New 03 cobra drag times

Disco · Oct 30, 2006

After i retuned my buddies 03 cobra 3 weeks ago adding a 4lb lower pulley to his already 2.8 upper. The car ran yesturday at island in nj 11.05 at 125 on the et streets and skinnies. Full exhaust and it has stock intake and stock maf and stock tb and no cooling mods or cold air. The car is just amazing on the strip. The tuned is not even a race tune, very safe af on the street 11.6 too 11.8. I do sct tunning in allentown pa, funny part i think this car dynoed less hp then all the cobras i did. So down get down if your car does not put a big number down.

Imagine what the car would do if he had the blower ported so it could maintain all that boost in the upper RPM's!

forget the blower porting what about a throttle body and tweak my safe tune a hair. This car is going pretty fast considering. There is alot more in the car before we get to porting.

True, but the stock M112 Eaton is notoriously inefficient at those high boost levels and I guarantee you're not holding that 16.9lbs (4lb lower + a 2.80 = 16.9lbs) all the way to redline. 16lbs is the maximum recommended boost level even for a ported setup. All you're doing is making a butt load of heat running that blower unported at 20,000RPM's!

IMHO I wouldn't waste your money on a TB at this point. The stocker is good to well over 500RWHP. The biggest restriction in the intake path is the stock airbox/filter assembly. You may see a little better throttle response with an aftermarket TB, but many people report minor idle & cruise control problems after installing one. If you just have to have a new TB go with either an Accufab single blade oval, or a Billetflow if you can find one. Amazon Racing is also in the process of testing a new TB, but hasn't released it to the public as of yet. Stay away from the BBK twin bore.

If ANYTHING I'd add a good straight through CAI (K&N FIPK or a JLT RAI) and a cat-back. Those two mods alone will net you well over 40+ RWHP.

For $745 you can have the stock blower, inlet, and throttle body ported by Stiegemeier and get yourself another 60RWHP without a re-tune.

And your car runs what? My point of this matter is how fast you can go by not spending alot of money and buying ever single part that someone has for sale. Im a huge work with you got type of tunner. Most of the time driving is worth more then the 500 dollar part one puts on. Just saying people can go fast if they dont have or want to spend a lot of money on parts some basic items can do the trick

Gee I wonder how I missed your point? Must be because you never told us you wanted to go fast for cheap.

My car ran a 12.5@114 with only a cat-back & a CAI. I still run the stock pulley/boost. My car now has full exhaust (headers/x-pipe/cat-back) and a K&N FIPK, but I haven't been back to the track. That's the extent of my performance mods.

Look... if you want to do a budget build up that's fine, but next time you may want to tell us that before you ask questions. We're not mind readers around here. I was only answering your questions with honest truthful answers. Please by all means, go out and waste a few hundred dollars on an aftermarket throttle body. No sweat off my balls. There are cheaper mods which will garner greater gains than a TB. If you want to know what they are just ask.

I have an idea...let's throw a thread out about good times, ask a question that is as clear as mud, then be a smart @ss to the guy trying to help you out.

AND....I need to see slips because I am calling on those times with just those mods, stock weight (unless you are leaving more info out). 125 mph is insane on a upper and lower only car with no other mods. Mph is a measure of hp, not driving skills. 125 mph is over 500 rwhp. With the mods listed and no port, I think this car might make 450-460 at the tires.

I think UM's advice would be great to take. a 2.8 and 4# lower will do more damage to the motor in the long run without a port and supporting mods. Any tuner should know that.

Disco · Oct 31, 2006

thats why i keep the car af no higher then 11.8 on the street but you have to remember the guy that pilots this car is worth about another 50hp and probably thousand bucks in mods. This guy knows how to drive.

He was a relatively new member and I didn't want to raise the BS flag on his boys times, but you're right of course. I don't think Bob Glidden himself could pull an 11.05 with just an upper & lower and no other supporting mods. Maybe it's that ultra rich A/F ratio that makes the car so fast. I guess it's safe for me to say...

I don't believe it.

Everybody remember what the Disco man says, "So down get down if your car does not put a big number down." WTF? Is that even english?

well its true as mentioned long tubes xpipe cat back those pulleys and drag wheels. et streets we are running too.

wow i dont think id come on here and call out UM like that. he knows his **** better than 98% of the half assed "t00nerz" out there.

fact of the matter is you can make more power with less boost if you have more airflow capibility. if you were any kind of tuner, youd know that airflow is what makes the power, psi is just how it gets there. running the right setup within its efficiency range is gonna make more power and be more reliable than running something out of its efficiency range.

just think of the timing you could run if you didnt have to retard it cause the heaton was throwing so much heat in the mix. probably would be smart to upgrade the heat exchanger and resevior to help in cooling the mix even better.

i dont understand why people just throw boost and "tuning" at a car and totally forget about the all important support mods. id hate to see your duty cycles with a 4lb lower and 2.8" upper, probably running them close if not over 100%.

btw it sounds like you have a good driver. put him in the seat of one of the cobras putting down more than he is and see what happens. better yet, spend a little on support and see how much better it gets.

well our goal was around there or 10.9 with the eaton and it shows how well it works. Without spending the extra money. WE dont race in the summer only on the cool fall. As tunning goes every guy that comes in should not be socked with well you need to buy a new blower and this and that and you know what before we tuned cars we were sold parts headers too who knows what that did nothing for a car so. WE are divided into two groups the ones that work with what they got and go fast and the ones that buy everything and do not go much faster. Its a shame you all take offence on this thread.

Uncle Meat · Nov 1, 2006

We don't take offense to the thread or subject matter as much as we take offense with your attitude when someone tries to help you by truthfully answering your questions.

Disco · Nov 1, 2006

I never really asked a question if i did it was kind of to myself about tweaking a tune and adding a tb just to get that push into that 10.9 which i know whould of worked.

Here, let me refresh your memory...

If you know for sure that an aftermarket throttle body added to a completely stock intact tract will generate enough extra HP to drop almost 2 tenths then go for it. It sure would be a hell of a lot cheaper and easier to just add a cold air intake which is guaranteed to give you a proven MINIMUM gain of 15-20RWHP on these cars. Evidently you know better than all of us so why even come on here asking us?

I didn't take offense, I just spoke my mind and called cow poop.

I also stood up for UM when you posted your "And your car runs what" comment.

Not a good way to start off on a new board.

Im the 03 cobra owner. I always post on svtperformance and disco (tim) told me about this post. I have a big k/n filter but a stock intake tube is what he meant. Sorry for the confusion. Dyno #'s are dead on. A/F is actually 11.3-11.6 when logged on street. Read the posts on svt.

Tim's GT runs 11.9 @ 115 (1.61 60') with a last dyno of 365rwhp through a stock catback. This dyno is dead on.

All runs at Island Dragway..if you guys know the north east/midatlantic this track is not the fastest track around.

I do not consider myself a pro driver just hitting right shift points and getting a decent 60'.

Here is the link, thanks guys.

The car lost 7hp and a ton of peak hp with the 4lb lower over the 2lb lower. I took the torque gain (32rwtq) and lowered my shift points to around 5800 give or take a few.

I keep forgetting I do not have an icebox, car is still running factory heat exchanger.

Car has spare/jack removed, drag wheels, full factory interior, sway bar on front end links taken out.

those are good times. Thanks for providing the proof. Your buddy needs to calm down though. You have to see where we are coming from seeing a noob post up stuff that just didn't add up and then starts being a smart ass.

Anyway, great numbers. You can drive very well.
