Std R33 Intercooler

Hi

I have read in many threads that the Std IC is pretty much useless & something about a *pressure drop* after 6000rpm which infact causes the turbo to have to actually work at alot higher psi than the reading showing on gauge (taken at the plenum) & that this is the main reason that you should upgrade to a FMIC before increasing boost as its will have better flow etc...

Could someone please explain this to me as i do not really undserstand the whole concept?

Also if i were to upgrade to a larger R34 GTT side mount would this eliminate the pressure drop or has it something to do with the piping etc & the fact that its a side mount?

Any help appreciated as i like to know all details (why is it better?/how things work? etc) before i do any mods

Cheers

Noel

www.are.com.au has an explanation of static and dynamic pressure drop.

with a standard turbo an R34 GT-t intercooler is an improvement and are cheap to install. they bolt straight up to an R33. there is no truth to the 6000rpm theory. if you push more air into the IC than its interior design will allow or beyond its ability to cool you will have issues. due to the same pipe run response is unchanged and you get an improvement in keeping charge temps down over a standard R33 SMIC.

(ps. i have an R34 SMIC if you are looking for one)

how much better is the R34 stock smic over the R33 stocker ?

I might be interested.

Also, while we're at it, is there much difference in response time when running 80ft :blink: of piping for a fmic, compared to the stock side mount's shorter piping ?

      My thought is if you were just moving it forward and the upstream geometry remained the same, then no difference at all. But because the current one has the filter direct into the AFM inlet, you effectively have the best chance of a completely symmetric air flow profile upstream, and in, the AFM, whilst the aftermarket inlet thingo has a (small, to be sure) bend between the filter and the AFM. That would bias the flow to the outside of the bend (downstream of the bend) which might well reduce the size of the signal seen by the AFM, for the same total flow rate. Having said that: If you're proposing to make your inlet look like a hybrid of your existing one and the aftermarket one, such that there is no bend where the filter is clamped on... then I say it will be just fine. If there is going to be such a bend, then, if you can align the insertion of the AFM blade such that it is at right angles to the plane of the bend, then there is a better than even chance that the centreline velocity where the blade is will remain more or less the same, and the velocity will just be a little faster to the outside of that, and just a little slower to the inside. **This is not professional investment advice and you should consult a suitably qualified ouija board, tea leaves or the intestines of a goat for more accurate prognostication.

      Blue/grey smoke after idle

      By pacman_1219 · Posted

      Hi Tao, Thanks for your reply.  It's been a while and I managed to get the valve stem seals replaced with the head on the car.  Unfortunately this didn't solve my issue, the car still smokes a lot after idling (to be honest during idle you can see a bit of blue smoke from the exhaust), same after deceleration. I will try disconnecting the valve cover breathers, do I leave the PCV valve in? By engine oil drain pipe, do you mean the turbo oil drain?

      What about if you just give it direct 12v and earth?

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.
