Is there any point in EV training a Speed Boost Blaziken in Speed?

I plan on using mine as a Physical Attacker (since it has an Adamant Nature) and it has its Hidden Ability Speed Boost. I don’t know much about competitive playing/battling, but I was wondering if there is any point in EV-Training a Speed Boost Blaziken in Speed. Most people give out max evs to Blaziken’s speed, since it’s “okay-ish”, but with Speed Boost, it would be able to outspeed faster opponents later on during the battle (unless it switches out), Although I would understand at least a little bit of EVs going into speed.

Yes.

Blaziken has a base speed of 80. That’s pretty poor even in NU, and Speed Boost Blaziken is an Uber tier Pokemon.

So lets assume all your Pokemon & your opponent’s have 31 IVs in speed.

Blaziken will be at 196 with no EVs. After 1 Speed Boost (x1.5), its speed will be 294.

However, with full speed EVs, its speed will be at 259. After 1 Speed Boost (x1.5), its speed will be at 388.5. That’s enough to outspeed:- Timid Gengar (350)- Modest M-Gengar (359)- Modest Mewtwo (359)- Timid Darkrai (383)- Timid Greninja (377)- Timid Shaymin-Sky (388; speed tie)- Jolly M-Lucario (355)

So yea. Speed EVs are definitely worthwhile on Blaziken, because it got base 70 defences which means your chances of getting another speed boost without attacking are slim.
