The bigger valve will definitely make it louder.

We have found in the last 4 months, that the compressor and the throttle is heavily loaded.
The problem is that at high engine speeds and throttle closed, much air needs to be transported away! Over the Bypass.
The "25mm" Turbosmart BOV comes here to its limits.

With the Stroker- kit (4:07 liters) and the compression ratio of 10.5 : 1,
needs the engine more air than before.

Using the same compressor setup I had before the engine conversion 10 - 11 psi Boost.
Now only max 9 Psi! The amount of air from the Vortech is the same.

With the new conversion I want to achieve about 12 psi boost.

The following parts and adjustments are made in the next 2 weeks:

- All bearings and seals in the Vortech V-3 Sci be changed
- New Vortech Pulleys (High Traction)
- New flat belt (compressor and engine)
- Converted to Speed Density
- EcuTek optimization
- Full Service (oils etc.)

With the Speed Density conversion I can intercooling evaluate after the plenum cooler and set the new water pump on the best regulation.

I will report as soon as the "Z" is with me ...

(Hope you understand my bad english )

Hey there, I just bought a Stillen supercharged 40th anniversary Z about 5 months ago.... haven't been doing anything close to the awesome stuff you have done to your car, only silly things like short shifters and led lights.... I did get it uprev tuned for altitude, hopped up to 410whp at the last second on a dynojet. Just wanted to say thanks for the great thread you have kept going.

Next on my list is an oil cooler after having read through all these pages, either that or selling it because I'm afraid I am going to blow the motor! What do you think caused your piston burn up craziness??? Low oil pressure from adding an oil cooler... son of a!

I am thinking of going with a Z1 motorsports 34 row kit

https://www.z1motorsports.com/z1-pro...it-p-4135.html

any thoughts or suggestions?

Hey Guys

A dream come true for me!

(The Problem with the 370Z Engine..... )

But this year it is 100% work!

At the start in SCC500, Rolling50

From 50 km / h speed start ..... and then one kilometer full throttle ....

I can now no longer be asleep

Swiss. That is why I switched the 25mm bpv out with a vortech 50mm or Tial 50mm bypass valve.

A guy from the 350z forum hit me up asking if ill make a kit for the stillen 350z's. He said he went with 2 high gpm pumps and a large trunk mounted water reservoir and its not working very well.

The trick for you Swiss is to get more efficiency out of that supercharger. You will always be battling heat and if you are going to try for 12 psi it is going to get much worse.

If you are going to be putting in fresh bearings and seals you HAVE to spring for the Si upgrade. You will get 2 more psi out of it and it will still be more efficient.

So what impeller is this? Are you supposed to gain psi from it and if so how much?

Nice!

You should tell the person with the GTR swap to join the forum and share their story and build.
