So u want to go to turbocharged power, but don't think you can? You've heard its way too much trouble and too expensive. And I am sure you've heard a Carb he did try a piston he did fry. Well in this page were gona show you examples of why and how you can turbocharge, and why you should.  Plus try and show how u can do it and not spend your kids tuition doing it.

There are 3 well known poweradders: NA, Nitrous, and Turbos ( superchargers). Here is why turbos while expensive are a great choice and now being all the more common. Lets say u want a 9 sec drag car, and you have these 3 choices on how to build one.

Natural aspiration is relying on natures 14.7psi to feed the motor. To pull in as much air as your can you need compression, monster cams and valve train. Plus very loose converters and tons of rear gear.  Usually people in this class will build a big block, bigger the motor more air u can get.

Now lets look at nitrous. The nitrous setup will get a smaller motor to your 9 sec goals, they still love big duration cams, big valve springs, and loose converters, and gear. Both these choices work great and will get you your goals of a 9 sec Drag car. But now u wana drive your drag car on the street. Welcome to turbos!!!!!!!

Turbos work best by load, so u have a heavy car, No problem. They like small cams, small tight converters, lower compression,  Higher gearing (3.08-3.50 works great). So now your 13;1 motor with a .650 lift 270s dur roller, 245psi seat pressure springs, and 5.14s are not needed at all.  Now you build a basic reliable motor that's fun to drive, gets great fuel mileage, is very easy on parts, and u let the boost pressure do the work for you.

Superchargers are the middle men. they fit right between turbos and na. They do tend to like big cams and do like compression sometimes. reason being is you have to drive the supercharger. now this in some cases can take 500-750 hp to spin like in case of a procharger f3. but for 9 seg goals u can use a f1 and proably about 75-100 hp to drive it.

Im not here to decide how you go fast, just wana help u to see that going fast don't mean killing your cars street drivability or reliability. And the first time I was pulling on the loud open header drag cars and dragsters in my street truck, let me tell ya its a addiction.

I will be working on this page and updating as I learn. Im here to help and answer questions as well so if you have any just ask. and likely ill be covering them in the page.

Turbo Basics 101 a crash course in tech.

 

Turbochargers rely on exhaust pressure to power them. This is the hardest part of any turbo build cause u have to get all your exhaust to your turbo. This in most cases will require a custom header, and crossover for singe turbos or custom headers for twins. But we are finding there are a few places to get cheaper manifolds that will require only slight mods.

The turbo is composed of a compressor wheel (cold side) and a turbine wheel (hot side) with a common shaft that connects them. as your exhaust enters the exhaust housing it forces the turbine wheel to start spinning, as it spins you compressor draws in air.  the harder you spin the exhaust the harder and more air you draw in. What some don't know is evan at highway speeds and just cruising around the turbo spinning draws in extra air and gains VE volumetric efficiency.

Turbo Sizing to your engine is very important and many of the lag issues weren't the the systems fault but the turbo was too large comp too low or cam too big. picking the right turbo is important for a great working system. the best place to start is knowing your power goals. type of racing or just street fun, engine specs and vehicle type and weight.
