sounds like fun. i'm jealous.

Just changing a pulley on a 03/04 Cobra without retuning the ECU is asking for a melted piston. At the very least the MAF transfer table needs to be rescaled. Once you go over 14 psi (eg anything more than the stock blower with the smallest pulley) it gets really tricky because of a EEC-V hard coded max charge air value of 1.9 that clips anything higher. Then you have to lie and hack all over the place to keep things under that (like specifying injector size smaller than what you really have because you have a fake load curve that maps 0-2.5 into a 0-1.9 scale). Tuning is extremely important. The stock fuel system is good to about 600 RWHP volume wise.

I wouldn't track a Cobra without redoing all the suspension bushings and mounts, both front and rear, and without a set of weld in sub frame connectors. It's a totally different car. The stock bushings are too squirmy and even just spirited driving on the street you can't always feel where the car wants to go. With some good tires you can really feel the body trying to float away from the suspension under hard cornering. This is one of the many areas where SVT lost the argument with the bean counters and was forced to go with less than desirable. IMO the only thing that should be moving relative to the body of the car are the wheels and the control arms. Interior panels rattling are normal and to be expected, the suspension clunking and creaking through powdered rubber bushings under load is unnerving. A higher, fixed ratio rack and solid u-joint steering shaft address the usual complaints of numb or sloppy steering. YMMV.

Dude, you constantly bring in all sorts of 'geek' to a thread where most only need layman's terms. Getting as specific as 'powdered rubber' is

Being that you have / are looking to do all these mods to your car already yet don't 'race' would explain why you'd rebuild the entire suspension prior to any track day.

The Cobra stock is more car than most will be able to push as is.

Tons still have the IRS and 10 second slips. Some went with the solid axle swap however as it supposedly provides better launches and saves about 100 lbs.


I think you misunderstood what I was saying, I was trying to emphasize most everyone tunes their cars, especially with Cobra's. I know a flash is a tune, jesus fucking christ. I have "flashed" or "tuned" several different cars that I own. It's all the same thing, it changes various settings on the ECU, people just like to call it a few different things.

Either way, we should let this guys topic get back to what it is...

lol, nah I like where its going. I just opened it because I was excited to get the car back -- I dont care which direction the thread takes. And also, I like a friendly argument (debate?) and certainly agree that a better (cheaper) path to get this power level would be through a Mustang or similar V8, but Im not really concerned about hp. I just know that most people that dont appreciate cars at the same level as an enthusiast (car nerd?) like to know that stat only pretty much.

 

[bananapeel42]

I personally think STI's are badass cars. From what I've heard it just takes a lot more money to make highend power 400 + to the wheels than say a comparable V8.

I wouldn't mind owning a late model as I hate the new body style.

Not most are swapping ECU's and/or dyno tuning. Many are. Most are bolting on shit and leaving it to chance.

I don't think you have had as much experience with cars as you are claiming esp saying you have tuned several you owned.

Be able to flash is awesome, but not too common.

What happens is a person more or less gets a 'capable' car and then they think they are experts in the field.

solid axle has nothing to do with 'supposedly' a better launch...there is no debating it.

There are never 'tons' of 10 sec cars anywhere.

It's more about power to weight...the mustang is around 3700lbs or more the STI closer to 500lbs less than that. A car like my 240sx is about 1000lbs less.

The GTO many love is close to 4000lbs.

Add into that gearing.

In the end the costs end up being close. You have people like yourself thinking their 390hp terminator can be 600HP for a 'thousand' or so.

Last I checked it's about $5k to do it.

Also the first thing I laugh about 10sec cars is how everyone has one they 'bring to the track', yet you never see any with the required roll cage.

 

[bananapeel42]

I never said it took 1000 dollars to get 600 HP. Where did I fucking say that?

I said I spent 1400 dollars to hit 480rwhp and 500 rwtq. You don't SWAP your fucking ECU at all.

I had a dyno tune from HPP Motorsports using an SCT chip to modify the stock tune on the car.

It would take about 5000 dollars in purchasing brand new parts to get to 600HP reliably, that is correct at least. The main cost is purchasing the KB or Whipple supercharger which will run you above 3k.

I also didn't WRITE my own tunes. I purchased a custom tune for my car from a reputable tuner then used that file to write over my stock tune with a handheld device that plugs into your OBDII port on your car.

Jesus christ it's like talking to a 3 year old, you pick out 1 word from a sentence then neglect to read everything else.

There is debate on the launch, I know of people who have done the swap and their 60 foots actually increased. There is no denying that it saves 100 lbs and can drop you by a 1/10th in the 1/4 mile from that alone.

Just read you have a 240SX, it all makes sense now. GTO's don't weight 4000 pounds either

 

[alkemyst]

What does a GTO weight? 3800? close enough. Also I doubt any of the above cars are doing it for $1000 or so like you imply. You said it would be cheap also....

You are a wannabe in that crowd and probably don't have the kit you say anyway...it's impossible to have it and not understand these basic concepts.

You bought a flash even...have you even been to a freaking dyno to set up your car or just 'guessing' on the power?

 

[bananapeel42]

Ok, I'll post pictures of my car and the dyno sheet from HPP if you leave these forums.

I didn't buy a flash, I bought a tune for my car, which pretty much everyone pays for. A select few people actually write their own tune files. You obviously don't know dick about American muscle cars and have a fucking POS 240SX probably stock and beaten to shit.

The Dyno made 456rwhp / 484rwtq BEFORE my ported blower.

The 480rwhp / 500 rwtq numbers are conservative from my port job as well.

So, the mods on the dyno were JLT CAI, SLP Loudmouth I catback, stock midpipe, NGK plugs gapped at .032, Steed 2.80" pulley with a billetflow 100mm idler + bracket.


If you'd like to look up the pricing for those mods on various websites go ahead. I bought most of that stuff used, but check the NEW prices and see how much that totals up.



http://s317.photobucket.com/al...current=CobraStuff.jpg

It was a Dynojet dyno btw.

I HAVEN'T IMPLIED IT TAKES 1000 DOLLARS TO RUN 10'S IN THE 1/4. WHY DO YOU KEEP SAYING THAT? JESUS CHRIST.

I ORIGINALLY STATED I PUT 1400 DOLLARS INTO MY COBRA, HOW IS THAT IMPLYING IT TAKES 1000 DOLLARS TO RUN 10'S. FUCK YOU'RE DENSE.


All of those people on the list don't have an aftermarket blower, they have supporting mods, but that's it. Most, if not all of those people on that list spent under 5k by a good bit to get their cars in the 10's.

 

[alkemyst]

Breathe a little Francis...

Once you dyno your 'porting' you will know for sure if you netted nearly 10% to the wheels.

You said is was cheap and easy to hit 600WHP in a V8....

You said ton's are running 10's.

Like I was saying..you are painting this with a brush like this guy would

Nice -- hey your picture doesnt work for me and Id really like to see your car. Can you fix it? Also, what are stock cobras putting down on that dyno? Im sure you know as well as I do that dyno numbers are essentially useless as different dynos will read wildly different results.

 

[RGUN]

Hey Alkemyst, Im a huge fan of 240's, I was looking at one really hard before I bought my car. Can you give us some more info? pictures perhaps?

THanks

 

[alkemyst]

I just have my basics up at http://driftkat.com/98SEmine.php

Should be march for engine mods. Still planning, everything else is done. Going to finish up CCNA (next week) then CCNP...i have a pretty nice job waiting for me once these are out of the way.

I am only shooting for 300/300 maybe 350/350 to the wheels...daily driver with full boost by 3000-4000, GT2871R/.64. SR20DET, JWT S3 cams, 70mm TB, Enthalpy tune, 550's, Walbro 255, Koyo radiator, Greddy Intake Manifold and intercooler, 3" downpipe, etc. About a $5-7k build. The engine/trans are actually the cheap part ($1600). That's into the 11's on drag radials/MT's...easy 12's.

Thanks...most here think it's some freaking beater anyone can find. Took me months and months to find and even then it was hundreds of miles away.

It's like the same with the WRX/STI crowd down here...every Vette/Cam{b]e[/b]o/Mustang think they can take them because "you jus' gotz a four in dar".

Personally I couldn't handle seeing my same car at every light/parking lot/etc like those domestic guys can nor deal with the piss poor interiors.

I am definitely aware of how difficult it is to find an 97/98 in good condition, let alone a manual trans. They are one of the best looking cars on the road and just a very capable car. I would love to pick one up if they just didnt still demand such a premium.... FandF has not done those poor cars any favors either, a lot of them are all hacked to shit now because some highschooler got one and wanted to 'fix it up'

Nice find, keep it looking clean too -- dont put those huge boidy kits on, they are dead sexy in stock form.

 

[alkemyst]

true...some car guy with more money than most out there said something like people mostly think of these cars as the old hatchback style driven by some 16yo with a 4' wing and a draging muffler....

One dude here tried to claim he tracked one and the whole body felt like it was loose. It's one of the better chassis out there for both balance and rigidity.

I am keeping the body stock...wheels will be an upgrade once I know how bad traction is and everything is dialed in. JapTrix down here has done a few WRX/STI's that are pretty amazing, they are one of the only shops with a Mustang 4 wheel dyno (http://japtrix.com/dynotuning.html)

Well this thread turned real quick. Anywho good luck on the build. I wish I could afford a bigger turbo. I'm stuck with my crappy small stock turbo. Boost is addictive. It is my DD so I should keep it conservative but hell....

Ahh come on man, you only live once and mine is my DD as well -- thats another reason our little 4's are better (and I say this with a degree of humour, so nobody flip) than supercharged V8s. Ill have 600hp on tap, and still get 24+ mpg

You're ganna DD that??? Man I don't have to guts to DD a car with that much power but I do love that with big turbos come better MPG.

lol, while I would love a vehicle like that (power/weight wise) I am doing my absolute best to turn the exterior styling into that of a family sedan. Im looking into scoop deletes or revese scoops and a new trunk.

Scoop delete should be easy as you'll be using an FMIC rather than the stock top mount.

Can you recommend any? Ive been thinking about the KSTech delete, but Im not sure the look suits the '07 body style. The only other once Ive seen is the Seibon reverse, and its not really in line with my subtlety goal.

Also, do you happen to know if anyone makes a delete package for the rear window roof mounted spoiler? Ive been looking without success for awhile.

Not really. Mine was a GF body, HERE.

While 600WHP is crazy, there are Honda's with that being DD and they are really pushing limits.

All it takes is money for spares .

My friends 350Z is making a ton of power for autocross and series racing...it's a puck clutch. Once you get it going it's a blast, but in stop and go REALLY touchy. Screw driving it in the rain.

 

[bananapeel42]

I didn't have time to get pictures up last night. I can get some tonight or Friday. So that Dyno chart works for no one?

Dyno's aren't essentially useless. The baseline for most Cobra's is around 370rwhp, 360 rwtq.

They are great for measuring power gains from various mods and can give you an idea of what your car should be capable of.


Obviously you need to go to a good shop with an experienced tuner with a goo calibrated dyno, which I did.
