I'm loathe to take part in this thread, but if you're concerned about low boost then have you still got your original intake pipe? Also check boost control solenoid(s).

 

And, I'm a little surprised I'm saying this, but... USE THE SEARCH FUNCTION (or at least try to FFS)

 

 

THEN DON'T! I'm just asking the advice of fellow vx220 owners. Sorry but I thought that is what Forums were good for? I dont expect people that dont want to help to help. Just those that are willing to.

 

 

Fcuk it, time to get the sand out...

 

If you read my comment(s) I have helped. Or at least tried.

 

I've suggested that if you are concerned about missing boost, which you indicated you were/are, then a good place to start checking is your intake pipe. It's a common problem, and one myself and others have suffered from. Same goes for the boost control solenoids, another common problem worth checking. but if you don't want the advice, then that's your choice.

 

Also, suggesting using the search function is helpful too. It can lead you to the answer you need much quicker than five pages of conjecture and varying answers. We're at six pages on this thread already (I've seen complete project threads shorter) and it still doesn't feel like you have the answer(s) you want to - though it also feels like your aims and objectives are changing as much as Techie swaps exhausts.

 

But if you don't want that help, then fine. I'm back off to work, though I might create a 'Slindborg' list first...

And you have missed Graeme's question. Yes he started by saying I am loathe... But read the immediate point thereafter. But take his final point and consider it... Let's not kid ourselves here, yes you are asking some pretty relevent questions, however you have to understand that these topics have been done to death on here. The use the search function comments are because there is far more to be gained by researching through previous threads than asking for a synopsis in a single post. Also... Your attitude regarding 'it should be able to...' is what will get goats. If it was that simple it would have been done before now by everyone on here. 260bhp vs 240bhp - on the road are you really going to notice??? I had a 145bhp NA and that was more than enough for anyone on the road. Numbers are for the pub, ability to make the most of what you have maketh the man.

[PaulCP]

They also said the Milltek was not able to flow over 240bhp without restricting power!

  The Milltek with std manifold on an NA/ Scharged is approaching its limit at 240, although some have managed a little more hence why I say approaching.

290 on miltek possible, holds back about 10bhp over 3 inch systems Sounds like intake pipe and software all thats needed but clutch on its limit of torque Beyond this is time to spend some cash I am afraid DG

[Nev]

My car made 293 BHP (on the old CS dyno) with a Miltek exhaust many moons ago.

[Duncan VXR]

Meant to say becomes a restriction from 290 but can still make more DG

[P11 COV]

OK , called Thorney and CS. Both say that 260 is not possible.

So thats the first kick in the nads.

 

My Car specs

VXT

Milltek

De-Cat pipe (Thorney)

Upgraded Turbo Downpipe (Thorney)

ITG Filter in Modified Airbox

Iridium VXR spark plugs

 

Thorney are saying around 230BHP and CS around 230 and 240 if lucky!!! This seems a bit rubbish given that on std boost with std exhaust, std filter, std plugs, std airbox it can do 200ish with a Vauxhall warranty and expected to cover mileage of over 100,000 running that low unstressed set up. With most turbo cars more boost/fuel make 50 bhp extra with no other mods. (Subaru, Evo, Cosworth, VXR astra etc etc...) My Stage 1 Map shows 233BHP so if I go to stage 2 I might be "Lucky" to make an extra 7BHP or possibly loose 3BHP??? £1000 exhaust, £220 decat pipe and £250 Turbo pipe, Airbox mod that everyone raves about and CS recommend at stg2 and Labour all for -3 to 7bhp?? Not to mention the £500 to map it!!

I thought from what everyone was saying that stage 2 should be around 250BHP (and I could ask for more if I wanted to risk clutch/overheating on track, which I didnt want)

 

Any thoughts on stage 2 at 230bhp??

 

 

Did they not mention charge coolers? The difference between a lot of those car you mention is that the VX is a mid engined and therefore harder to cool. Above 240/50 most people believe it is necessary to fit a charge cooler or bigger intercooler. If the intake temps get too high the ECU will back the power off anyway. Maybe this is what CS were getting at.

I am not 'concerned about boost, and I never said I was. I was asking what boost is normal for 220bhp and quoting my boost figures. Simple as that. I know I can search and I do/have done. Thanks for all your help and ill shut up now as I didnt know there was a page limit to asking for help, sorry. I thought it would stop when people got bored of helping me out, lol.

Oh, my remap at Courtneys is Friday, so I may be able to make Sunday though I think the wife may say no to 3 days in a row playing with cars!

If you can't or won't accept help from the likes of Graeme (who really is someone worth listening to), why should anyone want to contribute? We have suffered egos far too many times on here... I am not normally one to say boo to a goose, but your attitude has ruffled my feathers.

I so so so so sooooo want to add one to the list, but at the same time its as funny as an astravxr thread

[Graeme Lambert]

Bugger, forgot I'm going to NEC Classic car show Saturday so wont be able to make it. Found a graph on-line and mine looks way down on boost compared to 240 bhp car.

Oh, my mistake.

 

Could've sworn you said you thought yours was 'down on boost' compared to a 240bhp car. You say you are at 233bhp, which in chooner terms isn't far off 240bhp - certainly not in terms of boost levels. I would suggest you check your boost solenoids, as that may actually give you some more power (maybe even 7bhp) without a remap, but for some reason that suggestion didn't go down well last time so I'll refrain. Still, a remaps only £500 or whatever. What've you got lose?

 

Definitely sounded to me like you're down on boost. Way down in fact.

 

Please start a list and add me to it, as for some reason you've made me really really sandy ...

[slindborg]

Just to add to the fun, boost is not equal to power, its merely a measure of how restrictive the intake is

12 pages of sandy goodness.

[vx220Tim]

What has Ego's got to do with anything Mangham that I have asked? Odd response to someone asking about best way forward with my car. After all I have not said I want a million BHP just 250-260. Not Ego based I'd like to think.

 

Yes charge cooler has been mentioned but I am not after that much power. I would like 240-250 and dont think I should need a charge cooler for that. 

 

I am very happy to take advice Graeme but swearing at me in your comment and use of bold letters, seemed rude and a little uncalled for to me. As that is not how I would talk to anyone who was asking advice on a forum.

 

The car pulls well with this 'low' boost as proven by the times of the vbox so maybe a good map? As anyone can get power by just adding lots of boost. The graphs are smooth for AFR, torque is flat and power is smooth up to the 217 bhp it is currently running. (Initial dyno from Thorney said 195 pre map and 233 after stage 1 map) so optimistic I think!

 

Ps as for this list, is it a list of great forum threads that have been started by big ego'd,  hyper intelligent people like myself   And this sandy issue worries me. I always have a shower if I get sandy, I suggest you do the same!

[slindborg]

a charge cooler (or bigger air to air cooler if you get sold that idea) is more than just getting POWAAAAHHHHHH, its about keeping the power that you have.

 

On a nice cold day like friday will be, you will probably get 250ish, then go and drive that hard (track or road) on a nice warm day and you will find its a bit slower as the software will be doing its best to protect the engine (thats good by the way!) and pulling timing or adding more fuel if it can to keep things cool, as such you will lose power.

 

some mods do give you extra power, some let you keep what you have.

[PaulCP]

There has been much debate on the charge cooler vs inter cooler over the years with the conclusion being that the charge cooler is the way to go, really for the reasons outlined by Slindy. Heat soak is a very real issue with these cars. Unfortunately the TMS approach to remapping and upgrading Turbos does not have the best reputation on here (I think that this is the nicest way I can say it)
