I'll also probably convert to manual brakes. Let me knwo how it performs,

Riz.

 

yeah because there hasn't ever been a car in the world without power brakes...... sorry to inform you but there was a time when cars didn't have powerbrakes... also without the booster you should get better feel from the brakes..... but hey, i'll find out who is right or wrong soon enough

 

a general rule of thumb is every hundred pounds lost is a tenth of a second gained...just tearing out your rear carpet is a retard way of looking like a race car....but when you go to the extent that my car has gone there is a very noticeable difference in performance

i'm sure i have lost a few hundred pounds.... ( sunroof and sound deadening alone is about 75 lbs.... not to mention everything lost from hvac, all the stuff in the engine bay, etc...)

im not sure exactly what i've lost yet but when i get the coilovers tuned in i'll get a new weight for the car and now how much weight was shed

going tonight to pick up some lexan to replace the side windows and rear hatch....more weight shed

MUUUUUAHAHAHAHAHAAHAAAAA

 

it's just too difficult to build this rx7....

i'm starting over with something a little more my speed






holy ****!!!!!! there more parts in the model than there are in the real car!!!!!!!!

i'll stick with the real 7

 

I am looking foreward to seeing this evolve.

Keep the updates and sarcasm coming.

What kind of facility provides lexan? And can I get the dimensions? Also, will the side windows still be able to roll down when they are plexi-glass?

 

fortunately you can glue these together though.

mine unfinished
crappy cell pics

 

dude i have that same model kit!

 

You even riced out the interior with red shifter/radio/gauge surround.

 

all i can say is.....SKULL SHIFTER IN A MODEL CAR!?!?!?!??!??!!!!! F'ING AWESOME!!!!!!


didn't do much work on the "Junkyard Racer" lastnight.....just finished pulling everything off the firewall (pedals, insulation) and stared at it A LOT





hopefully by weekends end this thing will be ready for paint.... on the inside anyway

 

Hey now, don't get nasty...
I am well aware that cars didn't always have power assisted brakes... they are old. And also they didn't weigh very much. The 2nd generation has power assisted brakes. Hmm... I wonder why Mazda put them in there...
This is a safety issue. Best of luck to you when you really really need to stop. Good luck in court!

 

Quite the opposite...older cars tend to weigh a lot more than new ones.
They also had worse brakes and smaller tires.

I depowered the brakes in my 240Z and really liked the feel.
Been considering it for the RX but haven't made the plunge yet.

If I did, at the very least I'd change the pedal ratio...something the OP ought to consider.

 

try grabbing a book and reading up on braking systems before you start to make assumptions.... it is not a safety issue, it was added for comfort and ease on the driver..... the brake booster has nothing to actually do with the movement of the fluid through the break lines and to the calipers from the master cylinder, it simply uses the vacuum from the engine along with some springs to make it easier to push the pedal in.......

i "get nasty" for this exact reason.... people want to talk trash and try to belittle other's for doing something different when they infact have no idea what they are talking about..................

 

CLOKKER!!!!!! THANK YOU for actually having said something knowledgeable

way ahead of you on the pedal ratio... thanks

 

I'd love to see how you do that.
It doesn't appear possible to move the MC up very far given the constraints of the stock firewall hole but maybe it doesn't take much?

Also, I'm wondering how the activating rod is kept centered on the MC piston bore or if that's even a concern.

Any info appreciated.

 

ok bare with me on this one.... i measured the ratio to be about 4.333:1 on the pedal which is actually pretty sensitive for manual brakes (manual brakes are usually around 5:1 to 7:1) so i am actually gonna bring the pivot point up about 1/2 in which should bring it to about 5.2:1....

the pedal assembly is spaced from the firewall exactly 1in. so to keep everything solid i'm gonna just cut some spacers for the 2 mounting points on the MC...



there is PLENTY of room on the pedal to drill the new hole for the pivot point....



the rod is not an issue, i actually busted the booster to pieces and salvaged the rod that was connected to the pedal, i had to grind some ribs off of it, but the ball on the end fits perfectly in MC and the length seems to be right ( i will see when it's all bolted in)... the diameter of the MC is much much smaller than the booster so all i have done is made a center line between the 4 original bolt holes on the firewall and moved it up a 1/2 in. from that line, the huge hole in the center has plenty of room for the MC to move








this is my "GRAND PLAN" but we will see what happens...also there is plenty of length in the brake lines so other then some bending no changes will be needed to get the lines to fit back in (thank god)

 

It's not a safety issue. In fact power brakes would be alot harder to control (looking for correct English word... not found) and might be more dangerous without ABS.

It's just for lazy people who are spoiled with all kinds of gizmo's and asists in their cars, cause they don't want to actualy DRIVE the car.

This is looking quite interesting, cant wait to see more progress, and some final weight #'s

 

most places that deal in windows for homes and buildings have it.... home depot or lowes might even have it.... remember that lexan is a brand name... you are looking for polycarbonate sheets... its not very expensive at all to purchase, and most places will cut it to the dimensions you request.... if you have a JAY-K lumber around you, thats where i got mine....

as for rolling it up or down yes that is not an issue, you can mount it just like the stock window... to save weight i am pulling out my motors and using a seatbelt strap with buttons.... a button at the bottom of the door for open and one at the top of the door for closed.... google it because it's pretty common in drag cars and things.... also some of the more race inspired muscle cars had the set up i am doing straight from the factory (just a little tid bit for ya so i dont have to hear the haters tell me what an idiot i am for using a seat belt strap )

 

That car has easily shed 200-300lbs of crap weight (when you include the single exhaust/header/etc)

 

Screw the haters, please add a link or pics, cause I have a hard time visualising this. Might be because English isn't my native language, or just because you're not being very clear. LoL!
