Exactly, and he has a 300lb system i believe!!

 

or you can buy an 03-04 cobra (20-30K used), get a 7K hellion single turbo kit, $1000 for slicks and skinnies, 3K for misc items (fuel, maf) and run 9's @ over 140 on the stock motor.

 

yes u can do 10s on a stock motor... but not for long. Ive seen it.
I bought the evo for $4.5K on an auction... stripped it.. fixed. it..... for under $12K... then put the best stuff in it.... and still came ahead ... I didnt have to spend $1200 on the IC, I didnt have to spend $850 on a Sheppard header. I didnt have to get a Autronik stand alone, etc..... and I would still run 10s... but my friend... I DRIVE THIS CAR EVERYDAY and at 24 miles to a gallon u cant beat that... I drive to and from the track- 60 miles.. and I beat up on low 10 second mustangs that never see the street. thats the difference my friend. not to mention... no one expects a stupid rice rocket to do 10.2s...
My friend has a low 10 second trans am.... he gets 6 miles to a gallon....

 

03-04 cobras are far from n/a fat cammed ls1's. I am talking about the stock motor, stock cams, stock piston/rods, a single turbo kit, upgraded fuel system, and 20# of boost. The are tons of people that drive 9 second cobras all day long and pull 15mpg on the street and 25 mpg on the highway. OBTW this is all done on pump gas. And if you're questioning the stock motor...the 03-04's come with a forged crank, forged pistons, and forged rods. The pistons are the weakest link, but many people have them over 800rwhp without any issues.

I know evo's are bad, my buddy has an mid 10 sec one.

back on topic...9's in a porsche is gonna be EXPENSIVE.

 

Fact is, both of you guys mentioned awesome cars for modifying and going fast. Love the Cobra's and Evo's!!

 

dont dissagree I dont know much about cobras.... I do remmber someone staying that they run 9s on a stock mustang motor and everyone laughed at him... if I recall correctly.... I dont remember....
Yes a 9 second TT is almost impossible... ist not meant for it...
on the highway its a whole different story...

 

the fastest stock motor pass was a 9.1 @ 152 way back in 2004. Since then everyone has been modifying motors to make more power so they can run quicker.

 

Yes, but back when I was running 20lbs of boost in my mustang......600ish HP was pretty much considered the limit for the stock block (302)...more than that and you were keeping your fingers crossed and waiting for the inevitable.....has that changed with the new motors?

Chris

 

the modular 4v motors are a far different breed from a pushrod 302. 20# of boost from a turbo is good for 750-800rwhp in a 03-04 cobra. Just the 03-04's have seen live over 900rwhp with stock motors...600rwhp is definately a save number to stick around, but there are plenty more people way over that on the stock block putting around.

 

WTF that';s absolutely insane, Supra's cant even go that much on a stock block/motor?!? I find it hard to believe quite honestly. Im sure most cars can do it but they blow a minute after achieving the power, these are daily driven, reliable??

 

if we are talking about daily driven (10k mi/yr) cars that are running 91/93 octane, the limit for a turbo car is ~700rwhp or about 15psi with a supercharger the limit is ~630rwhp. If the owner is running race gas (100 + octane unleaded) the limit is (daily driven) ~850rwhp (22 + psi) on a turbo or 25-26psi from a supercharger ~700rwhp. If it's a track only car you can run on the upside of 25psi from a turbo and make over 900rwhp on the stock motor.

Granted people have popped motors with less HP, it's all in the tune and the driver. I popped a motor at 580rwhp in my 03 cobra b/c I went to an idiot tuner who left my car with too much timing and running lean due to a saturated MAF.

here is a list of some of the fastest 03-04 cobras out there. This list does not include many, many low 9 second and a couple of 8 second 03-04's because the only way to get on the list is to post your time in that thread, which not all do. The ones highlighted in blue are ones that I know for a fact are the stock motor, some of the others might be, but I don't know.

you can see at the following link some turbo'd 03-04's and their rwhp. The cars with the 281ci motor are still running stock. http://www.modularfords.com/forums/t...ata-33758.html

 

Wow, damm they are fast!! Seem's like one of the best bang for the buck hp per $ wise no?

 

the 10 second cars...
on slicks running those times correct.
are they spraying...
and with 1.4 60 fts... the axles/ suspension handles all that load???
and ur saying that for a few thousand dollars this can be done...
what about the programming- stand alone???
fuel system- I dont think a stock set up can handle 900 rwhp.

 

it is a very good $/hp ratio when modded. Hell even stock they are ~360-390rwhp.

 

some of the guys are on slicks, some are on drag radials.

The mods of the people are listed next to their times...some are spraying, some are not. Look for an N next to their time.

Only a couple of people have pulled 1.4 60' times on the stock IRS. I have busted off many 1.6's on a 100% stock suspension with 275/40/17 bfg drag radials on my stock rims, that I drive daily on. Drive Shaft Shop (DSS) offers level 5 half shafts for the cobra rear ($1500). They rate them to 900rwhp. Only one person has broke one DSS shaft...he was running 700rwhp and 750rwtq and dumped the clutch at 6K. He had made 100 + passes at the track with the same setup. If all you want to do is drag then a switch to a built solid axle from a mach 1 or GT is the best move ($3K when all is said and done), this allows much harder launching with less chance of failure, it also drops ~100# from the rear of the car.

It depends on how fast you want to go. If you want to run 10.50's or better it is possible to achieve that for less than 5K. You would need: upper pulley ($125), lower pulley ($350), cai ($150), mid pipe (catted $400, not catted $200), catback ($300-700), ported blower ($500), nitrous kit ($600), custom tuning ($500), 60# injectors ($400), SCT 2400 maf ($250), KB boost a pump ($250), diff brace ($150), slicks and skinnies ($1000). Total: $4775. This setup is good for 500-520rwhp and 500-540rwtq without nitrous on pump gas and 600/700 + on the juice. The best time for this setup n/a is 10.89@127mph from a guy named broke7.

The fastest time that I've seen from somebody with this setup with n20 is 10.VENOMOUS03COBRA-1.51 10.30 @ 134.74 CFULDENP. There are plenty of other guys that are running 10.80 or better on similar setups; venomous can drive the funk out of his car. http://videos.streetfire.net/video/w...1B371025D8.htm

He is achieving that on a 60 shot, some people are running 150 shots with ported blowers, but can't drive like he can.

The fastest person with the same mods as John, but has a solid axle is 4. 03flamedcobra-------1.45 10.02 @ 139.59 CFUTDSERNP He is also running a bigger shot of N20.

Now if you want to have the power on tap all the time you can go with a twin screw blower (whipple or kenne bell) (+ $3100, but you wont need the ported blower (-$500) or the upper pulley (-$125). I'd keep the n20 for a rainy day. These blowers are good for 19psi on 93 pump gas and ~620-630rwhp 570-590rwtq. on 91 octane 17psi is max and is around 580-590rwhp and 530-550rwtq. With race gas 680+ rwhp is possible without worry. 23 + psi.

OR you can go with a single or twin turbo kit that is in market. I like the hellion single turbo kit. The kit starts at $6370 and when certain options are added it can approach $7500. With the turbo kit you wont need: upper pulley (-$125), lower pulley (-$350), cai (-$150), ported blower (-$500), nitrous kit (-$600). The twin turbo kit's cost more money, but seem to have issues with quality control. Another great thing about the hellion kit is that you can order it today and have it all within 2 weeks. I have yet to see one complaint about the quality of the hellion kit. The turbo setup is good for 670-710rwhp on pump gas (13-15psi) and 800-900+ rwhp on race gas (20+ psi)

the factory eecv computer is great to tune on. There is no need to change to a stand alone unless you want to run 1300 +rwhp. I don't think any body on that 1/4 mile list is running a stand alone. We have a couple guys over 1000rwhp (on built motors w/ turbo) running the factory eecv computer.

the stock fuel system is good for ~500rwhp. at that point you need to add 60# injectors ($400). at 550rwhp I'd add a KB boost a pump ($250)which is good until about 670rwhp. At that point you need to upgrade the fuel pumps to dual pumps either from the ford GT or Lincoln aviator, also upgrading the fuel lines, fuel rails and fpdm ($900). This setup here is good for ~800rwhp with 60# injectors and 920rwhp on 75# injectors (+ $150 over the 60's). If you want to achieve the safest 900+ rwhp, I would switch to a return style fuel system ($1500-2000) with the 75's or 96# injectors.

Now if it were my car and I was shooting for 800+ rwhp I'd definitely consider upgrading the pistons...which can be done for as little as $1000 for pistons and $1000 for balance and assembly of the block. The right way to do it is to have an entire short block built with new block, rods, crank and pistons. ($4000-5000) While doing that I'd switch to a 96-98 cobra teskid block which is aluminum. That block has been proven at over 1850rwhp in several 6 second race mustangs with block girdles. It also shaves 70# off the nose of the car.

Also, lets not forget to upgrade the clutch setup. The stock clutch is very stout. I have been running mine for 23K miles for which a good portion of it was over 600rwhp and it has yet to slip once. I have been sitting on a centerforce dfx clutch and aluminum flywheel for a while waiting for my stocker to take a dump. A clutch setup with the disc, flywheel, pressure plate, tob, and a upgraded 26 spline input shaft is ~$1000. The trans in these cars are very stout (same as a viper)...they rarely have any failures even at some crazy power levels.

I think this post covers most all of it. I am free to answer any questions that you've got. Oh and I never did mention messing with the cams or the heads...they are very good from the factory and if you enjoy maintaining a sleeper sound (IE no cam lope) there is no need to do anything to them. A fully ported set of heads with an aggressive cam will be + 70rwhp.
