A Look at the OTC Racing Engine Build

The Colorado Hill Climb Association was at Monarch Pass July 13th and 14th of 2019, and OTC Racing was there!

Monarch Pass Coolant Drainage system

Installed a new rear exit coolant drain in the race car, unfortunately it let all the coolant out mid qualifying run.  #racecarstuff #morepowermoreproblems #headgaskets #incaseyoudidntgetit still qualified first though.

Original diagnosis was a headgasket failure. But when pulling the heads off to replace the headgaskets, this is what Tasso found

Tore apart about 3 used motors today but found some sweet parts that should save us at least a thousand bucks. So far we’re in $100 on our new race motor! #ballinonabudget #miningforgold #racecar #racemotor #subaru #secondhand

The components of our new motor are starting to look real sexy thanks to Performance Porting LLC. Little by little she’s comin together! #flatironssyndicate #engine #machining #racecar

OTC Injector Inspection

Still don’t have a definitive cause for the last engine failure, but this gunky junk can’t help. Maybe I should do maintenance every once every couple years...

OTC Engine Build 3 - getting back together

Only needed about two and a half helicoils #waitwhat?

OTC Cam Pulley Issue 1  OTC Cam Pulley Issue 2

If you build your #subaru motor with used parts that have been machined, you may end up with misaligned cam pulleys (pics 1 and 2). This is due to the assembled block being a different width since material has been removed, therefore throwing off the timing belt geometry. Eccentric pulleys are available to correct this (pics 3 and 6). These ones are made by LIC and available at Flatirons Tuning. After adjustment the cam pulleys now line up perfectly! (pics 4 and 5)

Wilwood Master Cylinder Installed

Woohoo!  After sorting out the Wilwood Master Cylinder, and the timing components, the engine is back in the car!  #flatironssyndicate

Engine is back in the car

If you listen to the Flatirons Syndicate Motorsport Podcast (why aren’t you listening?!) then you know I’ve been saying that I’m gonna make a megaphone exhaust. I wasn’t kidding. Also I finally cut out the dumb smashed section of downpipe. Next step: start motor.  #flatironssyndicate #exhausted #racecar #subaru #dunebuggystuff

Old Exhaust  Trumpet Exhaust 

Ya it has a cat, who’s asking?! #becauseracecar or uuhhh #becausestreetcar or whatever #becausebangbang

OTC Race Cat

The exhaust was sitting outside while the motor was out being built, so some squirrels used it as food storage. This is only about a quarter of the stash. Sorry, squirrel dude, hope your winter works out.  #squirrelsquad #prepper

Squirrel Stash

It’s supposed to finally get above freezing tomorrow and we’re hoping to finally start this new motor. I’ve been worried about excessive wear and poor lubrication in those crucial first few minutes. Turns out Flatirons Tuning carries the #subaru block heater kits and they’re super cheap and easy to install. I might just leave it on for all the cold weather ethanol goodness. #formula1 preheats their cars so... #racecarstuff

Getting the old girl stripped down before she heads off to see @wrxbuddy at #unomeracing for that new hotboi livery. #naked #stilldirty #staytuned #flatironssyndicate #myfingershurt

OTC without decals

Dude Motul USA killing it again with the product design details. Also, for consideration, where the 300v smells like a fruity cocktail, the break in oil smells like science. #themoreyouknow #flatironssyndicate Check out the Flatirons Syndicate Podcast with special guest Matt from Motul USA!
