how reliable is the hf manifold? how much power/psi?
 

what power levels / psi are you guys making with the hf manifold? i have no issues at all about using it. but i want to know if i go to a higher psi (14-20) making 250-300whp, if it can take it. im hoping to pick up 2 soon. thanks

youre worried about the manifold failing or not flowing enough?...its not gonna fall apart when you hit 276.5 hp, dont worry. But id get/make a better manifold if i was making a serious setup like that

I'm hoping to make 250-300whp with it...and AC ;) Flanges should be done soon, just hafta cut and weld the rest. Right now I'm thinking no more than 200whp on 7-10psi stock z6, but I have nearly all the parts for a built sohc vtec with zex cam. Assuming I don't blow more than 1 motor, I'll be trying to convince LovFab to make a EQ-minime manifold that's AC compatible. This project is more about getting my feet wet while making a not-so-common setup. 300whp EF 4door w/AC & drag/autox suspension.

i was more concerned with it failing or cracking. i just won 2 on ebay. so if one cracks, ill throw the other one on there, with lower boost until i get a decent one made. thanks.

the amount of boost has no effect on the manifold really

I got my HF for $5.

I haven't found a reason to upgrade in the 2 years I've been using it. :6

better then a ------- piece of ---- ssautoslanteye mani

Re: how reliable is the hf manifold? how much power/psi?
 

yeah....i didnt even think of that....the pressure and power isnt really effecting the manifold that much. i would take an hf over ssauto anyday. thanks for you help.

Re: how reliable is the hf manifold? how much power/psi?
 

i'd take a port matched HF over a log manifold any day of the week.

HF over a GREEDY POS anyday!
