Sharkbait needs help, im stumped.

sharkbait · March 7th, 2010, 11:22 PM

Ok so today I took my car out for its very first track day. Also happend to be my first day at the track.

Before today if my car got too hot at high rpm and full boost it occasionally feel like im losing power... kinda like its not pulling but rpms are going up. Sometimes it would just do it in little spurts.

Well today it started to do it again but now its after 4200 and its all the way up to 6k. It feels like its stumbling and like i have no power. I am having a hard time describing it but it feels like it just dosnt have any more.

I am thinking its spark blowout but im not sure. I think my plugs are .54 right now. Platnuim plugs.

But i dont know if thats it or not. I cant afford to just change them and see as i am very very broke.

REPS FOR ANY USEFULL INFO

if they are gapped that big then i think you have found your problem. Thats way too much for a blower.

.... get it down around the .032-.035 range brutha.

BakerFX4 · March 7th, 2010, 11:28 PM

mine was blowing out like crazy when i first installed my blower and was doing the exact same thing in the higher rpms till i found out it needed to be tightend up.

2 Problems. Plats are no no's with boost. And gap is too much, but you can't change plat's gaps since it just smashes the nipple. Swap em out with cheap coppers and you will be good to go!

Alright tommarow i think il buy a set of coppers.

Would NGK be preferred?
And autolite and mastercraft be good also?

Now as a reward for you all helping me

I run NGK tr6 with no problems. Honestly at 6psi i wouldn't sweat what brand to get, even at 9. Some don't like the ngk's and like champs or autolites.

I realllllly want to try the zex plugs.

BakerFX4 · March 7th, 2010, 11:42 PM

im a fan of autolite. autolite 103's are what i used to run. I will say though, that im not running a 2 stage colder NGK plug with no problems so either will be fine!

RyanGT · March 7th, 2010, 11:49 PM

Baker when do you run a 2 step colder? Any ideas? Never really found out... i know 2 power adders you do, but not sure what boost level you tend to.

sharkbait · March 8th, 2010, 12:11 AM

So your all fairly sure this is infact spark blowout?

RyanGT · March 8th, 2010, 12:14 AM

If it isnt blow out it is a shitty spark. Plats SUCK bad with boost. Combine it with N/a gap and you are bound to not be getting a good spark.

sharkbait · March 8th, 2010, 12:16 AM

Alright, cause i have msd coils and Frpp wires. I'll try this tommarow and see what it does.

IF it isnt blowout what could it be

RyanGT · March 8th, 2010, 12:19 AM

If it isnt spark blow out (should be replaced regardless) i would say inadequate fuel. Start at fuel filter. Or datalog it at wot would be best option to figure it out.

sharkbait · March 8th, 2010, 12:25 AM

Its got a 255lph pump, new fuel filter and 30lbs injectors and its tuned with a 11.2 a/f and it pops rich codes bi weekly.

RyanGT · March 8th, 2010, 12:27 AM

Then your rich fuel isn't being sparked

And damn that is rich!

RyanGT · March 8th, 2010, 02:25 AM

Tell us how it goes tomorrow. Ill be not paying attention in class and be waiting for people to post shit on MM

BakerFX4 · March 8th, 2010, 09:46 AM

ryan.... my tuner told me to put them in so that he could get more timing out of it at those power levels. SO i did it. dont really understand all that.

cruizer · March 8th, 2010, 11:07 AM

colder plugs decrease knock. Decreased knock means you can add more timing. At least that's how I understand it. You do have to be careful though if you live in colder areas. I have a buddy that has a grand prix gtp with three stages colder plugs and his car won't start if it is below 30 - 35 degrees out.
