the car so I don't want to swap it now.

I would be real impressed if it ran mid 11's NA.
Anything in the 11's and I'll be
Really looking forward to some test and tune with it.
These cars seem to 60ft very well with a good tire.
