Would like opinions on my new 12valve experiment
Hi guys,
I am new to this forum. My name is rob Williams. I am the co-founder and engineer for Siegrene Energy Solutions - HHO Generators and Kits. I am a 15 year ase master tech who specializes in high performance. I generally work with gas motors but have done my fair share of diesel upgrades for customers. I am going to be adding hydroxy Or h2 o2 to this truck to see if any gains in mpg are achieved. I am not expecting much mpg but do expect a great drop in particulates and overall emissions. I am open to suggestions to make better power and mpg on a 93 intercooled 12 valve with 200k. It has a getrag 5sp and is totally stock. What i have done so far: 1 turned up the ve pump 2. ported air horn ( reduced egt 65 deg) 3. added egt guage 4. servicd rear, trans, engine Plans in near future. 1. Take head off and extensivly port exhaust. 2. custom build intercooler and upgrade piping. ( I fabricate from griffin high flow) 3. rebuild getrag or transplant 4r100 or 4l80e in ( I hate chrysler autos and i already have the other 2 i rebuild autos) 4. Rebuild pump and get bigger injectors Where I need the help 1. What governer spring? I want good power but dont know what the old 12v will handle. 2. What company to get the injectors from? I want good hp and about 3o-350 and 600 ftlbs. I read alot of companys screw the injectors up. I would like affordable but also efficient. 3. Any other tricks I need to know about? Thanks alot for the help. You can follow my progress on youtube ( same user name) and I will post my progress here. Thanks Rob :pals::5: |
:hi:
Check out Dynomite Diesel Injectors they also make a 3200rpm Governor Spring. Luke |
New Era 370 injectors would be a good fit. The stock turbo will be the big bottleneck if you do everything listed in your post, but should be able to support over 300 HP.
|
Oh yea I forgot to put the turbo on the list. I have been looking at custom turbin housings and compressor wheel upgrades but am a little worried. The stock turbo feels good right now but have no clue on how long the center sections normally last. at 200k is it a safe bet to upgrade for 30 psi or just cough up 1000 for a whole turbo.
I deal with tubos alot on gas engines and 1000 dollar turbos dont last that long. i generally use turbonetics with ball bearing or ceramic bearings and they are twice as much money. Is an afermarket turbo gonna give me 200k miles trouble free service like the factory. This isnt a drag truck just something to tow with and maximize mpg and power. thanks for all the help |
Turbonetics are expnesive. Check out High Tech Turbo, they have some pretty good turbo's out there. For what you're doing, it sounds like a 62/14 might be a good combo, maybe a 64/14 or even a 64/12. But it really depends how big you go with injectors, how big a governor spring you use, your fuel pin, etc, and how its gonna be used. If you're going o tow with it a lot, I'd probably go with a 62/14. It'll give you plenty of flow, and enough air to keep you cool, but if you run bigger injectors you'll want the 64mm.
Don't bother with a ball bearing turbo, sure its nice for spoolup and power, but its literally double the cost, and for what some guys pay for a BB Single, other guys can build a decent set of twins for. And IMO, the twins will always perform better. |
i have a 64/14 and i'll tell you it is a little big to tow with IMHO. i would go with a 62/12 if i could do it over again....

Thanks for the great info so far guys. And btw anyone have a line for upgrade parts for the getrag. I will eventually fo to the automatic but have to wait for funds on a computer to control it. My getrag gets hard to shift once it gets hot so I will pull it and freshen it. So many tell me to go to a 6 or nv4500 but I have done more than enough rebuilds on both. I fully understand once I get this thing screaming I will need the auto. But I am willing to baby the getrag for a while and upgrade the engine first. I will be towing alot in the future but this engine will be transplanted to my wifes suburban first. The truck was really purchased for the engine. The truck will serve its purpose for now though.
Thanks again guys. You are saving me alot of home work. Anyone needing help on a gas hot rod give me a shout. |
There is nothing wrong with teh Getrag's... They get a bad rap. Yeah in stock form they dont shift as smooth as a NV4500 but they are just as tough with a couple easy mods.
1. Overfill it by 1 to 1.5 quarts. Jack up the right side of the truck to do this. 2. Keep teh rpms above 1800 while towing. (dont use to high a gear) 3. Use amsoil manual synchromesh tranny oil, the gears will fall into place! |
Rs thanks for the reply.
I was totally ready to pull the trans and re-synchro it today. when i pulled the drain plug the oil looker brand new. The only problem was it was 140w gear oil, I rebuild trans and knew this was a no-no. So i broke out the bore-scope and cheched out the internals. Absolutly beautiful for 180k. I had some gm synthetic gear oil for 5 speeds laying around so I put it in. ( basically full synthetic motor oil with additives for brass and plastic syncros) And wouldnt ya know this thing shifts better than any nv4500 i ever drove. Now I just have to add 1.5 qts over. :yeah: Btw This thing has no speedo cable. The previous owner scabbed it for a transplant project. I live in LA area and damned if I can find a replacement. Any one know of any good nos type stores for old dodge stuff. Also update on egt. quage is pre turbo and hottest i got today up the pass was 930 f. I guess I dialed in the pump about perfect. Now its time to delete the muffler and start adding my hydroxy and cold water vapor injection. Oh yea I am getting 17mpg city and 22 hwy empty. Is this about right? Gotta service the rear so I dont know what gears yet. its a 2wd stock dually. This forum rocks. all the comments and help are greatly appreciated. |
Hell with temps that low you still have alot of power in the pump! Get a 3200 spring, add some power with th full power screw and you can pick up some more MPG's as long as you keep your foot out of it. Also bump your timing about 1/8" and you will pick up some more milage
For comparison During a WOT run my 1500* Pyro pegs out at about 40mph :argh: If i run it out to 80 it takes 3 or 4 seconds to come back off the peg :lol: You have ALOT more room to play with that pump if you want.... its fun... But my MPG sucks because I drive like an idiot :D ---AutoMerged DoublePost--- And back to your original post... I'll answer in red...

( I fabricate from griffin high flow) A 7.3 Power Stroke with the metal ends is an AWESOME upgrade for these trucks 3. rebuild getrag or transplant 4r100 or 4l80e in ( I hate chrysler autos and i already have the other 2 i rebuild autos) guess we got that fixed already huh? :D 4. Rebuild pump and get bigger injectors Some 435's will do you awesome. I would not buy anything smaller, not enough of a jump Where I need the help 1. What governer spring? I want good power but dont know what the old 12v will handle. 3200, anything over that and your not making any power 2. What company to get the injectors from? I want good hp and about 3o-350 and 600 ftlbs. I read alot of companys screw the injectors up. I would like affordable but also efficient. New Era, they are a sponcor here 3. Any other tricks I need to know about? Do a GDS 60mm Compresser upgrade to your turbo to help those injectors. Also Bump your timing Thanks alot for the help. You can follow my progress on youtube ( same user name) and I will post my progress here. Thanks Rob :pals::5: |
rswords is telling you right on those 435's. those intercooled trucks love big injectors. powerstroke intercoolers are a great upgrade to :U:.
|
If your gonna go through all the work of porting the head, i don't think i'd drop the dough on a single charger. I think a nice set of twins will put you where you want to be. plenty of air, low egts.
If you need a powerstroke intercooler i have an extra one. |
hood stack
Have you considered a hood stack?
|
77ctd Thanks for the offer, What do ya want for it?
Overload no I dont think I would do a hood stack. 4 or 5 " out the back would be cool. Besides the black out the back is great anti-tailgating tool.:c: |
