How long are you in Vegas? You know you can get pump 100 octane at certain Rebel Stations there!

So hows the exhaust sound with 2.5" + cats on turbo car?

No cats...test pipes. Well, I have 100 cell inserts but those are after the test pipes.

It sounds amazing...just very very loud! Thinking seriously about 12" resonators. I'll do some recording in the morning.

Hi all,

I have been seriously MIA on the forums lately because life, guys. You know how it is :P

Anyway, here is a mini review for you all. I received my FI car back from Tony in March, and I have since put around 8,000 miles on the kit. At around 9 psi, I'm putting down 500whp and 450 lb/ft on 93 octane pump gas. W/o boost controller at around 6 psi, the output is noticeably less but still far more potent than stock (obviously haha). I would guess around 380whp if my butt dyno is calibrated correctly. ANYWAY.....

On to the meat. This car is now certified monster status. VWs and Hondas hate me even more now and decide to release multiple beehives worth of noise upon sighting my Z. Do not, I repeat, do NOT engage. The turbos tend to spool up starting at 2500 rpm and really hit stride by 3k. There is ZERO drop off of power all the way to redline, which is extremely impressive. Very smooth power band. Whiteline diff bushings + 305mm Pilot Super Sports = Grip. I LOVE driving this thing, except for a few gripes, which I will address now.

Now, let's address something that almost nobody (probably) cares about who has put FI on their Z: gas mileage. I did a raw number tank-to-tank calculation, so this IS accurate. On 6psi (low boost), with about half city driving and half highway driving, I got a combined 19.274 MPG, with 366.212 miles to a tank. This calculation assumes a 19 gallon tank, even though most fills won't be that large due to the "emergency" reserves, which are roughly 1 gallon of fuel. For those of you who don't know, the onboard fuel computer is completely inaccurate once you swap out the injectors, which is part of any turbo upgrade due to the increased fuel flow necessary. My Z's computer said I would get 479 miles to the tank, and let's just say that number starts dropping real fast lol. I can safely say that consumption increases on 9psi compared to 6. I would guess around 17 MPG, but that number will drop very rapidly if you stay in boost a lot, which is the whole point hahaha.

Now, that all being said, I have a feeling the car is running slightly rich. Any time after letting the throttle off a boosted run, the smell of fuel quickly fills air when the windows are down, and my rear bumper repeatedly gets blackened (which admittedly looks kind of badass on red). AFR seems to hover around 10.5:1 under boost, which is safe (if not too much so), but the car has all of the symptoms of running rich: gas mileage drop, fuel smell, black rear bumper. I can't say I blame Seb for tuning it like this due to the unknowns that can appear from CA to PA. Completely different climates.

Along those lines, the F.I. exhaust is fantastic..... when the climate is right. I'm running 3" downpipes to a 2.5" CF exhaust with 100 cell HFCs. If humidity is low, the exhaust sounds godly. Just incredible. THIS is what it should sound like, and since CA weather is generally less humid year-round, I am going to assume that this exhaust was tuned for such a climate, hence it's legendary status. Once the humidity kicks in, however, the drone can be an annoyance. Above 3K it's totally fine, but 2K-3K is the killer. I was browsing threads and noticed that a member had a Helmholtz resonator fitted to his exhaust, which wasn't FI but a similar design. It eliminated the drone issue, and I have been exploring whether or not this is a viable option. Any input from Tony would be very appreciated.

No issues with holding boost using the Apex'i AVC-R controller, which I don't think anybody else has used yet on the 370z, so kudos to Seb at Specialty Z for dialing this in very well. Great controller.

So far, after 8K miles, I give this kit high marks. Very fun to drive, no major issues, and it puts a smile on my face every time.

Well done, Tony and the F.I. crew (and Seb). Well done.

PS Tony, I got your message and will try to catch you later today. Cheers!

Ninja Edit: Forgot Pics! I also have one with my gf but she'd probably cut my head off if I posted it lol.

Good stuff! now I'm worried about the weather here in dallas (humid 100+) lol. I wonder if the fuel will make a difference since I'm thinking about going e85. It's just a shame if I don't go e85 cuz there's a e85 station on every block here lol.

I am pretty concerned about your Z running rich. Running too rich is definitely not healthy for the motor in the long term. I do agree that turbo vehicles usually run richer than N/A but not to the point where you constantly get black bumper and smell raw gas out there on the back. Have you address this issue back to Specialty Z yet ?

faceglide · 08-12-2014, 02:46 PM

Haha, yeah hes the guy on 93! I even forgot about him, glad to hear you are enjoying it! Yeah, it is a pretty severe climate change for seb to account for, us California guys dont deal with 90% of the poopy weather you guys have to put up with.

Granted, his e85 tune on my car is spot on, the e85 scent with no cats is present on decel, but only because you can actually smell it catching up to you as you come to a stop, haha, no smoke, no fuss!

Excited to hear about the AT work. Trust me my friend, it is going to be absolutely worth it. I am envious already....having the TT and a manual means I spend more time shifting than accelerating on the street, WTB no-lift-shift without all the gunky traction control baggage! Or just an AT!

Arrvaxx · 08-12-2014, 03:22 PM

You're seeing poor gas mileage? I was getting 31 on the highway from LA to Minnesota which is crazy. I don't ever remember getting 31...even down hill...before.

Great write up. I have the richies too but that is the tune not the turbos. Planning on seeing Sebastian next time he's in the midwest to make a minor adjustment to the fuel map.

Eclipz · 08-12-2014, 09:14 PM

FI seems to be king of all twin turbo kits for the Z

Hotrodz · 08-12-2014, 09:36 PM

It's good to hear from you....outstanding write up. Mine is running a little rich as well, but I'm at 3500' so that is another factor to play into things. My fuel economy is never more than 24mpg on the highway, mostly 22ish and 14 or 15mpg in town. I attribute it to my driving style as the best I have gotten NA was 26mpg hwy and 17 around town.

1slow370 · 08-13-2014, 03:03 PM

^ wtf? are you thinking lean? all running rich will do is eventually foul plugs and o2 sensors. if he were running 7-8 to one then MAYBE he would have to worry about washing the rings but 10.5 isn't going to do any real damage. All he is doing right now is wasting fuel and losing power.

Seb@SZ · 08-13-2014, 03:20 PM

Jumping in to clear the "air". When Mike's Z left California it was tuned for high 10s and low 11s. His environment (altitude, pressure, humidity) will attribute to changes in the tune. With that being said 10.5 under WOT on a high compression engine not intended for boost is perfectly safe. On the other hand if your idling and cruising at 10.5:1 AFRs then there is cause for concern!

Another thing to remember is air is 500x times lighter than fuel so when you first hit the throttle you'll see transient fueling enriching quite a bit to account for the huge rush of air entering the cylinders. You may see it dip down but otherwise it will stabilize.

Brand new forced inducted vehicles, for example GTRs, EVO Xs, etc., have a nice soot build up on their tips and the bumpers get "coated" black even after a minor amount of miles. This is with them having two sets of cats on them still. I think Mike's post was taking way out of context and the way it was written makes it sound like something is wrong.

Correct -- thanks for clearing this up, Seb, and I apologize for any confusion caused. The black coating is nothing new. My Dad's GTR has a similar buildup but not quite as dark, but that is to be expected. Also, the exhaust tips with the Nismo are recessed due to the bumper design, so it's gonna get black faster than a standard Z rear bumper would.

Anyway, the 10.5:1 AFR is a stable reading while under WOT and full boost. Idle is right where it should be: 14's. I'm not concerned in the slightest -- you and the F.I. crew know what you're doing, and I would hardly peg 10.5:1 as off the deep end! That being said, I think 10.7-10.8 would help mileage, but I'm not sure if that's pushing the envelope too much. The tune is definitely rock solid. Another note with mileage, I had my turbo Mazda3 tuned to run mid 15:1s when cruising at highway speeds, which really helped mileage and didn't pose any issues on that particular car, but I don't know the ins and outs of how the Z would handle that.

Any other questions, post up and I'll try to answer them.

P.S. Yeah I took the Z34 PA plate

P.P.S. The F.I. oil cooler setup is incredible! I never top 180, even on 95 degree days. Granted, that isn't track driving, but I was hitting 220 before I made the switch, and that was N/A!

You know how it is :P Anyway, here is a mini review for you all. I received my FI car back from Tony in March, and I have since put around 8,000 miles on the kit. At around 9 psi, I'm putting down 500whp and 450 lb/ft on 93 octane pump gas. W/o boost controller at around 6 psi, the output is noticeably less but still far more potent than stock (obviously haha). I would guess around 380whp if my butt dyno is calibrated correctly. ANYWAY..... On to the meat. This car is now certified monster status. VWs and Hondas hate me even more now and decide to release multiple beehives worth of noise upon sighting my Z. Do not, I repeat, do NOT engage. The turbos tend to spool up starting at 2500 rpm and really hit stride by 3k. There is ZERO drop off of power all the way to redline, which is extremely impressive. Very smooth power band. Whiteline diff bushings + 305mm Pilot Super Sports = Grip. I LOVE driving this thing, except for a few gripes, which I will address now. Now, let's address something that almost nobody (probably) cares about who has put FI on their Z: gas mileage. I did a raw number tank-to-tank calculation, so this IS accurate. On 6psi (low boost), with about half city driving and half highway driving, I got a combined 19.274 MPG, with 366.212 miles to a tank. This calculation assumes a 19 gallon tank, even though most fills won't be that large due to the "emergency" reserves, which are roughly 1 gallon of fuel. For those of you who don't know, the onboard fuel computer is completely inaccurate once you swap out the injectors, which is part of any turbo upgrade due to the increased fuel flow necessary. My Z's computer said I would get 479 miles to the tank, and let's just say that number starts dropping real fast lol. I can safely say that consumption increases on 9psi compared to 6. I would guess around 17 MPG, but that number will drop very rapidly if you stay in boost a lot, which is the whole point hahaha. Now, that all being said, I have a feeling the car is running slightly rich. Any time after letting the throttle off a boosted run, the smell of fuel quickly fills air when the windows are down, and my rear bumper repeatedly gets blackened (which admittedly looks kind of badass on red). AFR seems to hover around 10.5:1 under boost, which is safe (if not too much so), but the car has all of the symptoms of running rich: gas mileage drop, fuel smell, black rear bumper. I can't say I blame Seb for tuning it like this due to the unknowns that can appear from CA to PA. Completely different climates. Along those lines, the F.I. exhaust is fantastic..... when the climate is right. I'm running 3" downpipes to a 2.5" CF exhaust with 100 cell HFCs. If humidity is low, the exhaust sounds godly. Just incredible. THIS is what it should sound like, and since CA weather is generally less humid year-round, I am going to assume that this exhaust was tuned for such a climate, hence it's legendary status. Once the humidity kicks in, however, the drone can be an annoyance. Above 3K it's totally fine, but 2K-3K is the killer. I was browsing threads and noticed that a member had a Helmholtz resonator fitted to his exhaust, which wasn't FI but a similar design. It eliminated the drone issue, and I have been exploring whether or not this is a viable option. Any input from Tony would be very appreciated. No issues with holding boost using the Apex'i AVC-R controller, which I don't think anybody else has used yet on the 370z, so kudos to Seb at Specialty Z for dialing this in very well. Great controller. So far, after 8K miles, I give this kit high marks. Very fun to drive, no major issues, and it puts a smile on my face every time. Well done, Tony and the F.I. crew (and Seb).

I even forgot about him, glad to hear you are enjoying it! Yeah, it is a pretty severe climate change for seb to account for, us California guys dont deal with 90% of the poopy weather you guys have to put up with. Granted, his e85 tune on my car is spot on, the e85 scent with no cats is present on decel, but only because you can actually smell it catching up to you as you come to a stop, haha, no smoke, no fuss! Excited to hear about the AT work. Trust me my friend, it is going to be absolutely worth it. I am envious already....having the TT and a manual means I spend more time shifting than accelerating on the street, WTB no-lift-shift without all the gunky traction control baggage! Or just an AT!

Mine is running a little rich as well, but I'm at 3500' so that is another factor to play into things. My fuel economy is never more than 24mpg on the highway, mostly 22ish and 14 or 15mpg in town. I attribute it to my driving style as the best I have gotten NA was 26mpg hwy and 17 around town. __________________ *Fast Intentions TT Installed and Tuned by Seb at SpecialtyZ 610whp 560tq:\|Fast Intentions 3" TT-TDX*\|SpecialtyZ/Fast Intentions 72 Row Oil Cooler\|SZ 6 Puck Clutch & Flywheel\|3GsCustoms\|Z1\|Wavetrac\|Hotchkis\|Whiteline \|Blitz\|Fortune Auto 500\|Fujimura\|SPL\|H&R\|TK\|TWM\|RPM Rollbar\|Sparco\|Next Level Performance\|TrackSpec\|AeroFlow Dynamics\|Pioneer\|

All he is doing right now is wasting fuel and losing power. __________________ ANSWER PRICE LIST Answers - - - - - - - - - - - - - - - - $0.75 Answers (requiring thought) - - - - $1.25 Answers (correct) - - - - - - - - - - $12.50

Seb@SZ Enthusiast Member Join Date: Jan 2010 Location: Chatsworth Posts: 277 Drives: Zs Rep Power: 25	Jumping in to clear the "air". When Mike's Z left California it was tuned for high 10s and low 11s. His environment (altitude, pressure, humidity) will attribute to changes in the tune. With that being said 10.5 under WOT on a high compression engine not intended for boost is perfectly safe. On the other hand if your idling and cruising at 10.5:1 AFRs then there is cause for concern! Another thing to remember is air is 500x times lighter than fuel so when you first hit the throttle you'll see transient fueling enriching quite a bit to account for the huge rush of air entering the cylinders. You may see it dip down but otherwise it will stabilize. Brand new forced inducted vehicles, for example GTRs, EVO Xs, etc., have a nice soot build up on their tips and the bumpers get "coated" black even after a minor amount of miles. This is with them having two sets of cats on them still. I think Mike's post was taking way out of context and the way it was written makes it sound like something is wrong. __________________ Z Car Specialists www.specialtyz.com Blog http://specialtyz.com/blog/
