Jackson Racing Supercharger Owners Thread

[ojuniour]

I've read through every pages spanning 2014 till present.. and I've doubts back and firth so I decided to pull the trigger.

I'm driving 2017 BRZ AT and it's my Daily.
I would like to have power No MORE than 300whp while keeping most things stock.
I'm currently running JDL UEL (ceramic coating) and catless resonated front pipe - basically straight pipe. I've been on ecutek flex tune [for about a year now]...so I do run e85 very now and then (more like E70 in my area doesn't really go above that at most)

I won't be doing much of any track or auto crossing (so basically 99% street driving)
Question is what kind of power would I be getting on 93 tune (with stock pulley)
and running between E60 - E70 with my current setup?

I've read you won't need to swap out Injectors or fuel pump when on pump gas.
I'm most likely going to upgrade injectors anyway based on my reading..but since I might be running ethanol on several occasion while trying to tamper the power @ or below 300, would I still need to upgrade fuel pump?

Thank you.

From my experience and what I've seen 93 octane on stock pulley is in the 280 whp area. No pump or injectors required yet. On E70~ around 320 whp is my best guess. You'll need at the very least injectors. The stock pump can probably handle this on stock pulley for a while but it will definitely put a lot of strain on it. I'd recommend doing the pump as well for peace of mind.

From everything I’ve read you should probably upgrade to a higher flow pump since you need to flow something like 20% to 25% more fuel when using ethanol (others will keep me honest here). Starving your engine of fuel because you don’t have enough flow is apparently pretty bad and can result in engine damage. I suppose you could tune it so that your not over working your current fuel pump on ethanol, but I would expect you’d be leaving some power gains on the table.

Even though I'm only gonna be running E70 like once every other week or so?
Alright.

It doesn’t really have anything to do with how often or seldom you use ethanol. An experienced tuner might have a more technical answer, but I believe the idea is that if you are pushing past the flow limit of the fuel pump on ethanol, you might end up leaning out the AFR which I believe leads to detonation. Do that enough and the engine goes boom.

Alright.

If you try to lift more weight than you can safely carry once every other weak or so, will it be an issue?

Yes absolutely. I basically lift things up and put them down.
Ok for real I think I might as well..
I'm guessing I went be needing catch can also and oil cooler. I do have the oem 'foster' install currently... Not much but brings my temp down about 8 to 10 degrees..

Exactly.

Do it right the first time, or you may find yourself doing it over and over, and wasting a lot of money in the process!

What is your experience with the jackson racing compared to edel/harrop?
low/mid/high

A lot. I suppose you could say very high.

I meant in regards to power delivery for street use.

I'm not sure what you're asking.

My experience with the power delivery would be the same as everyone else who also has a Jackson Racing/Harrop/Edelbrock kit.

I do have a "high" amount of experience with all 3

Ok Apologies for the confusion. I am asking in terms of street use which one is favorable long-term-wise at 300whp max? and How the low/mid/top [end] ranges fair in comparison

They all build boost somewhat linearly, and with identically good tunes, will all be roughly identically reliable.
