How do you figure this? I highly recommend using VTA, through all the testing I have done it has proven to be the most efficient and manageable way of dealing with surplus charge air. However it must be setup to suit your car, if you just slap on any old VTA you are asking for issues.

I figure it because you said this:

Yes seriously, it's an important part of my current setup and also on tens of other cars I have setup. It took a few years of R+D to get it right but everyone running my setup is happy with it, I am just curious as to why VTA is hated so much.
And with many members on here, THAT'S exactly what they want to hear, they will read no further and away they go.........

I'm all for telling folk stuff, but please be careful to give ALL info in your post, so as not to simply give those who don't know enough the "ammo" to do as they please...with possible consequences.

Regards, Jeff.

Still don't see where I have suggested not to fit a VTA?

Besides this you can't take control or responsibility for the actions of others, if they choose to make uninformed decisions and modify their cars with ultimately detrimental effects to their engine then that's their fault not yours.

It's not the 'ammo' or the 'weapon' that is dangerous, it's the person with the finger on the trigger.

You misunderstandf me Ian, I'm saying your original two posts COULD lead those who don't know, to think that yes, it's OK to slap a VTA d/v on their cars, despite much advice to the contrary.

And I have to take exception to the second sentence: anyone giving advice has a RESPONSIBILITY to ensure that their advice is either unambiguous, or gives both sides of the argument, so as NOT to lead folk into uninformed decisions.

Take exception all you want

I disagree entirely so long as you are not deliberately misleading people, anyone could go into great detail explaining exactly what they are on about and you will still have ambiguity and uninformed decisions taking place.

It's down to the individual to research and obtain their own information, more importantly it's their choice to act on that information.

I have made it very clear from the beginning that if you are fitting a VTA it needs to be setup to your car. Can't make it any more clear cut than that.

Cheers Iain

Well, yes, but I was trying to make a point with a guy who has been shown to be a know-all on here before.

Remember his insistance that his turbo mod produced un-dreamed of power? And Harvey showing it to be rubbish and uninformed semi-knowledge?

Seems he hasn't changed much

I see the usual suspects are on here slagging off someone who wants a dump valve.

Now not so long ago a chap came on here because he had just bought a Scoob fitted with an after market dump valve and he got rid of it and replaced with standard.

And do you know what? Not one of the usual suspects offered advice

Is it me being the know it all?

You or Harvey (RIP) showed me nothing before, I stood my ground throughout, read the thread if you can't remember.

It indeed seems like nothing has changed, scoobynet is still full of narrow minded arrogant people like you.

Just so we are clear, your statement accusing me of being 'a know it all' is more personal than on topic.

Regardless of what the power output I achieved from the VF35 on my V3 Sti the overall setup was excellent and it could run 11.8 @ 111mph at santapod, this overall setup included my VTA setup so I must have got something right, not to mention the 400bhp VF43 2.5 hawk and 380bhp VF43 2.0 Blob (all on V-Power and different mappers) I have recently setup but I suppose everything I touch will be false

Know it all indeed.

Mate, get real.

You came on here once before, telling people who knew better, what you knew, (which wasn't much, since you failed to understand even how a rolling road was calibrated, let alone the finer points), then ran off with your tail between your legs.

If I were you I'd go wherever you went again.......

The operative word I'm trying to get you to understand is RESPONSIBILITY.

If you give advice, you have a RESPONIBILITY to EITHER be correct, or to give both sides of any argument, so as to allow people to make an informed decision.

You didn't do it last time, being more interested in showing off than being responsible, and you have shown this time that, once again, you are more interested in showing off than being responsible. In your own words.

I shall not bother arguing with you any more.

You are what you are. You seem unable to change. If you think that's personal, get over it.

I've retired now from giving advice and having a bit of a laugh
No saving the youngests and unguided nowadays

If they want to go pppppppsssssssssstttttttttt
That's they choice
One day they might realise that people just laugh at them

The more scoobies that get modded and them end up on eBay for a few hundred and scrapped and parts taken off the better it is For the real enthusiast as they cars will become rarer

Run the forge on my hawk and on the missus '99 sti without any issues at all.... Obviously as stated tho it would be advised to get your system set up right with it.


On another note (which might cause some discussion) if the MAF senses what air flow is going into the engine at any giving point and that a VTA will disturb this process then surely just letting off and shutting the throttle body when changing gear does exactly the same thing and reduces the air flow into the engine? Something the MAF wouldn't compensate for???
Or is there something built in within the system that tells the ecu that when the throttle body is shut by 'x' amount then that will reduce the reading from the MAF by 'z' amount???

Whatever I just like the noise of it myself, pssssttttt... Instant grin factor.... And as stated if set up correctly with the front mount there's also a great flutter at lower revs

Brining up the past and twisting the truth as always, implying that as I don't know how a rolling road works I am some how stupid, 13 years as an aircraft engineer specialising in engines, fuel systems and air to air refuelling systems I would argue I am far from stupid or am I just showing off????

Again you are implying that I am stupid and don't understand what responsibility is, yet part of my job is to ensure that aircraft are in a fit state to fly, quite a responsibility I thought, or am I just showing off again???

Here you imply that I am indeed not correct in what I say, as both sides of the argument have always been clearly available throughout this thread.

Find me where I have said that I am more interested in showing off? I did say that we cannot take responsibility for others actions that is correct.

I am confident that any information I have given is 100% correct.

Your entire statement above is personal?

I still have no idea how a rolling road works and have little interest in it, however I do have a great understanding of what responsibility is, I also understand from how you are behaving towards me now and previously that you are what I would loosely describe as a 'crap human'

Who are you to pass judgement on me?

You are more interested in dismissing me and putting me down much in the same way you did before, I didn't run away, I didn't have my tail between my legs, infact I stood my ground the entire time as I will do now.

As for showing off, is it not just natural to backup statements with facts and figures proving what I have done when I am confronted with someone like yourself who is fully focused on making me look like a fool, which I hasten to add I have never done to you, so why you feel this personal attack is necessary is well beyond me.

I suggest you grow up, or at the very least give me the benefit of the doubt instead of being a narrow minded keyboard warrior.

Cheers Iain.

Alcazar, may i suggest you read this:

http://en.wikipedia.org/wiki/Ad_hominem
Your arguments against Iain are clearly an ad hominem and as such are an informal fallacy. A flaw in reasoning that renders the conclusion unpersuasive.

In other words, you are talking out your ****.

iv caped mine off...dont run a valve at all..and the car runs smooth with no dodgy running.

i ran the same with my evo for 7yrs and that was running a high spec.

plus you get turbo chatter through the induction...which i think sounds more rally car than a dumpvalve lol

im not saying its the right thing or you should..just that i have

If running dump valve'less is good enough for a WRC car then its good enough for me. If they could of improved performance by having a VTA then im sure they would have.

I ran my 400+ classic with no dump valve for over 2 years up until I sold it. Car ran perfectly and performed no different to when it had a dump valve.
