JRSC vs HKS v3 SC
 

What are people thoughts on the different kits? They are both around the same price, but it looks like the HKS kit uses the stock intake/MAF? Just curious on people's thoughts on the different kits. Any advice would be appreciated! Pre-mapped tunes included are convienent and a definite selling point, but the JRSC doesn't seem to have one for the 2017 BRZ? Thanks in advance!

The HKS has no way of measuring charge temperature.

JR has been tried and tested with outstanding customer service. Only thing you hear about hks is there superchargers failing, with no customer service leaving owners stranded

Thanks for the responses. I decided on the JRSC, due to the above issues and the pre-tune won't work with my 2017. Thanks!

slightly off topic, does anyone knows if Jackson Racing finally issue the CARB tune for 2017 model 86?

Not sure on that, but a quick phone call or email to tech@jacksonracing.com could probably get that answered for ya.

I have jrsc c30, love it, so simple, so powerful. Near maintenance free, tents to eat a little of its oil tho so check it doesn't get low

Sorry to resurrect this from over a year ago, but can you just clarify why this is an issue? Is the IAT sensor located ahead of the supercharger, so then the ECU cannot compensate for additional temp produced by the supercharger?

You could also get a pipe fab'ed up with a hole for the maf, post intercooler & have the OEM mad location hole blocked off. Thoughts?

Precisely.

The HKS charge pipe has an added feature (boss) where you can make a threaded hole and add an IAT sensor for the compressed air:

These come standard with kits installed by GP Performance from Germany.

Otherwise, the IAT sensor is not part of the HKS kit sold by most vendors.

How difficult is it to use the 2nd IAT sensor with E.G. ECUTek? Would it have to be spliced in to the wiring for the MAF (which houses the factory IAT, IIRC), or is there some way to connect it separately?

It looks like the Edelbrock system also has the MAF (and its IAT) ahead of the supercharger and intercooler. Is this also a concern with that system, or have they addressed the issue somehow?

it s very easy to put an external IAT in the charge pipe and to scale it on tune.
