The RADX7's First Track Shakedown - Not Quite Porsche Fast...YET!

[@andrzejd5301]

like watching your rebuilds and racing my friend, reminds me of myself back in the day.I've been playing around with Rotarys since the 80s and still love them wish I could go back 40yrs and be 20 again🤣

Why don't you make a radiator shroud

[@markhutchinson3367]

This, also, he needs to get rid of the pressurized radiator cap on the filler neck by the thermostat and put a factory S4 flat cap (no spring) on it. He has two pressurized radiator caps in his system which causes pressure issues, temp spikes and air pockets.

[@bobdavis2807]

but he said that he is going to put e fans on it i am saying put a shroud instead of a e fan not talking about the two radiator caps @@markhutchinson3367

[@Savanna7]

You're definitely on the right track. My FD had to have a baffled oil filler neck (IRP is who I went with) and a baffled pan to get rid of all the slosh. I ended up NOT going with a fully baffled pan, but instead found a drop-in solution similar to the hyromat someone mentioned below. Your time differential also sounds nearly identical to the differential of my well-tracked RX8 and my new Zenos e10R. The Zenos should be ALOT quicker, but I'm still 2-3 seconds off my Rx8 pace. Maybe it just boils down to familiarity in the beginning. (I've also only done 2 shakedowns in the Zenos)

Which OEM proportioning valve is in the car? I remember there were different valves for the FB base drum versus the gsl disc brake setup. Maybe one of the FC valves would work better for your setup before you go the pedal box route. I think the GSL-SE rear rotors were larger than the 4 lug FC rears, but it should be in the ballpark.

[@soloracer1]

Rubber o rings or any kind of o-ring spacer can fix adjuster callor rattle. BTW I never notice a rattle with mine. Springs have wore upper threads down like yours. No worries

[@soarersan1]

Try using an old Nissan patrol master cylinder for brakes. It has a 1"bore which will give better pressure. Cost $150here in Australia.

[@soarersan1]

Try putting louvre panels in the hood. I used louvres from the side of an old room airconditioner. It pulls the air up thru the rad and out thru the hood.

[@mattmartinez3298]

Also recommend making a fan shroud or modify an fc shroud.

[@paulclarkson2583]

Watched you build this beast for ages, damn its good to see it ripping it up. She's rapid

[@Buccafurno]

Need to work on my FC, thanks for the motivation..!!

[@gigglybeast]

Man, this video makes me miss my 1980 RX-7 so much, and I sold it 30 years ago . Subscribed :)

[@ADudesRotary]

Looks like your having a lot of fun testing out the rad7 at the track, racers are always trying new things with their cars, so lots of content to be had with this journey. It is interesting how you compare the handling capabilities of the rx8 to the power of the rx7 and it would be a cool video to rip both of them in a day and hear your thoughts. 😊

[@nater6604]

No fan shroud??? Slam a electric fan on that bad boy

[@guitarzombie988]

I’m not sure if you have said this in a previous video but what body kit is on this car?

[@bobdavis2807]

Why dont u just use Proportioning Valve for brake bias

[@whyshouldipickaname]

He man the rx7 is doing good work! if you will change it over to S-chassis diff it would be awesome, thats what i would like to do.

[@ralphd9753]

Why 8500 rpm shifts? If just a street port, peak power might b @ 7500 or so.. Is it actually pulling hard to 8500?

[@michaellaframboise7646]

Nice to see you again

[@seaturtle828]

An oil pan baffle won't stop the slosh up the filler neck on my now boosted 12a if I only have a baby k and n on the filler neck at autocross I slosh oil out of that

[@jeanfouche6899]

The stock 12A rad is a two row core.

[@pilotohernandez1569]

Use a hydromat strainer with oem tank for hard corners

[@pv4083]

Great job man. I think you reach the point where you should invest in. Driver suit ahha speed is up there on that rx7

[@taol8258]

Looks like a well built track car but please get yourself a HANS.

[@arrivendrive6831]

I really need to know how much power and torque your engine is making. I was always told the rx8 cannot handle too much power or torque

[@RADPotential]

10lbs of boost. Probabaly 330hp maybe 260-270 torque. I'll turn the car up. And see if I can break it

[@arrivendrive6831]

Thank you. I have a Fd and I run about 426rwho and I would love to put a 6sp rx8 trans but everyone in my area said it will break. I have yet to see anyone try to really confirm. For me it is all hearsay. I will be following your car closely. If it holds I am going for it.

[@Sparkling.Fresca]

@@arrivendrive6831 the rx8 trans does not like to be overshifted and banged into gear, it requires smooth and slow shifting, you'd be better off with the rx8 jdm 5 speed, which is just an updated FD trans anyways

[@arrivendrive6831]

My car is not for drag racing but better yet set up for street and road course. You don't really bang into gears on road courses like you do in drag racing. You could do it but not really worth it.

[@bobdavis2807]

Why don't you just buy bc coil overs

[@soloracer1]

Maybe you answered this before. Why move to colder Indiana. If your a indycar car driver I wouldn't ask

[@swampyfox8688]

Letttttttttyyyyyy
