Retro Racing R build

[biknman]

Retro just needs a better builder, like the guys who run in the BTCC!

However they did order up 12 engines.....



They use a wet sump + Accusump, or atleast they did in 2016. I don't know what they have for the 2018 season:

But keep in mind the BTCC cars don't pull the Gs our 818Rs can. They weigh 2800lbs and run on 10" wide wheels. Also the downforce is a lot less than Retro has going.

I saw somewhere on the interwebs they also come up with s clever pickup in the pan the swivels:

This is the situation Mountune faced when developing the Subaru FA20 engine for use in the British Touring Car Championship where the rules required retaining the factory wet sump.
Goodwood 3814
To give the best chance of being able to provide a high pressure supply of oil, a clever moving pickup is used. This swings inside the sump in response to the lateral and longitudinal g forces the car is being subjected to, meaning that it essentially follows the oil around the sump

Sorry everyone, been a busy few months. We had to complete the KMiata, had a few stupid things happen with it at the enduro (oil filter gasket and trans input shaft bearing failure) that cost us the race, but the engine was perfect. Now, we need to get it back in, pull the trans, fix the clutch......in Feb....maybe.
That said, we decided to replace ALL the wiring in the 818, install a wireless steering wheel button setup (https://www.pegasusautoracing.com/do...ocID=TECH00124) along with a ton of other bits, while waiting to finish the engine wiring. We hoped to complete it by mid December, before pulling in our two RX7's for SCCA E Production prep, but failed miserably so won't get back on it until mid Jan.
It's really hard to start and stop, just want to get it on the dyno and tuned!!!! Will try to stay on updates, sorry again for the delay, building and repairing 5 cars after work and on weekends is draining.....

did just get a new stacker trailer though!

when is the dyno session?

So, finally an update!
Based upon Gator's transmission post, we decided to rip it all apart, modify the frame and transmission mount, raise the front of the engine and lower the transmission to level. It turns out, this was the BEST option that we should have done from the beginning! The engine would have ended up fitting with a baffled oil pan had we not decided already to go down the drysump route, but there you go...
This engine would fit even with the gas tank in the stock location, with an oil pan btw. 4P racing is building these engines to 400hp N/A! We, however, decided to make the VF23 turbo fit, setting it to 8-10psi to get there on a stock engine.
Start up in the next week or so, then over to the dyno. Going to scale it soon after, but we think we will be about the same weight. No body mods so far, just some frame work and extra stiffeners. Thank you again Gator for catching our mistake prior to us burning up a trans!

Look who's back! Hopefully this summer we'll have your 818, Dragonfly's, maybe Tony's former 818, and mine racing in Conference at the same time!
Fuel Safe is designing a 16-18 gallon fuel cell for me that will fit in the stock location and fill on the passenger side. That should be enough to get thru our 1 hour mini enduros without a fill, and when we do fill I feel a LOT safer having the re-fuel happening on the other side of the car.

Keep your updates coming!
