well i went yesterday to the burnout contest in fowlerville, made a little smoke but my engine got hot and burnt three spark plugs up! has anyone ever done this without a blower or nitrous?
were you pinging at all? It should have been hard on your engine, but it shouldnt have burned up unless you were pinging I dont think. I have done similar things, but never in a large group or even legally.
Too much air , not enough fuel AND/OR wrong heat range on the plugs are usually the culprits. Seeing as your running a naturally aspirated setup I'd guess your running the stock heat range on the plugs, which should be OK. So I'll start with the questions now......
1. What mods have you done to this motor, if any?
2. Have you checked your fuel pressure recently?
3. How old (in miles) are the plugs?
4. Are all 4 plugs in the picture above from the same bank?
5. What kind of shape are your o2 sensors in?
The plug I'd be most worried about is the first one on the left....Where did you pull that particular one from?
my mods are edelbrock rpm intake 24lb injectors 255 fuel pump accel regulator b303 cam 77mm mass air and throttlebody long tube headers. the o2s are a year old last time i checked my fuel pressure it was good!? i replaced the plugs before i went to the track 2 weeks ago, the really black plug came from #8 and they go in order down the same bank 7 6 5 . the first plug looks like they gap is closed but actuallly the electrode has dropped down! im not sure on the heat range on the plugs but they are motorcraft awsf 44c.
oh ya and i compression tested all the cylinders on the driverside too all of them are even at 150+, and i was running 110 race gas. i replaced the plugs and it seems to run great but im still stumped
Check your timing and fuel pressure again. If those are within specs go 1 step colder than stock on the plugs.
Yea i have done that and well it did me right back, had to replace the trans after i did that last time.
i was gonna say, how muching timing are you running?
hey, look who else showed up for the contest. long way from hazzard county...lol :rollin:
im kinda diggin the skinny girl in the pics
Just reading threads and had to let you all know you have me cracking up..Susan Ann
P.s. 72 charger takes me back to first trip to drive in..opps my bad:giggle:
Just two good old boys, never meanin' no harm...
I knew Shawn would notice the girl!! :tg:
they actually played that song when the general was burning out!! ;)
(pssst, it's a '69 ;) ) :D
my timing is set at 23 degrees base and 42lb fuel pressure
as in fowlerville MI?
and not much of a contest when you have stop blocks.. then it is who's tires last longer and make the most smoke. :flame:
Yep, Fowlerville Mi. The blocks are mainly for safety, some of these guys get carried away. : ;) It's actually a car show, the burnout is just one of the activities. :D
Here's the guy who runs the show, 69 GTX, 440 tunnel ram dual quads, the guy has had it for 26 years. (also, he is not using blocks!!)
I live in williamston. I didn't know there was a car show going on! If you live in the area I will have to come see your car sometime!!! (as I don't have one anymore and miss the hell out of owning a 'bird)
edit: fowlerville free fair?
Yea, it's called the "American Dream Show", every year around this time. We're from Howell, the next little town down the road! :hick:
Last couple years, they moved it to the fairgrounds, more room.
I had my wedding reception in fowlerville.. yee haw..
23* base? wow
turn that down to about 14*, my car ran goofy as hell when i ran it at 20*
yah, I was gunna say something about that being a wee bit extreme but got side tracked by the closeness of the event.
Wow 23deg,what fuel are you running? Jet fuel?
Even with 14deg i have to run sunoco ultra 94 or else i get pinging.
Turn that puppy way down,15max.
my car doesnt really run good at 15? i usually run only 94 but i had filled up with 110 before this show. its kinda weird my car doesnt start hard or backfire???
is your timing marker correct?
I was checking that girl out too :D Just didnt wanna be the first to say something. Figured Id let Shawn have the honours :D But pics look sweet (meaning your car that is)
