Hi

  Tebs here and I just wanted to share my Super Secret Engine build that took place here in beautiful Central California..  

Principle people involved:  Pat Downs, Scott Sebastian, Anand Rajani, Carey Hines, Robert McEwen, Troy Sloan, John Borgess, and myself (Tebs) ..  All this help we could damn near start a racing team.. HMMMM.

I wanted share this with all of you to just to say that if you have little to some  knowledge of how  these cars work you can achieve your goal of a well balanced,  strong performing car that meets your driving needs.  I cannot stress enough,  we all have different ideas of what we want out of our cars and I wanted to pass this on because the people mentioned are all very Knowledgeable and had no problem helping me when I had questions, and I hope this helps someone like myself who's not a master mechanic but understands the mechanics, and is looking to get the best from their car..

Although my original engine ran very strong, it had a lot of issues along the way, most of them remedied by Pat.

OLD ENGINE:  (NAME NOT TO BE MENTIONED)

74mm stroke x 90.5mm bore  "1904cc" CB 74mm chromoly crank, 5.400 length connecting rods, Engle 100 camshaft, 043 VW casting heads with 35.5mm intake valves, 32mm exhaust valves, stock springs and retainers, 30mm full flow oil pump, lightweight chromoly flywheel, stock Sachs pressure plate, dual 44 IDF weber carbs with 32mm venturies, Magnaspark Digital ignition, 9-1 compression, Empi aluminum engine case, cut for 90.5 cylinders, CB aluminum push rods, 1.1-1 rocker arms on solid shafts with swivel feet adjusters.. Producing 78 HP and 105 ft lbs torque

After Several meetings with Pat and Anand, I had Pat build the following:

 NEW ENGINE: Built by PAT DOWNS (BIG POWER) 

82mm stroke x 90.5mm bore   "2110cc", 82mm chromoly nitrided crank, 5.500 chromoly H-beam connecting rods, CB #2242 camshaft 256 duration @.050 lift .380 lobe lift, CB 1.25 ratio rocker arms on solid shafts with swivel feet adjusters, CB aluminum push rods, 043 casting heads, CNC ported with CNC re shaped combustion chambers, 40mm intake valves, 35.5mm exhaust valves, CB #vw650 valve spring/outer spring only, chromoly retainers, 62cc combustion chambers, 30mm full flow oil pump with keyed gears, billet cover, 82x90.5 magnesium engine case, full flowed clearenced for bore and stroke, Std. weight flywheel-17lbs, 8 doweled, Kennedy stage-1 pressure plate, chromoly gland nut, CB lightweight racing lifters, Stainless steel racing push rod tubes, Mahle 82x90.5 piston/cylinder kit with tru-arc wrist pin locks, Magnaspark digital ignition, custom made Berg breather box, Dual 44 IDF weber carbs with 32mm venturies, match ported intake manifolds .60 idle jets, 200 air correction jets, 135 main jets, CB billet crank pulley, All rotating components balanced, 8.8-1 compression.. Producing 160+ hp with and average of 165 ft lbs torque.. 

Pat Did say that with my fan and standard size pulley to deduct 13.5 hp.. LOL LOL he hates my exhaust and he deducts (depending on his mood) 10-20hp.. but its more like 5hp.. my exhaust kicks A$$..  lol sounds good too!!  Just ask Anand!!

Pat is a master at engine building,  all you have to do is explain to him what you want out of the engine and WHAM!  He puts all the pieces together and you get what you ask for .. AND THEN SOME!!

Pat did send me a dyno test of the exact same engine build and I will attach it.

TRANSMISSION:  Built by Scott Sebastian (Metal Craft High Performance Transaxles)

3:88 R&P  1.  3.81  2.  2.06  3.  1.22 4.  .082 (  pseudo 5 speed..)

After break in,  its clear the car has a lot of power and the gearing is producing  the best results ever..  example:  in 4th it cruises at a cool 3200 rpm 80mph and quickly goes to 90 MPH at 3600 rpm and way more peddle to go.. Pat clearly designed the engine to perform as the rpm increases,  it seem to never end and the cars torque is incredible...   Rev-limiter set to 6800rpm..

You might laugh but I put a lot of thought into this whole build.  I have been a big fan of Indy Car and loved the dynamic that goes into those cars  so I applied the same basic principles when it came time to put it all together..  Hell I even factored in tire size  because in the gearing  SIZE MATTERS..

TIRES and RIMS:  Vredestein Sprint Classics 165/15 86H  On Wide 5, 15 x 4.5 rims ..(Thanks Anand).. 

SO there ya have it kids!!  All in one big Stan G type rant... 

Like I have been saying in some of my posts we all have different ideas of what our cars should be.. Me,  I want mine to be as close to an original speedster looks wise as possible and have strong reliable power plant to get me to the coast 1/2 hour faster..  And it does just that... !!     

I may have an extra car for sale after the SLO meet end of June .. That's if Ted  (TRP) is willing to put up his pink!!     We shall see,  Stay tuned Kids!!

Best regards,

tebs....

Excellent Choice Tebs!  I have nearly the same engine from. From CB too. Mine dyno'ed at Chico's Performance here in Arcadia Ca at 132 hp @ 5900  rpm and 137 lb/ft@4000 rpm.  For better driveability and fuel consumption I have since re-jetted to slightly smaller Idle's and mains. I love to drive this car and so will you. It's still HARD for me to keep my foot out of it. The traction bar got rid of the wheel hop so now it's even more tempting !.........Frafagnugen !.............Bruce

Great example of a well thought out Speedster engine, Tebs. The torque curve is pretty flat. Anything over 2 liters makes these cars just so much more fun!  Couple of questions- is there a reason Pat used 90.5's and not thickwall 92's or 94's? And can you tell us about the exhaust?

And don't forget to drive Terry's car when you get a chance; I'm interested in what you think... Al

 

 

Teby, don't drive Terry's car.

Many have thought they were strong enough - that they could drive the five-speed and just walk away.

But the five-speed - she is a devil woman, Tebs. Once you hear her voice and have her in your hands, you will never forget her.

She will haunt you in the mountains, she will haunt you in the canyons, she will haunt you even in the dusty streets of Fresno. She will make you see gaps in your life that you never knew were there.

If you're happy with four speeds, if your life seems full and complete, let it be. You are a lucky man.

Party at the surf shack. Savor the shrimp tacos. Nurse a Guinness as you watch the sun set over the blue Pacific. It's all any reasonable man should ever need.

The five-speed has been the ruination of far too many sad souls, Tebs.

But.....Only if you can't get a pint of Murphy's......  

I have to be a true "Corkman", after all.  We're not Rebels for nuthin.....

But, if your wife is joining you at the Pub, well, then........

Smithwick's is the one for YOU!

God......How I do miss Ireland.

 

I went to the Peace Officer's Memorial last Sunday in Sacramento which is held at the State Capital. Sunday night is the candlelight vigil and the reading of the names of the officers from California that were killed in the line of duty. Luckily and thankfully there were only four officers in California killed in the line of duty during 2015.

Anyway, the Los Angeles Police Emerald Society Pipe and Drum band plays at the vigil on Sunday and the Enrollment Ceremony on Monday. After the candlelight vigil on Sunday a hundred or so peace officers head to an Irish Pub in downtown Sacramento called De Veers. We celebrate and toast our fallen comrades and pray we don't loose too many during the current year.

The LA Emerald Society folks always come by the pub and play a dozen or so songs on the pipes and drums and I always buy them their first round. You can bet it's always a Guinness or a Smithwick's.

BTW, if you've never been in an Irish Pub packed full of cops and 8 guys/gals playing the pipes and drums you are really missing out. It's loud but it's fun.

"It's loud but it's fun."

The definition of being "Irish".

Haven't ever been in a pub full of Irish cops, but have been to McGreevey's in Boston, the nations oldest "Sports Bar", when Dropkick Murphys is playing, and hanging out with a bunch of Irish Hurley players - pretty much the same thing, only LOUDER!

If I could get out to Sacramento, would love to visit DeVeers.  Yah can't go wrong with a good Irish Pub!

And you guys have GOT to try Murphy's Irish Stout.  No decent Corkman would ever drink that "English" Guinness stuff, unless he couldn't get Murphy's (or Smithwicks).

BTW:  In "An Irish Country Doctor", a series by Patrick Taylor, the good doctor, Fingal O'Reilly, has a dog named Arthur Guinness, who only drinks Smithwicks at the local pub (the Muddy Duck) in the village of Ballybucklebo, a mythical village in Northern Ireland.  The series is a great read......

"BTW, if you've never been in an Irish Pub packed full of cops and 8 guys/gals playing the pipes and drums you are really missing out. It's loud but it's fun."

Well, the pub wasn't full of cops, but was on the West coast of Ireland in Doolin, the traditional music capital of Ireland.  What a great time.  We were there years ago, and we'll be back again.

Me?  Irish since 1640 when Cromwell invaded from England. My ancestors settled there, and developed the area of Carley's Bridge and Carley's Pottery. 

Here's a green smiley to you all 

Alb, I like smaller bores for street cars because I feel the rings seal up better and last longer. The thick wall 92's made by AA fixed the thin cylinder wall issue associated with 92's but honestly, I hate the quality of the AA piston. Sure they are great for a cheaper engine build for their cost savings but for an engine that is going to see many hours of use, I do not like or recommend them.  Teby was plagued with blow by on his last engine resulting in leaks everywhere. His new engine is solid, no leaks, no excessive crank case pressure and it will stay this way for a long time the way he does the maintenance on his car.

Also, knowing a person is 3/4's of the battle when building them an engine. Teby wanted a trouble free, leak free, engine that makes allot of torque yet still revs well past 6K rpm. Teby drives his car, it's no garage queen like many speedsters. Big bore engines are great, they make tons of power, but they do come with their draw backs for a person who wants to use their Speedster every weekend in the Central Valley of California where temps can exceed 110 degrees Fahrenheit in the Summer.  

A LONG TIME LISTENER AND FIRST TIME CALLER FROM CANADA,  AL B. ASKS:  "And can you tell us about the exhaust?" 

Dear AL B.:    The exhaust was made from an old Vw canister type exhaust (I think) to try and replicate the original.. They did a great job with it it sounds amazing and looks great.. But Pat states its robbing my engine of HP..  A small sacrifice, I say,  to keep my authentic look, especially when I gained twice as much HP than I had.. IMG_3963IMG_3974

 

 

 

MITCH:       Regarding your 5 speed comment:

OK I will be driving Penny (IF ALLOWED) BUT!!............

My good friend and Guinness drinking brother from another mother, called in and made this comment referring to my cars:

" 6 in one (911 Carrera S) and 4 in the other (miss Jill 356), sounds like an average of 5 to me." 

Hes right!!  

I will be at the Surf Shack tomorrow night..  The sunset is supposed to be awesome over the pacific, and the best view from Fresno ever...    

 

TEBS

 

PS.....  Smithwick's  is awesome beer Gordon!!   Drank a few when I was in Dublin is a very smooth ale...

Teby- Just call me Al (come on, you know the tune!). Did you guys add bigger tubing to go from the heads to the muffler itself? I get why you did it; I guess the problem is that I don't get why those of you that go to great lengths to make your replicas look like the original do it. I don't see the point, but that's just me, as that's the beauty of owning these things; we're all free to outfit our cars any way we want.

Your 911 may have 6, but the Speedster only has 4, and no amount of averaging by your Guinness drinking brother from another mother will give it 1 more! Drive Penny, and get back to me...

Well, maybe it's like this;  I grew up in a 1730's, field-stone farmhouse that my parents built.  Everything was "period correct"...  Fieldstone walls, exposed and pegged posts and beams, cook-in Rumford fireplace with a pot crane, bean oven on one side and a firewood cove on the other, 18" wide oak floors everywhere, Hitchcock furniture, Dutch door in the kitchen, original carriage lights at the front door with original bulls-eye glass side lights, slate roof, all that stuff.  Only, it wasn't an original, 1730's farmhouse - it was built to look that way.  My Mom went to great lengths to make it look "original", just like the houses on the green at Old Sturbridge Village in Massachusetts, a recreation of a New England village of the 1820's.  That was her "thing" and she loved it.

After we all got married, us three kids really had had enough of living in the 1730's and went to a significantly more modern look in our homes, but we all found ways to incorporate some of the "old ways" in as well.  Like the Rumford fireplace I put in my house.

Everyone has their "thing".  Some of us do it with homes, some of us with cars.  And some of us do both.....

I understand all that, Gordon; what I don't get is when you're free of the constraints that the P crowd live with when you own a replica and can do it up any way you want, going to the point where you're copying the way it could have looked (if it had only been a "real" Porsche) from the factory just doesn't do it for me. I see an opportunity to build the ultimate sunny day car, but I understand that isn't for everybody either. Do you remember the guy (it was a while ago) that insisted on using drum brakes all around because that's the way they came? Not only is that dangerous (in a panic stop from 80 mph I'm guessing a drum brake Speedster would overheat and have nothing at 35 or 30 mph), that's as anal as they come!

As has been said, there's room for us all under the tent, and I can appreciate what other guys have done, even when it's not the direction I would go myself. 

Where I think I would draw the line personally if I was building a replica that was as close to original as possible is safety features. Front discs being the most obvious exception I would make. You can't see em' unless you are under the car, and if they stop it, you won't be under the car.

Airbags ain't gonna happen, and frankly, the fiberglass body is not much help. I don't think anybody is building frames for our cars that incorporate crumple zones, so we start off at a disadvantage all the way around. Our steering columns don't collapse, and if the 4 black rubber parts end up pointed towards the sky, well, not good.

Seatbelts, fire suppression.....????

I think Merklin called these things four wheeled motorcycles once, and I think he nailed it.

In defense of fiberglass, our rides hold up well in a crash.  I repaired a VS super wide that tangled with a large SUV that  speedster was rebuilt to like new. MUSBJIM"s VS got hammered, was insurance totaled and they paid Jim. A close look at the accident photos show that it held up darn well and both Jim and Ginny walked away with just bruises.  The bonded 2 x 4 steel box frame is extremely well engineered and the wrecks I have seen substantiate their durability. If only something could be done to strengthen the doors....

I ran one off into a country road into the edge of a corn field but that was a total lack of respect for the Type IV Raby power :~)

I have considered building Teby an exhaust system that exits the rear of the car like he has now but flows better and uses larger 1-1/2 primaries. Problem is time, I have a busy schedule with work and my family. Teby's car would perform much better, although he does not believe me when I say this lol. It is hard for me to see a loss in power over looks. I'm a horsepower hungry person, I want it all and then some. Some day I will sway Teby to move away from his horsepower robing tin can muffler, it's just gonna take time=)

LONG TIME LISTENER AND SECOND TIME CALLER, AL, ASKS: "Did you guys add bigger tubing to go from the heads to the muffler itself?" ( REGARDING MY EXHAUST)..

NO...  looks like stock tubing to me..

hmmmmm maybe that's what it needs!!

That will be excellent.

Will there be shrimp tacos? There's always shrimp tacos in my fantasies. 

These are tacos but they don't look like shrimp:
