KMO43

I bought the K04r because mine went bad. I have read that first gen ZFRs did fail and see a blown one every now and then for sale here but It's all about your goals

For me I'm going with a 7163 next year and I know I can sell my K04r to a bunch of locals here if I want to because everybody is so impressed with my car

i am running 26psi on k04r, i think KM043 was running 28psi

KMO43

Nope 28psi but I recommend 26psi.

I'm tuning that guy on 26psi running 91 so you'll be very interested in those gains

Yup! I have meth so it keeps my IAT2s totally in check

nathan112i

mine will be installed this winter i cant wait

KMO43

Your meth?

Ohh cool lol well if my turbo holds up ill probably wait for that new turbo or maybe i could get the current zfr for cheap brand new

dearbryant

yeah im the one getting tuned by KMO. Im on 91 and i have the k04r but just waiting on the gaskets and i'll be installing it the following weekend. KMO will post my logs since he has the before and after. (And im wayy closer to sea level then KMO)

I plan on going e47 after and see the difference there too.

KMO43

I think you'll beat me by a lot on e47

Ill be on 91 too so thats perfect haha if it works like im hoping, get the k0r4 then hp tuners then im set for a little while atleast lol

KMO43

It's more fun I rev it out to 6500rpm without just watching my boost gauge drop so fast and knowing all I'm doing is losing power

yes i am still waiting for a part in the mail so i can tap into the stock charge pipe. my local auto parts store was selling 1 gallon of methyl hydrate for $8 so i picked up lots.

28 psi on k04r or w/e is harder on the motor and trans than a zfr at 24 psi.

but I dont know what I'm talking about. I have 100k on my motor with the ZFR, stock trans and clutch.

KMO43

That's a good deal I usually pay just over $10

Why do you think I have recommended 26psi more than once in this thread???

But not the trans the ZFR will make more torque longer without a boost ramp than the K04r

True.

I wish I could see some flow rates for it.

KMO43

For the K04r?

I run 28psi knowing it'll be putting heat into onto the piston and rings but I run a ton of meth prob too much and haven't had any problems. Without meth I ran 26psi

Yeah do you have an HP log I can look at?

KMO43

Not mine because of my meth but I will have a 91 k04 vs 91 k04r in a week or so

I wanna see how good the difference is

KMO43

I will do a log with just adjusting the fuel trims no tuning to see the difference then I'll add some boost and timing and see what we end up with. Bryants turbo does drop a lot of pressure at redline way more than mine does and I'm at altitude so I'm expecting some gains on the same tune

Cool that would be great to see.
