'75 high compression V4 crossflow intake stuffers and pump gas?

[powerabout]

Just a stock 135 thats all
Whats your cranking compression?

[pcrussell50]

Filling had been SAE standardized for over two years. No problem

Hydrogen's a great fuel, no question about it. If you can tolerate the huge tank, or tolerate a normal sized tank and short range, you'd be in business...

Notwithstanding the powerful politics behind the current battery fad, hydrogen holds way more of a workable solution than batteries... again... if you can keep politics out of it.

Crossflow yes but different animal. 3.415 bore Chrysler 165-170 on pump. I was asking about clearance wondering if the 9 pages had tighten and worked the chambers? Getting to .040 and working the chamber to keep a pump gas psi .

sure but the power absorbed to create and compress it is huge, so its going to be a while before the grid is solar powered then we wont care.
If each gas station has to have high pressure tanks or be multiple times bigger than they are now its lots of space getting used up.
Gas station that is just a bowser but plugged into the mains for power is way smaller, cheaper, simpler, safer.

I'm not saying hydrogen wont work but its a few years out thats for sure.
Lets wait to see a recreational boat with a fuel cell and batteries and elec motor that can plane....

Plenty of work going on in the offshore industry. There are several rig supply boats 80-90m that are lpg and with some fuel cells and some with 3.5mw batteries in them as well for back up.
Autonomous ships for local waters are being worked on lots, deciding what power source is best is where they are doing the work.

We have stations here

We have stations here

how many cars can they fill an hour and all day?
I read a road test on a hydrogen car in CA and they said its very limited as the station takes hours to recharge once its done a few cars.
Not sure of the process there?

Some energy densities in kWh per liter:
9.5 – 12 = the good old Coal
9.9 = Diesel
6.2 = LNG at -162°C
2.4 = Liquefied Hydrogen at -253°C
1.6 = Pressurized Hydrogen at 700 bar

we're gunna need a bigger boat

Back on track.....pcrussell50 does the cowl on the 140 on your Viper have any vents added to it? If so where are they located? I'm in the process of modding my cowl and just interested in others. Thanks

Hi Gary, no, my cowl is not modified. I have called my motor a "140", but truthfully I just said that for simplicity. It is actually a "Frankenstein"... meaning, it has been built out of parts from many different years of the v4 crossflow, as well as some aftermarket parts, like Wiseco pistons and I don't know what else. I'm only assuming that after all that effort to hand pick parts, that it's about a 140. I wish I knew more about it, but it was already on the Viper when I bought it and the teenager I bought it off was not the one who built the motor. He didn't know anything about it. Runs low-mid 60's in the Viper with just me in it. Viper has sharpened strakes, raised transom, and flat pad. Don't know how much the flat pad hurts or helps. I've heard both arguments. I just know that it handles fine at 60. Don't know how that would change at 70 or more with a bigger motor.

Yeah gary back on track or start a hydrogen thread.

Yeah gary back on track or start a hydrogen thread.

The shop that built the Wiseco piston v4 crossflow hanging on the Viper in my picture is from Minneapolis//St. Paul area, I'm told. Wish I knew more.

[racervboat]

Don't know why you say custom wiseco's or have they been scalloped?

[pcrussell50]

The motor was custom built, with Wiseco pistons. That little comma means a lot...

custom built, Wiseco piston, bubble-backed "frankenstein" crossflow

-Peter

[powerabout]

if you pop a bypass cover you can see how both a scallop or not and the inlet ports
Does it have stock 135 main jets?

That would make a good thread Gary i would be interested in how many mods can be done
