There is no doubt that supercharging is one of the best ways to build reliable good horsepower from a street engine. Done the right way you can add 300 horsepower to the engine in your muscle car; while having the dependability to drive it everyday.

Having almost done away with parasitic loss; the efficiency has gone up about 30%; allowing the supercharger to generate more power. We all love horsepower in our hot rods, we love to go faster any way that we can.

If you match up the engine build to the supercharger, and take in to consideration what your trying to do with the car; you may end up with the perfect car for you. A supercharger is one of the greatest things on earth for a muscle car.

You need to match up the camshaft, and heads along with a few other things, such as the right compression ratio of pistons in the about 9:1 range, and forged rather then cast. Make sure that the bottom end of the engine is strong; use a four bolt main block.

Street supercharging can provide you with years of great driving enjoyment. You should always use a forged steel crankshaft when building a supercharged engine. Make sure that you buy carburetors that are specially built for a supercharger engine.

When supercharging a V8 engine; you don't need to push major boost to develop the power. About 7.5 - 9 pounds will work for the street with most street superchargers. This should develop all the power that you need, while still being able to use pump gas.

If your going to use a fuel injection rather then carburetors, you will need to match the fuel injectors to your camshaft and heads. It's imperative that they spray just the right amount of fuel; or you could lose some of the power that your trying so hard to build.

Also when street supercharging timing is of the utmost importance to building power. The camshaft that you buy should come with a cam card; this car will tell you what the optimum timing is for that camshaft, if you do everything just right your car will be a beast of the street.

Rather you use a carburetor, or fuel injection you should make 100% sure that your air to fuel ratios are set correctly. The aim of setting these is to get the fuel mixture as lean as possible, without burning your pistons; this is the optimum setting for making mass power from your engine.

Make sure that your supercharger drive speed is over driven, or under driven right for your application. Obviously if your trying to generate power, you should over drive the supercharger. I usually recommend 8 - 10% for street engines.

This means that the supercharger would spin 8 - 10% faster then the crankshaft speed of the engine. You should talk to the person who's building your engine to figure out what you want though. Always consult with a high performance engine builder when you install a street supercharger.

This is just a few tips; it's not meant to make a you an authority on superchargers. If they are installed wrong; the damage to your engine will be massive, do yourself a favor, and read up on it a bit before your attempt to install a street supercharger.

Their is noting hard about it, all you have to do is pay attention, and make sure that it's done right. Make sure that you spend a lot of time when you install the distributor; an intake back fire can ruin your engine if the pop off valve malfunctions.

Take all of these things in to consideration when you build your engine, and everything should go fine. This is far from everything; but it's enough to get the job done. Take your time to build it right, and your street supercharger should do everything your want it to.

Street Supercharging

I've been in the automotive business for about 20 or 25 years, I have worked in all facets of the industry, from parts to restoration, all different makes and models, I just want to keep people interested in the old cars because it's where my heart is.

Beefing Up at the Wrong Time

Pontiac intends to beef up performance; this is why the automaker will be unveiling two new rear-wheel drive powerhouses at next week’s New York International Auto Show. But experts say the beefing up was made at the wrong time.

Amid rising gasoline prices and the intensifying global warming issues, shoppers’ appetite for gas-guzzlers are curtailed. Timing couldn’t be worse.

At the New York show, Pontiac will showcase the 2009 G8 GXP featuring the new 6.2-liter small-block V-8 engine generating 402 horsepower. According to the automaker, the G8 GXP sedan, set to go on sale this year, will be able to go from zero to 60 mph in 4.7 seconds. The new sedan is also equipped with a specially tuned suspension and an optional new six-speed manual transmission.

Aside from the performance sedan, the automaker will also introduce the 2010 Pontiac G8 sport truck, a two-seater built on the G8 platform with a 73-inch cargo bed. The sport truck, which will arrive in dealerships late next year, has the same 361-horsepower, 6.0-liter V-8 used in the G8 GT sedan.

"There's simply nothing else like the G8 sport truck on the road today, and we definitely believe that there are customers who will be excited by its distinctive design, performance and cargo capabilities," said Jim Bunnell, general manager of Pontiac, Buick and GMC.

Pontiac, the struggling brand of General Motors Corp., is freeing its high-performance G8 family to bang sales doldrums and to repair its image. But the new corporate average fuel economy (CAFÉ) standards could hinder the plans.

Aaron Bragman, an auto analyst at Global Insight, now considers the maker of Pontiac radiators the most at-risk of General Motors' brands. "The renaissance was on the books, but it's basically been thrown into confusion with the new CAFE rules," Bragman told MSNBC. "The future depends on what they can do with Pontiac. Can they make it a four-cylinder, turbocharged brand, or are Americans so set on it being the rumbly, rear-wheel-drive V-8 division that anything else is not going to fly?"

Jack Nerad, executive market analyst for Kelley Blue Book, said Pontiac's return to its performance roots is a positive step, but years of lukewarm vehicles have made the brand irrelevant to many consumers. "They're on the brink of either great success or marginalization," he added.

"Pontiac has always been about style and performance. There have certainly been times that we've fulfilled that mission better than others," Nerad concluded. "We're again getting the vehicles that fulfill that mission very clearly."

What do you think of the Chevy 400 Small block?

I have a 1973 Chevy Caprice classic convertable that I did the body work too and put on a new top. that last thing I did was rebuild the 400 sb under that hood with a 750 CFM edelbrock carb, edelbrock performer intake, double roller forged timing chain/gears, and a medium cam with roller rockers. I happen to love the great power i get out of this engine but I would like to know form people with more experience than me what you think about this siemese cylinder engine?

I had a 67 firebird with the 400 and 4spd tranny. I raced it in Hawaii for 3 years at the dragstrip. stock it was just a little better than my friends 68 camaro with a 350 and 350 auto tranny. I took the rochester carb off and tried a 750 double pumper with a enki intake and timing gear drive conversion. results were better but not what i wanted. Changed heads for some with larger intake and exhaust valves put roller tips on and had them polished. results about the same as before. added headers and switched to twin 2 barrel carbs by webber, with a webber intake. added velocity stacks to each carb. exhaust changed to hooker with 3 inch collectors and 2 inch straight pipes out in front of the rear tires. dyno tested at 435hp still sluggish off the start and had a problem with the close cylinders getting too hot. hot laps in 90 degree weather did'nt help. added material to the outside of the cylinder walls to help spread heat. any good welder can do this for you. got some extra cash and bought a whipple supercharger for it. added a predator carb and a new msd box. mind you this was in 1988 I think it was a msd4 box. rebuilt lower end and bore out to larger size changed crank to a forged model i think it was made by white. elderbrock cam with increased intake duration stock height and tall exhaust with short duration. 9.5 to 1 compression. dyno tested at 608hp and promptly blew the cylinder walls. Bought a 350 case and bored it to 383cid installed all the goodies from the 400 motor and dyno tested at 593hp. if you want big hp out of a 400 stay below 500hp. its a good engine if you keep the heat down I had a oversized radiator and fans on both sides, wraped the headers and and a oversized oil pan. heat is what killed it. I ran it too hot on the dyno. on the strip it was okay because I kept moving if I would stop and park it after a run it would seize up until it cooled. what a pain in the but that was! if you want a big mouse motor I would go for the summit special 383 motor because they reinforce the case and do all the right stuff to make it last. oh that firebird ran hi 9's at its best. now I have a fiero with a built buick 231 v6 motor and a 2 speed tranny. 465hp 400foot pounds of torque and I can run low 9's also have a 2.8 liter diesel jeep liberty which is now producing 300hp at 540 foot pounds of torque and runs 12's and still get 20 mpg.

Musings on Kids and Asia
By Vitaliy N. Katsenelson. I have not written articles in a few months, except for the one I wrote for the July issue of Institutional Investor magazine, on Japan (I'll post a link once the magazine comes out).. I am sure Freud, after spending a few minutes in my subconscious, would provide some disturbing explanations. But as Freud said, sometimes a cigar is just a cigar. I've just been ...
