I've been running 1.0mm boost jets which gives me about 13 - 13.5 psi.

 

Putting in 0.8mm jets gives me 15psi and a little bit of det occasionally.

 

I see it I have 3 options.

 

1. Purchase another boost controller - Im loathe to do this at mo as last one just broke.

 

2. Drill out some 1.0mm to 0.9mm with a precision drill and try that.

 

3. Can I - Put a 1.0mm in onew side and a 0.8mm in the other thus giving the same as having 2 x 0.9mms in - Would the balance bar compensate or would one turbo work harder than the other?

 

Thanks

:nono: Dont mix them.

 

I actually found some 0.9mm ones for sale, and ordered them. But when they arrived they were 1.0mm :rolleyes: I was told on the phone "well 0.9mm mig wire will fit in them" WTF?? 0.9mm mig wire will fit in the bloody eurotunnel you :xxx:. They were advertised as 0.9mm too.

 

Still waiting to be called back about it and get a refund

Jay if you want a controller let me know and i'll sort you a good deal ;)

Jay there is a 4th option, stick with the 1mm , 13.5 is a safe level , you would probably not feel the extra 1psi that the 0.9's will give you at least at 13.5psi you are just within the limits of the injectors etc without pushiung everything to the max all the time :D

Cheers people, running 0.8mm was a buzz though - went like a bloody rocket :)

Chris, Im gonna sort out my finances, sell another body organ then I'll ring ya - can you pm me a price please.

 

Is it 555 injectors and bigger intercoolers to stop det happening at 15-16 psi - can the standard tubbies handle 17-18psi?

Instead of mig tips you can also use carburetor nozzles, since these are available in a lot more sizes (in 0.02 mm size steps: 0.80, 0.82, 0.84, 0.86, etc.)

The nozzles are also easier to remove then mig tips.

 

0.02mm mmm they sound good

0.02mm mmm they sound good

...should take you to about 350,000 PSI! Might get a bit of det tho...

Jay,

 

Why don't you get JD to remap your chip for more fuelling at the revs you are getting det?

because the injectors will already be at 100% duty, the injectors would very probably have been at 100% from about 14psi

That probably is the case but the only person to qualify that would be John, or he could retard the ignition timing map slightly for him.

Mark , so you retard the timing and lose power to add one psi of boost :rolleyes: if the car is detting then you need to back off, retarding the timing defeats the object of adding 1psi of boost , tbh you would get more power backing the boost down and advancing the timing a little more , but as you say John would prob be the best person to ask.

 

Jay what chip are you running ???

Im running a JD special :)

 

So what do the standard tubbies run out at - 17-18psi?

I presume a set of 555s and bigger ICs and I can run ok at 17psi ish

Of course you lose performance here,I never disputed that Ryan, but it sounds like a cheap alternative option for jay!

 

Jay the best thing here is to return to the setup where you were getting no Detonation, have you removed your PRVR system as this maybe causing your car to lean out slightly?

 

15 psi is all the stock turbos can take for them to have any sort of viable lifespan.

i think using mig tips and the like can cause aggressive boost spikes, might be safer using a quality boost controller !!
