Procharger vs turbo (6 speed)

your right.... hard decisions! Really what happend was i was completely set on procharger until just recently. I was bored and searching around to see if there were turbo kits available to retain factory a/c and other factory options. I cam accross the huron speed kit which sounded like a good kit, then I found out they are working on a new and improved kit that will be available this fall. This is what really changed my mind!

My last car was a 93 RX7 with a 9.3 compression LS6, TC76, T56, 3.55 gear. rolling into the throttle at low rpm would have the turbo starting to make boost at 2800 rpm. Anything after 3500 rpm would spool the turbo instantly. It was very hard to launch the car on the street with a 275 drag radial. Boost would come on so fast it would blow the tires off and it was hard to pedal. A slower responding turbo would have helped, or a boost controller to control boost by gear and rpm.
I've also drove a buddies C5 with a D1 making 600rwp. It had no where near the midrange torque my turbo had. The turbo was a lot more fun IMO.

Ive had twin turbos and a procharger on a 383, yes the turbos make more torque and power, but the gas pedal feels vague and laggy, with the d1 procharger the throttle is much more responsive which makes it fun to drive, engine is much more revy

That's the problem with the question. It really is personal preference.
Some will love the sound of the supercharger, some will love the instant throttle response everywhere.
Some will not.
Some will love the rush of torque with the turbos, some will love the silent power it makes. Some will not love the not so instant throttle response, some may like or prefer the slightly soggier feeling when you initially apply the throttle.
Ive had both, I currently have turbos, but went that route primarily because it's far far easier to make more power reliably.....plus I got fed up with belt problems and the noise.
Although I had the belt issues fairly well resolved at the end, so if it's a good well designed kit, that shouldnt be a major concern
Do I miss the instant throttle response ? Yes I do. Do I miss the noise ? Nope
Is my car performing better...with more to come ? Yep.

People above nailed it. Turbo vs procharger is like auto vs stick, or red vs black paint. All of them appeal to different people for different reasons.
Did you ever drive the car with the procharger? You said you already sold it, so it's a non-issue at this point since you're going to a turbo setup.
I find my car is plenty of fun on the street. I used to have 3.73 gears, which created too much torque and power in the midrange, so I went down to a 3.42 gear. So it's a little softer below 3,000 rpm, but still plenty of fun, and higher rpms are just a downshift away.

I agree with someone else though. If 11.49 is your set in stone goal, then just get a cam or heads and cam setup. No sense in adding the complexity of boost (of either type) for a goal that a cam only car can easily hit. If you are meaning that you will turn it up on the street and have a faster car then that is a different story and completely understandable.

Ironically, if I owned a C5 or C6 I would have a centri blower on it simply because I have not seen a turbo kit for one that I feel fits or works the way I would want one to. And the videos I have seen of the blower vettes make them look dirty.

Ok what are your power goals? If you want a bad *** street car that's fun to drive and is real snappy, then size your turbo and exhaust housing right. I'm building a lq4 with a th400. I will never take it to the track. And I know that. So I want something that has no lag. I'm also not really gonna be reving it up to 6k all the time with it. That being said I'm going with a single t4 t72 with a .81 or a .96 ar exhaust housing. I know that the .81 would choke above 4k ish. But would be a tire smoking monster. I'll probably end up with the .96 housing. But do your homework and learn how to read a compressor map.
