That is true but that might just be more a Toyo thing than a MX-5 thing. Not many guys are running the Toyo's with S2000s that I know of. Matt, do you have any idea what your 60' times are like?

 

i experienced exactly what you concluded marc.

i was fortunate enough to drive both eric simmons' 06 miata and dave corsaro's (njdrive's) cr after driving my ap1 this past weekend. eric's car is very well prepped and dave's car is simpler than i thought. there's a lot of time left on the table with no flash and could use more dialing in handling-wise. my ap1 has a front bar, front camber, and motons.

dave's cr was a bit surprising. it felt like it accelerated slower than my ap1 but i'm guessing feeling quick and being quick are two different things. it definitely had dramatic power oversteer tendencies when you get back on the throttle (and this car doesn't have flashpro!). this car is very stable in transitions. i swore i was going to be significantly slower as i crossed the line. i managed to beat his best by .5 seconds and ran my fastest time in this car (meanwhile, i lost a lot of time when i got the cr sideways under power). this must've lit a fire under him- he subsequently ran faster than all of us on his last run.

eric's miata was easy to drive fast. ohlins + os giken = awesome. putting down the power was undramatic unlike the cr. tons of lateral grip. it did exactly what you told it to do. extremely stable and predictable. i was .3 off eric's best having never driven a miata before. i'd describe it like jreyega did about his ap1. almost boring but quick.

eric ran his best time in the one run he took in my ap1 (faster than my own time in it). he loved it and wants to drive it again this weekend. we couldn't get dave to drive mine.. i would like to see what he thinks of it compared to the cr.

after driving all 3 of our cars back to back.. the way they are setup now, they're very close in performance. the ap1 is the most enjoyable to drive for me.. but i feel it doesn't have the potential of the cr. if i could justify double the cost of my '01, i would pick a cr hands down. i'd set it up with the big ankeny bar/flashpro and do whatever else it takes to put the power down early.

2 Ways to skin a cat! Thanks for posting Bo- err ... Rob!

I can see how downshifting may be more prevalent in STR, specifically because of the street tires. With the lower cornering speeds (when all of the grip in the car is demanded, like in the nationals sweeper/turnarounds) I can see how 1st gear would be necessary, as it clearly is, though there were a couple of downshifts you made that I wouldn't have, it seems to be definitely required to go quick in an AP1 STR car.

Maybe I'll come play in STR in a few years with an AP1. Need to run a CR in BS first though.

Wow awesome post!


I've been test driving cars (stock ones), and I also noticed that the ap2 acceleration feels much slower than AP1. I don't know why. Also my shifts felt super slow in the ap2 - i think there's some computer nonsense slowing down the shifts. Anyone else felt this?

I hope to be able to drive them both in autocross trim to see how they compare that way. This weekend I'm co-driving brian singer's AP1 at warminster - maybe I'll meet you there if you're going.

 

My setup is very similar to Dave C's... I have similar spring rates, the same front bar (but we run it on different settings), biggest difference suspension wise is I have more front camber and no rear bar.

Power wise ive got all the bolt-on's just need a VAFC

 

The delay your referring to is from the clutch delay valve.

 

Or the heavy flywheel. I think that's more noticeable than the delay valve.

 

i'll see you there. simmons is designing the course this weekend, he said he's going to keep us out of vtec haha.

Are you talking about stock for stock? Or tuned vs tuned?

The AP2 accelerates significantly better, especially in the lower speed ranges...even my butt dyno said so!

I just find it funny. Driving the AP2 feels like driving a big block AP1 to me...

 

stock for stock.

I'm more interested in tuned for tuned, but have no experience with it so I have to make do with what I've tried.

I've driven a couple AP2s....they honestly feel about the same as my ITR in terms of acceleration - but they should be significantly faster. I only drove one AP1 though, and it really put me back in my seat (or felt like it did). Driving more AP1s to make sure that's really how I felt will be useful here.
