Big HP Numbers?

[1stgen]

How are some of you getting such large numbers on 1st gens? :--)

Hp

Well, more:



air



fuel



rpms



and a few not so well known tweaks that are part of the slippery slope of chasing BIG HP. Read all the stickies that are the first three or four items in this forum.

I believe i have the more air/fuel /rpms but not getting close to the numbers i have seen posted?Any ideas? I know the possibilities are unlimited,, but just thought i would throw this out there and see what everyone else has done to achieve such impressive numbers. Thanks

So you already have:

Big injectors,

Honkin Exhaust,

Honkin Air intake setup,

ported head,

ported exhaust manifold,

ported exhaust housing,

upgraded camshaft,

twin turbos,

some sort of enhanced lift pump,

upgraded(modified)injection pump,

optimized timing,

60 lb valve springs,

upgraded clutch or automatic trans,

if you've got all that and still aren't making horsepower then it sounds like you need to do some tweaking on your setup.

If you don't have all that stuff and you want big horsepower you probably need to start shopping.

If you put what you have in your signature then people will probably be able to help you better.

I don't have all that stuff so I'm only around 300 HP which is still enough to tow my boat fine.



Happy New Years,

I dont have the ported head,,/ exhaust/ twin turbos,,I do have 60hp injectors,,230hp pump,,4"exhaust , AFE intake,and all my screws turned up,,My dyno numbers were 238/575,,I wasnt that un happy but i see guys getting 350+ or- on this site and was just looking for a little exrtra without twins or porting my head. Thats all. I know you can get crazy power if you have unlimited funds,,but thats not my case. Ijust kinda thought my numbers should have been a little higher, How much do you think the automatic trans robs? What do you guys think? thanks.

Fill out a signature so we know what year your truck is and mods etc. Let me guess you have a non-intercooled truck with stock turbo and slippery 727 auto?

 

[1stgen]

Im sorry boatpuller i forgot to list my ride,,Its a 1993 /auto extended cab 4x4 i have 60hp injectors,4"exhaust, a 230hp pump Afe intake and turned my screws up adjusted my star wheel. Have a 16cm wastegated housing also,,Other than that its stock,Thanks

 

[bgilbert]

What injectors do you have? 60hp edm's? POD's? Governor spring, timing advanced, custom ground fuel cone, afc lever grind? Those are free mods. What kind of lift pump do you have? High flow banjo bolts? I'll take it that you meant a 16cm nonwastegated housing. If not then you have a hx40-16w? What boost are you seeing? That should be a start.

 

[1stgen]

I really feel the truck runs good i am getting about 35psi of boost,, the truck feels great but i just thought it would dyno better. I got my injectors from usdieselparts.com and my performance pump from them. I didnt do much with my pump dont want to void warrenty. Thanks.

I didnt do much with my pump dont want to void warrenty.

There ya go. We are our own warranty station... aka we have no warranty.

 

[1stgen]

I know what you mean,,But i just kinda felt my performance pump would be sufficent? It is supposed to have all the upgrades already done to it . I did turn the power screw in more and adjusted my afc star wheel along with shaving the washer. What else can i do and or find the info on it?Thanks bgilbert.

Yeah sufficent enough to pull your camper, boat, load of dirt etc :-laf . I doubt they'd install a 3200rpm gov spring, grind off the afc lever, and cut down the eccentric fuel cone. 230hp pump :-laf ?? Whats that, they turn in the fuel screw a couple turns, then clamp the lock collar on the fuel screw:-laf ?? No 230hp VE pumps in any book I've ever read. I'd also be weiry of +60hp injectors not knowing what they are, honed, edm'd, POD's, 185's, 190's. . etc...



Anyways, if you want big power, you're gonna need more FUEL and AIR. You didn't say what turbo you have, lift pump, banjo's??

First off, if you want to post good numbers on a dyno you will need to do something about the trans. The stock converter is too loose to even start to transfer the power and the more you put to it the worse it gets. Either get a good TC or convert to a lockup system. You will probably gain about 20% on your numbers.



HP is a function of rpm. If you cannot spin the motor to around 3400 rpm's you will not get the big numbers. What rpm's are you seeing now and what do the dyno sheets show for peak HP and where the curve drops?



A good rule of thumb for gauging HP by boost is 10 HP per lb of boost. Given enough fuel you can gauge where you are or where you want to go by your max boost numbers. Understand that will be effected by loss thru the drive train so it is not exact for rwhp.



If you got a warranty with your pump rebuild you got a basically stock pump with a few tweaks. I know of no builders that will warranty an all out performance pump that will get you into the higher numbers. They have build specs that Bosch publishes for certain power ranges and they adhere to them for business reasons. As was previously mentioned there are a lot of things hat can be done to increase fuel flow, but, without going into the pump and stepping way outside build specs you will be unable to get the flow that is needed. A pump flowing 100 cc's s roughly capable of 200 HP. It takes about 300 cc's to get 500 hp given the air is available.



Air flow in and air flow out also contributes. Just throwing a big filter and 4" exhaust at it will not make HP nor will it neccessarily make the gains with more fuel. There is no one configuration or setup for HP. The power can be made from different areas doing different things. It all depends on how you want to approach it and how much work you want to do to achieve it.

400/965

400/965 but dont need it anymore i may sell it



buts it has a 97 storm block 7100 stuff in it



thats why iam not on much



dont use the truck for whats its needed for

I suspect that you are loosing what you have with the torque convertor. I'm running the same numbers you are and the only performance item I have is some Bosch 185's, fuel screw turned in two turns past the lock collare and thats really all. You're making 5-6psi more boost then I am too.

Your boost sounds good for a 16 housing and your elevation.

1. Get a tighter converter so you can use and feel the power your making.

2. Get a QUALITY ground fuel pin.

3. I run an HTB2 turbo which really woke up the mid-range and top end power. I think this is a very good turbo.

4. Snow Performance water/meth systems work as advertised.

5. Some make bigger injectors yet, but what you have (POD's) works well.



With numbers 1,2 & 3 you would probably pick up at least 80 hp.

Add 4 & 5; maybe another 80 hp.

I was in the same boat too once... ... ... ... ..... maybe I still am?

On edit; I intentionally left out the "KTA special". You have a little ways to go before you ready for that.

 

[1stgen]

Thanks for the replies guys its nice to talk with other guys about this stuff, I ll probably keep it the way it is , I know what your saying(Bgilbert) about the pump,,it does have the 3200 springs and is listed on there website as a 230hp pump, the injectors are done by them also, i know thats how its advertised but doesnt really mean thats what it is, Check out there website(usdieselparts.com) Thanks for the info . Ihave been told that my trans is killing my power. Thanks again.

 

[1stgen]

glhs,,AAhhh Someone who knows where im coming from. Where can i get the fuel pin and what convertor do you guys reccomend?I do alot of diesel work for a living but am having a hard time finding parts and info on my baby. So any help appreciated.

 

[glhs]

Fuel pin;

1. Member "Old Smokey" (Mike). He works at Dyno-mite Diesel performance.

2. PDR

3. Bullydog



Torque converter; Can't help too much with that. I like sticks.

The only one I'd recommend for a first gen is a DTT.

Kurt

 

[MMiller]

I'd talk with Greenleaf about the fuel pin. A dremel and a few minutes and you have a custom fuel pin. Freebee.



I agree with PDR, one of the few shops that know anything about a first gen.



I've heard lots of good stuff from Goerend Brothers about good convertors. Dave will talk with you and build what you need. Talk to ATS, DTT, and Goerend Broths and decide. My money will go to Dave, but then again, he is just a couple hours from my house.
