The car has an SVO blower on it. Same blower I had many years ago(not for long, but that is another story). Will(sneaky) runs this blower now. It's an old M90 Eaton. Doesn't make a lot of power, but it basically an install and forget about it blower. Very, very reliable compared to centris.
Yup, I'm running the FRPP/SVO blower on my car. And Mark is correct on this blower; it's not a big power maker (although not bad), but it is very simple and fun to drive. I daily drive my car with it, get 25+ mpg, make tons of low-end torque (fun), and then go run solid 12 second passes at the strip in full street trim. Can't ask for a whole lot more.
However, it is an M112 (the same blower on the Lightnings and Cobras), but with the integrated intake manifold.
320 rwhp for that blower with bolt-ons is about right, or maybe a little on the high side. I made 325 through the automatic, but I had PI cams (which I understand are worth at least 20 rwhp with a blower), a CAI, throttle body, exhaust, and a good tune.
My plan for later this fall is to go for the 400 rwhp with this blower in stock trim. No one has done this that I'm aware of. I think this is a very nice blower, but it's limited by the stock NPI heads/cams and the fact that it's non-intercooled. Well....I'm going to fix those things and see what she'll do....rubhands
Also, I thought about running a small shot of nitrous to cool the blower down. I ran that idea by my tuner (who is very reputable in this area), and said that he absolutely would not do that with a stock motor (pistons specifically). So I'd be a little weary of doing that.
As for what the car's worth...it's most definitely NOT worth $11,000. My car has a lot of those same mods, and is very clean, but I would never expect to get more than $5-6,000. Because that car has less miles, and may be a tad cleaner, it may be worth $6000-$7000, but absolutely no more than that. Remember, mods
decrease the value of a car, not increase. BUT, if it is exactly what you are looking for (as in, you like the body style, you like the color, you like the condition of the car, you like the appearance mods done to the car, and the performance mods are something you would do anyway), then it may be worth a little more. IF, and only if, that is the case, I might would pay up to around $8,000.
Knowing what I know now, if I had to do it all over again, right now in 2011, I'd pay a couple thousand more and get an 03-04 Mach 1. They can be had in GREAT condition for $12,000-$14,000. Add $1,000 in bolt-ons and it'll do the same thing that '98 will do, but have WAY more potential and actually hold its value. And I've never heard of anyone that doesn't like the 03-04 Mach 1 looks.
haha i know, those Frpp blowers are so rare ive barely seen any. Very hard to miss though in the pic, in my defense haha.
Haha, yes they are. One time, I had a guy come over to my car at the track after a run. I had the hood open letting it cool down. He came over and was looking under the hood. After looking at it for a minute he said (no joke), "Oh, I thought I heard a whining when you ran, and that you had a Kenne Bell.
I guess not. Anyways, car looks and runs good man!"

I didn't tell him any different. Just nodded and said, "Yea, it runs pretty good for what it is."
I have had that happen MULTIPLE times. Hence, "sneaky".
