964 turbo increasing boost....dyno tests.

[dos531]

Wait so increasing boost without changing anything else isnt a good idea?! Im SHOCKED!!

PS. CIS belongs in the trash can.

I've seen this as very common tuning

Here's my 1992 964 turbo, stock engine with rebuilt WUR and RUF .09 bar wastegate spring. I have not done any dyno work, I feels great!

maybe this WUR was rebuilt to deliver more fuel. If you had an AFR of 12:00, it would drive better and consume less fuel

Despite air blowing onto the intercooler, with a higher boost the intercooler got very hot. Cooled cold water spray was also used for measurements

Sounds a little contradictory to me, so I have to ask do you have a onboard cooled water spray system for your intercooler to simulate the REAL CONDITIONS that you say WE are not simulating in our test.

Richard,

you have to take into account that on this dyno there is no good air flow to the intercooler and another thing is that 4 measurements were made one after the other.

Here is comparison of my car 0.85 bar boost with bigger compressor wheel, sport cat, camshafts and fine tuning on the engine dyno vs oem car with 0.98 bar boost
