Guys, please read the dyno sheets correctly if you are going to be so critical about them.


Tobz mustang is 1.2 CF so this car really makes 302.5whp/356wtq

 

holy crap! i can understand changing it alittle due to the elevation, but not that much.

 

lol.. Its fun to play with it and wack off in Virtual Dyno but not on a pro dyno.

 

Correction was 1.19.
It is a sniffer so leaner by a point in the tailpipe.
There is nothing to worry about
The x turbos at this elevation fall off really bad....because of that they make a great tq spike and fall drastically. That is why the HP is not as high as you wanted.

 

Most CO dynos use a weather station which change the CF from about 1.16-2.24 so it's not TOBZ, it's just the weather station. Other dynos here are a set 1.15, regardless, it's just a tool.

 

Im aware of the weather station, but i believe they have it locked in at a static CF for this dyno. correct me if im wrong tobz.

 

No the number changes it does not stay at one number. I have tuned many cars on his dyno and I know it does sway.

Well based on the CF then I'd say the engine isn't necessarily in any unsafe zone considering real wtq is far below 400 which is considered the safe limit for the stock rods. I wouldn't run 31psi through a stock turbo if you paid me though...that's just pushing hot air and is the only reason the tq spiked so high also it can't be good for the turbo. Most people run 26-28psi on stock turbo after being tuned and you can still make great power at 26psi if it's setup right, EX:my sig @ 26psi with a stock downpipe

 

but this is really high elevation, so your 26psi wont be as powerful where he lives. you cant forget about that.

 

thanks for clearing that up Mitch.

 

Well this is true however it doesn't negate the fact that you shouldn't be spinning the stock turbo to 31psi...it's WAY out of its efficiency range and wasn't designed to be run at that psi.

 

Can you show me a compressor map for the Evo 10 stock turbo? If you could factor in each 1,000 ft in elevation that would be great too.
