How much power or boost can the Roush f150 superchargersupport?

 

depends...


since we can't see thru the internet we kinda need more info (IE, i/c, non i/c, ported, non ported, built motor, stock motor, etc)...


what's the blower speed going to be?

 

yes it is I/C, it is non ported right now. But I have talked to Mike troyer about porting it. And right now on stock motor. And I know from what Mike told me over the phone, is not to go over 10lbs with a stock motor. I've done got his smaller pulley, ported plenum and a custom tune from him.

In march I am putting on Dyna LT headers an high flow cats, Magna flow X-pipe, and dual magna flow mufflers. The COP that mike sells, his efans, different gears, and maybe some blower cams stage 2 or 3.

This question about the blower is for when, I buy my built motor next fall, just trying to get some ideas. If I get the blower ported, and have a built engine. How much boost can a roush blower put out safely? I know to boost it up, I'll have to get a double cooler for the i/c.

But what I'm wondering is how much boost can that blower put out being ported and i/c? My truck is a 2007 Roush 500RC, they only made 65 of them, that I know of. So I wanna keep it with a roush blower. I know that a whipple will kick its a** in max hp. And at one time I wanted max HP, but now I wanna keep it with the roush blower.

 

there's still TOO MANY VARIABLES

up to 750 according to troyer performance
look in the supercharger section

About in the middle is where it talks about hp

 

Stock block can handle more then 10PSI of boost, however you are pushing your luck but some guys drive with 12psi just fine. A small roush blower can probably handle about 16PSI with port job before it just makes more heat then power with good cooling mods (dual heat exchangers, possibly killer chiller etc). At that point you really could be making better power with a better blower.

I would put long tubes on the truck, a good exhaust setup, Efans that are not troyer fans (Ive heard horrible things about them, although random good), keep stock coils and get the solid coil plug wire upgrade over the stock springs. I would go probably 4.10 gears if you plan to run the truck at the track, if not you can go 4.30 or even 4.56 depending on rim and tire size.

You cannot go to big with the cams on stock springs. We share the same cylinder heads as the mustang guys so we do have a wide range of cams. Problem with a stock motor is we shift at around 5-5500 RPM, most cams peak at 6500-7000 RPM. I plan to install the Detroit Rocker blower grind cams as I saw a claimed 27RWHP/16RWTQ gain with them plus they sound like a bigger cam then they are. Any bigger of a cam and you need a solid bottom end to be able to shift at higher RPMS and at that point you basically will want better heads and valves and springs then you can get the big blower cam and actually use its power range.

 

All I'm asking is how much boost will a Roush I/C ported blower make safely. Minus anything on the motor or heads. All I'm wondering is if I can get to my HP I want, or do I need to go another route on getting a different blower

rambo; you link did not work, I got to there site but it says. The script you were running encountered a setup error

Iron; i didnt see your post till after I wrote this post. Thanks for the info. i have 22" wheels with 305/40r22 tires that are 31.5" tall. I will run the truck at the strip every now and then but it is my DD. with that in mind what gears?

 

And all I'm saying is heads, cams and exhaust will lower the "boost" level while still spinning the supercharger at it's MAX rpm

 

if you are staying stock and adding the supercharger, i would stay around 10psi to be on the safe side

 

4.10 gears should be fine. I plan to do a 305/45/22 and 4.30 gears as its a 32.8" tire and possibly a 4.56 gear. I dont plan to run at the drags though as I picked up a project car and want to finish some things on my truck and then just leave it alone.

 

If you're looking to go to 14 psi or above, you're better off with a twin screw. The M112 can be safely driven to higher boost, but it's going to be generating a lot of heat even with a ported blower and it's not near as efficient as a twin screw at those higher boost levels. You're going to need an upgraded fuel system and larger injectors to take it beyond 10 psi, not to mention good rods and forged pistons.

Cams for 4.6s are not going to run in the same rpm range in a larger displacement 5.4, so count on your rpm range to be about 12-15% less if you go that route. FRPP has some nice looking CNC ported 3v heads too.

 

I'm already at 10lbs of boost, and I know I need a built short block before I go above 10lbs of boost. Thats why in a post I made earlier thats why I said "This question about the blower is for when, I buy my built motor next fall, just trying to get some ideas."

Plus I will need a built tranny, different stall converter, twin or tripple fuel pumps, different drive shaft, better cooling, larger fuel injectors, different axel shafts, and the list goes on and on. I know all this going into this. Thats why it will more than likely be a year before I buy my other short block, but in march I'm throwing another 4 grand at it. in other bolt ons.

 

The only reason I'm even thinking about keeping the roush blower is cause my truck is 1 of 65 made. And if after I'm done, and maxed out the blower. If I still have a thurst for more, then I'll pull the roush sc and put on a whipple. The roush blower came with the truck, just trying to save $6000

 

Just to give you an idea I am running a +8lb lower pulley, have long tubes and 3" mandrel bent dual exhaust and my exhaust side of the head is ported. My boost is right at 12lbs if you run the numbers with my pulleys I am pullied for 15lbs. You can see how my exhaust head port and exhaust system have lowered the effective boost number but I am still producing the power of 15lbs.

 

The link worked for me, its in the roush supercharger section at troyer performance.
