more POWER!

Postby ahale2772 » Mon Sep 20, 2010 3:09 pm

so im looking for power and soon ill have some money and im gona pour it to the truck, im looking for 400-500 horse, (i know its alot to get it there) im not looking to tow, and im not looking to make alot of smoke, i want to be competitive pulling a sled BUT (yup theres the but) the truck has to be reliable on the street as well

id like some opinions on the following...
-Powerstoke intercooler or 2ng gen, not worried about the fit but what is less restrictive/ efficient?
-Turbo/Turbos: im thinking budget twins but i could easily be convinced of a nice single that wont get too hot and can handle a solid 450 horse, whats a good recipy for nice spooling twins?
-Timing: should i skip gears or wait till the truck really needs it
- head: stay with the 9mm non IC head or go all out and do springs, firerings ...the lot, eather way the heads coming off and getting a valve job but what is best?
-fuel- will the piston lift pump ive got handle my needs (volume+ Pressure) if i retain the front seal and run 25+ psi? will that much pressure change the internal timing much?
-injectors: budda? new era? and opinions on a nice set of efficent injectors that will match a 12mm ve? or is that where my power is limited (12mm vs 14mm)

i want to focus on packing the cylinders with oxygen, i dont want to waste fuel in the form of smoke, I dont want to enter the nitros world the only drugs im willing to use are water and meth, id rather not go to a 14mm h&r, I love the reliability of the 12mm ve and dont want to sacrifice it

i know this has all been asked before but i want to build this from the bottom up the right way, the first time
thanks in advance-Alex Hale

I have thought about how to get a big single on our trucks to spool.

What's needed is 2 things, heat and velocity. Thing is, with our timing advance, we cannot spool a big turbo well because the advancement of the injection event retains heat in the cylinders. So here is my theory.

Buy an M&H timing advance shim thingy, and RETARD the static timing on the pump. This way you build heat in the manifold to get things going. Now, LOW RPM I would believe wouldn't be too terrible but when you hit the upper RPM range, you will notice it. Now, you pull up to the sled, with timing retarded, and you bring the RPM's up. When the turbo lights (cause of retarded timing=heat and RPM's=velocity), push a button to activate the KSB in whatever way works for the Non-I/C pumps. Now you just brought back your timing and then some and off you go.

Theory everyone.

Get a 7mm head, some injectors, valve springs, 4k gov spring, fire ring. yada...

Buy a ported ringed 7mm head instead of spending the money on the 9mm. It'll pop and then you'll have a lot of money on a cracked head. It will be more initially, but it will be more dependable in the long run.

yeah i think a 7mil head will be in the budget, ive been thinking about the m&h timing thing and i think u may be on to something, i cant say i know how the ksb factors into it but it sounds logical hows about everyones opinion on sawing off the intake? ive got all the toold i need to mill it off and make provisions for a removable intake but i dont know what the gains are for my power level, i dont want to be a dyno buster but i want to get to the 450 range without cutting corners

I can't see how millin off the intake will help all that much, i would just put a twin ramhorn on it and call it good, the more hp you got the more it mite help, i think it helps if your shovin alot of drugs in it, 6 small nozzels with direct port injection. 8)

Dar- if you mill the intake, you can port the intake side of the head. Otherwise, you port the exhaust side, then have to leave the intake alone, and it has room for improvement as well.

There is more to be gained by milling off the intake then just being able to port that side of the head, it also allows for an individual runner intake which may be a bit over kill but that helps balance the incoming air so that all your cylinders are closer on EGT and lower if the manifold is built right. I am leaning towards milling mine off when I redo the head because I want usable power and need to keep my EGT's down.

I do understand that porting the intake would help some, but your still forcing air from a common sorce, such as a big tube, so as far as a 400-450 hp motor i don't think it's worth the effort, now squeez 250 hourses of nitrous in it and you've got a different story. this is my .02 but if you mill the intake off and port the crap out of it and leave everything els alone 30 hp gain my be possable buy i dought much more. but hey if it's off and you have the recorces to mill it and build some intake runners get-r-done, and dyno it so we know for sure, it would be an interesting experement. I have considered it just because it looks so dang cool.

I have never even seen pictures of a intake milled off. Does anyone have a picture to share?

yeah millling the intake is a big yes for me i like the thought of getting a nice head milling it, making a nice flowing intake, then always having room for a more agressive port, ive done a couple sets of SBC heads so i kinda have the gyst, even tho i dont suppose much carries over from N/A methods of porting, it would be easy to bring my head to school set up the prototrack and let it just slice layers off the head and have a nice machined surface as i just sit back and drink coffee, im going to start collecting parts soon this simester in school is pretty lax for me so hopefully ill get a bunch done, im going to start with the head and build it the correct way, have it ready for when i really want to rip the wotor down, i guess my last big step will be to pick the right combo of turbos and sticks

can some one give me some clear advice on the 14mm h&r?, would it make the truck not sensible to drive on thew street evey day?

There have been people that made near 450 on a stock 12mm pump. I would stay away from it, but thats just me. Unless of course KTA put the pump together. :D

Oh, is that all? :lol:

Something to consider about the turbo setup:
You'll probably run cleaner, make more power and be more streetable with twins...but if you want to sled pull with them you may get stuck in a class with trucks that the VE will have a hard time keeping up with.

haha yup thats all like most i want a swiss army knife of a truck, trying to not be unreasonable, i figure twins would give me some drivability and COOL air at the same time
