Anyone have a gearing calculator website?
I rewired my JDM CRX SIR cluster to display MPH.
Last night my brother and I took it out for a test drive.
In 5th gear we pulled 7800+ rpm and the cluster showed 142mph.
The car has 205/50/15s, and a USDM ITR transmission with USA spec. 4.40 gears.
I wasn't watching the tach as closely as he was but he said we almost touched 8000rpm.
Are there any websites that have a gearing calculator that can convert my MPH to RPM to see if we were actually going that fast?
Before anyone calls BS, '89 HF, no wing or ground effects (slows you down), GSR engine I/E/H and no other cars on the expressway for that half mile.

They don't have any hydro trans gear ratios listed but you can probably get close with the YS1
