Fragged clutch is out. Tilton ceramic-metallic 7.25” clutch is in. This rotating assembly about 10.3 lb lighter but the clutch is a similar diameter at 185 mm (?) versus 200 mm for a stock MR2 I think. #racecar #4AGE #toyota

#Gearhead #3dprint of the day is #ITB bellmouths for a #Toyota #4AGE 20V with #isogrid. Modeled in #autodeskfusion360 and printed on a #formlabs form3. The white one is Rigid 10K material. The clearish one is Formlabs high temp V2. I wish the high temp material was more amber, as there's something particularly aesthetic about high temp translucent amber plastics. It whispers aerospace. These will. Be going into an #aw11 #mr2.

It looks like I found a Toyota #4AGE #Formula Atlantic engine for my car. Oddball piston pin size- 19mm. Forged rods and pistons. In a late 7 rib block with deburring, extra oil drains and oversized valves with high lift cams. Needs going through.

So I have settled on a basic #3dprinting based design for #casting a water inlet for a #toyota #4AGE engine with plaster #InvestmentCasting by PLA burnout. I have been frustrated with PVA printing of support so I went old school and sliced the part. I took advantage of the parallel layers and with only minor concessions can generate very good internal geometry. Anticipating the final mass to be 325 grams.
