Re: Oops - 2 days ago
It appears that after re-reading the description of my new car that I might have made several ..ahemm typos? I guess Roger does know me after all. OK, it is a 981. Beyond that, I won't say anything for a couple of days. A few of my Boxster Fun Run buddies are having a little contest right now. Since some of them frequent the board, I don't want to give anything away. For anyone thatby MikenOH - Main Forum
Track update - 3 days ago
Just finished a 3 day event at Mid-OH with Grant's group--NNJPCA--and the car passed with flying colors. Oil temps never exceeded 250; 240-245 was typical while running 20 minute session in 80 deg. temps and, of course, the temp gauge never moved over 200-- amazing don't you think Had hoped to finish the year on stock pads but I think the car just has too much top end and/or braking areas forby MikenOH - Main Forum
Re: Could be due to the resonance flap opening - 9 days ago
n/t That sounds about right on the 981S. Regarding the 991/981S 3.4L comparison, if you look at the 3.4L 991 torque/HP curve, you can see Porsche did things differently on that motor vs. the 981S--smooth torque curve vs. drop off, providing 20+ ft.lb of TQ and 35+HP. Different induction system, larger exhaust header? Sure doesn't look like an ECU tweek.by MikenOH - Main Forum
Bruce--I noticed something similar on the 981 - 10 days ago
At about 3000 RPM the car seems to stumble a bit which coincides with a dip in the engine torque curve; there is no such drop on the 991 but a substantial one on the 981. Click on the technical spec footnote on the HP rating and the HP/TQ curve will show up. http://www.porsche.com/usa/models/boxster/boxster-s/featuresandspecs/ It peaks around 2500 and falls off to 3500 rpm, then recovers toby MikenOH - Main Forum
Re: Maybe because some of us just want a nice car to get us from A to B... - 10 days ago
Driving a manual is a preference now that performance is no longer an advantage. It is more akin to using manual focus vs auto focus on a camera, manual exposure/shutter speed vs program mode, etc...a skill to be sure, but no longer represents higher quality results for most and usually less optimal results for many. True, but then again the question is why people choose to buy a Porsche.by MikenOH - Main Forum
Re: That's a lot of front negative camber for a stock car! - 12 days ago
Yep---1.75 neg F camber on a stock Porsche is a big number--we'll see how it benefits the tires both on and off the track. The last two alignments have included just a hair of toe in-.07 on each side--which supposedly helps aid in stabilizing braking at high speed. Had the same thing on the 987 and didn't notice any excessive wear to the inside tread. First reaction is that the steering isby MikenOH - Main Forum
Just had a track alignment done.. - 13 days ago
On the 981S with the SS suspension he was able to get -1.75 negative camber in the front; the 987 with PASM could only do -1.0. This should add some tire life--I hope. I went from a factory setting of -.9 (F)/ -1.5 (R) to -1.75 (F) / -2.0 (R)--with a little toe in in the rear.by MikenOH - Main Forum
Re: Torque spec - form the horses mouth - 15 days ago
I got the TSB last night. There is no change to recent 96 lb-ft specs. All new 997/987/991/981 effective 2012 changed to 118 lb-ft / 160 n-M There is no ratonale given whatsoever. Many dealer service managers are clueless about any and all of this. Apalling. Grant So, if you had a 2011 987 your torque setting is 96 lb-ft and if you have a 2012 987 it is 118 lb-ft..; hmm.....by MikenOH - Main Forum
Forgot they aren't in all sizes - 16 days ago
A quick search of TR showed some good pricing on the BS S-04 and Conti DW in Boxster S sizes. The S-04 tested out pretty close to the PSS , while the Conti has a reputation for a smooth quiet ride and good wet weather performance.by MikenOH - Main Forum
Re: In the grand scheme of things, 220 deg (oil) is fairly cool for the track - 16 days ago
Sounds about right but it wasn't a real hot day --low 70's. I'm going to use the coolant/oil data displays more next time out and make a note of the data.When I've been on the street the coolant stays remarkably stable while the oil temp moves around i've seen it as high as 235 deg. I'll probably change out the oil after the NNJ event and possibly go with that Lubro Moly 5-40 full synthetic-by MikenOH - Main Forum
Re: What coolant / oil temps were you seeing on the track? - 16 days ago
To be honest I had it on the tire pressure settings to let me know when I was getting above 40PSI--which was very helpful. The only time I had it on coolant/oil pressure/oil temp readouts was on my last lap of the afternoon session which showed something like 200 deg. coolant and 220 deg. oil temp. That 200 deg. coolant temp is amazingly consistent; you don't suppose..? I'll eventually get a cby MikenOH - Main Forum

Re: Wg and brake fluid - 18 days ago
I still have NT-05s mounted on 987 S 18" rims so they should work fine. After they are done I'm thinking the NT01s unless something else comes up. Finding tire 18" sizes that work on this car is tough; the 245/275/40 combo is in the PSM required window but that is it.by MikenOH - Main Forum
Re: Thanks for the report. I'm sure as you dial it in, this will >>> exceed your 987. - 18 days ago
I hear what you're saying, Grant. I didn't have time to change the tires out but will have them on with an new alignment and Motul 600 brake fluid for the NNJ event in two weeks and then see where it goes from there. The brakes didn't really feel too bad but higher temp fluid really does help. Also, there are substantial F & R brake ducts which I think help cool the brakes a bit better thby MikenOH - Main Forum
First track event with new car-- a few observations - 18 days ago
Had an open track day at Mid-OH yesterday and put about 1 hour on the track with the street tires/pads.Kept the revs down since I was a few miles shy of the BI period. Speed--amazing; it gobbles up pavement even when not in the peak HP range. Noise--the stock exhaust makes a great wail at even 1/2-3/4 throttle opening. Brakes--good enough for most of a 20 minutes session but better fluid andby MikenOH - Main Forum

Re: Please let me know. Nearly all Porsches since the late 70s have been 96 lb-ft - 20 days ago
The manual on pg. 212 says: " tightening torque for wheels bolts: 160NM (118 ft.lb.)" I'm thinking of doing 100 ft.lb--the dealer will have a tech at the event so we'll talk about it. I really don't want to over tighten because at the temps the brakes get on the track the rotors could warp. I've had new cars that have had one or two lugs loosen between delivery and when I staby MikenOH - Main Forum
Paging Laz--118 ft. lb. wheel lug torque setting on 981? - 20 days ago
I've got a track day tomorrow and after consulting the manual saw the rather high number for the wheel torque setting. When I put a wrench on the lugs they were all in the 90-100ft lb range, so technically they were all loose. I can see a few that might be low coming from the factory but all 20? Have you checked yours by chance? This number seems a bit high relative to the 987.1. I 've sent a texby MikenOH - Main Forum
Re: 987 - 981 measurements comparison - 26 days ago
Interesting info; significant area of cargo space lost behind the seats in the Cayman on the 981. On the 981 Boxster the major loss of space seems to be in the rear trunk--bad if you're a golfer--despite the fact the published numbers seem the same. Regarding front and rear fender height, our 981S with SS is at roughly 27.5"F and 27.75" R--say 13mm in front and 20mm in the rear. Lower fby MikenOH - Main Forum

Re: Autobahn USA! - 28 days ago
I have used that road several times in the last couple of years to visit relatives in the Olney area coming in off of 270. It's one of those amazing toll roads that looks like it took billions to build. Having said that the notion of the Maryland bureaucrats allowing triple digits speeds in that section in my view is as likely as men walking on Mars in the next couple of years.by MikenOH - Main Forum

Re: Ran the rebuilt boxster at SCCA Solo today, my first drive "in anger" - 7 weeks ago
Glad to hear it's back on the road. It will take a little time to get used to the suspension changes. When we got the 987--replacing the 986-it took a lot longer than I thought to get used to the handling in a track situation and I expect the situation will be the same on the 981. The traction levels were much higher, there was PSM to contend with and the steering had a different feel to it.by MikenOH - Main Forum

Is the N designation important....? - 7 weeks ago
Oh, boy here we go--get out the popcorn . Regarding the PS2, I've had them with the N2 designation and they were great tires.

Re: NBC: I lost all respect for Sebastian Vettel today - 8 weeks ago
I'm curious to know what caused your lost of respect. His driving or his attitude and post race comments. About his driving, the way I saw it, he was the fastest and told the team he was. He tried to overtake on a very traditional part of the track (straight with DRS support), but was roughly push to the right by Webber. I agree to a few facts in this case: 1- team mate should compete aby MikenOH - Main Forum
