the cold water should flow through the CC in the opposite direction to the air charge

Okay thanks, that's what I thought, so the water flows from top to bottom (after being cooled in the rad) and the air travels from the bottom to top. 

[siztenboots]

yup

[Andy_VX]

Going to buy some coolant for the engine and cc systems today. Does anyone know the PA CC capacity and the recommended mixture ratio?

[Andy_VX]

Made lots of progress this weekend, chuffed with the results! 

 

Having installed the radiators it was time to run the pipework down the sill, having read the guide i thought this was going to be a nightmare but thanks to my freakishly long arms it was probably the easiest job so far! I literally put my arm down the sill from the rear, got hold of the foam and pulled it out. Removed the plastic trim from the interior, poked my arm through the hole and managed to push that front bit of foam to the side, couldn't quite believe my luck! Poked the hoses through and pulled them out from the other end, literally took me about 10 mins so i was relieved! 

 

 

 

 

PS. I know it's not ideal having the hoses tie wrapped together but that will keep it tidy until I find a suitable clip. 

 

Wanted a nice easy job next so I replaced the rear discs with the fronts as they weren't that old and replaced the fronts with new discs. Cleaned up the hubs and applied copper grease too. 

 

 

 

Next task was mounting the heat exchanger, I knew this was going to be tricky but it was made a whole lot more difficult thanks to a snapped captive bolt that supports the bottom of the heat exchanger. Thought about trying to remove it but access would've been a nightmare and I would have had to cut a new thread so I decided to make my own bracket utilising the top support.

 

Nightmare!

 

 

 

 

 

Once it was in place and properly mounted it was clear this was a much better solution as the bracket added support.

 

I connected the air hoses and started it up for the first time tonight. I disconnected the coil pack and turned it over a few times to prime the oil around the new turbo, checked the oil lever which had dropped a little so I topped it up, plugged the coil back in and it fired into life. Ran like a pig for a while so I turned it off removed fuse 8 and left it for a while, ran it again and it did run a bit better but it's obviously struggling to adjust with no AFM. Once it had warmed up and stopped smoking I gave it a rev and it sounds crazy, lots and pops and bangs and loads of boost noise. I did notice the silicone pipe that runs from the CC - Top hat appeared to be collapsing slightly so I will replace this with a solid pipe to be safe. 

 

Just a few finishing touches now and then it'll be time to put everything back together. Really excited to get it mapped now!

If your going stage 4 and tracking with track pads you will be wanting better discs (wider, such as ep bells)

[Andy_VX]

I had these discs going spare so thought i'd fit them for now, to be honest they've been pretty good in the past albeit with 50 less BHP... I'll be fitting ducts in the next few days so that should help with cooling. 

 

Going to see how everything performs on the road before tracking with stage 4.

 

Will probably go to bells with 4 pots in the future when funds allow.

Wicked, you will love it, its overkill for the road but overtaking is a blast.

 

Track is great fun, just re learning to drive it is the key.

 

So much more fun doing the fitting yourself, really get to know the car inside and out 

 

Good work 

[Andy_VX]

I've never been in a stage 4, it's probably a bit mad for the road but it's just a toy now and I've got to at least try and keep up with my brothers Griff.

 

I've really enjoyed doing it, took my time and made sure everything was spot on before moving onto the next job, gives you real piece of mind knowing it's been done right. It's taken me a lot longer than a specialist but I've saved myself a small fortune in the process.

 

I'm a bit nervous about getting to grips with it's performance but the original map was never much good so I think a smoother, more linear power delivery will actually make it easier to drive despite the extra power. That's my logic anyway...

Who will you be getting to map it Andy? If it's CS don't expect it to be too drivable. Having had 3 of their maps, I'd strongly recommend another route, possibly with a 3rd party ECU if you could stretch to the cost. It makes the biggest difference in power delivery, and I retrospectively regretted putting off this step for 2 years.

No not using CS, having spoken to Alex and reading lots of reviews I've decided to get it mapped at Rabbid rempas in Basingstoke. Richard has lots of experience with both the Z20LET and LEH so it should be in good hands, we've spoken about what I want from the car and he seems confident he can achieve it, will likely spend a day there fine tuning it until i'm happy. I'm not chasing crazy figures, just want a nice drivable car that will run at sensible temps. 

 

Which ECU are you using Nev?  My Dad has the Emerald ECU in his Escort and that seems very good, almost endless tuning options.  

[scw02102]

rabbid (Rich) has done my last 3 remaps and many other VXers on here all pleased and he defo know his stuff

 

mines stage 4 and not stupid aggressive, its down the to mapping

 

he has done loads Corsa and Astra#s running 500bhp at the front wheels, but still makes it driveabe by the power delivery and torque

Good to hear from another satisfied customer, very excited to get it mapped now!  ​ 

[scw02102]

Dave and Adam have both had their cars done there and both extremely pleased

[siztenboots]

Rabbid , have they even driven a VX220 on track, driveability and intake temperatures isn't something you can do on a dyno.

 

If they don't own one, then are they using customer cars for development and testing , sounds like just generic maps from a Zafira gsi.

 

Someone post up the graphs

D-Dubs should have all his graphs, he keeps everything lol

So purely because a mapper doesn't own a VX220, they use "generic maps from a Zafira gsi" as you always claim?

 

Lol...

 

Keep up the good work Andy, build looks sweet.

If you open up the ecu file , you can see all the torque limiters and reserves for auto gearbox , power steering , aircon.

 

If the engine response exceeds the torque ramp rate ( and on a lightweight VX versus a Zafira it will ) , then the ECU will intervene and you will get torque interventions which ruin the driveability and throttle response.

Met with Dave on Saturday and went through what he was given, but the graphs were missing fuelling and boost. No before/after comparison so not possible to validate the claims.

Right... but where does Rabbid state he uses Zafira GSI maps on a VX220? Or any other mapper for that matter? Rabbid is one of the most well known Vauxhall mappers and has mapped plenty of VX's.

I'm just unsure where the assumption comes from that every other mapper seems to be using a Zafira GSI map...
