Hey, it's been my dream to run a procharger with intercooler for a while now. I know NOTHING about superchargers, but I gotta start somewhere. Anyone have any info, price, etc? Mods are on my web site, and just so you know, I'm looking into a mid to low 10 second car. I'm thinking of looking into an 8lb kit for starters, then forge everything, then a 12 bolt, then some good sticky tires, then heads/cam. Any comments/suggestions? Thanks in advance.

 

Well, i suggest you start reading a lot of posts and then ask specific question when you confused.

I'm not even sure what specificlly your asking in your post - do you want to know what to do first?

I do know you will need a LOT more than 8# to get to the low 10's

 

I want to start out with 8# of boost, and yes, I want to know if there is any prep work I should do. I'm getting a 12 bolt afterwards. I have an automatic, and I've heard auto rears hold decently. Anything I need to buy besides the procharger kit? What EXACTLY is involved in getting a supercharger? Also, how do you guys like your superchargers? Do you regret it? Do you wish you had gone heads/cam/nitrous? Help me decide if a supercharger is in fact the right route to go. Thanks.

 

If I were to do it again, I would not put a SC on an LT1 with stock pistons. ~6lbs of boost is all that's remotely "safe", and the power gain with that much boost isn't worth it, IMHO.

You have an '01, right? AFAIK, the LS1 pistons are no better, but I am not sure of that. OTOH, the heads are better and from what I've seen, the hp gain is therefore a bit higher for the same amount of boost. Still, I would think long and hard about what my goals were. If you will be happy with the hp you get from 6lbs of boost, then it's a good idea. If not, you may as well upgrade at least the pistons right from the beginning.

I've been reading a lot of your posts, rkrause, you seem to know your stuff, so I appreciate the info. So forged pistons aren't that much, right? Maybe 600? So if I replace my pistons, and go with an 8lb intercooled kit, that'll give my car a lot more kick, right? From what I've HEARD, with my hp now, I can expect somewhere just under 500rwhp? I'll be happy with that for a while if I am correct. Let me know what you think, because I'm so psyched about getting some more hp. I have some now, just not enough to completely shut down other cars. I slowly walk on most cars now, but I just want to demolish them from start to finish. Thanks.

As far as track is concerned, I want an impressive 10 sec. # eventually. Thanks.

 

You can try this thread.
Might help a little more too.

 

Couple of ideas. First, a nice 100hp nitrous shot will net more performance increase than a 6lb blower. The disadvantages are obvious, mainly the need to refill the tank at ~$4/lb! But it's a lot cheaper (less than $1K for a system with all the bells and whistles) than a SC.

The issue with pistons isn't the cost of the pistons. It's putting them in! If you can pull the motor and reinstall it yourself, disassembling the bottom end is not difficult (or expensive if you pay someone to do it). To pay someone else to do the whole job is pretty darn expensive though. I don't want to scare you away from a SC. There are just too many people who weren't satisified with "just" 6 or so lbs of boost and ended up with a blown (up) motor. I am one of them.

i think dj:bota's post helped out..that thread has some useful topics...im new to supercharging too!

 

Of course, on the theory that "too much is just right" you could opt for my solution: both a SC and N2O.

A friend of mine has a early 90's stang. They were rated what, maybe 180-190 to the rear wheels? He installed PD S/C. They 1st time he took it out him and a buddy pulled 6lbs. They description I got was that they thought the bolts were going to break off of the seats. Hmm sounds fun to me! Any F-body should do well w/ 6lbs.

 

You should try 8# and intercooled

DarkblueTA
8# Procharger and then some

 

I dunno, but my car when it had relatively low boost (6-8lbs) wasn't all that impressive. Neither were most of the low boost centrifugal cars I have tested. The only exception was a Z06 I helped tune which gained ~175rwhp with just 7lbs of boost! Most gain in the range of 100-125rwhp with a low boost setup, and signficant gains tend to be for 3-3,500rpm up, so the SOTP gain isn't as impressive as you'd think.

When I added a good exhaust system to my low boost setup, it made a big difference - nearly 40rwhp in addition to the 105rwhp that I gained with the SC. That was quite noticible SOTP. But the 90's Mudstang that was gonna' pull the bolts out from the seat with 6psi, well, i guess it's all in your perspective.

I am not talking down blowers at all, I love mine. But just don't think that a low boost setup is gonna take you to warp 9 or something.

That's what I was thinking. 8# intercooled. I hear from a lot of people that that should be fine. Who knows, MAYBE I'll be happy with that, but PROBABLY not.

 

Rich,
I just bought the car in my sig and am looking for some "reliability" (a relative term, I know) out of it. I haven't ran on the bottle yet, and everyone on the UFBA board is tellin' me that my combo won't last one pass on the SC and bottle.

GHOSTZ recommended you as an excellent source of info. He also went on to mention an alcohol/ water injection set-up. How would that help?

Thanks in advance,
JD
