1350 deg. all day long on a "600" series 5.9,i wouldn't run that hot on a 12 valve.

 

Eh, after riding in my Brother's hopped up 2nd Gen, my brick isn't that much fun.

But I have plans for her...


I am in no way saying you are wrong either, I hope it didn't come across that way, but I think there are better options that messing with the pump right away.

 

haha i bet, start adding some more fuel and air and you won't be saying that.

I think the reason why "tweek your pump" is one of the first recommendations made to members looking to make more power is because it is FREE!! and there is nothing wrong with it as long as you use your head.

 

I would recommend that you determine if you actually have the slow spooling turbo first, my 92 has the 18cm not the dreaded 21cm. Here is a link to determine which turbo you have, climb into the engine bay and look at the number on back of the exaust housing.

I doubt an auto (non lockup at least) 1st gen will ever be as fun as a 600+ rwhp, 5spd, 2nd Gen. I do get more looks, but his is a total sleeper, so no one knows whats under the hood.

 

i bet BC847's twin turbo 518 is pretty fun to drive in

 

No doubt about that! Do you have any idea how his tranny is holding up to that?

 

don't know but i guess no news is good news.

 

it takes a lot less HP in a 1st gen to make it feel as fast as a 2nd gen.

i would say for the oridganal poster find an hx35 turbo off a 2nd gen that will get you a 12cm exhaust housing and a better compressor housing since it has a map width enhancement slot. and sounds good nice whistle

 

No offense dude, but tweakin the pump is free. Injectors are far from free. By the time you buy one set of injectors you could have bought 15+ shutoff solenoids. IF they go. The reason people say tweak the pump before hand is to get a taste of whats in store. Nobody I know that has their pump 1 turn off runaway has problems with their solenoids.

Another thing, why would you want to run 6x18s on a stock pump, when 5x12s would make just as much power with the pump turned up a bit with much better atomization.

And another point on top of that. A stock turbo can barely keep stock intercooled injectors at a good egt for towing. Why spend money to make it hotter when you should really be spending money on fuel supply and a better turbo/intake/exhaust.

Not tryin to start a pissin match, but would like to put a vote on the tweak the pump side of the argument.

 

It's not an arguement, Its a debate

I'm curious as to know what you mean by that? Intercooled stock turbos are bigger then NON i/c's and intercooled injectors are smaller so I'd imagine, oh and they have intercoolers so I'd imagine towing with an I/C truck with a few tweaks would be easier then a NON i/c truck.

Maybe I did'nt understand what you meant?

I Agree 100%, the turbo itself is an upgrade from stock, I've never driven (or riden in ) a 91.5 or 92 21cm truck but I'd imagine its bad.

 

I never told him the 1st thing he should do is get bigger injectors. I told him he needs gauges, then an exhaust. I was simply suggest an alternative that won't sacrifice the life of the VE nearly as much.

As far as why you would run 6X.018's on a stock pump. So you can make more power without having to sacrifice the life of the pump. There is no way anyone can deny that tuning up the pump will decrease the life of it. It's common sense. More pressure, and more stress equals blown up sooner.

I know plenty of people with I/C trucks that turn their pumps up, and two or three days later, they have to open the hood to kill it. Some will last longer than others, but the simple fact is, with the tiny stock I/C injectors they will fail sooner or later.

For what it's worth, Philip has a set of 6X.018's on his stock pump, and can tow fine without smoking all the time, and getting ridiculously hot. He also has an HX40 though, I believe. 1st Gens like 6 hole injectors a lot better than 5 hole.

I'm giving the advice Brian Block gave me. You don't need to turn the pump up to make power. Sure a few turns might help a little, but like Brian suggested, if you want to keep it healthy, and last as long as it should, go easy on the fuel screw. If you want to keep the solenoid, don't touch the fuel screw until you have injectors that will actually flow some fuel.

 

Alot of injectors out there are based on inj pumps at stock setting. The coaltrain injectors ill be getting come in 80 or 140hp with NO pump mods So if those numbers dont satisfy you then i guess you can tweek the pump but as for me 140 would be plenty

 

Ya, thats what i meant... A little vague reading after. But you got what I was trying to say.


Although I dont have lots of dyno time comparing equally flowing 5 and 6 hole injectors, I cant see it being that far off. Although I would think that the 6 hole injectors atomize better. But if you carry on that kind of thinking you would think 7 and 8 holers would be better, BUT...

Also, wasnt saying that shutoff solenoids dont go. I was saying that they dont go as much as you make it out. 1-2 turns on the power screw probably WONT do it. If your injection pump packs it in because the full power screw, it was probably on the fringe of going anyways. Maybe because of that, or maybe, just maybe the sad fuel delivery that these trucks come with stock. Could be lots of things for that matter.

Anyways, im starting to feel like a putz for highjacking this thread... Maybe If we want to continue debating this we should start a new thread with a poll...


Sorry OP.
