All cars were not created equal. Besides he did say stock. Alot of stock vettes trap 106-108, atleast at the track that i go to.

Also you need to consider that c5's were made from 97-04. A 97 would get landed on by a 04. I dont know what is all different on the besides the intake, but i'm sure theres a little more.

 

when I just had headers and exhaust, it was around the year 2001. So there were no LS6 intake C5s running around. And I would disagree that they were "slow C5s" because they are all slow stock. SHORTY headers none the less, and full exhaust I dynoed 296rwhp 327rwtq... I dont see how a 300rwhp 300rwtq C5 could win that race...

 

Pretty easy actually, its called less weight and better aerodynamics. And a 300rwhp C5 would be a pretty weak one.

 

...it's called a pretty stock one. I had a '99 and it dyno'd right around 305-309rwhp bone stock. Still ran 107 mph.

 

Bone stock and assuming that both are running properly, an '04 wouldn't beat a '97 by much. Maybe a carlength in the quarter mile.

300rwhp is a little low for a C5. 310 is probably average. 300rwtq is a lot low. Try 330-340.

 

340hp vs. 350hp (advertised)

pretty accurate.

 

With the mods I have I have no problems with the c5. And I stayed really close to a 2006 zo6 with a old man driving it. Your car has some issues, it should be faster than my car.

 

my heads were ported by a local guy. he said he was able to get to within 90% of 300cfm i dont have the flow numbers on hand i need to look for them. and the guy who tuned my car selected the cam from the numbers my porter gave him. the car wasn't dyno tuned but it was tuned on i guess you could say real world driving, as in he had a lap top hooked up to the car and would take it out for a ride and tune based on his readings i guess. if the cam is too big thats fine because i am planning on stroking the car in the future. i am just kind of trippin out because i would think i would AT LEAST be able to be right there with him with all that is done to my car. oh and we went from bout a 35 roll.

 

Do you have gears in your rear end? If not, thats hurting you
new TB? 48mm would KILL that cars top end

 

Advertised, yes. Actual, a little less.

 

Well theres something way off on your car if you are loosing to a stock-stockish C5. And flow #'s aren't worth the paper they are printed on.

 

i'm running the stock 3:23 and still the stock throttle body. Speed_Demon24 do you have any idea how i could narrow it down and possibly pinpoint the problem? Thanks everyone for your input.

 

I'de put it on a dyno to check the a/f and see how the hp/tq curves look.

 

i dont know what your problem is. i have stock heads stock rear end stock suspension and a cc503 cam and i go 12.8 all day long off the bottle.

 

alright thanks fellas. nah couldn throw my car in the lake cuz looks too good sounds too good and just gotta figure out the gremlin thats keepin it from running good!
