my buddy is looking at a clean '89 reg. cab 3/4 ton 4x4. he wants it to run good, be real driveable, and not melt down when he is at WOT. Now i am a 24 valve guy. dont know too much about the VE pumped trucks. What should he do? and lets give it a $1000 budget.
 
For a 1000? Might be kinda hard to do. They tell me that the injection pumps limit is about 300hp. And that's running a little on the hot side
 
I don't know if you'll be able to do it on 1000 bucks, but what you need is a converter or clutch, a turbo, 1st gens like a 62/71. Then you need to max the pump out and probably get an intercooler. The stock non i/c injectors are good to 350-400. Do all that and you'll be right there. By the way the record for a VE pump is 639 hp on fuel only.
 
Low pressure piston lift pump, 60mm compressor wheel, 14 or 16 exhaust housing, and pump tuning should get it. Most stock clutches will take that much power as long as they are not abused.
 
Yeah I forgot about the lift pump, def need that too. The 60mm compressor wheel will not keep the egts cool at WOT.

It's a helluva lot better than a stock H1C is at cooling, and combined with a 16cm exhaust housing will start out a bunch cooler also. It's not the ultimate answer by means, but way better than stock and cheaper than a full aftermarket turbo. Just a used 62mm charger can blow the budget that was asked for, or close to it.
 
ok. glad the injectors are good to go. was thinkin some water injection instead of an intercooler based on ease of installation and quickness of spool. i have a 16cm housing that he can have. what has to be done to the pump? he just told me that he plans on using the truck to tow his grandpas Grand National to the track, so gotta keep it cool. hopin the water injection takes care of that. thanks.:Cheer:

the record is held by that yellow truck with the utility bed isnt it?
 
350hp isn't as easy as some would have you believe.

As far as the pump goes, you can turn up the fuel screw, add a fuel pin or cut/remove the afc lever, re-index the throttle shaft for more travel, and change the governer spring. total cost: under $20

Using a 2nd gen lift pump with the spring from a 1st gen pump will give you enough fuel supply at the correct pressure. Cheap

I highly doubt you will see 350hp on stock non-i/c injectors. They are bigger, but not that big. Get some used POD's cheap.

An HX40/16 should support that kind of HP. You really should run an i/c but if not you need a fitting to adapt it to the factory crossover pipe or just fab up a 3" crossover. Fairly cheap.

Spend the rest on a clutch. You'll need it. Do yourseld

It has been done, here's the link. 1stGen.org :: View topic - New dyno videos! Basically just copy everything in that guys sig and you got it. Plus a clutch if it's a 5-speed, or converter if it's an auto.
 
I was about to post a link to that dyno runs. That is why Piers used to say the pods are only a 30 hp injector on non/ic trucks.
 
I'm ashamed of CompD. I was expecting a build like,
"Spend $200 on a piston pump and $800 on nitrous."
 
just put down 364 hp, very usable power. got an he-351 in place of hx for a hundred bucks, plus whats in my sig.
 
The non IC injectors are pretty stout. If you up grade from them, look for some 6x .018s. You could make that power with a HX40, but a 62 S300 would be "more better". NOT having an Intercooler will only limit you towing. Racing, its no biggie.
 
forgot to mention i run a low pressure piston lift pump, important to keep the ve well supplied

You picked up 66 HP changing from HX35 to He351.... NO WAY, that 9cm exhaust housing is too small, that's a step backwards....


Glad you joined the cheap HP club. He351 was the best mod I've made so far, it improved useability and peak HP on my truck. Great mod for someone who like to tinker.
 
good to hear from you on this bb24, ive read your posts on the he. kind of funny the flak over the 9cm housing. i test my set-ups towing uphill, the He-351 cools 35 to 40+ psi boost far better than an hx. guys are slow to come around the 1st gen forums . you can read my thread on dtr 1st about spanish fork dyno day ad give your input. i can hit 50 psi with the wastegate blocked but i worry about drive pressure, should i be? what was your boost on the dyno? i had to tune my afc to spool quiker, less pre boost fuel helped. this turbo blows away the hx towing!
