Tial 44mm EWG springs

[Evoboycorey]

After doing a little research online i have come to about 4 different conclusions of which springs are which.

I Recently purchased this item and did not receive guidelines or a colour coding sheet of which springs are which, or which is the best to run.

It will be going on a td05-16g 4g63 engine running approx 1.5 bar.

Any advice is appreciated :)

Cheers

You can double up on springs to get a higher rate. This site used to detail the combos, but i can't seem to find it. From memory, large blue and small blue was 20psi (i have this combo), but i can't run any less than 1.5BAR atm.

EDIT: Link to a complete chart for you http://www.dsmtuners.com/forums/frequently-answered-dsm-questions/246124-tial-wastegate-spring-chart-bar-psi-conversion-table.html

My recomendation: Large Blue and Small Green (around 18psi).

i am experiencing boost creep and very temperamental boost readings as i havent had a tune yet (will be getting once as soon as i can source a DJ) but some times i will pull third and it will run 1.2 then i do the same pull 1km up the road and it pulls 1.5. this makes me lean towards putting a 1.5 bar spring combo in as i dont want to run any less than 1.5. opinions?

[Oversteer]

That's a big gate and a small turbo = difficult to control !

A good ebc and manifold set-up maybe able to solve the issue, generally a good WG, turbo and manifold combo will run a few psi higher than spring pressure, ie 19psi gate spring will net ~21psi in high gears .....rule of thumb your spring should be ~ 5psi below desire boost, altho with a good manifold/wg/turbo setup running a 15psi spring and 25psi+ should not be an issue.

I`d use a 1.2-1.3bar spring combo for your desired 1.5.

Big question....what spring do you have now ? and is it wise to be belting your "un-tuned" set-up ?

[Evoboycorey]

1.5 isnt really belting it as its only pushing slightly under 300 atw. td05 16g handle upto 1.8 bar without water/meth injection or ethanol. engine good for 400 atw without any stress. it runs pretty rich from the factory judging by how much unburn fuel i get out the back on boost and the piss-poor economy i have. so i wouldnt call it belting. i havent put any spring in yet because i havent installed it, wanted to get it 100% before i fiddle around with it. i have a stainless race manifold with reinforced welds and a 2mm thicker side wall to prevent cracking. my boost controller is a blitz sbc type R dual solenoid so pretty good one. one thing i am worried about is obviously i am welding the standard internal wastegate shut. so if the boost controller isnt setup for external type, could this cause over boosting? or will it pretty much boost close to the spring combo?

[Evoboycorey]

also andrew at hyperdrive advised a 38mm was too small and may cause boost creep. i was originally looking at a 38mm but was advised to go for a 44mm

[Oversteer]

What hp is a evo td05 16g rated at ? I thought bthey were a max ~330-340hp turbo !.... thay are on subarus...e85 may extend that but.

Depends on manifold priority/wg design but a 38mm is good for a 3076+ and 44mm is good for 3582, t04z 700hp+ rated turbo....but maybe there is some good reason to go oversize on your rig.

[Evoboycorey]

thats about right they are rated to that. having a custom flange made up with wastegate and screamer mounted straight after the exhaust mani. that seems to be the way everyone else does it
