Firepunk on the dyno at UCC 2017

[@michaelking1869]

The ether is due to the low compression. Ether will light off at a very low temp which with the low compression helps to get the cylinder temp up enough to start hitting on all cylinders. It's not uncommon for a race diesel to be in the 12.5:1 compression range. They don't light off quickly with compression that low.

[@mrcobus86]

Michael King most heavy duty commercial diesel engines are in the 13:1 to 16:1 Caterpillar/Cummins. High performance diesels in tractorpull or racing are like 8-10: 1 but 4 turbos and 300psi boost

[@abhirmalhotra5103]

What you're saying isn't correct.

[@ruxoneto6560]

I would guess the compression is lower than 12.5 , probably closer to 9.5- 10 .0.

[@farmyardfab]

This was also with a SIGMA 17mm pump. It's a tractor pulling pump, they have poor control of the injection cycle at low RPM. Destroked common rain engines idle and build boost much better and more controlled.

[@foxxx5.941]

That's the awesomest thing I ever seen

[@rvjscarestheginger4857]

Thanks not only for cool vid but a good description!

[@TT2.7F150]

After it clears up from the ether it almost sounds like a Detroit 453t 😂😂

[@crazyhass84]

quick get a bigger can of ether!

[@doserdiesel]

I wish I had 10k for a basic Firepunk trans If I win the lotto I am in!!

[@markrich3271]

Why does he need a pint of ether prior to the run?

[@justinmartin8887]

Low compression, advanced fuel injection timing

[@TT2.7F150]

How many RPMs is she turning?! 😳 sounds close to like 6 or 7k

[@El_Heep]

Probably pretty close to what you said

[@taylorraber7320]

If I remember correctly, their datalog of the truck showed 1500 more rpms than the dyno read. They spun real hard

[@gavinmcvey7682]

Wow sounds good

[@next2talljones]

The horsepower and torque numbers are reversed.

[@RyanLeeProductions]

next2talljones yeah that was a mistake on my part

[@nikherren3254]

You would thank it had more tq

[@bluelightning414]

Needs chrome stacks in the back.

[@Wyatt.6oh]

1:32 my pc 32 chuncks on minecraft

[@psychotikpaisano]

who made 1st place on this dyno?

[@RyanLeeProductions]

psychotikpaisano Shawn Baca in the Master Shredder truck got 1st place

[@psychotikpaisano]

ahh I see. big surprise right? I was rooting for the Wagler DMAX but it seems like they haven't gotten the tuning part down yet

[@antilagboostaddiction8322]

psychotikpaisano me to truck is insane.

[@4wdaddict41]

What kind of transmission do these 3000 plus hp trucks run

[@paulstewart3153]

That truck has a 48RE in it

[@vinzchannel01]

That's a rotary

[@TT2.7F150]

5000-6000 rpm diesel

[@MrDJ217]

wow

[@majhahatasurkreetaliwaweeh3483]

Run liquid hydrogen no smoke soot clean

[@kyleedwards5436]

What's with the either? Is that how hard it is to spool up? I'd say that's about worthless in the real world.

[@willonthegrill9474]

kyle edwards well it is a completely dedicated race truck... it’s made from the ground up to make it down the track not down the street

[@Sir.VicsMasher]

[The real world...] This is a race truck at a competition going for the win, has nothing to do with real world driving just like F1, NASCAR, Monster Trucks, Formula Off Road, etc. The ether is used to get the race engine up to temperature especially during a timed event.

[@taylorraber7320]

In this scenario the ether was used specifically to spool the truck. The sigma pump on the truck delivers so much fuel, you cant just rev through it without killing the chargers and stalling the truck

[@klaasover]

Useless

[@ldnwholesale8552]

The engine is goof for WHAT, takes minutes to spool up with enough pollution for a small city!
