I found a good cheap boost controller for $22!!!

[XsQuiZiT]

I just received one of these last night. hooked it up to my s14 this morning, and can't seem to get it to sit at 8psi.. i'm scared that if i wind it out too far, that the bolt will fall out. does anyone else have this problem?

MM i thought the jrdsports ones were just cheap rip offs of marks ones? As in just replicas, no effort put into them just a design stolen.. Thats what i thought anyway..

Indeed. f**k this other bloke who has ripped off Mark's design, I know I'll stay a loyal customer to him - he makes an excellent product and was the original innovator!

guess you didnt read that they have a minimum of about 2psi higher than stock boost. if ur wastegate is 7psi, you wont be able to get much less than about 9psi.

Received mine today by express post.

Thanks Mark

[XsQuiZiT]

yeh, but even so, i cant get it to sit at 9psi. it jumps to atleast 10. is there such thing as being wound out too far?

[NewKleer]

if u wind it out too far you will get stock boost or boost leak/running rich/shit depending in the screw you wind out no longer seals the air

if ur getting it to 9/10 then its probably working right. do you have a fmic, and what boost source are you using? when it spikes to 10, does it then come back to 9? does it do it more in low gears than higher gears?

[Thunderbolt]

More importantly, did you remember to disconnect your standard boost solenoid? If not, then this is very important.

[XsQuiZiT]

i've got fmic.

thats how its been set up. (i know clips are on, its for illustration purposes). the red pipe goes to the fmic piping.

i'm pretty sure that it doesn't go back to 9. it'll just keep creeping up. its hit 12 before i've backed off.

[XsQuiZiT]

at the moment without the mbc, the car is hittin 5 to 5.5psi so i dont see why it can't sit at 8

[Thunderbolt]

^^^ Looks like you have it installed the wrong way around.

[NewKleer]

the boost source should be the bottom, opposite bolt. the middle one goes to wastegate

the boost source should be as close to turbo compressor outlet as possible. u might get spiking if its on the manifold side of a bit fmic

joises, that must be one good boost controller...

[NewKleer]

or a truckload of people who couldnt be bothered to read the thread when it was smaller and hence asked the same questions on every page.

Firstly I must say props to SirMark. I had my controller delivered within 3 days of the direct deposit, great service

Secondly, it works brilliantly. Boost builds beautifully and holds really well. On my RB20DET it hits 14psi at about 3500rpm, I think but it might be a bit lower. Boost tapers off to 12psi when the revs get up to 5000-5500ish but that's obviously just the turbo maxing out its efficiency.

All plumbed in nicely now, still works 100%. Amazing little controller and an absolute bargain at this price. I've since fixed all the missfire issues it caused (Note that it wasn't the controller's fault, missfires were from coils/plugs not holding up under the extra airflow from higher boost) and the car feels great.

Props to Mark for a great MBC.
