I did a little 1/4 throttle pull today just to check it out, and I know what u mean, the spool on this turbo is awesome. Idk if there is even need for ramping it. Sounds awesome as well. And thank God the bov opens right away, no flutter at all even at light throttle . and I love how u actually have to get into boost a little to make it open, now constant blow off at light throttle driving. That got super annoying after awhile. A lot more sleeper as well. Freaking tial bov is loud in harder boost though. I likes it

 

Engine looks great man my motor build is going some time down road but I can't wait

 

Yeah no ramp needed for this turbo. It comes in perfectly. And the TiAl BOV, yeah it works absolutely perfectly with the -10psi spring, opens right away and is very loud lol. Can't say I had the same good experience with the TiAl BOV on the EFR6758 or other small turbo, it was always a hassle getting it to work correctly.

I just had myself a little road trip over the weekened, sitting at ~750 miles on the new setup, still going good. Clutch still breaking in as a small 3rd gear pull slipped a bit on 23psi, but i remember my KY stage 3 took about 1,000 miles or more to break in and never slipped after.

 

Ya I had to use both stock and tial on zfr to make it kinda work right

 

Good news is that the clutch started gripping now pretty good. No more slips it seems, held a 3rd gear pull today on the way to work just fine. We'll see how it goes, I'm gonna start adding boost a little bit at a time, been at 19.4psi for awhile now (thats 0% WGDC with a 14.5psi WG spring). Then make the switch back over to E47 and see what she does.

 

Clutch is holding 20psi on long 3rd, 4th and 5th gear pulls now. Almost at 1,000 miles , she is running great, it's so nice to have peace of mind and new parts. More miles and more boost.

 

Nice that you are taking your time. Bet the power up top is crazy.

 

Well, not too happy right now. Turning the boost up to 23psi and the stage 4+ slips in 3rd and 4th at 4500rpms. about 1,200 miles on it city driving. I emailed KY and spoke to James, I'll just wait to hear back.

I always though full face clutches aren't meant for this torque but its stated to hold over 500ftlbs. I am probably making maybe 300ftlbs-ish with such low timing and boost on 93 octane. 20psi no slips in any gear all the way to redline, 23psi slips. Hope i don't regret not going with their stage 4 pucked or twin disk setup :/

As it stands right now i can't recommend the full face setup unless it magically starts grabbing, we'll see i guess.

Shame, my stage 3 six puck took everything the ZFR could throw at it on 26psi and e47. I may have learned my lesson about full face clutches and high torque.

 

TWIN DISC doesnt work on a f35 my too tall to bolt up
my buddies been fighting with them

 

On a side note, here's the monzo shifter from eBay installed with my redline goods shifter boot.. It's a Hurst copy. Some aluminum and some plated steel pieces, knob has good weight to it, I like it. Actually good quality and easy install, shifts are actually shorter. Worth $62 imho. My stock one got melted while oven curing the paint, it arrived second day too.

 

My work out southbend stg4 pressure plate with a stock disc held my HP for a year

 

This is not what I want to hear considering I just installed this clutch....

 

You might be fine, I'll give it more time and see what happens on mine, it seems others have been fine with way more power on this clutch. I may just have bad luck idk.

 

I've heard lots of good/bad on about any performance clutch made for the f35's. It's a shame when broken in ALL of the higher end clutches work like they should. It seems like someone has an issue with any of them, while others don't. Sounds like you did what you could to break it in right. I've heard of more issues with the ky 4's verses the 3's when the 4's are supposed to hold more power. And more have complained about ky's over south bend. Hope it magically starts working ok for you.

 

Should have just stuck an 'overrated' GMPP in the car

Guess i'll keep my fingers crossed and continue to break it in.

 

Best of luck man!

 

Baby the crap out of yours for at least 500 miles or more, I remember my stage 3 pucked clutch didn't grip until 1,000+ miles, but it never slipped after at all. I'm hoping that's the case with this 4+ as well.

 

I sure hope it does.
So far my lsj upgrade clutch hasn't failed me, but I'm also not counting on it to last forever. Has taken several 4-5psi launches at the strip loaded on the 2 step. But I'm only 370whp.

 

Spec stage 3+ full face held 450 ft lbs without issues. Rated to 550 ft lbs. A clutch should hold its rating regardless of puck or full face style.

Ive heard of more issues with ky clutches then any of the aftermarket clutches for these cars out there. I quit installing them for people after numerous problems with them

 

I've heard the same about ky. Many liked their 3 at lower power and jumped to 4's with bigger power, and some struggled mightily with them.

 

Second oil change at around 1,200 miles, oil looked completely normal, no glitter or anything unusual. So I filled it up one last time with conventional 10w-30, maybe go about 2,000 miles and then start with the mobil1 5w-30.

Still grannying the car around now, all city driving, clutch is feeling like its grabbing a bit more on release now and clutch pedal is a bit stiffer. I'll keep going for a while more before getting back into it to give it the best bet to be broken in. Its tough doing this, I haven't heard my wastegate open in weeks

 

But at least you know what it will be capable of.

 

Lookie what i finded lol. Sounds strikingly similar to mine :P Although I'm sure I'm not the only person to have done that to the intake manifold.

 

I'm feeling the same on mine as I break it in as well. Happy to hear you're seeing improvements. Gives me hope!

Definitely feel your pain though... I haven't heard my BPV in what feels like forever. Tired of people driving up my ass too

 

Idk how many miles Tom has on his south bend but he is already doing full pulls for me.
