Super looking car.

How the hell you managed 28mpg, I do not know!

I do :-)
I think the mileage AFTER the IMSR was better than before, right Gary? If so thats what we normally see.

It was great working with this car, it is so damn clean and well cared for! I drove it close to 400 evaluation miles after the procedure and its one of the best driving Boxsters I have seen yet.

The IMS bearing was in GREAT shape, showing very little signs of issues, it hadn't even reached the point where we start to note stages of failure. Gary's car was certainly better than most and much better than the car that arrived the day after it left that came in from Louisiana that was at Stage II failure already but drove in under it own power. We'll be finished with it today.

The trip Gary took is AWESOME and made possible due in part to our location in the mountains of NE Georgia just down the road from Deal's Gap.. Most every owner that drives down for a procedure ends up hitting the Dragon on the way home!

Gary,
Thanks for the business and believing in what we have created enough to spend the time and money to outfit your Porsche.

Really? What kind of "increase" in mileage do you see? Are you saying that the IMSR itself produces a noticeable improvment in gas mileage? Or the combination of new RMS, clutch, underdrive pulley, and a low-temp thermostat for good measure did the trick?

Also I'm curious why "400 evaluation miles"? Was a computer hooked up during this drive? Was the car "tuned"? It kinda/sorta sounds like "Freeis Bueller's Day off" to me. I you drove my car for 400 miles I would be pissed. Somebody would be walking with a limp.

Generally those who have us do this procedure WANT us to put miles on the procedure before they drive several hundred miles home.. We always ask anyone who is going to have the procedure done if they have objection to me driving the car for at least 200 miles, if they do, then I won't do it..

Yes, we have gear that is used in the car to evaluate it both on the dyno and in my daily commute of 83 miles round trip per day. We can't drive all the cars for this extended period because their owners are waiting for us to finish, or because the car has to make a scheduled date for a return shipment home.

This is a major service, lots of things are taken apart and we must ensure they are correctly put back together without any oil leaks, weird issues, noises or even something as simple as clutch chatter. I'd much rather have ANY issues show up while the car is in my hands than the owners hands so they can be noted and addressed before the car leaves.

Because of this we attained and have maintained a 100% effectiveness rating with the IMSR procedure, if I did not drive the cars for this many miles I know of at least three that would have had an issue on their way home after the procedure.. two were slight oil leaks that showed up after the dyno evaluation, but within the first 150 road test miles. The third was a bad pressure plate that was bad out of the box. Not everything works perfectly every time, thats why we have to test what we do.

I have a firm policy, if someone doesn't trust me to drive their car for evaluation, they should seek out someone else to carry out their work. I have over a dozen cars, three of which are Porsches, I don't need someone else's car to go have fun in.

We only do things once.

As for the MPG increase, typically the IMSR will show a tad more MPG after it has been carried out and after the new bearing's break in procedure.. It always doesn't do this, but there are some good instances of it.

I know I wouldn't want it taken just a few miles and given an "all clear" before diving 1k miles away from home. Of all the miles on my car, 200-400 is but a small drop.

Banana S · 08-17-2010, 08:19 PM

Amen to that. After seeing one of Jake's other cars, I wasn't too worried about him ragging on my Boxster.

And I was much more relaxed on the drive home knowing that the "shake down runs" had already occurred. (I look relaxed in that second picture, don't I?

)

Thanks for the compliments on my car, Jake!

Jake Raby · 08-17-2010, 10:25 PM

Yep, you look relaxed!
Like I said, if someone doesn't want me to put the extended miles on the car, then I will not.. But at minimum the car is being driven 100 miles, if not it leaves my facility as a possible liability.

"As for the MPG increase, typically the IMSR will show a tad more MPG after it has been carried out and after the new bearing's break in procedure.. It always doesn't do this, but there are some good instances of it."

Not to hijack the thread, but what is the new bearings' break in procedure? I had the procedure done and my mechanic didn't mention anything about a need to "break in" the new bearing.

FWIW, after picking up the car, I took it easy going home and the next day I went on a road trip to Western Maryland (about a 3 hour drive from Baltimore). I took it easy most of the way, but i did get up into the 90s the further i got into the mountains. Top down all the way, beautiful. (Maybe that's part of the procedure? hehe)

What was your improvement in gas mileage - 3, 4 MPG?

I haven't noticed anything dramatic, but i haven't really been monitoring it either. I am due for a fillup so i will get back to you after a few tanks.

It was a rhetorical question.

AARRGGH, I hate rhetorical questions. I get enough of that crap from my boss. I don't need to get it here too.
