Cory recently pointed out to me that it's mildly surprising, given how much I enjoy writing, and how much I pretend to enjoy working on my car, that I really don't do a very good job of sharing what I do to to it, so that others can suffer vicariously with me. With my latest exercise in futility, I thought I'd try to rectify that.

 

A little background on my car which may be redundant: It's a 2005 Intermeccanica. Henry built the car for me as a “coach” with no running gear, as messing with the engine and such is what I purport to enjoy. After delivery, I installed a 2110 which sported some of AJ Sims “best” (craziest) ideas. Those of you who've been around long enough to recall my ignorance, know that the entire thing was built around heavily modified 46 mm Kadrons, which were a complete disaster. In the end, I installed some Art Thraen rebuilt 40 Dellortos, a DTM, and an A1 sidewinder.

 

It was a fine engine, and should have kept any sane man satisfied for a long, long time. I however, am not a sane man, and by 2008 had contracted with Chico Performance for a short-rod (5.325&rdquo 2332 with nickasil cylinders, 44 x 38 mm valves, a bevy of cylinder head coatings, 48 Dellortos, a DTM, and a 1-3/4” sidewinder. It made 201 hp at the crank with a belt and through a muffler. To put it in the car, I built a really cool 2-1/2” exhaust out of mandrel bends that wrapped around the engine, and had an electrically operated cut-out before the muffler.

 

At the same time, I installed 911 motor mounts on the engine and transaxle. I built a pretty stout (heavy) steel “mustache” bar to connect the engine to the rear mounts.

 

 

Somewhere along the way, I installed AL Bivens wheels, and had NHS re-do the combo gauge to eliminate the fuel gauge and add an oil pressure gauge. Henry supplied a re-would fuel-gauge sender to trip a “low fuel” light. Also at some indeterminate point, I re-did the pedals with AL covers, a dead-pedal, and better spacing for heel/toe work.

 

 

In 2009, I installed a pair of grossly overpriced (and way-comfortable) Fibersteel speedster seats, and had the rest of my gauges re-done. I built AL frames for the seats that allow the seats to hinge forward. I had NHS recalibrate the speedometer to my actual tire size, so it reads true (with my GPS, and a radar gun), and had the tach re-screend and rebuilt for 8000 rpm. I installed CHT gauges on all four cylinders.

 

In 2010, I re-did the transaxle with a ZF LSD. At the same time, I changed to a gusseted AL rhino case, and went to a .89 fourth gear (from a .82). I also had NHS re-do the CHT gauges to make them look better.

 

 

I've been able to log about 10K miles in 6 seasons of driving (which is pretty pathetic)-- but in those 6 years, I weathered a recession with my business, built a house & a barn, married off all three kids, and had 3 grandkids born. Given as much time as the car has spent on jack-stands, it's not as bad as it could have been.

 

Which brings me to this year:

 

I've wanted to dry-sump the engine for a long time. I was reluctant, because this would require re-doing an exhaust I had built at considerable expense of time and treasure. Last fall, I hit a piece of the space-shuttle (or something equally large) in the road, and messed up one of my precious exhaust tubes pretty badly, so I decided that rather than repair what I had, it'd be a great time to start over and do the dry sump and a new exhaust.

 

And so it began...

 

Late last year I ordered and received a Bugpack 2 stage dry-sump pump from aircooled.net. Once I received the pump, I sent it and the mustache bar to Tiger from A1 to have a 1-5/8” short-tube header built that would clear both parts and not stick out the back of the car. It was supposed to take 3 weeks. At the 3-month mark (after calling every week, then twice a week, then every day, then twice a day), I got the header. It cleared the pump, but not the bar.

 

Rather than start over on the header (and wait another three months), I decided it would be a good time to make a better, lighter rear hanger bar for the engine. In a fit of hubris, I decided to use AL to save weight. This made the fabrication about 10x harder, since I don't have a spool gun for the MIG, and had to keep taking the pieces back to a welder to have done. Here are progress shots of the bar, from about mid-point to completion:

 

 

I built the exhaust out of mandrel bends and mufflers from Summit Racing. I've been reading a lot about exhaust tuning, and was convinced that the large primary/long tube header everybody uses is a torque killer. I wanted a 1-5/8”short-tube header connected to a tuned length head-pipe, and dumping into either a chamber muffler or atmosphere depending on the position of the exhaust bypass valve. Due to the location of the collector, however, it was impossible to get the head-pipe long enough, so I had to compromise. The pipe is shorter than optimal, but I tied on with a smaller mandrel bent 90 to replicate a long collector before blowing up to the full exhaust size. Hopefully this will work better than what I had.

 

 

Everything tucks under the apron, which was no easy feat. The “muffled” side of the system runs though the chambered Flomaster, then a Dyno-Max in/out turbo muffler. It has an O2 bung, and Bernoulli tubes on both exits for Moroso breather valves (they'll be connected to the breather box). I had it ceramic coated locally. Here are some shots of the exhaust going together:

 

 

The dry-sump tank was another thing I wanted done a certain way. A 911 tank fits pretty well in the passenger side wheel-well (I'm told), but it also has a filter right where I have the CDI box mounted. I decided to build a custom tank out of AL. I fabbed up what I wanted out of Styrofoam to make sure it fit, and took the prototype to the welder to have fabricated. I dry-fit the tank, located the bungs and filler tubes. I have yet to make up baffles, and take it back to the weld shop to be completed.

 

 

The engine tin became an issue. The dry-sump required that a bunch of tin be cut, and in the end, it looked “homemade”. I made up some patterns out of poster-board and cereal boxes, and cut the tins out of .060 AL sheet. I tried to make the pieces so that the “important” ones could be easily removed for access to the stuff I want to get to easily. The surround tin is at the powder-coat guy right now, and I'll get the apron tine done when the pulley set up arrives.

 

 

The pulley set-up was typical of this project. A dry-sump requires a much smaller crank pulley to clear the pump. I ordered a complete Bugpack dry-sump kit in December, but the pulley was on back-order. There was no progress by March, so I did a bit of digging. Apparently, Bugpack buys the pulleys from Scat. The one guy at scat who runs the pulley CNC had a stroke, or aneurism, or something, and hadn't been at work for a couple of months. They weren't going to make any pulleys until he got back. So, I went to plan B, and bought a $100 (plus freight) dry sump pulley from CB. CB's pulley is made by Jaycee, and is a nice piece with a steel hub bolted to a nice CNCed pulley. They did not offer the pulley cut for a sand-seal, so when it arrived I had my son-in-law cut it down at work. It was slightly too small for the crank, so back it went to the machine shop to have opened op a bit. This time it fit perfectly. It rides so close to the pump however, that a belt cannot be installed. I gave up and ordered a BMD serpentine set-up. I'm nearly $500 and 6 months into.... pulleys. It's nice though, and replicates stock fan speed.

 

This all has taken about 3 months longer than I wanted it to, but one thing led to another and, well.... you know how it goes. The packaging of all of this, while maintaining a reasonable weight was a Rubik's cube sometimes. I'm pretty happy with how it's coming together, and the end's in sight. I'll have a report on how it all works once I've got some miles logged. Eventually, I'll eliminate some of the breather tubes, and clean-up the hoses inside the engine compartment. In the mean-time, I just want to finish and drive.

"BlazeCut®(TM) woulda' saved it!!"

Excellent journal Stan of what looks to the layman like a gargantuan project.  One thing that I am not clear on is why do you especially like the dry sump over the wet sump?  My Beezer has a dry sump as do many motorcycles and I never quite understood why the manufacturers do that.  The only thing I can think of is for oil cooling.  

Stan, an enjoyable read. Trial and error costs money.  My wife has no understanding of this process.  She thinks everything should work out perfectly the first time, every time.  After 33 years of marriage you'd think she would know better. 

I'd love to see you do a water cooled install.  With your skills I bet it would be impressive.

Excellent question, Hoss-- and one my wife has asked many, many times. "alb" (it's difficult to know who that is without an actual name, but that's something I can't do anything about) is partially right about ride height.

My engine moves a lot of oil, and a lot of it ends up in the 3/4 valve-cover, especially on long sweeping left hand curves. A deeper sump would correct that, but I tried a 3.5 qt sump and it was way too low. I ran a thin-line 1.5 quart sump and ran out of oil a LOT. A dry sump completely evacuates oil from the crankcase, so there isn't a bunch of oil sloshing around, and stores it in a remote reservoir where it's always available. A big flat 4 runs a good deal of crankcase pressure for a lot of reasons, but couple the pressure with a relatively high oil level in a wet sump, and oil's gonna' leak out the back of the motor (even if it's sand-sealed). Drawing a vacuum on the crankcase actually frees up some power as well. 911s have always been dry-sumped.

It might be a fool's errand, and the layout of our engines makes it double difficult-- but I'm determined.

Stan,

I applaud you on your dry sump project. As a long time ago FV mechanic and engine development person, I can appreciate what drysump systems do for HP. For example, Oil control in the 40 hp VW FV motors (that made somewhere around 50 HP in racing form) would see HP increases by making the HP curve flat from 3000 to 6500 rpm, just by keeping the oil sump area of the case dry(er) in the Cam/Crank gear area of the VW case. Just think of the oil going around that taffy machine of timing gears.

 The motors would typically see around 30 HP at 6000 plus. Just by oil control (dry sump...sort of) we'd see that HP go to 50+ at 6000 rpm.

Great Job!

Greg

I knew a guy who raced motorcycles years ago who swore by this trick ( which seemed pretty extreme to me ) and he'd install a small venturi tube into the exhaust which was connected to the crankcase sucking air out free of charge. The theory was that oil vapour might slow down reciprocating parts and if the air was exhausted, the oil would only collect on the case sides etc., away from moving parts thus improving power. 

That works! We ended up inside our FV VW motors with screens to collect the oil vapor and turn it back into drops, scrapers to barely clear the crank and cam to remove oil as it slings off everything that moves, and the biggest thing was to isolate the cam/crank gear chamber from the oil sump portion of the case. That last change made the biggest difference.

Rich, I am moving heaven and earth to get this car running. I am DEEPLY committed to being back on the road by the summer solstice, one way or another. Money is being shoveled into the boiler of progress, even as we speak.

Now that the car has been on the road for a couple of weeks, I wanted to give an update on how it all finished up.

 

This is a picture of the oil tank before being sealed up (the final welds). The pieces running inside the tank are baffles to keep oil movement under control (slosh).

 

 

Once it was completed, I had it powder-coated with high-temp powder, as insurance in case my oil temperature got out of control (standard powder-coat is good to 240 deg).

 

I fabricated new surround tin, and rear engine tin out of .080 AL. The rear engine tin was required for the serpentine belt set-up. I had all the big powder-coating done at a place about 20 minutes from here, as it wouldn't fit in Jeanie's oven. I did the surround tin in such a manner that it can be easily removed to get access to the flange bolts for the exhaust. I had the exhaust ceramic coated (twice- the first time was not satisfactory).

 

Here are a couple of shots of the completed set-up:

 

 

 

 

 

 

 

The lines with the fiberglass covering are for crankcase ventilation. They run up to the top of the breather box, and evacuate it through means of the Moroso check-valves in the exhaust. It works really well.

 

I've got about 500 miles on the set-up, and I'm very, very pleased. Firstly, it's great to finally have control over crankcase pressure. I've got no oil spray of any kind out the sand-seal behind the pulley. The capacity of the entire oil system is about 11 quarts. An unintended (but happy) consequence of the system is the temperatures and oil pressure I'm able to run. Every day has been over 90 deg (some have been over 100), and I've yet to see an oil temperature over 190 deg, and my head temperature are running about 230 deg or so (I monitor all 4, under the spark-plugs). The pulley set-up keeps the fan speed stock, even with the reduced crank-pulley size by means of a smaller alternator pulley. The head temperatures are allowing me to run more spark advance than I've been able to get away with in past summers.

 

As for the exhaust, I'm very pleased with the smaller/shorter primaries. I've finally lost the “flat spot” at about 2000- 2500 RPM- it pulls like a train from idle. The exhaust note (through the mufflers) is tame enough to be able to easily talk to Jeanie with the windows up and the wind deflector in. Bypassed, it sounds really, really rowdy.

 

I'm by no means “done”, but I'm done for now. I should've not tried to use a VW dipstick in the tank, as it's too short and I'm puking a bit of oil out of it. I'll have a fix for that next winter. I'm still on a search for a distributor with the curve I like that doesn't have the “Mallory scatter” that has unfortunately plagued Uni-Lites since 2008 or so. I need to get my new 48 tri-jets rebuilt, and for now I'm running 40s (!) on a fire breathing 2332.

 

But for the summer I'm good. I'm able to trust the car far, far further than I ever have. It's no big Type 4, but it's really, really close in terms of the kind and amount of power I'm putting down, and the temps I'm running. The reduced temperatures alone should more than double the life of this particular long-block. Jeanie and I are using it for everything that doesn't require a minivan or work-truck.

 

It's good to be back in the car I love.

Ron- Those are the 911 engine mounts. The hanger bar (silver square tubing thing bolted to the back of the engine) attaches to them underneath. I could do away with the mounts on the bell-housing if I wanted, but I don't (I really don't want the drive-line moving around).

 

This is the hanger:

 

Stan, VERY nice work! Ditch the dizzy, get Megajolt. You'll never look back. You can do it for little more than your Hyfire 6. Sell the Hyfire and the Unilite and you'll break even or make money! Accuracy of 1/10 of a degree for a full revolution! No scatter there!

 

Mount the toothed wheel BEHIND your dry sump pulley. Move the breather to the dizzy hole, and use the breather area to make a crank sensor mount. You do need to mount the Megajolt not in the engine compartment, but the other components can go in there. 10 X 10 map for centrifugal advance and load, laptop controllable, two curves loaded and on the fly switchable. 4 onboard rpm/load triggers......

Yeah, probably.

 

The distributor thing highlights my OCD tendencies.

 

I had a 009, but I hated the advance curve. I bought an 043 (vacuum advance) re-curved by AJ Sims. I got a mechanical advance uni-lite in '08, and a vacuum advance uni-lite last year. I'm back to the mechanical advance uni-lite, and ready to try an 050 or 031. I've got a spare Mallory cap, rotor, pick-up, and a full set of springs in my spares. I've got a spare of everything for the Bosch stuff as well.

 

So.... I've got 4 distributors (two of them with customizable curves), and enough spares to open a parts house-- and none of them makes me 100% happy. I'm deep, deep into distributors, and I'll probably end up selling the whole lot off for about .25 on the dollar.

 

I want about 28 deg of total advance, a linear advance curve that starts at about 1100 rpm and isn't all in until 2800, and has a nice 5 deg or so vacuum canister. I'd like it not to scatter. You'd think I wanted shards of the true cross.

 

I keep telling myself this is fun.

Souhail:

 

If I said that, it was a mistake.

 

My tank is closer to 1.5 GALLONS, and I made it out of TIG welded aluminum sheet.

 

You want to have at least a gallon or a gallon and a half of capacity or you'll run out if the engine turns over 4 or 5000 RPM for an extended period of time. I've got a Canton Accusump as well in case I do run out.
