Bugger - 2 nd Turbo not kicking in


Dragonball

Recommended Posts

Hi guys

 

Just a quick one - have just replaced my hoses with new SVH - all appeared OK - but tonight noticed it a bit 'sluggish' and doesn't feel like 2nd turbo coming in

 

SBC-ID only shows me up to max 190 HP - a sure sign

 

Anyone any guesses on where I should look tomorrow?

 

Any hints?

 

Cheers

 

Paul

Personally I don't like silicon hoses as silicon is naturally very slippery stuff. You will need to ensure all clips are done up tighter that the stock rubber hoses and you would be advised to put clips on the smaller bore hoses that did not need them with stock rubber hoses.

 

You will just have to check all the new joints.:(

i put stork margerine on my hks intercooler hardpipes as it was a pain in the ass getting them rubber hoses on once you put them on they would not move to slide in position. second time i fitted them i thought margerine inside blue hoses

worked a treat and made sure they were very tight with screws. never had a mins bother with them

 

STORK margerine tip for today

ps the turbo problem the topic starter is having maybe its just a loose hose double check they are all on and in right places

hope you get it sorted

If it's hoses and 2nd turbo then I always check the tiny little hose connecting the VSV to the exhaust bypass actutor. It's about a 4m pipe, so tiny but can leave you without any 2nd turbo spoolup.

 

Look at the exhaust, follow it back to the engine, you see the O2 sensor. further up is a mechanical valve and actuator arm. Follow this arm to the actuator and check the pipe from it to the VSV, which itself is located close to the front of the engine with the boost control VSV.

 

Regards

Pete

Thanks Pete

 

So the wrist bone's connected to the arm's bone, the arms bone connected to the ect ect...

 

Not a clue where this is - but basically my kack handed attempts can effect the spool up!

 

back to the drawing board!

 

Cheers

The best lubrication we have found by far is caburettor cleaner. (yes, no jokes please..;)

 

It makes it real easy to get pipes on and it evaporates quickly so that you are left with a nice dry relatively high-friction joint.

 

Oil, grease, WD40 or indeed margarine isn't the best solution... You must have done them up very tight Mark!

Back in the summer i went into a chemist in Brighton (the gay capitol of europe) and asked for the largest tube of KY they had (need it for diving to get in to drysuits) and wondered why i got some funny looks , then realised it was the day of the 'Gay Pride March' through the town .
