Building a race bike

You see the top fuel drag blokes wearing pretty high tech respirators when they start their Nitromethane rails in the pits.

In the season when my business partner and I ran a GSXR1100 on the Meth/Tol mix i remember him checking the rear tyre pressure in the assembly area at Teretonga - and having to roll away from the bike before he passed out.
Vicious stuff indeed.
But at that meeting - NZ National round - Holden on that bike was first ever under 1 minute for the lap. A time only the top 3 or 4 current moderns can match.

This is because one of the resultant exhaust gasses from Nitromethane combustion is Nitric Acid and when inhaled it causes the muscles in your lungs to stop working and you can't breathe. Good night. Lovely stuff!

Anyone who has not witnessed a top fueller first hand really needs to make this a bucket list feature.
Stand near the start line and hold onto something when they hit the loud pedal. I kid you not, you will not be ready for it and your legs will try to give way when they put a combined 20.000hp through the ground and out of the exhaust pipes into the air. Shock waves from exhaust and through the tyres is absolutely incredible!!!!!

could not agree more, is the most awesome display of horsepower a human can witness anywhere
your eyes water from the fumes, your throat constricts from the fumes, your eardrums are aching and your lungs and chest are vibrating from the sheer power that these Top Fuel cars put out, is a once in a lifetime experience

I have seen them at least 427 times now, just love seeing Top Fuel cars run
 
I guess the only rival to that would be a Rocket Laught, one day I hope to see one of Elon's multi-engined big rockets go, way bigger than a Saturn 5. Interesting times ahead I hope.

Saw/heard/felt one lifting off from Kennedy Space Centre/Cape Canaveral, back in the '90s. I'd just landed at Space Coast Regional Airport, on the other side of Indian River. I was buttoning the aeroplane up when all hell broke loose. A very impressive event.

....... and you cannot get the sense of the acceleration from a video. When you see it live the rate of acceleration is almost unbelievable .......... imagine 1/4 mile in 5 seconds. Amazing!

Rocket launches are absolutely awesome spectacles, I have been lucky enough to see a couple of them and saw a 'Space shuttle' glide into a landing at Edwards AFB, memorable. There is a Falcon 9 SpaceX launch scheduled for this Friday weather permitting from Vandenberg SFB north of Santa Barbara, if you live within 30 miles of the base if it is clear you will see it and hear it. Here is a link to space launches in Califonia for 2022, click on the links for dates.
 
Inlet rocker mocked up in steel to test before making from billet 7075-T651
Making the exhaust rocker next.

These are made to check alignment of the valve as it opens and closes etc, the valves will have an awful lot of lift so the sweep of the follower is extremely important.
I then have to design the cam shape in order to translate that to valve lift, with the rollers it is not simple as the lift ratio changes quite a lot during the lift cycle, starts high (fast) and finishes lower (slower) for the inlet, the reverse for the exhaust, which is actually exactly what you need them to do but bloody hard to calculate, even with cad it takes some doing.
