Pulling the trigger on a blower...one questions...
Well I'm probably going to buy a KB within the next month, and in doing so, I want to install in myself. I know I have the tools, knowledge, and patience to do it in my own garage. Just a few questions:
Once I install the blower, I will have it tuned immediately, but will it be drivable? The only place it's going is strait to my tuner. I know it will run like poop with larger injectors, pump, etc and no new tune.
The only other question I have is if you supercharged guys have any tips when install a roots style blower.
Thanks!

Don't run the car on a factory tune with different injectors, ect. Get a tune from a reputable tuner first.
Also, buy a Saleen instead of a KB.

Just messin' with you.... both blowers are great. Saleen has "maybe" better tuning support than KB though; there are many reputable tuners that work closely on Saleen blowers. If you're gonna get a custom tune though, you'll be happy either way.

Am in the same boat myself. Finally decided to go for a blower too. Probably won't be until Christmas though, and I'm hoping to have my tuner do the install and tune at the same time. Depends on what he wants to do it. I'm a retired ASE Master Tech so I'm pretty sure I could handle the install but to be honest, I've really shied away from most car repairs etc. for quite some time. Lazy? Too busy? Not interested in ANOTHER project? Probably all the above.

Don't confuse a roots style blower with a twin screw. They are very different. Twin screws dump the air charge right down in between the rotors. Roots blowers send the air charge around the sides of the rotors. Twin screws are much more efficient, cooler air charge temps, and much better top end power than roots. Whipple kits offer the best overall TS set up IMO. They have the largest intercooler and heat exchanger, the most efficient rotor design, GT500 fuel system, spark plugs and everything you need including a ProCal tool for a decent tune.
FWIW, the Saleen uses a Whipple compressor.

Ah yes, very true. I am interested in a twin screw. lol And yeah, I heard the Whipple is really nice too, I Just have my eye on a barely used KB kit with a whipple t/b and a custom cooling system.

Like you I bought a 700mi used KB with several extra goodies including the GT500 fuel system. If you know the kit and the owner well enough to do it, then I say definately do it. I got around $11K worth for about $6.5K. Well worth the savings. Are you getting larger injectors as part of the kit? What type of fuel system?

Good call on the KB tuner kit, that's what I have, and have been very pleased. I also already had an SCT XcalII, and found the 39lb injectors for cheap off ebay and got a new 90MM Lightnting MAF for cheap as well, so ended up saving enough going with the tuner kit to buy the polished unit instead of black. Gets lots of "wows" when I open the hood.
A good tuner should give you a "generic tune" that will get you to the shop, mine did. Even though that tune was for an identical car with the same mods, it was still lean up top and I could hear pinging. So please don't get on it until you can get the custome tune installed. My car has never liked any "generic" or "canned" tunes, always too rich or too lean. Finicky B1t@#.
I've installed two of these now, and I'm pretty much just an average shadetree mechanic. Both came out great, but the kit has some to be desired. Have a dremel standing by, as there will be some "clearancing" (read: grinding of parts) required to get everything to fit just right. Watch the bolts that screw in the new alternator bracket. One of the holes wasn't threaded well (had to buy a tap) and one of the screws was too short (almost stripped the threads) but a longer screw fixed that easy. The bracket for the intercooler pump has something to be desired, too long and puts the pump almost in the radiator.
When you pull the radiator hose from under the intake, prepair for a flood. Not sure how they fit 5 gallons of coolant (OK, I exagerate) in the crossover tube, but it's a lot!
When the instruction say pull the vent plug from the top of the coolant crossover tube and start the car, DON'T DO IT! Or you will be rewarded with a Prestone Golden Geyser that will cover your efforts with a shower of radiator fluid and distilled water, maybe a little water wetter for the heck of it. Ask me how I know.
Might as well get some HT0 plugs with antiseize while you're in there, if you don't have them already. Some dielectric grease for the injectors is also good, and spray silicone is a necessity for sliding all the hoses together. Be very careful when removing the heater hoses behind the intake on the firewall, because if you crack the heater core, as the directions say, "it will make you cry".
Anyway, that's more info than you asked for. Have fun, I know I did. And the fruits of your labor will be a great sense of accomplishment!!! Followed by more supporting mods such as better clutch, bigger tires, might as well get bigger rims, lighter driveshaft, boost gauge, etc.....

Great advice man, I will definitely be getting a boost gauge, wideband, etc... as well as more suspension, and a lighter driveshaft right off the bat.
