Hi, just a couple of general questions about the TD05 unit. What sort of boost can a TD05 hold? what is the rev range it can hold this boost?

many thanks

 

I believe this will depend on what other mods you have to compensate for the boost required.

I am running a TD05 with the standard Intercooler running 1.2bar, hopefully be increasing this to 1.3bar once the fmic goes it...

Some people running near 1.5bar, again you have to make sure the car can cope...

 

1.5bar.....1.6bar....1.7bar....1.8bar

How high do you want it?

Turbo can cope but can your internals ?

Bob..well put...

Thats that word i was looking for..internals...

 

That's not entirely accurate Bob. Every turbo has its limit.

If you want an accurate answer, you need to know which compressor your turbo's using, find the relevant compressor map, work out your volumetric efficiency at various RPMs, and plot them on the map...

 

The TD05H-16G use different compressors?

 

TD05H-16G's compressor map goes up to 2.9 bar pressure ratio. Probably with losses across the intercooler, throttle body etc, 1.8 bar would be a sensible limit. I ran mine at 1.7 bar and it was rather torquey. Your gearbox will not like it though unless STi.

1.8 bar is not sensible to hold until the red line on a 2.0. Try more like 1.2-1.3 bar with headers and good intercooling to get about 340 BHP.

 

He didn't specifically state it was a 16G. But whichever compressor he's using, it still has a surge limit and choke area...

 

A std TD05 has 16g.

Bob

 

True... but he didn't say standard either...

 

Wecome back boss

Missed the efficiency of your techspertise

it will all depend on who maps it andyf mapped mine and with an apexi pfc it used to run at 1.6bar when it was mapped on a tek3 ecu it was only mapped to 1.3bar

 

lol, well with the absense of The Oracle, thought I'd rested long enough.

 

 

 

hi,

standard td05 with 90 degree bend if it makes much difference. its fitted to a my93 wrx.

 

John, would the intercooler have to be fm to be able to run 1.2 bar? i still have slanted type, but looking at upgrading anytime now.

 

No.

 

Bob mapped my Uk car at 1.6 bar, with fmic etc. Runs very well indeed!!
