- Trigger systems, 3D scanning and sequential gear levers. Let’s get stuck in…
0:00 - Introduction
1:00 - It’s 3D Scanning Indoors, with Zac
7:09 - Sequential Shifter
12:06 - Nissan Optical Cam Angle Sensor
19:48 - Outro Bro
In this episode, the national man of many talents Zac runs us through some of the equipment used to 3D scan some of the key components of the GT86 which will allow us to do more data analysis in the future to help dial in and then refine the setup. As well as this Andre runs though why we're going from our Motorsport Design Systems single lever system on the TTi GTO 6 speed sequential to a custom dual lever setup, despite the team not being a huge fan of dual levers.
Lastly, get a rundown on why the factory Nissan 360 degree optical trigger sensor is not ideal when it comes to performance engine builds including the huge amount of issues it can cause your tuner and engine, as well as how the Mazworx SR20 trigger kit alternative we use is different.

This is great! CZcams needs more good sr20vet builds
How abt a b14??
Another great deep dive into your race car development! It was awesome to see your “new guy” calling in some heavy hitters and applying pro race team development tools to your build. Laser scanning, CFD, and kinematic chassis modeling! More of this please, it’s all right up my alley! It was also interesting seeing how you implemented a solution for the factory cam based timing system. The 60-2 reluctor wheel should improve things quite a bit. Nice looking parts from Mazworks as well as those motor sports grade magnetic and Hall effect sensors! The shifter looks like it will make things more solid for the driver as well, too bad it took a few iterations to get something you’ll be happy with. Such is the journey of car development, So much great info in this video. I’ll definitely be giving this one a rewatch or two!
Nice to see some computer added design 👍 just recently had my DTC box and sr20 CMM to make an adaptor for for the dual Clutch. Not sure about your air intake but the rest looks tits boys. Love the build 👍 and yes this car suits the SR much better ha ha ha
Continue leveling up guys, where learning too🙌
We can also use MAP to avoid wasted spark technique as in the intake stroke the pressure in cylinder drops that is read by the MAP with a voltage so basically we need to have ignition only after that, I believe there can be a strategy made on it other than using CMPS sensor.
Great show guys. Thanks for documenting this process
Glad you enjoyed it!
So informative, like.. I bet if he sold an online course it would sell like hotcakes. More than these fake business gurus running around. If HP Academy utilized an online learning platform to teach, no doubt future performance shop owners would say 10 yrs from now that they learnt everything just by watching HPA
This is awesome!
In the engine clips it seems the crankshaft seems very out of round? Looks very concerning the way the pulleys are moving around.
Another idiot comment. Why would they use a crankshaft that is out of round? Show us how you would correctly video record to show that the crankshaft is perfectly round and correct? Dumb comments need to be removed ASAP.
Things have gotten serious

I was wondering where he went.
I love seeing all the stuff you guys do!
What was that 4th pin you were talking about in the connector for the cam sensor? Shield drain? What is that?
It’s common to tie the shields of higher frequency signal cables to ground at both ends of the run to reduce possible noise from other signals and RFI.
The engine speed and position sensors are run in shielded cable to protect them from electromagnetic interference. The shield then needs to be grounded (only at the ECU end, not both) to drain any noise to ground. This ensures the integrity of the signal that the ECU receives - Andre
High Performance Academy
Ahh, understood! Thanks for the reply
Whould you talk about AFR and spark time used in sr86 please?
Sure, no real secrets in this build. Currently it's running a pretty conservative tune with ab out 22-24 degrees ignition advance and 0.78 lambda at 14-15 psi - Andre
I wonder if blocking the coolant outlet port from the head had anything to do with the suspected air pocket/ cooling issues you have had? Also curious why you opted for the blanking plate and not the normal style outlet Taarks or Mazworks sell for the ve?
Some of these vids lag a little behind development and we're running the Taarks plate with a Bosch fluid temp sensor in the head for coolant temp. This is a pretty well trodden option so I don't expect this is related to our current issues - Andre
Sorry, I know you said it but I can’t quite make out the name of the sensor brand. Thanks

Thanks guys
The two sensors are from Milspecwiring.com, however the entire kit is sold by mazworx - Andre
Since you guys have a sequential gearbox anyway, are there any plans in the future to switch to a paddle shift system?
Yes, it's a consideration. I added in the required wiring for a paddle shift system when I designed the wiring harness - Andre
Running 650 hp on at stock block?
We stopped tuning just below 600 whp so call that perhaps 620 ish flywheel hp. There's more in the setup but we don't need it for now. The reality is that the higher power will only be used as a push to pass system. Most of the time we will be circulating at 400-450 whp which is well within the capabilities of a non-sleeved SR20 block. We of course do have aftermarket JE pistons and k1 Technology H-beam rods though - Andre
@@hpa101 I am thinking about picking up one of classes. On rebuilt SR20. 😆🤔
The SR20 build is in this course here: www.hpacademy.com/courses/practical-engine-building/ - Taz.
Some f1 teams are watching the 3d scanning part, extra hard
I'm not too sure the F1 teams are regular subscribers to our channel at this stage 🤔- Andre
@@hpa101 Maybe Formula SAE?
Uh, they've been using it for a couple of decades - it's actually quite old technology.
Why would Nissan have specified 360 teeth? Seems way over kill.
More teeth does improve the resolution to the ECU so that it can more accurately account for changes in engine speed. This is more relevant at low engine speed when there's more time between tooth inputs. In reality though, you're right, 360 teeth is overkill and at least in the aftermarket causes more trouble than it fixes - Andre
First!
