@Abacus Let us know how you think they handle the rain. Do you get a lot of rain at this time of year or is it the summer time?
We get a few showers this time of year. These tires feel as confident as the old ones in the rain.
Ralliart t stat vs stock.
Getting the car ready for winter time. Changed the thermostat from a 76C to 80C.
The Evo has one of the best cooling systems ever made and with the lower temperature thermostat will run at 168-175F at night doing runs. Good thing for keeping temps under control but bad thing for having ample heat !
Going back to the stock thermostat will yield 185-192F . I’ve also got a racefab oil pan that holds ALOT of oil so the oil cooler gets partially blocked off as well. Oil temps follow water temps for the most part so it’s not an issue on this car unless it’s at the road course. These two changes get the oil up to temp twice as fast on the commute to work. Or Mexico.
It’s been a busy month. Celebrated a birthday with a weekend in Atlanta . Spent some time at the wheel of a GT3. It handled and stopped like nothing I’ve ever experienced. Porsche really has it dialed in.
So, when I bought the htz red to upgrade from the hta red years back I opted for the ss housing. I knew it would change the near instant spool up and make a bit more out the top with less back pressure. It still has a purpose and makes power easier once its spooled up.
Most fuel stations have winter blend ethanol that comes in at 72-74 content. I knew we were going to run the car hard so I splashed in five gallons of One Ethanol R fuel. Content went from 74 to 87. Injector duty was near max. Made four runs over 600 before pinning the gate .
675/561 at 43 down to 33psi
655/519 at 35 psi tapering to 32.43
.80 lambda /11.76 AFR ID1700's at 94% at 8100. Walbro 274/450 pump @16 volts. Fuel pressure was solid.
The transient response isn’t near as good as before and it’s 600rpm late to the party to 20psi now in the low gears.I will be going back to the mhi housing and most likely the 4.11 transmission for what I do with the car.
April 2020 update. The covid19 virus has slowed things down and I ended up working remotely for a month. The Evo sat at the shop. It was nice to get some miles in last week. Car is on pump gas when its sitting. Still need to put the MHI housing back on.
Different note, moved out to the country along the river. After mowing the two bumping acres a handful of times with an 18hp 42" residential rider mower I had enough. Two hours and a sore back wasn't going to cut it.
A commercial mower has twice the blade speed,more ground speed and a better cut.
Checked out a bunch of zero turn mowers and decided to go with Ferris. They are the only zero turn with patented full suspension. Ended up with a 800ISX 61" with a Briggs 28hp EFI. Made the first cut yesterday in under an hour while stopping to film and getting used to the mower.
Thanks for making this post Tim. I has helped me make a lot of decisions on what modifications I wanted to perform on my Evo 9.
I am still about response like you are but I am not after a High HP.
Glad to see you are still happy with it over the course of all the iterations.

Thank you. I wanted to keep it simple and anyone can follow the recipe for similar results.
Sidenote , eight years ago today I picked up the Evo. Good times !
I've been an Evo Enthusiast since 2012 and my goal was to build a fun 600whp Evo that could do almost anything and was responsive and reliable . I achieved that goal a few years back. Now, there was another Evo that was well sorted and made over 1000whp at the tire . I heard stories about it back in 2010, then followed it on That Racing Channel for a long time. I told myself that was the one to have if I ever wanted that type of power. Simple, sorted and the transmission will hold the power.
Earlier this year , Javier@TRC (second owner) reached out to me to see if I had any interest in owning a piece of history. I jumped at the chance and after my first ride I was blown away by the performance! The car is on a 245 drag radial and puts down an incredible amount of power without wheelspin or drama. 40-100 feels like a roller coaster.
For those of you that don't know this car , it was built by Machines Gone Wild over ten years ago. Ronnie Crawford built the low compression engine. He looked at the engine before building it for a week. It was his first one and its still going strong even after 20K+ hard miles .
The original owner Richard was a domestic guy that wanted something to go around corners and initially ran the car on the road course. Time went on and it started to make too much power for the road course and it ended up racing elsewhere. He continued to run the car and improve it over a decade. It went from a 35R, to a Super 94 and eventually a Super 99 and a Drenth Sequential transmission.
I was able to catch up on some great stories when I met him including the time he went 184mph in 2007 at a mile event (much less power) and the rear wing folded in half at the top of the pull. The car went 190mph in the half mile in Ocala a few years ago in its current state turned to 11. No tire change, no ice, just turn the boost up and run it. Thank you Richard and everyone involved for planning and building an amazing car. Oh and Thank you Javier!
