went to see jeff on saturday to have a conzult

 

unfortunatly (well fortunatly) there were no problems at all. so jeff took the car out for a spin. he then confirmed what i had suspected- it was really slow.

 

after a bit of tinkering Jeff suggested the problem was with the recirc valves as i was only making 4psi and disconnecting the wastegate pipe only increased this to 5.

 

i put on the replacement valves and the results were better but the car was still not that quick.

 

after a bit of tinkering in the week i pinned the problem down.

 

in my less informed first few weeks of ownership i replaced all the vacume hoses including the wastegate ones. guess what. i had not realised that the standard setup should have restrictors in them:headvswal

 

now installed the restrictors and a set of 1.3mm boost jets and a boost gauge and im now getting 11-12psi.

 

all i need to do is sort the boost leak i can hear (hoping to get a performance increase from this too)

 

so let this be a lesson to all. dont assume anything

 

ps big thanks to jeff for the help and reassurance

Great news mate! Now crank the boost up more :D

will do once i have a chip fitted:D

 

need to put my manual box in too

 

almost had a bit of wheel spin earlyer:shock: its not done that before.

Wait till you get upto 14.5 psi - it feckin wheels spins in the dry now :eek: :eek:

Nice one Peter.....

 

....bring on that XKR!!

 

Richard:)

dont think its that quick yet.

 

we will see.

 

if all else fails i have a lotus 7 style car i am not far from finishing which has a 300hp turbo red top and a twin turbo lexus v8 to go into my 200sx. so ill get there

Hi all,

 

Talking of boost, mine runs up to 17psi according to the Blitz and only stops at the limiter. Any idea how much bhp it's making? How much more can I turn it up?

I'm assumeing the engine is untouched.

one more thing, in the boost settings, what is GAIN ?

 

Cheers

Gain is how quick the boost kicks in (low Gain = more gradual boost) and high gain = a big kick of boost but runs out of puff quicker!

 

Also with an untouched engine id knock down from 17psi as you wont have sufficient mapping or fueling for it and be ready to blow up your engine from major case of DET!

Thanks Munny.

 

I think it has a different ecu. 17psi is during the scramble feature. I normaly run it at

60%, am I right in thinking that it is 60% of the exta power, around 12ihs psi.
