Not yet, drove it for about 45 mins, ect varied from 81-98c dependin on traffic.

Need to see why that happened. Should be a steady 82-85c.

Also had oil spray on the windshield. Need to find out where it came from

I would say check your oil catch can connections, if you have one.

The internet helps

I routed my breather lines like a wetsump system

Drysump systems dont need to be routed the same way. Rhe scavenger pump is capable of creatin negative pressure in the crank, you just need to create negative pressure in the tank. And thwre is my problem. I am goin to take the source hose off the valley cover and connecr it to the tank. This way my intake manifold creates the vacuum needed in the tank which helps create the vacuum in the tank...

Gettin closer to gettin Smoother afr from idle till 3000rpm.

Found i had an overheat issue, temp ranged from 82-90 on the highway, and 91-98c city driving.

Today i turned the heater on full just incase to release any air pockets that might be stuck. Temps did better, but still needs works.

I then tried to park in a new spot and lost one of my exhaust vacuum actuators.

70$ plus 10 day wait, fun stuff...

Took my girl for a long cruise, temps are better and shows the rad is workin.

The air leak is really bad, i am showin too much positive trim even after i dropped the ifr 5#.

I am goin to use an old treat of pressurisin the intake tube and spray the engine with soapy water to find this leak...

May have found my air leak.

Had my two air connections from oil tank to valve cover was loosely tightened.

A little teflon tape, new orings and plier tight should fix the issue.

But now i have a battery drain that killed my batt in two days. So next check, find the electric bleed and then start and test.

Found the 3.42 helps my rear end grip better from 3000-4000.

Before i was poppin the tires loose, now its much better. Grips, and keeps me planted in my seat.

I need to work more on my tune, i know she has more to give, i am just not tappin into it correctly.

Quick screen shoot of my run today.

Strange enough my commanded air fuel ratio never drop below 14.63 even when I got on it . It just stayed there which is kind of odd...

I made some adjustments, hopefully now it will kick in.

3500-5000 she screams till i change gears, then she screams again till i get to about 170kph, then i have to use the brakes to bring my speed down before the cops catch me...

Today was hot, 50c is what both my cars told me the ambient temp was.

In the shade my v's ect started up at 40c, then quickly escalated to 82c. Normal drivin less than 80mph my ect held steady around 95c. In slow Traffic it spiked to 105c and held there.

I have to see if my 72 pass oil cooler is causin this hot runnin.

I have a 180f stat and all silicone hoses, so i dont know where this heat is comin from.

I have a hd flush in the rad cleanin the coolin system, and 300km left before i change the engine oil out. And i may swap the 50:50 coolant for 40:60 g13 coolant with a new 180 stat.

Could i modify the oem pump to accept the new style stat? Then i can swap in a 174 instead of a 180, with more flow.

Drop down more than that. I just got past this problem. Would spike to 232 here and there running 50:50, 25:75 and it will not go past 205 and it was 102 yesterday. Both in the desert, different rock. Don't underestimate dexcools inability to shed heat.

Dexcool is **** for a number of reasons. You're better off with cheapo green stuff and flush it every year. I use the Prestone premix for "all colors" so far with good results.

Where do you guys get silicone hoses, did you make them or what?
