what video are you guys talking about

 

Watch the video and you will see what surge is...

They key word here is under load which his car wasn't. My bov sounded the same way. The previous owner of my car was telling me that I had surge until I took him for a ride in his old car after my boy and I fixed all the vacuum lines and leaks. You can only get surge under load(while the car is moving).

 

this is the video of bov flutter

And this is synapses video showing true compressor surge:

1SWTMAX was kind enough to share with us his project and people keep posting negative comments about his project. This kit is not put together with cheap parts. How can you say that when it has Turbonetics turbo tial bov and wastegate, and fuel controller. Plus R&D. MOst companies including vortech, kenne bell, paxton, stillen, etc. Use the same type of controller. If you want to see a cheap turbo kit look at Tsi kit($3000 for 50 horses). Thats a cheap kit.

And I know and hangout with guys who took their cars to a shop and said here is a blank check, I want 800 horses and they dont even drive or tune their cars. But the bottom line is this, it's a very good kit. And if I had a 5.5 or a 6th gen I would buy it. I am spending lots of money correcting all the problems with my car that has a custom turbo kit. I wish I kept my old 4th gen and just bought the Pfi kit...

Thanks to you 1swtmax. We have a turbo kit for the manual transmissin 3.5 Maximas.. Thanks and good luck. I will be following your thread..

 

Well let me take my hat off to you and say thanks. This hole experience has been good and bad. It has also taken alot longer than expected but I`m a pretty understanding guy. But at least now to the public a kit is available. He is fitting a T-62 turbonetics with a different hot side to mim turbo tag. turbonetics set this turbo up for Tim and I for the additional money I will hit 400whp, and then I`m done. Well , Tim is putting a Greddy boost controler in as well. And then I`m done. AND WILL POSTS DYNO SHEETS THEN AND NOT BEFORE. I am not posting something that my car is not.

And I called the guy with the Altima ( the one that you see in the video on speedforce racing) and he is very satified with the kit and says it runs great. So I don`t know why these guys are saying its a junk kit. I started this tread off thinking people would be interested but instead it became a bunch of b/s. So if you don`t like the kit don`t buy the kit. I`ve been talking to someother people in here and most of them told me that the tread would go like this. So w/t/f/e.

So I will be talking to you guys on thurs. (tomorrow) or fri. As long as he gets the new turbo in the car.

 

im sure the kit is great, i just dont agree with the turbo size. im sure for most people the management is more than enough, im more of a tuner kit kind of person so i hope that comes up. i just dont understand why such a small turbo is used. its a FWD car, so a little lag is a GOOD thing, with a t-62 and what sounds like a smaller hot side, youll probly be at full boost by 3500 and it will be out of efficient range by 5500. the TT kit for the z comes with t-61's, which isnt much smaller than a t-62, i would have expected something more like a gt35r or even a t-67 since its a single... i guess well see. i hope this kit comes out with a tuner choice for picky people like me, i bet it would sell really well then

 

oh yeah, and that car from the video isnt 1swtmax's, its from some toolio in NYC, he posted a couple times earlier in this thread (page 1)

 

Thats not his turbo maxima. Like ^^^ stated, dats someone elses....... He has his own cardomain site tho for those interested in seeing it. Its http://cardomain.com/ride/858544

 

Thanks. I was posting in nycmax and pasted the wrong link.. Thanks...

 

Well guys its going to be next week. The earthquake this week I quess was very close to turbonetics building, and postponed the delivery date. So it now looks like Tues.

 

i cant wait.

 

 

Really? I have a freind that live about 15 miles or so southeast of Alum Rock and Ive spoke with him a few times as I was concerned when I heard how close he was to the epicenter, said it really wasnt a big deal.Maybe they were closer....

 

5.4 is nothing special, but depending on the rock you live on and how far from the epicenter it can feeler stronger than it is. IMO, its just an excuse for them to be late

 

Yea, thats what I thought too. But I`m beeing told tues. now, so we will see.

 

Lol....yea man, could be but barring any earthquakes between now and tues they should produce something for ya.

 

Any news??

 

Everything is done now, larger turbo installed, gauges done, and greddy boost controler installed.

The dyno shop was closed thur. and fri. so its back to the dyno on mon.

 

I feel for you man. U just tryna have everything set up right before it comes back to PA and things just keeps on getting pushed backed. It SUCKS ***** BEING PATIENTS but Hopefully you'll hav your 400+ hp soon enough and prove a whole rack of people wrong

a larger turbo? will you be using a gt35r or something bigger?

 

So will the new larger turbo be required for the kit to come to produce the numbers anticipated?

 

thats the thing. if their stage 2 kit is advertised to produce those number you shouldnt have to put a larger exhaust housing on the turbo just to reach the numbers your were supposed to already get. For some reason his car isn't achieving the numbers advertised, so maybe just for this case its needed to made the power desired.

 

And turbo 4th gens, anyone who can handle installing even a kit should feel comfortable relocating a charge pipe.

 

You know, I really don`t know what he`s going to do with this set up it could be maybe a stage 3 set up for all I know. And we both can`t fiqure it out why my car will not hit the 374 as advertised, but turbonetics said this set up for sure will hit 400. Well of course I will still have my fingers crossed. But I should find out today.

 

I know I'm coming it late but is your car and auto od stick? Could have drivetrain loss also you could have bad compression on 1 or more cylinders. And do they claim this on whata oct gas?? 91-93 or 117 race?

 

ARE YOU Fin KIDING? Its a wonder that you didn`t ask me if its a 4x4 with 44inch tires.

Please start at the beginning of the tread and all questions will be answered. A leak down was done at beginning of project.

 

So dyno today or tomorrow??

 

in for the results and videos if available :-D

 

Was just trying to help It's hard to read through 145 replies at work.

Was hoping that it may have been something over looked. Oh is it AWD with 44 inch tires. LOL

 

so no dyno then eh?

 

Yea I know sorry about that but it seems like its one thing after another. But anyway with 44s on it should really hook up.

 

No, not today.(tues) But it is completly done with larger turbo, Greddy boost controler, 3-pode A pillar done and going to the dyno tomorrow morning. So I should know something tomorrow (wed.)

So with fingers crossed I should hit 400 whp.

 

So without trying to sound like a naysayer, what happens if the dyno falls short again? Is there some kinda plan b? Or lol kinda plan C at this point now seeing as though a larger turbo was already needed? I mean we all know a larger turbo or more boost isnt gonna absolutely dictate more hp so then what? Have you spoke to them about this possibilty? Is there any chance they will just go back to the original turbo that made 375(IIRC) and market it accordingly?

 

I agree. There was a reason why the original turbo/set up did not make the power it was supposed to make. It seems like they knew you were out for power so they decided they would throw a bigger turbo/AR/whatever to help you hit that number so that you'll feel satified. 400hp peak is okay but as Nmex would say its the area under the curve that is more important than peak numbers. So they took the wrong steps. Figure out the problem and correct it so you can make the power needed not slap a bigger turbo and hope to hit the numbers you want. I would press for them to figure it out mainly because this car was shipped out to them, once you get it back any problems are pretty much on you, if they were local, just tow it back to them and drop it off. See if you can atleast get them to fix the spikes you were getting. Putting a EBC is a bandaide and I wouldnt rely on that as a cure for the problem, cause that could resurface at the worst time....

 

Exactly why I was I oh-so surprised nobody was interested in the runfiles of the previous dyno that showed the 375(again IIRC).

 

we'll he never hit the 375, that is what the kit is supposed to make but he hit about 350. I'm not sure if he got the run files and doesn't want to post them, or if the shop never shipped them to him.

I think the dyno for the car that set the baseline for this kit is posted on their web site. I cant remember for sure.

Overall I still wish that we could see the dyno for his 350hp run(s). I can understand wanting to get to a certain power level before posting up, but with the problems that are arising, it would only be beneficial to post them up as we can give insight and suggestions that the shop might not have thought of.

I just hope they finish the the car, this has been a long time coming and I'm starting to wonder why is it taking them so long to finish this up, but you cant rush perfection so we wait twiddling our fingers.

 

Ok, just got on here and fully understand what you 2 are saying (mdeezy and godson). Here is the low down. And you both are correct, there is a problem. He went to the dyno today with everything done larger turbo ect. And the car still only hit 355whp. He hit 355 at 6000 rpm at 8psi. So he turned the boost up to 10psi and ran race fuel and still only hit 355 but this time it hit 355 at 4500 rpm. So right away Tim called and told me there is a cam timing issue. Cause after 4500rpm it just flatens off. He is telling me that there is a cam timing issue but I think I have the wrong cams. You see, 2 years ago I had JWT S1 cams installed and ever since I had my idiot light stay on telling me there is a misfire. So I took the car to another performance garage and told them to check this out and they did some calling back and forth to JWT and did the compression check as JWT told them to do because JWT said the motor was junk. That it was not there cams causing the misfire code. But the code was never there till I had there cams installed. And believe me I did everything possibel, raised the idle to 850 like they told me to do. Finally they stopped talking to my performance garage, and I got my car back with these damn cams in. You know the car ran fine, idled fine, ripped down the highway fine, roasted plenty of hondas fine, you see where I`m going with this. So I done nothing about the light, just left it on, it looks kinda nice at night with that damn orange light on. Anyway well its back kicking me in the but. Tim thinks its the cam timing and I completly think its the cams I swear I have the wrong cams in that car. He said his 350z puts down 480whp. he pulled his dyno sheet up and at 4500rpm his car is at 320 whp and I`m at 355whp so that is alot of power but it doesn`t go up from there just flatens off. And thats why he says its a cam problem.

So thats the story for now and I know you guys have alot to say. But he`s pulling the motor tomorrow and checking out the cam timing first and if thats ok he`s pulling those cams out and going up to see JWT and have them check by Jim Wolfe and see what is going on.

When it rains it pours. Man I hope this thread does not reach 10 pages.

 

Okay then that helps to clear things up. I'm not sure how the split box datalogs but if it can datalog timing that would be a plus. Sounds like you could use a set of stock cams in the car. If a large turbo is on and you're STILL only putting down 350 or 355 there is a huge problem.

There is a thread of the stock 3.5 timing curve, that compared to the curve you have now (again if the split box can datalog) can help to narrow down the problem. I wonder if he/they have tried to advance the timing a degree or two and see how it affects the powerband. If the split box cant affect timing (directly) then you might need something more sophisticated for tuning. As you get higher up in power you definately want to have as much control over your motor as you can.

From you explanation of the cams, it does sound like an issue that is now coming back to haunt you. I'm not sure how deep your pockets run, but I'd say throw a set of stock cams in there and see how the car reacts then. If it starts hitting the numbers it should have been, stick with them till you can work out which cams to get and why they are not working. It would be a days job to put a new set of cams in.

 

What he plans on doing is taking those S1 cams out and taking them straight to JWT and see what the specs. are and compare, I swear they were packaged wrong or took off the wrong shelve or someting. But he said Jim will replace them if I do indeed have the wrong ones ( at least thats what Time thinks he will do) and replace them with the correct ones. But Tim did tell me that he will give me a set of factory cams, cause he has several sets at his shop for my motor. And as far as money lets just say HOLLY SHIZ. Its lucking I have an understanding wife.

 

I can imagine it's another $1200+ just to take the cams out. Ouch!

BUT, I hope that's the problem. I wouldn't even mess with JWT cams; just put the stock cams back; at least those are proven.

 

i'v yet to see one post which showed a gain using after market cams. while i doubt these are a problem with you're turbo application i wouldn't be surprised if they were installed wrong. all aftermarket cams for the 5.5 afaiw shift the powerband up and thats all they do. unless you have serious na mods it's useless. even then the most an na 3.5 with serious mods put down just 300whp.

i guess your cams are installed wrong. or a boost leak.
