How is tranny and diff holding up?
Is it time to develop a cooler for the tranny and diff?
Busy moving company into new building, zero free time to get to the dyno until we get out of boxes. Today was stuff like get the lobby metal work up, knock out another wall for Ryan's product development area, locate an A/C duct over Sean's office, etc.
No issues with tranny and diff. E85 tune feels a lot faster. We know from using this trans in the NC that it is good to 300 hp without adding cooling (remember this is NOT a delicate ND Skyactiv transmission, Fiat went with proven NC transmission). To put it another way, I still race our 2007 NC Miata with 320 at the wheels, no fluid cooler for that trans so I don't expect it will ever be 'time' to develop fluid cooler on the Fiat 124. With the NC an air scoop was enough for our extreme 'NC LIGHT', with scoop shown one page back on the Fiat 124 compressing more air on the engine cast finned oil pan and trans the temps are holding steady for both engine oil and trans at our SCCA HOT Summer competition days. Will get that scoop to market in the next few months. If we can be happy on heat levels with simple air scoop then no good reason to do fluid cooler that adds massive costs and complications, additional points of failure, etc.
