Does anyone know what averge times for diesel dragster's are? please let me what class. and could a diesel take a gas car of the same class?

Well, it all depends on what kind of class they are in. most diesel trucks race in the DHRA, it's kinda a blanket class if I understand correctly.
I think that this is one of the fastest:

but in general, they can run stock at about 16-18 seconds, and heavilly modded to run on big slicks and make 10-11 sec passes.

Why so slow?

Maybe because they weigh 6000 + lbs??

Well, why not but it in a lighter frame? or is the engine itself 6000+ lbs. If that's the case, why not make a lighter engine?

I meant trucks, dragsters are a lot lighter. In the video both the dragster and the truck were diesel. The dragster got a very low 9 sec.

Ok, I've read alot about diesel's, so why don't you see more of them in cars or street racers or other dagster's? sorry if I'm picking your brain...

you dont see diesels at the races because most diesel dually is $40k+
thats why you see alot of cheap CRX HFs at the races gutted
i was goofin around in my buddy's mustang gt with decent mods and a big Ford powerstroke pulled up next to me revvin. I've never seen 8 thousand pounds of truck come off the line that fast in my life. not only did this truck beat that mustang, it raped its bottom with no KY. and ive seen this mustang run 13s in the 1320 so id have to say that damn truck was running mid 12s easy

Well, i for one think that deisel dragsters would be a good idea, but hey i dont make the rules. NHRA does.

this f350 runs 11.42 in the video against what looks like an older rx7.

That was a good vid. Boy, at first glance, one wouldn't a 6000+ lb. truck could own a small sports car like that so baddly. But that's diesel for ya.

I ran across this the other day. Banks is building a diesel pro-mod. 2500 horse. Should run pretty quick.

that isnt diesel tho....if u actually read it says it runs on alcohol

Here's why those new diesel full sized trucks you see on the road are so powerful - one word - BOOST!
Turbo gas engines that run on 91 -92 octane pump gas are practically limited to around 15 psi of boost, beyond that they will detonate and destroy their internals.
Yah Yah Yah, I know somebody out there has a friend of a friend, of a friend that runs 30 psi on pump gas in their Supra, and makes 15 gazillion hp at the rear wheels, but in real life, coming from someone that owns and has built many forced induction motors, 15 psi is the limit, and even then it requires very percise fuel management, timing, and intercooling.
Roughly speaking, 15 psi of boost doubles the atmospheric pressure in the intake manifold, and makes the engine behave like it is twice as big. A 3.0L (182ci) V6 motor behaves like a 6.0L (364ci) V8.
Now here's why diesels make so much power: Diesel fuel is a light, crude distalate of petroleum, (close to kerosene) it is cheap and has less energy per-pound than gas. It does however have one great quality: It won't detonate! This mean two things:
#1 - Diesels can run very high compression, 20:1 - 30:1 without detonating!!! Pump gas cars are limited to around 11:1 High compression makes BIG torque!
#2 The Diesels you see on the full sized trucks these days are all turbo-charged (as are most big rigs). A turbo-charged pump gas car from the factory will run about 8:1 compression and 9 psi of boost max. Diesels run 22:1 compression, and 20 - 30 lbs of boost! People that own them modify them to run up to 45 lbs of Boost! That's 3 times atmospheric pressure!
Now look at that new Diesel Ford, it's got a 6.0L motor running 45 lbs of boost when heavily modified. The engine will behave like it is an 18.0 L or 1092 ci motor!
I don't care how heavy the truck is, a wimpy little 302 ci GT can't compete agains a 1092 ci big block, even if it is a Diesel!!!! You'd have to modify the GT by adding three 5.0L V8's and a 3.0L V6. A bit of an exaggeration, but you get the point.
So that's the story on modern diesels - do remember one thing: Diesels are inherently inferior motor when compared to a gas motor, if they were better, everbody would be running a diesel at the drag strip. They just happen to have certain qualities that make them very desireable for heavy trucks that need a ton of low rpm torque. Diesels opperate completely differently than gas motors, for example, no spark plugs, no throttle body, etc .... they are very different animals.
