Engine/Transmission (1994 - 1998) rwhp

[Ahopper]

ok so im wondering what my rwhp us. i have a 100 plate, disabled wastegate, strait piped, 16* timing, 3kgovernor spring kit, dtt trans all billet, stare weel turned out a bit and a mystery switch. actually im getting the tranni in this week. now that i can throw more power at it i want around 350-400hp any advise on how to get that the cheepest way posible. and what is the estemate on what it is now?

your rwhp should be right around 310 to 320 and 820 to 850 ftlbs torque add laser cut delivery valve or pm me I tell you the best place to send them to and you should be right about 350 after that.

 

[Cooker]

Personally I think 310 might be a bit optimistic. A #4, which is cut deeper than a #0 (also the deepes part of a #100), yields 290HP on a 180 pump truck.

I have a buddy running that plate homemade of course and it on a 95 and dv's dynoed 320hp

I guess when talking homemade plates guessing anybody's horsepower goes out the window, and I assume the original poster's plate is homemade also. I should have realized this before hand. As I'm sure you know, even if the plate is cut 1mm deeper it can make a significant impact on HP.

problem with alot of the 100 and 0 plates are not fuel curve just fuel or no fuel not the best for performance.

I don't think there is that much at the crank either.



With my mods, I'm a bit over 360 rwhp. Need a 3k GSK and to get the new turbo on when it gets here.

Well we are on this subject what would yall think my rwhp would be on my 94 w/ 256,000 mi on it. I got an 2002 hx35 w/ ported 12cm2 housing, big Greens cone filter, hx40 4in dp w/ 4in straight pipe, 370s, 181dvs, flat plate full forward, governor arm adjusted, star wheel out, 3k gsk and 15* timing. Sorry if I hijacked the thread.

I would say 350 to the ground is very close knowing what I have seen at the events I have ran or been at. The problem is heat and alot of it,something which you will have a ton of since you didn't change the charger. Your HX35/12,as are all of the HX35's,are out of map at over 40lbs of boost and create more heat than power. If you can get it spooled up early and make its power down low the numbers you want are possible. HOWEVER,if you planning on making the power late in the run and overboosting the charger out of map you will see your numbers fall off dramatically. Personally,seeing where you live at in Arizona,I would make sure the turbo was changed to lower the egts asap and then tune your existing combo. The desert heat is not a place to wire wastegates shut to build boost,run big DV's and big fueling plates,its a reciepe for a meltdown instead.

Personally I think 310 might be a bit optimistic.

Cooker. .

I'd have to say I disagree with that as we have all seen guys make more power with alot less in their trucks. I have even seen better than 330 at the tires in a 98 stick truck with nothing else done to it but a fueling plate. I do agree that with homemade fueling plates the curves are hard to determine and guess power.

problem with alot of the 100 and 0 plates are not fuel curve just fuel or no fuel not the best for performance.

KingS. .

Wouldn't that be performance?Both plates are very good for performance and have characteristics which would fit most any power hungry owners needs. Their differences are only made by the guy who did the machine work and in those style plates I have seen so many which vary in size. Those variances will make significant differences at the wheels as Cooker has already said so its easy to see no two are alike. Your description of fuel or no fuel shows me more of a delivery valve difference than a plate difference.



Dieselnasty. .

Your numbers should be the same or around what AHopper's would be. Again all that fuel and no adjustment for heat is a bad idea,but,then again its not my truck... ... Andy

Hammer, wastegate is hooked up at about 38-40 and to tell you the truth I dont see killer egts, but then again when im getting on it I have never really watched to see where the egts max at.

One thing to remeber though is that the 215 pumps in the 1998 manual transmission trucks are different animals when it come to getting HP out of only a fuel plate. The truck in question is an auto and the only real additional fueling is a plate. Unless he has done some specific P-Pump tuning I would be very surprised if the truck is much over 300.

After re-reading his post I am in agreement with his numbers not over what you quoted. I never looked back to see what he said his mods were and had missed he didn't do DV's. As for the 98 stick pumps being a different animal,well we all know better as they had the same pump from 96-98 on all stick 12vers.



DieselNasty. .

Remember,no matter how much you "port" a 12cm housing it still remains that and even a good port job will never allow it to flow the needed heat out. EGT's in short bursts are not deadly,however hang some weight on the hitch and attempt a good grade with high temps and your asking for disaster. Pay a tad more attention to the gauge and see what you really are doing at full throttle load and at speed. Remember,with the DV's you have,timing and 370's you will see heat alot faster than the other gentleman... . Andy

I was not getting at the 98 was a special pump for that model year. I was just saying that the 98 stick truck you mentioned in your previous past that did 330HP with just a plate is a very different animal than the pump in the auto truck in question. It's no secrect that 215 pumps can make HP a little easier as compared to thier smaller counterparts.

 

[Ahopper]

sorry i havnt been puttin any info in i was out of town. so now after what i have been reading it sounds like i am around the 300 hp range now my question is what is the easiest way to produce another 50 horses or more :-laf wile keeping the temps somewhat down and as cheap as possible. (i just dropped 4200 into a transmission so not much mula left :{ ) but the good side to is i dont have to worry about it anymore. btw thanks for all the input just keep it comin please

 

[Ahopper]

o yeah and you were right it is a custom ground plate

 

[Ahopper]

anyone have anymore input?

 

[JGrover]

From what i've read a 97 215hp with a #10 plate in the stock position is 360 hp and full forward is like 412 hp. The auto injectors holes are . 020 smaller then the 5 speeds. I dont know if there is a diff in the DVs between the two. Gale Banks powerpack in a 97 is 265hp/696 tq and those modest numbers, Banks still upgraded to a 14cm ex housing.

So if money is tight, I would get a 14cm wastegated housing. Can upgrade to a Stage3 hybrid 60cm compressor wheel later. Rated up to 420 hp And some Bosch 300 hp injectors (50+ Hp)or some DD stage 2 injectors(75 hp)

I was told with my setup, I would be around 400/420 hp if I put in some bosch 300s $55. 00ea

 

[Ahopper]

correct me if im wrong but i thought the 1997 auto was a 180 hp pump and if so would it be more around the 325hp range? im just guessing so someone just chime in if they know

 

[pwerwagn]

Yeah, the 97 auto is a 180 pump. Not a 215 like was being mentioned.
