well we should be racing this weekend coming up from a dig,i also just bought scorpio 1.6 rockers so that should help me a little

 

the cobra is S/C and the LT1 is N/A. from my personal experience cobras make about 400 rwhp i have a friend with a 430 rwhp with just a tune and borla catback. I have seen its very hard to get LT1s to that power with stock cubes and no boost. but that being said the cobras downfall is its IRS the solid axle on the LT1 will help alot with traction. so i would say if you are racing him from money race him from a dig and practice your launching.

 

A bone stock one wont make 400rwhp, it will probably make teh same if not more than his lt1 but thats why i said froma dig because he will have the advantage with getting out of the hole like you stated and thats why it would be a closer race than with a roll because thats where those cars get everyone at is top end. And since your running radials and he is on street tires you will def get the jump and its going to be him trying to play catch up in the 1/4

 

From a roll I don't think you will win. The 03/04's put about 360 to the wheels bone stock. I've seen more than a few put down right at 400 to the wheels after installing only a catback. And don't let the IRS fool you, it hooks up just fine. If you got DR's to his street tires, the only way I would run him is from a dig. And hope he doesn't hook.

BTW, make sure you check under his hood for a pulley swap before you race! Even though the belt guard is still on it doesn't mean that the car is stock. The mounting bolts for the belt guard as well as the pulley itself should have a yellow line painted across the bolt and nut. If its gone or misaligned I wouldn't take his word on it being stock. If that's the case then you could end up playing with a car that could potentially have up to low 500's to the wheel. Hope this helps.

 

Around here the 03-04 Cobra's stock are putting down mid 360's to low 380's rwhp STD and about the same rwtq.

They also run from low 13's to high 12's @109-113 given the driver, weather, traction....etc.

I see your combo and I see maybe 320-330 rwhp STD, enough IMO to get into the 12's@108-110 mph.

That being said, from a stop or roll, it should be a good race.

Dyno sheets do not win races....

I would though put a 150 shot nitrous on the car, just in case because if he pulls away pretty easy from you, he probably is not stock, then all bets are off and hammer him.

I would also try to race him at the track....then there is little excuse for bs'ing about the race.

 

o that must be what my buddies car had was a catback i thought it was stock when he made 400 but i can check with him. I know IRS isn't really bad but its not as good as a solid axle but not enought to make up for a severe amount of power difference between the 2 cars.

if i was the OP i would find a small shot or be ready to fork over $100. It won't be a blow out but i dont think you have as good of a chance as he does.

 

With that little cam you might as well just hand over the money. You will lose even if it is from a dig. Save the money and put it toward some more mods.

 

My cc503 LT1 was dead even with an 04 Cobra that had exhaust and a tune.

 

Just because it is a smaller cam does not mean it will not run well...I ran high 11's with a small cam...and that was years ago when I did not really know what I was doing.

 

I have pulled exhaust/intake 03/04's in mine with a stock bottom end and a CC306.

 

well he is not doing anything to his car for sure,i known him for a while and i know for sure that hes not the best driver thats why i agreed with the bet lol,if i loose hats cool i just wanna see where my car stands rite now

 

id buy a nitrous kit...

 

i agree with Canton, dyno sheets dont win races. Mustangs have inflated hp numbers as it is, everytime i see them at the track i rarely see anything over 13's in that year cobra's. There are plenty of guys on here running small cam's and puttin down low 12's to high 11's. So if you have your car setup right i think you have a chance. The rolling start puts you at a disadvantage, i'd try to go from a dead stop. If he bitches about you having drags, give him a length. Those 1.6rr's will def help.
