im off for a remap tomorrom with these guys http://www.torquetronix.co.uk/rolling-road-and-dyno.html as i live in northen ireland they use hub dyno's anyone know if there any good??
the guy tells me im looking at about 190 bhp from my agu with my full milltek decat system and induction kit does this sound about rite
-
Is it mapped?? If not 151hp, 1hp over standard with mods.

Yes 190 bhp is about right - i have the above mods (but with a sports cat and just a panel filter) on an AGU and got 189.6 bhp on the RR :smiley:
-
well its off to be mapped tomorrow so i will let you know what i get out of her lol
-
You will get about 180 bhp. :grin: in this heat . :cool:
-
been for the map first dyno test not mapped show 142.8 bhp but the guy said as the car is 13 years old that was about rite?? anyway he took the ecu out done the chip then tested again this time 169.8 bhp he said it should be around the 190 mark but was losing boost he could see on the screen of the dyno that it was droping off. i have a blitz dump vavle on the cold side he tested again and said that dump valve was the prob it was losing boost out of that and that was losing me some bhp he also said it may be the spring in the dump vavle thats weak would this sound rite ?
he told me that the 18t's dont like these type of dump valves but as mine is there to get the forge one with the stronger spring this should cure it
any help would be great my boost is now around 17psi and holds at 14psi

there was a golf being done before me and that made 191.4 bhp

In a word yes he could well be right :smiley:

Did they do a vag com check before loading the new map?
-
boost is about right but if it is a blow off valve then it will put your power down as it did on mine when it was on the rollers with my blow off valve custom cat back silicone tip weak actuator dodgy maf and a fooked pcv system i still managed to get 185bhp and 226 ft lb of torque and since replacing all the parts the difference is night and day you could feel the difference after the map but now its like a new map again main cause was the dv nick at r-tech changed it to show me and the figures changed instantly as the blow off valve was releasing the boost as opposed to recirculating it causing a loss in power
-
do you think i would lose that much power from the dump valve?? i the valve was on the car when i bought it so i dont have any of the original pipe work to put it back to stock where could i get this lot from???
-
i dont know if it would lose that much but i can say from seeing it myself that mine was losing power from it as for the pipe work you may need check to see if any are being broken or summat or dealers but they gonna be a bit more expensive
-
anyone got any pics of the pipe work how many pipe there is and how it looks as mine has blanking pipes in place and not stock need to get this vavle off lol i think i will need a new intercooler pipe too as this has been cut for the dump vavle to sit were it does
-
get a pic up of how it is now and then ppl can suggest exactly what ones you need as its easier than guesssing whats there and whats not :wink:
-
I would say its losing power from the dv .Its got a weak spring in it, set up for a non mapped car. I would give it a good service too. Check for any boost leaks ie: oily boost pipes.
-
the car has just been serviced oil,filter,plugs,cambelt, heres the pic's on how the pipes look now (http://i1249.photobucket.com/albums/hh519/wolfie19811/P1010797.jpg)
(http://i1249.photobucket.com/albums/hh519/wolfie19811/P1010793.jpg)
the big question is would i really lose 20+hp with the dump vavle??
-
If its not a twin piston dv it deffo won't work well, get a recirc valve and take the recirced side back to the tip (r/h/s plugged pipe) with a long pipe
-
I have seen them valves lose 20bhp+ with ease.
You also want to check the PCV system for leaks.
Other things to check are throttle body opening, cam timing, over reading MAF, naf N75 and weak actuator
It get a good picture of whats going on you will need to log blocks 013 and 025. (ebay for a vcds lead)
I would ecpect a good running AGU to make 150-155bhp in stock form, any lower then I would state to look for issues.
-
well first off im getting rid of that dump valve hoping to buy 007p or 008 not sure which is the best of the two??
see in my picture the two blanking caps do i just put the dv in the tip and then the long pipe from that to the other blanking cap?? where does the small hose go from the top of the 007p go??
thats if all i have missing i.e one pipe and dv?
so sorry for all the questions guys i ent had the car long and i want it running rite.
pcv is all good i changed the crank breather as it was split all other pipes around that look good.
-
Get the 008 as its newer and put it where it is now and take a pipe to the tip leaving the blank in the charge pipe is
-
so leave blanked the cycle in red and then run pipe from cycle blue to where my dump valve is now put replace it with 007p or 008

(http://i1249.photobucket.com/albums/hh519/wolfie19811/P1010793-1.jpg)
and this will work fine??
or am i just better off setting it back to stock but using the forge 007 or 008
-
Forge 007 will be fine and a much better bet than what you have fitted at the moment.
-
the 008 is the newer version. but how the hell you can improve something so simple is beyond me
Seal positioning
lol
-
just spoke to the guy who mapped my car to get some more info he said when tested in stock all was fine not losing boost but after re-mep around 4500rpm the was a drop on the graph showing it was losing boost and it was the blitz dump valve causing this hence the loss in bhp but could not tell me if i would be losing 20+ hp from just that.
im going to replace the dv for 007p back in the stock place i.e on the tip could someone tell me if the small pipe from the top off the 007 go's to the inlet
-
could someone tell me if the small pipe from the top off the 007 go's to the inlet
Yes it does.
-
ummm that's not a Blitz valve, it's a Bailey...
anyways yes you will ideally need a new intercooler to throttle housing pipe to get rid of the cold side version you have there now. You will also need the pipe that goes from the metal charge pipe you have blanked off circled in red in your picture to the stock DV position on the turbo inlet pipe (TIP) you have circled in blue. See if someone is breaking a Golf or recently replaced theirs with silicone items to get the ones you need
-
the pipe you need for the DV is on the bottom left of this pic

i was having issues with mine when cold when you accelerated it didnt go anywhere
since fitting a forge its been 99% right. it has 160k so im not expecting the car to not have a leak or 2

my prob ent when running cold mine's down on power not sure yet on why this is hope its from the dv i have on it. just bought a 007p its on its way to me just need the pipes now and then see if i get the 20+bhp ive lost the guy who mapped it is going to dyno the car and log it once i get the rite parts hope to see the 190 mark then.
i might buy a n75 valve aswell as mine has never been off the car by the look of it :smiley:
just found these so i mite buy them and forget the stock piping
http://www.ebay.co.uk/itm/160764236564?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649
-
is that all the pipes that are used in the engine bay?
-
no just the pipes i need for dv / n75 :smiley:
-
those will be fine mate, you may need a length of 3mm pipe to go from the new DV location to the inlet manifold again too
-
IMO all these test should be part of the the remap to make sure the car is fit to tune. A good cheap smoke tester is around £500, pressure tester £30 and the main on a tourch to do visual inspections.
If you can log blocks 025 this will show whats really going on.
If you do get stuck I am sure my mate Joe will help you at http://www.chippedire.com/ Just mention my name and he will look after you.

Can he not just fit the new forge valve where the baileys is?
-
Can he not just fit the new forge valve where the baileys is?
Not a good idea, have you seen how restrictive the relocation pipe is?
-

I dont know what the relocation pipe is. :laugh: :embarassed: Just a thought, as I have the same baileys valve and want to put the standard back on for now in the easiest way. Is it possible to just blank off the location of the baileys valve once its removed?
-
nick the phone call i had with you was great help thanks i am going to buy and put the 007p where it should be for a start and change the intercooler pipe + buy the pipes needed to put the 007p in the stock postion and take it from there the guy who mapped it will run it again for me and log it for free so lets hope doing the bit first helps if not the log should show whats going on

-
still waiting on my pipe work to come :cry: what colour spring will i need to use in the 007p???
-
fitted my 007p and pipe work and wow what a difference i can tell stright away lots more power off next week for a run on the dyno to see what my powers at now also having it logged to see whats going on hope im around the 190 mark now lol
will keep you posted on the out come
