What else is there

[martinoledad]

ok im looking at what to do to my truck as far as performance. I already have
-True dual magnaflow
-K@n CAI
-Jet MAF(I know your all's opinion but i already got it)
-SCT programmer with custom tunes
-troyer underdrive pully kit

On the wish list
-longtube headers(havent found a kit yet)
-BBK 80mm Throttle body
-Suncoast ram air hood(sticking with the K@N CAI not theres)

I want to so the last three at the same time so that way I dont have to get my tunes redone more then once. I also seen this from summit racing what do you guys think (so it may be a little while)

Can you guys think of anything besides a supercharger.

[ticopowell]

a big think that I have heard of/felt is to get rid of as much mass as possible. its amazing how much 100 lbs can do to performance. i have also thought of a supercharger, and I asked a shop around here that i happened to drive by, and they said they could do a supercharger, with a custom dyno tune, for around $6000. If i had that kind of money lying around I might think about it :hehe:, but other than a supercharger, all i could really think of is to change the cam shafts, use different intake and exhaust parts, or get a turbo... :smiley_roll1:. :), im sure others have better advise, but that is what I think.

[martinoledad]

how much more HP can you get out of getting an aftermarket cam shaft.

[ticopowell]

I personally didnt know, but this web site (http://www.rpmoutlet.com/04f150cam3.htm) says that its up to 45 hp... so quite a bit in my book :D hope that helps :)

[ticopowell]

Also a new throttle body (not the stupid 1" spacer) could help get more air/fuel into the engine, its larger than the stock one so more air can enter

[martinoledad]

WOW! there is alot on that website id like to have after looking at it. Do you know if doing any of that would hurt the gas mileage.

and thanks,

[ticopowell]

I cant say for sure, theoretically any change to add power makes the engine have to work less to do regular stuff, but adds the tendency to use the right foot more.. so if you drive exactly the same as before then you will see some improvement, but if i did all that, first i would be broke :hehe:, but I would definitly use more gas. and your welcome :)

On those camshafts on the level 3 it says on one brand that it is a rough idle, and on the other one it says very very rough idle. what does it mean by rough idle and can that be fixed by custom tuning.

also on the crower brand it doesnt say it needs lower gears but on the crane brand it says lower gears required. :confused:

and what can those springs do

and as far as the cylinder heads go. it talks about the 5.4 in the description but it only talks about the 4.6 in the applications.

[ticopowell]

Honestly your guess is as good as mine for those questions, lets see who else know something about them. :)

with aftermarket cams the engines power band is moved slightly higher with each "stage", by rough they mean the engine is wanting to be higher in the RPMs but can't. for tuning its mechanical and i don't think you can smooth the idle, i may be wrong though.
also on the crower brand it doesnt say it needs lower gears but on the crane brand it says lower gears required. :confused:

all the gears do is to help get the engine into its new power band sooner
and what can those springs do
aftermarket springs have more pressure to close the valves faster to prevent valve "float" which will cause SEVERE damage if not used
and as far as the cylinder heads go. it talks about the 5.4 in the description but it only talks about the 4.6 in the applications.

both are "modular" motors, block/heads/cams/cranks, all can be interchanged

[martinoledad]

so in other words if im going to do one of those upgrades i might as well do all of them. How much extra power do you think i can get with the extra tuning. It says around 100 HP with out the tuning.

[jmt0645]

if your gonna do it, may as well be right the first time:thumbs up yellow:.
most of the HP claims assume ported heads/valves, on stock heads a more realistic number is ~70HP. also, most claims are not "peak" gains.

[88Racing]

Seriously.
The best bang for your buck would be a supercharger.

agreed, i just don't have that kind of money at the moment:smiley_roll1:

Neither do I!:)

[martinoledad]

my goal is to get as much power without losing gas mileage.

Interchangable=yes.
Component compatible=no
Certain things will need to be exchanged like intakes to make it work.

[freeman.public]

Increasing your cam duration / lift will move your torque curve up in the RPM band thus raising your HP. It will certainly reduce your mileage. High-duration cams have a longer period with the intake and exhaust valves both open. It drops cylinder pressure and wastes gas as the fuel/air mixture flows from your intake to exhaust when both valves are open. This flushes out the exhaust gases from your cylinder, resulting in more power. You will also need to ensure that the rest of your components match your cam if you change it dramatically (head ports, valve size, intake runner length, header length, injector size, computer program, gearing, torque converter slip, etc.) I would be careful about making a large change in cam design in a modern engine.

Thanks, If i understand what you are saying this isnt the way to go for what im tring to do.

can this be helped by custom tuning.

How much of a performance gain can i get with premium forged pistons like these

Keith Black/KB Pistons IC884KTD-020 - Keith Black ICON Premium Forged Piston and Ring Kits - Overview - SummitRacing.com (http://www.summitracing.com/parts/UEM-IC884KTD-020/)

Will there be a MPG lose with something like these.

Or is there a better brand, i dont know much about pistons and stuff like this

[88Racing]

If you're planning on splitting the block then go all forged internals with a supercharger. The pistons alone aren't going to help much by themselves.

Or.....
Call it good and buy yourself some of these.

Just a thought........

[kelley350x]

Would you be paying someone to install these pistons, cams or other internal parts your asking about?

[martinoledad]

Yes. If or when i decide to i would have somebody else to it. I dont have the tools or anything like that to do it myself.... Plus im afraid of breaking or messing something up.

[kelley350x]

I would decide on a performance shop that i wanted to use then ask them what they recommend.
If you take a cam and pistons to a mechanic and ask him to install them he will do just what you ask. the first time you start the truck and your valves start poping holes in your pistons the mechanic is going to say "you brought me the parts."
