well its one thing i have to admit you have learned.. and its when to quit

 

Yes, I know you'll sit in front of the PC talking in circles all night. No use in trying to outdo you or you'll pull out your adult diapers and go without sleep just to respond.

 

Keep the thread OT guys

 

more? if you say so....

 

Will you guys just stop the bullsh!t and just admit that the stillen sc is the only way to go for big power.

 

Damn another fight.

Doug never shuts the *** up
Taurran thinks he's god
We have a mod askin for more.

WTF is going on???

 

I think by OT, ZUL8R meant ON topic, not OFF topic

So you made this power on a stock TN kit, stock waste gate, on pump gas?

Sorry, but I don't really believe it, are you sure you weren't running that 75 shot of nitrous you stated in a previous thread?

Having done what you claim, I don't see it being possible on what you have said. Unless your tuner ran a ridiculous amount of timing for this "1" dyno pull then severely backed it down afterwards.

But hey, I could be wrong, please don't take any offense, just don't want to beat around the bush!

Nice car and build regardless, hope you enjoy it - I mean that.

correct, this thread is about ABL 2 FLY's car, not anyone else's.

 

help me understand something...............how is it that most of every car on here that are making high numbers are only able to run about 15psi of boost on pump gas give or take a 1 psi or so......but after that they're running a race gas mix w/pump gas, straight race gas, or meth to be able to run higher boost without detonation...............how are they able to pull 19.5 psi on just 93 octane?.........anyone cuz i need some K-nowledge

 

most high numbers you see are the TT kits, they are making over 500whp on less boost.....remember "power not psi"

 

Because you don't fully understand how boost works. Different turbos operating at the same boost pressure are not equal in efficiency, meaning they don't flow the same amount of air/exhaust.

 

Good #'s I'm going to try to push my TN kit past 400 this fall. Why so many haters on here you must have made some people jealous. Have fun with the car and try and keep it in one piece.

 

George, no problem and no offense taken at all. These numbers weren't posted up to brag. They were just posted for information. Both the HP numbers and the car specs are accurate, but take them for what you will. That being said though, 535WHP at 19psi and 93 octane doesn't seem that unreasonable considering you guys made 527WHP at 17psi and a 91/100 octane mix with the same kit. We're talking a difference of 8WHP. That's only about 1.5%.

Either way, we've never met so I understand the skepticism. My sons and I have been building 350Z's for about three years now (Sharif has helped us with a couple of them) and have been through a number of supercharger and turbocharger configurations (and unforunately engines too). We're working on a 4.2 liter stroker now that we're thinking will make about 1000WHP. The car is being built as a road coarse car (HP will be turned down a bit for the track) and is scheduled to head up to VIR at the end of the year. You can see the curent specs here: http://www.nationalspeedinc.com/cars.php?id=7&offset=0

I'll post up the numbers and track times when we get done.

I'm looking forward to seeing results of your new project. I'm very interested in seeing what those GTK turbochargers will make on your setup. The factory ratings would tell me they'd be capable of around 900whp, but it could very well be more or less depending on other factors. Good luck!

 

We decided not to go with the GTK's, and are currently working with Borg-Warner to develop a different solution.

 

well the huge difference is the change in wastegate.. thats what brings skepticism... The wastegate that comes with the TN Kit has been known not to hold boost very well after 15 PSI.. most of the work done by other tuners after 15 PSI the boost will drop off drastically.. making little power up top.

 

Tapering boost would be related to backpressure and piping, not necessarily the wastegate itself. Wastegates regulate boost, so there's really no "limit" to what boost pressure they can hold, but are limited by the amount they can flow, which in turn causes backpressure.

The only way a different (larger) wastegate should help is if it's installed with an open dump, allowing backpressure to be alleviated by releasing a larger volume of exhaust gasses when it is open, bypassing the restrictive piping entirely.

Look at the dyno sheet. Boost is tapering off almost 2psi as it stands, and he's making peak tq/hp by only 5500rpms. After that boost tapers off over 2psi. I don't see what's so hard to believe.

IMO, in this case and others, the control allowed by the standalone engine management system is what's allowing the tuner to push it past 500whp. It's all in the tune.

 

nice, they make nice turbos, a friend of mine is going with those turbos as well.

 

I wish dynos would log air intake temperatures along with boost. Then we could "see" overall kit efficiency right on the graph and take that out of the guessing game.

OP, did you happen to catch what the Haltech was reading for ATS?

 

Sharif's dyno does. I got some graphs of AIT vs HP on my blower.
