I just wanted to do an update on what we finished on the car before the last race we had in homestead this past month. We put alot of work in this car at the last minute to get it finished but it was well work it. here is what we added to the car

Jerico Close ratio 4sp Gearbox
Made Brackets for Jerico Mounting
2004 Mustang Cobra Rear-end with 5.14 final drive
Justin Samberg Cobra Rear-end Cradle
Cut Cradle for exaust clearance
Driveshaft Specialist Aluminum Driveshaft
Cut the Muffler, Gutted and re-packed with stainless Mesh
Fixed Front bumper damage
added return spring to the Throttle
added the traqmate system
added 2 digital cameras with recorders

Big thanks to Big Al for all his help and effort with getting it all done in time.

 

I had to cut up a couple pieces of 1/8 flat steel to make the bracket for the gearbox mount. here is Al welding them up

Then we had to gut almost the whole driver side tunnel to make room for the shifter

here is what it looked like installed

 

Here is the pumpkin with the -8 fittings installed

 

Here is the car all finished. We finished 1st in the race on Sunday. The car which was driven by Al ran awsome and felt like a whole new animal. Because of some issues with the mouts used with the cobra diff. we were un-able to compete for the second race.

As some of you may have seen, we have been hard at work on the second race car. u can check out the progress on the other post. so we have not benn able to asses the damage but im sure we will be just fine for the next even in september.

Laterz@!

wow that thing is a beauty.

 

Thanks! lots of work, and hours into putting this thing together. check out our current project under Big Als race car

 

Stupid question, since you've got a full race transmission, why not use something like a 1:1 top gear and a much taller geared rear end? That way you're not spinning the driveshaft so fast, which helps with durability of the transmission output bearings, the driveshaft will be less likely to have vibration issues, it'll give a stonger R&P (although probably not an issue here), and slightly less drivetrain losses in top gear.

 

the gearbox is geared extremely close o that it never drops under 8000 rpm as long as i shift at 9600 rpm. the reae-end is set up for diff tracks depnding on what top speed i need. Here at out local track, when using the long configuration which involves using nascar turn 3-4 we use the 5.14 rear which gives a top speed of about 150mph. the short cofiguration we use the 6.14 which gives us 130mph. we make this choice based on the fastest straight on the track.

 

Damn Rob, that thing is BEAUTIFUL!!! Seems like there should be an "01" in the side though haha. Best of luck to you guys!

 

We ARE using a 1:1 fourth gear in the tranny. The gearing in just about optimum on this tranny

BigAl...

 

I guess those big tires and higher redline must be the big difference here, since I'm used to hearing about ITS FC's running a ~0.75:1 5th and a 5.12:1 diff with 225/45/15's and having that be too short for some courses.

 

Looks great m8 , what alignment settings do you run?
Have you worked out the rollcenter on the car as it looks low and looking at the front A arm it looks quite angled.

 

Might want to spend some time reading this thread
https://www.rx7club.com/suspension-wheels-tires-brakes-20/howard-colemans-fd-chassis-setup-723617/

Then search on posts made by some of the more experienced people on that thread for more info and perspectives.

 

You might think about seam welding around the trans mounts, they are only spot welded from the factory. The LS1 guys do this to avoid them from ripping out which they will do. Just and FYI.

 

Its been a while since i have been on here but we have been at work on the race cars weather it be my race car or Big Als. Since the last race in December we pulled the motor and gave it to CLR to freshen it up and we have added an additional cooler for the Diff and also changed the way the front oil coolers are mounted. I also added a Racing Brake rear BBK to go along with all the fixins. here are some pics

 

car looks great.........met your brother today, raul....he is rep for Ardex a product that i am using on one of my projects....anyways he said you may be interested in some doors that i have for salvage....send me a pm if you want them.

small world!!!!

 

Omg, how have I never seen this thread! Awesome build up!

 

Rob, what rear brakes were you using before the racing brakes? stock rears?

 

Nice car.

 

can you elaborate some on the relationship between the trans input shaft and the pilot bearing on the motor? Also what throwout bearing are you using?

 

i am using a mazda OEM FB throwout bearing. the imput shaft on the jerico happens to be really close to the mazda OEM size. just need to machine down about .040 if that even. we did have a couple issues with the starter pinion going out enough to catch the flywheel but we took care of that by making a spacer between the counter weight and the flywheel. bringing back the flywheel about an additional .160.

 

Havnt Posted on here in a while so i wanted to throw some pics of the race weekend in April 2009. As of now there have not been any changes except for the Maval Manual Rack we installed prior. I plan on installing the AtomIc Rex rack when the group buy is finised.

 

Great pictures Rob! I'm sure I missed it, but what organization and what class are you running with?

 

We race a local sanctioning body that's only 3 years old www.farausa.com we race mp3. their rules are pretty relaxed (but still pretty fair for everyone), they get a good number of cars at each event. we're hoping to start going to other tracks (sebring, daytona & wpir) soon, its pretty cool to race at homestead miami speedway. the group is definitely growing and each event gets better.

Hmmm, my sister lives in Homestead and I have seen people coming and going from track events all of the time. Maybe next time I visit, I will bring my car.

However, on the site, the link does not work for the schedule. How can someone register without knowing the schedule?
