Re: Tik Pipe kit Roadster 82cv

... Actual noticeable effect??? negligible.
Same as the TIK material, in reality the noticeable effect is going to be barely noticeable whether it is a silicone TIK, a home-made one or a 74kw one.

Above interesting observations support my theory that the intake losses are very small, hence little or no scope for any improvement.

"Upgrades" to the intake system may only result in small, almost negligible worsening of intake flow so not noticeable unless one carries out accurate air flow measurements. Therefore better not tampering too much and just carry out normal maintenance. Removal of casting flash perhaps but more important to keep a check on seal at connection of TIK pipe to turbo inlet and make sure all connections in inlet duct are correctly made.

Re: Tik Pipe kit Roadster 82cv

If difference is only ever going to be negligible why did Smart make 3 versions?

Cheers!

Re: Tik Pipe kit Roadster 82cv

There are four different versions as far as i can tell. Reason: Different engines and turbos.

Re: Tik Pipe kit Roadster 82cv

lots of "negligible" increases add up to a more noticeable difference

Apparently not......apparently this type of 'upgrade' is actually a downgrade worsening performance.......if you believe everything you read of course

It depends on how well it is done. Yes, you will most likely end up with a small worsening if you just fit any of the expensive silicon or Brabus TIK pipes. Streamlining is what is needed plus accurate measurements to confirm whether the modification was an improvement on air flow. Sadly nobody seems to do that. By the way, quite a touchy subject this for some.

Re: Tik Pipe kit Roadster 82cv

I wouldn't rely on 'makeshift' apparatus and readings/formulas which would give a rough estimate at best. The best way to actually equate these upgrades/downgrades would be to accurately measure the power output to the wheels of the car - after all thats the whole point of the upgrade and what most would be wanting to achieve by doing it. Best way i know of has already been mentioned, sticking it on a rolling road and measuring it properly im sure this has already been done many times in the past on many many vehicles, if these measures actually degraded performance im sure we all would have heard about it by now and steered well clear. Also companies making these filters and tik pipes would have gone under years ago as no one would have bought there 'downgrades' - im no expert but it sounds logical to assume all these points.....

Re: Tik Pipe kit Roadster 82cv

I wouldn't rely on 'makeshift' apparatus ...

The picture may make some laugh but it is really a scientific instrument called a manometer. Very accurate indeed and does normally not require calibration. This one is a whole lot easier to read off compared to a standard U tube manumeter since the zero point is "fixed" by introducing a large volume in the form of the Miller Oils Diesel Power bottle.
By increasing number of measuring points along the inlet duct, one can easily identify where the principal restrictions are located. This one can not do by placing car on a rolling road.

Another thing is sensitivity of the instrumentation. Air flow losses in intake duct before turbo are so minute that differences between two TIK pipe designs can't be detected by rolling road tests. Of course no problem for the very sensitive and accurate "makeshift" apparatus as already demonstrated.

Re: Tik Pipe kit Roadster 82cv

I have been looking at the Suprex engine as used in Aviation applications, these engines are highly tuned, the diesel hits 80hp and the petrol is over 100hp. It's rather interesting that both the petrol and diesel engines seem to use silicone induction pipes throughout and 'freeflow' filters too. I'd imagine the company that produces these are testing beyond what us hobbyist are capable of and for sure their work is subject to rigorous standards and inspection.

I am not too sure about their sanity. Looks like air filter is bolted straight onto turbo inlet without any pipe of any kind. No laminar air flow at all so can't be very smart?

Testing looks rather vigorous.

And your point is what?

Where can I find more about that?

If You want to be critical.... well I am not very impressed.
It looked like (in the first link) the engine came loose and slided foreward just before they turned it off.

I agree. Those guys are amateurs. Did you notice how long they had to keep cranking before engine fired?
