Holley Sniper Conversions.

[jroza1]

I have been searching the samba this AM because I remember an Ad here for a company that did Sniper modifications. I can't seem to find their add this morning... I blew my motor, so in the rebuild budget, I am adding a Sniper system.

Any recommendations? Is this an Ad I imagined?

For the life of me I have no idea what a sniper system is. Could it be the old DTM pictured in your link?

I bought a '72 bus last fall that has has a set of after marked dual carbs on it. I've only driven it about 5 miles so far because I hate the way it drives with the carbs and the warm up procedure because it has no chokes. I had originally intended on converting it to fuel injection from a later bay, I have an entire set-up from a '77.
I have been reading up on the Holley Sniper and am really impressed with what I've seen. I like that there is so much packed into that throttle body. The ECM, MAP sensor, injectors, intake air temp sensor, fuel pressure regulator, idle control, throttle position are all right there in one piece. All you need to do is hook up an oxygen sensor, and a couple wires. The right now is only $804 and it comes with a Bosch wide-band oxygen sensor, temp sensor, and the touch screen display that is also used to set it up with your engine.
I'm not sure how well this will work with the bus engine particularly when it's cold outside being that it is a throttle body injection but I'm willing to give it a shot. I just ordered one and will see what I can do with it.
I'll be using one of those aftermarket intake manifolds for the single carbs to mount it. I'll need to add a high pressure fuel pump and a return to my fuel tank as well.

the only thing i have to wonder is how that would work in a center mount configuration.

i swear there was a thread bumping around here on the sniper efi....performance section maybe? as i recall holley was super helpful in getting it set up.

i have to admit, i'm with andrew here. carbs are fine for what they are but FI is where it's at.

I would think a center mount throttle body setup on a type 4 would have the exact same problems as a center-mounted carb: the fuel would condense in the intake runners without heat. Port injection would be MUCH better...

I find this really intriguing, if it's tuneable there may be a way to get around some of the single mount Weber issues, of course a heated center section (preferably by exhaust gases) would be the way to go, but it'll be interesting to see how much you can overcome just using computer code.

I ordered this unit back in early July, after a few weeks I contacted them and they said it was on back order until early September. I just contacted them again today and was told "We apologize for the shipping delay. As of today, the next estimated shipping date is 10/15/21".
Still looking forward to trying it out on my '72.

kudos for the update, The trick would be two, one on each side instead of the center.

The puddling issue may go away anyway. I may have already said this but FI doesn't have the same issues as a carb with a venturi that creates the colder temp and venturi icing. The fuel is pushed in under pressure instead of being drawn in by a vacuum difference.
