PorscheDoc's 951/L33 Build

Nice build Doc, it's even orange like mine

You may want to brace the DMC unit as the entire firewall will flex when you apply as much pressure as you will be. Take it from me, my fire wall was flexing as much as 1/4".

Thanks. It is braced as you can see in one of the pictures above.

I see that now, I was looking at the pics on the first page.

Nice clean solid monster creation. Congrats!

Couple of track weekends breaking the car in. Still need to make some adjustments to the brakes, and it is time to rebuild the track weary suspension, so that will be taken care of in the next couple of weeks.

Running with a pair of Boss 302's. After lighting the front brakes on fire from the master rod being a bit too long, the rest of the weekend was uneventful.

Our 944 SP1 sunoco car in the background. One wheel up, the suspension definitely needs some reworking.

Then we headed to Hallett for some fun a few weeks later for a track day with a bunch of friends. 968 wing will have to go, just not enough downforce in the rear. Coming up over the hill between 1-2, 4th gear hazes the tires going over the rise, lol. Will put my front splitter on and a standard 944 wing in the rear for the next event.

My wife put some laps in as well, as was fairly comfortable with the car, so that was good. Hopefully will have the escort cups installed and a little better aero for MAM in a few weeks.

Last time I went to MAM the parking lot was underneath almost a foot of water

Lol, when it flooded 2 years ago, we had driven up to south dakota to pick up a race car. On the way up, the flood waters were at the side of the interstate in Omaha. 8 hours later coming back we had to take a detour around Omaha because the interstate was closed to flooding. We stopped at MAM and ran the weekend there, it was like being the orchestra playing on the deck of the titanic as it was going down. We watched the water slowly creeping toward the track throughout the weekend. Made it out just in time on Sunday. After the flood subsided, we ran on the track that following spring, and thankfully due to a mild winter, there was no freeze/thaw and the track was fine. That parking lot has always been sh$% (odd for an owner who also owns a concrete company). This year the parking lot is really pushing up due to the soft ground, we ripped a starter wire off a spec 944 when running over the top of one of the "volcanos". The track surface is intact, but the corners are pretty bumpy. The ground is just so soft right now. For some reason we are headed back up in a few weeks, lol.

You're a glutton for punishment. We had to drive around the ponds that were mid apex. Ended up having to bleed the brakes in the parking lot and tried to find a somewhat dry spot. It sucked. I won't forget it anytime soon tho, just like that flea bag hotel we stayed at in Hallett. By far the worst I've ever been at.

haha, the budget Z in Cleveland? We always make the drive back to sand springs/tulsa when at Hallett. The drive sucks, but the rooms are nice, plus then you have some decent meal choices at night.

It was during One Lap and to stay at Tulsa would've added 80 miles to the drive. As it was we got lost and didn't roll in to the hotel until 3am.

Next time I go I'm definitely staying in Tulsa!

That is kind of like the one review I could find for the motel in Byers when running HPR....it said something to the effect of "Got stuck here in a snowstorm when they closed the interstate one winter....if I had to do again, I would have rather died in my car...." We make the trek back to the airport hotels when there, lol.

Yeah, that motel in Byers is pretty bad too from what I hear. It doesn't make sense for me to stay near the airport when I go to HPR, another 20-30 minutes and I'm home, so I just come home.

You coming out to HPR this year? I've got my 948 up and running really well...

We were going come out for the club race in august, but that is the same weekend the grandam guys will be running at the new Kansas speedway course, so we are going to stay to watch that. I think the only time we will get out there will be in September for the Chump Car.

LMK when you're going to be here...

Where do you get the tubing for the hood pin extender support thingy? LOL I need to figure something out for mine.

Well, over a year on track and a couple thousand track miles and no issues to report with the conversion.  I had a leaking TPC oil pan from the get go that I just ignored last year.  Super slow leak, so was only an issue when it sat for periods of time at the shop. It was at one of the welds on the sump area, which I finally found last week after grinding away on the pan after spending some time pinpointing it (when the car would sit for a month at a time it would drop a large puddle of oil under the car).  A quick zap with welder and all was better with the world.  Not sure why I put it off for so long, lol.  Lack of brakes is getting better.  I have changed to turbo S front calipers and played with different masters and the car is starting to stop like I want it to.  Other than the oil pan leak, I have just changed oil between events and that has been the extent of maintenance on the car.  I did add a front mount oil cooler for oil temp control, but no big deal there.  

This spring time was spent on aero.  At Hallett I could haze the tires in 4th going over the hill between 1 and 2, so that was a major concern.  Called up Brooks motorsports and we remedied that issue.  Along with a 3-4" front splitter I built out of Alumilite, the car has never been so planted or cornered so well before.  Car has no issues getting past 600hp GTR's and staying with GT3's (other than in the braking zone, lol).  So far it is doing everything I wanted it to.  Low maintenance, low stress, yet fast enough to harass a few cars and raise eyebrows.  I watch all the guys working on their cars at the track, and I am usually like...."well I guess I could check the oil for something to do"
 
I've played with tire setup, running 275 square and also 245/275 stagger. Might be old tires, but the stagger setup is just as fast if not faster (not at all what I expected), which is what we have also found running square/stagger with the spec boxster sitting next to it.

Sounds very nice! I'd love some details and pictures on the splitter you made. Aero is something I want to work on this coming winter. The GT3s kick my ass.

Not much to it.  Alumilite comes in 4x8' sheets like plywood but is basically 2 sheets of aluminum with a honeycomb center.  Stuff is super strong.  We get it at our local aircraft supply store.  Sheet is about $100, but we get multiple splitters out of one.   Cut an approximate size for the bottom of the bumper (cut it wide obviously), bolt it to the bottom of the bumper how ever you see fit than with a jigsaw upside down from the bottom, make the contour to the shape of the bumper how ever large you want it.  Super easy.  You will need to use some turnbuckle supports like I did on the orange car, or you can go the cheaper route and just use cable and crimps with some small eyebolts from the hardware store like i did on our chump car.  I think the cable is the better route as that way if you punch something from the bottom, the splitter can flex up without shoving turnbuckles through it or your bumper.  Turnbuckles are fricken expensive!  If you want to lower the splitter, I would cut multiple sheets of some plywood to the contour of the bumper where the splitter mounts, stack them, then bolt the splitter to the bumper with them inbetween. Or something to that effect. My car is very low, but just bolted to the bumper as is makes a huge difference. Even on our chump car with stock ride height, it is an amazing difference in cornering (On the chump car we use a nascar style spoiler" out of alumilite bolted to the rear rubber spoiler....that car is glued to the track on street tires).

Shot of the alumilite construction.  This is some super strong stuff.
