Rob - Any idea on the sound levels you hit on track?

auricomXL 01-15-08 06:16 PM

this project looks absolutely awesome, I've only gone through the first few pages of posts, but i was wondering if you could give me any info on that clutch/brake peddal assembly you have installed? what is that piece of equipment called? who makes it?
thanks.

rob20rx7 01-15-08 06:30 PM

I dont know what the sound levels at the track are. But i can def. tell you that i have gotten no complaints! LOL . as for the pedal assembly, its made by tilton and its an overhand hung assembly for front and rear brakes and also clutch. you can find those at either hrpworld.com or at pegasusracing.com

Hope that helps

Next Phase! (JERICO 4 Speed Trans)
 
2 Attachment(s)
It has become apparent after 2 completed race events that the car needs a good competition Gearbox. I have opted to go with a JERICO 4 speed (Unless a 5 speed shows up) as the gearbox of choice. I will stay with the RX3 Bellhousing as this already has the Mazdaspeed Flyweel and clutch all set up. I have purchased the following adapter that we will begin to work off from. Next i need a Tranny.

Cant wait to see what happens with the new trans. Can you post pictures of the wing attachment to the carbon hatch?
Thanks.

rob20rx7 05-07-08 06:33 AM

Thats still a work in progress now. we have skined the rear hatch so we cant use it as a mounting point anymore. we will have to make brackets that come off the back of the car for the next race and we will be using a diff. wing

This is my next mod as well. Jerico makes a 5spd, but really the 4spd works quite well on PP 13B's. I'd recommend calling Tom @ 7's Only in Buttonwillow, CA - he builds the Mazda GT cars which all use 12A PP motors running the Jerico 4spd. He can probably get you a pretty decent price on it as well.

This was a speacial one i had made. this was made out of Chromoly Tubing so it will be significantly lighter for the Race car

Rob,
what gear ratio you are going to use?
thanks for all the help.
CHE(el amigo de Carlos de Rep.Dom.)

rob20rx7 06-20-08 06:10 PM

i ended up having to go with a 5.14 because there was nothing higher that was closer to 5.40 which is where i needed to be.

jose-rs1 06-23-08 09:24 PM

You can get a 5.125 for your FD. talk to Carlos.
that way you don't have to go to all the trouble of changing everything
unless you are using it because the cobra dif. will make it more reliable.

jose-rs1 06-23-08 09:28 PM

there are also about 200 gear set for that tranny.
so can make any combination you want.
HRP has them.

rob20rx7 06-24-08 12:01 AM

I am aware that there is a 5.11 gear for the fd but it runs almost $900.00 i purchased the cobra rear end for 600 shipped with the axles and the 5.14 gear was 220.00 with the rebuild kit. I will have the complete set up done for less than what an FD gear cost. also i will be determining the final ratio to put in the gearbox this week so i can order the parts and get it together asap for the next race.

Jerico is Apart!

We tore down the gearbox this saturday and i will be deciding on what ratios to run with this week. it was a pretty simple task but i wont know exactly how simple until its all back together.
LOL

you forgot to add the craddle & driveshaft .
but you were going to have to change the FD oem posi anyway and those babies run a lot of dinero. the cobra posi can take much more than the FD.
I have heard about using a Turbo2 posi in the FD. is this true?

Good luck and keep posting

I have the FAL Poly carb rear window on the way and it should be here by mid next week. I should also have the brakes in by Friday.

Nice looking project. How much weight did you save with this hatch?
Thanks,
Ernie
