Now you are saying the pressure would equalize, but EGT's would be higher, and because the EGT's are higher this would effect the A/F ratios? I would love to hear your "theory" on this one!

Again....wrong on ALL counts. Ever taken apart the turbos on a stock supra? One wastegate...front turbo (just one example).

Do your history on C.A.R.T.... cleary you were successful there and is why you are now making turbo kits for Nissans now.

Both pressure and velocity drive the turbine wheel (that's how boost creap happens). What function is it that you think the wastegate does? Dump velocity?

The engine doesn't "care" until the backpressure exceeds manifold pressure and what overlap "cleansing" capabilities it has. Pressure goes to the lowest delta, and manifold pressure (when higher than backpressure) pushes the unburned exhuast out during overlap so the intake charge is clean. Once backpressure exceeds manifold pressure the effeciency of the engine during overlap drops dramatically. I doubt that the back pressure at 7 to 10psi is ANY where near exceeding MAP. If memory serves, they made over 650whp on a single 35r with that kit (backpressure being the worst it could possibly get).

So what is it that you actually have here, as cleary you have NOT done your homework to back these statements.

 

CLEARLY the "Momentum" for Momentous autofarts is going backwards at this point.

Nice start though here on my350 way to show your "first hand knowledge" and really back it up with confirmed data... uh I mean... yeah.

Any plans on how to get yourself outta the hole youre digging to China right now?

Maybe Relentless, or VRT or SGP or MRC can help you out on this one... oh wait... yeah

 

You mess with Intense, you mess with all of AZ.

 

Oh our range goes much further than that sir but, yes the thunder has been called down.

Meh we've been in the industry going on 11 years now, we'll see how far the "momentum" goes for this new shop. LOL

 

This is humorous at best, you were taking specifics, and now are generalizing... saying "Flow" is like saying "color". WHich color? Flow is the result.

I'm not mixing up anything, you are. Sequential turbos are DIFFERENT than straight twins. The sequential turbo's on the Supra for example, block off one turbo completely, and force all cylinders through one turbo. Then when it's ready for the second turbo, the gate opens and the second turbo comes on line. There is ONLY ONE wastegate in the system and it is on the front turbo, and 3 cylinders feed each turbo.

Congratulations you found a picture of a modern C.A.R.T. engine... all you are trying to do now is divert from the issue. The issue is that you have NO data to back up what is actually going on, you start with specifics which you say are obvious, then you back down and start stating other theories and making statements of things that are "less desirable". I'm sure Intense can give you the pressure ratio's you are mentioning because they use ProEFI which uses Pressure ratio for it's load axis.

 

Scott / Ben Did you forget??

 

lol...take your "help" with you too

 

a single 38 wastgate for 2000whp, every thing has changed u old wooden shops !!!

 

 

this thread is soo funny. so many nuthuggers!

so you are saying given an option to have the wastegate after the merge so both sides of the exhaust flow even thru it, or place it on one side of the exhaust so its mainly dumping 1 exhaust, you would honestly pick the way PL did it?

not saying the PL way doesnt work, but why wouldnt you want it after both sides of the exhaust merge????

 

In a perfect world, EVERYTHING would be DEAD equal, and dead center. Things would be more asthetically pleasing, and these discussions wouldn't need to take place. However in a perfect world, we wouldn't be stuck with a V6, or 3.5 to 4 liters of displacement, turbo lag wouldn't exist, you wouldn't have to change the stock rods and pistons, or need to run race gas to make big power. However things aren't perfect, the Z was not designed to be turbocharged! There is next to no room for a "proper" turbo install, and I'll take a turbo placement that has a proper oil return so it doesn't smoke or require a pump to scavange oil return. If nothing else, the people that have these kits are happy, and have no complaints on how well they work. What else do you want?

Well. I don't know about you all, but I'm getting sick and tired of reading and getting calls about all of the PowerLab end users with bad wastegate placement, boost creep and boost spike... errr.. wait.. that's never happened.

Carry on!

Darren

Edit: We have a sale on PowerLab turbo kits btw. See my signature. Yes, I'm an opportunist at this point. What are you going to say now?

 

 

WTF are you blabbing about. I asked a simple question, which is the only thing being disputed on 7 pages of nonsense. Its not a perfect world, but apparently there are 2 options for wastegate placement.

Would you or would you not want the wastegate after the exhaust merge so that both exhaust paths flow equally thru the wastegate.

Simple question. The PL doesnt do that, the Momentum kit does.

Everything else equal, why would you pick the PL piping?

Did Intense test both ways and determine that a 1 bank biased wastegate was best? Did they do 7000$ in testing to determine that? Please post the data Intense!

Get real. It was the easiest place fpr them to mount the wastegate.

I dont know how you guys can hate on another kit when intense/PL didnt do any testing on wastegate locations either.

Hello pot, this is the kettle.....

 

Apparently in 7 pages, you've missed the point. The burden of proof doesn't fall on Intense/PL because mom motors is making claims/contentions that have no empirical/quantitative data to support it. The proof that the wastegate is in A correct place is the dozens upon dozens of end users who haven't ever complained or even seen boost creep/spike (as mom motors originally claimed without knowing it... and then back peddled). This isn't rocket science. The function of the gate is to release pressure, correct? Does it do this w/out creating any discernible negative affect? Yes. What else is there to discuss? PL wanted to route the wastegate into the exhaust (not dumping to atmosphere as other kits do) for a few reasons -- hence the placement of the gate in the crossover. It works, get over it.

We sold another PowerLab (G35) kit today actually and the most comical part of the sale was the customer discussing this thread. He said that the kit meets all of his requirements and that he knew that he could trust us for tech support down the road as we've been in business for 10 years now and a vendor here for 5. In the end, that's what people want: a quality, tried and true product and a company with long, positive tenure, transparency, and support. The various vendors here that have cut their teeth: Sound Performance, Forged, GTM, SFR, Injected, and AAM, would have been equally an option for kit and vendor too.

Please keep bumping this thread.

Darren

 

^ you are correct in all points. people want a trusting vendor as much as a quality product.

This thread turned into a witch hunt because another shop dare say that the wastegate location on the PL kit was not optimum. Just because something works in no way shape of form dictates its the best.

Granted, saying the pL wastegate location was very flawed (or however it was put) was not PC, its just as ignorant to say the mom. location is not more ideal.

neither company knows for sure and thats the bottom line.

 

All of this "burden of proof" stuff made me giggle a bit. The PL kit seems just fine and doesn't need the entire state of AZ getting their panties in a wad to jump to its defense.

Just to be clear, are all of the AZ supporters group inc (trademark) saying that the waste gate couldn't be placed better? Simple yes or no.

 

We live in the wild wild west. It's hot as F here, our streets are flat and straight and our cars are fast. Many of the guys who have posted from AZ have hands-on involvement with Intense/PL and we all put a lot of pride in our work. It's their prerogative to post here anyways, so what? Is what they're saying inaccurate?

As you can see, I've already answered your question before you ever posed it.

Darren

 

Scott do you know what the build sheet is for the blue G? And what PSI is it running in the dyno posted on this website? http://www.nationalspeedinc.com/proj...-infiniti-g35/ also do you have any videos of the kit yet?
