Kinsler Fuel Injection
 

Anyone use Kinsler for a conversion or upgrade?

Just wondering what your experience was good or bad. Did you deal with them directly or through a dealer or builder?

Also which system did you use?

Do they make a marine system?

Are you talking mechinical or electronic?

Their mechanical (constant flow) systems are pretty much only suited for racing. Their electronic systems are just other manufacturers systems. In that case you're just paying for their expertise in setting it up, and like the previous poster said, they're not marine specific.

They've been around forever. Their rep has always been that they do quality work, but you pay for it. Often quite a bit more than you'd pay elsewhere for quality work.

I have found a decent source of fuel injection information is Tim at Marren Fuel Injection.

Thanks;

Well, they are calling the system we are talking about "marine" It is EFI with 8 throttles. Pick up for timing is in a Hall distributor set up.

I would guess Marine means sealed ignition and timing boxes and flame arrestors..

And yes they are expensive but it is supposed to be ready to go when you get it (Figuratively, I am sure there is still set up/programing issues)

This is the unit. I believe Kinsler is the manufacturer of the manifold and throttles. About $10K per engine.

Their port throttled manifolds are truely a work of art. You'll want to sit one on your coffee table for a while before you install it on the motor.

However, unless you're racing, port throttling isn't necessary or desirable. You will not gain any power from that feature and it will necessitate occasional cylinder-to-cylinder throttle adjustment (a pain in the butt). The only thing you will gain is throttle response (IF it is tuned perfectly). If it is not tuned perfectly you will gain nothing. Port throttling is not very forgiving.

Also, this manifold is tuned for pretty high RPM. I would guess well over 6000rpm depending on engine size. You will lose considerable torque over an ASM manifold. And what will you do about a flame arrestor? These bell mouths are meant to run in undisturbed open air. You'll have to put a pretty big box on top of it.

Not trying to rain on your parade. Kinsler makes good stuff, but has always been for race vehicles only. You didn't mention what your application is, but unless you're building a strictly racing application, there are better options.

Great stuff. I have more questions for later.

YUP!
