my engine should be finished and shipped to me within a couple weeks. I had plenty of machining work to be done so it's taking some extra time. Other than that I've got to finish porting my intake this weekend, finish porting my plates, finish fabbing up all my braided lines and fittings and then give it a wash and wax.

The svo blower is too small. You'll have to run a giant crank pulley and a tiny blower pulley to keep decent boost pressure up. It'll also heat the hell out of the air charge. Use at least a 112ci blower if you're using positive displacement.

Decide what you want to spend on gas each week and we'll tell you what you can do to the motor that'll do that.

 

so the svo blower is to small for the 5.4? man that sucks.

 

svo blower is only 90 cubic inches and is a conventional roots type. I'd be looking at something like a 2.2 or 2.4L KB for roots/ts type or a Vortech T trim for centrifugal.

 

so the s trim is too small also?

 

it's nearing too small. It'll handle the flow but a bigger head unit means you can use a bigger boost pulley and have some flow left. The S trim will work... I just think the T is a better option.

 

o ok, cool. I got a lot to think about.

 

I've been thinking and doing on my project for about 4 years now. It takes time but it's totally worth the effort. The more you put in the more you get out.

 

slow going but here is an updated pic. waiting on my radiator...

- and yes, i know the belt is to small.

 

looks nice dude. Hey red, one question for you. I'm looking into a cheap supercharger and i seen a thread on another forum and they were talking about this company that is makeing a kit that you could hook the 03 cobra supercharger to a 2v motor. They are designing this kit for the 4.6 but i figure they could use it on the 5.4, just added hight since it will have to adapters lol. funny stuff. cobra to 4.6 then 4.6 to 5.4 lol. anyway the cobra blower should have no trouble pushing the 5.4 should it? since it stuffs the air into a big cobra motor.

 

The SVO is both actually.

They have an M90 kit, and a M112 kit. I believe its dependent on the year the kit was designed for. There was a huge debate about that on one of the other forums.

In reguards to the guy asking if the cobra blower would push a 5.4. Its the same 1.12L blower the Lightnings use - so it should do fairly well.

 

o ok so the 03/04 cobra blower is the same as the lightning. Thats nice to know. They said they are makeing a intercooled one too. soo thats good to know. It might work.

On the flip side though, i was talking to one of my guys on corral and they said that one of their old cars had an 04 pi engine in it and put lightning maf, crower stage 2 blower cams, deleted egr, and custom tune with the svo blower running 6 psi and his car made 422 rwhp/ and 403 rwtq. That is really good for such a cheap investment. Starting to think....

 

The 03/04 Cobra, Lightning, and Harley all use an Eaton M112 Supercharger. However the Cobra has a rear inlet vs the L/HD top inlet, and they bolt up differently.

All 3 are allready intercooled stock via an air/water setup in the lower manifold.

Those arent bad #'s on that car for 6PSI and cams, but the FRPP blower isnt what I'd consider a cheap investment. The eatons also get hot quick, and run out of steam even quicker. Something to keep in mind. If that was a 5.4 2v it would probably have been 440ish/470ish on the same setup, by my guess.

 

I'm pretty surprised at the numbers they got. I'm wondering if the high HP number is representative of a high compression motor and the 6psi being reflective of a limit for pump gas at say 10:1 static compression unintercooled.

In any case, if you're going to do it use a twin screw, turbo or centri. They're more friendly to upping the boost later on especially with larger cubic inch motors.

 

This man speaks the truth.

 

Naw R3D, it was a completely stock 04 longblock, also i think the pi cars have less compression than the npi cars. 9:1 vs like 9.5:1 or so. I think that was a pretty bad *** thing, he even posted dyno sheets to prove it. It looked really good.

 

So why don't you think its a cheap investment? Is there some hidden cost to these things? And what do you mean run out of steam? do they break easier or what? That dyno graph showed it topping off at 6k and then started going down. but that was mainly the cams though i think.

I do know that they heat up very quickly and that you can't get an intercooled one, but i think it is a pretty slam up street blower, something not to serious.

 

There is the FRPP supercharger kit, then there is the FRPP supercharger installation kit - those two items together weren't cheap last I checked.

By run out of steam, I mean they hate the high RPM's and they get hot FAST, especially the ported ones.

Have him do about 5 dyno runs - I bet he'd be shocked to break 390rwhp on the 5th pull.

 

yea i don't dout that it would go down really quick, that motor is no longer together though since it bent a rod. but i still think its pretty desent, looking that the fact that the kb is like 5k. But why would the ported ones get hotter faster? just because of less material? or not?

 

Not sure why really, I could speculate, but from my experience they seem too. I've always used that against them, and often they dont ever figuire it out

I just looked at FRPP, the supercharger is $2500, and the install kit is not listed but says it is required, also does not include maf/injector/pump. Your in the Vortech price bracket, on eaton power - makes no sence to me.

 

yea, i understand. I'm just wanting a roots/twinscrew supercharger. So what is the mater with eaton power anyway?, i don't get it. I've seen them make really desent power. Plus i'm going to look for a used one or something. Maybe if i can get a deal on one. Plus i really don't want the injectors/pump/and maf since i would be going with the lightning maf, 42 pounders, and a 255 f/i pump. But ford does list the kit, for the 98 it was really exspesive but its suppose to have those things in it too, plus the "computer" which is junk. I just gotta look into it more.

 

The Eaton is 1.12 Liters vs the Old KB's that were 1.7L, and the new ones that are 2.2L and 2.6L

The Eaton is a roots, vs the KB's Twin Screw. Roots compresses air one time by forcing it into the engine. Twin screw compresses air twice, once between the rotors, then again shoving the compressed air into the engine.

Twin Screw is more efficient, and the KB's are flowing more air.

It takes more boost (read: more heat, more blower rpm's, and more heat) for an eaton to match the power a twin screw or vortech will make.

 

shouldn't be that bad for 6 or 9 psi though right? I'm not really worried about haveing the fastest car. but i would like something that is nice and looks good. So its whatever i can get for the cheapest. I might can find a deal on a svo, if so i will get it.

 

woo hoo

my 5.4 block should be here tomorrow.

I got a 98 model (built late 97) F150 block and crank, so the crank should be forged.

It was an entire shortblock but the bone yard tore it down to inspect the cyllinders, i told em just to ship the crank and block

$200

 

wow very nice

 

Yea, I have $150 freight on top of that, but it would have cost me $120 to drive down there and get it plus I would have to take off work so thats more lost cash.

 

i hear ya man.

 

Anybody know someone running xe270ah on a NA car? Got dyno numbers before and after? Just after?

Anyway, ticking off the days toward my new engine showing up... gitty with excitement.

 

W00t.

I'm taking mine to the machine shop to get cleaned up this week.

 

From another board...

 

What board?

I'll probably grab the timing cover
