03 Cobra VS rx7 results
Well i lost by 1 car at 120mph
1st gear i was infront gaining 2nd still ahead and pulling SLOWLY. 3rd gear he took me even and 4th he was by me. Damn them 6 speeds!vhis mods intake and catback. when he was stock he made 383RWHP
my mods are
DP MP CB Intake hardintake pipes light weight pullies racingbeat spark plug wires PFC and untuned and runnning rich so i dont blow up
i know i need to get tuned but, what else am i going to need.
i think an IC and the rest of my light wieght pullies, a Efini y pipe and i should have him???
well what do you guys think?

When I had all those mods I was hitting too high of injector duty cycles, get a fuel pump, 850CC primaries or 1300CC secondaries, dyno tune, and maybe a Blitz Dual Solenoid Boost Controller, and an intercooler and with a dyno tune you will be making 30-60 more RWHP depending on how much boost you run. Your clutch probably isn't doing too well with all that power either. Also what size/kind of tires because traction could give you a bigger advantage as well.

This should be in the Kills section but while we're discussing it, really if the '03 Cobra wants to eat up people in the 1/4 they should go to 393 or 411 gears in the rear instead of the taller stuff they come with stock.
If you get a good tune on your PFC, setup at 12psi and 11:1 AFR you should be able to give him a good run for your money. You'll want to do some data logging though and check your duty cycle on the injectors at that since you have a MP (from what I've read).
To go above where you are HP wise you need to do injectors, fuel pump, radiator, and IC. You can then go up to 15psi on the twins (though I wouldn't drive around always on that setup, run a 10-12psi map for daily use and 15psi map for when you want to get on it).

You can go from 210ish RWHP stock up to around 300rwhp with just "bolt-ons". Thats a pretty hefty increase especially when you look at it percentage wise.
The Cobra going from 385ish RWHP stock up around 475rwhp with bolt-ons is the same 90rwhp gain but it is less percentage wise so the 'butt dyno'/track timer will notice less of a difference.

Those new cobras are beasts, but good run . I raced a 98 cobra last night. I was even with him but he got away because i have that stupid fuel cut problem at 5k rpm!!

Dont get me wrong I love my FD and wouldent trade for the world. But if you think the 7 can never lose and to a slowbra of all things your are just plain ignorant. You can make all the mods in the world and in the end it comes down to the driver. Pratice man, hit your shift points and side step your clutch. If you had at the get go you should of had him in the end. Not to say that his shitstang didnt just have more power. You sound like you never want your 7 to lose. If that is the case choose your races more wisely and just race the rice. When you step up the LS1 and stangs and other high HP production cars I recomend that you buckle up.

i don't think you wanna get into a pissing contest with the guy like Jasil said they dont need nearly as many mods as we would to get to those levels. if he is gonna stay with just the intake and exhaust then like every1 has suggest a good tune should get you where you need to be.
do you ever go to the track? i would like to see both yours and his times. that truly tells the story of why you are winning or loosing. what i am saying is he may have only beat you by one car length because his skills aren't where they need to be OR maybe you are both driving the cars at their limits and it is a true indication of one car vs another. get what i mean? it is hard to know why you win or lose on the street.
say for instance a cobra with his mods & a skilled drive usually runs 12.5s, but he can only manage 12.9. Then it is not a true test of the cars ability, but that of the driver. with solid #s it would be easy to tell how well both of you are driving the cars. you may be milking every ounce out of your FD while he is only getting 8/10ths out of his cobra or vice versa.
in other words driving skill can have a lot to do with the outcome of a race and the only way to measure your skill is by finding out what ETs other people with your same mods are running and then figure out why you arent running those same times. if you are then you have reached the pinnacle of drag racing success and modifying your car is the only way to make it faster.
taking it to the track is just a suggestion, obviously, it is your car and your life. i am just give my one and a half cents.

svt squasher I noticed on your sig that you want to get an ls1 F-body. Why would you want to downgrade cars? Is it the cost of ownership? I would personally have a hard time going from an all around awesome car like an FD, to a plastic rattle-trap GM, but thats just my opinion.

the problem is our FDs started with a relatively small amount of power and is only saved by its light weight, yes you get more proportionally, but you need more to get to where these guys are already. get what i mean?
they have a full 1 to 1.5 second advantage over our cars from factory. that means you have to make your FD 1 second faster just to catch up to a stock cobra; it is like starting a race with a handicapp.
the truth is the cobra is designed to be a straight line powerhouse, while the FD was designed to be a back road burner. can you make the FD perform as a drag car? the answer is yes, but we knew that since we have seen 11 second street civics. meaning, you can make just about any car perform if you are dedicated enough.

I see no reason why you can't get the either car into the 11's for close to the same amount of money, they both seem to require about the same mods to get there, except with the FD you need to step up to a standalone EMS.

if you can get your 7 to run 11.8s on street tires(and i mean more than one time) with whatever is the FD equivalent of:
2.76 pulley
Steeda CAI
Accufab TB
LFP Heat Exchanger
Magnaflow catted x-pipe, catback
Predator custom tune by RWTD
which is the equivalant of about $2000-2500 in mods then i wanna know your secret.

hi I was the passenger of that race, rx7weee wanted to see where he stood up to the stang. that cobra suffers from bad wheel hop so he just dosnt drop the clutch it was a good race ive seen the cobra race before and its no slouch but rx7weee kept up pretty good and with a little more work there shouldnt be a problem.
"personally I think that SC just sounds really annoying"
it sounded F#&king wierd when he was right next to us with the window down and was at full throttle. wasnt a sound i would expect from a SC. I cant even describe the sound.
