HELP!!!!!!!!!.......(again)

[yellowfbod]

you have to have the entire motor rebuilt to replace pistons so depending on if you go back stock or upgrade rods, pistons, crank, blablabla it'd be like $2000-$3000 easy

wowwwwwwwwwwwww...that would realyyyyyy blow...i could probably just buy a whole new (used) one for that much lol...i just talked to the mechanic who's gonna be checking out my car...he's gonna start with a compression test on thursday to see which cyliders i messed up....hopefully no more than one...but god only knows...so i guess i gotta go from there

[White95]

you probbly fired your cat

White95 ...what does that mean?

( by the way...i dont really have a cat...its hollowed out...theres just a straight pipe through it)

So instead of saying "LOL" after people tell you you're crazy for running the stock fuel system, why don't you upgrade it?! You already know you've gone past the limits of it and possibly damaged one or more of your pistons, so why delay?

Upgrading your fuel system is as easy as an FMU and either an inline booster pump, or an intank fuel pump. Either way will supply you with the fuel demands, and the FMU will supply the fuel pressure. BTW, an FMU takes the place of injectors... so don't even waste your time with the 25lb ones from SLP, even though they are dirt cheap. If you go this route, MAKE SURE you get an adjustable FMU... not some crap-tacular non-adjustable EBay special.

While injectors and tuning would be the ideal setup, you'd need something bigger than 25lb ones, AND you'd have to spend an extra $500 on HPTuners software. If that truly is where you want to go, ZZPerformance sells 42.5lb/hr injectors for $200-$300 per set.

Don't do anything to your car until you get the fuel sorted out.

because it sucks...but its not the end of the world man...i learn from my mistakes...and boy do i make them...i wouldnt ask for help if i wasnt going to bother to do anything...i already have an FMU on the car...im looking at the walbro 255 lph external pump...but thats just going to be to support my 9 lb. pulley...i dont know that i'll be running nitrous again...i want to see what kind of times i can get all motor (well...a supercharged motor that is)

[NCState98]

WOW... just. wow. I've been reading so many of your posts lately, so many people telling you to take it easy (myself included) on your stock fuel system. Telling you to run just the blower until you got your fuel system up to par. I read your post in another thread and thought "what did he do?!", then came to this thread and saw the post about a 125 shot. I hate to say it, but you were asking for problems man.

whether you screwed up just one or all of them you will have to rebuild the motor, if just one is messed up and it DIDN'T damage the cyclinder wall then all you have to buy is a single piston but if it screwed up the wall at all then they will have to do a standard overbore to clean up the wall and you will have to buy a whole new set of larger pistons to fill the new bore.

one piston and rebuild=$1000-$1500
6 pistons, machine work, and rebuild=$2000-$3000

You can't just get an inline pump and not worry about the injectors. If he sprays with the amount of boost he is running with an inline pump his injectors will lock up. Mine started locking up at about 14psi so I'm sure with 9psi and a 125 shot it would do the same.

Ok, that might be the case, but IMO 25lb/hr injectors would just be a waste of time and money. You'd have to get the car tuned at that point to get all you can out of the new ones, so why not get the better matched ones for his power goals? If he got the SLP ones, after tuning, he'd still be using an FMU. The point of getting bigger injectors is to eliminate the FMU altogether.

But, I thought you could go 11's [img]tongue.gif[/img]

Sorry, had to put a bit of my sarcasm in there, enough of that.

First, stop spraying.

You need to address the blown set up first.

Dyno along with wide band, get results, then contact our sponsor who is involved with HP tuners.

125 dry shot, when I upped to the 120 dry shot I needed an afpr with raised fuel psi, kenne bell boost a pump, and custom tuned conmputer at that time.

I have since then ditched the kenne bell boost a pump for a granatelli 255 lph fuel pump.

I still run a stock rated 19 lb per hour injector and DO NOT run lean.

I recently changed from stock 90,000+ mile 19 lb per hour injectors to accel 19 lb per hour injectors.

I run slightly rich n/a now.

You need to focus first on the blown set up, tune, and then get back to nitous starting with a MUCH smaller shot

[Turbo V6 Camaro]

if you need big injectors i know were you can get 65#hour ones that work with our cars....... i have 57#hour and the runs rich as hell with out my turbo and the tuners didn't tune it right.

[1DangerousV6]

thanks guys...and thanks 12second for the nitrous info...im definitely gonna just take care of the blown setup first...my 9 lb. pulley is shipping out today...and my fuel pump shipped out friday...so first im fixing my pistons (if its not too much..if it is i'll wait till winter)...then im installing those...and i'll be back at the track on the 25 ...as for now i have a naturally aspirated timeslip thats not too bad...check it out [img]smile.gif[/img]

[1DangerousV6]

PS: crappy g-teh = no 11s lol ...and damn...the track is so much harder then i thought it'd be...but i got it down ;)
