Any plans when? Or will you keep your subscribers on the edge of their seat? lol..

What about extended track sessions and heat soak of the air-to-water intercooler? Would a larger heat exchanger help? Is it even an issue?

Also, you should check out GSpeed's track rat development thread. They posted some interesting and concerning information about rear diff temps under track conditions. A diff cooler might not be a bad thing to consider.

I've been following Michele Abbate (SCCA STU racer and 2015 SCCA US Majors Tour Western Conference champion) and a few other Edelbrock SC owners who track their cars and so far the LTR is sufficient given the coolant is mostly distilled water and Amsoil coolant booster. Properly ducting the incoming air straight into and through to the LTR and other heat exchangers is critical as well. Nothing some sheet aluminum and creative cutting with shears can't handle.

I've also seen logs of the intake temps being significantly lower with E85 running on an EForce kit at the track as well. The heat soak will likely become a bigger issue with smaller pulleys than the stock 3.25" pulley that makes ~10psi.

I follow them on here and on Facebook and I'm very confident in my Millers gear oil's ability to put up with temperatures like that, but I do still want that Harrop diff cover to keep more fluid in there and help cool it down.

Removed the stock fuel rail covers



Replaced with Velox units, saving 4 pounds from the top of the engine.








The injectors and HPFP are now exposed and can be easily seen/inspected, which I kinda like.

Any chance you might throw your BRZ on a dynojet dyno before throwing the Edlebrock on? 205whp on a mustang dyno is VERY impressive... But most dyno's that I could compare it to come off of dynojets which read a good but higher... I'm trying to decide between moto-east flex fuel soon or just waiting a year or two and grabbing an Edlebrock kit myself... So I'm looking for every dyno and review, of both, I can get my hands on.

I don't think there's a Dynojet near me.

The physics doesn't make sense; IAT is measured in the manifold, before E85 ever comes into play!

I know, but it's the only log I've seen that's apples to apples.

Added TRD style carbon fiber fender fins

I've been eyeing these too.

Do those replace the fender garnishes or attach on top of them? Seem pretty sturdy after install?

I'd feel tempted to clear tape carbon pieces to keep oxidation at bay for as long as possible

Wow this thing looks like an absolute monster! The mod list looks well-sorted

They attach on top via mounting tape. Yes they've seen triple digit speeds and have stayed secure. They're clear coated finish so hopefully there will be no issues with oxidation.
