I talked to a kid last week in a sweet 94 Anniversary Edition TA. He had just had a Vortech S/C installed running 7lbs (no intercooler). I asked him about what he had done to his bottom end, heads, cam, computer and exhaust! To my amazement he looked at me with this deer in headlights look and said, "nothing! Why?" Now I'm no expert on S/C but I have done some research on it and I told him about the extra pressure and force on the engine and how his heads and exhaust were bottle necking his performance, etc., etc.!!! This guy obviously had done NO research whatsoever!!!! He didn't even have a fuel pressure gauge or a boost gauge!! I think he must have seen the unit in a magazine and thought 'I think I like this. I"m gonna buy it!!" I wish him luck with his mod....he'll need it!!!!!!

 

That motor will be toast soon. Especially if he beats on it like I beat on mine!

 

That reminds me of this Prelude that runs around my school. I was working on my car once and this guy comes buy with this car, revving till it missed and then asked me if I wanted to race.
Being neck deep in taking my engine out of corse I said I would take a rain check, but I asked him what he was running, and he said "I got a blower on it!! Guy who sold it to me says it puts out 15 psi." So of corse I have him pop the hood....and yes he has on of those leaf blower electric 'superchargers' found on ebay......I just smiled and said "rad". LOL

bahahaha

 

If he tunes it and runs decent gas he will be okay.

I think alot of guys have problems with boost on stock cars becauase they try to use the stock programming with the car.

I've tuned several cars that range between 15:1 and 10:1 AFR with stock off the shelf kits.

I've got a few cars around here with over 100k miles and a few years with a blower

 

You have some magic power most others dont . Hyper slugs and high compression just dont work. Avoiding detonation with no inner cooler must be a pain.

 

The complete Vortech supercharger system is specifically designed to work on a stock engine, and stock engine components (bottom end, heads, cam, computer, etc.) without causing damage. Would improved exhaust, or an aftercooler help it? Of course, but the system is designed to work with the stock programming and air flow requirements. The issues that you have raised are serious, and correct; but Vortech has systematically addressed each problem and solved it. There are components included in the kit to deal with inherent problems for each specific application. Their kit includes a Crane Cams ignition amplifier that allows you retard the ignition curve when you are on boost, this is cockpit adjustable to compensate for different grades of fuel. I have 30,000 miles on my Vortech blown LT-1, (It has been run hard) and have had none of the problems described in these responses. Vortech is a great company, but I can't vouch for other companies.

 

Reminds me of my buddies old 93 Z28. Car had a 10 lb Vortech setup with a Carrol superfueler, 3 extra injectors behind the throttlebody, and alchol injection. Funny thing was it has stock exhaust, motor, rear, tranny everything was stock!

He would go by me at full boost and it didn't even sound like a V8, more like pushing air through a straw

The car did go 12.80's at 114 on street tires before the alchol injection seized up and losing the rings

You don't have to modify your engine to make nice power with a supercharger. If you want to make more power than the entry-level kits allow, then get ready to change some stuff. But if safely bolting on 100+ horsepower to a stock engine is your goal, it is perfectly attainable through ATI or Vortech.

Welcom to the board!

Tell that to the few hundred people on this board who are doing rebuilds or have done. They have solved no problems, what they say is total crap to get you to buy one of these things. Yes Vortech is a great company and they sell GREAT blowers, but theres no freaking way you can bolt 9psi to a STOCK camaro. First your injector just cant support the hp gain even with a FMU. Second the first time you detonate a little, the crappy pistons will blow, or the rings. Try to even run one on a 95 car with OBD 2 and maf max problems with out reprograming. Its a major pain to SC these cars even if you know what your doing.


If your bolting a hundred HP you dont think the stress on parts will go up in a equal amount. Its not just MAGIC HP. I dont like it when people say it totaly safe to bolt blowers up. LS1 I have no idea, they seem to be a bit better. It cost some people who read these post a lot of money when they try.

NOT FLAMING ANYONE!

Bill, good points. I don't believe that bolting on tons of HP can always be used with the word "safe" in the sentence. I do believe that having something put on properly, and treating it respectfully can minimize harmful effect - although not eliminate it.

I claim to have bolted on 150 hp with my ATI, but in all truthfulness I also did fuel pumps, 42# injectors, and tons of dyno tuning to get it running nicely with some margin for error.

So yes it's a bolt on - but no, it isn't like you just put it on and start your car and nail it. Well, I wouldn't suggest that....

I tell you, listen to the people on the board. I lurked for 2 years reading the blown section and decided an 8psi intercooled procharger on my low mileage 1997 would be fine for at least a year if I "did it right" => 42# injectors, Wideband for tuning, MSD6btm, bigger fuel pump, 1 heat range colder plugs gapped down, lt1 edit, boost and fuel press gauge, etc.

Put it on, tuned it with 0 knock running an afr of 11.3:1 (on the rich, "safe" side) and a max timing advance of 24 degrees from 5000rpm to 6000rpm.

Car lasted 2500 miles, running great but not drving it very hard. Once I was confident it was running well with no knock, I went out and ran it hard one day (3 runs from 0 to 130mph at WOT over a couple hour time period). Despite the scanmaster showing no knock and running on the rich side, I blew two pistons and scored the cylinder walls.

No matter what you do, a supercharger can, and WILL blow your stock engine. It doesn't always take very long, either. At 8psi, it isn't about "doing it right" or tuning it properly. The ring lands just can't take the cylinder pressures. Some people just happen to get lucky and have them last a little while!

 

Actually i've done a good handfull of supercharged cars and haven't had anyone blow a motor yet.. Thank God. I don't want anyone to hurt anything

I just finished tuning a 305 TPI 1990 twin intercooled 10psi car and even with 2 intercoolers I still noted pretty high intake temperature sensors.

For those who haven't had to tune a TPI car feel lucky, they suck to try to get off spark knock.

Again, some of the kits i've done even on stock motors have come out to whats about 10:1 and others way way way lean. I've come to learn that too rich is just as harmful as too lean

hell I even tuned a 91 Fox mustang with 36lbs injectors no fmu and about 150,000 miles. Its been living strong since january.

Just keep them at a good AFR and don't get greedy with timeing and you should be okay

 

I really Pray that mine stays together for a while.

I'm at 133k miles with 7psi (at least) with a roots blower. Non-intercooled

Oh well... i'll keep it way away from knock, and have it tuned perfect on the wideband and the rest is up to the man up stairs

I will probally put it together with some low compression hyper pistons, condition the rods and crank over the winter break.

If you haven't guessed yet i'm a little unorthadox

 

Yes you are correct, but most people dont have the knowledge you have. Considering you cut your intake and made a roots setup. Thats freaken insane, I would not know where to start on somthing like that. Just saying for the average Joe who thinks no tuning and stock injectors will do the trick is NUTS. Its just not a easy task. I have lots of tools and a snap on scanner still have problems from time to time.
