TLicense Posted May 24, 2006 Author Share Posted May 24, 2006 LOL, I can assure you mate, that as it's being dyno'd/mapped before I get in it and turn a wheel, the faintest hint of surge will result in me fitting a FMIC. I'll let you all know how I get on! Quote Link to comment Share on other sites More sharing options...

I'll let you all know how I get on! Well hats off for at least being brave enough to try it Tony But I have a funny feeling you will find a boost crossover point where your side mount wont be able to handle the flow and charge temps start rising, But you never know it may bear fruit . Good luck with it all and look forward to seeing the results. Quote Link to comment Share on other sites More sharing options...
Guest earl3 Posted May 24, 2006 Share Posted May 24, 2006 Flow test on SMIC (stock and uprated) against some FMICs would be excellent, be great to see the restriction / pressure drop they create in black and white. for me, not chasing endless power the uprated SMIC sounds like a good compromise between replacing the worn out stock unit and something that can support a small sensible sized single, should the time come. For sure if you are persuing big bhp then it will rapidly become the weakest link, if you are persuing this sort of goal then a nice FMIC is also a drop in the ocean for the budget too, so it probably makes sense to just do it. Reg Reimer tested the stock SMIC vs the Greddy SMIC and the stocker flowed a bit more. Isn't the Greddy SMIC a shorter version of the 4 row (and hence higher flowing)?

chilli Posted May 24, 2006 Share Posted May 24, 2006 makes sense is reversion is when the pressure on the compressor output is greater than the force on the exhaust wheel? Quote Link to comment Share on other sites More sharing options...

chilli Posted May 24, 2006 Share Posted May 24, 2006 ahhh right, so high back pressures make this worse presumably, as does increased valve overlap with different cams Quote Link to comment Share on other sites More sharing options...

Guest Usmann A Posted May 24, 2006 Share Posted May 24, 2006 Uh huh John, Lovely mate, theres me and Mig trying to explain this is the simplest terms and no one has understood i think( no offence), i tried to say as best i could. ENTER TUNING GOD JOHNA(of chavailer fame) Here you come along and spout out some jibberish bud ... TALK ENGLISH MATE FFS! NO NEED TO COME OFF UPPER CLASS, YOU DID OWN A CHAVAILER AFTER ALL ...... :D THIS IS GOING TO BE A REALLY LONG ONE NOW. PS, CANT YOU JUST SAY YES I EXPERIENCE SOMETHING SIMILAR, AND THINK IT COULD BE DOWN TO AIRFLOW. IT WONT HURT YOU TUNING EGO . Quote Link to comment Share on other sites More sharing options...

Need4Speed Posted May 24, 2006 Share Posted May 24, 2006 There's a video clip somewhere showing high boost blowing a standard SMIC apart! I'd try one of CW's and put some sensors on the piping to measure temperatures. Quote Link to comment Share on other sites More sharing options...
Miguel Posted May 24, 2006 Share Posted May 24, 2006 TBH Chilli I think you had the grasp of it before John came along with the DaVinci version of what has been said more than twice in this thread:) There no denying That John has written it in a format that makes scence to the more knowlagble but does it really hit on what has been said over and over again in laymans terms. I get the feeling That when people try to help and put it in everyday language it gets frowned upon. But when written In University tech thats ok. John If you read the 1st question that Tony put down you would realise that the points have been covered and questions asked, Some of which still havent been answered by the people that supply the SMIC. Now this thread is branching out onto cams and throwing even yet more complication s into what was a very simple question in the 1st place. I can totaly undertsand Usmann's frustration with the thread TBH as it simply boils down to, WILL THE SMIC SUPPORT THE LARGER RANGES OF TURBOS/BOOST AND WHAT IS THE FLOW RATE CAPABILITIES OF THE SMIC. UPRATED OR OTHER> Quote Link to comment Share on other sites More sharing options...

I have visions of those disposible popcorn poppers you see in US movies, the stuff they hold over the fire / cooker and it expands into a huge silver foil thing.

Miguel Posted May 24, 2006 Share Posted May 24, 2006 I don't think it is a very simple question. I see it as part of a complicated system. If it was cut'n'dry I'd have fitted a FMIC straight away. But it isn't and I didn't. But then you never planed to go masive single or twins and want to maximise the stock system before moving on no ? In which case the SMIC for you is lovely. It can be made as complicated or as simple as anyone wants it to be but the underlying fact was that is was started to evaluate 1 component, Intercoolers. And now it seems to be going into the whole system, we will be on pistons and head flow design next. I think Chilli also hit it one the head, the talk on here has just masked a very simple question, Lets see some results for the SMIC instead of having a mass debate about what we "think" is the theoretical limits of them, Black and white real world figures. And sevreal of them would be nice, Stock Tubbies on stock SMIC then a CW or whatever ..then a full range of turbos ..only then we will know. Instead on going round and round and round and then throwing cams in and before we know it a full rebuild Quote Link to comment Share on other sites More sharing options...
Miguel Posted May 24, 2006 Share Posted May 24, 2006 Actually the above gentlemen are not top of the foodchain. There are books that go a bit deeper into the field. LOL no one said I was at the top of the field ..far far from it. Well at least I'm not top of the copy and paste field anyway My point is yet again on another thread it has been overcomplicated and post arent read in full before replying. So it just gets dragged out ..God knows how many times people have now asked the same question and have you answered it with you nice techie bit? , No, you are going into the workings yet again. For god sake someone just test the bloody SMIC and bang some results up. Quote Link to comment Share on other sites More sharing options...
chilli Posted May 24, 2006 Share Posted May 24, 2006 TBH Chilli I think you had the grasp of it before John came along with the DaVinci version of what has been said more than twice in this thread:) well I think I understood it, but the static + dynamic bit was a missing piece for me that is vitally important to understand why at the same (apparent) boost pressure with everything else being equal, there is more air flow (and also why cars make more bhp on the same apparent boost when they use larger turbos...) no need for anyone to be offended or put out by posts on here is there? Most people had an idea of what was going on it seems, sometimes a missing piece found by someone who has looked into it a lot makes it fit together, it helped me at least anyway. It's always good to question these things, while FMIC might be an obvious choice for most, for someone with more humble aspirations for the moment, a new, decent uprated SMIC might be just what I need and knowing the options really helps Quote Link to comment Share on other sites More sharing options...
