im torn between the hellion turbo kit and a supercharger kit...both systems will give me the same power out put but the turbo comes with a tubular front end w/ coil overs...i believe that the hellion kit is 5500-6000 an an s/c with a similar front end is about the same price

which would be better...and this is a street and strip car

 

your gonna get more torque with the turbo then a supercharger. turbo is more effecient anyways. dont have to worry about belts getting destroyed. i looked into a turbo for next fall after i put the built bottom end in. ill prolly get the turbo b 4 you

 

you probably will...im getting ready to go to colllege..haha

(i dont wanna hear save ur money speach...seriously..i have a seperate account for my car and another for my college)

 

Turbos are nice for our cars but its all top end power. you turn your car into a "highway racer" and alot of your power will be from a roll. Your car should trap around 80 in the 1/8, and with a turbo you can expect it to be about 100 in the 1/8 to give you an idea. Screw hellion, wait for MPH's turbo kit to be available. You can buy the single now, and upgrade to twin down the road with a couple extra peices.

 

until the MPH kit comes out im still with hellion. i know rhonda will be nice enough to mail to APO.

the only supercharger he could buy with a k member and coil overs is a centri and those have the same type of power (i.e. power comes on at 3k and up)curve cept that the turbo has way more torque.

 

I'd go S/C if I was you... instant power...

I don't care for turbos...

I'd rather stick with NA power myself...

You can do heads and cams much cheaper and have plenty power

 

positve displacement blowers give instant power. not CENTRI's. the dude asked about S/C that have the same front end as the turbo kit and the only one he would be able to afford with 6k is a centri kit. if he dropped the k member and coil overs off the list then i could see a KB intercooled kit which would be funner. a high stall or 5-6k rpm launches take care of the low end power.

im not impressed by head and cam changes for modular engines. to little gain for the dollar.

 

With kenne bell you can be making full boost at 2300 rpm.

 

Im glad I went with the centri ! I like the power delivery.

 

who is this comment meant for. if you read whatever i put in my posts i never went against a KB. its just the fact he set a 6K limit for cost and install i assume. the only thing he can afford with a K member and coil over is a centri.

if he took the k memeber with c/o kit then he could afford a KB 9 psi kit.

this is just up in the air stuff for this guy. he has to pay for his college first.

 

wow there is a lot of mis-information here.

First, lets look at the three types of Forced Induction.

1. Positive Displacement Supercharger (aka eaton KB whipple)
Pros: Near instant boost, (aka boost off idle) peak boost is generally made between 2000-3000rpms.
Cons: This is the least efficiant Type of Forced Induction. Although peak boost is made off idle the blower becomes less and less efficiant as it spins. Basically starts awsome then just kinda drops off as you Rev. This Supercharger makes the least ammount of power. Also, as with all Belt driven Boost, there is a lot of Parasitic loss (need power to make power)

2. Centrifugal Supercharger (aka vortech Powerdyne Procharger)
Pros: Makes better power then the Positive Displacement Supercharger, no "spool" like a turbo, meaning you can put it in gear and press the gas down and you make boost, the boost you make will be heavly dependent on RPM, but it will happen. Unlike the Positive displacement supercharger, the Centrifugal gains boost as the RPMS increase, and makes more boost the more RPMS. Cent's generally make more power then Positive Displacement
Cons: You do not make peak boost untill just before you shift, so your only at peak boost for a second. so an 11psi kit will ONLY make 11psi @ redline (or w/e you shift) Also, just like the Positive displacement Supercharger, it is belt driven so the parasitic loss makes it fairly inneficiant because it takes power from the motor to make power (2 steps forward 1 step back)

3.Turbocharger (garret etc)
Pros: Most efficiant Boost possible. Also the most customizable and flexable. Depending on how the kit is set up you can make boost off idle (like a Positive Displacement) or you can make peak boost at 3,000rpms or whereever you want! It is all about how you set it up. A properly set up Turbocharger will make more peak power, more peak torque, and more power under the curve then any Supercharger.
Cons: Spool, it takes a few seconds for the gas to build up enough pressure to spool the turbo to make boost, Spool is dependend on the type of turbo, size, ball bearing or not etc that you have. This means that for a split second when you step on the gas, there will be a SLIGHT hesitation before you take off. In a well set up turbo car it is not an issue AT ALL. Only in poorly setup kit do you feel any of the feared "turbo lag"

I hope this clears some stuff up. Because Turbocharging is prolly the least known Type of Forced Induction, most people misunderstand it.

Look at these two dynographs, same car. One is a turbocharger @ 8.8psi the other is a Procharger @ 11psi both intercooled.

Which one of those would you like to have?
