You're 145 and you want to hit 100psi? Are you running 19mm tires?
Seriously, though - that's a bit much.

Think 80 psi with inner tubes and gp 5000 25 mm tires is good enough then ?
or is the day I convert to tubeless and stop worrying about pinch flats ? ha-ha

You need a high pressure pump, not a high volume pump. Pumps like yours are designed to pump up wider high volume tires. Unless you have arms like the Incredible Hulk you won't get the pressure you need. High pressure pumps have skinny barrels in order to generate higher pressure. Of course they pump less air per stroke than a high volume pump unless they have a much longer barrel.
My pump of choice to attain high pressure is my trusty Zefal HPX, I can get well above 100 psi with it

I own LEZYNE HV Bicycle Hand Pump, High Volume 90 PSI. Over the last year I have changed many flats on the side of the road with it. The other day I tested it at home. I was curious how much psi I was putting into the tire. After I pumped it with LEZYNE HV Bicycle Hand Pump I put on the home floor pump with built in gauge. It was only 52/52 ish :/ Enough to ride slowly home I guess.
I am looking for pump Bruce Banner could pump up to 100 psi on the side of the road.

At best 70-80 psi will be much better. More comfortable ride and the tire will conform to things that will want to poke through it.https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

Zefal has always been a great pump - I talked to an online retailer that sells them , they said it only attaches to a brazed on peg near the bottom of the seat tube - I'm guessing Look bikes have those pegs but you also show a pic with a top tube mounted Zefal - how is this mounted , did you have to buy a peg attached to a strap for the top tube ?

Alcjphil Said ----------
There is no need for a peg at the bottom where the seat tube and down tube meet at the bottom bracket. The top tube mounted pump fits onto a pump peg on the head tube and into the angle between the top tube and the seat tube with no fitting needed. In both cases the pump is held very securely as long as you have the correct length pump for the frame in question. I have 3 different length pumps for my various bikes. In the picture of my Limongi in a previous post you can clearly see how the bottom of the pump fits into the seat tube/top tube junction. That end of the pump fits into the seat tube/downtube junction the same way
**************************************************************************************************** **************************************************************************************************** *************
The retailer Rivendell Bicycle Works does offer the pump in three sizes requiring the distance from top tube/seat tube junction to the seat tube/down tube junction - my bike , Litespeed Tuscany 2003 doesn't have a pump peg on the head tube - thanks for the explanation and additional pictures .

seriously ? ha-ha
I let the air both times.
The new pump with the gauge can hit 80 psi. My old pump is good to about 50. I tested both pumps several times. Each time I let the air all the way out.
