Thread: ETS 4" FMIC vs. Stock FMIC dynotesting!

What a busy week... Whew... Well we finally received our 4" ETS FMIC core in on Friday as promised by Michael@ETS.





In between cars we found enough time to be able to jump on the dyno and do some back to back testing. We removed the front bumper to make it easier to swap out the intercoolers quickly to have as true a test under the same conditions as possible between the two parts.

We first started off with a rich dynopull in the upper 10's which we found odd. The Evo VIII baselined at 437whp or something ridiculousy low. I checked all hoses and orings, made sure the fans were on as not to escalate intake air temps making the car dump fuel etc. I tried another pull. The car made it to about 8psi before it sputtered. I checked the plugs, expecting them to be black and fouled as sometimes larger injectors spray pattern are more rough. Much to my surprise, they couldn't be more perfect looking and clean.

After about 10 minutes chasing my tail, it struck me. Wait a minute... I pulled off my INJEN conical filter to find this:



The MAF honeycomb was not only crushed, it was also ejected out into the air filter. I think this happened on the way into work as I shifted to 5th. I grabbed a backup MAF sensor and went back to work. All was well! {thumbup}

This day's dynotesting gave us a solid baseline of 479whp with no knock and 493whp with 6 counts of knock at 6900rpms as the stock FMIC would heat up. Through tuning and adjusting the boost, we spend a few moments trying to extract about as much as we could get out of the stocker as we knew we would be doing the same with the ETS FMIC. It was only fair.

After a few pulls and settling on our baseline numbers we moved to pull off the stock FMIC:



As you can see from the picture below, the FMIC is not only longer, but it is also an inch thicker with a superior bar and plate design with more a more advanced cooling fin design.





Luis and I popped in the supplied silicone couplers which replaced the rubber units from the factory. We used JGS HiGrip premium worm drive clamps which we stock here at TTP-Engineering. These clamps give an unlimited range of sizing and are strong enough to crush aluminum intercooler piping. They insure they stay put at high boost.



The fitment of the FMIC was great, it cleared the A/C condenser fan (yes we are and will continue to run a/c in Florida). There was a slight touching on the front bumper on the passenger side that puts a little stress on the bumper, nothing we can't live with.





Here are the stock FMIC baseline pulls. One is the baseline with no knock and the other one was pushing the limits of the stock FMIC as much as possible. 6 counts appeared at 6900rpms where it was making 493whp right before it dropped into the 460whp range with the timing pulled.

On the solid line with NO CHANGES to the tune or boost, the FMIC being the only change, the power output jumped to 511whp on 93 octane!



With additional tuning, the 4' ETS FMIC allowed us to add 1.1psi of boost on 93 octane and further manipulate the ignition timing to some great gains.

Here is the overlay of the FINAL tune on 93 octane with ETS 4" FMIC. It is overlaid over the peak pull on the STOCK FMIC hitting 6 counts of knocksums at 6900rpms due to heat.



Here is the overlay of the ETS 4" FMIC TTP Custom Tuned Evo over the stock FMIC with no knock:



All in all we have been impressed with the performance offered by the ETS 4" FMIC for the Evo 8-9. We have achieved gains in the 55whp range on pumpgas 93 between the two comparative dyno pulls with no knock. The ETS FMIC is a sharp looking unit with a quality fit and finish, nice welds and it came well packaged.



The addition of the new ETS 4" FMIC core complements the equal length single scroll FP HTA86 35R ball bearing turbokit we are currently running on this car. If anyone was curious what the turbokit looks like installed, here are some additional pics:



Next up is a MAGNUS V5 manifold on its way over from Marco in Canada. We will be interested to see the results of the next stage of testing. With the addition of the MAGNUS Manifold, we will be testing a 75mm throttlebody still on the stock ECU, IAC and TPS sensors!
