Sorry I thought you were talking about the guy that started the topic.

 

RT Racing-
Thanks, that's the type of response I was hoping for. It's also pretty confusing because I'm running the 3.5" APS test-pipes and their 3" exhaust and on 100 octane, and at 17psi I'm at 562whp.(I haven't done head work, or changed plenums). Maybe the type of dyno accounts for the 100hp difference? Even if I changed plenums, I'd only expect a 12-20hp bump.

As for Marlucci, I don't know which turbos he's running because the last time I saw his sig, I think it said something about "a bunch of other secret stuff". I'm guessing he has the secondary injectors and/or bigger turbos already. Maybe it's just the water/alcohol/methanol injection?

So, back to the topic at hand, how much power are the APS kits in the crowd making?

 

The RTracing guys setup as far as i know is still high compression. Thats where he's making up a lot of HP.
After seeing and riding in your car Redleader, im not sure there are as many people making big horsepower like they claim. I mean, in your car, you stand on it in 4th I think it was and it would loose traction. So either they are making it at peak rpm and only for a nanosecond or its tuned entirely different then yours because now all i want is about 550, maybe 600 with the stroker but i think 550 is all i need.
Especially those tuned on different dyno's saying dynojet is off or reads higher, I don't understand why people are so naive. Im sure some dynojets might be off but thats a whole nother story.

And Marluci7 has and APS kit with "supposedly" Stock APS Turbos @22psi or something like that.

 

Barthelb-
Good to hear from you. How did he get his boost to 22lbs? I only saw 18psi briefly with the bigger wastegate actuators and springs. And that loudass exhaust of mine definitely isn't a restriction...

You going to have time for the big Z event in Orange at the end of the month?

Maybe you should take your car where Marluci did?????

 

Not sure, I have a research paper due around that time.

I don't know, but the APS Turbos were flow tested and about 18psi is about the max CFM they can supposedly flow. So either a different turbine wheel was used or impeller what ever they are or there is some trick into getting more cfm out of it.
We'll see Jason's car is being built right now and as soon as im done with the Side skirts and rear lip i got i'll have mine put in. Hows your car doing by the way?

 

Or find a marijuana dyno like he did.

 

Boost pressure and CFM are two COMPLETELY different things.

 

So, at a given psi a turbo can flow different amounts of air. Is it not consistent? Dont take this the wrong way i know almost nothing about the technical side of this.

 

Barthelb-
The car is running well. I need to finish it and get ready for summer.
Some ***-clown in a new Z06 was trying to goad me into a race the other day, but I've been a good boy....You know how concerned I am about public safety! (Still waiting for a response on my photo-radar ticket)

1G'- Have any of S.P.'s cars ever run on another dyno to verify those numbers? I know you guys in the Bay Area have your favorites....

 

Latest I heard was 740whp @ 8000rpms

 

True. Two different turbos can flow vastly different amounts of air at the same pressure.

 

I believe they can flow more than that, but anyting after that, the efficiency is going to be shot, and you'll just be blowing superheated air into your engine.

 

From my talks and discussion about he APS TT setup, the turbos should be able to support near 700 whp. IMO, those claiming to be at anything significantly over that are just misleading dyno numbers from an inflated correction factor.

 

CFM is volume of air moved, PSI is the compression factor of said air.

The amount of air that a turbo will flow at a given PSI is determined by the motor's volumetric efficiency. That's one of the reasons why we have guys making vastly different power levels on the same boost pressure in 350Z's. A better breathing motor will allow you to flow a lot more CFM at the same boost pressure.

Make sense?

 

715rwhp @ 8000rpms. Water/Methenol injection, fully built block, 3.5" custom downpipes, 3" custom true dual, plenum, cams, 9.? comp., 22psi.

 

Bruce what shop did the work on your car?

 

First or second time?

 

didn't know there were to shops. I would like to know both and which one worked on it last.

 

Z car garage was the last they fixed a bunch of problems along with the APS oil problem.
