How dyno numbers are utilized by ITAC

[JeffYoung]

Maybe Steve E. can weigh in on the Irish Mike ITS E46 car. I vaguely remember it, but I think he converted it to an ITR car after a year or two. I don't remember it (the ITS version) running away from the field at Roebling though.

in 2008 the then ITS 323 was leading the SIC over MVS when he spun entering 4. MVS went on to win in his miata (Andrew C won ITA in another ISC miata). I think the following year Irish Mike went to ITR with that car.

it wasn't a slouch but I would have expected it to pull a miata harder in a strait line. no doubt Irish Mike had it tuned as close to perfect as he could, so it's safe to call it a 9/10ths car, minimum. I remember his justification (to me, when I asked) for going to ITR that the 323 was too slow. I'm sure the actual response was much more colorful.

As you know, that's a Miata track. I've seen the ITS ISC Miatas lose exactly once there -- to John Williams' 240z. I thought John still had the ITS track record, but looks like Mike has it now (still all very close).

Hard to gauge that track by times though, it is so temp dependent.

I was at that race between Irish Mike, MVS, and the ITR red BMW Z. that was an intense race. I believe they were constantly in 19's (could be wrong, but I remember they were on pace with our FP times that was inthe 18's.) For what it is worth the faster setup of the MVS ITA Miata (better splitter and new motor, and pre-roll at driver school) With Andrew C driving was about 1-2 seconds a lap slower than the ITS cars mentinoed.

so mathmatically

ITS BMW > ITS Miata (at miata track) at sebring Irish mike won.
Both ITS > quick ITA miata with good driver
quick ITA miata > ITA miata at last race at RRR
ITA miata at last RRR race>ITS TR-8

John Carter drives that ITA ISC Miata very well. He's not lacking for power at all though. He could stay in my draft at Roebling. The one place on the track -- the front straight -- where I should be able to put some distance on him, I could not. The rest of it, that's Miata heaven. ITA Miatas have won the overall there several times. I was lucky to beat him once back in April and thought I had him on Sunday in July, but he made a great pass on me in 1.

I don't think an S car has officially been in the 19s at Roebling. Track record is 20.5 (Irish Mike) and I think Charbonneau and Williams have been in the 20s. Best I've done is a high 21.

Not saying that John doesn't drive the heck out of the car. That car has had some rough times. (it was rolled at the double school last year). It has a good motor, MVS puts out a good product. My point is that Mike in the BMW on a miata track was toe to toe with the best in ITS miata. Both with great drivers.

John's car has a VERY good motor.

I am certainly not saying I'm among the best ITS cars to run at Roebling. I'm definitely one rung (at least) below Irish Mike, and Andrew, and Mike and Kip, and John Williams.

But I think I have enough time up front at the track, and in racing with the Miatas, to think that a well prepped, well driven ITS or ITA Miata is going to very, very hard to beat there. Can be done, certainly, but that track -- a big long momentum track - is perfect for that car.

The only place I have an advantage, or a Z car, is the last 1/3 of the front straight, and even there, Mike at ISC has done so well with power development that this disadvantage seems to have disappeared.

Just confirms that there is always development to be done.
