That would amount to little less than 18sec of boost if they use both MGUs to release the maximum of 8MJ allowed by the rules.
Now, Toyota could opt to release energy exclusively at the front (or at the back as the case may be), in effect doubling the boost duration with half the available power (assuming two MGUs each developing the same power output).
The twin ERS-K will however also increase cooling demands I suspect. I am looking forward to seeing how Toyota will package this system and the related cooling systems.

Fortunately for Toyota theyve had near 7 or 8 years to develop the supercapacitor. They were making 300hp on their full releases of around 2.2/2.3 seconds. So double that- 7MJ, they could do 300hp for a full release of 4.5 seconds going by the current formula of 7 'release zones'. 7 x 4.5 = 31.5 seconds of 300hp per lap. Thats conservative... if they go 8MJ option they can go almost 36-37 seconds per lap on the 300hp boost. You can see why theyre quietly confident.
