Lots of upgrades...where's the power?
So I just recently took my car in for lots of modding and just got it back...
MyPowerMods: K&N Intake 2.6 60 siemens NGK irradium 2 steps cloder ZZP shorty Header ZZP Catless 2.5 Downpipe Corsa Touring Exhaust CA Heat Exchanger Dual Bypass End Plate Meth/Water Kit.... Elavation- 2200ft So here's the scoop with all that i was expecting around 280whp considering what i've seen from the Dyno Thread on here and some peoples Mods...But I ended up with only 256whp on the Dyno :cry: I was like what the!? This makes no sense to me at all and can't wrap my head around it...My AFR is saying 11.9 at WOT on my wideband gauge...is it a bad tune or what?? should it be running leaner more like 12.4 or something?...And i also lost quite a bit of Low End right up to 2500rpm i'd have to say:thumbsdow....And another thing...is the AFR suppose to jump around even when you have cruise control on at the same RPM?? I don't alot about tuning yet so i just thought i'd ask.. I also have crazy misfires going on at Idle right on up to about 2200rpms then stops... it's also not Idleing at all like it was before when i brought it in bone stock... its all over the place! Please Help or explaination whats going on...I don't know where to start or if i should just get another tune by someone else.. |
2.6 is killing your supercharger thats why. your way past what is effiecient power and just generating more heat
also are those dynojet or mustang dyno and yes at any steady rpm the AFR will be searching and go anywehre from 14.4-14.8 usually trying to get the perfect 14.6 |

cooling mods FTMFW...
|
lots of guys are running 2.6 with my mods and seeing bigger numbers than me....It was a Dyno Jet....i should have enough cooling mods my temps all read normal...so that ain't
|
i pulled the same numbers on a dynojet with just stage 2, intake, headers back.... 260 / 240

my car that did 253 whp, it also trapped over 86 mph in the 1/8th. Take it for what you will but dyno numbers are just that numbers and nothing more.
|
i agree. to the op take it to the track and see
|
get the tune sorted out, obviously you have issues if its not idling properly. sort that out first, drop down to a 2.7" pulley and retune it, then see what it does.
|
i made 253hp and 240 ft lbs with
2.7 60s injectors Meth, with Boost juice K&N intake and stock exhaust run a bigger pulley man |
Your plugs are way to cold and your pulley shouldn't be less than a 2.8"
Get some nice copper BKR7E's and your set. Also check your meth, if your spray too much you'll loose power also. |
Too Cold of plugs? lots of guys are running 0.35 gaps on their plugs... does anyone know what a good AFR would be with running Meth
I'm thinking it must be mostly in the tune....just stage 2 alone with no other mods is suppose to be 241whp and i only ended up with 15 more than that....lame |

"Cold" refers to the heat range of the plug not the gap size. Also, Copper plugs are best for boosted cars as they have a better heat charge. They go out faster but they are a better more reliable plug. Iridium's are nice but not the best plug option for a boosted car. |
iridiums not good for boosted cars? are you kidding me? they are the only plugs that don't blow out in my car. Anything else I've tried runs like shit.
|
With the crazy cyl pressure's I run I use the 2 step colder brke8ix I think is the model. I've tried the copper, they just die out after 2-3 weeks, zex, well I"m not getting into those. But I've had these NGKs in my car now since I first went turbo about 10k miles ago. and they still function good as new, no spark blowout, no studder, nice and smooth each time everytime.

eh they just blow out on my car above 6300 rpm, with the brk's I can run straight to 7k without a hiccup

I would, since I swapped through everytype and only one worked out with no issues

what??? hes running a 2.6 dude, those plugs are fine
I know what pulley he's running. He asked why his car is screwed up and I'm giving him the correct info so he can use it to fix his cars problems. Blower shouldn't be pullied below a 2.8", a 2.9" if you want it to be happy.

Just thinking aloud here. |
i don't get why people get so upset over a dyno #. it's just a #, and in all reality it doesn't really mean anything unless you're using a dyno to tune.

Maybe the coil packs can't deliver a hot enough charge for all the air your cramming in.
