While we started our boost experiences with superchargers, we've transitioned into turbos within the last 5-6 years. We wanted to make sure we had a good grasp on it before we said, "Hey guess what we're doing now..." We wanted to spend enough time fabricating, testing on the dynos, getting a few prototypes out there, etc. to understand it ourselves before we try to help others understand it.
We still do a lot with the superchargers, too. Our Challenger is still supercharged with the same engine and supercharger combo going on 8 years now...she still runs 8's and gets plenty of play time in the summer. We were contemplating switching her to turbos, but opted not to for several reasons....time, money, she can't go any faster than she already does, etc. Plus we want to see how long we can keep that engine and blower combo going! :-D
We really like playing with turbos. We have them on 2 of our daily drivers...a GMC S15(our V6 sb chevy twin turbosystem), and an 89 GMC 1500(our 750 rwhp single turbo small block chevy system)...and on our 87 GN (carbureted V8 with our single small block Chevy kit...runs 138mph in the 1/4)
Turbos are quiet, have great street manners, can sneak up on unsuspecting vettes.....if you choose the "right" turbo for your combo "lag" isn't an issue.....no parasitic loss.....can sometimes be easier to fit two smaller turbos vs. one larger supercharger....
If you go to http://www.youtube.com/sdconcepts
you can see videos of the GN and the 89 GMC 1500. If you want to see the S-15 let me know and I'll post some pics and vids....
The good thing about working on GM, Ford and Chrysler is they all have their "good" and "bad". We take it all in and apply it to everything we build. If you understand how an engine works, it doesn't matter what the badge on the grill is...
