i was just wondering if anyone has anything from them or knows anything about the quality of their products.
also, what size of injectors i should get for my turbo project. i think i read that random said that 550's are too big or something, but i think from batlord's post that he needs bigger than what he has for more boost to be possible. help me out...
thanks

 

It all depends on how much Boost you want to run and what type of set-up are you planning on running.
Running 550cc injectors with stock ECU and running a S-AFC would not work properly and would start to flood at idle and run CRAPY even if you adjust your LOW MAPS to -50% on your S-AFC.
If you decide to keep your stock ECU 440cc injectors would work perfect as this is currently running on my Turbo set-up.Running 440cc injectors would be more than enough to run up to 250 WHP.
I would just go with the 440cc injectors and a S-AFC if your planning on running 6 or 7psi on STOCK compression
Hope this helps! smile.gif smile.gif

 

I know TL very well.
Because my company is technical support company for TL.
The quality of TL product are already tested in Korea market.
And My company REAL is exclusive export company of TL in world.
TL is very good skill at produc in Korea.

Originally.
TL owner was my senior in Carman park racing team 2years ago.
And he was Hyundai motor sports marketing manager 4years ago.

In case of Injector.
It depends on max boost and control type.

RD beta
1) max boost 5 psi
Fuel press max 6Kg/cm2 , stock injector OK..
Stock is 197cc ( 2.5msec, 2.5Kg/cm2)

2) max boost 10 psi
Fuel press max 6 Kg/cm2, 330cc injector OK..

3) max boost 15 psi
Fuel press max 6Kg/cm2 , 550cc injector OK..
Fuel pump change

4) max boost 30 psi
Fuel press max 8 Kg/cm2, 900cc injector
change Fuel line, 2 fuel pump

5)max boost 35 psi ( 2.6 bar)
Fuel press max 8 Kg/cm2, Duel injector
change Fuel line, Fuel delivery pipe as 2 injector hole, change intake chamber as 2 injector hole.

As I know, your car is US model.
So this ECU is Bosch M4.6 MAF type.
If you don't want to change ECU as KDM or Universal types as haltec, F-con v pro...

It is impossible to control 10 psi.
Normal MAF can't measure more than 20% air flow.
If you install AFC, it can change only 15% MAF signal.
If you change more than 15% MAF signal, check engine lamp will on.
