No Type 1, just showing how with FI you get more power with the same engine.

No Type1's make alot more power than type4 due to exhaust ports.
This is a daily driver 66 bug.

If T1s make more power, why do so many people go with a T4 conversion? Am I missing something?

It doesnt look like a turbo powerband to me. Turbos tend to be less linear. But what do I know, im just a kid.

Yeah, I agree with scott. Its probably a drag motor or something running on race gas. Who else would dyno a bug motor? (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/hide.gif)

edit: whoops, didnt see it was a daily driver. power to the nazi road oilers!

I'm willing to bet the difference wouldn't be as substantial on a stock or near stock motor......still a nice improvement.....figure $50 per horsepower if the FI cost $1500.....

no one is saying FI cannot give more HP, but you cannot claim 20-30% across the board on all applications.....

Jakes new heads I believe are going to be using the Type I exhaust style, those should be some awesome parts to get a hold of once available....

Golly, Honda, Ferrari, NASCAR, et al, have to spin their N/A motors to 9k to get more than 100 hp per liter.....what a bunch of clowns. (IMG:http://www.914world.com/bbs2/html/emoticons/rolleyes.gif)

comes from the factory supercharged.......might be a good sized blower unit for a 914 engine (IMG:http://www.914world.com/bbs2/html/emoticons/smash.gif)

Don't forget about the Toyota 4A-GZE motor. 1600cc motor that spins to the moon. That has a blower, and has a clutch on it so you can turn it on and off. Sounds like a good use for that FIdle circuit on Megasquirt. (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)

Later,
Tom

I replaced this winter the FI system (stock D-jet)-injectors, TPS, CHT, MPS, throttle body, boots, vacuum hoses, trigger points, distributor breaker plate etc..

This Spring I have been replacing/updating the brakes and suspension on my '76 over the last 2 months; been sitting outside (but covered) all that time (including 2 blizzards). Saturday, for the first time in months, I decided to see if it would start so I could test drive it and seat the brake pads.

Turned the key, and it started instantly - no hesitation, no cranking, after 2 months of sitting it started like it had just been turned off.......

No carbs for me, thanks!
