Trust me that is a mini-post for Gurgen probally took him 10 mins max... Check out some of his other posts

I am sure he will chime in again soon

None the less I think you have and awesome kit Tim with some great potential, can't wait to see whats next, Congrats on the awesome power!

Good luck!

Thanks George. It is definitely not going to put out the power it would with a GTM stroker and our torque is no where near what you guys have made with that big *** motor but hopefully soon we will see what it can do on a stoker motor and even then we will still not make those huge torque numbers

 

why does this happen to every thread made about dyno results, geesh.

congrats turbotim on a job well done.

 

Let me know if you/any of your customers need one

I know.It is funny.In the GTM thread there are guys pushing for the SAE charts because they feel that is the industry standard and in this post others want the STD results because they feel as though those are the industry standard From my own experience it seems as though most people accept the SAE numbers in the Honda,Mazda,Evo,Porsche,BMW,Toyota,etc....forums as the industry standard so that is what we like to use.Either way does not matter to me because we will just continue to pursue our quest to the 1000WHP mark!

 

I was thinking the same thing, lol

In the end its just numbers and no doubt that car will scare the pants off of some people.

 

Good point......I have noticed that dynos are not nearly as scrutinized on the Porsche forums. I'm just learning about all this correction stuff and I'm sure there is an implied level of knowledge in this forum section.

 

People on porsche forums genrally are not magazine racers so they dont fight over dyno numbers with ricer math.

 

Just to further validate your point, my turbos arent even upgraded, they are regular 18G.

 

That's what I was hinting at, but ended up being thrown under the rails too. Oh well. Too much debate and not enough focus on what's been accomplished.

In any case, congrats on yet another milestone. The kit has insane potential.

 

To satisfy everyone.I will be posting the charts with the STD correction.It dropped the chart down by 8 horsepower on this run I guess the next thing peopel will want to see is the chart with no correction at all

 

Are those our 60-1's on that kit Tim?

 

With SAE correction my car would make MORE power at elevation. Want to try and dispute that?

Don't get your panties in such a bunch. I complimented you..and this is the response I get.

The FACT is the car didn't make 640rwhp...it's power level was CORRECTED to 640rwhp using a standard correction factor which doesn't work with turbo cars at elevation because they create their own "atomsphere". Yes it has a little less oxygen than normal, but the NA correction factor should NOT be used on a turbo car.

 

STD corrected dyno chart:

 

Yes they are Ed. 60-1 Hifis IIRC with Stage 3 turbines and a .63 A/R

 

So what correction should be used then? The car did make this power or at least really close to this power and there is no disputing it. I already broke everyhting down and like I said orignally,You dont think a pair of 60-1 hi-fis with a built motor, with a point more of compression, can make an extra 60WHP over Phunks set-up? He certainly thinks its possible. George at GTM did not dispute it and neither did Shariff so who are you to dispute these charts that were done at an unbiased shop, who SFR has no association with or have ever even heard before this was done.

I posted up an SAE corrected chart and now I just posted an STD corrected chart. So which one is right according to you? None of these are acceptable because there should be no correction for turbo cars at a mile high elevation, right Bri? That is BS! The fact is that I dont want to get into it but now you are saying these charts are bogus and that is pissing me off.I dont think you dont know enough about turbocharging to tell me what is real and what is not and how a larger turbo that moves more CFM per psi of boost wont make more power then a smaller turbo that moves less CFM per psi of boost.Because ultimately,that is what you are insinuating.Take care.

 

Regardless of numbers, the striking thing about his dyno chart...that many people overlooked....is that they are finally making power convincingly to 7000rpm. This is a sign of turbocharger that is making good airflow, with plenty in reserve, and some good tuning. Even when we tune the Greddy with race fuel, and race mapped ignition timing, power drops off at 6500rpm or so.

The slower spool, and shifted trq curve, is also a sign that these big turbochargers ahave re plenty of room to stretch. I really like the chart.

Todd did some high elevation and low elevation dyno tuning a while back. Maybe he can shed some light on how his numbers compared between sea level and 5000ft.

Tim, can you send us some manifolds so we can play too?

 

nice numbers.

 

You need more then some manifolds if you dont want to dick around and fabricate a bunch of stuff but you know we are here for you Sharif
