just posting some results with my mods. i hadnt been to the track in almost a year so i was really itching to go. i didnt really change anything since the las time so i wasnt expecting any better times than before. i started out with a 12.4@ 115. i had a good launch with a 60' that was around 2 flat. i went right back in the staging lanes and waited a good 45 minutes because the place was packed. it was getting later at night and was starting to cool down. probably 65 degrees out. i did a little burn out to clean off the tires and started to stage. got my best 60' yet of 1.94 and ran the quarter in 12.2 @ 117.6 (new best MPH) with that MPH i was getting psyched for the next run, hoping to break my 12.1 but i ended up breaking something else. my next run started off good, but as soon as i hit second gear something didnt feel right. the engine felt choppy, like a missfire. i took it easy by not banging the gears as hard and ran a 14.0 @ 101. the car definitely has a misfire now and feels like its only one cylinder thats bad. i am hoping that its just a plug or something easy. i dont think its anything internal yet because its not blowing smoke or making any funny noises such as clanking or clicking.


summary:

12.4@ 115
12.2@ 117.5
14.0@ 101 with a missfire now

mods:

procharger @ 8 lbs, 3 core intercooler, 42lb svo injectors, bbk headers, bbk throttle body, borla catback, delteq, obd I conversion, bmr torque arm

 

sounds good im hoping for a 13.00 tonight on 3-4lbs and street tires might wanna check your o2 sensors i had one go bad on me and it made a poping misfire sound just my 2 cents whats the regulations on needinga roll cage? you sound like you are getting close

 

i am pretty sure the roll cage requirements are for 11.49 and quicker. i WAS getting close, now im far away

 

Hopefully its something simple and not a broken ring land or burnt valve. Good times.

 

well i would think a broken ring land would have more symptoms than running choppy

 

>actually it's 11.99 or quicker (13.99 or quicker convertible)

the track i go to follows IHRA rules

 

>you didn't say that
good times ... hope it something minor.

 

Nice! I think might be bad though... broken ringland could definitely be possible.

 

well im in the same boat too........ just limped the car back home from the track aparently when you launch on ET streets the stock torque arm wont hold up LOL!!! ripped the top portion off where it bolts to the top of the rear end (moser 12 bolt with 4.11s)

anyways back to you ummm so when you gonna trouble shoot this beast? im really trying to learn as much as i possible can about forced induction even the blow ups helps to give me reality

 

so far i have just checked to make sure all the spark plug wires were still on. this weekend i will be pulling the plugs and seeing how they look. if they look fine i will be doing a compression test. it should be interesting to see how i am going to be getting the compression tester hooked up to some of the cylinders, such as #7. the header tube curles right around it. its hard enough just getting the boot on the plug!

 

i hear that im running AS&M mid lengths and on the passenger side OMG its a pain when i put the turbo on i blew out the passenger side primary gasket then a few weeks later the drivers side so THEN i orderd stage 8 bolts and put them on the drivers side and im pretty sure the passengers side wont get them till the motor comes out
