gate spring identification

[202mphbusa]

Having a very hard time with identifiing the bag of springs that came with my Tial MVR 44mm gate
Yellow spring that is currently in the bike nets me ~5psi
I have also
short green
long small red
medium white
and two large uncolored one med and one large diameters
All the spring charts I find for the tial stuff doesn't show a yellow and ~5psi

Blue spring was on my lap while typing and sorting haha

 

[greg3852]

Call them. No?

 

[202mphbusa]

HAHAHA way too much work.
Not a big deal, just thinking that Loring it would be nice to have LESS boost in first gear

WHAT THE F did I just say ?!?!?! "LESS BOOST?"
can I take that back

 

[202mphbusa]

So I pulled my wastegate and started checking the springs with shop air

Green .3 Bar (~4.5)
Red .4 Bar
Yellow .5 Bar
White .5
Black .6

That's it for now I wanted to figure out a lower one
I am leaving the yellow out and leaving in the green .4
So hopefully Loring first second gear will not be a poop show

Closest I can find to what I could measure, Do I measure when the gate starts to lift? or tops out?

Jay M from Real Street talks about it as crack pressure, when the gate starts to open. He also shows how he tests it in this video.

Are you running any kind of boost controller, or just wastegate spring pressure?

 

[13B-RX3]

I may be wrong, but I would assume: Black/Blue/Yellow = 17.40, Black/Blue = 11.60. The yellow would be adding 5.8 PSI. Maybe they don't recommend just running a small diameter spring by itself?

I have run just yellow for about four years
there are 4 different diameter springs you can stack inside

I have a AMS1000
The "problem" is at Loring just the yellow spring is enough to over power the tire in first and second

That said I run higher pressure in my rear than some
and maybe I should start to look at rear tire warmers

That sounds like a good (fun) problem to have! Do you have any idea how much boost it's actually making in the lower gears? If you're not able to get it close to spring pressure, you might have a bit of a header design problem. I don't have any experience with the increase/decrease style boost solenoid. I've always controlled boost with the ECM using a 4 port solenoid and had great success.

If you have an air supply for your air shifter, could you use it with the AMS, instead of manifold pressure?

Yellow spring that has been in the bike since I got this gate generates ~4.8-5.1 PSI , spring is .4 bar ~5.88
No gate spring gets as low as 1.5 PSI ish

AMS1000 I use air off the Swingarm, I found using plenum pressure made the gate a bit lazier

Damn, you though of everything! Only thig left is to hold the BOV open LOL

If long ago I had thought of everything I would not be Sending my backup Megasquirt ECU out for a second set of injector feeds

WHHHEEEEE MORE BOOST

why is one set of injectors not enough? people here run over 2000cc injectors just 4? im running 4 x 1300cc injectors in mine.

I have four 1000's
Even if I go with the 1300's that is enough fuel for just under what the turbo can do, with little or no buffer

Ah okay, i didn't know how much boost you are aiming for, i know when I was running 20psi boost, with base fuel pressure at 43.5psi my 1000cc bosch ev14 injectors ran at about 90% duty.

There are also other tricks like running higher base fuel pressure.

plan eventually is ALL the boost and Nitrous
