That's the valve fluttering. It probably needs spring adjustment, though I don't recall whether that tial BOV can be adjusted like that. I am kinda surprised they didn't use HKS SSQVs. I feel like those are a preferred valve. I hated my Tial BOV on my STi and took it off for something else.

While the HKS is certainly good, TiAl makes the best blow-off vlaves and wastegates money can buy. Their BOV also has a significantly higher flow-capacity than the SSQV.

What are you going to due for timing? The cobb isn't allowing the G37 guys to actually pull or add any timing. With the stock CR you are going to have to pull some timing.

There are a few ways to achieve desired timing...but the provided combustion duration maps alone arent enough....We have been working with the 370z timing system a bit and have a few methods that will be implemented along with the Access port....

Yeah, I liked my Tial wastegate, though it did start to stick after a while (but they rebuilt it for free). As for the flow, I am guessing that's why people often run 2 HKSs, like on turbo M3s. There is the matter of the sound it makes too--not everyone likes it.

^^^ sex to my ears!

here are some pics, results were 434RWHP at 7.5 psi on our Mustang dyno, so about 475-480RWHP on a dynojet

I got my money on the kart!

have you posted a dyno chart? I am currious as to torque, specifically low rpm torque. Looking to compare it to a s/c.
thanks
john

I will post up the dyno later when I get to scan it.

The curve is pretty flat all the way across with max at 333RWTQ on our dyno or around 370RWTQ on a dynojet

...The car did really well on the dyno...I am very impressed how well this setup performs and drives...drives like stock until the turbos come on...and they do come on quick!....the sound with the open wastegates is phenomenal in boost and quiet through the 3in custom X-pipe implemented during normal driving...all I can say is WOW...this car feels like it should now!...more vids and pics on the way...stay tuned!...:driving:

Having owned a 300ZXTT with aftermarket turbos etc. 7.5 lbs seems low. The HP looks good. I'm assuming the 7.5 is for reliability with stock internals, correct?

Is there space for the Stillen Gen 3 intakes?

Good Job guys, Very clean :tup:

Sam

well the VQ breaths way better and has higher compression than the VG, having owned one you will know that you need about 20 psi for the same numbers we got with only 7.5 psi on the 370Z, this put the horsepower where we felt comfortable with on a stock block, it was almost doubled from stock.

don't want to find the limits on a customer's Z

no, there is so much piping that the G3's cannot be there and are not the right shape to get to the turbos if you want to use them as intakes

congrats to the owner and you guys for putting this beast together!! looks amazing. he put some money into this car...rims, s tune, now the turbos!! i like alot. which turbos did u use from GTM...i know theres like a turbo option when u buy the kit.

Any chance we could see the release of a kit which doesn't maintain stock drivability and the turbos don't come on quick?

I like that torque curve. Is this on 28's with .64 or .86? Looks like the cobb did an excellent job for a/f. I am assuming you installed a tuner kit since you went with cobb. What injectors are you running?

Thanks, they are the Stage 2

LOL sure anything you want

with the .86 and we are Cobb Tuners

injectirs are 600cc

Just to make sure...this is the same setup that made 611 RWHP on the G37 running 12-pounds on 100-octane?

pretty much

Did you guys install the stage I (0.64a/r) or stage II kit (0.84a/r)?

:owned:

Sorry I missed on that post

Good job Horsepower Logic.

Questions:

How is the rubber elbow holding @ 7.5psi(the one on the top left of the inter cooler)?

Would that rubber hoes take the heat and abuse of higher boost in the long run with out coming off or get damaged?

Thanks

well tough to tell since so far it has only been a few pulls on the dyno, but it held up fine with no obvious bulging, if that is your concern, it is pretty thick and as for heat, it wont see any more heat than the rest of the plastic/rubber parts in the engine bay.

it is similar if not the same as the parts used in the Injen cold air intakes.

The OEM rubbers, plastics, and the Injen cold air intakes will never go throw the pressure that this rubber elbow will go throw.

anyway. time will tell. and this is an easy fix. exchange it with a metal elbow, for more reliability.

Peace.

here are a couple of more pics

well the VQ has .7 liter on the VG, 11:1 compression instead of 8.5. so thats where the power over the VG is coming from. ;)



nice install and power. i was expecting to see more though :(

So that rubber elbow won't leak air or come off under high boost?

What rims are on this car? They have a great look to them. Also great job with the install looks factory with everything bolted back up. Can't as for much more as far as fit and finish go!

If the clamps are on tight it shouldn't just like any of the couplings

They are Volk GT30 Phantom Edition

Not at all, not to mention that we supply T-Bolt clamps which are proven hardware for high boost applications

Sam

wow. that car looks a billion times better with the painted front. u should do the side skirts too

That front end looks effing amazing!! That is a kit from Nismo? What kit is it? Any pics of the rear?

edit: saw the other pics of a side view of the rear. Wondering if you can post a full view of the rear please?

very nice! are u gonna paint the wing and mirrors black too? or that may be too much. looks amazing tho. nice choice of rims

Keep painting things black and it will look like a bumper car soon.
