S/C gains with Shorty headers/Powerpipe?
Hey everyone for those that read my supercharged thread i put up a while ago i recently put down 370rwhp 325 rwtq. I have meth but its not tuned for it mainly wanted it for the cooling since I am in Florida running unintercooled.
I want to get the numbers a little closer to 400rwhp though. I was just going to tune it for the meth and reach the numbers but with this being my DD i dont want it to not spray for some reason (my tuner said snow performance has a tendancy to mess up) and go Kaboom!
I was thinking of different ways to reach my numbers and just keep the meth for cooling.
A- Shorty headers - found a pair for 150 around here BBK only worry that itll throw off my entire exhaust geometry and make things not fit properlly like my last exhaust.
B- Power pipe - i figure i can gain a little with this.
or instead of B
C - Go blow through put my air filter directly to the S/C and get a blow off valve (want to do this rather than powerpipe) idk what filter people are using when they do this though... mine is way to big to fit there. I should pick up some boost just as the powerpipe does due to less restriction, correct?
Any # estimates, or what would get me the closest to the magic number? perhaps both? Idk the gains for shorty headers. I know NA they are low but what about S/C?
Thanks sorry for long post

your going to have to retune to do that stuff. so since you have to do that i would ditch the meth since you dont trust it and put an intercooler on it.
shorty headers arent worth it. get longtubes, your in FL they dont even have inspections there. but reguardless shorty headers shouldnt "throw your exhaust off".
power pipe will add boost, how much are you currently running? if your already running 10+ psi, more boost is not a good thing (though adding the headers will drop your boost slightly also).
to skip the power pipe and go blow thru you will need a new maf. will be more expensive to go that way vs a power pipe but blow thru is a better setup.
and you can make your own power pipe with an air filter, an elbow, and some piping from oreillys. ton of people on here do it opposed to buying a 200$ pipe, works just as well and doesnt look ricey either if thats a concern.

Its getting a retune soon anyways when it gets warmer out.
I knew NA the shorties werent worth it but wasnt sure if it would gian more being S/C
I dont really wanna pull everything to install the LT's and get a new x-pipe etc. unless i find a good deal and go with a tube k-member down the road. If that is the case ill start hoarding parts until then
Boost yeah im right around 10 pounds i hardly ever get to see what it is maxing my boost out at If i remember it is 10? that was another concern with the Powerpipe. I read about people making their own as well that was another option
I am runnina a MAFia wouldnt nessecarily need a new MAF but at least a bung to put it in a new location. Shop can do all that stuff i would just need a BOV
Has any one had bad experiences with their Snow Performance or meth kit not spraying and blowing something?

IMO, since you'll need a retune anyway, and both shorty and long tube headers will both be a pita to install, i'd just do the long tubes. You could get a set of BBK's or Mac's used (with midpipe) for not a whole lot more than the shorties, and they will perform and sound better, especially with the blower.
When i did my long tubes i gained 20 rwhp & 57 rwtq on a 100 shot. No tuning adjustments were needed in my case according to my tuner. Before and after runs were done on the same dyno, so it was an accurate comparison.

LTs really aren't worth the money for the LTs plus install costs if you can't do it yourself for 20 rwhp for approximately 1K. Although, it will decrease your PSI but increase your HP which is a good thing for your motor.
Also a (1 PSI increase) you won't gain 10% it is more like 6-7%.

well ill throw the shorty idea out.
If i find longtubes and xpipe when i get a new k member ill go ahead and swap them out but not until then.
hmm... so i might be going the blow through route again idk what size filter people are using when they put the filter directly to the supercharger
probably should just tune it for the meth or be happy where i am at with it at this point
and start looking into weight reduction.
No one have issues with meth blowing things?
