12V/4R100 IN F250 DRAG RACE QUESTIONS

ALRIGHT LETS SAY I GET A TOP OF THE LINE BD RACE 4R100 THEN GO WITH A 12V CUMMINS(I CAN GET A STOCK ONE WITH 150,000 MILES ONIT. WHAT DO I NEED TO DO TO IT TO GET IT ROLLIN FAST? LIKE 11S FAST IN A 7200 POUND 4X4. I JUST CANT DEAL WITH MY TRUCK ONLY RUNNIN IN THE 14S I THINK ILL KEEP MY TRUCK THE WAY IT IS AND BUILD A RACE TRUCK THAT IS JUST LIKE MINE SEPT NO MOTOR OR TRANNY. MY QUESTION IS SINCE IVE NEVER MESSED WITH 12V'S IVE JUST HEARD THEY ARE A LOT CHEAPER TO MAKE A LOT OF HP. LET ME KNOW IF SOME OF YOU GUYS DONE IT.

ahh caps!!!! its so hard to read! screw the BD tranny and go with a BTS. ship said 12v motor with a big pile of money to scheids diesel and send the chassis out to get a cage built.

Your sig says your out of money, you should not be thinking of doing this.

It doens't matter what brand of diesel you have, its going to cost a lot of money to run 11's

I told you you wouldn't get answers if you didn't work on your typing...

dang it i forgot about the all caps stuff, alright so is it not any cheaper to build a 12v cummins to 800hp than it is to build a 7.3 to 800hp? i mean a lot cheaper not just a little cheaper. im also not agianst using nitrous to get there i just thought it was a lot cheaper to build a cummins than a ford. mabey a 500hp cummins with a lot of spray as long as the 12v can handle it. as far as out of money im talkin out of money right now. i can always get another job or sell stuff to get what i want it just seems like if i keep spending all this money on the 7.3 i wont get anywhere i want to be unless i was a millionare!

This is alot of work... but obviously you're not paying attention... This is the way your posts SHOULD look. But they should ALSO make a little bit of sense...
I tried the best I could...:doh:

Alright, let's say I get a top of the line BD Race 4R100, and then go with a 12 valve Cummings (I can get a stock one with 150,000 miles on it).

What do I need to do to it to get it rolling fast?? Like, 11's fast, in a 7200 pound 4x4. I just can't deal with my truck only running in the 14's.

I think I'll just keep my truck the way it is and build a race truck that is just like mine, except a DIFFERENT motor and a built trans.

My question is...
Since I've never messed with 12 valves, I just heard they are a lot cheaper to make a lot of hp.

Will some of you guys that have done it let me know how, and what was involved?

Don't do a cummings swap to get 500hp...
Don't do a cummings swap at all....

Alright there whats with the all caps on some words and some words not all caps?

That's me YELLING!!

Hahah i see know. i would build my 7.3 to 500hp but then i couldnt very well spray it with a lot of nitrous on top of the 500 without payin big money for billit rods mainstuds/girtel way better heads with different valve springs filling the block,head studs new expensive sticks and a big turbo. i could easly put 10 or 15,000 into this 7.3 to make it stout enough to handle all that power and even then i dont know if i could say it wont come apart. That is why i woundered about the cummins 12v and what it could handle. Thanks for explaining the typing though!

Just buy a Dodge... much cheaper in the long run...

I realy cant stand them that why i wouldnt build one. I have to look at it everytime i get in it so im not gonna drive it. I love the way the f250s look and feel on the inside just want to be able to run 11s in one and i just dont see it happinen with a 7.3 reliably and without 15K. mabey i should just scrap the whole "drag race a deisel truck" thing and stick with the sbc's im used too. This deisel drag race thing might just be for the rich folks.

Alright there whats with the all caps on some words and some words not all caps?
Ummm, it puts more emphasis on those words.

BTW--:whs:

If you only want 500 hp, do not put in a cummins. It will cost you more to swap it out than what it will cost for the parts on a 7.3 to make 500hp. There are several PROVEN setups to get you to 500hp on a 7.3.

If you want to go into the 11 second quarter mile range, then get another job. Get TWO more jobs. It aint gonna be cheap , no matter what route you go.

Besides, if you ever drive an actual 500 hp 7.3 , I think you'll be plenty happy with that for a pretty good while.

Either route you go, you're gonna need a good transmission. (BTS)

For the 7.3, your gonna need a decent set of injectors, a good turbo, probably a fuel system, exhaust if you dont already have one, head studs, and I would recommend a studded and girdled bottome end, unless you want to be doing it over again in a year when the block cracks.

For the cummins, just to get it running, your gonna need $$$$$. Adaptors, wiring, the know how to do it, or more $$$$ to pay to have it done, a lot of downtime while swapping, and good place to do the work.
Not to mention you that s just for the stock cummins. To make it run your gonna need more of those $$$$ for goodies. Fuel upgrades, and turbo upgrades along with new exhaust, plumbing for the fuel system, and oh, did I mention $$$$$$$.??

I guess you could go common rail cummins, and save some of those $$$ on goodies, and just tune it. But then the initial cost is gonna be higher for the engien to begin with.

Call one of the several vendors on here for a price on a swap.

Alright smorris , how does the nitrous affect your 7.3? have you been using it for a while? Does a CR with tuning alone hit 500hp?I think you guys are right though on the money. I do need to just rethink this deisel drag racing and go back to gas in a light car. Its so much easier and cheaper. Hell i had a 1982 s10 with a 355 and a th350 auto in it that i built for less than 5000 dollars and with a little spray i hit 10.02 at 131. I guess thats more my price range anyways. Thanks for all the input.

Thanks for all the input. With my old motor the nitrous was a blast! But, it was a bone stock 180,000 mile motor with no head studs, no nothing. Just a set of 238 cc a codes, a modded H2E, exhaust, stock fuel system, gauges, and not much else.
It would run a mid eight second eight mile at around 81 mph on the bottle. I think thats around a 13.4 quarter mile or so. Never ran 1/4, so guess I'll never know. ---on edit-- I also had swamps gen hpop.---- oops :D

Now its a shade faster, but fuel only, on a built motor.
Still looking for more. :evil.

Heavy truck too-- 8,300 pounds at the time.
But, there are a couple of guys on here running 12 seconds or so on stock motors, with head studs only.

fuel stuff, and turbos.

from what i've heard it takes around $9k just to do the swap, counting buying the engine and adapters and all that... but then you can sell back the old engine and stuff to get a little money back...
but anyway... to get a 12v to 500hp, ALL the 12v injection pumps can support 500hp easily... so fuel system upgrade are not needed, you just need new DVs and all that crap that i have no idea about, you can get a set of marine injectors for $600-800, they're smokey but they can support 650-700hp..
the turbos on those stock 12v cummins SUCK!!! they can't support a crap's worth of hp... gonna need to upgrade that too!!! but that's pretty cheap for a cummins too!!! can get a new one for like $800.. and a used for really cheap!!
then you just gotta get a BTS trans for $4300 and you're basically set...
so the money into the engine for mods AFTER the swap is around $2000... much cheaper then the $5500 i have into my truck to get to 420hp...

Just send me a check for 25K and come get your truck, problem solved :D

Maybe post this on a DODGE forum where people know what they are talking about :ford:

Either TDR or CompetitionDiesel

Either TDR or CompetitionDiesel

yes go to compD, not TDR, i've heard too many bad things about that forum
