IM using a Cosmo pump from SR Motorsports. Didn't help, my car cutout with 1/4 tank of gas at the track.
Like the previous post stated, just changing the pump wont help.
The reason I changed mine was due to the mods I have. I didn't want to run into fuel starvation problems due to low flow rate.
If you bump your H.P. up the stock pump could be a weak link.
Mazda designed the fuel & cooling systems close to the max. When you change things you find out how inadequate they are for moded cars.

Fuel Pump
 

I will be upgrading my pump for the 2002 racing season. I have not had a problem with starvation however I do like the idea of added safety.

I anticipate I will need a pump that sits farther down into the gas tank or make something. My concern is fuel starvation.

I have noticed starvation in autocross with less than 3/4 tank. At thunderhill I was down to 1/4 and it was ok. However in autocrossing it starves much easier due to the sharper corners.

Thanks for your response. I was hoping you new of a pump that reached down further into the tank. I will check out the cosmo pump prior to purchasing anything.

Thanks

Spank

Fuel Level
 

Would love to see you race with 1/6th tank of gas. Unless you have done the fuel line mod you will be sucking wind because you cannot get any fuel. Unless of course you are slower than granny then your fuel level will be fine.

Re: fuel starving
 

Remember what Chadwick said, if you are running that amount of fuel and are not starving, I hope you are one of the guys that are in my class.:)

Your statement tells us how fast you are going!:o:

Don't get pissed, just pointing out a fact!

As far as the starvation goes, lower the pickup if you can(whether you get a new pump or not).

As far as AutoX setups go, I've been doing some research myself.

First of all, forget about Super Stock, unless you're out there just to have fun because there's now way you can seriously compete against a 405HP Z06 vette.

Second, decide how much money you want to spend. To be in a competetive class and not blow a whole lot of money, ASP is your place. But that means there's a whole lot of things you can't mess with. The biggest one you can't mess with is BOOST!!! I've gotten some suggestions from AutoXers that won nationals in a FD. Shocks, go with double adjustable konis(from tripoint I think). Tripoint makes the sway bars of choice as well. I forget what the choice is for ASP but call them and they'll tell you. Exhaust, forget those fancy catback systems, 3" straight is the way to go. Breaths the best, weighs the least, and it even sounds good. I got mine done for $150 and it was worth every cent. Hoosiers are great, but super expensive. Kumhos are a whole lot cheaper but not as sticky. 17" rims are probably the way to go to keep things light. And don't forget the alignment!!!

For some more money, and the ability to mess with all the boost you want, the new SM2 is your place. In street mod, you can do almost anything. You can even throw in a 3 rotor I think(any motor that was made from the same manufacturer). Stick with a sequential turbo setup. Single turbo will kill you in AutoX.

SM2 is where I'm planning on going eventually but I'm going to work my way up. See you at the track.

It is hard to say what mods you need to make the FD a beast auto-xer. There are so many posers out there modding the hell out of the cars and still getting beat by Neons, average drivers in Neons.

If you have any sort of budget, stay with stock wheels with R-compound tires. Hoosiers seem to be the fastest, but Kuhmo V700s aren't far behind, they last longer and cost about 40% less. This combo is really more than just about anyone can handle. If your losing by .2 sec then the Hoosiers will give you the edge. If your losing by 2 sec, then you need to learn to drive.

The FD is really a monster on the course in stock form. Of course we all know the C5 Vette (Z06 and std version) are faster. The C5 knocked the FD out of the trophies nationally before the Z06 came out. So besides the fact that you won't beat a good C5 driver I'd suggest ASP. Do the bolt on mods, play with setup ALOT. I ran my car in SS for two years, switched to ASP. It took me 3 alignments to get my setup to work better than stock (with custom alignment).

Bigger brakes are a waste of $$.

Removing pass seat? Dumb idea.

PFC= prepared class
Street port= prepared class
3mm seals, we all know you don't need them to run lots of boost. Running lots of boost= Prepared again...

Running with a little gas, bad idea as others have mentioned.

I think setup and driver skill is far more important than anything. Of course after you do it for a while you'll find that your 10mo old tires don't stick like new ones either:).

oh yeah, agree with Jeff. Forget about big brakes, they're not important in AutoX. Spend your money somewhere else. Also, don't go buying any crazy racing brake pads. They take too long to warm up and they're hard to modulate. I've been told, Hawk pads work the best. I have a set I just bought from RX7Store(thanks Jason), he has the best price I could find.

ASP & Boost
 

You can run an upgraded ECU with the Fuel Cut removed and still be legal in ASP. Rule states that you cannot manipulate the boost.

I have called and it was confirmed that upgraded ECU is fine for ASP.

So what freakn class would i run in? I've got every single bolt on, BNR stage 3 turbos, street port Power FC, 17psi of boost, making about 500Bhp, front anti sway bar, tower strut brace, toe links, trailing arms, koni yellows, eibach springs.

Any ideas? I havent got into Auto cross cause I figured I'd be playing with some hardcore race cars.

I was doing a search for some info...sorry for bringing this back from the dead. By the time I got to the end of the post I forgot it was old haha

STEPHEN

Still relevent though. Better a continuation of a single thread then a billion threads of the same subject with one or two responses.;)

run in street modified 2. your car is legal there and it should be the most competitive class that it is legal in.

What Class to run in?
 

As stated either SM2, AP or BP. Run in whichever class you feel you have the best chance to win in of the above choices.

I currently run in SM2.

Love to see ya running in one of the National Events.

read this, know it. mod according to which class you want to race in. learn to drive. stock wheels with sticky tires. and for those of you who say rx7's aren't competetive against z06's, a local rx7 recently finished second in his class against 3 vettes. 2 being z06's and the 3rd a redular c5. oh, and learn to drive. wow, i too just realized this is an old thread. noise falling on deaf ears i suppose.

Don't put too much worth on regional results. Nationals is the true measure of what cars dominate a class. SS is a lost cause. No way a legal SS RX-7 will be competitive at Nationals .... I even doubt it at Divisionals. ASP is sort of a dying class; but one could be competitive there. Again though, more Z06's will start sorting out in ASP this year ... tough competition. SM2 is really the only place left to go. And it gets expensive in a hurry. I'm almost setup for SM2 and so far, appear to be competitive. We'll see at the National Tour. ;)

So what. Like redrotor pointed out Nationals is what counts. I beat guys locally in Vipers and Z06's all the time; doesn't mean my car is better.

That's why the winners win.

Given equal talent under the helmet a Z06 is a better car for autox. Why RX-7 drivers take this personally I don't know, but thems the facts.

Damon, you won't have Donovan to kick around in SS this year at the Tour. He and Amita decided to stick with the E36 and stay safely tucked away in BS. Hopefully, DFL is not in the plan for you this year. I'll be rootin' for ya. :D

it just seems that people make it out to be a lost cause, and if this guy is asking what a good setup is, he probably won't be going to nationals (no offense). good point though.

Who actually made it down to SD for nationals? I think I saw Spank in his Black SM2 but I didn't get a chance to talk to him since he was in the middle of fixing something in the back of his car.

Well crap. He failed to mention that to me :o: We had a friendly rivalry going at the Divisionals and Tours. I guess this means I automatically win by default :D Does that make Amita tire warmer or is she staying in BSL?

I think you mean the National Tour Event in San Diego? Typically when you hear "nationals" used in speaking of Solo we all assume the winner take all national championship in Topeka every year.

BSL. Man, ouch buddy .... you and 9 other Z06's. Chris Ramey is registered in a C4 ... I know that's a typo. So, make it 10; half of which I know are fairly to very good drivers. Then again, I'm chasing 2 turbo Miatas. Hehe, should be a fun weekend. :)

I figure I am either fairly good or fairly bad. Depends on your point of view I guess :p:

To run in SuperStock, Best is Porterfield brakepads, Tri-point 10way front sway bar, Either GAB super-r or Koni DOUBLE adjustable dampers, and Stock wheels with Kumho. Of course, we talkin bout R1 or R2 right?

2 neg on front with 1/32 toe out and bout 1.8 on rear with 1/32 toe in. Then again, it's all up to driver's preference eh? i prefer ladies who can swing that ass
