The only thing i have against the revhard turbo kit is that it comes with an intake and i just bought one so that's a turn off. But the blitz you can use your intake, buy a header, have different levels of boost, and overall i think you'll have more power than the revhard by far with those mods.

 

ok first of all with a turbo kit you can have any level of boost you want you just can't go lower than the wastegate is set, a supercharge is set for one boost level, the boost level of a supercharger is determined by the size of the pulley so unless you happen to have a pulley that can magically chnage size you aren't gonna be able to adjust the boost of a supercharger without changing the pulley, and second you will see more horsepower with the turbo setup b/c you can adjsut your boost and i'd be willing to bet thay 7psi from the turbo will be more power than 7psi from the supercharger and also you will get less lag with the turbo

 

for some reason i thought boost on a supercharger is more powerful than a turbo.. if a s/c is boosting 6psi and a turbo is boosting 6psi... wouldn't the s/c'd car be faster because it's all through out the rpms? plus supercharger looks cleaner on these cars cause there's not much room for a turbo setup. supercharger looks nice just sitting in front of the engine. :D

 

well it depends on the size of the turbo and supercharger you are using, it depends on the flow and effiecency of the chargers, and a super charger is not faster , generally, and here is why, a supercharer produces linear boost, a supercharger will start spooling low but will never hit full boost until redline, that is how they work, while a turbo charger will hit full boost at say 3k and hold full boost all the way till redline, so let's say your turbo car at 4k is at 7psi holding till redline your supercharged car might be a 2psi at 4k and won't hit 7psi till redline

 

[quote="peppy"]couldnt understand that..

i think he means less lag with a s/c..

or less lag with a smalle turbo...

one or the other.

 

i'am going with the s/c myself

i don't see too many top fuel/funny cars running turbos.
i know the scion isn't a drag car, but i like blowers/superchargers better.
linear power and better launches.

 

[quote="TheRedBox"]a supercharge has more lag than a turbo , as i said earlier a supercharer will not be at full boost till redline, it slowly build boost, a turbo takes a few thousand rpms but then it kicks in and has full boost all the way to redline, my friend had a supercharger on his gti and i didn't like it, it was fast as hell up top but down low it wasn't all that, he didn't start seeing boost till 4k while my jetta with a turbo has full boosted by 3k and held it all the way to redline

 

Hey hey, there's my baby!!

I'm running the Blitz S/C kit in my dealer's project car right now. It's awesome...lots of fun and so far we haven't had any problems with it.

Having the clutch switch is really neat...it's nice being able to run it N/A and control the % of throttle response.

I had a link up here before to my imagestation account with lots of pics, I'll see if I can dig it up.

To the best of my knowledge, the blitz kit is a positive displacement style charger (aka, roots supercharger). IE.....full boost at low RPM.......ie........more low end power.......ie.......less lag.......ie.....quicker off the line. Downfall? Parasitic power loss in your high end.

Describing the behavior of a turbo charger is one thing.......because for the most part....a turbo is a turbo is a turbo (there's some variation in types, but in general, they all act roughly the same). However, you have to be careful when describing the behavior of a supercharger.........because there are different types of superchargers, and each one acts differently (roots, centrifugal, twin screw).

Peppy.......what you've said may be true in regards to centrifugal style superchargers such as the Power Enterprises charger (basically a turbo that is belt driven). A centrifugal acts more similarly to a turbo.....building boost with RPMs.

yes you are right, most of my experience is with centrifugal supercharges, but roots chargers are also linera boost and i'm not a fan of linear boost, boost takes longer to build with a supercharger

 

Superchargers are more responsive on street cars hands down......

with supercharger you dont have to rey to 3k and drop the clutch cause the power is there all the time with a supercharger....

Ive seen too many races where supercharged cars pull harder off the line then turbo cars cause the turbo car ws spining tires when they dropped the clutch....

I know spining tires is "cool" but not so "cool" when money or a reputation is on the line...

Go for a ride in a roots supercharged car and you will have nothing more to say about them not having low end power. They get right up and go. Centrifugal superchargers behave pretty much how you're describing Peppy. From what you've said you'd probably love a roots style in a Scion. I've put a jackson supercharger on a new Civic Si and an Alpine SC on a Tiburon V6 which are both roots style and they give the cars an almost electric feeling with how the power is right there. Super fun street driving.

 

i dont understand what thats for?

 

a turbo is harder on the engine because it boosts at a certain rpm when a s/c is constant power as the engine revs. No need to spool up a s/c. I would go with s/c all the way on a scion

 

Some guy on cardomain has an echo hatchback with a blitz compressor, with a header, plus exhaust, running high 14's and i typed to him he says he does 0-60 in about 6.9 seconds. He has low profile tires on 15's, so speedo might be off. But 6.9 is respectible. He has a 5 speed.

 

Or Pink Slips.

For those of us who live life a quarter mile at a time anyway.

 

hypothetically speaking... what do you think someone would run with short ram intake, headers, cat-back exhaust w/ 2.25" piping, on 18's on an xA?

in the process of a getting a loan for the compressor, so hopefully i'll have it within a couple months. :D

don't really want a turbo cause these cars can't go past 120 cause of the gear ratios, 5th gear will only pull you to 120 before it hits the rev limiter or redlines, so why not just build up your bottom end power? seems better that way.

 

How much does something like this cost?

 

Not to mention this car isnt built for that kinda boost. The cost alone of building the bottom end, remapping the fuel system and worrying about blowing your engine every tim you run just turns me off of a turbo system in a scion. I just cant see that kinda cash dropped into the car as logical. Maybe I will change my tune later on when there are people exploring the limits of the car but for now I will go with the reliable 40 to 50 percent gain.

I JUST WANT A BLITZ COMPRESSOR! NO MONEY!
