    How come Ford can't make an all motor supercar? The GT is great car but it basically has the blown 5.4 from the Lightening. And the Viper is all motor but it needs 2 more cylinders than the LS7 to make less power.
    my friend ss cam and nos got beat by the new z06 on the highway it was moving.

    the ford gt heads are the best heads out there and you cannot buy cobra r heads,i guess you could go with the 03-04 cobra heads there the nexts best,what do think about the new cobra

    Best heads out there as far as what...from the factory? There's plenty of aftermarket heads that out flow the gt heads....go check out some AFR's.

    i know but you have to work with the best heads that you can get your hands on ,from the start the new ford gt are best out there for the mod motor cars .i know there are better heads out there for the push rods motors,but we are not talking about that.do you still have the 4.6 or do you have a stroke 5.0L these are some good dyno numbers for a all motor 4.6,with kind cams are you using VT or COMP.:beer3:

    there wouldnt be any reason to spend the money on the GT head when you can port out any of the DOHC head and get better performance. Im running Comp cams with a .020 over pistons


    thanks 00SSVERT for that highly intelligent post, wow such GREAT car knowledge.

    Another point no one has brought up is that the Cobra.. is NOT normally aspirated.. it IS running a super charger.. super charge or a turbo on an LS1 Ford drivers.. Bow down and get on you knees..

    incorrect again, the stock shortblock of a ls1 will not be able to handle the same power a Cobra engine would. Ls1's have 346 cubic inches and a Cobra has a 281cu in with a blower.

    well.. if your not a cheep ass.. and do it right.. you reinforce everything in/on the motor.. (pushrods.. crank.. heads.. timing chains.. ect.) you shouldn’t have a problem.. Besides.. there are MANY people out there who have supercharged stock LS1 blocks..... LS1 Vs. Cobra.. run them at the same PSI.. LS1 dominates..


    PS. did you engineer both of these blocks and run all the stress test on them as well?

    of course when the ls1 becomes fully built it can handle more, but so could the cobra once you put better parts in and changed clearances for more of a race engine. And there hasnt been very many stock ls1s dominating any 03-04 engine, not sure where that internet BS came from. There was a post on ls2.com of a turbo charged stock shortblock ls1 getting pulled by a bolt on 03-04 cobra.That turbo sure flows a lot more air than the Eaton on the cobra. Even with 346 cubic inch engine, it still got pulled

    WOW you are basing your opinion on ONE slow ass car. So now all mustangs run 15s like that blown 3.8 does? That is a pretty childish way to look at other cars.

    Actually, the 225-60/15, 225-55/16, 245-45/17 and 275-40/17 tires are all right around 26" tall.
    None of them are a 28" tire.
    In fact, in many cases you'd need to trim the rear wheelwell lip to even fit a 28" tire on a Mustang.

    the 245/45/r17 stock GT rim & tire is 28 inches tall, not only does the speed calculation accurate but my speedo is dead on as well. If it was 26, then my third gear wouldnt go passed 100mph.

    Dude...you are dead wrong on this.
    A 245/45-17 tire has an outside diameter of 25.7".
    M&H makes a 275/50-17 DR that's 28" tall.
    Ford hasn't put a 28" tall tire on a Mustang.

    The 26/10.5-15 he was running is the same height as a stock tire.
    I can't post links on this board since I have fewer than 10 posts, but all you have to do is go to one of the tire manufacturer websites or Summit Racing and see for yourself.

    You are 100% right. I went through enough rear tires on my turbocharged 99 GT to fill a dumpster. The stock height with 17" wheels was 25.68. I had the 245/45, 275/40 & 315/35 and they were all the same height.

    I looked over my excel spread sheet and I was wrong. I dont know why my formula for the diameter of the wheel tire/combo was taken out. I measured my 17 inch 255 tires at home and its right or a tad less than 26 inches. I dont know what the fuck I was thinking

    but back to the arguement, a cobra will redline at 7k for a mph of around 120. I dont see how it will be redlining going through the traps yet only be trapping 110. Usually the trap speed is only a bit off of the speed you go through the lights at, not 10mph off.
