Those wondering about the limits of an upgraded SMIC

[VRMAN]

I know some people out there are looking to run bigger turbos on a sleeper-type setup. I have an SCM32 (54 trim) with the supporting mods listed in my profile. I was curious how the Dejon Tool Super-sidemount would hold up cooling higher boost without heatsoaking. They say it is rated to 400hp as well, I called Dave at dejontool and he said that the upgraded sidemounts can effieciently cool the 50 trim variants up to 18-19psi. But since I plan on running more along the lines of 20-22psi I also rigged up a C02 sprayer to combat heatsoak.

My reasoning for the Supersidemount was sleeper status and also that I had JUST paid full pop for my IC pipes when I had an 18G on there and switched turbos but wanted to keep my SMIC location.

I dyno'd my car the other week and put down 305whp/300tq completely untuned. Just all the parts bolted up and gas added. After the initial pull I checked the sidemount and it was still room temperature and no timing was pulled. After the second pull (2 minutes after the first) I checked the IC again and it was hot to the touch, so it only took 2 pulls to heatsoak the super-sidemount on my PTE 54trim. Now, this was at 21psi, which is what I am aiming to run on the street. With the boost set at 18 psi, it was pulling fine with no heatsoak for 5 and 6 pulls. So I think the Supersidemount and HRC sidemount are good on 50trims until 18-19psi. 20+ psi required that I spray the IC with water to displace some heat, so if you plan on running over 20psi on a large turbo with a SMIC, plan to rig up some sort of C02 or water sprayer on the IC.

Hope this helps anyone curious about running a big turbo on an upgraded sidemount. It is doable but for serious boost, you'll need a little help.

Good review. I have a supra sidemount and it cools my 16g up to 20 psi just fine. When I upgraded from the 16g I had timing pulled at the same boost.

Are you planning on tuning it and then dynoing your car again? I'm interested to see how much you can get out of that SMIC.

Yes I am. When I work out the few bugs I have then I'll be hitting up the dyno again. I plan on running 110 octane and am going to shoot for a 25psi pull and see if I can't put down 375whp. I'll have a water sprayer firing on the SMIC the whole pull. It'll be few weeks but I'll keep you updated. I love the idea of a big SMIC but it does have its limits but they are higher then I think the average person gives them credit for.

Thanks very much for putting up a review of this intercooler. I have the same one on my wishlist for my Big 16G and if it'll handle your 54 Trim at 18 psi, then I know it would be fine for my turbo at 20 psi on pump gas. Coupled with the lower hardipe kit, this is a real winner.

Here's to stealth and thanks again for posting your findings.

Isn't there an airflow factor involved here to. I know the Supra SMIC ect. can flow around 400cfm compared to a FMIC which is normally double that. Isn't there an airflow loss here which also contributes to hp loss.

This is kind of the same path I plan an taking, but with a few exceptions. For one, I'm going to stick with the stock SMIC as long as I possibly can. To combat knock and heatsoak, I will have a dual stage (two nozzle) water/alky injection installed - smaller nozzle pre-intercooler for heatsoak and the other nozzle just before the throttle body. I think this would net some pretty nice numbers considering the airflow restriction of the stock SMIC.

Keep us updated with your results!

One thing to remember - the fans that they use at a dyno give you no where near the airflow you would get if you were moving. A SMIC will get heatsoaked quickly when standing still in front of fans, but do a few pulls on the street and try the same thing. Chances are that the IC will be quite a bit cooler than it was at the dyno.

get a good water injection system, set it up exactly like guitarXgeek plans to set his up youll be amazed : http://dsmtuners.com/forums/showthread.php?t=41303&highlight=water+injection

i'm running the stock sidemount on my 14b/272s setup, dynoed 289whp/304ft-lbs. On the street during a 3rd gear pull, I'll see charge temps of around 150-200F. On the dyno, I was seeing 225-250F!! Surprisingly, on the pulls where it hit 225, there was no knock, and on the pull where it hit 240+, there was some knock above 5k but the dyno curve looked identical. I'm curious to see how this translates at the track, since I have yet to do a full pull through all the gears.

All good info. I also took out the fog light so there is direct air to the S-SMIC, you can see it through the bumper duct.

I didn't realize the fans didn't provide adequate air, thats good to know on the street it'll be slightly cooler.

I'll update this thread when new information comes in. Anyone else running a big sidemount post your thoughts/reviews in here.

After the initial pull I checked the sidemount and it was still room temperature and no timing was pulled. After the second pull (2 minutes after the first) I checked the IC again and it was hot to the touch, so it only took 2 pulls to heatsoak the super-sidemount on my PTE 54trim.

I'd like to know how long it takes for the IC to cool back down at idle, or maybe a fast idle. Unboosted intake has to suck the heat back out of it pretty quickly, from running cool air through the inside of it.

I was running the Supra Sidemount on my 50 trim. It worked well unless it was pretty hot out (>80deg) or I did 3 or more pulls in a row. At the track, it tended to heatsoak at the top of 3rd and into 4th gear. I was able to get an 12.3@111 with it though.

I haven't experienced any of these problems on my frount mount however.

Another update for you guys, I had the car tuned and boost leaks fixed as well. This time on the dynojet I put down 309whp but the big difference being that this time it was at 20psi and PUMP GAS 91 octane. So with some good tuning on the AFC I was able to put down nearly the same amount of power as the last trip to the dyno but with 9 less octane points then the previous trip. I had planned to go big on the dyno and see what max numbers I could get out of the setup but decided to go for real world power since the car is a daily driver and did it on pump gas. Also, we did 5 straight pulls and the SMIC got warm but not hot like it did when I went the previous time. Boost was only down 1 psi so that was kind of confusing but none the less the SMIC held its own. Hopefully I'll shoot for the big numbers next time. Still planning my 110 octane + 25psi trip to the dyno but I'm wondering how the stock shortblock with 125k miles is going to fair.....
