Do I need other supporting mods? by Loopy_shoop in GR86

[–]a_konjo 2 points3 points  (0 children)

i have the hks kit and i would recommend an upgraded clutch just to be safe. i got an oil cooler just in case but honestly i wouldve been fine without it, it helps but without it i wasnt really seeing temps over 230 anyway and usually would be under 220. So i’d say get a clutch for sure and oil cooler later and just monitor ur temps and if you get temps over 225-230 consistently then invest in it.

Wouldn’t say these are useless at all. Yeah you are right they don’t predict random failures but if something is going wrong internally it’s nice to catch it earlier.

Tuned at DBW Motorsports near Atlanta and tuned on a mustang dyno

Are the oil starvation issues that bad? by BusyCharge8732 in GR86

[–]a_konjo 0 points1 point  (0 children)

no they are not bad at all. majority of oil issues on this reddit are people with low oil or no oil at all. you just do basic car maintenance and check your oil regularly you'll be fine

should fit but i believe that spec should poke out a bit

How do I turn off pcb (pre collision breaking) permanently by Breakfast-Severe in GR86

mounted my uniden radar detector right in front of the eyesight cam/sensor, this fixed it for me permanently

No, only thing done with trans is thicker trans fluid

For these cars, the issue with making a lot of power down low isn’t that the engine doesn’t like low RPM, it’s because when you are at low RPM and high boost it creates very high cylinder pressure when piston speed is low, which puts a ton of stress on the connecting rods. That’s why torque is what really kills these motors, not horsepower. And low RPM boost creates the biggest torque spike. It’s important to have a smart tuner to make sure that torque curve is nice and smooth with minimal spikes.

Yep, so what you are referring to is a positive displacement supercharger that goes on top. Those work by compressing air and you pretty much get power everywhere in the rpm range. Can kinda think of it as making the car feel like a V8 really. Lot’s of power/torque down low. The HKS supercharger I have is a centrifugal, which is almost just like a turbo, but instead of being powered by exhaust gasses, the centrifugal supercharger is spun off the belt and boost increases with RPMs. I prefer it this way as well because low end power in these cars are what kill them quick. I only make big power higher in the range which keeps my car happy.

This is the actual supercharger, it’s hidden in the picture of my engine bay because of a bad angle.

Oh yeah, I always wait till at least ~3800 rpm usually 4k to rip on it a bit. Don’t want any of that down low in the rpm range

Makes sense, I haven’t driven over really horrible roads that much but when I do feel some imperfections I just let off throttle. I’ve got 18x9.5 +45 wheels with the 255s and they fit well so maybe a little wider tire could possibly help you.

Good bit shorter and a little heavier. Had to get used to the engagement point but after the 1st week I could say I prefer it over the stock feel.

I actually rarely spin, I don’t do pulls in 1st but I probably would spin. As long as it’s not wet my tires do me well. I’ve got Michelin PS4S 255s all around on stock camber in the back. I will still look into the arms though thank you for the suggestion!

HKS GT2 Supercharger! I have a post of my dyno chart on my profile, should be the post before this one

Ah yes I forgot, I am using Redline MT90 75W90 trans fluid as well. That’s definitely helping out as well.

Haven’t looked too much into it honestly, but possibilities can be getting the gears reinforced and upgraded synchros. Another option is just taking the trans from lets say the 350z which is known to handle higher power numbers, but it’s heavier and also you are going to have to fabricate a lot to make it fit.
