Vortech Superchargers

Re: Vortech Superchargers

What all components do I need here? Does it matter whether I have a Blow-Off Valve vs. a Bypass Valve? Do I need an FMU or will the right tuning take care of that? I've got Accel 44lb Injectors, and NGK TR6 Spark Plugs. I also managed to find an LS1 MAF and Throttle Body, do I need these? And I'll also be picking up a fuel pump soon as well, most likely the Walbro 255 that everyone suggests.

I'll also be doing a custom exhaust as well. Whether or not the exhaust and supercharger go on the car this spring/summer or next winter depend on how much I have to spend.

Re: Vortech Superchargers

The correct pump and tuning should take care of the fuel, no FMU required. the LS1 maf could be useful depending on what year your car is. BOV is cool to have and is almost required if you have a manual.

Re: Vortech Superchargers

Isn't a good S/C more reliable than a strong turbo system?

Yes in most cases it is.

Re: Vortech Superchargers

Yes in most cases it is.

How do you figure? That may be the case in this community because people are doing a turbo kit for the first time and using used parts and junkyard pieces.

Technically speaking turbo's have less things to actually go wrong.

You need to do a lot more research if those are the kind of questions you're asking!

Injectors will be fine, all tuning can be done with HP tuners. Plugs depend on boost really and how cold you wanna go. LS1 MAF yes, LS1 TB no. Go for a Racetronix fuel pump.

Re: Vortech Superchargers

those questions were more to clear everything up than anything. The first was geared more towards which would be better, blow-off or bypass valve, since I see/hear more about blow-offs but Vortech mentions bypass valves.

The second was because I didn't have a complete understanding of why you would need an FMU when I have plans of a proper tune.

I'm asking the questions because I am in the research phase. I have aquired most of the parts I have through deals that were just too good to pass up, where I could just sit on the parts for some time while I collected the rest and researched the whole project..

Re: Vortech Superchargers

That is a ridiculous comparison. Hardcore racers use blowers because they are generally less restricted on weight using blower where turbos are given weight penalties because they make more power. There are also usually big size limits.

You can't compare one car to another in a race, tires, suspension, driver, transmission, weight etc.. all play their part. I would put my car up against any car on this site on the street and be very confident.

And of course superchargers have intercoolers!!!!!




ANY boosted application will be heat soaked when not properly intercooler. Roots blowers are the WORST for heat soak of any forced induction method.

That's nonsense about weight penalties. What about Supras or GN. Never heard of that. Some SC have intercoolers not all. PD doesn't have them, and probably doesn't need it since it runs cooler. Root blowers does get heat soak, but that depends on the application. I used to have a GTP with 8psi and I DD that everyday and I put anywhere from 60-120 depending if I have school or not. No heat soak there. Yet, Root blowers are still the prefered choice hardcores.

If you run a bypass valve you will be recirculating back to the take. If BOV you can let people know they might not want to F*** with you lol.

See about the weight penalties.


Not all Turbo cars have an intercooler either. I've had a few SC GTP's as well, they get heat soaked bad, but they still work...

A properly done Turbo car will be just as reliable as a CSC or a roots car.

The FMU generally just gets people by until they can install injectors and tune them. You really dont need the LS1 stuff unless your adding methanol injection IMO. A BOV is less complicated to incorporate using the stock MAF setup. This way you can put it on just before the throttle body and the air has not been metered at this point so it wont affect driveability.

That's different kind of contest. Those cars have been shelled out, but nevertheless there are still turbo cars running in those categories.

Most Turbos have intercooler. They need it or else they get horrible heat soak. The average turbo spins 2-3x's faster than SC and they are next to a compressor which is extremely hot.

Re: Vortech Superchargers

Turbo does have it's advantages when it comes to dialing in the boost. So if you have turbos you better be running more than 10 psi on it. If it's low to medium boost it's not really worth it, SC will do nicely.

Which oness more effiecent at low medium boost, turbo is , due too no parsidic loss in the drivetrain.

That's because you are running yours open. Try running it through your exhuast and you'll see some parasitic lost.

What are you talking about man. 10psi is LOW boost. If you boost your 3800 you better be hitting at least 10lbs or it's not worth the $$$!

Look through the Powerdyne section of this site. It should give you an overall idea of what all you'll need for any CSC application. Just ignore the parts about the Powerdyne hardware.

My Z car came stock with a non-intercooled T3 that runs low boost (~7psi). What little heat soak it sees is in the intake from the hot coolant coursing through the block and heads, rather than the air being pushed into the intake from the turbo. Granted, this is because it's at the designed low boost and stays cool, along with spooling up fairly quickly. Once it's turned up beyond its efficiency range, then yeah, heat soak will become a problem. But right now I'm not concerned with it, even in the summertime.

Heat soak happens with intercooled cars too. Sitting in traffic with no airflow over an intercooler will cause it to get hot and heat up the air going into the intake.
