What's the biggest problem when one goes bang, bar from waiting for it to be repaired. Will "They" believe it was and is standard

"They" IM's veiwpiont(and would also like us all to think) is in the majority of cases the leaning out is due to "US" modding, Blame fitment of back/box, I do agree with a possibility of induction kits doing it. Consenous is "they" believe there were kits on, but removed after the bang.

Another problem is that 'Most' of the Blow ups happen to us poor sods on the road so no proof we didn't, put wrong fuel, fitted B/Box, Dump Valve, Induction kit or Non OEM cupholder. "They" would love to blame "US" all for there cr4p parts IMHO


Well one Friday January, Prodrive were testing a mates STi7 PPP at near Flat out in 5th it let go and went bang 3 very small melted pistons. So with a test driver, in a controlled enviroment, with , correct fuel, absolutely no mods, valves, filters or B/box. Also the "holy graille" a laptop connected.

So lets cut all the Bullsh*t out, What leaned it out?

I have no Idea if the laptop was Delta Dash or how much info was being Logged. I am not going to divulge the owners name, I knew this info on that Friday night(5 ish weeks ago), I have not been asked not to post this on Scoobynet but I felt it inappropriate to do so. But I would be really P'd off if lost my warranty because of a B/Box and was really the cars fault.

Tony, was this an STi7 PPP with a piggy back boost clamp? Just trying to clarify what we are talking about.

Also, how does this test coincide date wise with the release of the uprated fuel pump as part of the STi8 PPP kit?

John,

Yes the only STi7 PPP is of piggyback type

Sorry The fuel Pump issue wasn't the piont I was raising

For God's sake guys, Imprezas have been going bang since day one. Other cars do, too. Give Prodrive and the PPP a break, will you

Tony, your mates car will be fully warranted, so what's the problem.

It could have got a bad batch of petrol. That's not Prodrive's fault. For all they know (in theory, i'm not sayin this is the case with your mate) someone could have had a full decat on their car prior to the PPP being fitted, or an induction kit, or whatever.

You can't just say "it blew up on Prodrive's track so there's a fault with the PPP". And if there were, and it were otherwise standard, IT WOULD BE FIXED UNDER WARRANTY!

I thought the point of the post was not that is was anything to do with Prodrive, but there was one of the 'bangs', under controlled conditions, with a laptop connected, so there's a good chance of being able to tell, or at least narrow down, the possible causes?

nom > that is the view I am getting as well.

john banks

Get a knocklink guys (surely that won't void warranty if it is just a gauge with its own sensor and powered off 12V). It is unlikely to just go bang after a single episode of det, but is more likely to be detting its knackers off for weeks you just can't hear it.

nom

But why didn't they spot that with the laptop plugged in? Or maybe they did & it isnt being described, & I suppose even more so it could have been running perfectly with the laptop plugged in but has been 'detting its knackers off' for the past 2 months, weakening the components & they just happened to go when Prodrive was playing. That one seems the most likely to me, laptop showing det or not...

Nom & Christian,
Yes that was the piont of the Post. The Laptop may not have been set up to record all possible DATA coming from ECU

Dave,
Agreed It's warranteed. But the dreaded finger pionts at "US" for fitting a Back Box ;( Engine reliabily for Std and PPP'd Scoobs is Very good
But Engine can't cope with a change of B/Box someone give us owners a break. Bet during your trials saw boost spikes changing one Performance B/Box to another( with all other components STD

Edited to say I never, ever BLAMED Prodrive or PPP just there unfortunate luck it happen to them. but may hold some answers once the data is sorted.

John,
Agree with Knock link

Tony

Tony I am with you m8.

I have just bought a STi 8 and a 03 WRX, called the dealer and said I would like to change the BB on both cars, his reply was not a problem we have WR Prodrive BB. I say well I would like to fit a BB that I can hear no point spending £350 x 2 if I can't hear the bloody thing, he then says he will have to speak to the mechanics.

To put this into perspective, when we bought our last new scoob (MY00) from another dealer they even fitted a full magnex on the car and had no problem, actually said what a great exhaust the quality of the fit was like standard!!!

So come on, don't tell me a BB is going to void warranty, other car makers would only void a warranty on the components affected i.e. the exhaust. How many un modded scoobs are there, reality check time I think

Bob Rawle

Having a laptop plugged in would not be likely to highlight this sort of thing, the ecu can ignore things it should not and react to things it should not, the STi UK (I assume) has the same ecu archetecture as the JDM car and that reacts well to det related issues ... however it won't do a thing if inferior/poor oil is used and the oil film breaks down .. and if so then its down to the owner/dealer servicing not prodrive at all. These cars run so rich its never going to be affected by a backbox ... fact !! The only other thing's that could come into play is if it hydrauliced itself, or if the fuel pump decided to take a break and it suddenly went mega lean in which case no laptop would have saved it.

Its a sad fact that these engines do have problems from time to time.

I posted this on here

Without wanting to put the cat among the pigeons, as they say, I have just had the PPP kit fitted to my STi7, last week, and it had a 'performance fuel pump' fitted as part of the kit.
Part Number 44S/T5/001 in 'performance by Prodrive' box.

I know exactly what is fitted to my car, no guesswork, no opinion, just FACT.

I have got my old pump in the new Prodrive box.

The high performance pump is encased in a black foam rubber sound insulating material. The std pump does not have the foam covering, so its easy to tell them apart.

Could this be the 'fix' people are suggesting needs to take place,
taking place?

Edited after reading Dave T-S;s comments on here
http://www.scoobynet.co.uk/bbs/threa...=170888&Page=7, regrading ECUtek flash remaps and uprated pumps on later STi7 PPP kits, in lieu of piggyback boards on the ECU and std fuel pump.
Perhaps thats what's fitted on mine?

I should have mentioned also, that the ECU has a warning label on it stating 'THIS ECU MUST ONLY BE USED WITH A HIGH PERFORMANCE FUEL PUMP'.
So whoever manufactures/reprogrammed my ECU is quite clear about what is needed for safe running.

Cheers MTR

Just to let you know another STI blew up in France yesterday...

mutant_matt

Claudius,

I don't suppose you know if the Subaru France (etc.) know about the fuel pump issues do you and if they have spoken to Fuji? Having said that, I think the official line all the way from Fuji down is that the OE pump is good enough for a standard car....(which I don't think everyone here agrees with...)

Matt.

Claudius

No, sorry, no idea how Subaru France communicate with the HQ. All I know is that everybody hates Subaru France: slow, inefficient, expensive, dont know jack, no tuning parts, etc. That's what people tell me and what I read on French language web sites anyway.
