2176cc engine spec with pics


For those interested, These are the engine specs of my 2176 engine that ran at the dyno day.

Engine case is an Brazilian AS21, with std 8mm head studs.
Crank is an old Okrassa, with 78.4 stroke.
Rods are VW reworked by Pauter.
Cam is a berg GB316, 329 duration and 0.416' lift at the cam.
1.25 to 1 VW ratio rockers, on solid shafts.
Berg Chrome moly push rods.
Magnum straight cut gears.
Piston and barrell kit is 94mm 'B' kit.

Heads are old Street Eliminators that needed a lot of work, fly cut for 37cc chambers, 44x37.5 Manley stainless steel valves, Berg dual valve springs, compression is 10.8 to 1. The heads were done by Martin Francis

Carbs are 48 IDA's with 42mm chokes on tall manifolds, and a Berg linkage.

Fuel pump is from a 70's EFI Kombi with a Malpassi fuel pressure regulator.

Ignition is a Scintilla magneto, with a modified advance curve, and heavy leads.

Exhaust is 1 5/8 merged with a stinger or for the street a crappy nameless brand muffler to keep it quiet.

This is the engine case with crank and rods assembled.
http://a3.cpimg.com/image/27/64/27001383-8c92-028001AB-.jpg
Street Eliminator heads 44x37.5 valves
http://a1.cpimg.com/image/25/64/27001381-8a06-028001AB-.jpg
Exhaust port.
http://a2.cpimg.com/image/26/64/27001382-8994-028001AB-.jpg
inlet ports.

http://a7.cpimg.com/image/21/64/27001377-516a-028001AB-.jpg

This engine was built on the cheap, most parts were used, the cam, barrells, piston rings and valves were the only new parts used.
I got the crank for nuthin', It needed a grind. I swapped a set of used 044's for the street eliminators, Case came from Phil 74 kombi,s old beetle that was crashed. Most other parts were found at swapmeets. I put it together myself.

Brilliant Dave.


Mucho respect!

Dave you've obviously done a great job putting the engine together and getting the combo right. Well done.

Your car and your engine bay is also a credit to you.

You're a legend on the dyno and down the quarter.

It blows my mind that you're only a few horsepower behind Leigh's high tech turbo gadget.

Rob, I had it apart last week to change the big end bearings after oil lighting it at Eastern Creek drags. Just a precaution, they did show signs of running without oil!:o, everything else was fine.

Rhys, it made 143.6 hp @5900rpm at the rear wheels.

Dave, is there any reason you did not have the case face's machined flat ??

This would make sure all barrells are parallel to the crank and that the bases are the equal distance from the case centreline.

Blue74 and 70 Autostik, have you worked out the Valve lift as a % of valve size :D:D
Or should Dave be using 1.4's :D:D

Craig, if you have a close look at the barrell seat you will see that it has been machined, all the deck heights are the same.
