i want i want so bad.

 

amazing.

 

This car def has its reputation, and is one of my favorite Evo's by far.

 

keep up the good work guys,the beast is looking promissing for 8's. merry xmas and happy new years to all u guys and shawna of course lol, ill be up in a few weeks after i put the 35r on my evo so we can re-tune.-k.adams

 

looking good stm crew, hopefully you guys break into the 8's in 2011

 

always loved those te37's on that car

 

Em,
Maybe another reason you haven't addressed or thought of in regards to the increase in crankcase pressure is the dynamic seals on the turbocharger. Given you're running t3 housing... your pressure ratio (exhaust pressure/boost pressure) will be very high.... 1.5:1->2:1. Given Precision's and Garrett's lackluster design for sealing the turbine housing from the shaft and therefore oil drain... you end up with a lot of pressure in your crankcase coming from your turbine housing... thus why you need more ventilation.

Take a look at the new BW turbochargers if you get a chance... their new EFR turbo's trump the PTE/GT's CHRA design.

 

You know I was seeing issues with my FP black where the oil would shoot up the return line and leak out of the center housing rotating assembly and drop oil on my starter.

Since then I drilled out opening on valve cover, so we will see if that fixes it.. but i read on Google on multiple forums that its a common thing that occurs on Garrett turbos in general.

I thought it was the turbo, because ive never experienced that before.. but if it stops happening after this mod i did i guess thats my answer.

have you ever had this happen to you before?

 

hi
did you just make the 2 valve cover holes bigger any pic etc pm me if you like

as for stm car iv see alot of your vids on youtube some car

 

tscomp,
your seal on your compressor side may have failed... the oil coming out the compressor seal is usually from cold starting the engine and revving it. (high oil pressure... overcomes the seal and pushes oil) This is also due to an insufficient seal design. We've fought this problem for a few years now. Solution is... get your oil pressure under control and use a better CHRA design.

 

Thanks Ernie. I know there are plenty of places that can cause crank case pressure. I'm sure the turbo is some of the reason but even with Boost leak tests going over 50 psi we can not here the oil bubbling so I cant see that being the big issue. As far as these new turbos go, I will let you guys run and test them. If you run fast and the keep together it could easily be something in our future but for now I will stick with what I know works in this car. Shawna's car on the other hand may test some other parts soon.

well thats not good....... fp told me its normal for the seal to leak that its not supposed to fully seal?

My rom makes my car idle around 2k on initial startup and oil pressure is 100psi+.

When I was having this issue it was about 50F outside.

 

read this entire thread it has good info + pics and other stuff.

interested to see what she tests on her car next.

 

Right on Emery! Haha. Stick with running what we've all proven and what's being written on forums. The turbine wheel in your turbo along with the turbine housing is keeping back pressure down on your car as it is. We've done a lot of back pressure testing with FP and even driving the hell out of a 35r turbine wheel the back pressure stayed in acceptable levels.
