Case question for possible location for crank trigger Options

[ClayPerrine]

Zims is building a drop in EFI kit for the 914. It is running on the first motor.

Took it from about 85 wheel horsepower to 120 wheel horsepower with no internal engine mods.

And it looks like a pair of downdraft carbs. Even uses the same throttle linkage. And no chassis mods. Installation would be about 4 hours if you already have stock fuel injection. Even the basic fuel map will be ready to run.

It is all plug and play. But for best performance, you need to get it dyno tuned for your engine after installation.

@partsguy22 - Got pictures?

And there it is...
That type of performance gain on a hot 2.0 or maybe a 2.2 is what I'm after.
I'd like to double the stock power of the original 1.8 L-Jetronic which I first have to restore to its original fuel injection which came with the car.
I will run it on a dyno in stock form first to get a base line.

On the big engine I will make internal engine mods and I'm planning on using E85 which could be worth some more power. 5-10% would be what I'd expect in a non-boosted E85 set up over 93 pump.

What is a normal WHP reading for a stock 75 1.8?
I would guess 60-65.

If you want to run e85, you are going to have to retune the EFI for it.

And the stock HP of a 74 1.8L was 76.

Yep, actually I'll use a GM flex fuel sensor and have two maps which the MS3 will blend automatically. Once it's set up it's transparent. 93 octane with have a much more conservative timing map and run 30-40% less fuel.
I will be employing a Bosch knock sensor as well.

My question regarding HP was what does a stock 914 1.8 register on a chassis dyno?
If you take 76 and multiply it by .85 you get 64.6.
This is using 15% as the calculated loss through the drive line.
15% is probably less loss than actually occurs.

Has anyone baselined a stock 1.8 on a chassis dyno?

The 1.8L has not been stock in so long I forgot what stock feels like. And for a couple of young people on a tight budget, a dyno run was out of the question.

When Betty and I first met, her car was a bone stock 1.8, and it was only running on 3 cylinders. So imagine how anemic that was....

My first 914 was a rusted out 70 1.7 with a 1911?? big bore kit in the early 80s.

I was 17 years old and did NOT know what I do now...

My dad bought it as a basket case, and I assembled the jugs and heads myself.

This was LONG before I started doing my own head work and something about them was wrong.

This car came to me with the crappy progressive two-barrel Weber (which the current car has as well).

When it ran it ran OK but...

There was so much messing with the carb that I removed the engine lid for quick access.

Occasionally it would throw fireballs into the air on start-up.

At one point I set my girlfriends family tree, in their front yard, on fire at three in the morning.

This is one of those memories you retain for LIFE!

Another interesting fact with me is that I swore I'd never mess with air-cooled VWs again in my life three decades back. My wife had a Super Bettle that gave us so much trouble I hated it. I was done with crappy low powered cars that required engine removal as much as that one did. I got really fast at drivetrain removal on that car.

Well in 2023 my dad again comes up with a 914, a stupid nice time capsule 914, and here I am dicking around with air-cooled VWs again.

Back then I was apprentice/journeyman level and knew little.

Today I'm not...
