Thought I wanted to save some of my existing mods, and maybe I can, but I have decided to just get where I eventually want to be now...rather then work my way up there over the next year or so.

So please...open slate for designing my 94' 12V...how do I get a honest 600hp, and still be driveable?

I could cloud the question with what my thoughts are, but I would rather let you guys spend my money.

is money a issue, or do u got a budget ur trying to match?

Some of the combo's I've seen.

Twins, 180 or 215 pump worked over, head work, studs, fire ring or orings, decent set of injectors. Timing bumped up to 23 degrees.

MrSuzuki

Money is always an issue...so maybe I should clarify. Twins would probably get me there easy, but with a price. Although if driveablity is going to be greatly hurt with a big single turbo, then I might not have a choice. You pay for what you get...and I like everyone else...I don't want to have to do things twice...so if twins are the only way, then they are. Long way of saying I really don't have a budget, but rather a goal of driving a 600+ hp rig, every day!

twins are the way to go with a 600hp daily driver and be comfortable. head work is needed, along with ditching the 330's for somthing like the DDP4's, a dual disc clutch, valet switch maybe, a 4gsk could be used, might try it with the 4in exhaust might step up to the 5in,if you need any more money spent i could sure find a way.

I've personally driven a ~550 hp 12 valve with a big single, and drivability is definately hurt. It would smoke pretty bad unless you were really easy on the go pedal, and the charger took forever to light. At 70+ mph with moisture on the highway, it would light so hard it would break the tires loose, 35's BTW. Fun, yet scary, especially the first time or when it caught me off guard.

I'd say twins for excellent driveability, the worked over pump, and so on like previously mentioned. I read in another thread that a 180 pump is capable of more fuel than a 215 pump once both are tweaked, so you may want to check into that if you plan on more power.

i hear ya, that right there is the reason for the valet switch. definatly not a good feeling when on an on ramp trying to get into traffic.

kas83

Yes indeed clutch1. I highly doubt the twins would be as drastic, but with 600hp/1200+ torque, it won't be hard at all to spin the tires, even on dry pavement.

MrSuzuki

Some clarification or specifics on what is meant about "head work" and "pump work"? Heads...? you mean O-ring it for the higher pressure, or are you referring to some porting? And "pump work" do you mean going with larger dv's or is there something they do with the pump? I believe the 94' has the 160 pump...and understand 191's will get me up there...don't know?

kas83

Headwork would be valve job, springs, port and polish, o-ring/fire ring, studs etc. As far as pump work goes, I'm only familiar with the delivery valves as a mod, but have been told that the barrels can be changed and so forth, for more fuel. Someone with more experience with the pumps will pipe up, and let ya know what's going on.

600 horses?

what im goin for.... and with some tuning can be done

Timing in the 20 plus range, but not over 25
agressive fuel plate 0, 10, or a 100.
Pump tuned and calibrated from Industrial injection or scheids
Twins or a large single ( i perfer and have twins)
Good injectors IE DDP 4's or in my case DragonFlys
Head work, at least 60 lb springs, studs and a marine gasket...

Im in the 500 range, only 100 to go....

better of sending your pump off and have it calibrated on a bench to flow more cc's they'll add dv's for you so once done you'll never have to worry about the fuel on the pump side.

TxDiesel007

Make a very valid point...

good thinkin amigo

DD clutch-$3K installed
Headwork-$1-3K depending exactly what you have done to it
Pump-At least $1K if its gonna get built for big fuel
Injectors-$800
Twins $3500-5000
or a big single with water/meth for cooling- $2500

So whats your budget look like?

CmminsBeast

What are the disadvantages of timing so high? 20-23
Also, what about the new 62/13 s/s htt turbo. I was told it was a good choice for this project, as I am looking into a 600 hp daily driver.
Curious, does anyone have a 600 daily without water/meth & hot egt's?
