Evil Street down at Houston Motorsports Park

Guys, just wondering if any of you are interested in coming down to Houston on 9/25 to try your hand in a semi-budget limited heads up class.

We need to get the car count up so we can get the payout up and keep the class going. So far this year the most cars to qualify in any event was 5 even though we had 7 that paid to run but broke before qualifying. Average has been 4-5 cars at each event. Right now there are 3 cars running in the 5.60s, my slow a$$ running in the 5.90s and no one else that consistently shows up. I'm trying to get mine to get into the 5.70s or so and be able to cut a light on those guys that make more power. 2 of the cars in the 5.60s are SBC powered mustangs and one is the SAM car n/a SBF.

The rules are on www.txdrl.com under Evil Street.

* TIRES
o 28X10.5 OR 275/60 Radial max tire size. Smaller tires allowed.
* ENGINE
o 1 carb Ė cast intake, or EFI 1 throttle body cast intake only.

o No coke can solenoids, max NOS solenoid orifice .120

o Any Suspension allowed, front must be bolted in stock location.
o Stock firewall must be in place with only minor modification to trans tunnel for clearance.
o Stock looking appearance: all light fixtures must be in place, but do not have to work. Lexan allowed if you cannot see the frame work holding it in (trim covers rivets). No big wings, no big forward facing scoops (stock style ram air scoop allowed similar to trans am or small boss mustang).
o *QUALIFIED CARS "**MUST BE CAPABLE OF**" RUNNING 6.30 OR FASTER FOR EVIL STREET

Back half cars OK, but donít get mad if everyone bitches that your back half car should be running with the big boys.

Cars must hit the scale and be teched by Evil Street tech prior to first round qualifying. If you win the round and the other driver requests you must hit the scale to prove your weight. Loser not required to scale.

Cars must be driven to the staging lanes, driven from the end of the track back to the pits, and to the scales. Cars must be driven under their own power. No pushing, pulling, or tow/support vehicles allowed. The only time pushing the car is allowed is to advance while in the staging lanes.

If we make 8 cars, I believe $800/300/100/50 or something like that. Entry is $100. If we don't make 8 cars its a 70/30 split and if a sponsor throws in some money, maybe $50 to semis.

Will a turbo 4cly car with a single stage N2O system that uses 4 nozzles be able to run? I'll have to pull the valve cover for you to see the part number on the head and I'd rather not have to do that.

Sorry bud, single power adders only.

Out of curiousity, what does your setup run? What does it weigh?

I have never put it on a scale to see the weight per se but I have corner balanced it. I'll believe that it's about 3100lbs with me in it, a full gas tank, and 2 full 15lbs bottles. The car still has a/c.

It will do 134mph in the 1/4 mile but it is EXTREMELY traction limited because I have always run it on street tires; it did an 11.90 one time but that was with a 2.0 60ft. It will run in the 130s on every pass. Top speed is a gear limited 172mph and it will get there in a hurry.

So you have never put a slick on it or run a low 6 in the 1/8 mile, yet you're interested in running in a class with cars that have gone [email protected] mph in the 1/8?

There is an ET minimum to qualify of a 6.30.

If you're truly interested in running in the class, go to www.voy.com/16243/ for Hotrodgossip2.com and put up a post asking about allowing a 4 cylinder with turbo and nitrous.

I didn't see the 6.3 ET 1/8 mile requirement. I can pull the slicks off of my RX-7 and I'll be good to go for a few passes. 9 bigger pills in the N20 system and some more boost plus a pull or 2 on the dyno to make sure the tune is safe will get me in the ball park. I doubt that I can get it to run a 6.3 ET though. A 6.8 would be closer to what I'd be able to run if I had to guess.

134-135 is all I have run in the 1/4, but recently went a [email protected] in the 1/8 mile. Its all in the sixty foot and first half of the track. I would think a 4 cylinder turbo car would be fairly light in the nose and much easier to hook up than a typical V8 mustang. Maybe you just need a much looser torque converter or to really launch that thing at some real high rpms off a clutch dump.

This race is this weekend and we could sure use some cars in the class. It looks like Joe just made a jet change, small blocks get an 85 jet now, I'm assuming this is for those that were required to run the smaller jets due to ci limit.
