Terry Burger hit up the dyno recently with his MOTIV750 kit and here is the result.

Was able to finally get our 135i up on the dyno today for a little tuning with the new MOTIV kit. Overall, the kit is pretty impressive. Build quality is top notch and everything fits/works as expected. Before I go any further I should mention that BMS works with ALL turbo kit manufactures. So I don't want this to turn in to a kit A vs kit B crap fest. I've been very happy with the FFTEC top mount kit on the car and switched over to the MOTIV kit because it struck me as elegantly simplistic and once I saw the design I just had to try it out for myself. Plus, I've known Jake & Bobby for years now and know they only do top notch work.

I had AC Fabrication do the install and some fab work. They make the VM top mount kit and are also top notch fabricators. Since I'm running a 3.5" catback I had them make a matching 3.5" dp, and since I have a custom intercooler a custom chargepipe was required to mate everything up.

Today's dyno testing was on E70 running essentially the same tuning and boost profiles as I used to run on the FFTEC 5862 TS kit, so I could get an apples to apples comparison. Minor differences to the car are I now have 3.15 gearing instead of 3.42 gearing. So the runs are up to 140mph instead of 130mph previously. And of course the 3.5" DP vs. 3" I had previously. In addition to the MOTIV Kit the car is running a BMS Fuel Rail kit, Fuel-It low pressure system, JB4 for tuning, etc, etc.

A few dyno charts and logs are attached. In addition I posted the a dyno from the last run I did on the FFTEC kit with the same tuning for context. I ran the MOTIV kit up to 27-28psi today, but from what they tell me, this thing will hum along just fine at 33-34psi. I hope to find out down the road. I decided to stop at ~630whp today as I noticed an odd O2 sensor variance which I think should be addressed, and timing drops started to creep in, so I'll need to resolve both of those issues before I really crank it up. My ulimtate goal with the setup is 700whp.

Outside of the numbers, the spool of this kit is pretty impressive for the size of the turbo. It spools just as well or maybe even a little better than the smaller precision 5862 in a twin scroll format. I've noticed my exhaust is now louder. No doubt due to the reduction in overall piping to absorb sound. Probably a good thing from an exhaust flow and weight perspective although I do like the car as quiet as possible. So I may go up to a larger muffler soon. I should also mention the kit comes with a revised poly motor mount which does transfer a little more vibration to the chassis than the OEM unit. Not too bad but worth noting.

We'll continue working on the project and will post updates as we have them

Awesome numbers!!

Dat spool!!!!!

Love this kit....

Would be nice to see one of these with a head that could handle 7500-8000rpm. Beautiful curve.

It's not just the cylinder head man, you'd have to build the bottom end as well! In addition, you'd have to revamp some of the systems to accommodate for the extra RPMs and increased demand in pressured fluids... Oil and such... these aren't very friendly engines outside of their comfort zones.

Mine is in the shop getting installed now with tons of other goodies (LSD, Clutch/Flywheel/etc) - can't wait!

I like how Terry explains stuff so well. That curve is legit too.

Call me crazy but my car spools faster than that with same kit lol!

Street pull log vs dyno log it might differ a lil,more load while driving on the street but not much

Very impressive results!

Gzim pretty much nailed it. Dyno testing will not load up the engine like doing road pulls will.

Terry's very thorough and objective testing(as always) is very appreciated. The JB4 is proving to be an invaluable tool and is only getting better.
