safe boost pressure after blowing engine!!!!

[RT MECHANICS]

[QUOTE=Justin;197202]Cragmaz,

Secondly, according to Paul the car has been looked after and heavily modded by RT mechanics for the last 4 years, so in all honesty i would find it hard to believe that the map (running that boost etc) would take 4 years to blow an engine.

Hi Justin

Just to make it very clear as i don't want any incorrect info about me is i have done NO engine tuning at all on Pauls old car i have only fitted S uspension/brakes etc to the car we do not do custom maps at all on volvo software

Hi Russ,

Thanks for that. I wasn't saying you had btw

[cragmaz]

it seems i may have upset a couple of people with regards to my comments about my car, and to those involved, i appologise, i was very angry and deeply p****d off with regards to my car, i never intended to upset people, so i am very sorry if i did.
I suppose i am just as much to blame for driving it hard, but dint expect it to run as much boost with no limit.


Anyway thats done now and I get the car back this week with a bit of luck, and am going to have to investigate a number of things to make sure this never happens again, it will be running a standard T5 ECU for now, i am thinking i will have to put on a standard volvo boost control solenoid,but not sure! and poss a set of white injectors, so its got a long way to go, but i would rather have a safe reliable car!,
Can anyone advise with the above suggestions please, and again to those upset by my comments, i am very sorry, was just well f****d off with this happening after just 3 days of ownership!!!

Best Regards
Craig

hi i would either put white injectors or green ones on also i think when running the 19t the standard volvo 850 bcs doesnt like it so many people fit a mbc also when you change the injectors you will probley will need to get another map i would most likley have the psi set between 15 - 16 psi with the standard internals if you have stronger ones i would only take it to a max of 20psi its better to be safe and realible than sorry also if you do have standard internals i would be very carefull and low speeds in high gears i forgot to ask what gear and speed were you in on the motorway when the bottom let go?

I don't think you have anything to apologise for Craig! .. the only issue that ever crops up when a post like this appears is that people start making accusations or innuendos/assumptions without knowing all of the facts and start jumping to conclusions or starting rumours of another VPC conspiracy or cover up etc. A certain alternative Volvo forum thrives on threads like this and a quick scan over their confirms that they haven't failed with this opportunity either! lol!

Regardless, I hope you get it sorted and up and running safely!! - and definately invest in an AFR and maybe an EGT gauge if you get the chance or are planning on modding it to it's former levels!

[Justin]

Good luck with the project, as pangster said, it wasnt down to you.

[irf]

i don't think anyone could fail to be peed off!

won't comment on the whole T5D5 v VPCUK thing.

i wouldn't put greens in as afaik if the map isn't written specifically for greens it will throw an engine light on and will go in limp home mode.

i have white injectors with an 18T but i'd be inclined to go with blues on a 19T. either will probably be fine, oranges are a no no.

you could just chuck in a set of whites or blues and it may be fine, it might not. i would strongly urge you to at the very least, get the car on any dyno that can read your AFRs and go from there.

with the standard ecu i would personally let the ecu and the bcs control the boost rather then going for 15psi. better a slow car(comparitively) then a blown one.

best of luck, what a sad introduction to the volvo world.

yes my fault i do get the green and blue injectors mixed up and yes i wouldnt put the greens in but would use the blues with the 19t what i was saying with regards to the 15- 16psi is the most i would go to with standard internals as you said better a slow car (comparitvely) than a blown one

Pete, whats an "mbc" you speak about, soz to be a dummy!!!

manual boost controller...

[t5 pete]

its a manual boost controll if you decide to fit it i would have the car on the rollers or have the map and rollers to see if your afr's are ok all it does it increase the boost pressure to what you want but doesnt change the fueling so if fitted i would get a custom map to accompany it and make sure the afr's are correct

[cragmaz]

oh, also guys, can i get hold of a set of white/blue injectors easily, and an estimate of cost would be good if anybody knows please.

whats the diff between the white/blues, and how easy are they to fit??

To be honest, i am a bit surprised the previous owner dint uprate them when he fit the 19T

[t5 pete]

i know hlm can supply new or reconn there easiy enought to fit all they do is allow better flow the white and blue injectors seem to be the favourate choice for the 19t but if you fit them please make sure you get the afr's cheacked of fit a afr monitor

I think the whites are 350 CC and the blues are 395 CC but you need the ones that your map has been written for..

from what I've read you want to match your injectors for your mapped power levels and ideally aim to keep injector duty cycles below 80-85%..

[volvolised]

The whites are fine with the 19T bearing in mind you will never run it at full potential if you've not had the rods don..i.e WOT at low revs high gear...if rods are done and you have acceptable injectors, greens, you need a proper custom map from ???........(lets let pangster tell us)..mbc is a bad idea unles you've afr and accurate boost gauge and basicaly know what you're doing..

[siamblue]

I would just like to point out that this car was Paul's wifes daily drive, As i have seen it nearly everyday for the past 4 plus years, plus Paul looked after this car and never used the full power in anger,

I think I've already answered that warren?:

MTE's not the only option as far as mapping goes to be fair and it would depend on what you want from the car and where you live/how far you're willing to travel and your overall goals/aims with the car as well as what resources you have available to you fairly locally? and of course how much you want to spend.

As far as getting custom mapped in future goes that will depend entirely on when the mapper is in the country and whether he/you are prepared to travel (as yours is an 850 you cannot take advantage of the MTE softloader - which seems like a fairly decent bit of kit and allows for remote mapping/data logging which overcomes this restriction on ME7 cars).

Have a think about what you want - i.e. a remap (MTE etc) or an ECU replacement (piggyback or standalone) as there are quite a few options available for these as well and speak to tuners directly regarding what they can do for you in terms of your goals/aims. The bottom line regardless of what option you go for is that ultimately your car will only perform as well as the map that's written for it - as you've already found out.

I would also invest in an Innovate or AEM wideband AFR gauge to monitor things once its mapped!

Good luck with it all!

For me (personally) if I was going down the custom mapping/tuning route then I would probably look into getting a Dastek Unichip mapped by Gerry Gaffney. For the sole reason that they have a rock solid reputation for mapping a whole range of cars (ask Ross9 about Jacq's T4 for example) and they are about 25 minutes away (I wouldn't have to wait 6 months until the tuner was in the country or travel the length and breadth to get it done.. ). If my spec changed in future then it wouldn't be a chore to have the Unichip remapped for future mods - but then again this is a piggyback option and not a remap - which is why I differentiated the two before.

Some other options are:
Greddy eManage/eManage Ultimate
Civinco
Megasquirt
Gems
Hydra
Haltech
Link
Motec
Omex

It all depends what the OP wants and what he has in terms of resources local to him or is willing to travel for and what he wants to spend and what his future plans are and whether he wants a map or an standalone ecu or piggyback..

Haven't heard much about unichip so let us know how it goes....when you getting yours chipped ?...

once I'm completely happy with mine and have all my 'niggles' sorted I'll get it chipped- not too much to do now though..

EDIT: link to Unichip info:

UNICHIP

Is that you russ ???, crikey pangster i know you copy and post but that isn't one and i'm sure russ posted that almost word for word..lol...c'mon if your'e that worried about niggles being sorted you must know who you trust to map it..unichip then..
