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.

Street Eliminator heads 44x37.5 valves

Exhaust port.

inlet ports.



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.

Nice work Dave, will you build an engine for my oval?

Nice work Dave, will you build an engine for my oval?

If you have about 8 to 10K then i carnt see it being a problem .... Thats if you purchase all the stuff new of the shelf.

:thumb Didnt make it to Dyno Day but Dave's beetle was my favourite at Valla, was actually just saying that I admire Daves work...nice work all the same

I love the single cab as well

Yes i realise that ... Beck does nice work

But thats the cost for a decent engine nowdays using new parts..

Makes you think dosent it... I aint got the funds to do it...

D'oh - just read Dave's post

Um.... thanks Craig 🙁

how do you find teh magneto ? I have one lying around I was going to try on my buggy .

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.

CYA, CT

What was your hp at the Dyno day?

Awesome! The thing looks simply stunning. Pure eye candy for any aircooled lover 😎
You must be very proud, Dave. :thumb

He should be proud, I have never seen one of Daves motor's not perform :thumb

It was a fun project, and when it performs better than you think, its an added bonus.

p.s. that whole beetres is awesome gotta love it!

Gees,

I wonder what that puppy has at the flywheel?

When's the first teardown and inspection?

RobK

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.

F@#$ing christ mate thats some serious power!!!! i will have to go for a drive with u next time ur up my way!!!
cheers
rhys

Man, that is one truly inspirational engine there good work! :thumb :thumb

:party

GB315 is the same as a FK89 ??

Excellent Dave, just wondering what fuel
you run with that 10.8 : 1 compression..?
I would run AvGas, or can you run Prem UL.?

Nice:thumb
Just wondering at what revs does this beast make peak torque?


Andrew Grace

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 😀😀
Or should Dave be using 1.4's 😀😀
