Roushcharger and calibration

[family man]

Okay, I've decided (finally) to go with the Roushcharger for my 05 Sport . I have a question about the recalibration process done by Roush. Will they take into consideration that I have a Bassani catted x-pipe and Roush offroad axleback, or do they reflash it for the Roushcharger on an otherwise STOCK car? Anyone that has done the Roushcharger, please chime in. I would really hate to have it custom tuned and loose the warranty.

As always, thanks for your input.

Not trying to put down the Roushcharger but for the same price you can get the 6psi Whipple unit which is supposed to put out 420hp at the wheels not just at the engine. When I called Whipple, they told me that whatever mods you have done to the car can be put into their computer and a "custom" tune can be sent to you.
I suppose that what I'm trying to say is that I haven't heard anything nice about the customer service with Roush, and their blowers are programmed one way and that's that. No special tunes are available through them.

I agree with the above, roush is charging major bucks for a very limp tune in order to offer a great warranty.
Give me a 10K warranty on my 06 st 3, get me all that can be had for the bux spent.
Than i will move on to a better program, such as a KB.

yup yup the tune flashed is for Stock set up minus the kit it comes with....
well wut i meant was designed for the induction and fuel of course...

The problem with the Roushcharger is, even though it can get 420RWHP, it is HIGHLY inefficient compared to the competion like Kenne Bell, Saleen, & Whipple. We just put a Saleen blower on my car with the Saleen's 475HP Kit which includes a 6PSI pulley, 39LB injectors, and a 98MM Air Box and it dyno'd at 410RWHP with Saleen ultra-conservative tune. With a much better tune 450RWHP is no problem @ 8PSI.

The Roushcharger is good if you wanna use it as it is and match up the blower to your Roush. BUT, if you want something more upgradable in the future.. I would suggest you look at a different blower. Since you have a Roush I would recommend you look at KB or Whipple if you are going to upgrade it in the future. You'll be alot happier with a KB or Whipple than a Roush in the future.

I myself have decided to get the Whipple H.O. kit with the 8psi pulley instead of the 10psi that come standard in the kit (I know, I know less boost, but I'll feel a little safer with the hp numbers to the engine) Even with the 8psi pulley, I have been told to expect somewhere near 450 to the wheels.
Kit prices are $4800 for the non-intercooled 425 hp, or $6000 for the intercooled H.O unit 475hp. These are rear wheels numbers not flywheel numbers.

Is this a safe and sane thing to do on the OEM Engine? am not concerned about my warranty any longer.

[06Roush_st_3]

I agree with the above as well. The Roush charger is good, and I like my Stage 3, but for the money on your sport I would go with the KB. Much more efficient, and upgradable.

Roush will only do a stock general tune and will not allow for any bolt ons. Of course if you don't care as much about the warranty then you can get a custom tune and get more HP as well plus allow for your mods.

[spindlecone]

my question is: can the 3 valve engine, as we have in the stage 3s, support even 400 RWHP, long term?

[family man]

Thanks for all the responses . I kind of figured the Roush recalibration wouldn't factor in any mods .

That's my biggest concern too.

[lkygssr]

all the things stated in response to your entry are correct, but let me put my couple of pennies in........i have a roushcharger and am very happy with the performance and REALLY happy with the knowledge that if anything goes wrong i still have the warranty on my car. going from 300 hp to 415 keeps my stang competitive, pretty much, makes it a lot of fun and easy to drive. now if someone is going to do a lot of mods to their car then obviously 4.5 psi won't do you. but if you want a strong, reliable, s/c.........nothin' wrong with the roush

Long term wise the maximum reliable RWHP the stock motor has been able to take is about 450RWHP (IMO) some people say a little more like 470RWHP BUT I rather error on the site of being conservative. No one is going to bitch too much if they get 440RWHP.... BUT they will bitch if they get 460RWHP and a big kaboom! AND the tune is VERY VERY important for these cars since they only have powered rods & pistons. In fact, some people have said up to 500RWHP but you are playing on the edge then. The stock car's fuel system needs to be upgraded anywhere near about 500RWHP.

If you don't care about the warranty I would retune your car 1st and see what you can get out of it. AND then if it is not enough then go get a KB

[06Roush_st_3]

I know of a few guys that are running 500+ RWHP (I have seen dyno sheets) here, and I have seen at least one of them race. I will let you all know when the blow up. The guy I saw race was also on drag tires, not drag radials. That can't help the motor.

Thanks for the input Mike and everyone. I just don't have the stones, or the bank account, to gamble with too much hp and worry about blowing out the bottom end. I want reliability more than anything else.

I have been looking into Whipple and KB units. Whipple offers 2 units, non-intercooled and HO (intercooled). They are rated at 415RWHP and 475RWHP respectively. KB offers theirs at 401RWHP and 445RWHP for non and intercooled. I wouldn't mind the non-intercooled unit, but I keep hearing that is not good to do either. There is then danger of not cooling the charge and that would lead to detonation. Or are the twin screw designs so effecient that you don't need a cooler?

By your opinion, both seem to be close to max levels with their intercooled units. I'm just not willing to run so close to the edge, that's just me, I'm a wuss I guess .

Get a Intercooled-KB unit and be done.. MORE HP and more reliable than non-intercooled.

You've just made up my mind. Looking at their website, $5699 + $650 for the polished unit, gotta have the bling!

Yup.. gotta have show and go!

[SCPONY]

Not meaning to hijack this thread, but I read (or heard) somewhere that Roush has a smaller pulley as well as a modified airbox available for the Roushcharger on the 2005 engines. And, this mod won't affect the warranty. Was I dreaming or is this mod out there somewhere? I have searched posts in this forum as well as checking out the Roush website and all I can find is info on the smaller pulley........

[06Roush_st_3]

I beleive this is on the Drag Pack Car. There is supposed to be a smaller pulley, Jack Roush Mentioned it to me at this years SEMA show. I have a Roush catalog and it is not in there. So far there has not been a successful install of the pulley. The power created the need for more timing losing the much of the power gained. This was from a member here.

As for a intake, I have not heard. I know that the drag pack car has a cooling box where the battery would go and the battery is in the back. The cooling box allows for ice to cool the lines that run to the intercooler.
