Silver Bullet
 

Hey Guys,

Its been awhile since my last post. Between all the different types of turbo kits and massive amount of engine builds. what can I say Business is....GOOD!!

I was able to get a few more Z's in and we finished the remaining Jigs.

Here are some pics of the car we just finished today. Tuner Kits are available!!

How does the compressor/turbine housing impact AIT's?? It seems awfully close to that intercooler pipe.

When will the website be updated to reflect the tuner kits that are now available?

Valpozguy's motor blew with this kit on it. He was very vague but can u elaborate on what happened?

It doesn't how I know this is from the data logs from the Dyno runs. The AIT's stay within one degree of each other. Besides the charge air is moving so fast it cant absorb.

Well boost is boost regardless of what turbo kit you use. Well we tuned that car over a year ago. Some of you may know once you tune a ecu it never changes. only mechanical.

So it could be a wastegate malfunction or a boost controller malfunction or a bad tank of gas.

We had a single turbo G37 that drop it valves and he had the same symptoms before it destroyed itself. keep in mind they are high compression engines.

So is that 2 motors that blew with the single turbo kit???

I know all the problems that could come with boost.
One has to think there might be a problem with the design. Perhaps more r&d is needed.
2 motors in such a short amount of time.

I know nismo370 I think is his username is goin with a big single turbo for his built motor. I'd hate to hear his motor pop in jus a few months.

While S&R's response does suck in clearing anything up I'm pretty certain one of the cars that blew was pushing over 580WHP on stock internals, can't blame them for overpowering the engine. Assuming my memory is correct on this.

Yeah there was no mention of how much boost those blown motors were playing with

Valpoz was AT. I'm sure he wasn't anywhere around 580..
The response was disappointing. Unless the owner wanted that much power I'm not sure why they would recommend going so high on a stock block.

The car is a 1000 plus miles from my shop and i can't tell you what really happen to it.

When the car left the shop it was below 500hp.

Well the G37 dropped a valve while driving down the street with his wife in the car.

R&D is needed? So, GTM, Greddy Momentum, Stillen, Boosted Performance and every other forced induction kit on planet must produce a different type of boost? So, i guess I need to call Precision Turbo and ask them why the laws of physics ceased to exist in there turbo..lol

Honestly if youre that worried about a blown motor that is running double the stock whp and torque then you shouldn't be looking to do a turbo project. Just think about that...These cars generally make about 270whp and 240tq stock...most turbo'd 370s put about double that down 540whp and 480tq. Most run it reliable but expect issues when pushing double the power.

There really isn't much wrong with VSR's kit. There are a few little things I would and AM doing differently but it would really just be nitpicking the kit.

Lol, I am boosted. Stage 2 TT. 12lbs at 540/500..
There's always a chance for detonation. Everyone knows that. Just going with common sense or the "trend" here. 2 motors in short amount of time from the same kit. Seems very odd. Maybe in the design, tune? Something doesn't seem right from the outside looking in.
Researching STS or GtM or Stillen, can't find anyone that had blown motors so soon after. I've been runnin boost on the VQ for years now. Jus callin it how I see it. Hope it was all just a coincidence.

You're on factory internals? Didn't realize anyone was pusing that much power on stock internals.

The biggest factor would be the tune not being stable. I imagine these two blown motors are not local? Local fuels can be quite different and effect a tune especially with E85. Also climate and sea level can as well. We also cannot be sure what boost they were actually running at the time...EBC's make it really easy for people to push too much. I wouldn't say that it is an issue with the kit. More or less the tune or user would be the more likely problem.

There are a lot of 500+ people here...

http://www.the370z.com/forced-induct...ed-builds.html
Yep, just a quick look I see 8 minimum over 500HP.

Also, SRPerformance, check your PMs. I want to finish the forced induction noob thread & want to make sure your info is accurate.

That is what I was thinki. S&R did the tune and perhaps thats the problem. As u can tell there's plenty of people pushing 500. This motor is stout and should hold much longer than these 2 kits did.
Just trying to make the community aware.
There's too many boosted cars out there to attribute to "bad" gas although it could be its highly unlikely.
Either tune/kit something might be off. Not trying to put S&R down jus tryin to maybe get u to look over something again.

Because if it isn't in that thread it doesn't exist :icon18: Seriously there a lot of people on here who don't post but every once in a while that probably aren't even in that thread.

I know 2 people running that local that aren't even on here and I am sure there are more through the US.

:wtf:
I am agreeing with you, saying that there are at minimum 8 at quick glance plus more probably. :facepalm:
I never said that was the full list of boosted 370z cars, it is a user database kept up to date as best as I can.

Yeah I am thinking it is the tune as well. Only reason I brought up gas is...atleast this is the case around me the E85 blends change depending on the time of year. So when your running a tight tune it can cause issues. I agree though there is certainly an odd trend developing around this kit. Hopefully VSR can comment soon.

ohhhhhhhh. My bad bro. My interweb skills are lacking today :ughdance:

I really thought you meant there were strictly only 8 builds. :roflpuke2:

If you do know plenty on their build post it up in the thread, will just call them unknown, I browse around now & again to find some online not on this forum.

Yeah there are some on the NICO forums and stuff like that. Ill try and gather some details...hopefully mine will be added to the list here in a month.

Lets get a couple things straight.

The G37 is a local build and that guy dropped a valve THAT HAS NOTHING TO DO WITH THE TUNE.
We have tuned well into the hundreds of Z's & G's and not have any blown up.

The truth is and i didn't want to throw any one under the bus. I installed a manual boost controller on his car. He raised the boost level after he left our chop at Z1.The tuner at Z1 even verified that the car was in great condition. Besides his engine blew up a year later. Again tunes do not change However mechanical can change. The customer also stated right before it blew it was running bad some hesitation and he decided to punch it. So there is no way this our fault

The G37 had a new engine installed by Infinti under warranty (don't Ask) and the tune is still on the car AND the car driven daily and beaten at the track. This car makes on 100 octane 658hp

We have done over a dozens of single turbo & Twins. If there was a issue the car it would have not made 14hr road trip back home beating it all way up north.

Like how everyone speculates or diagnosed the problem since no one has seen the car.

Can u blame anyone? Ur original response was vague in clearing anything up.
Where was this reply the other day when people asked? Smh

I will like to add that at 12 psi on these cars is pushing the limits of the stock block, this is from personal experience of a friend's car. The car had a stage 1 GTM the day before it died it maid 550whp on a dynojet. The car was driven hard for 13k miles and holds the mph trap speed record of 127 mph. I also know of 2 GTM kit's in the area one blew up and the other was caught just in time. Both of these cars have built motor's in them now, basically what I am trying to say is you just cant blame a kit things happen.


Like someone else pointed out in this thread double the power of the stock block.

Yes I know the potential of what can happen. Never know when it can happen. Now there's plenty of variables that come into play. Gtm is a proven kit that's been in VQ motor for years. There's faaaar more Gtm kits out there than SR kits. If I'm not mistaken I think I only heard of 3-5 MAX that have this single turbo kit? I think the number is far less. So this kit is fairly new. With 2 blown already. Doesn't look good. The response from the owner doesn't look good as well.

The last one to blow was not runnin high HP number. See where I'm goin?

Lastly. U said the one G that blew had numerous track and driven hard 13k miles. I'd be happy gettin 13k the way I drive. Valpozguy had no track days if I'm correct and only some spirited driving.

Just seems suspect on the out looking in. That turbo does look real close to the piping. Just wanted to bring to the owners attention maybe he can look into something that might be an issue or the tune might be off. The way he responded says a lot. I hope the fellow member goin that route with his built motor has better luck

It was a 370z nismo that blew up and lasted for 13k car did 11.7@127 and is on my youtube channel.There is also another nismo owner that only lasted a few months that blew up. Now when I say blew up I mean rod out the side of the block. Then you have Sharbycoop who has the G 37 that caught his motor just in time before it shot a Rod out the side.

Now I don't want you to think I am defending S&R kit,hell I don't even like design of it.
I am just trying to shed some light on the fact that these motor's can blow up.

Also you cant count a dropped a valve as part of this hell I can drop one in my built motor I am still using a stock head.

Here is a video of the pull.

I truly think S&R builds a responsive and responsible kit. Obviously the sky's the limit on how much power you wish to produce. He just allowed that they got 658hp out of a stock block with 100 octane.

Now that's on the edge, and the same person made 647hp before his valves came raining out of the stock block. (I know who he is and he's very selective about what info he lets on about on the forums or otherwise. Claims all is well from the first build. Says he hasn't gotten to the track yet. (He's gunning for me.) I was told privately otherwise. Some people don't show all their cards.)

Mr. Squeeze is right on: Mine detonated @ 590whp and bent all the rods. Fortunately that's ALL that happened. Whew. (New tuner = safer tune = less HP =quicker ET. Go figure.) I have rods, pistons, studs, balanced, etc. now. Built and with more room to go.

My point is, it's out of control of the shop what the limits are if the boost is available to change. It's like giving my ten-year-old the cookie jar and informing him to eat only one every hour. Ummmmmm..... :yum:

That said, the dyno is easier on the engine than the strip or highway. Tread water carefully above 550. ;)

Good luck with this kit. It looks well made and in the right hands will last forever.

Coop

whats the cost of a complete install and tune?? Pm me the details please
