BIG PROBLEMS WITH SUPERCHARGER INSTALL

[doubleomustang]

doesnt sound too good to me either. i would say you leaned it out pretty badly and either have piston damage or valve damage from the spark plug tips. the 30# injectors will most likely be a problem also. you should have 42's in there

i would do a compression test first off to see if the engine is still any good.if compresion is good then you should be ok with a new tune

if i get 42# injectors can my current MAF sensor be recalibrated for those?

 

[doubleomustang]

the exhaust leaks will difinitely cause it to run rough and cause the backfiring you have when you let off throttle.fix the leaks first and go from there.you have suffered detontation, but the backfiring is from the leaks

i understand that i have suffered detonation but is it possible that nothing was harmed in the rotary assembly and the fixing the exhaust will fix the rough idle. as soon as it started driving rough i shut her down and havent driven it again.

you should run at least 38 lb injectors...that's what i run...42s would be a better bet though

well im hoping for the best and saving up for the worst. i think im going to have it towed to a exhaust shop soon to have the exhaust straightened out then i think im going to let this place in anderson ( Amazon tuning) take care of the rest. if i have ruined the valves in the two cylinders that ate the plugs al that would need to be done would be to pull that head off and have new valves put in right? i dont think that i have piston damage. i think that the engine would run alot rougher if it were piston damage. i have really bad exhaust leaks right now and im wondering if the rough idle might be due to that. i really appreciate all the suggestions an help that has been offered so far and welcome more of it.

You won't know until a compression test is done. That should be your first step.

i just got 42# injectors and a lightning MAF. im going to have the car taken to a local garage to have a flow through test done on it to see if i have to replace the heads. if i do need to replace them what aftermarket heads would yall recommend. i was looking at gt40 heads from ford racing. in opinions?

 

[deftsound]

its made by professional products and i think its a 80mm iv had it for a while and i felt a big difference with it a ported stock plenum and a K&N CAI so i dont see why 80mm would be to big especially with forced induction.

you're probably losing some power with the 80mm. 75mm is right where it should be but it wont hurt anything having an 80mm just like i said you are probably losing some power with it...

If you have an exhaust leark before the oxygen sensors it makes your car run like ****. I would get that fixed and then you can order a tune from any sct dealer and they can e mail it to you. JMS Chip and Performance does it. Probably MPH and others do too. You need to do a compression test but fix the stuff you know is wrong first. You should have more like 350 hp.

i did have an exhaust leak before the 02 sensors. i took it to a exhaust shop and they said the they could get a finger between one side of it. i had them line it up but i didnt want them to start it and run it because its not running right so i wont really know if it is still leaking till i get it running better. it will run but the passenger side bank still sounds really bad.

Where did you get your maf and tune? Did they come with the supercharger kit?

MAF came with the kit. the tune came from SCT and it was dyno tuned at a local dyno that isnt worth anything.

 

[blubullett]

I would do a compression test next then or send it to a shop that can do it for you. If that shows ok then send it to a dyno shop and have them data log it while its running on the dyno. Some guy said something about a shop called Amazon thats near you. Im outa ideas. Good luck.

yeah im going to do that. do you if i can calibrate the new MAF with the hand held tuner and does anyone have a suggestion on heads if they have to be replaced?

 

[blubullett]

The maf can only be calibrated by the maf company. Your dyno tuner can adjust the fuel trim in the tune, which can adjust for a wrongly calibrated maf, or you can do it with the tuner but you have to hook it to your computer and use the software they give you with the tuner. I highly recomend you dont mess with this at all unless you are trained, have a wide band oxygen sensor and a dyno, or money for the new engine you will need after you accidently blow it up.

For heads: VT, MMR, or Fox Lake. Stay away from Patriot....

 

[kj99]

Hey "double", I would make sure you do call Rick at ATS amazonracing.com to get your tune done where it's safe.


I had my car tuned by rick last year. And not had one problem so far with my car.




Oh Yea, when you do get everything worked out, I think we need to run each other. lol


Your from spartanburg to?? It would be a good run I think..

 

[xmikevankuikenx]

Take your car to Pro-Dyno. It's beside Carowinds on the NC/SC border. They are hands-down the best SCT tuner in the area. pro-dyno dot com.

probably blew a piece off the pistons above the top ring

I don't even know who makes an 80mm TB for our cars.

You can get an LMAF in 80mm.
