I disagree, the turbo will definitely blow your engine before a supercharger on these 2litres.. also depends on maintenance etc. in my dads miata club, the turbo engines start blowing way before the supercharged ones and there are a LOT of both types of engines done up by a bunch of pro's

and I'm not saying the superchargers better, I for one like the turbo

 

It all depends on set up and baised on what is currently available for both turbo and superchargers the superchargers will help with a longer engine life. I dont see any turbo companies giving out year warrinties.

You have to look at what happens to the compressed air once you let your foot off the gas. In both cases it goes through a blow off valve. The difference is when air from a turbo goes into a engine the blow off valve only lets out that is in the intake piping but the remainder of the air that is in the throtal body and manifold is still compressed...yet the computer already eased on the gas flow to compinsate for the lesser needed fuel because it read a lesser amount of air. Im not going to get into the effects that more air then fuel in your engine has, and sure your probly thinking...It cant be much cause that is only when you let off the gas. Over time you will start to notice plugs fouling freakuantly and carbon build up.

There is a soulution for this. (Dont remember the name of it) Basically what it is though is instead of using a blow off valve the turbo is always running to some extent so that the computer can always sence the proper air flow going to the engine and realease the proper amount of fuel...down side you dont get that pssst noise from teh blow off valve that everyone loves. But hey its way better for your car


A supercharger works on a simular matter It is always running and therefor always has the correct air/fuel ratio (in moderation)

Yes the supercharger ads load to your crank robbing you of power in a way so does a turbo by restricting the amount of exhaust out. Either way your going to loose. One thing you have to look at is WHP. A turbo from RRM will give you roughly 230whp on stock components. (correct me if im wrong) The Ripp Mods superchargers will do 230 for the stage 1 and 275 WHP for the stage 2 with stock internals. The RRM turbos run 12 psi of boost (again correct me if im wrong...maybe its 11 maybe its 15 I'm not 100% there), Regardless that is more presure then the Ripp mods (less dammaging) 9 psi supercharger is doing. Now tell me what is more efficant....what is causing less load on your engine? besids you could always take your AC out and put there pulley in their place. That would make up for the 30hp dont forget about the under/over drive pully's that come with the kit. 30hp is nil to loose when you over all WHP is 275.

 

From what I have read from 'Turbo' Magazine last month edition, they said that supercharger take away "AT Least" 30HP off the start. All of these problem caused by its mechanical structure, namely belt driven.

 

When you attach a turbo to your car it uses the exhaust to turn the turbine. Don't you think that that restricts the exhaust at all? Do you believe that a turbo is a way of adding power without taking any away before hand?

 

BTW mrauqinas I respect you, dont think otherwise I just want to show my points aswell. [wanted to clear that up]

 

this is why there is turbo lag is it not the engine needs to be in the higher RPMs in order to give that exhaust pressure that the turbo utilizes???? correct???


i honestly have know idea!

 

Yes, turbo lag is that the turbo boost up your wheel power only when you rev your engine up, namely while the intake suck up the air and turn the turbine. However on the low RPM , that is when the turbine not spinning fast enought to create a strong boost (turbo lag), it will create almost the same preasure of O2 as CAI but condensed.

Danno, don't worry bro. No hard felling, Im not an expert either - just sharring opinions and experience

See you @ the meet this Saturday

 

got the car on friday and its awsome. i took a couple of guys that have and oz (stock) ok intake and exhaust. what did you guys think?
i still have to do my exhuast and maybe a fuel pump, but before that i think i want to do my brakes cause i think ill burn them out first

 

Ya definatly get that stuff done. The car is Sick and very fast. You need bigger brakes too. I was scared when It was time to stop. LOL
