Hello,
I have been tuning this car at the shop and trying to get some bugs sorted out and finally got everything worked out.
Now this car was acting strange from the get go. The car started life with the twin scroll HTA86 with a .78 on the backside. The car would spool stupid fast but after 18-19psi the car would get way backed up and you can see it in the curve as it would start to U.
So after talking with ETS we went with just a single scroll .82 T3. The spool is slower for sure but it woke way up in terms of power!!
Now I ran into another problem that I would like to share with the rest of the community as I don’t know if anyone else has run into it.
I could do pulls when the car is cold and it would pull fine and make pretty solid power, around 390 on 22psi. But once the car started to get hot it would fall on its face. I boost leaked checked, ran over everything and I just could not figure out what was going on.
When I was doing pulls it would feel like the power band was “light”. It just felt like a misfire but it didn’t really sound like it. So to just to test my paranoia I put the stock coils and the stock plugs in and bam! The car went from falling on its face at 360 to 454 in just one pull!
I didn’t run a test to determine if it was the plugs or the coils but my guess is the coils. They acted like the dwell was too long and heat was saturating the coils. Sometime in the future I want to put them on the O scope and measure it but that is for another day.
This is back to back between the Okada coils and the stock EVO X coils.
Anyways here is the mod list:
EVO X GSR
Stock Block
DW 1000cc Inj
91 pump fuel
ETS HTA86 Turbo Kit
Cobb AP
FMIC
Custom Intake and UICP
Kelford Cams-Stage 1
This is really high for our dyno. Normally Evo X’s with 35r’s do around 420hp-430 max. This HTA really screams!
Thanks for reading,
