i was watching horse power tv last weekend and they bought on a 03 cobra
and did i hypertech tuning and pullies on it and they got 426 rwhp or crank horsepower out of it.(don't remember it it was rwhp or crank)

i was just curious cuase i might be gettin a termi next year and i was wondering if A full magnaflow cat back and jlt cai and maybe a new pully would produce about the same amount of or hp? or more?

Full exhaust, CAI, Pulley and a tune.. you can definately expect 430-440rwhp. Depends on the dyno really... you might see higher numbers, or lower numbers.

[KingChronic]

those are actually pretty low numbers. they were using a hypertech which isnt very good, and probably also a canned tune.

a 03 with a intake, and catback will typically lay down 400-420RWHP alone. a 2.80, or 2.76 upper pulley, and a good mail order tune will give you 440-460RWHP.

we actually have a local guy running a 2.76 upper, O/R X, catback, intake, and a tune and is making 498RWHP. and that has been on a few dyno's, just a very strong running car.

Ive seen so many different numbers from just a pulley, tune, exhaust and CAI. It gets aggrivating after awhile. Most chassis dynos are calibrated differently, and some are just plain inacurate. 430-440rwhp is a typical number from what ive seen, and the engine i was going to put in my fox laid down 448rwhp with just those basic mods. The numbers could be higher.. as i said, depends on the dyno.

Here is the real answer to your question. Yes they are that Bad Ass, no they are not as good at drag as a GT with the same power( IRS vs. Solid Axle) and yes, if your dad finds out, there will be no way you will get one.

hehe funny thing is he said that he will buy me one as my first car for graduation if i can find a good one with decently low miles and as long as i buy the mods like i do now he doesn't care aslong as they are simple bolt ons the muffler shop can do or i can do

Also i know some of the 03 cobras problems with the block or heads or somthin and just curious cause they said on show that the ones made after november 1st 2002 or 2003 (forgot what year they said) were ok.

some of the early 03's had the head tick, which came from the valve guides on the driver side head, and sometimes both.

there hasnt really been a engine failure because of it, its really not a big deal, jsut a extra little tick. the the valvetrain noise on the 4V motors are so loud anyway you really dont tell that much.

my 03 was a early sept 02 build, and had no problems.

also, ive seen many 03's dyno, and never seen one with a pulley, catback, intake, and tune dyno below 440RWHP with a upper pulley. they almost always dyno 440-460RWHP on average, then sometimes even higher

i personally think they are the 8th wonder of the world.

lol thats why i'm gettin a B-O-B Termi and puttin a full magnaflow CB JLT CAI or RA and maybe a pully and if i save enought money i'll get KB Supercharger and a 91 octane tune

lol thanks king for helping me steer clear of the challenger SRT8 and pointing me int he direction the the terminator lol i found out how heavy those things will be (4100lbs+) and they have the Charger frame and suspension

O btw whats better on the termi CAI or Ram air?? cause i saw some vid that a guy put a ram air kit on his cobra.

i think you would have gone in the right direction without help.

you can do either. i use a RAI for a few reasons 1, its right in the engine bay, and is easy to see, and get to, to change the spark plugs it doesnt take you 30 mins to remove the intake. 2 ive had bad experiences with the CAi with the MAF, and filter falling off in the fenderwell, and causing the car to stall, and 3, the RAI supports more power than the CAI. you can get a high boost CAI thought that will support even more but i still dont like it.

theres also talk about if you drive your car int he rain alot, the CAI can pick up alot of water. but ive personally never seen any damage from it, but im not sure.

no, the regular CAI puts the MAF, and a 6" S&B filter in the fender, the RAI puts a 9" S&B filter int he engine bay, and the high boost CAI puts a 12 filter in the fender, then the MAF up closer to the TB.

k thxs

what kind of RA do u use
cause i was thinking bout putting a jlt on it

and i've been reading alot bout the rear axle on the termi(its IRS) and how alot of guys said its not really good for dragging and there saying that the GT's solid rear is better
want to know what u think??

That's true, but the IRS is much better for handling on the street.

but is the IRS still pretty good if i still wanted to race my buddies from a roll or from a stop on the street??

The IRS is known for it's wheel hop from a dig. Unless you are a drag strip weekend warrior, don't worry about it. A termie doesn't have many issues beating most cars.

the IRS is a toss up, its great for blasting down a highway where the road is uneven because of how well it responds to eneven surfaces.

a IRS can also be damn good at the track. the main problem that needs to be addressed is the pumpkin, and the fix is a $150 IRS brace.

after that, yes there are alot of people that blow halfshafts but alot of times its there fault. you DONT go to the track with 17, or 18" DR's and launch hard when you have 500+RWHP you going to snap a halfshaft, because its going to hop, and the sidewall also isnt goign to flex to cushion it.

you can also pop regular axles in a solid like that too.

with a good set of big sidewall tires they can launch with high high power. but eventually the halfshafts need to be upgraded.

even the level 5's like i have can pop if you hop them.

nothing wrong with IRS except for the added weight, it adds about 150-200LBS over a setup solid

there are cures to wheel hop. the best first mods to get rid of it, is FLSFC's, and a set of nitto DR's sidewalls are a bit softer, and will help absorb shock.

then from there for getting rid of hop you get into replacing the bushings, UCA, LCA, IRS to chassis, and pumpkin bushings which is like $550 for the kit, and liek 800 to install (its no fun, the WHOLE IRS comes apart).

after that hop is non exsistant, you have as much of a chance hopping a solid.

so basically if i'm going to be the occasional street warrior and i want to decrease the event of the halfshaft braking i should get the Irs brace (o and also is it 150 for each side brace or is it 150 for a set?)
and i don't really think i'm going to be going to the the drag strip every weekend so i don't reall think i'll need the dr's be mostly running on street tires...
and like i'm not really going to be racing all the time i'm mostly going to drive place to place and if i do race its either going to be against my buddies or some random guy that wants to or i want to.. but do u think if i just the ocassional street race my irs won't break on me if i don't like drop it hard like i'm at the drag strip. if that makes any sense(tell me if it dosn't and i'll try to refrase it)

the brace is a brace that goes on the diff cover so it doesnt crack. it can crack at stock power, or it may take a little while. but its a cheap and easy mod.

it will take alot to break that IRS. my old cobra with 650+RWHP was on the stock IRS, and i never had a problem, and i beat the hell out of it, no bushings, nothing, jsut the IRS brace.

one thing youll find that even stock power isnt like driving a normal car, its just not going to hook on those stock 275 goodyear F1's, they suck ass.

a good street tire for these are the 315 nitto DR's. they fit great on the stock 17X9's, they hardly buldge. the nitto 315.35/17 runs a bit small. so small on a 17X10.5 the rim actually sticks out past the tire.

but the nitto 315 DR will hook good, give you 10-20K miles depending on how you drive, and you wont be able to tell you have a DR on the back. they evacuate plenty of water, yet still give a good hook.

i drive around wtih 315 hoosier DR's which is a DOT slick with 2 small lines going all the way around it. i wouldnt recommend that though. if the road is damp pretty mcuh you have to pull over and wait for it to dry, or have somebody bring a trailer.

[Fastback91]

this is a stupid question but
are the 315's a good all around tire mean like will i beable to drive in the rain ( like turn around corners when i'm regular driving)and will they turn pretty good for normal driving in the rain and how much do the usally run for 4?
