Sorry, I don't, but you can get the dry sump cover and related parts (ie regulator, p/u tubes etc...) at mazdamotorsports.com. just browse the race section of their catalog and you'll see everything you need with part numbers.

You boys need some serious therapy. I am in the midst of my own project car (nothing like yours or Robs, except for maybe the ITBs) so I know how much this stuff costs. Looks like you are having fun.

Rob actually calls it a disease and rather than therapy we wants a vaccine administered intravenously.

Both Rob and I have been pretty busy lately but we have tried our best to get some work done. Below you'll see we are now finished with the bumper/fenders and the radiator. The oil coolers came in so we've started mocking those up.


Here is one last pic showing the brackets we made for the fenders

Here you see the brackets we made, we welded solid round stock to the bottom of the rad and used some old radiator bushings from by buddies evo 8 then fabbed up these brackets, you can see a piece of the card board we used to mock up the brackets.

This is the front bracket, it's uses a cotter pin to lock down the radiator, with no hoses or water I can remove the rad in less than a second. I'm ready for those radiator removal races!

I decided to go with this type of cooler over the conventional setrab or mocal for a couple of reasons first they hold 1.6 quarts of oil each and second it's pretty obvious from the seperation of the tubes they flow more air, plus they look pretty awsome.


Here is the first step to installing them.

We should have the coolers installed this week!

Very nice stuff, I am guessing the Dzeus fastners are for speedy bumper removal also?

We want to run the car as low as possible but the problem with running low is you can't get it on the trailer without destroying the bumper so we made the bumper quick release.

I see wouldn't it have been much easier to fab some ramps or something? Are most of your track shorter tracks, I don't know how pronounced the added drag would be from increasing the frontal area with that bumper (not all that important on a short track).

Please don't see my comments as criticism I wish I could do something like this just curious.

Fantastic looking Al! Thanks for the referral on the Jerico too

I really want to front-half my car the way you have too; amazing how much more room there is when you get rid of all the stock crap.

Thumbs up Quick Release Bumper

It was the expireince with my car that led us to going to a quick release bumber set-up. My car is low as it is and would have been nicer to go a little lower but for the bumper there is just no way as mentioned above. I already have 7.2" foot ramps and i still have to jack up the truck significantly when we have to load the race car. We figured since we already had to cut off the front end of the "Majua Pingua" (second race car) we minus will just go the route that will make most sence in the long run. we do have maybe an extra 15-20 hours of work x2 but well worth the end result.

no offense taken, I see Rob covered the ramp question. As far as using a bigger than stock bumper the issue really isn't aerodynamics, it's cooling, you're really able to maximize your airflow with these after market bumpers. I'm of the opinion that the added cooling is worth the added drag. Also we plan on making a scoop to exhaust the air coming through the radiator out the top of the hood, that should be worth some down force.

Sorry I just reread your post, when you talk about increasing the frontal area are you talking about this picture?

if so the bumper is not actually wider, it's the fiberglass fender that's actually bowing inwards, which is why we made the brackets to push out the fenders. Normally the fenders would just bolt to the bumper and the bumper would hold them out where they needed to be, but since we made the bumper quick release we needed something to hold the fenders.

It's been a while since I've posted, I went on a little vacation with the family. But Rob and I were back at it this weekend, we finished installing the oil coolers and already made one of the shrouds, we also started the headers. The headers are almost finished, they're all tacked, just need to finish welding all the runners. I'll be posting pics on Tuesday.

As promised here are the pictures of the headers, It took Rob, Ray and I all day Saturday to finish mocking these things up, and then another evening for me to finish welding them up but we're very happy with the results. All three runners are near perfect length only the middle rotor is off by a 1/4 of an inch (good enough for carpentry work ).

I actually picked up the phone with the intentions of ordering inconel, but then I asked for the price and those intentions were quickly forgotten!!

We got started on the exhaust today.

Some of you might wonder how you get the exhaust out, here ya go. We bored the holes and then inserted a 5inch piece of tubing and welded in place, just to keep some of the integrity.
