Guy's
I recall someone in ZTH did this Twinscrew setup before. May i know who it is? Need to ask him few thing

May I know what is the twinscrew?

 

[cuscostrutbrace]

if you mean CENTRIFUGAL type supercharger,i think its Benjamin (adaptronic seller) done that before..

i think it's the same as kompressor system used in mercedes benz rather than centrifugal type... let's thread starter verify

p/s: sorry non toyota user here

 

[normality78]

yup, like benz compressor type. I didnt know Benjamin did the centrifugal type before

I have done setup for autorotor 0.7litre twinscrew, Raptor supercharger and ASA centrifugal supercharger for 4agze.

Mercedes Benz is using root supercharger, MP45, MP60.

 

[miriguy]

of all the superchargers, which is the most powerful of them all?

 

[synchron]

I would say autorotor twin screw, Raptor centrifugal powerband is from 5000 rpm onwards.

My next project will be twinscrew on my SC400.

 

[miriguy]

autorotor twin screw, Raptor centrifugal... easy to obtain and mod into 4agze
im currently using sc14 and its going to KO-ed soon. getting clucking noise from it after i went to dyno last week. maybe the dyno run is making it like that now. my boost is now only at 0.7 compared to 1.4 on top intercooler.

 

[synchron]

i think you over rev the supercharger. SC 14 max supercharger speed is 10,000.

How HP are u making on the dyno machine? Which dyno machine did you use?

 

[miriguy]

fuel pump wasnt in good condition, cut at 7500rpm. using dyno jet aka happy dyno.

im only making 160whp at 0.7 bar

u can hear the sound here

YouTube - 4AGZE Supercharger SC14 loud sound


my dyno run also located under the same username

 

[synchron]

I thought supercharger rev cut is at 7600rpm. Any other modification to the engine? Like piggyback or stand alone ecu or cams.

 

[miriguy]

my rev cut is 8.5k
emanage blue, dyno tune at the same day
hks cams 264/272 8.1 lift

smoked b16a with b18c block vtec today and realised it was knocking at 6k rpm. i think due to the stock fuel pump i have changed.

miriguy,

can the blue e-manage remove yr rev cut ? I thought only the Ultimate can do that.

synchron,

I'm very keen to add in a centrifugal charger to my 3S engine coz there's no space for the roots type. You run a workshop ? My current compression is 11:1 / 11.5:1 (can't remember), can I still force induce it ? I'm actually only interested in improving the low revs.

'/s: sorry to hijack yr thread, normality 78.

 

[miriguy]

yes, only ultimate can remove. my stock ecu already cut at 8500rpm.
