So this turbo has been taking a"pounding" for over 8 pages now, and this whole time the chart has not been SAE corrected for a 50 degree F temperature difference?

Wow.

 

That's pretty much the long and the short of it, Robert.

Seems that some vendors on here either have an interest in seeing certain products fail or they just don't plain have the knowledge of where to pickup rpm on a car that he claims to be an "expert" tuner in and doesn't know or care what SAE correction is there for.

Regards,

 

so what should the numbers be if someone were to correct them ??

 

Even with SAE, STD or whatever and Zero temps I don’t see this turbo making the 400+WHP with no cams!!

This turbo does loose power and torque in the lower end and gains a bit on top end.

Honestly I don’t see it doing much better than stock turbo.

That’s only my opinion.

Thanks

 

I don't know about expert tuner, heck hes only been doing it for what 2 years. You do have a good point, every dyno graph he posts with NO rpm points. I wonder why that is.

 

couple horses more maybe none. No one really knows until you see it. You can download the software (WinPep7) from dynojet.com and test it with some raw files.

Usually the STD factor reads ~8WHP or more around the 330WHP than the SAE.

Uncorrected reads the highest by far but I am not sure why they are saying it matters (as it will read higher).

Maybe there is a part that I am missing but I really don’t have the time to test the software now

In booth cases it won’t make that 40WHP that everyone is looking for.

 

if it will make 400 whp with race gas and suporting mods then I think it is an option vs the tme

 

What you have to consider as well is that the tune wasn't altered at all from the BB TME to the WR...or at least that wasn't mentioned. Only boost levels were changed with no ignition or fuel remapping.

Would it make a difference? I say stay tuned for other flash tuners to start tweaking these things.

 

SAE correction depends on if you are above or below 72 degree F. If you are above 72F then SAE corrects the power up since there is a disadvantge of hot air. If you are below 72F then SAE corrects the number down. 37F, if it was really that cold that day, is really going to correct down lower than the actual power. 85F will only correct up by about 5whp or so.

 

Totally wrong.

SAE correction can show either higher or lower than the raw data. Humidity has a very minor effect on the result, ambient pressure has a noticable effect, and ambient temperature has a HUGE effect on the results. Standard temp for SAE is 25 deg C (77 deg F). If conditions in the dyno room are substantially higher than 77F then the SAE corrected dyno chart will have substantially higher power readings, if the conditions on the dyno are much cooler than 77F then the SAE corrected chart will be substantially lower than the raw data chart. Taking an uncorrected chart from one turbo dynoed in cool spring weather, and then comparing it to an uncorrected dyno chart from a new turbo durring a heat wave in the middle of summer will prove absolutly nothing.

my car was tuned at 111 deg !!!

 

Incorrect.

 

Very Good post... was beatin' to it.

 

Judgng by ambient conditions noted earlier in this thread, I'm guessing the WR would see an SAE correction of 1.04-1.05 while the TME turbo would see a correction around 0.96-0.97. I wonder who is going to get the "pounding" now

shiv

 

Well, all this is very nice... Dynos here and there... How about feedbacks from people with the WR on their car!!!!!!!!!!!!

Here is my feedbacks:
Replaced my TME turbo with the WR. Tuned at the track (MSR with AEM)...

2nd run, went 1.2sec faster than my best time with the TME...

Ask me if I like my new turbo... I like, it's just plain bad ***
