Which HFC for a TT or SC Build
 

Hello my dear, supercharged and TT 370Z owners.

I have not found a proper thread where was accurately described,
catalyst which is best suited for the extra power in a more boost Nissan 370Z?

My problem is that the original catalysts for 5000 km already given up the ghost and the new Fast Intentions 300 cells catalysts also already broken after 10000 Km (loose in housing) are.

What catalysts can you recommend me for the extra power 500 HP?
What are you going and you have no problems so far?

Thanks for the answers and a dear Greetings from Switzerland :tup:

I'm still on stock cats and will be lookng for 500WHP on my set up.. BTW 6000 miles on my kit and the cats are fine.

We have a customer rocking the Berk Technology HFC. They are a well built product that have great flow. You can see some more info from Berk HERE. I recommend giving them a shot as they have great build quality and additional bracing to prevent cracking seen by some of the other manufactures.

Thanks,

The usual catalysts are operating normally.
We in Europe have very specific catalysts since 2010 (Euro 5)

The elderly would probably hold for a while....

Please report your best upgrades :tup::tup::tup:

Please in for more informations:tup:

I dont know about others, i just remember doing the research when I went to purchase mine.. To be honest with you, Fast Intentions is really good with customer service. If i were you, I would go and talk to Tony about the issue...
I stand by Fast Intentions products and service myself...

I have berk HFC's with the GTM Supercharger, 7000k miles, no issues so far.

You are going to continue to have problems with HFC's and forced induction. They aren't up to the increased pressure and temperature.

Fast Intentions has an option for their exhaust that puts a high flow cat further down the exhaust. This way it stays a bit cooler.

Random tech hfc's and ark exhaust and I hate the sound I am going back to stock cats my power will go down but I don't care I just can't stand the raspy popping sounds I get a low rpms car sounds good under load

People hate my car at 6am lol

Thanks guys for your answers! :tup:

I was in contact with Tony from Fast Intentions.
I will keep you up to date ....

Thanks for your support!

I've been told by multiple sources (Sam at GTM & Tony at FI) that the HFC cannot handle the heat/pressure of the TT setup (not sure I'd supercharged is any different) and they won't last. I'm thinking of resonated test pipes only because of this, but I don't want to add ANY rasp, just free up flow/power.

Motordyne art pipes :tup:
No rasp for me

Hey Guys

Thank you for your response!:tup:

Unfortunately I need a catalyst here in Switzerland!
If I get caught without a catalyst, the Nissan is shut down without compromise!
Bad laws here in Switzerland!:shakes head:

We will see what comes out at Fast Intentions ....
The cells are in a new 175 project off the supercharged world (SC & TT)!

Keep you up to date

Someone must make an aftermarket cat designed for FI that doesn't melt...

What have you heard about the cats breaking? Some threads about this have made me hesitant to pull the trigger

HFC were never thought about for FI is the problem. People who go with FI usually go with TP, RTP or down pipes because all HFC or even OEM cats will slowly be destroyed and could harm the engine.

You can talk to Tony@FI for a custom solution that will put the cats further away from the exhaust side of the turbos. The 3" TDX already implements this design for the cats.

I've been running the FI HFCs for about 21k miles now with my Stage 2 TT. Am I supposed to see or hear something? It's the same to me since the day 1 haha. Exhaust is even quieter now after getting the new transmission put in.
