Rb20 + Dvs Jez + Td06H-20G = Winner

[Bsa]

I read it wrong sorry roy

[DVS JEZ]

Cam gears will make the difference in response.

[Bsa]

By how much? Is there much power gain? Worth doing

[raZ1911]

For the price they are yes. You can customize the setup better for response or power etc

[DaveO74]

May not be relevant but cam gears made a hell of a difference on my 25.

2835pro s all in (18psi) by 3200rpm, but I have a ff plenum etc and with the new huffer have inherited a bit of compressor surge which Jez will be working on for me in a couple of weeks.

Ok so went on the dyno last night made 242kw with major wheel spin from 5 grand on so can't get a proper reading had a extra 100kg in the boot and still spinning. There is a restriction somewhere holding it back as well will be playing today im thinking wastegate pipe so is jez so more fab needed will be opening it up to 40mm id pipe and further down the exhaust. Setup is stock rb20 with td06h running 18 pound and your usual breathing mods seeing full boost (on the road) 1st 4800 2nd 4700 3rd 4500 4th 4300 there abouts anyway didn't bother with 5th that's with mbc removed running gate pressure 10 pound spring. Now going to get a ebc and hope it rids my lag issues with a contoller. Any suggestions on why a mbc would be causing lag and please no dick answers.

[luvpsi]

So without the mbc your running 10psi full boost by 4700

[luvpsi]

Try a higher pressure spring and bleed less so get a 14psi spring bleed 4psi instead of 8psi that may help

[Bsa]

Yeah wanted to find the issue and that was it. When it was connected wasn't seeing any boost untill 5800 so I though something is seriously wrong was worried I broke something. Also forgot to mention I lost around 30kw by plumbing in the external gate. As we did a power run before touching anything is that normal?

[luvpsi]

I can't see how plumbing a gate back would make you loose 30kw but like I mentioned get a heavier spring and bleed less psi should help with the lag

[luvpsi]

Unless there is a bit turbulance happening slowing gases down but that's not enough fir 30kw

[Bsa]

Everything but that was the same bit suss

[luvpsi]

Mmm what's jez got to say about it

[Roy]

Mine lost a bit under 30rwkws when i plumbed back the gate

[zebra]

Both of you need 3 1/2" exhausts

[luvpsi]

So in other words are you saying the plumbed back gate being plumbed in is slowling exhaust gases down due to the exhaust being to small

[zebra]

in simple terms, yes

[luvpsi]

Damn I'm going to be running this setup on my 25 and I have a 3" looks like I'm upgrading to a 3.5"

[Bsa]

This is the least of my worries just pulled the intake manifold off for suspected blown gasket only to find a half empty radiator and milky brown water next up is comp test and a punch in the face by myself soon. My day just got shit I think

[zebra]

ouch, that sucks dude
