Why supercharge over turbo? Why do so few people turbo? whats a safe and cheap way to boost my car to just break the 400 mark? Im not lookin for a heavy duty supercharger that can handle 20 pounds of boost just something thatll be reliable at 5lbs.

All I can tell you is that with about 11PSI of boost from a S/C, you'll be hitting about 450-470RWHP. S/C are more consitant in power, but a Twin Turbo Setup can give you a more HP over a S/C, but you'll need forged internals to be able to handle 500RWHP, and a TT setup will run you down about double the price of a S/C

"Turbo" sounds more at home on the imports and rigs. I've also read that you have to be extra careful about general engine wiring and plumbing because space is tight and the temp can be super hot.

There's a company that can install your turbo further back on the underside of your chassis with the intake somewhere near the gas tank or fender. They use a smaller charger to reduce spool up time.

I'll be back with the link...

In the case of a twinscrew S/C you have instant power because it runs off your engine RPM rather than heat expansion from exhaust. Twin screws are at peak from around 2,000-6,000 RPM were as turbos take time to spool up.

one main reason people choose a S/C over a turbo is for emissions. most turbo kits are for offroad use. if you want room for the future with more power turbos are the way to go. everyone knows turbos make unreal HP and torque. S/C are no more consistant in power than a turbo. a single 62mm turbo shpuld be good to 600hp . the kit roadrunner is speaking of is the STS turbo which is a remote system. there is no such thing as turbo lag like the old days. you guys need to ride in a turbo car you will see. turbos have been around for a long time. every big rig has a turbo in it and turbos can handle some mileage. go to turbomustangs.com and have a look.

if you want to stay safe around 5-7lb of boost you might want to look into the saleen charger from JDM.

A roots style s/c at about 5lbs boost will get you 100hp gain starting all the way down at 1500rpm or so. Cost you around 4k. I'm partial to Roush.

Where did you get your data from!!! If you go with a turbo you will be able to adjust your boost from inside the car, with the S/C your stuck with the boost that the pulley put's out!!! A t-62 turbo will spool fast on the 3v and yes they are emissions legal. Yes you will make more power with a turbo and there is know more matinance than a supercharger. Check out turbotechnology.inc or hellion turbo systems. Either way ya go you will be happy.

ok good info but lets get right down to it. I want to be at 400 hp what are my options and i am on a semi tight budget. Not sayin i wana slap a unreliable used s/c on my car but at the same time i dont need something that is capable of rediculous power when im never gonna use it to that potential. Should i go with forced induction and stick with the stock wheels and get some sticky tires or spend the money on simple power adders such as intake, pullies, h pipe, axel back and get it tuned and buy some new wheels with some wider tires? and yes i know its whatever i want but i just need to know which is gonna be the most bang for the buck.
Will the bolt ons i listed even come near 400 rwhp?

[GTNorm]

I'd say your tight budget keeps you out of the turbo world.

I think yoiu quoted the wrong person

this is a good point that ALOT of people dont realize - turbo power is inconsistant. Thats why so many (just about all them) who put a turbo on a non forged motor blow it up in the first month. The turbos are also harder to install and tune. Really the two setups are a matter of preference because both can one up the other in different setups, however one thing remains constant.... turbos cost more.

[ChrisJ]

Superchargers are cheaper and easier for most to tune...

They make less power and are less efficient then a turbo but like said above turbo systems are more expensive and somewhat more of a pain to install and tune...

If I had my choice I would go turbo but I went supercharger and I am just as happy for now...

[Luis_GT]

Well, a TT setup is more efficient than a single Turbo setup since they don;t suffer from turbo lag, they may be inconsistant, but they can be adjusted for more power with a flick of a switch. Although harder to tune, I love the sound they produce. A S/C is better in both price and power, but you have a fixed amount of power on the car, and the pulleys rob a little bit of power.

I would go with a S/C to not have to use Forged internals and the cost. Of corse, up to a point, after 470-480RWHP, you'll want forged internals.

[TDog]

I like both. After going thru both installs, I'm a little partial to superchargers though. The turbo channels some very hot pipes into the engine compartment. So hot, in fact, that there is some serious heat shielding going on to protect anything that even comes close to them. I would not be surprised if the engine compartment on a turbo running car is far hotter than that without. Much of that super hot air is going right back into the engine too via the intake. Remember, we are talking about air right out of the header. Hot stuff…channeled to a turbine under your hood.

[nem]

turbo power is not inconsistant to superchargers. and this is not a reason for blown stock motors. there are to many varibles for blown stock motors, ( tuning, fuel, etc.) turbos are known to be torque monsters compared to a supercharger. a supercharger doesnt produce the torque like a turbo.look at the dyno numbers they speak for themselves. they create a ****load of torque and the stock rods are failing because ford shafted us on the rotating assembly. there are a lot of people with centris and twin screws with blown motors. pricing between the two are pretty close depending on what manufacturer you chose. you can adjust the boost quicker on a turbo but not more than a few lbs without tuning. emmisions is a big factor there are a few that use cats but most are offroad use. i wish mike @ powerhouse would make a kit utilizing the stock cats or something cause i would be on the kit like a seagull on a frenchfry. you will have a hard time hitting 400hp N/A in our cars. heads, cams, headers, CAI. UDP. etc, you will spend more money than just going to FI. check into a saleen from jdm or the Roush charger like grabber stated.

let me post this old video and you make your decision.

Turbo FTW!, damn that was a great race.

[TheUNZippee!]

Bottom line:
Superchargers of the roots type or twin screw variety make great low & midrange power and are excellent stoplight monsters. Turbos & centrifugal superchargers are excellent midrange - top end tools, and are great for highway blasts.

finally that is what i was thinking the whole time i was reading...i dont see myself doin top end racing.. so to me a turbo is unpractical.. the heat from it is very extreme a tt in our car is tight as hell... tuning and everything is a bitch... i say make the beast wat is best for wat u want....
my opinion. i just see no point in top end.. where i live.. even on the long island expressway which is nice for cruising and all i dont see anytop end, once i hit like 100 boom im on the brakes cuz otherwise i have no time to stop and at that point id slam behind some1 or get bagged by cops cuz u wont stop in time..

[TheUNZippee!]

Exactly jat. It depends what you are int to and how you use your ride. If you are in town all the time, a supercharger of the roots type or twin screw, like a Whipple, is the way to go. If you are on the highway all the time, like me, a turbo or centrifugal blower, like a procharger, is the way to go.
