alot of good videos in here and its not common for a cam only car in the 10's but its not that hard to do with the right set up and a big enough cam a guy local here BAIN on here went 10 with his trex car

That's the thing about big cam-only cars. They have a nasty curve. Their peak HP numbers can often be misleading and leave a lot of opponents scratching their heads.

Have you guys ever seen 03 Cobra graph....

Somebody with a cam only car come prove me wrong.......

ARCTIC '00

Yes, and?

corysmach1

There curve is very nice......

ARCTIC '00

Yes it is.

The curve on the Cobras are awesome. But as far as the whole time thing goes, and to back up what Unit might be saying is, check out the 11 second club forum. There's quite a few people running 11's with stock internals.

Bolt ons, stalled, geared, tires, and some weight reduction and some of these guys are running mid 11's. That's with no power adders.

So there are a bunch of guys with cam only cars running low 11's, high 10's. And they are on this website. You just have to wander further than the street racing forum.

On **average** Cobras have to make around 75Rwhp more than fbodys from what I have seen to beat them..

A stout (aka in the hands on someone in the know) cam only setup will walk away from a pullied Cobra.

What does a pullied Cobra trap? 116-119mph or so? A stout cam only setup is in the bottom 120s.
Now you start talking cam only stalled A4s racing pullied Cobras from a 60 roll... Of course who do you think will get it? Race from a dig and see what happens. Talking M6/M6 though the fbody will walk away on average.

Thats my experience, too. Oddly enough though, that Fbody advantage seems to dissapear when the Fbody runs nitrous. Maybe from them not using it till the higher gears or whatnot, but if your 350rwhp Fbody wants to take out a 475rwhp pullied cobra you had best bring a 150 shot to the party.

That's not even a Trex cam. That's a tr230 (Still a badass cam.) which is nowhere near the specs of a Trex.

I have personally never seen a cam ls1 trap higher than 117. thats prolly more than 20 different cars......

not sure where you guys are from but thats dosen't happen around here. and pulley cobras are traping 118-122.

k1ws6ta

Are you running 12.5 on DR's? (I'm assuming that's definitely off the bottle)

unit213

You're kidding? It's really not that tough...4500 stall, a 4.10 gear, a 28" slick, front runners, some weight reduction (3200lbs), big cam, valve train stuff, all the bolt ons, a 9" rear end, some madman suspension goodies, etc.

now i might be wrong here but the numbers that the pullied eaton cobra owners post are not realistic numbers in a way. A lot of them are with iced blowers and lots of time to cool down so it looks like it makes a ton of power but after a run or two after driving in the heat of the day that 460rwhp pullied cobra is more like a 435rwhp cobra. someone correct me if im wrong.

i love those cars though.

unit213

I would definitely agree with that providing that the Cobra doesn't have an aftermarket heat exchanger. Now, there are people that discount the positive effects of a higher volume heat exchanger. I was one of them given that my background was chemical engineering. However, I was proven wrong. After back-to-back-to-back dyno pulls, I made 630rwhp on every single pull even with a heat soaked blower, which I found to be incredible. That's without ice or cool down. The argument is that a heat exchanger has a higher capacity level but it simply moves more hot coolant. I would tend to agree with that, but seeing is believing.

More importantly is that the stock Eaton is extremely inefficient when in stock trim after running it hard without a cool down. I ran 11.29 with 460rwhp. I think that's the 5th or 6th best time ever for a '03 Cobra with a non-ported Eaton. Something like that anyway. That was prepping it properly at the track...just like any racer would. I bet it would've run a 11.70 on a hot lap pass.

ive seen many m6 cammed fbodys trap over 117 i usally see 118-120 with a nice sized cam an a4 will only see about 114-116 with the same setup

So you don't see 117+mph cam only cars but you see 122 stock Eaton cars?

You saw a bunch of poorly setup cam only cars... Any decent cam only M6 should *easily* be trapping over 117mph. Even a stout stalled A4 should be trapping over that pretty easily.

Once again someone come prove me wrong........

corysmach1

Well jesus I would hope so......thats what I said all along.......
