Yer not on the Mania sit anymore :?:
I belive it was an AVO manifold but car't find anywhere to buy it
the 1.8 turbo manifold are hard to find :evil: but I dont care any more :D
If you are after a 1.6 manifold and dump pipe. the ones on Ebay look ok
will be buying one if I can't shut up the intake moise on the NA6 Spercharged Beast :x

AVO manifold brand new from AVO for $715ish.

Best bit of gear available IMHO.

so for $450 it was a good price? YER :D

Well I got my car on the dyno today and I made 104kw
not what I was hoping for but nice and safe at the moment
On the dyno I bump up the timing and gained 5kw but didn't want to over stress a 200 000 + engine to much. Besides 104KW is enough at the moment . Better finish my new engine and save for a bigger turbo :D

from what i have read thats not a bad return without a IC. :)

Glen did you use a FMIC when you did your turbo covesion??
Any pic of the engine bay ?

Glen dont worry followed your WWW and had a look
pipe dissapears Looks good under that Bonnet

cheers but i still have neating up to do just been to busy enjoying it :) :) :)

i used 2-1/2" pipe all the way, you can use 2" pipe into the inlet side of the intercooler so then you should just have enough room to feed it straight down instead of going across the front of the pulleys/belts like i did

i reckon you should go a cheap intercooler if your going to save for that engine rebuild. you can pick up GTX Familla one with piping pretty cheap. i reckon you might notice a fair upgrade in power without adding more boost :)


on the downside i would think you would have to re-tune it though as it wont spool up as quick with an I/C.

You will obtain more power/torque without a IC (no pressure drop), than with one.

But for sustained boost it's a benefit to have an IC as it avoids heatsoak.

really, i thought the colder the air the smaller the air molecules. the smaller the air molecules the more air you can push in for combustion hence the air fuel ratio. the more fuel+air the bigger the bang.
this is why turbo's run better in cold climates.

it's all about the size of the molecule, the smaller the better.

Yes really.
Heatsoak is the key.

The molecules dont get smaller, they are closer together (Chem 101) as the energy of the charge is decreased (cooled in laymans terms).

For a single power run the loss of pressure across the IC is greater than any possible cooling effect derived from it (Turbos 101)

yep, like i said if you run a intercooler you will get a much better result than without one.

you can go into all your fine details of correct terms but i really cant be bothered posting bluntly obvious facts which is common knowledge :)

i just don't want too. :lol:

Ouch touched a nerve hey :P

What your saying contradicts common knowledge.

Believe what you want, however the fact is your statement was based on inexperience and lack of knowledge about the workings of the system.

(/please ignore the following)

Common knowledge 101
An IC will have a pressure drop across it.
Power is reduced because of this pressure drop.
An IC will allow sustained higher charge densities.

From this, it is also common knowledge
a) that for sustained use an IC will be of benefit at maintaining power.
b) an IC will impead maximum power

(/thankyou for your ignorance)

Cheers

just one other thing russell regarding whether your motor is liking the boost or not but you see this valve thingy here

Image

if you leave that off while driving (wont do any damage) and of course block the other end up. if it spits any oil out or you see any oil splatters from this point its a sure sign your motors seals arent holding up.
this is somthing that Anthony told me to look for with mine :)

There will be no pressure drop if we are talking about pressure in teh intake manifold (where every MAP sensored car I've ever seen takes it reading from). Boost measured in the intake manifold is the most accurate gauge of what's going into the engine (with the technology readily available to the market).

If the manifold pressure is the same the intercooled car would make more power and torque due to lower air temps.

The only place your theory would hold water (or hot air) would be if you were for some reason limited to measuring boost at the turbo outlet, rather than the intake manifold.
