Nw vq37 tt
 

Hello,

First post over here, but am looking all the time as the FI chat is alot more active than on Myg37. Anyways, I have a G37 that has been down at GTM getting thier TT kit installed. There are a few new items that will apply and lend more info for the 370 too so I thought I would post up here as well.

I have not seen any FI installs from up here in the NW, so I thought I would post some pics of mine. The car is still down at GTM, but is up and running and will be on the dyno for tuning next week. I have an appointment for September 3rd to fly down and pick her up. It is mostly a standard build but with a few different items - here are the specs:

The Standard Stuff:

GTM Stage 1 TT Kit
Ceramic Coated Turbines, Manifolds and Downpipes
External Wastegates and Down Pipes
No Cats
3 Inch GTM Exhaust
HKS EVC Boost Controller
Heavy Duty Oil Cooler

Some New Stuff:

Kinetix Intake Plenum
GTM CarPC Monitoring System
Synapse Engineering Syncronic BOV's

Here are the pics that I have so far (couplers & hoses are getting changed to black) - More to come

Very nice setup! You going to have a before and after dyno of the Kinetix manifold?

results?

Goes on the dyno next week with the new set-up. Will have results up as soon as Sam sends them over...

Can you give more info regarding the intake manifold? Were it's runners optimized for FI?

Can't really give any more info as I don't think there is any. I am kind of the guniea pig on this one. Not counting on any gains but hoping...

It looks gorgeous, but when I had my 350z on the old Vq that thing was horrible. It truly looked amazing, but it lost power, and tuning on forced induction was horrible.

Yeah, worst case we can just yank it off and put on the stock plenum. Also, I just got an email from Tony at Motordyne saying that they are in the final production of thier intake plenum for the vq37, the M370 and that it will be out soon.

Any info on: GTM CarPC Monitoring System
Pictures, what it can monitor?

It was first done by a member called Modme on Myg37. It is a windows based, solid state mini PC that fully integrates with the stock display (touchscreen enabled too). It monitors everything the HKS camp II does plus AFR. Further, you can choose different skins for the display, use the PC to store music, videos etc... This is the first car GTM is installing it on and will see if it is viable to release as a product..

Interesting, now I want to know even more.
What version of Windows?
What did he use to program it?
Does he plan to support more than Nissan/Infiniti cars?

I love that Upper intake

Windows 7. There is a program called Dash Command that interfaces with the sensors and provides the GUI. Can't tell you about other models of cars, but I would think it can be used across many platforms..

wow looking good! can't wait to see the dyno numbers!

Unless that was designed on a flowbench or you have before and after dynos N/A, I'd start looking for an OEM IM to put back on just in case...

Would love to see the setup in person. A growing number of NW people meet at the Tukwila Borders/Starbucks parking lot on average once every two months. Do a search on Seattle Area to find the chatter.

Will do - would like to see what other people in the community are doing as well....

Will have the car back in a couple weeks and plan on bringing it out.

Thanks for the info, Greedy. +1 rep :tiphat:

Update:

Just talked to Sam and the car is finished! Heading to the airport in an hour and am picking it up tomorrow morning. A couple of issues came up:

1. The Kinetix Intake Plenum has proved to perform just like the old ones for the vq35's - like crap. The TQ curve peaked then fell off and was causing some other driveability issues - Put the stock plenum back on and all is good.

2. The Synchronic BOV's that I wanted to try out were causing problems with the MAF readings at idle - I had them put on the tried and true Tial's.

3. The car PC monitoring system that Sam wanted to try out ended up not working. His install guy left mid project, so he intstalled the Blitz system. I will run with it untill something better comes out.

The numbers were good with the above stuff on there (500hp, 450tq), but will be on the dyno today with the stock plenum and tials on and improve on those numbers.

I will be driving back through vegas then back up through Utah and Idaho this weekend and let you all know how it does. Can't wait until the morning - feels like Christmas!!

Nice! As I suspected on the intake mani, though... :(

Did they try the SB001.5A anti-stall valve kit on your Synchronic BOV's? I don't have any direct experience, but they're supposed to help with idle on VTA MAF-based setups.

aww i was looking forward to seeing the monitoring system :(

Not sure honestly. I am taking them home with me though and may try the anti-stall or recirculate them into the cold side of the turbos.

Heading to GTM right now!

Just a little update, he has been on the roed for the last couple days, posted this yesterday on the G37 board .


And here is the before and after dyno

At what psi?

10.5-11psi.

It got colder in Oregon and north on the drive back. It pulls alot harder in 60 degree weather and the temps are nice and low. The intercooler seems to be very efficient as the IAT's are about 10 degrees over ambient after 3 good pulls. Oil temp hovered around 180-200.

Sounds good man. Can't wait until I have the money for a TT setup.

I think they're priced about right, but priced out of my league at the moment.

I was going to say the BOV looks and is named like a totally cheap HKS rip-off. If you want a pull type valve just get a real HKS Super Sequential. They're really reliable. But, it sounds like you got a pull type Tial wich is a respectable brand so I'm sure you will be good.

It looks great, nice power!

The Synchronic BOV is so much better than any POS HKS. I've had HKS BOV's on both my Evo and Galant turbo cars, and they suck. Period. Recirculated or not. Across the entire factory-turbocharged community, you will find nothing but dissatisfaction with the SSQV. The TiAL BOV's are also a much better choice than HKS units.

I like my HKS SSQV's

lol Lou, I knew you'd have something to say.

I like(d) them as well, but it's common-accepted truth that they're not healthy for high-volume turbochargers or even some stockers - they cause unnecessary compressor surge/flutter in some applications, and quite often leak under high boost.

2 SSQV's is actually a really good setup to eliminate flutter and surge (plus it sounds bad ***), but I'd still rather have something else if I were parting together a kit.


My point is: Synapse Synchronic BOV's are indeed legit. I wouldn't call them an HKS knock off at all.

Subscribed... :)

I also have a 2008 G37S, and I'm about to order the same kit. Looking forward to continued results. I have an auto and so I'll need a few supporting mods in that department, but it sure sounds like it's a go. Thanks for the post. :tiphat:

Regarding the Synchronic BOV: I had a Synchronic on my Subaru STI and after changing and futzing with settings, it worked PERFECTLY. Yes, there are a few adjustments, and you DO need to plumb back into the intake, especially with the MAF. It is quieter if you do so, too. (For me: A good thing. Others: Not so important)

The low throttle response was immediate and gave zero flutter, which I couldn't lose with the TIAL. I'd be giving those a try once again. Glad to know the TIALS are OK, though.

Don't know anything about the other brand.

Jim

I have the Synapse bov's and another set of upper charge pipes with the Synchronic flange welded on, so I am going to try them again either with the anti-stall kit or recirculated. I am getting a little compressor surge at very low boost levels. I am going to try to adjust the tial's first and see what happens.

There should be no need to recirc; your setup is a blow-through hot-wire MAF setup and your BOV's are prior to the MAF. It might just take some adjusting and whatnot - I know the Synchronics are picky about the vacuum line plumbing.

Here's a few more shots from the trip....

Let me guess this happens at very light throttle as well?

No - none when any throttle is applied. Just when in first or second and getting up to about 1-2 psi at 3k then shifiting. It's only a quick, momentary flutter that sounds like a little surge. Any more rpm's or boost and it blows off completley.

I am not familiar with the spring tuning on the Tial's, but I understand that's a source to look into for the cure.

That flutter was consistent and annoying on my Subaru with a Tial, and my experience with the Synchonic ended up curing that. 95% of the time we are at low throttle and boost.

Looking forward to your experiences. Thanks for the updates.

Subscribed for results! Would love to get more info on the intake manifold.

Nice number!:happydance:
