Any update on these? Trying to budget.. so many mods to buy, not enough money!

Still waiting on a 370z to test fit these and dyno the car @ H-Dev, anyone wants to help?

 

Car has to be stock / OEM ideally, specially the cats, 370z or 350z HR.

Time dependant I may be able to help. I’ve got a 2018 370 Nismo

Just seen this post , Ive been debating HFC for a while for my 370Z , my main consideration is I dont want the car stupidly loud 

 

I already have Invida CBE and Stillen G3 I want the gains provided by the HFC but not much more volume 

 

Has anyone tested the 370Z ones yet ?

 

Will there be a resonated HFC version ?

Hi,

 

HFC won't be as loud as the test pipes and virtually no drone either. 

 

These are being fully dyno tested on Wednesday next week and graphs will be posted here. 

 

No resonated version, won't make sense.

 

Let me know if you want to be added on the list.

Thanks for info 

 

Is it possible during testing to get some sound meter DB readings from stock to your new cats ?

 

I was looking at these reasonated fast intentions units but they arent cheap when you factor import duty

Update on this.

 

A new 370z 2018 Nismo was treated with a pair of TORQEN HFCs. The fitting and dyno mapping was done by @Jez @ H-Dev and here are the findings:

 

1. Perfect fitment, see photos below:

2. Noise level about 74dB at 4000rpm

 

video to follow shortly

 

3. Gains shown in the dyno plots below, 308 HP standard to 323.5 HP final, no EcuTek mapping,  15bhp increase!

 

a) Standard car

These will be going in production as early as next week, ready to take orders now, will PM you individually as per first post.

 

P.S.

Thanks a lot to the guys as Horsham Developments, as usual, absolutely faultless service, pleasure to collaborate with you guys! Thank you, @Jez @ H-Dev

DE version sample is in production, once it arrives here we will do the same dyno testing at H-Dev and update the thread, then move to production. 

 

We don't want to rush this project as we want it to be a perfect product! 

 

We're working on some custom crush gaskets too, 1.5mm or 2mm thickness. Depending on the outcome, these may become the standard gaskets the HFC are shipped with!

 

Thanks for your patience, guys!
