First trip to the track in the DSM

[J_HEATH]

So after building this car with a buddy for a year and a half I was finally able to take it to the track. I went to our local 1/8th mile track in Mobile, AL and with the track conditions (cold weather in the 40's) I was pleased with the results and have faith that the car will get better. Especially considering this was the cars first trip to the track and no real track prepping to the car was done.

I made 8 passes, consistant 7.2@89mph with 1.8 60ft's and one run of a 7.0@89mph with a 1.6 60ft after I hot lapped the car and the tires were able to stay heated up. It was just so cold and having to wait in the stagging lanes the tires stayed hard and wheel spin was constant. Also still working the bugs out on stalling it up and launching. The car was on street tires.

I have nitrous for the car but Im at 98% duty cycle on my injectors so I'm going to have to upgrade my fuel system before I can spray the car.

I have no doubt that the car will be able to run a 10 in the quarter on the buschur 20G. Also it still has full interior. So Im going to go through the car and see where I can shave some weight while still maintaining the interior. The car has only 61K miles on it and the interior is mint. So before I start gutting it out and all (which will probably happen once I go with a bigger setup) I'd like to keep the interior in the car.

Awesome numbers for a economy build man, congrats.

Nice! What kind of boost?

 

[J_HEATH]

28psi throughout all gears. I pulled boost down from 28psi on the launch to 20psi but it didn't help any.

Im thinking with the spray (I have pills for 75, 100, & 150 shot wet kit) I can get the car down to a 10.7 on slicks (26x9.5 hoosier QTP's). The times I ran at the 1/8th mile track were on my street tires and I'm running straight VP Q-16 in the car. In the process of upgrading my fuel system and possibly switching over to E85. $15 a gallon for race gas is getting old.

Nice times. 7.08 is moving pretty quick considering the mods done to your car. You're not far off from getting it into the 10's.

Good job on the car! It is a great feeling to see the car perform after all the hard work.

Nice runs! I don't see what the inj duty cycles have to do with the nitrous though since the extra fuel needed should be coming from the fuel solenoid on the kit. Unless your running a dry shot?

No its a wet kit, I just don't want to take a chance of damaging the motor. Nitrous will increase the boost pressure (spike), so you have to compinsate for that so the car doesn't lean out and go boom.

I figured out what the issue was. I had the base fuel pressure set at 35psi (Manual transmission base pressure) instead of 43psi (automatic trans base pressure)
