very happy with my rolling road figure of 293 :-)
only problem is i need a twin spark hks thingy lol
got it on the road and it wouldnt boost on second turbo :-(
found a broken vacuum pipe under the inlet mani. fixed that then found one leaking which comes off the side to the boost controller.
i tightened that up a bit and it BOOSTS fine in 3rd and above but not 1st or 2nd i think i need a new vacuum pipe as i guess it leaks more in 1st and 2nd DOES THIS SOUND ABOUT RIGHT?
Ok, your boosting issue in 1st and 2nd points to the turbo control solenoid/actuator. This actuator requires both pressure and vacuum for it to operate at peak efficiency.
As found from a common resource for troubleshooting:
QuoteThe Turbo Control Solenoid / Actuator is one of the more complicated actuators as it requires both vacuum and pressure to operate properly. This actuator is controlled by two solenoids, (both are wired together to the one ECU output) one solenoid applies pressure to one side of the actuator and the other applies vacuum to the other side of the actuator. With pressure on one side and a vacuum on the other side of the actuator, the speed of the actuator is improved. A typical problem is loss of Secondary boost in 1st or 2nd gear at 4,500 RPM, but reliable operation in other gears. This points to one side of the Turbo Control Actuator not getting it\'s pressure/vacuum, so it will still operate but not quickly enough.
Quote"No vacuum to the Turbo Control Solenoid / Actuator is a common failure. This is typically caused by the one-way valve that supplies vacuum to the Turbo Control Solenoid / Actuator through the Vacuum Chamber. The one-way valve will leak, allowing manifold pressure to leak into the vacuum while under boost. "
So about 340~ hp at the fly, not bad at all.
What mods have you done?
Shouldnt need the twin spark with less than 300bhp, what plugs are you running? I use 10s and 11s and did have 310at the wheels, no problem at all!
top end of 300bhp and yeah the boost will blow the spark out.
i have down pipe back exhaust which is still very restrictive and an apexi and profec b boost controller.
right so it is either the actuator of the one way valve
i tried a one way valve off another rx and it didnt make a difference
however on thurs after the tune i had no boost in second at all and found my one way valve had broken.:-(
so i am confued I would expect it to be the valve but i have replaced it and it still does it.
it also doesnt boost till about 5500 in 3rd sometimes too
Quotei have down pipe back exhaust which is still very restrictive
just to clarify matey, do you mean you have the standard exhuast from the downpipe back...
if so get a nice de-cat on there :cool
i have everything but the downpipe.
but it has three silencers so quite restrictive
James it\'s pete,
It does\'t mater if you have 293rwhp I will still beat you round Brands. :D
You better give up now.
lol yeah then you woke up
maybe if my car isnt boosting 2nd turbo when we go LOL
You call that a turbo? it\'s as small as your willy :D and like your car it does not work all the time :p
So I ive been told
JOKE
We will just have to race for pink strips.
O by the way I orded my DJ01\'s £471 delivered. More money this time but there was no Special offers this time :(
Pete
whats your mum been saying lol
those tyres are the only rubber you are ever gonna use :-D
See you on the track!
lol
You have to resort to childish bafoonary. :spank
The only reason you have a car is coz you nicked all the parts off my bothers. LOL
The reason you pulled out of going on the track is coz your scard of being beatten by the LSD less drift EMPORER :3gears-rh :D
P.S. Your such a smelly yak!!! :D
Pete.
I\'ll see you on the track (in my rear view mirror)
or maybe in the kitty litter when you try and keep with me.
