Well finally got the camaro back from the shop, had it dynoed....
heres my motor work:
Comp Cam 224/230 112 lsa, ported and polished heads, 1.6rr, CAI, hooker headers, 30 lbs injectors, walbro 225 pump, borla catback
today on the dyno i put down today
277 HP
285 ft lbs of torque at the wheels
so about 355 HP and 365 ft lbs at the crank

took it to the track for some test and tune runs and ran a 13.3 @ 105.51 MPH
60' was a 2.0
granted I havent been to the track since April and havent run this setup so I'm sure theres some time to be shaven off that quater mile but do these numbers seem right?

 

You are definitely missing some power, probably at least 60 rwhp.

 

I would agree too...but your track times aren't as bad as you hp, still not good though.

 

Yeah that didn't make any sense. His times aren't bad for 280 rwhp.

 

They didn't forget to tune the PCM, did they?

And however unlikely, which kind of dyno?

 

Ya if it is still running on its stock tune, it wont make any power at all lol especially with 30 lb injectors.

 

Something is really wrong with those numbers.

If you're still running on a stock tune, then you need to get rid of that because it's holding you back. Going from the stock tune to a mail order tune on my bolt on/HOTcam/ported heads car, I dropped about .5 second and picked up 4 mph in the 1/8th. If it knocks off .5 second on your 1/4 time I'd still say something is wrong because that would only put you at a 12.8.

 

I would be really bummed with those numbers,even if its a Mustang dyno.

 

Who actually did the work on the car? Something is seriously wrong. A little more detail on all the parts used would be nice.

 

Madz28 did the tune. The air fuel ratio, after a new set of O2 sensors is perfect. The people who originally did the motor work messed it up twice. Could something have gotten damaged from low oil condition to cause this bad or a power loss without something noticably being wrong with the car?
Also, I threw a set of ported and polished heads off from someone else's project on without flow testing them, could the heads be messed up and cause this?

 

I would think with your setup and everything working right you should
be at a minimun of 340 rwhp, and probably more like 360.

 

So is it most likely the heads are the cause of this? They're the only questionable thing in my setup.

 

Yes,They are suspect.I would do a compression check.Just to see if its ok.Does it run ok?

 

Maybe the cam was installed incorrectly or the timing chain is off a tooth. For comparison I made 340 rwhp with stock heads and shorty headers... at the track I ran a 13.058 at 108.5 with a crappy 2.116 60'.

 

Timing chain was installed incorrectly the first time. It has since been reinstalled... The car runs fine now execpt it does burn some oil when you're running it hard. I suspected maybe a valveseal or something had to do with that.
