Did you delete the AC?

I sure did.

I looked at today’s pics and saw all of that clean real estate where the compressor used to be, lol.

Yep, deleting the A/C compressor, condenser and plumbing, vacuum pots for the IMRC, and the active shutter box opened up a lot of room. I'm all set to add boost, but wish I had thought about replacing the harmonic balancer with the FluiDampr, but I'll do that when I add boost.

Yeah, you’re all set to have some fun NA for a little while before adding boost.

I like the Fuidampr because it doesn’t have to be rebuilt. I’ll be putting one on mine. I couldn’t imagine having to rebuild the harmonic balancer every race season like some brands call for. I like the idea of one and done much better.

Yep, I'm interested to gauge the differences between NA now and NA a few months ago.

For boost, I'm seriously considering ESS. Been watching them for a while and I like the simplicity of it and less heat soak.

Chad. Very. Angry.
The video doesn't do the first fire up justice. The bark literally shook the back wall.

After leak check and rolling around underneath on the creeper, all was good. The front end went back on, front tires installed and torqued, fired it back up to idle and come up to temp. Then, it was road test time.

I don't know how much each individual heat management item contributed, but all-in-all, I'm highly pleased with the results. With a CHT of 183* (coolant temp about eight degrees lower), ambient at 60*, the IAT toggled back and forth between two and three degrees above ambient. I'll also add that my belief that the coolant pump impeller is undersized for this engine for performance applications has been validated by what I'm seeing. Comparing the Coyote coolant pump impeller to the GT500 impeller reveals quite a difference. Even with the 170* thermostat and stock coolant pump, I wasn't seeing CHTs this low. Also, evacuating heat and making the baffling that isolates intake air from engine bay heat seemed to do the trick. Could be there's also something to the heat shield on the bottom of the intake.

After five or so miles of shakedown, punching it is quite different than a month ago. It breaks loose at 50 mph, front end jumps, an he gawn....

A little bit left to tidy up on the baffling, tighten up one wiring harness and run about a 1/4 tank of 93 out, then it's fill up with E85 and squirt the tune in.

Awesome job! Glad everything turned out just the way you had planned for it to. Enjoy that newfound sound, power and cooler IATs.

Thanks, Dude....it worked out well and it's definitely a different NA car....and getting closer to boost. I'm waffling between the ESS and a PD system.

My next steps are to prep the fuel system. I'm highly intrigued with what you've been doing and have been studying what @engineermike has shared. I'll have a full tank of E85 by Saturday and will datalog after a few miles on E85.

Right on! Can’t beat that E85, especially given all of the effort you’ve put into keeping things cooler on the IATs. You’ll not only have the clean and cool burn from it, but the bump in power too.

Yep, pretty anxious to see how much more this car evolves once it's on E85. Also, I forgot to mention above, the spherical bearings in the tension links really enhanced the preciseness of the steering, but I'm sure the K-Member is likely contributing to that feel as well.

Did you install the spherical bearings in the rear too? Great mod btw.

Not yet. I'll be tackling brakes (GT350R Kit), wheels and tires next, and owing to the policy we share, the new knuckles in the rear will get sphericals pressed in. It is said though, that sphericals are better for drag applications and not road course, so I'm looking into the validity of that. Maybe @K4fxd can weigh in on this....

I've got poly or delrin in the rear suspension. I like the bearings in the front.

If it was race car only, or mostly, I'd have bearings and rod ends everywhere

That's good enough for me, sphericals in the rear it is. Thanks, Dude.

I can say that adding them in the front added another level of precision in the steering.

I thought the front crash bars were aluminum ?

Weeeeelllllll mine definitely aluminum.
