FR-D AE86 + 8.5T
Yes I know there's a 4AGE in the engine bay, but due to a lack of competitors in this class, Ive Upped the power.
Thus is what an engine swap looks like in an FR-D.
17.5T usually turns about 15000RPM. With reduction gear sets in my FR-D dropping Final Drive to about 10.5 the throttle range at 10% is only 100Rear Wheel RPM to 100% maxing out @ only 1000RPM. this usually results in scale experience straightening mid corner and needing constant clutch kick to keep the drift.
so how about 300% power increase.
8.5T usually turns about 35000RPM increasing throttle range at 10% to 250Rear Wheel RPM to 100% maxing out @ around 2500 RPM at the wheels. This usually results in non-scale AE86 experience, but it means I can run with any other 1000hp chaser. hehe!
to get back to AE86 Power levels, I simply drop EPA or ESC forward speed back to 40% The smoothness of the motor allows a near equal result.
I run this machine on slippery concrete, so 100% throttle is actually too much anyway. I usually settle somewhere around 1500 RPM at the rear wheels for a balanced drift @ around 60~65% forward speed.
Having extra power means you can always go down. but with a 17.5 or 21.5 it's harder to go up in power as the gearsets are hard to get to in the FR-D.
All good. Big angle now NO PROBLEM!
