Hello, i have an 03 cobra that i have had for about 6 months, and i got a dyno sheet stating the car put down 481/440, and the guy i bought it from said it has been but i dont know weither to believe that or not, beacuse he said the car had 4.10 gears in it, and it didnt. The mod list is 2.93 upper only pulley, cai, heat exchanger, catless x pipe, and exhaust. Do the mods match the number? Beacuse i honestly dont know if i believe it.
How to tell if my blower has been ported?

I honestly dont know, the dyno sheet i have doesnt show boost, it says 12.8 MAX A/F. At WOT it barries the boost gauge, and clearly goes past 10.
12.8 a/f ratio?!?! .. surely you're joking!
That's way too high .. but if you knew what kind of boost it is making with that pulley then it would give a better idea if it is ported or not .. but before finding that answer out .. you may want to consider getting it tuned .. that a/f is unsafe
11.5-11.8 is what most ppl are set at

I can try and post it here in a little bit, but im not joking it says that, but it doesnt give any boost number's at all.
Dyno numbers sounds like its ported to me! Very similar to what mine made with that upper pulley!
Thats great numbers if its not ported...
it may be unported . mine is unported and i am making 500/518 with some of the same mods . put some headers , pulley kit and throttle body and a good tune will help too
You'd be the first one since the cars came out that made those numbers just to let you know. Nobody has ever broken 500hp on an unported Eaton.
Unless
It was on E-85 and I'm pretty sure someone did it a while back.:beer:
wow really ? with the mods done to car it was dynoed tuned too by hbh
Your gonna have a lot guys in here questioning those unported numbers. Was this done with pump gas? Who did the tune? Can you post a dyno sheet?
mods done to the car is full exhaust header included idler pulley set throttle body and inlet heat exchanger, cai i 2.8 pulley on the blower and sct tune which like i said was done by hbh . i am not sure if it helps it pulls like a son of a gun too
yes on pump gas . horsepower by herman did the tune. i will see if i can dig it out . the datalog pull was 460/445 running super rich once the a/f was right with the tune put down 500/518 i coudnt believe it either when he told me .
That's really impressive.
Ok so which is it? Cams or nos? 
neither no cams or nos. i gues just right mods and a really good tune
