the highest pressure valve is 55-60psi, meaning it will not discharge until pressure drops below 60psi. Since the target oil pressure is 125psi above 5k rpm, and the powerband is from 5k rpm to 9k rpm, we want the unit to discharge any time the pressure falls below 125psi. Yet, we dont want it to have to fall to 60psi before it discharges. Therefore, I cannot see how an EPC will pose any significant benefit

 

Finally all finished up with suspension and brakes. Brakes all bled and done this weekend and all preliminary ride height baseline adjustments set on the coilovers. First touch down off the jack stands in a few month

Now its time for corner-weight and alignment, finishing the accusump plumbing to the engine, and fire suppression system. Can't wait to get back on the road and do hot boi **** soon enough!

 

The louder the better,

Looks like Road Atl has no noise ordinance, they are gonna wish they did after this aha

 

Ear bleeder.
Your gonna need a back-up plan.

 

custom molded light delete inlets with connections on backside to the tubing, flush with bumper now

 

Looks like were going to have to postpone the track stuff just a little while longer. Strapped the car to the dyno to check the tune one last time before planning to hit Barber for the first time yesterday. Driving around off boost everything was fine. In boost the was making an easy 700 at 12psi. However, I noticed what appeared to be a light mist of fuel on the rear motor mount near the exhaust manifold. We wiped everything down, and took another run, with eyes on the intake / exhaust. On that second run the exhaust manifold burst into flames on the rear runners. Thankfully my friends put the fire out while i was still in the car tuning

From day 1 the intake manifold flanges have misaligned with the peripheral port flanges and always a pita to install. Most likely, the intake manifold was not placed in a jig when originally fabricated. The vanjen style clamps, typically allow for a decent range of misalignment and flex, but in this case it's a bit too far past the range. I replaced the o rings and it put back together and noticed the same misting of fuel. This has been something that's been occurring anytime the car has been in sustained boost over the past years I just never noticed the fuel before it evaporated. Luckily I have not driven the car hard, and thank god, it decided to catch fire and shout out to me now on the dyno, and not a day later at Barber or on the street under boost where lives would be at risk.

This goes to show that you can never be to sure, you can never rush things, and you must always check everyone's work. Do not blindly trust anyone.

The car will still be at Import Alliance this weekend. It doesnt leak or have any issues under vaccuum/idling. But we dont want to risk driving it until the manifold is chopped and rewelded with correct angles.

Thanks to all you guys who follow and keep me motivated. This isnt a set back, it's a silver lining ! So thankful to have the chance to notice this and fix this! The universe works in interesting ways.

Luckily we have competent fabricators here that can fix this issue for good. But I cannot stress enough, how it can all go down the drain, including your life, down to one simple fabrication error. Always be prepared.

Its a blessing, this is the absolute last piece remaining from this fabricator on the car. Once this is sorted there's no more hold ups in sight! Can't wait to get to the finish line

 

Since there's nothing else to do at the immediate moment thanks to PPRE again lol, might as well install a make shift F1 tail light

 

Wow. Good think you had watchful eyes. Had this burned down we would have been inundated with rotary flame/reliability memes (and of course you would have lost an awesome car).

 

Hard to get a clear shot of the signals that doesnt blow out the camera because they are so bright

 

Which LED bar are you using?

 

I definitely dig the ducts.

 

Great weekend at IA

Now just waiting to get the car back to fabrication to fix the intake alignment and its game on!

 

Game on!!

How much does she weigh? Do you have any official curb weight?

I would just guess around 2400lbs

 

Looking forward to the updates - Have you figured which fire suppression setup you're going with? Novec 1230 seems to be the best suppression agent from the few articles I've read on the subject,

 

Wouldn't the misaligned runner thats causing the fuel leak also cause a vacum leak which would create fictitious map readings and in turn cause tuning issues? Man, how did you get this far with tuning with a vacum leak?

 

what kind of alignment specs are you running?

 

possibly, but probably doubtful, there's alot more absolute pressure generated with boost then the minimal vacuum the pport pulls. Will definitely be interesting to see what happens when the clamps get fixed beginning of next month!

 

2800ish give or take fuel / driver

 

haven't locked down a specific alignment yet, for initial testing, around -3.5* camber front, -2.5* rear camber, 0 toe front, -1* toe rear, caster where ever it falls in the front and as even/as much as possible

 

not yet, hopefully soon! Kinda on hold for a bit until fabrication date comes up at end of the month to fix the intake leak!

 

Awesome time bringing the rx7 out to barber this weekend for the Indy races. It amazing how much the sound of this car moves people. Brings great joy to see the same excitement / feeling felt in the crowd. The sound just never gets old! Dare say I was a bit saddened by the Indy engine tones. One day we will get this thing properly screaming around the track. Bring back Formula 1 v8s and v10!

I foolishly drove the car to Barber's from the shop. Pretty risky knowing there's a potential for leak under boost, so I stayed off the deep throttle. So tempting lol. She did great. 175F water / 175 oil, and 105F intake temps, the entire ride. A little low speed 15mph traffic or so, and 85F weather. Rock solid.

 

Rotary goals! Your build is beyond awesome man! Glad you caught what could've been catastrophic!

 

Finally getting around to fixing the last of PPRE's fuckups. Stripped the runners and hammered the **** out of it to try to straighten it out. Before and after posted above. It was off center laterally and gapped. Now its centered with only a slight gap. According to the manufacture of the clamps it should handle up to 1/4" of gap. But who the **** knows what to believe anymore lol. Going to pressure test the manifold with inlet cap and turbine cap, and smoke/air pressure tester while using 0.1mm oversized o rings. If it still leaks, then its time to cut the flange off, build a fixture, and weld a new one thats dimensionally perfect. Fabb'd and welded a bracket to the front of the intake to keep it from moving around/lifting under boost/load changes. Seems like such a simple thing that could have been done by the original creator.

Hopefully ready to get back on the dyno soon and thrash the tires



Got bored so decided to corner balance the car. Got it from initial 40% cross weight up to 50 with 220lbs placed in driver seat. Can't complain.

 

I wouldn't complain at all!! Those numbers look awesome!! Very nice!!

 

Haha Awesome!! You were pretty spot on with your guess!
Those are still really good & balanced numbers despite how much you've done to the car.

Its gotta be an amazing feeling, finally getting to the point you have gotten to.
Looking forward to more YouTube videos of it hopefully on a track someday.
