i have the roush and i have dyno mumbers in my gallery did it on monday (the dyno). have a video at putfile.com type in smoken f-150. that is my truck he was talking about with the 15.8 ran a 16.4 with superchips 91 tune. that was before the tune from mike ****** and im in a 4x4 so there is a good bit of loss with a transfer case i would do it again but if i were u i would wait roush is coming out with a intercooler in the next few months was told that by some one who works at roush. on the fuel roush says 91 no more no less. had some 104 ot boost still in the tank when had it installed it killed the plugs the dealer replaced them for free. and name brand gas ONLY he said dont put any thing in the tank but gas save your money u dont need it s

 

I think you would be better off putting some money in that KFX400 so you can keep up with the YFZ's J/K

 

With the new suzuki 450, then I would like to see the yfz's keep up.

 

Good point ! No doubt the New Zuk will be tight. Just wish they built a cross county set up as well. We are definately lucky.... I remember when the sport bikes included only options like blaster, warrior, banshee, mojave and 300ex

 

Is it possible to use the Roush SC with the original air filter? I don't but I have heard that driving dusty roads with some K&N or similar air filters lets dirt in the engine.
Is it possible to change the pulley size so that the boost level can be changed?

 

Here is one that I am not sure if this could be true. A guy with (I hate to say it) an Avalache, put a whipple supercharger on to tow his boat. He said he ran 87 octane and got 3 mpg more while towing. Could this guy maybe had a custom tune done for his truck. I am not looking at building a race truck, I am more interested in towing.

 

So lets see buy a $5,000 supercharger and maybe gain a few more MPG of which I doubt, you will probably use more fuel, but you will tow better and I doubt you can use 87 octane.
I currently tow over 7,500lbs with a 5.4 3:73 LS using 87 octane, and it tows fine.

 

Got the roush s/c for 3800 friday. should be here next friday. Will post when I get it installed. If any of you have suggestions when installing it let me know.

 

Please keep us posted. Where did you get it for $3800? Great deal.

 

Got it through Amp Performance, they had it on ebay. Everything is still in the box. It should be here on friday or monday

 

Will pick truck tomorrow, 450-500 bucks to put the s/c on. Stock dyno numbers where 238. Will post with what i think.

 

Got my truck back today, Final numbers 297 hp, 326 tq. It isn't as much as I hoped but it gets up and goes really good.

 

They have the roush on EBAY for $3,948 bucks plus $120 for shipping...Hell of a deal compared to the $5,200 msrp

 

Im intrested in the Whipple, I just want to find someone that has it. Just to see how they like it. 5400 is a lot to spend. Please correct me if Im wrong, but wouldn't the Whipple be alot better that the Roush since it intercooled? Whipple claims an additional 170 RWHP! Thats awesome.

 

roush has an intercooler coming out in jan i have the roush because it has a 3yr 36000mi warranty and does not affect the ford factory warranty
