just-agt · October 23rd, 2009, 02:14 PM

This might have already been asked but i didnt see it. What is the fastest times you have seen out of a stock long block 03\04 cobra motor. Any power adder or tranny. Thanks

There are guys on this site running low 10's. If I remember right, there are a few videos floating around of guys running 9's with just a twin turbo swap on the stock long block. It wouldn't surprise me any, especially since the guys running low 10's are doing it with the original Eaton.

A little off topic, but theres a gt500 in the 8's on the stock long block.

zigbigadoru · October 24th, 2009, 12:18 PM

what......how can those fatties get into the 8's?

maverick0817 · October 24th, 2009, 12:24 PM

sheet metal intake, twin turbo kit, c4, and a 9 inch.
My mistake they went 7's,. 7.94@173 mph. 1272 hp, 1043 tq.

Because they aren't that much heavier than a terminator and have a better motor

stangliter04 · October 24th, 2009, 12:40 PM

I am pretty sure the guy on SVTP that just went 9's with his Eaton is on the stock longblock.

that i just dont believe. not with an iron 5.4 and weighing more than the newedges from the get go. its really hard to believe that

maverick0817 · October 24th, 2009, 02:21 PM

Well theres also the fact a gt500 has a solid axle and a 03 cobra has irs. The car had full interior.

There is only 300 lbs difference between the termi and the gt500, it's a little bit but easily made up for

wraith beat me to it. LOL

huh i was always under the impression the s197 weighed over 4000lbs but i guess not. if you switched the irs for a sra would that save some weight on the cobra? just out of curiosity. huh thats really impressive for a full interior car but something tells me he doesnt drive that thing on the street nor do i think he could very easily.

They have set alot of records with the gt 500.

theres a guy in my town that has a termie with a single turbo, he makes roughly 800-900hp, and his car goes nines i believe, and his valve covers havent ever been off the car.

the one with full interior ran in the 9s wich is still good. the one that ran 7s is 3400lbs but the fact that it has a stock long block is inpressive.

9.93 @ 142 on a stock 04 Cobra longblock here

6 speed, KB2.8H, 3.55 gears, 26" slicks. Race weight around 3550.

Looking to swap to a 28" slick and 3.90 gears in search of consistant 1.3 60 FTs (best has been a 1.43) which will hopefully get me in the 9.7 range. I plan on removing quite a bit of weight and adding more power very soon (hopefully about 70-80 rwhp) and possibly a 100-175 shot in an attempt to run an 8 with the stock longblock and 6 speed.

if it cant be done with the stock Iron block, I'll be building a new motor with a teksid aluminum block (-75lbs), and will put the stock heads and cams back on it to tray for 8s with stock heads and cams.

Thats BADASS03SVT. His cars is set up RIGHT! He has A LOT of weight pulled out of it. I think his race weight was around 3300lbs. Couple that with the stalled auto and a perfectly dialed in suspension, and you end up with a car that get phenomianl ET's for the power.

Just switching to a solid axle on an 03/04 is good for an 80 lb loss.

its also got an AFTERMARKET aluminum motor

CammedMysticCobra · November 20th, 2009, 03:39 AM

Its called power to weight ratio. Getting the power to run 10s is easy its putting it down to the floor without breaking IRS and thats the hard part. Now you can always slap on $200 live rear axle and loose some weight and your good to go with some Mickeys.
