Kevins wastegates really rock....

 

Odd statement considering my positive results and the fact that Tial does work for EVO on the various Garrett turbos. They also manufacture some of the best wastegates around.

FWIW they were an easy bolt in for me. Maybe you are confused with another "tail" company.

Look at how flat the boost log is when using these springs. This is from my 993tt with K24 hybrids (not Kevins) and greddy EBC

 

WOW, cool plot - I love that sort of detail!
Question:
1 How did you get that plot?
2 Why does the MAF voltage max out even as you keep accelerating and using more air? If the MAF is undersized, you must revert to the stored ECU values for timing and injector pulse width based on RPM and Load correct? Would it not be better to get a larger MAF that reads your airflow accurately up to the max, for more adjustability? Perhaps WOT doesn't require a lot of 'tweeking' to get maximum safe power?

 

Greg the owner of TIAL made this kit for the KKK turbos. It includes billet clamps and special springs. He would not sell something that does not work. I use them with very positive results.

 

No they have a different accuator assembly they use with the garrett cartridge kit. Its not a modified KKK one.

 

Thats pretty funny. I should have seen that one coming.

 

I'd like to get info on a group buy!

 

I have both.. a tial 44 mm on gt 35r garrett ball bearing turbo( evo8).. as well as Kevins billet wastegate on my stage 5 zero clearance(TT)... both are great and do the job. Huge difference in spool up and sustained boost.. doesnt drop off like the stock wastegate under full load.

 

Mark,

What are you replacing your stage 5 turbos with? With all of the success of the garretts I have to guess thats your plan. If so you will not be disapointed.

Tom

 

Yes Im going to a set of gt35rs and 44 mm wastegates with .8 bar springs.... all custom piping I/cs.... headers, exhaust.. etc.. and much more....
I must really say that Kevins stage 5 zero clearance turbos are the ****....I had k24s race FVD turbos and they were a dog.... too much lag... i didnt hit full boost til top of the 3rd or 4rth gear... stage 5s are awesome... simply no lag... seriously.... it was the best set up I had without having to get into the engine and or add injectors/fuel pumps.

 

Sounds like you have a monster plannned. I have seen SCARGO install many such setups. You will not be disappointed!!! Sounds like you are doing the external wastegates. Very good move. I have only seen one set of custom IC's for the 996. It is on Chads car. I must say they are impressive. This is an area often overlooked. When will it be done? Which injectors are you going to use? I can recommend some.

Those FVD turbos sound pretty sad. Here is a 1-3 gear log of my home brew K24 hybrids. I hit full boost in first gear with my 993tt.

 

Wow so much information, must do more research haha!

 

thas exactly how Kevins stage 5 act... full boost 1st gear... i freaked out...
and the stiffer spring turns this into a whole different car.

 

here is a pic of my new I/Cs

 

Wow Mark nice!! Damm i want Kevin's turbos badly, Mark lemme know
