Are you guys running north of 600 planning on lowering the boost when it starts getting hot outside?

Has anyone put a lot of miles on this kit just to see how the long term reliability will be?

Terribleone(?) was the test car. I'd assume he has quite a few miles on it by now.

So far there are (3) E85 cars that have made well over 600 RWH. Most of them will "rarely" push it over 550 RWH.

We have setup custom maps with the boost controller and tunes to allow them to cycle through to each boost set point with one touch of a button. We went a little more in depth with each controller and that mapping from UpRev. For the sake of keeping things a secret for our tuner, I will not go into the specifics of what and how we do it.

Thanks, Tony

So now it's on the owner to be responsible and dial back the boost? That's got to be terrifying. :rofl2: You never want to go back to low boost.

Me and dirty are around the 3000 mark. I have been daily'ing the car in 80 degree weather on a 50 mile commute(each way) since Friday. Did my first oil change Saturday, clean as a whistle. The car is just as powerful as the day Dan@FI had me sit in it and almost **** my pants in it. So far, so good. I monitor Fuel Press, oil, water temps and oil press religiously....not a single fluctuation to date.

Are you getting an oil analysis?

I believe Hotrodz has the most miles at about 4,000. He is a 91 Octane car with very mild power (for now).

faceglide has put over 2,000 miles on his and he is one of the E85 cars.

Here is the bottom line...Efficient parts, adequate fuel pressure and proper tuning will allow you to push the envelope higher. Sure, is there a point where too much is just too much for the stock block, absolutely. That being said, up until our kit NO ONE was making these numbers on our psi levels, and to add, most people do not bring adequate fuel pressure to the equation. Lastly, we have one hell of a tuner who stops at nothing to make it perfect. It also helps that he tunes the Z34 almost every single day.

Remember, when we set out to do this we wanted to build not only the baddest kit around but it needed to be the most efficient. The results are a byproduct of the design.

Thanks, Tony

We do not give them the car back with 100% in it. About 65-75% and they can work it up from there as they feel comfortable. We educate all of our customers on how to properly use the boost controller.

In the end, it is there money, they are big boys and girls and they have to choose to be responsible. That being said, let's give people a little more credit once they have spent this kind of money to actually respect their investment/car and our time that has gone into it. So far, so good! That's the kind customer you will always want!

Thanks, Tony

And you've done that, and then some. :tup:

Now we're just getting curious where the limit is now. Everyone thought it was 450 ft/lbs or so. Now it's 100 over that. You've got guys knocking on the door of 700whp on a bone-stock motor. That's insane. I'll be the first one to run a victory lap if it holds together, and then I'll add fuel and turn up the boost. I'm really glad we've got people who are willing to gamble with their wallet that the motor can make big power. That's how we find out what it can really take.

I'm giving them plenty of credit, but I know how addictive boost is. :rofl2:

I have not put together a full-on build thread yet, but I will be shortly. I think it's fair to say the abuse I'll be putting the car through will be as thorough a test as anyone in terms of reliability.

That being said, I truly feel that most of the failures people have seen in the past can mostly be attributed to 1) heat 2) fuel, and 3) tuning. Not raw power. Are we approaching that point? Probably. But just look at the bottom end of this platform. It is no joke. Failures at ~500hp are not being caused by power alone.

I'll save a lot of the gory details around my goals, mindset, and decision making process for my build & review threads. But said another way, I went into this with eyes wide open. If it does fail, its because I chose to push it that far. This is why I have a spare short block being built in the meantime. I put my big-boy pants on before we started down this path.

Tony, Dan, Seb, & Charles held up their end of the deal (and considerably exceeded all of my expectations). Soon it will be my turn :driving:

:iagree:

Well said. That's how you have to approach pushing limits.

I'll be the happiest guy in the world if you figure out that the motor will take 700whp on a stock motor. If 700's the new limit, then I'll add fuel and retune and go looking for 600whp. Time will tell, and I wish you guys all the luck. I'm not trying to be negative. The results are fantastic. We're just curious where the new limit is, since the old one has been shattered into tiny, tiny pieces.

Every F.I. car has left with more power than the previous one. That's saying something. :tup:

Well said!

Well the response has varied and to be honest I really think the community should be excited as a whole to see the possibility for the z34 take on and crush the likes of the supra and most v8's.

No matter what is under your hood, you should be excited. With the advancements they have achieved in not only kit, but fuel, tuning, temperature, the vq37 is quickly becoming the most formidable thing out there under 50k all said and done.

Traction aside.

I was taken back by a few of the responses but for every doubter there are 10 supporters. I am just excited about the future and want you all to be too.

Its a double edge win. If it blows I get to chase 1000 sooner, if it doesn't, well the vq37 has stepped into a new realm of awesome.

Next oil change I will be inching up boost after an oil analysis. Sometime there I may take it to seb Or at least on the z car garage dunno just to get a good look at it with the added boost.

This will go on till next January where all bets are off and my built block is good to go.

If things pan out how I hear them to be...there will quite a few 850+up z's roaming relatively soon. What is there NOT to be pumped about.

This kit makes me wonder if it makes more sense to go this route than swapping in a high-displacement N/A engine. I'm thinking, for the track, No.... maybe someone who sees the track regularly will buy this kit and give us some results to that effect. One can hope!

You seem to think doubters are being negative and you're being defensive. It's not that, it's a genuine curiosity now to see where the limits are. Until the FI kits started trickling out, there was one guy over 600whp on the stock block and he was on C16 if I remember right. ONE. That limit has now been pushed much, much further out. But the question that immediately follows is "So, now that we know 650 isn't too much, what is?" Questions do not equal negativity.

We're not knocking FI, the kit, the tuner or your car. We're in ******* awe at how easily these things make previously unheard of numbers. Now we just want to see where the wall is. It's going to be a FI kit that finds it, since no one else is making that kind of power. Every car that comes out breaks the stock block record, and then the next car breaks it again. That's insane.

Damn there is never a dull moment on this thread is there. Definitely glad to be part of this group. :tiphat: :excited:

My car will be on the track every 2 to 3 weeks until late November.

You're going to make guys with some very high-dollar equipment feel very, very inadequate. :rofl2:

Fantastic! Keep detailed notes on what does and doesn't break on you.

I understand you're working on a build thread so I'll refrain from asking you about how you're doing heat management etc and wait to read it all in a thread. :tup:

Hear you loud and clear brotha! I think many of us are in clear agreement. Forum communication is just hard to extract emotion from.

This is just too fun. I cannot even write my review because I just love this car and cannot just resist taking it out and raping apes to stop and take a few photos and vids lol.

Got about 300 miles in my drag radial setup. Who wants some launch vids?

I better get them out before hjo steals my thunder. Excited for you bud!

Now we need Tony to start working on some magic part for the rear suspension that will allow any of us to hook up without ruining the handling of the car or ditching the rear akebonos.

Yeah some parts that reduce camber gain and bump steer in the back would go a long way methinks.

Problem is, it's gonna be a helluva job moving the suspension mount points to fix it.

Ugh. Don't get me started on all that. I am in love with the vq37, not so much the rear suspension.

I really want to keep 19s, if not 18s out back. Whatever it takes tho.

The current answer to making huge improvements in traction is nothing you guys want to hear.

RAISE YOUR REAR SUSPENSION! It will make tons of difference. I am going to prove it with 60' time comparisons on my 315 Toyos in a couple weeks here.

The relationship between the UCA and LCA in the rear of these cars is setup for major camber gain. To raise your car as far as your coilovers go wont even get you out of extreme camber gain, but it will help a lot. Raise the car, and stiffen the rear suspension (yes backwards from normal drag racing theory).

Justin and I have been playing with different ideas on making a bolt-in quick fix for this... but everything back there is working for camber gain and I am not so sure anymore than any little quick fix is going to help much. But there is one quick thing I want to try.

We tested a prototype LCA mount we made and it helped a ton.. but doing it with just that one arm (and keep stock arm length) we had to move it so far that it really ate up ground clearance and I wouldnt want it for street driving. Next up is to do a custom LCA with a different mounting location.

Well, what are you wasting time posting here for? Get to it. :rofl2:

If someone solves this problem, it's either going to be you, Tony or Sasha.

Will it fit G37 coupe?!!

I liked your initial response :p

Don't get upset if I break into fast intentions to take your car for a joyride before it leaves... I just wanna "test" everything one more time ;)

Taking the jet to socal....hey man, while you are "testing", wanna give me a ride home? 700 miles round trip, halfsies on the gas?:tup:

Hey...wait, wha?!

I'll take you back to NorCal if needed

It's for a good cause I swear!

Tony just ignore the call from your alarm company! :rofl2:

100% agreed! But after their much deserved vacations :tiphat:

hurry up with the drag radial vids!

Congrats FI TT owners. Really curious how this does on the track, I know DJTodd tracks alot and has an advanced boost control setup. Seems like it would be quite a handfull with that much torque on tap. Can't wait for the reports.

love reading this thread

awesome job:tup::tup:

Charles have you tried a SPL mid link setup (with SPL rear camber links), eliminating the eccentric toe bolt? You can get 0 camber even dropped a good bit and still keep toe in check.

Congrats to all the new FI TT owners. At a relatively low wtq value (gear dependent) the car is rwd traction limited. Getting to near 0 camber or sticky rubber becomes a necessity. Gears 1 and 2 remain useless for me with RE-11s and -1 camber. I also ramp up boost to prevent the wtq spike at 4k rpms. Will try 0 camber soon... And then go back to R888s if that doesn't work.

EDIT: just confirmed - SPL has the 370z versions...

This is the route I will be going soon. Hoping I can squeeze 325/30/19s at 0 camber. Might run a diff brace too.

If I weren't running true type rears, that's just about the only ones I would consider.

But, Charles is mainly referring to eliminating the additional camber (and toe!) created when the rear is compressed. Adjustable arms won't give you the ability to dial that out, just somewhat correct for it with more positive camber when unloaded. I think the route he is going is more along the lines of moving pickup points or redesigning the arms to remove any compression induced camber.

We really should create a separate thread for this and stop hijacking tony's thread though :)

Back to your regularly scheduled program.
