wojtrek Posted June 2, 2012 Share Posted June 2, 2012 Hi, I just wanted to post the temps I logged today while driving around. I read that this SMIC should be fine for 500-600hp, but I don't think so - I have a relatively big single turbo running today at 1.1bar (which is nothing, as it's capable of 650hp) and a 60 to 120mph pull through 3rd, 4th and 5th raised the intake temp from around 25C to 63C. The ambient temp was 15C, so that is almost 50C more than ambient during a not-too-long acceleration. The sensor is just before the throttle. At this boost my car dynos at 450hp. So, 450hp, 1.1bar, and it looks like the GReddy SMIC is having enough. Has anyone of you who owns the Chris Wilson SMIC logged temps while driving? regards, Wojtek Quote Link to comment Share on other sites More sharing options...
Littler Posted June 2, 2012 Share Posted June 2, 2012 There was a member on here TLicense who I think successfully ran a 600bhp single setup on the chris wilson SMIC, I'll have a look for the thread for you Quote Link to comment Share on other sites More sharing options...
Mugello Posted June 2, 2012 Share Posted June 2, 2012 Might sound silly but is the cooler getting a clear air stream to it ? 50degrees above ambient Quote Link to comment Share on other sites More sharing options...
Nic Posted June 2, 2012 Share Posted June 2, 2012 (edited) Another temperature sensor before the intercooler will enable you to work out how efficient it is. Edited June 2, 2012 by Nic (see edit history) Quote Link to comment Share on other sites More sharing options...
wojtrek Posted June 2, 2012 Author Share Posted June 2, 2012 Of course it is efficient in some way - I'm just saying it isn't efficient like I hoped it would be. I never tested the stock SMIC, but my friend's supra, which I also tested today, that has an AEM EMS2, which logs manifold temps shows 12C higher than ambient temps at 1.7bar! He's basically running same sort of turbo but has a GReddy 4 row, the biggest IC there is. At 1bar the temp was only 8 degrees higher than ambient. that is 40 degrees difference at same sort of pressure and power. I have a stock front bumper, so nothing is in the way of fresh air...

Josh Posted June 3, 2012 Share Posted June 3, 2012 (edited) There was a member on here TLicense who I think successfully ran a 600bhp single setup on the chris wilson SMIC, I'll have a look for the thread for you I've got that SMIC now. I'm sure the CW one is pretty efficient. Here are the details; Previous customers have run these up to circa 600 BHP whilst monitoring air inlet temps to the engine,, with great success. They are all alloy, with fabrication to F1, aerospace standards, almost a shame to hide it away. I wonder if Chris has details on the results.

Yeah, I read all of that before, but since these are so hard to get hold of and I found something even more rare - the GReddy SMIC, I thought it would be alright. What is an OK inlet temp at around 500hp? Because I can't see my temps staying at 60degrees C after I raised boost from 1.1 to 1.5bar Quote Link to comment Share on other sites More sharing options...
Yakky Posted June 7, 2012 Share Posted June 7, 2012 Are you getting inlet temps from stock sensor? (which is post-intercooler and used by ECU) You should be seeing 30-40 under boost (1.2 bar with larger turbo's - that's around 500bhp), even sustained and repeated - nothing like 50 unless you idle in traffic with an aftermarket intake. No problem anyway after 30 secs of moving. Quote Link to comment Share on other sites More sharing options...

No problem anyway after 30 secs of moving. I'm using a multimeter with a temp probe which measures temps 5cm before the throttle body. I'm guessing it's even hotter in the manifold. The test was conducted first on my dyno with a huge (1meter diameter) high power fan and then on a motorway, and repeated many times. Same result all the time And like you say, even after a stop at the lights, the temps go back to normal in a matter of seconds. What I'm guessing is that since the SMIC is so 'narrow' (less than a half of a normal FMIC) the air does not have enough time to cool as with a 'wide' one. The GReddy SMIC is quite thick, but 'narrow'. If you touch it after a dyno pull it's barely warm around the outlet, hence my guess as to why the air is so hot... but maybe I'm talking rubbish Edited June 7, 2012 by wojtrek typos (see edit history) Quote Link to comment Share on other sites More sharing options...
Yakky Posted June 7, 2012 Share Posted June 7, 2012 Do you have a hardpipe to the throttle body? or stock rubber pipe? how have you fitted the sensor? What type of sensor have you used? To measure airflow it usually wil be short steel shaft with the actual thermocouple inside. Quote Link to comment Share on other sites More sharing options...
