All New Intercooled Sc

I did a low compression build with Darton pro sleeves. 2.3L Whipple with IC was 470RWHP. I have not tuned the 2.9L I will post as soon as I get it done. If I had to guess I would say over 500RWHP
 
I went with the whipple because the 2.3L just bolts in place of the smaller Comptech unit. It also uses the same intake that the TB bolts to. The 2.9 or the 2.3 now uses the autorotor intake to mount the TB.
 
hey man since you in MD any insde on how mcuh it end up setting you back i was think about going SC but after seeing you setup man looks perfect i would love to see if in person i'm here close to you in VA rite outside off DC.

thnaks keep up the awwwsome work..

Pretty neat intercooler design you came up with there, what are you IAT's like now?

I've current got the SOS Kenne Bell S/C on my '00 stock 3.2L but no intercooler, I remember the tuner mentioning the IAT was around 160-170-ish between hot runs 15~20mins between runs. Ambient temps were around 68~70 (20-22 Celsius) I was thinking of doing the SOS intercooler possibly sometime in the New Year. Tuner wasn't sure if the SOS intercooler will heat soak under normal driving around conditions for street can anyone else comment on the SOS intercooler?

I have the SOS supercharger with intercooler. I had have it almost 18 months now. I do a 60-100 run (anywhere from 4 to 6 runs) almost every week. So I have logs in 100-110F weather and 50F weather. I just installed the B-Line Motorsports True Cold Air Intake. I saw slightly lower iat and my 60-100 time dropped from 4.1 to 3.989.

The problem you would have it you install the intercooler, is the intercooler is installed with a different iat sensor and it is installed in a different location then the stock location. I believe Chris from SOS stated they saw a +20F degree difference in the locations.

The data from my AEM shows that around 105F when not in boost my iat is 140-155. Its in the higher range if I'm running above 5500rpm and the lower range if I'm running around 3500rpm. My full throttle run from 3k to 8K has my iat at 185-200. The first run is 185 the second is 190 and the third very close to 200. All my runs are within 5-10 mins.

If the temp is around 55-60 then my iat when not in boost is 105-110. My run from 3K to 8K has my iat at 140-155. I constantly see a rise of about 35 to 45 degrees from a full throttle boost run (3 runs). Since in Vegas I get around 8psi --- (7.5 summer and 8.5 winter), the intercooler is working.

Now why is the iat showing so high even with the intercooler. Well my iat when not ever in boost is also much higher then ambient. I believe this is because of the location of the new iat. The sensor is heat soaking. I got some confirmation when I did a 3k to 8K run ---- the iat was around 185, I then applied the brake until my rpms was around 5K, then I went full throttle again. My iat remained at 185 and then it started to go down until it hit 170 then it started to go back up and ended at 185 at 8K. This caused my A/F to lean out compared to the run before -- 11.9 vs 11.5.

I looked at my iat tables in the aem and reduced the fuel pull (ie I made it just like the fuel add). The tuner was very aggressive with the iat table above 140F (where my fuel pull starts). My rationale was even if I was wrong the worst it would be was richer.

So with the intercooler you may not see significant lowering of your iat (since you can't compare them with your old reading), but your intake temps will be around 50-60% lower when boosting.

Hey Cptnsx thanks for the info, I take it you are running EMS? The IAT sensor issue you mentioned is that a new sensor SOS sends with the kit to relocate it then? Very interesting so you think the sensor itself is heat soaking. Do you think there is somewhere else the sensor can be mounted where it wouldn't be heat soaking up as much? I guess like you mentioned the whole point is to help lower the intake temps under boost, glad to hear she is working correctly, and as expected.

I have no intercooler installed right now, so I guess I can pull the IAT's with a code reader to compare a before an after. I do see around 11~12psi of boost just before putting the car into storage, and was seeing my AFR hit 10.5 on my AEM Gauge under full boost levels she is running on the rich side for sure. I do have some data from my last dyno tune, but not sure if we printed the IAT's out either way I think they are still stored with the dyno tuner anyway. I'd like to run some more safety into the stock motor buy reducing the intake temps under boost, we are generally cooler here in Toronto area most of the year, unlike AZ. :biggrin:
