Circle Track Camry

Good Afternoon everyone..  I\'m new to this forum..   I am in the process of preparing to build a circle track Camry racer.

I live in Michigan and the local 3/8mile paved circle track has a new class called \"Pure Stock\" which is V6 FWD automatic tranny only.

Last year a Dodge Intrepid won the points championship..  racing mostly against other Intrepids, a Spirit, a Lumina and a Cutlass Supreme.

I think a Camry would kick some serious tail..  but I\'m new to the car and I\'m hoping the legions of tuners, street racers and drag racing folks here will help me build a great circle track racer.

Anyone interested in giving me a hand ?

If it\'s \"Pure Stock\" how much are you allowed to modify it?

If it\'s really for pure stock cars, the 300M might beat the Intrepids, but I doubt a Camry would. Let\'s be realistic about this - the LH cars were tuned for cornering above ride, and the Camry was tuned for ride above cornering. The Camry is lighter which helps, but the Intrepid was available with a 250 horsepower V6 (as was the 300M). I\'m surprised the Spirit got anywhere, too.

If modifications are allowed, it\'s another story.

Well Dave..  like all things racing, how much modification is allowed is as much you get away with till your caught !!  :-)

The hot Intrepid was a 94 running a 3.3L, as far as I could tell, he had a bone stock engine in there..   nobody is running an 02,03,04 car..  mostly early to mid 90\'s cars..  I\'ll be pushing the envelope in what can be built within budget gunning for a 97/98 Camry or 95 Avalon.

Below is the offical rules..  but I can tell you we also run in the Pony Stock Class (which is a 4 cylinder, FWD-auto, 2V SOHC class) and guys were stiffening frames, putting in lowering shocks/struts, putting in 8 to 10 degrees camber, elevating compression, putting in hot cams, getting heads ported..  

For 07, I know the Intrepid owner upgraded to a 3.5 H.O. vehicle..  which books out at 225hp/215lbs torque and is talking a lot of smack..  and I mean a ton a SMACK.  I want to shut him up in the worst way and with all the knowledge and experience the Toyota community has..  I think we can get it done.

--- full rules ---

Notice # 1: The Pure Stock division is new for the 2006 season. It was added in an attempt to provide a more affordable option to racing. Due to the many makes and models available for use, restrictions and minor changes may need to take place during the season as we learn more about this new division.

Notice #2: Any interpretations of the rules are left to the officials, whose decisions are final. Just because it is not written, does not mean you can do it. The two words to remember in this class are STOCK ONLY. In the event a car is deemed to have illegal parts the car is subject to being banned from all future race events at Spartan and Springport Motor Speedways. The driver is subject to loss of points to date, all prize money for the night and suspension from property.

Notice #3: If you are considering building or purchasing a Pure Stock we highly recommend you receive pre-registration approval prior to doing so. There may be cars that have been permanently suspended Spartan because of rule infractions.

Interesting. I was thinking it was more of a \"run what ya brung\" but this is a serious class - you really have to destroy your vehicle for standard on-road purposes in order to race it. I was thinking it\'d be fun to run the wife\'s 300M but not with those rules! (I have a four-banger myself.) (her car would be illegal anyway - aluminum wheels came from the factory. No steel available.)

Avalon was great for straight-line but the first generation had really sloppy cornering; you\'d have to make a LOT of changes including lowering, better tires (probably half the problem right there), and, well, all the other hcanges you mentioned. Like hiding a strut brace somehow - under the cowl?  Camry was lighter and had a manual transmission with the V6 so you might just have an advantage there. Intrepid only ever had a slushbox so you immediately get a boost in transmission effectiveness. Also that 250 hp engine isn\'t great at low rpm and is connected to a really bad slushbox. Stock though was still 0-60 in about 7.5 seconds in the 300M. Intrepid would be similar, a little slower. If he didn\'t leave it stock he could bring that down a little but not much. Camry V6 with stick isn\'t that far off as I recall.

Is it worth it, though, if you get caught? Those seem like pretty nasty consequences.

You mention slushbox..  remember, we have to run the auto, no manual shifts allowed, however, at race speed locked into first gear, they generally aren\'t too bad.

If we make a motor which turns in the 5800 to 6000 rpm range --- we just run the stock auto in first gear.

That\'s what we do in my Daytona (Last years 4 Cylinder Car) in fact, with that car you can change the transfer gears to get a better gear ratio in first.

We are near 60 heading into the corner..  effective racing range is 4000 to 6000 rpm.

They let us replace the wheels with steel wheels, they don\'t have to be stock for that make, what they mean is we can\'t buy $500 aluminum racing wheels or big offset steel race wheels.

Since we aren\'t turning left and right..  the front swar bar is overrated..  I took the front sway bar off my 4 cylinder and got FASTER..    but a bar in the back is a good idea.

Using a TorqueFlite three-speed automatic is probably ideal for that kind of racing. Agree on the rear bar. Forgot about the automatic bit.  How\'d the Daytona do? It always struck me as a bit heavy for racing; I\'d think an Omni or Reliant would do better. (If you could get the Daytona 2.5 into the Reliant.)

I ran mid-pack all season..  good enough for rookie of the year, not good enough to break the top 10.  I did win 1 feature, but only because the really fast cars crashed out/broke.

the Neon is the dominate car at the track..  i know what your going to say, wait.. that\'s a 4V SOHC car..  yes it is, and I hate it and I fought against it..  but much like how I got the American Made/Foreign Brand\'s approved this year, someone else got the Neon approved 2 years ago.

The track champion 2 years ago had a K-Car with a Mitsubshi 2.6 in it..  that car was fast !   But it had a run in with an immovable object and has since been retired from racing.

We are still going to run the Daytona, your right, it is a bit heavy, the class limit is 2250 and we are at 2400..   but this winter be built up a high compression, N/A, MPI motor and I think I\'m going to take the track at about 180hp which should make me very competitive.

I\'d forgotten the Neon. Even if not for the 132 horses, the cornering would be hard to beat. The 2.6 wasn\'t much faster than the 2.2 but the K-cars were pretty darned light. Frankly with a 2.5 you might be able to get a Reliant up there with the Neons. (Neon took SCCA pretty much the entire time they were made.) The MPI will greatly help. Building it from a turbo, or from a Mexican model, or from an FFV Spirit?

Its a n/a bottom with a g-head and a MPI set up off a turbo.

Hmmmmmm... a full turbo motor has a strengthened bottom end that might have been handy,... still, I suspect the NA is good enough for the power it\'ll be running. I\'d suspect stock, swapping heads and going to MPI would get you to about 120 hp...
