TIV 2056 in a bay window bus?, putting the engine in my 914 into my new bus maybe... Options

[VaccaRabite]

Hey folks.

I am thinking about taking the well tuned EFI 2056 out of my 914 and putting it into the '72 bay-window Westy bus I bought a few weeks ago.

A bigger TIV will go into the 914.

Though I have not mentioned my plan at the Samba - the few people that post in the bay window forum there seem to have a dim view of the TIV in a bus.

My engine has 1.7 heads with 2.0 valves, a compression ratio just a smidge tighter then stock (8.6:1 IIRC), Raby cam based off the Web494 grind, and is running on Microsquirt injection. This engine is putting down 127 at the wheels of my 914, according to a dyno run a few years ago - but there have been changes since in exhaust and LOTS of tuning. In my car it will run at 80+ all day long with the heads staying around 350 on the freeway pulling hills. On very hot days pulling the long PA hills it will approach 370 after the engine heat soaks, and I have to back it down to somewhat more legal speeds.

Will a bus kill this engine? IIRC the camper special had a good bit less power then my engine, but I don't recall what that combo was - or even if it was a 2056.

The bus needs to stay air cooled, so putting a suby in it is not an option at this time. Corviar is an option, but I want to retain the manual so I'd need the reverse rotation cam for the corvair. And keeping the stock 1700 is an option too.

Busses were all TIV from '72 to '83. Lots of T4 guys in the Baywindow forums over there.

I have a FAT Performance 2056 in my '73 Westfalia. It runs and drives great, runs out of 4th gear though. That will keep you from running a bus at 80mph all day. You probably shouldn't go that fast in a bus anyway...

Engine was originally built for a Sebring Kit Car on VW chassis by it's PO. I wasn't really sure how it would work out in the much heavier bus but it's been just fine going on two years now. Running dual Weber 40idf, I have an oil cooler kit sitting in the garage, just haven't gotten around to installing it yet.
