Roush roots blower installed...Pics and Driving impressions>>>

Well, all I can say is "simply badazz". At about 2400 rpms....hold on, cuz here comes the boost!!!

It fits so perfectly that it should have been an option on the 96-98 Gt's.

The install took me 20 hours and I had no clue what I was doing before I started. It was pretty easy, just time consuming. Here are some pics.

SORRY....please don't say anything about the size of the pics. I am low on time and lazy right now. I know, they are huge, just save the flames. LOL besides, what amazing detail I give...LOL

Al, here is the pic of how I hooked up that little black box, I just flipped that "S" hose 180deg. I outlined in red how it goes if you flip it around and take away the black box.:



Hey, tell me again what power pipe you have?

TIMK: Fits nice doesn't it.

1BadazzGT: always a pleasuer, lol

GarrettW: well, I couldn't remember at first since it has been years since that purchase but I now remember it is a MAC CAI. The bbk one has the BBK logo on it. I have the MAC. So there you go, at least you know the MAC CAI fits. ALSO, that little black box won't fit into the CAI hole directly like it does in the stock intake pipe.

Well congrats. The new found torque makes the car super fun to drive. I still remember installing my blower and burning the tires thru drive on my first test drive. Also the unsuspecting Ls1 that I pulled on three times from 55-120. Yes the roots sc from Roush is as lot of fun just make sure you carry a x-tra belt with you because you never know when you will shred one.

98Roush...you may want to consider not using the MAC CAI with that blower. I switched to a C&L and picked up HP. I did retain the upper part of the intake though. Put it this way...I picked up 50rwhp by getting rid of the CAI, installing shorty headers and a Borla exhaust. The CAI looks good, but I think it's robbing HP with the roots blower. The C&L filter is twice the size of the filter for the CAI.

DANMATAR...what size pulley/booost are you running?


are you saying, just replaces the bottom half that goes into the fenderwell and retain the chrom part that connects to the throttle body or the other way around?


I thought the C&L wouldn't bolt up to that beacuse it doesnt have a flange. Also, it would have to be set for 19 lb stock injectors since my svo eec corrects that.

Why would it be robbing hp?

How hard would it be to modify a roush blower to mount to a 99+ 4.6.
I saw someone had 99+ heads. I know there is no intercooler, is anyone having detonation problems?

Thanks

It really does wake up this cars. Now I ran in to another problem, my wife wants to drive it all the time.

What is the purpose of the "black box"? I didn't put it on mine.

Here comes a really stupid question, what actually is detonation and what does it sound like?

I'm seeing 9lbs of boost(9/10lb pulley)
Yes, I replaced the bottom half that goes into the fender well and retained the upper. I did have the 24lb sample tube in the C&L and I was running WAY rich. I just recently put the 19lb tube in, and I expect to pick up some HP. I'll know for sure when I revisit the dyno.

As far as WHY I was losing hP, I'm not real sure. I believe it is partly due to the bend in the CAI before the MAF. Also, I believe the filter used with the MAC system is too small for the demands of the blower.

The little black box comes on our cars in stock form. You can see it clearly in GARRETTW's picture. Sometimes, without it, you can get some intermittent humming and bouncy idle. I experienced it yesterday and it's pretty loud. I am going to modify mine to fit this weekend.

CAI is cold air intake

So when does the power taper off? I've always wanted the torque of the roots type but have heard they kind of taper off power-wise dramatically after about 4500-5000 rpm. Not like a centrifugal which pulls up to the rev limiter. I'm leaning towards the roots b/c I don't want to change my 2.73 gears.

Re: Roush roots blower installed...Pics and Driving impressions>>>

Hey...Glad to hear you solved the leaking collant problem. I was wondering if you have installed a boost or fuel pres. gauge yet...and if so ....how was that install. I know once everything is installed....that'll be my next move....Also...when do you feel the power to taper off???

RioRed.....see if you can edit that post and get those pics outta there so it loads faster. Also, I am doing gauges in the next couple weeks. I only want two gauges beacuse I don't want an A pillar triple holder because it's gonna attract too much attention from ricers at stoplights. I am going to use the autometer gauge bezel that replaces the stock one around behind the steering wheel. I will use a boost gauge and I can't decide between fuel pressure or air/fuel. I already have temp and oil press autometer in my cd player slot.

PLUS....with the fuel pressure gauge I think you have to spend another 70 dollars to upgrade to the stainless steel line. I may just stick with boost and air/fuel. The install should be easy enough. Just ground and tap I think.

To tell you the truth about the power tapering off....I haven't really brought it past 5000 rpms yet. It pulls so freaking hard up to there that I haven't been on an open enough road yet to test it out. In my honest opinion, why go past 5200 anyways with stock heads? That is the optimum shift point for us anyways.

Skip the Air/Fuel, go with the fuel pressure

Fuel pressure is more important than boost.

Air / Fuel is just something to look at (eye candy) completely worthless

If your worried about A/F ratio get a wideband done on a dyno.

I ordered mine last Thurs from Roush for 1,900.00 with everything you need....and I mean everything. The only thing is is that the kit obly comes with the fuel pump for a 98 so if you have a 96 or 97 then you can sell the one in the kit and buy one for either a 96 or 97 (has to be at least 190lph) But ya....it includes everything for that price. They have a limited quantity left. I know when I ordered mine they had about ten left at this special "blow-out" price. It arrived 4 days later ..TOTAL=1950.00 (includes shipping ($50)) website: www.roushperf.com

RioRed1997GT,

I think you have the fuel pump issue backwards. If you have a 1998 GT your fuel pump is sufficient for that blower therfore you can sell the one with the kit. The 1996 and 97 models require the upgraded fuel pump in the kit. Definately DO NOT sell it, you'll need it.

Hey 98Roush few questions for you if you don't mind.

Seeing as how the price on these kits is too good to pass up I was considering getting one for my car. I was just wondering what other modifications you have on your car to support the supercharger, my car is stock except for the air filter, x-pipe and everything back, and I'm concerned about possibly breaking something(tranny, something in the engine, clutch etc).

Second is this a truly complete kit? I mean does it come with upgraded injectors, chip. If it comes with a chip how do they handle that, you send it in they program it and send it back?

Did you need any special tools to install the kit, or where there any other hangups in your install?

Thanks for any feedback you can provide.

You need a torque wrench and a fuel line disconnect tool. Get that at ADVANCE (the plastic disc kind) and it costs $10.

Comes with a chip. If you have a 96-97, just drop the chip in, if you have a 98 you have to go to the dealer to have them reset your pats module then you can put the chip in.

You won't break anything in your car. You may want some subframes cuz the torque is amazing and if you know how to handle it and drive your car, you may experience some twist.

The ONLY thing you will need in addition is a boost and fuel pressure gauge.

I have numerous upgrades to my clutch, suspension, etc...but you don't need any of that with this blower.

WTF is "the little black box"?
The black box is a little plastic box that came stock on your idle air intake line. As far as I can tell it quiets down some noises at idle and it seems to smooth the idle out quite a bit. I was getting a wicked whine at idle as well as some surging. Putting that box back in fixed the problem.

You need to keep and install the new pump if you have a 98. 98s have a different sump design that necessitates a special pump. You can actually modify your sump to accept a normal pump, but if you just want to "drop in and go", so to speak, you will need to use the one supplied. The 96&97 cars had a standard sump, they use the same types of pumps that Mustangs have been using for over a decade. Thus, if you have a 96 or 97 you will need to just get a regular high performance pump.

That's weird, when I bought my kit the Roush guy on the phone said I would have a slightly easier install since I had a 1998 in that I wouldn't have to do the fuel pump.

Don't you mean it comes with a new ECU? At least everyone kit I've seen does! Not trying to be picky, just wanna give some acurate information.

Yeah, he misinformed you, maybe he thought you already had a high performance pump? The guys at Roush are generally pretty helpful, he was probably just thinking something else. According to Ford Spec Sheets, the stock pump is around 60 L/hr; the supplied pump is around 150-190L/hr.

There is no 255 l/hr pump avaliable as a direct drop in for the 1998 gt. You would have to just buy a standard pump and modify the fuel sump to accept it. The modification requires a little grinding to get things to fit, I think (I replaced my pump 3 years ago so the memory is a bit fuzzy). Houston Performance offers already modified sumps with a 255 pump for 175$ with a core (meaning you give them your old sump when you do the swap). That's a route to go if you don't feel comfortable doing the modification yourself.

Garrett,

Thanks for the reply...that clears things up alot...

So if I wanted to do the modifications to the sump myself, I would get the Walbro 255 lph in tank fuel pump (P/N GSS342)?

thanks again

the kit comes with an SVO EEC. It looks the same as your stock one. It is about the size of a paperback book.

Keep in mind that the Roush/SVO roots blower completely replaces the whole intake on your engine, so you can't use it with the Bullit intake you have listed in your sig. I learned that one last week.

Garrett,
I'd found fuel pump install instructions recently (not sure, where but I thought it was Saleen's web page) that lay out some mods to get an aftermarket fuel pump to fit. If I understood the gist, it was basically some cutting and grinding to the assembly because the pump itself is too large in diameter to fit. Is that the sump mod you're referring too, or is there more to it that I haven't discovered yet?

Yeah, that sounds about right. The sump is the cylindrical plastic holder that holds the pump and fuel level sending unit. You just have to do some grinding on it. I seem to remember having to do something with the little filter bag on the pump too, but the memory is pretty hazy.
