no worries man............thanks for your advise and recognition, that others have used this same turbo kit on dc2r

cheers

i got some info guys...............
finally spoke to AVO today, and let them know the prob im having, they put me on to there tuner rob here in melb, and he advised em that we are running too much timing, i told him that most boosted hondas love timing with boost up in the vtec range and that we have discovered that the rear housing is too small for the type r application...............

he said nah mate................ur running way to much timing, i said well, on 8psi and 20degrees timing, it is detonating its head off, and 20degrees is only 4 degrees higher than stock..............he said that when the do there turbo hondas they drop timing to 14degrees and sometimes lower, and i would be looking at making about 145kw at the wheels..................

i literally laughed at him on the phone...........lol

anyways..................i'll be pulling off the turbo hopefully in the next week or so and have the machine/hiflow work done and back for tuning to see what we can come up with.............

again, thanks guys for ur input and sugestions...........

again, i am not slaggin/bagging avo, i am just stating what they told me and the issues im having....................

You should understand that the power figures they qoute are from roller dynos, NOT hub dynos

No qoutes figures off a hub dyno except for you

i understand that..............
but the main concern here, is the amount of timing they claim to run, and what we are running...........
avo claim that we are runnig way too much timing............

but i know for a fact as JIMMEH quoted, that its nowhere near too much

plus, im not chasing power........trying to make it a nice smooth curve....without detonation.............

Not exactly

If you're advancing the Dizzy AND adding timing on the fuel maps, then this is not good.

otherwise, what you're saying is correct and +20deg timing over the stock 14deg of the dizzy is OK, but I wouldn't go anymore.

who is tuning your car ievaq8?

no offence.......but are you a tuner???????????
coz my tuiner, has years of experience and knowledge......................in tuning boosted hondas, with stock and modified engines

u knwo who it is.....................im in melb...so.....................

If that's the case he sould know that +20deg is a bit much bro...

I'm only running +5-10deg max, just over stock in fact on my boosted D

I know B's can take more timing than D's but +20 seems a lot to me..

Hope you have aftermarket head studs instlalled?

how much boost you running????????? maybe u got low timing to compensate for the higher boost your running??

he does no what he is doing..........and is happy running above 24degrees, ofcourse, you cant just det it somewhere andf thats it, where ever the motor response the best, the timing will be adjusted to suit

but yeh i could definatly retard the timing and just run more boost.........same shit......................

head studs?????????
the motor is dead stock....top to bottom...............

Only running 10psi man

Yeah head studs are to stop your head Gasket blowing from detention..

I'm running ARP Studs with the rest stock..

Look - you have no idea who I am or what my background is, yet you're quick to pass judgement... Your perogative.

However, your problem (if you want to listen or not is irrelevant) is a result of too much timing (AVO guys are correct). 24deg advance for 8-10psi is overkill. It only takes <1 degree intervals for detonation to occur.

I suggest you re-read and understand what I wrote earlier.

If you dont believe me, try wind back ignition timing 4degrees to +20deg and leave the dizzy where it is. You will likely GAIN power and rid yourself of the detonation issues.
The advance timing is igniting the a/f mixture too early and combustion temps are rising too high causing detonation. This is also a function of cam timing.

Also
1. Use a EGT sensor in the tail pipe to read temps. Report them back here.
2. What are your a/f mixtures in boost?

Im here to help you so dont be quick to be judgemental.
