Forged Internals?

[BlackOut2k11]

Yeah I would def go with a whole different set up for that much power. Thats good to know that I can hold what I am looking for though. Another question I am fairly set on the kenne bell system but Hellion makes a single turbo system for my car that is pretty interesting. Any thoughts?

I personally prefer the supercharger route, especially the KB option. With the KB you will have boost right off idle with a very smooth and flat torque curve (which is good). Turbos are more progressive with power, yes they might make more up top but a KB will produce a better average through the RPM range.

I've already got PI heads and don't want to dump money into unecessary stuff. And I'm def getting the forged parts this week so I can get this going by the end of the month. Im thinking compcams for the blower cams>??? Any other suggestions?

Comp cams are good, but I would at least get your heads ported, there's a LOT more power to be had by either porting your heads or going with the trickflows

One thing to consider before you order pistons, are you going to have the blocked bored? And if so, you have to figure out if it's going to be 10 or 20 over, going 30 over isn't recommended on the 4.6's because they tend to overheat when you do that.

What do you think the best choice would be for the bore? I wanted to go as big as I can but since your saying its prone to overheating I want to be intelligent about it. Is there anyway to offset the heat?

I would personally just go 20 over, because it's the easiest decision to make without opening the motor. 10 is too shallow if there's a small gouge in a cylinder wall or something of that nature, so 20 is a good safe bet, so when you do take it apart you just send it to the machine shop, get it bored 20 over, get it line honed etc....

Thanks for the help guys. Im out for the night, but I'll be back on tomorrow to try and get some pics of my car on here. I've only been on the site for a few days so I will prob. be bothering you with some more questions. Thanks again

You'll have to bore the motor too. You'll really need to look into compression as a big factor. I would run in the 9.0-9.5 range. You'll have to really spin that KB up too. I would just buy the shortblock from a company. You'll save more IMO. CHP and MMR make good shortblocks gor what you're looking for.

You don't need trick flow heads. 500rwhp has been made with unported heads and good cams. 600rwhp has been made with ported pi's and pump gas.

Listen buy a built short block(ford racing)-buy a used set of ported pi heads =bring them to a modular engine builder .Sell your engine get a good set of cams (Bullet cams).The kb blower is a good choice but price you can get the hellion kit same price and make MORE hp.You will also have to upgrade the fuel system .Expect to spend(12000) Save up do it all at the same time.Doing it in pieces will cost more in the end ..............

I had an 04 GT that I went the KB 2.1 route with. I did a lot of research and if you want 500 plus HP you need a solid core (ie forged internals) I had about 550rwhp and never saw even the slightest problem with the block and I put almost 50k on that set up. I went the same route you did it appears, I built the motor up from the bottom and ran blower cams for about 2 months until the bank account allowed the KB. It ran fine but not a lot different from stock to be honest. But my friend had an 03 GT with just the KB and no cam or head work and my car felt a million bazzillion quadrillion times faster (I would have exaggerated more but I ran out of proposterous numbers) For what's it worth in my opinion spending all that time and effort and building a motor with out the forged internals and cams is worth it.

My car has PI heads, intake, throttle body,bassani headers, side exhaust, pullies, different cam,and predator 93 octane tune. I just recently had my rear end rebuilt with 3.73's which it had before and I also installed a stage 3 f1 racing clutch package.

Problem: I don't see ANY suspension work in your mod list. Positive displacement + 3.73s + stock suspension + non-performance tires(no clue what tires you have) = nothing but spinning.

I would work on some suspension before you go pushing over 500 to your tires. No point in power if you can't put it to the ground.

Yeah the car breaks sideways in second pretty well but I am gunna do the upgrades kind of ass backwards and get the power first. I'd rather get the hard shit out of the way and the more expensive.

 

[streetstang13]

Thanks for the info I appreciate it. Still have the car?

Right, you're doing that at your current power level.. imagine what will happen when you nearly double your current power...

Who are you asking?

 

[streetstang13]

I was asking jrmandryck with the 04gt. Yeah The car will def need some suspension upgrades and brake upgrades and I am getting drag radials when I do the KB.

 

[streetstang13]

How do I put my car as my pic next to my name on the forums???

It is called an avatar. Go into your user cp and on the left hand side you will see "change avatar" from there you can upload a pic.


Good luck with the build.

I sold it about 3 months ago when I get shipped out to Arizona. But I filled that void with an 07 GT for the time being. I've been shopping around for another 01-04 but out here finding one with under 100k is damn near impossible
