all the piping for the exhaust and intercooler was done by Exhaust Technology in south australia.
I'll ask to see if he can upgrade for better horsepower.

**
i've got the forged pistons at home and waiting for the new conrods.

cams are a Stage 2 performance camshafts suitable for heavily modified turbo applications
Stage 3 camshaft apparently was for Drag Racing and idling for driving in streets not good

Has anybody got a Setup with 16psi at 300hp?
My car is doing 16psi at 258hp.

I know if I push the engine between 20psi - 25psi, then I would probably get between 300hp - 350hp.

 

I've noticed that your piping, in part, is silicone and not solid. with sections connecting between different diameters.

Thats a point to check, since under boost, the geometry of your piping is not as expected. think of your charge pipes to be inflating!

Post a pic of your engine once again, to show to the more understanding guys...

 

more boost damit.....

question's

what do you have in the following departements


1.plugs heat range

2.wastegate

3. exhaust pipe size

4. fuel system

5. bottom end

6.turbo size and make

7.cams if any

 

mad john, thanks buddy.

1.plugs heat range
ngk iridium

2.wastegate
internal actuator

3. exhaust pipe size
3inch straight through system.

4. fuel system
750cc fuel injectors, 250 litre fuel pump

5. bottom end
OEM, i've only changed he cylinder head to ported and polished STAGE 2.

6.turbo size and make
garrett gt3076r 0.64ar, boost the same as the gt28rs, but rated at 500hp

7.cams if any
Stage 2 cams suitable for heavily modified turbo applications, purchased from rpw.com.au
the durations looks same as the ones kspec is selling for $1100.

 

something is wrong on that turbo at 16psi you should be ~ 350-380 whp

the guy that runs seoulful racing hit 400 on that turbo @ 17psi... so i dunno where your goign wrong

 

he wasnt asking what brand he wanted to know what heat range plugs you are using, you should have stage 2 colder. itll help the tune since you can run leaner because it helps prevent detonation as the spark plug tip becomes less of a hot spot as they are designed to help dissapate heat from the s.p. tip.

 

aren't NGK V power two stages cooler?

 

V power means only design of the spark plug. It can be in different temp ranges.

What is part number of spark plug?

 

You sold the decompression plate so your running OEM compression right?

What is the A/F ratio you are running?

I think your tuning is hella off.

 

I've used 3 decompression plates in 8 months.
the reason, everytime I do an upgrade like, cams, cylinder head.
I need to buy a new plate.





korea,seoul
tuners and turbo installers there must be on a different level.

Goal is still 300hp, street tuned, engine idling at 1500rpm.
I saw a video of one those 500hp Hyundai and the idling and engine noises was like a Jet engine.
I don't want a Drag Racing Car and get COP{S defecting the Engine noise alone.

although it would be good to see in person the Turbo setup to compare it to my car.
