Sounds good, looks good. Nice setup.

As for everyone that was discussing superchargers... Why is you never hear of people putting a big good supercharger on a 7? A procharger, maybe D1 for example... there is a tremendous amount of power potential with one of that size.

FC owners are poor for the most part ROFL... it was hard enough putting a kit in that was designed for the car as well I can't imagine putting in something that was not designed for it, would be a nightmare...

Good idle. Good vacuum. Oh and the FD... Anyway...

Good work!

For example here locally I know of a nice procharger with bov for sale I could pick up for $600. Aside from some fabrication to mount it and what not what is the problem? I have a t2 right now that I built last winter that is parked for winter. I am in the process of getting parts around for 400whp this spring, I nearly bought the procharger instead of the 60mm garret that I bought a couple weeks ago. Am I missing a hidden cost in putting together a nice super set up?

The supercharger itself is going to be fairly expensive when compared to a similar turbocharger, but $600 is a pretty good deal for a head unit that retails for $2,800 new, assuming it is still in good shape. The mounting is VERY critical as misalignment can cause major problems, so a professional fabricator would need to make the mounting brackets. You could probably get away with a ghetto fuel or engine management setup, but for any serious performance a standalone EMS would be required, as well as quality tuning from a professional. I'm not sure what kind of pulleys are available from ATI, but I assume that you will need to have a custom pulley made for the 13B engine.

Choosing a supercharger is a little more difficult than choosing a turbocharger due to the supercharger transmission ratio and pulley ratio issues. ATI only posts a limited amount of information on their website, so you would need to contact them for a proper compressor map to know the surge and choke lines and estimate the boost profile. For example, the D-1 is designed for an engine producing "300-500hp" prior to mounting the supercharger, so that would imply that it would surge on a 13B unless it had peripheral porting. Also, doing some math, the D-1 redlines at 65,000rpm and has a 4.44 transmission ratio giving a max drive speed of 14,600, which would give a max pulley ratio of 1.95 on a 7,500rpm rotary engine. Since most compressors of that size usually don't produce boost until about 30,000 rpm, that would mean your engine would hit 2-3 lbs of boost at an engine rpm of about 3465rpm. If a lower pulley ratio is used to keep the max boost down or to compensate for an engine with a redline higher than 7,500rpm, then it would take even more engine rpm to start making boost. Granted this is only an estimate because ATI doesn't post compressor maps on its website, but at least you get the main idea.

If you are interested in designing a supercharger system, I recommend Corky Bell's "Supercharged!" book.

I get what you are saying, for myself fabrication is not an issue and I planned on a standalone, 720/1000cc, front mount... etc. I just ended up going with the 60mm besause it was an even better deal. I have that book, very informational. I was just pointing out the fact that a supercharger setup is very possible and can produce tons of power, since some seemed to be negative about the subject.

man i miss the FC...

Build another FC man!

-Crash-

That car was simply beautiful. I could never sell something that had been in my family for 22 years. Sorry for your loss, and yes you should build another one!

R.O.D

22 years, how long have you been married?
i would've sold my wife before my FC Rofl
im just kidding

whats the next project?

LMAO!
My FC "outranks" my girlfriend by about a year, she(my FC) is refered to as my mistress.

i am just playing with the FD now, just fixing up the brakes right now, painting calipers and new rotors pads fluid all that good stuff, slowly getting it better and better...
