TurboOutlaw, sure it was just a double post but we got that Don't let the locals ruffle the feathers, we just get used to how things usually are sometimes. I want to personally thank you for sharing the info, since I didnt spend much time on the straight pumpgas part of the tune when I did my most recent test. Also since we have just 92 here it was nice to see some 93 numbers.

Thanks

Aaron

 

and your point is?

 

i didnt know i had to have proper grammar to talk on an internet forum

thanks for pointing that out

your post was off topic btw

 

Proper grammar is good if you want anyone to believe what you say. We can be friends. I'm not here to be a dick.

I'm just saying. To figure out when a turbo spools, you need to datalog. You can't go off of feel or off of looking at a boost gauge and your tach. When you come in saying "boost turbo 3900 red me car" (exaggeration ) it just seems like you have no idea what you are talking about, even if it is true.

To make worth of your argument we need proof to believe its validity or put enough trust in you that we believe you have validated it.

 

You can't say it "I hit 25psi @ so and so RPM on the way to 29psi"

The car will spool quicker the higher the target boost. If you set the car to hit target 25psi, usually it will hit 25psi later in the rpm then if you where targeting 29psi.

take your peak target boost, see what rpm it hits that, that is when your car hits max boost.

pretty simple concept really.

There is no way the black hits target boost at 3900 rpm in 3rd gear on the evo 8/9. Red's barely do that on the evo 10 and they spool faster than 8/9.

Either way, congrats on the power OP.

But you have to ask yourself, what would the red of made with 6 to 8 psi more?

Scorke

 

Sorry, kept that to myself haha. 30psi., so figure properly then 4200-4400 for a black, figuring cam variations into play and such??

 

You're right it was 4144rpm . Some of your statement depends on boost control system and wastegate I believe.

 

I wonder why would GST and John Bradley argue about something that they both know well by more than 99.9%?!?!?!?!

Both of you ARE professionally knowlegible and I think that you are common, tuning-wise!!!

 

Not arguing to be clear. I respect Bryan more than most people on this board, I feel this is just ribbing on a professional level. I am trying to determine if its how the dyno loads the car that makes the difference or boost control method.

I posted a log that showed my target boost with a slight overshot so I have direct evidence to support my claim. I also have comparable logs (from an RPM start point) that show on the Black with a 22psi actuator and AEM EBC that reasonable boost levels spool about the same rpm. I had originally said 3900 which appears from logs to be more in line with the Red. The Black is a little over 200 rpm later at 4144rpm (according to the log posted) and when started at a higher rpm on the dyno (3500-3600) its around 4500 but the transient time from 14-30psi is the same in both runs.

cliffs- I am not arguing with Bryan Differing in opinion based on our Dynojet only.

 

Here is the latest with the FP Black: Added Aquamist & 26-27 PSI - Tuned by "Big AL" of Dynoflash. Run on Pruven Performance's dyno (same as last time).



Time for a clutch...

 

^^ those numbers seem really low on a DJ..

 

Look's very low for 27-28 psi and Alc !!!!

 

2nd that. Thats like power youd expect to see a Red make

Afterthought: Granted of course, thats wayyyyy below the boost the Black should be run at. Hell, thats even way below the boost a Red should be seeing. So its not surprising. Id like to see this set up at just around 35-37psi.
