Ended up dynoing the car yesterday in this Texas heat
Got some heat soak but here are initial numbers with the stage 1 tune alone

Sam has been guiding me along the way, and has even offered to help with data logs even though I did not buy the Cobb from him. He has been a real joy to deal with.

 

Good numbers. Get the upgraded Intercoolers to stop the heat soak.

 

Cheers Nab!

Here for whatever you need. Now you have a good base to refer to as you go up the crack pipe ladder

Let me know how either of those exhaust options pan out. That will open her up!

 

What was the baseline?

 

being the genius I am, i failed to take the cobb to stage 0 in order to get a baseline run.

 

Curious, where in TX did you dyno? I have some customers in TX that are looking for a local dyno but it seems there aren't that many around.

 

I have been to Cobb in Plano and I know they have a dyno there.

 

I went to eurocharged in Houston TX

 

Shouldn't these cars make more than 48x whp stock? What am I missing here? I was told around 500 stock for a 991 Turbo S? Am i wrong?

 

Every dyno reads differently and numbers are based on a lot of factors.

 

Not surprised. 40-50 wheel hp is typical for just a tune. For big power you need to remove the restrictive stock cats and get high flow cars or catless. And more Even more you need to upgrade the puny stock intercoolers

the tuners can only turn up the wick so much before the concern of high exhaust gas temps frying the stock cats come into play.

 

Maybe Im just reading this graph wrong. What is this car making?

 

Best run shows 483 wheel hp on Dynojet which is 579 hp at the crank assuming a 20 percent drivetrain loss. The gain from stock to tune only is not great on the 991'Turbo. Car really needs high flow cats or no cats to allow the tuner to unlock the power

 

480-soemthing is even on the higher side of what we usually see from these cars in stock form.

Normally, we see something in the 460's, maybe low 470's. However there are some cars that are just stronger than others for whatever reason.

 

This car was dynoed with the cobb stage 1 off the shelf tune and made about 485WHP and 600 WTQ

HP number was a bit low, but I didn't expect much HP gains without supporting modifications, I was told to expect torque gain, and with 20% loss 600WTQ is about 720 crank torque, which is a gain of over 150 from stock if you factor in the overboost
