Max power from Vortech H67B kit?

[Super05]

Subaru brother here.



Does anyone know how much power you can do (on E85 or water/meth or high octane) with the Vortech H67B kit? What kind of power and boost levels do you get if you rev the supercharger out all the way to the max impeller speed of 52,000? I am interested to know how much power it can make without overspinning the SC (52,000 is max RPM per Vortech?) and curious what boost level this is.



I run 12psi Raptor EJ253.. very curious how the Vortech H67B compares. The FA20 with Vortech H67B is the closest comparison I can get since nobody has ever put an H67B on an EJ253. With the current Raptor setup, I'm looking at into the 300whp range with water/meth at 12 psi, that was starting with a 120whp motor but I am at the Raptor's RPM limit at 6400rpm. Just exploring options.

Anyone hitting 350whp on E85 or water/meth? Just trying to get an idea what this SC can deliver.

This may be a good answer to my Question

I made 358WHP 9psi e85. I am not 100% sure how accurate that number is. Stock cars normally make 170's on it.

+180++whp ?! That is great.

I forgot to ask... what pulley do you run? (How fast are you spinning the H67B).

According to the compressor map the H67B can flow about 450 crank hp @ 16 psi although they only advertise max boost 14 psi. I have no idea how much boost it'd spin @ 52,000 on my EJ25 , but I bet it's a decent amount. Right now I'm hitting ~12 psi with a slipping belt on a Raptor SC. Vortech' step up ratio is higher so a bigger pulley would spin the SC the same speed.

Dude. Don’t mean to be rude... but I’m pretty sure most (if not all) of your questions already have answers on this forum in the relevant threads, or other similar forums.

And as others have also posted, the hardcore focus on a HP number isn’t always worth all the effort. (For e.g. just put the same car on a different Dino, on a different day, and you’ll get different numbers).
