Twin Charging

[whooppee777]

could it be done with the blitz supercharger?

lol wanna try and get single charging working correctly first :D, And yes it can be done, but does the blitz displace enough air to even matter?

for the most part i believe mine is working fine i thought i had issues with my a/f ratio but i dont.

i dont know too much about twin charging other than it will be one challenging feat. and i'd like to thank turbo yaris for getting it in my head

the idea is great, slap on a big turbo to give boost in higher rpms and the blitz supercharger handles boost in the low rpms till the turbo has spooled.

my question, which i've already asked turboyaris but want others opinions, is wont the boost from the turbo charger have difficulty passing through the impellers of the blitz supercharger. (which i think is just another way of asking the question nexus just asked)

[turboyaris]

aww... you blew the suprise hahaha ;)

and yea you are both pretty much talking about the same thing, I would say, as I said earlier, I would get a little bit bigger supercharger, but thats just me.

Let us know when you get dyno readings.

no no no earlier today i asked u this and u never said anything about a larger supercharger, u said the blitz would do fine.


if i were to attempt this my goal would be 20 pounds of boost. with a built internals

[turboyaris]

nooo i mentioned that your supercharger was tiny haha and you should get a bigger one, I don't know for a fact though if you'd need a bigger one, I would need the actual specs for the supercharger you know. but for 20psi, I think you'd need to go bigger, anyone know the max boost of the blitz?

[Nexus1155]

yeah i would think you would definately need to go bigger especially if you are doing a decent sized turbo with internals. Think about it, you displace the air from the supercharger to go into the engine out the exhaust turbo makes its boost, forces the air back into the supercharger which the supercharger won't be able to handle the charge of air and it will be poo. This also depends if the blitz can take the charge, you would really need some charts or ask blitz or someone about it

You could get around this by using a different supercharger and redirecting air into the intake manifold directly and bypassing the supercharger all together. You would still be getting direct boost on the intake side and direct boost on the exhaust side.

Just mentioning the standalone management you will have to custom wire and program to manage the system.

VERY expensive project IMO.

[whooppee777]

expensive but possible

The thing about twin-charging is that if the turbo EVER boosts higher than the supercharger, the s/c will blow comprimising your whole engine. And the fact that the s/c can only reach a certain boost, where as the turbo can, in theory, hit any boost level, is place for concern. So if your rpms climb high enough and the turbo hits higher boost, your screwed. But if you have a waste gate that wont fail you, you'll be fine.

Boost Controller

[coheed]

But the way he was talking about it, he wanted the boost form the s/c on the low end, and the boost from the turbo on the top end. But it would be pointless since you cant boost the turbo higher than the s/c at any point in time. You would have the same boost pressure on all ends. Just my opinion.

[turboyaris]

actually, the supercharger has a clutch style pulley and actually deactivates at a certain rpm, at which point the turbo has built full boost and brings you on home

[turboecho2005]

A centrifugal supercharger would be the way to go. Not a roots type like the blitz...

BTW why not triple charge while you're at it ;)

Twin Charging as always been a dream of mine and i am sure one day it WILL happen...

[largeorangefont]

It is a waste of time and money on a high compression NA engine like the Yaris has.

You would NOT want a centrifugal supercharger, that defeats the whole purpose of twin charging. YOu woudl want a roots or twin screw type supercharger.

Also, one will not "blow up" the other.
