since the 99 and 01 cobras are rated at 320hp, would it be safe to assume even swapping on stock 01 cobra heads, cams, and intake along with headers and a full exhaust and tune should be a minumum of 60 hp increase on our cars ?

What car is this for? While I would say you should be able to realize a 60hp gain with C heads/Cobra intake/headers/exhaust there are easier ways to get there depending on what you are looking to achieve. A shortened runner 96-98 Cobra intake will get you close to 40hp but with less low end torque then a C head motor will make. If you already have gears/high stall TC it might not matter to you much and just the intake install is much less involved then doing the heads too.

how do you get one with shortened runners ?

its just going to be a daily driver but it may see a turbo one day

I bought my cobra intake manifold with the runners already shortened. But there are many speedshops that if you bring them a factory one will modify/shorten the runners. Mine made about 35 Wheel horse power more with the shortrunner and mods in my signature. it made 245rwhp at 6800 rpm.

Worth it!

I wonder how much the intake manifold alone added... ive got similar mods to your car but have that dreaded gen2 intake manifold. Ive been looking to get a cobra but havent found one yet. Ever ran your car at the track?

for my plans the 98 cobra intake should work fine. i will do some research on that. arent used ones around $400 ?

Less than that I would think. The 1999+ style ones seem to fetch more. I would not think you would have to spent any more than $300 and probably less.

i normally see them around 400 theres more demand for the 96-98 because its the best intake for b heads

True. But B heads are being worked on less and less. C head intakes go for $500+ now.

whoa whoa.... what ?? your car only dynoed 210 rwhp stock ? u lost 70hp through the drivetrain and then only dynoed 245 rwhp with those mods ? all those numbers seem low to me and thats alot to lose through the stock drivetrain

2nd gens are known to have less then advertised hp

wow that sucks

what do the 93-96 models usually dyno stock ?

stock automatic drivetrains lose usually 22-24% so it is close but a little under what stock should be

sorry guys i am a little late on this one..


The dyno i went to was newly set up and was not properly calibrated. It was a dynapaq and they dyno'd a stock one right before mine to compare. 245 HP is good. It seems low but it could easily be 260-270 on like a mustang dyno. you never know. it pulls like crazy.. but yeah i would have liked to see an actual calibrated dyno do the pulls but for tuning you are just looking for increase or decrease after changing values. I also had 4.10s installed which supposedly you loose dyno horsepower off of.. either way im not a numbers guy, im an addrenaline guy. and my car gets me going every time i hit the skinny pedal!


I have never ran my car at the track..

come to cordova next friday night (see midwest forum)

I would, but i am still in the process of doing the one piece driveshaft.. getting the 93 one balanced and putting it in.. kinda running low on $$ this week.

yeah i got all kinds of stuff i could toss in mine but just no time, before the meet so ill be runnin stock again......but who cares!!

Just has a killer vibration at 65 and gets worse as you increase speed. i think by the end of the quarter mile it would be vibrating bad enough, i would be worried about it.. i would just rather not drive it at highway speeds with the vibrations.

Just put a whole motor in it. heads would be too much trouble than their worth even if you pulled the motor.
