my five.

[James5]

Engine back in again , but rain stopped play before I could refit everything.
Also bought a VNT ..

Andy, you will love the VNT once you have it setup to how you want it, boost like a T2 yet the pull of a T3 you will run out of rev's before the VNT stops pulling aswell even with a cam

hi guys what car do you get a vnt from i know the vag use them is there one in particular that you use ? cheers rob

The one Andy has is custom made as was mine by Turbo development's a few peeps have made them themselves including me from other car's but it takes knowledge, skills and the tools to do it correctly.

[DeanGT5]

out of those 3 I have tools  :lol: maybe not the right tools though  :wink:

This is at 11psi ( first time ! ) boost.

Can I ask you a few questions ?

How do I run more boost ? I have a bleed valve , but I would rather control via actuator. Can of lengthening rod rather than shortening it ?
Can I get the boost to come in lower ? I want popeye forarms from torquesteer!

I seem to have a small leak , like an exhaust leak between the core and the rear housing. Any ideas ?
VNT's are awesome matey best turbo for a 5, glad you like matey you will never go back to a normal turbo now

You can make the boost come in early by undoing the bolt and undo the little hex head grub screw that the actuator arm sit's on this will bring boost in earlier  but you will need to shoten the actuator rod also this could be were thing's all go wrong, personally leave it as it is turn the boost up to say 20 to say 25psi and you will be wheel spinning from the off.

However , I am getting only 1/2 psi +ive pressure until 4000rpm where it climbs to full 18psi.

What am I doing wrong ? Dont get me wrong , its fast , very fast. But its a t28 style delivery.

If I plant my foot at 3000rpm in any gear I just get the +ive 1 to 2 psi of pressure until those magic 4000rpm and then we are off like a scalded cat !

It shouldn't be T28 delivery it should be 500rpm max between no boost and full boost although it maybe laggier in higher gears
ref what is happening did it do this with the 11psi it ran before or is this only as boost has been upped with bleed valve.

[andybond]

I have the five now boosting at 2500rpm and coming on boost hard.

I also like a spaz managed to hit 28psi. It flew.

For 8 seconds , and I shat me pants and pulled into a bus layby and turned the wick right down !

18 slightly spikey psi later and wheelspin in first is rampant ..
