Whatever happened to the Q45 supercharger kit that BAD was working on? Does anyone have any info on it?

I am eagerly awaiting more power. My right foot is never satisfied.

My best time so far with G-tech has been 0-60 in 6.1 sec and the 1/4 in 14.2 at 98 mph. I had a lot of wheel spin. I know I can get in to the high 5's if I could hook-up better.

With the supercharger, the Q should be in the low 5's easily.

My mods so far:-modified stock air intake-Level Ten transmission-ProTorque converter-4.08 rear diff-custom exhaust w/ Magnaflow mufflers-Skyline front brake kit-Eibach springs/ Tokico struts-Stillen adjustable rear upper arm

I thought about the Jim Wolf ECU upgrade, but since the BAD supercharger is supposed to come with its own ECU, I figured why spend the money twice.

Anyway, if anyone has any info on the supercharger kit, please share it with us. Thanks.

Which model year do you have?

Keep in mind aftermarket companies have to recoup their development costs by selling a lot of kits. There's a very, very small market for the Q45.

I have a 94. When I first got it back in 98, I was disappointed in the performance. I had been used to driving a 90 Q, which some of you know has the best performance of the bunch.

Now, I can say that my 94 is way faster than the stock 90 I used to drive. But alas, I am not content with 14 sec. quarter miles and I am always thinking about what to do to the car next.

I do all the work myself. I was a mechanic in the Army and also studied Automotive Tech at Lincoln Technical Institute. Even though I never went to work in the auto repair industry, I have saved thousands of $$ working on my own vehicles. I am my own service tech.

Anyway, I just want to know if you guys have heard anything about the kit that B.A.D. was working on. I am ready to buy it when it comes out. But when is "when"?

That has been the million dollar question for some time. I choose to believe that the people at B.A.D. have been very busy. How busy, I don't know.

I'm not ready to buy one just yet. I need to get the car back to factory specs.

Hopefully the people who are ready and able to buy the kit, will soon be able to do that.

On the old website, SD gave some computed horsepower ratings based on the stage you purchased e.g., Stage I 300 - 450 bhp, Stage II 500 - 600 bhp and Stage III 650 - 800 bhp.

ARE there any SC'd Q's? I would like to see one, but I fear there never will be one.

This B.A.D. question has popped up from time to time and there really hasn't been an established release date. IMO, I dont think this B.A.D. kit will materialize, I don't see many Q45 owners, not even a handful, willing to buy this kit even if it did come out so it'd make sense if B.A.D. abandoned development on this kit.

Now as for forced induction, there have been a few Q45's turbocharged in japan where turbocharging is the weapon of choice. The max amount of boost would be around 7psi, any more than that and you're asking for trouble.

I hope B.A.D. hasn't stopped development work on the kit. From what Speeddoctor said in a previous post elsewhere, I gathered that the kit was pretty much done, but had not been put in production.

If I am mistaken, please let me know.

As far as buyers, when the performance figures are available for the supercharged Q, there will be some interested people on this site. But I could be wrong.

Now, let me ask something: How many of you are planning to keep your Q for a long time? I mean to the point that you are willing to rebuild engines and transmissions.

The other day, I checked out a new Benz S-class and came away unimpressed. The quality was not there. Most new cars are not up to the mark of the 1st gen. Q.

I have not found a car, new or used, that matches the combi-nation of luxury, performance and quality of the Q45.

sijoko - Tell us more about the mods to your stock intake.

Looks like you're getting a lot of bang for the buck - That 4.08 is ALL I WANT for Christmas!!!!

I plan on keeping my Q for a very long time. In fact, I intend to be the last owner of this great car.

I tell people that this is my '64 Mustang. The parts I put in will be worth more than the car itself, but I know she deserves it.

Ok, I'll tell you what I have done to the intake on my Q. Let me preface, by telling you that I have a Stillen intake sitting in my garage gathering dust. I had it on my car for a while. Worked great when the weather was cold.

But I live in Dallas and summer is pretty much 8 mos. out of the year. So I modified the stock intake to try to get the same or almost the same performance as the Stillen without losing power in warm weather.

I feel I have satisfied my objective.

Anyway, I'll come back and finish the rest of the post in a little bit. It's time to eat.

The first thing I did was remove the intake tubing that is under the bumper. Remove everything that is on the other side of the air box keeping only the small oval duct that connects the air box to the metal area behind the headlights. You want the engine to pull air in from outside the engine compartment.

You will notice an improvement right here and save a few pounds.

The next thing I did was to cut a hole on the bottom of the airbox and also in the metal underneath the air box. Make this hole about 3" in diameter. This will allow air to come in from the area behind the fog lights. This is where the cooler for the active cars are. I have had this mod for about a year without any problems. You could also install a PVC elbow in the hole and face it towards the front of the car for a slight ram effect.

I also use a K&N drop-in filter.

How much horsepower will you get from these mods? Maybe 2 or 3 or 5, I don't know. But, you will definately notice a difference at higher RPM's. In my IMHO, they are worthwhile enhancements.

I saw this in a japanese street racing video. Basically the guy had a T66 turbocharged first gen Q45. Both exhaust manifolds plumbed into a single turbo housing that sat where the battery is at in our cars. It was 500PS dont know how much that equates to in horsepower. It was running mild 10PSI of boost i believe. A lot of funky colors underneath and inside the car but the car ran a 12.2@115mph in the 400meters. It whooped a Toyota chaser, Nissan gloria and Supra before losing to an R34 Skyline. I can't remember which video # it was.

Check out http://www.exvitermini.com That site has a lot of cool japanese video clips like the one I saw.

hey sijoko, i did kinda the same thing you did, cutting a hole in the bottom of the airbox and through the metal. Did you block off the oval duct from the headlights or do you have two intake holes in the airbox? The cone intake made my car idle badly and stall in the summer so i removed it. A cone intake needs heat shields and ducting to work.

I recall on the old website someone had a Q45 with an airbox made for a cone intake. It used to be in the members' ride section.

Anyway, if the custom airbox can effectively shield the cone from the hot underhood temps, is it worth doing?

i have a stillen air intake system and custom routed cool air in, HOWi removed all the piping from the old, went to home depot a bought a 4' aluminum air ducting and mounted./ routed it from the front bumper under neath my lisence plate to the location where the original duct enters the engine bay just behind the driver's side headlight, still will work even better i guess if you have the stock air box with a k/n drop in.... i felt the diff when i did this change, if your in so cal area always welcome to drop by and check it out....http://www.q45racing.com

sultan, I left the oval hole open. I don't think it would hurt performance in any way.

I think that this free mod flows as well as the Stillen intake. The sound under full throttle is awesome. High rpm power is excellent.

Last winter, I put the Stillen intake back on for a couple of days, just to see if I was missing anything.

With the cone filter, the car pulled slightly better at high rpms, but was a dog down low in comparison to the modified stock intake.

i was watching mad max today and his car had a supercharger that he activated with a button while driving. before he hit it the belt on the supercharger wasn't moving, but after it was. is this possible or is it just the craziness of mad max movies?

I've never seen it, but the compressor has an electrically operated clutch that engages via one of several switches, so it is definitely possible.
