    Stock shortblock and superchargers

    thats a tough question and there is no definitive answer. I ran a '98 cobra with a stock pulley s-trim and a 4" powerpipe for about 20K daily driven miles, over 3 years. I saw about 9psi, maybe 10 on a really cold night. Car made about 450/380 SAE. Two weeks before I sold it, I had a...

    thinkin about sellin the cobra for a corvette

    I'm not going to tell you whats right or wrong on brand choices, but I will tell you, if you're seriously considering a used C5, go with at least an 01 model. They made several running changes in 01, especially with the block and motor. All 01 and later C5s, thanks to the release of the Z06 in...

    do bullits react better to modifications ?

    my DHG Bullitt reacted very well to mods (well, a single mod). Slapped on 275/40 nitto 555Rs and ran 13.33 :D

    Motor Trend says we lose to the vetee...just a little

    why in the world would you show up with a full tank? I feel like I'm giving away et showing up with a 1/3 tank. I usually like to hit the gate with reserve tank light flashing. :D

    5.4

    I drove a 98 GT with a navigator 5.4 dohc back in 2000. The guys name was Van Bracken from Houston. He had grenaded his 4.6sohc spraying it. He used a cobra r hood from ford motorsport and fabbed up some sheet metal intake. The car pulled pretty damn good all motor, and it even had 3.27...

    New 1/4 mile times.. Confused on some

    I already explained what happened. If you want to really learn how to analyze timeslips, you have to look at all the incremental splits. It's very obvious the last slip had a malfunction at the 1320' et, or you read it wrong. Take all the 1000 ft splits and subtract from the 1/4 split. The...

    New 1/4 mile times.. Confused on some

    the last slip probably has the corrct 60ft time, but the 1/4 time has to be off. Compare the 1/8 et, 1000 ft et with the other slips. I'd say you ran more like 13.44, not 13.04 as far as the mph, that will happen occasionally on a run where you spin off the line and 60ft poorly.

    Why do Cobras get low MPG?

    the Z06 has a .56 6th gear. The standard C5 and Fbods have a .50 I believe. I got around 29mpg on the freeway bonestock, a/f around 11.9/1. After a .591 lift cam and getting it tuned to a 13/1 a/F, I am getting 34mpg cruising 68, no a/c. Thats with a stock 3.42 rear. With the 3.90s...

    Make me smoke LS1s

    stfu I said 4.88s were "ridiculous" and thats how this whole thing mushroomed because cosby tried his hardest to convince me otherwise of that statement. He said nothing to change my mind. Reading comprehension is your friend.

    Make me smoke LS1s

    the ironic thing is, you don't have to take my word on whether 4.88 gears are acceptable or not. Even 4.56s. Just ask the 4V owners or the 4V vendors. Of the ones making a swap, they're going with 4.10s by a large margin. Next, probably 4.30s. Neck and neck in third place, 3.73s and 4.56s...

    hey red, drop that 5.0 fox off a cliff and you might finally break in the 11s :D

    Make me smoke LS1s

    besides crosby, you buying a Z06 on a sailors salary is completely out of the question. You spend hours upon hours pulling quotes and 8 month old threads on internet threads, while I'm out making money. Are you still doing this on the tax payers time? As your boss, I demand you get back to...

    Make me smoke LS1s

    you are definitely the biggest smuck running around the internet crosby. that ls1 thread just points that out. Completely unistigated, you baited me by calling me a rather bad name, and I told you exactly what I thought of it. I see you can still dish it out, but can't take it. Get over it...

    Make me smoke LS1s

    crosby, you remind me alot of the mullets running around the ls1 forums that say a 240/236 .612 lift cam "ain't that bad" on daily driving. "We can make it idle, i promise".... ya right. Maybe you can, but it's at such a level it's not very fun to drive at low speed and alot of the low end tq...

    i raced a trans am with nos

    no, I don't. Unless he was running a small 50 shot, which I highly doubt. Most will hook up a 100 shot. LS1, headers, 100 shot, thats pretty close to a 120 trapping vehicle. No way a gear change alone would have helped you that much from a roll.

    Make me smoke LS1s

    ya, thats it ole red hey, why haven't you thrown a 32V in that fox yet? can't get in the 11's, might as well. Toss in some 4.88s while you're at it. Heck, I bet 5.10s would be more better!! maybe 5.35s!! I bet you could smoke bob!! :lol:

    Make me smoke LS1s

    cosby, without the T5 you would have backed off to 4.30s in a heartbeat. Why do you keep dancing around this fact? Piss-poor drivability with a 3.37 first and broken shafts on the 2-3 and 3-4 exchanges? Damn, that could have happened just as easily in a "street" race with radial tires, forget...
