VW Type 1 into 914, What are your thoughts? Options

[james2]

I have a 2332cc Type 1 engine. It dyno'd at 210 hp and 200 ft-lbs of torque on jake Raby's dyno.

Would I be viewed as a total hack if i put this in a 914?

Any form of forced induction breeds efficiency.. Without boost its hard to get more than 100% VE from an engine thats aircooled with less than 11:1 CR, however I have been able to squeeze 122% from the 1500cc Land Speed engine that currently holds the ECTA record.

An engine that performs best without boost, typically won't have the optimum CR and combo for boost so doing a back to back comparison is difficult. The best back to back I have done is a stock 2.0 that made 88 HP N/A made 160 with less than 10 PSI boost with no other changes and non intercooled.

All other engines I have boosted tend to make double their N/A output at 1 Bar boost. I have two Turbos on deck now, one is a twin plug 2332 TI with a dual ceramic ball bearing Turbo and the other is a single plug 2.1 L TIV using an 82 stroke and 91mm bore with a T2/T3 hybrid custom Turbo that is also dual ceramic ball bearing.. I expect both these low CR, mild cammed engines to make less than 140 HP N/A and both over 300 at 1 Bar boost. Both are made for low revving applications that need smooth power and little lag.

The last Turbo I built was 80X100 and made 283 HP @ 10 PSI boost with 340 lb/ft of torque..

Out of curiosity; how do you keep your turbos cool? This Garret I have setting on the shop floor next to my project has these two lines going to it, one on top and one on bottom... and originally it had this really big thirst for green kool-aid of the ethylene glycol variety.

So how do you cool a turbo that comes from aircooled heaven? (the ceramic bearings must help a bit!)
