MR2 and 4age powered acrs

Efrain, that letter is not public info, though if the author wishes to share it himself that's up to him.

I'm 99% certain that the AE86 and FX16 WILL be adjusted to 20% just like the MR2 (so 2285 and 2240). you don't need to resubmit the 4A-GE data, we're well aware it's the same motor in all 3 cases. I'm really upset we didn't get that done before the realignment started.

This is good news... Might have to dust off the Ae86... its been refreshed and "lying in wait" for the last few years....

In changing weather conditions there were two 4AGE powered cars in the top 4 (ae86 and aw11). No torque finally paid off.. though when it dried out...we went backwards in a hurry.. but it looked cool for a little bit. Haha

Locally we only have two very short tracks(1.4 & 1.5 miles) and with a 5.37 final drive make the AE86 competitive as many of the competition either don't have it available or don't think they need it

Just out of curiosity, if you guys weren't maxing out your speedometer have you considered changing your final drive. There are now more final drive options that could allow you to be much faster out of turns and since the free ecu rule you could drive on 5th until the brake-in(8,000rpm) point.

Thanks,

yes, we know we could get faster in the short run with higher numerical final drive (I think that's "shorter" - these colloquialisms never make sense to me)

Steve "Quadzjr" has a 4.7 in his car and there are more of those floating around which we will snatch up when we can. but Daytona is one of our local tracks, along with sebring and Roebling, all of which are pretty high speed... at roebling we actually prefer the factory FD over the 4.7 as there are fewer shifts and less time in 5th. going MUCH shorter (right?) would make 5th tolerable and could put us back down on shifts/lap but then we're in 5th on a C50/52 box which is known for popping out of 5th as the shift mechanism doesn't have enough positive engagement of the gear, and shaft thrust will actually disengage the selector. the C52 was vastly improved and you can build to offset this problem but I've not been able to make it disappear completely.

I haven't done the math but the C52 transaxle case will be the limit on gearing, ~5:1 is probably the best we could do, maybe 5.1:1. then you throw in the weakness of the 5th on the same box and you have a dilemma. remember that flat plane final drive sets are weaker than 90° ring and pinions most of the time and you start to get REALLY small on the drive gear which means a lot of heat and the box isn't built to handle that. the box sits right on the side of the engine, has little to no cooling airflow and no provisions to make of good use of what air it does get, and adding coolers for the gearbox is not allowed. so even if there's a physical restriction of >5.1 we might not want to go there.

but yes, we are aware of the physics of it.

I am pretty sure that either FWD or mr2 use the same FD and team M Factory has them available.

There are also FD for our beloved AE86 and also in Weir Performance alone with some LSD repair kits

Hope this make our 4AGE powered car more competitive even if that means repairing the transaxle more often
