Random FMIC information with a little turbo info mixed in.....

[David Buschur]

I am going to compile some intercooler information I have here along with the type of turbo used. If I have the engine size (2 liter, 2.3 etc.) I will list that information too.

All data was gathered doing testing on our AWD Mustand Dyno. Same fans were used although the testing is scattered at different times throughout the year. This is in NO WAY back to back testing of any particular intercooler. No horsepower data, no pressure loss. Simply air intake temps I have, boost levels and the point the car reached full boost as that's important to see how long the car was in boost compared to tempurature increase.

For anyone that I have tuned here with an AEM, if you don't see your brand FMIC on here please send me a PM with your name and which FMIC you had and I will post the data. This would be very helpful as I can't remember everyone's combinations and want to make sure this data is correct.

This is nuts:

2 liter
BR GT35r header kit
Old original FMIC (this is one 15+ years ago we thought was the best)

Starting AIT 107.6 degrees
Ending AIT 194 degrees
Peak boost 31.80 degrees
20 psi at 4793 rpm

Same car as above but we designed and built our new FMIC for the DSM

2 liter
BR GT35r header kit
New 1G DSM FMIC

Starting AIT 86 degrees
Ending AIT 107.6 degrees
Peak boost 37.40 degrees (NOTE 6 more psi than the base run!!)
20 psi at 4695 rpm (NOTE, 100 rpm sooner to 20 psi!!)

[David Buschur]

Starting AIT 64.40 degrees
Ending AIT 93.20 degrees
Peak boost 27.73 psi

This is the same car as above, one day apart after a change to the Race FMIC

Starting AIT 95 degrees
Ending AIT 100.4 degrees
Peak boost 33 psi (NOTE 6 more psi and still cooler temps)
20 psi at 3723 rpm

Dave, first off thanks for the info, it is highly valued and taken for just what it is, some logs at various times, not a direct comparison, yadda yadda yadda. Still the data says a lot.

Question: is it common to see and extra ~400rpms of lag when stepping up to your race core, even if you're coming from the (already fairly big) deluxe core? Or does this depend on the turbo...i.e. a stock-frame turbo like the IX or 20GLT will see more lag on the race core than say a 35R?

About a month ago I upgraded my 94 Talon from the "old" BR race core, 2-216 to the new 4" BR core, wow, way faster boost repsonse and nearly eliminated all knock on pump gas and the car is being pushed very hard on pump, New core is the best upgrade ive done in a long time.

Starting AIT 91.40
Ending AIT 113.00
Peak boost 25.48
20 psi at 4125 rpm

[David Buschur]

I noticed that one example I posted and the additional lag. I posted it anyway because that how I operate, post the truth and be done with it.

I do not feel that is typical and have other logs of cars with the same race FMIC's on it and same turbo that have much faster boost response. Looking at it now I wonder if there was a leak............

Starting AIT, 95

Very intersting!! I was only able to run about 20 psi on 94 octane with my FP Green....Maybe this would help.......
