Apparently the r1 cams are the same as the apex. So does anyone know how you increase the redline and power peak on a turbocharged apex motor ? I want to get the different gesring on the crank to run the engine at 12,000rpm.

are the inner tunnel braces part of the bumper kit or where did you get those?

nice job

I thought you meant for a boosted apex. Do you have any way to monitor knock externally?

Hi Mach eater. Are you advancing timing 6 degrees in high rpm and high boost areas of the map ? After peak torq ?any info you can provide would be helpful. Thankyou

It looks like only the cam cover is mag. @kennyspec & I thought the stator cover could have been mag also, but based on an application of muractic acid, only the cam cover reacted with bubbles.

Muffler setup in place

Some updates... getting there. header primaries half done, thanks to @kennyspec. I couldnt get 1.75 elbows so i went with 1.5. The difference to 1.75 dia is the wall thickness of .065. It looks like the alpine header i had on there was also 1.5. It should spool up quick...

I tried to angle the outlet but i dont think that will help much.. Probably good enough for version 1. Regarding this idle air circuit, I suppose it is run back into the plenum as otherwise there will be an air leak under boost? Could a 1 way check valve be used to stop the boost leak...

Here is my plenum redesign. Due to the fact the apex TB rack doesn't sit centered in the frame, Ive had to offset the inlet to the plenum as can be seen here. (Will add more reinforcement ribs once the final size is determined.) Will this adversely affect uniform flow to each cyl?

yes, I am using PLA plus, an improved PLA, along with reinforncement ribs on the outside of it. 3.2mm walls.

Thanks for the feedback and discussion guys. The intercooler is a front mounted TD cooler, which connectes directly to the front of the plenum. I will be running the TD cooler this year until I make my own. Me and @kennyspec may make a water to air intercooler setup next year, using the...

No criticism taken... It would appear your knowledge is much more vast than mine regarding this. What do you reccomend? Remove them completely? I had been told extending them into the plenum would help alleviate turbulence by keeping them off the back wall, but what do i know? I also noticed...

Added bellmouths to the plenum just a test fit of the printed boots Turbo placement. what do you prefer? With the compressor backwards I was going to route my intake into my cabin, under the hood. With the compressor forwards, I am thinking of adding the nytro oil tank to the front...

Sorry I should have said too big for the stock ecu when using a pcv. Will thr pcv allow empugh fuel to be pulled

I’m guessing these are too big for the stock ecu?

Did you leave the stock map sensor connected ? Surely it must be required to provide proper fueling in vaccum up to 0 vac?

Where did you get thr 1050s I may need these also. How is idle ?

Perhaps a custom 3d printed tank is what you need. I will be running water meth on my swap, Probsbly printing a custom tank to go on the clutch cover where the airbox once was.

deng, already ordered my 90 bends. Will move up to 1.75 inch 0.65. that gives a 1.62 wall.
