That 03 Cobra did well, running 16psi. On a whipple is a waste! Both car are to be respected. 2013 Gt500 has over 70 more cubic inches to
Remember. a 13 passes Ford durability test and has a warrantee. A costly modded 03 can go boom really easy, if the tune is off or you let the combustion chamber heat get out of control, thaking a valve or piston out.
HMM, the Term. got a waiver on the durability test??? I seem to remember in Coletti's book that the motors we're blowing on the Dyno so they brought in the expensive Mahle parts for durability. Lent my copy out so I can't ck. it now. Hell, I blew 2 Term. motors, including a Ford Re-man. with 1500 miles and no abuse, Ford sweated me but covered it...... Go figure
Who Me?? Ha Ha.. I was on Term. engine # 3 when I sold the car in dead stock form. [It sure did have a great suspension set-up] Does that make them fragile??? I miss my Term. every day
Keep in mind Ford pushed the 5.8 to the limit to achieve that displacement and the 13 GT500 is "pullied" from the factory compared to the 03. I would be very reluctant to mod a 5.8 like I would a 4.6 or 5.4 and would keep it more or less stock. 1 injector leans out and the block goes in the dumpster or gets sleeved making the walls between the bores even thinner than they are.
Then again at 660 hp why would you want to mod a 5.8 GT500 engine in the first place :rockon:
Alot of modded 2013-14 GT500s are here, making 700+ RWHP. Any blown?
That 40-110 run would be one of the worst scenarios for a '13. 1-2 shift happens at 60mph and the 2-3 in the 90's so we'd either be too low in the revs by starting in 2nd at 40 or we'd waste time with 2 shifts.
No, the issues was with the OEM rods not the pistons and was resolved long before they submitted the engine for durability test.
Are you suggesting the 4.6 Terminator engines are fragile? :dw:
Termi motors suffer from poor heat rejection in the heads and pistons siezing due to to tight Piston to wall. Pistons are ok but not as good as the 13 pistons, so I am told.
A lot of rocket sciece has bee done of the Powder metal "forged" 13 rods. Seems like all the early concern was not waranted.
The spacing between bores on a 5.8 just scares me though. The 13 needs 3.73 gears for just putting around. +60 in first is too tall.
Considering the Fox platform that should have had welded factory subframes on the Termi, the 03-04 Cobra had a heck of a suspension for a 2003 Mustang.
The 03 sure could use the current Z28 brakes however. For that matter, so could the 13-14 GT.
I hope Ford adresses the braking gap between Ford and GM.
03 is crude, loud, lacks build quality, brakes kinda suck, and you can break them at 600 hp, but I'm in no hurry to sell.
A friend's '04 Terminator Vert with 2.3 Whipple, 3.73 gears, full exhaust, yadda yadda yadda... ran with me from 30mph up to maybe 120. His car dynoed at 600 rear wheel hp. Though it's in my sig, my car has JLT 127mm intake, Lund Tune, and offroad Hpipe. Suspension is springs and relocation brackets. Now the terminator did have NtO5R's on it but he said he was spinning horribly too. I know he had no time to heat them up and it was 9am and cool in Ky. We were messing around and I even took the hit first and only ended up a half car up on him (his nose at my door). Am I expecting too much by saying I was dissappointed??? LOL! Realistically, I basically only have an intake and tune and he has thousands $$$ in his terminator but I expected to pull more. We basically edged back and forth the entire run.
I'm guessing I am 660 at the rear wheels compared to his 600. I'm sure that his tires helped even if he did say he was spinning relentlessly but again they were somewhat cold (they had about a 5 mile freeway ride to warm up). Onlookers said my car was noticeably getting looser than his. I guess a win is a win even if i did cheat taking the hit lol.
I have to disagree, the 03/04 can handle way more then 600whp safely. The only problem I ha e known with the engine was the few that had the infamous "tick" problem, I had my car compression tested ect at Ford just as the warranty ended to be sure I didn't need the head replacement as some did but my car was good to go. I think the car all around is an excellent car as far as design and reliability but maybe some people have different opinions.
fast mark with the single turbo blue cobra went through many motors, and finally went back to a reman cobra engine and started to run 8's again at the track with no problems. On modularfords, there are twinscrew cobra's with 100,000 miles that still run low 10's on stock motor. My own car makes 710rwhp through a little piece of crap 4.6 that's screaming to make that 700 and its still alive after 10 years of a million combinations. My car also has the "tick". I can go on but people get the point.
Like I said though, if I was rich and had money, I would buy a 13GT500 and park it next to my 03 cobra. BUT, I would NOT sell my 03 cobra
Not sure what you meant by "poor heat rejection" in the heads I have never heard this :shrug: Perhaps you can elaborate.
Both coolant flow distribution, and total coolant flow has been increased on the heads since 03 especially with the 13. Aftermarket water pumps and a and extra coolant connection on back of 4V Cobra heads help.
"This statement got me scratching my head. The stock Cobra brakes for the street are pretty good no one complains. The early GT500 are even better and I image the 013 is better yet (it better be the rotors weigh 32 lbs ea :uh oh. Does the Z28 Chebby stop faster?"
Z28 is a stripped down tank, still a dedicated track monster, that reportedly can do +20 laps with no brake fade. As a street car with 400 hp ,Cobras and current Mustang Gt's are fine, but 03 brakes on a 600 hp car that basically accelerates as hard at 120 as it does at 60 is kinda scary. If I could afford to put money into my Cobra, it would be Brakes, 26 Spline and an RTX clutch.
(Fancy rims with Michelin's too)
"As an electro-mechanical design engineer who has been thru every nut & bolt, wiring harness, mechanical assemblies on this chassis I can tell you straight up the build quality of the Terminator is very good. The fact the stock block is good to about 600 rwhp and the T56 hold-up very well in 800 hp cars is a testament how robust the driveline is. I think your confusing the integrity of the chassis with the term quality. The SN95 is a wet noodle chassis compared to the S197. I agree it is not as refined as the GT500 but in a performance car that is not necessarily a bad thing.
