KStang3.8 Posted December 7, 2009 Report Share Posted December 7, 2009 Its gonna happen this june. In the mean time i need to figure out the exact details so i can choose what to buy. I have 2 options. Cam. Or blower pulley. The pulley is cheaper by about $200 but i really am clueless to the performance difference and i'm also hoping to have somewhat reasonable gas mileage as this is going to be my daily drive for years to come. for the pulley: http://www.billetflow.com/supercharger_pulleys.htm Typical boost gains over stock pulley (3.65") 1.5-2.5 lbs. 3.400" 3.5-4.5 lbs. 3.100" 5-6 lbs. 2.930" 6-7 lbs. 2.760" or should i go with a Cam from Super Six Motorsports? whats the difference between Cam vs. More psi. In terms of performance (rwhp etc) and gas mileage (gonna kill it? gonna help it? no difference?) also is either thing gonna be harmful in the long run? like will more psi blow up my motor? thanks for the help. In case you need to know the M112 conversion kit consists of M112 from an 03 Cobra. Cobra Throttle Body and Plenum. JLT Cobra Cold Air Intake. Super six motorsports adapter plate. 39lb Cobra fuel injectors. 310lph Fuel pump from VMP tuning. Cobra 90mm MAF. and Water/Meth Kit Quote Link to comment Share on other sites More sharing options...
pontiacfreak142 Posted December 7, 2009 Report Share Posted December 7, 2009 well being that your car will only be the second one ive ever seen with this setup, i have no idea how much more boost will help. I would assume the cam would be the better upgrade though. How many pounds of boost will it see with the stock pulley? Quote Link to comment Share on other sites More sharing options...
STEVE-O Posted December 7, 2009 Report Share Posted December 7, 2009 I say cam it for a stronger drivedrain and it will help get the air in and out faster with that blower also... Quote Link to comment Share on other sites More sharing options...
pontiacfreak142 Posted December 7, 2009 Report Share Posted December 7, 2009 I say cam it for a stronger drivedrain and it will help get the air in and out faster with that blower also... quoted for truth because hes right. With a cam, the motor will breath a little better so you will take better advantage of the stock boost. Plus it will be much easier to do the cam swap now since you will already have the intakes off and such. Plus you can always do the pulley swap down the road fairly easily and again, you will see better gains because of that cam. edit: although come to think of it, before you decide which to get, id figure out what your long term plans for the car are. Because if you go with the cam, to really take advantage of a cam, your more than likely going to need a torque converter. If you dont think your gonna want to spend the money for one, id just go for the pulley. Quote Link to comment Share on other sites More sharing options...
Guest JCroz91 Posted December 7, 2009 Report Share Posted December 7, 2009 ugh the gains in that link will not be what u will see out of ur car. ha essentially the larger the pulley you use the more power you will make. this blower isnt made for our small engine. it makes too much boost for our small engine. do a 3.6 pulley (stock pulley) and call supersixmotorsports and tell them you want a cam. they will ask u your future plans and goals for the car along with all ur curent mods to make a cam perfect for your setup. i was quoted $350 for the cam an then with springs, rods, and retainers it came out to about $650-$700 in parts then about $700 or $800 for the install. if you go any bigger than a 3.4 pulley ur engine wont last long at all. with stock internals a smaller pulley isnt an option. cam, RR's, meth injection are your only options other than building the motor. a cam should add like 60ish rwhp cause it will let the engine flow better, add LT's to that and you will see better #'s. all in all with stock internals most you will see is around 300 rwhp.

Main3s Posted December 7, 2009 Report Share Posted December 7, 2009 I'd go with the cam before the pulley as well. The added boost won't be worth a damn and will cause more problems then power if your drivatrain can't move the air. Quote Link to comment Share on other sites More sharing options...
KStang3.8 Posted December 7, 2009 Author Report Share Posted December 7, 2009 @ Gary - I'm not sure what stock boost is. 7-8ish maybe? my long term plan is basically this. because as i mentioned i want a daily driver. while i'd love to make this into an 11 second monster i would have horrible gas mileage at that point and i can't do that. @everyone - sounds like the blower pulley is not the way to go with the stock internals, which i feared, thank you for the advice. @ Jcroz - "i was quoted $350 for the cam an then with springs, rods, and retainers it came out to about $650-$700 in parts then about $700 or $800 for the install." on their price listing thing it says 400. so youre telling me i have to fet the srpings, rods, retainers and drop 650--700 for it? then double that for install? cuz damn. if thats true i can NOT put a cam on my car. also. what kind of gas mileage (mpg) do you have with your setup? and how would a cam change that (for better or for worse?)

KStang3.8 Posted December 8, 2009 Author Report Share Posted December 8, 2009 ya i think i'm just gonna accept whatever i can get with just the blower, no new pulley, no cam. too much money and too much risk to kill my car. have you had problems since you m112'd yours? you said youre giving up on it is that cuz its killing your car? or what?

Guest JCroz91 Posted December 8, 2009 Report Share Posted December 8, 2009 no i havnt had any problems. but its just if you try to add any more power the chances of going boom get very big and i want too keep it safe. its about at fast as a slightly modded gt so its a decent car. when it blows up ill put a v8 in it to get me by.

KStang3.8 Posted December 8, 2009 Author Report Share Posted December 8, 2009 okay i feel you. that sounds better i was worried for a minute lol. any suggestions for better gas mileage over your setup? would you reccommend getting the underdrive pulleys that you have or no?

Guest JCroz91 Posted December 8, 2009 Report Share Posted December 8, 2009 i have a steeda UDP. idk what its like to not have one. it was the first mod i ever did to my car. but if you want better gas milage dont put a m112 on ur car. lol theres no other way around it. ull need to have premium all the time now too. a full tank lasts me maybe a week. and i work and go to school both full time. so im not out driving around a lot. thats $40 a week. another reason i got a bike... 45 mpg and $10 to fill the tank which lasts me about a week and a half. in summer i plan to nearly never drive the car and just take the bike everywhere Quote Link to comment Share on other sites More sharing options...
KStang3.8 Posted December 8, 2009 Author Report Share Posted December 8, 2009 well right now i drive like a crazy man and i get about 15mpg so i know what its like to have 1 tank last one week. and my parents pay for gas till i'm out of school so thats like 4 years free gas unless they go bankrupt because i use so much gas lol so. i think 13-15 will be acceptable enough for me. shitty as it is...it will be acceptable. in terms of exhaust i have bbk shorty headers stock cats and y pipe and magnaflow catback. should i invest in high flow cats or LT's? if so why? is it really worth the extra $ ?

Guest Removed Posted December 8, 2009 Report Share Posted December 8, 2009 you can get better MPG out of the tune... dont do just the cam, you have to upgrade the springs and all that. and why run meth on it? i dont think your really going to need it, unless you are really pushing some boost into it. or unless you hit spark knock on pump gas. why not just turbo it.?

KStang3.8 Posted December 8, 2009 Author Report Share Posted December 8, 2009 well. i don't wanna turbo it because i already have like 1/3 of the parts including the m112 for this. and then also the cheapest TMA kit is 3400 and this is gonna cost me 2400. as for the cam thats gonna be more pricey than i want. i was going to run meth because Super Six recommended that i do and sonic is as well. so i just figured it was the thing to do. you feel its unnecessary? can you explain why? i really wanna go with longtubes. lets say i can't. would high flow cats be good?

KStang3.8 Posted December 8, 2009 Author Report Share Posted December 8, 2009 stock boost which i'm not sure what that is but i'm guessing like 7-8ish psi? Quote Link to comment Share on other sites More sharing options...
pontiacfreak142 Posted December 8, 2009 Report Share Posted December 8, 2009 meth is not necessity for that little boost. Any idea what the compression on those motors is? Kevin, you best bet is just to get some long tubes, and save your money and just remove your cats. You can usually get a muffler shop to bend you up a pipe to take the cats place. Just dont tell them what its for lol. And as for gas mileage, its all about how the car is set up and how you drive. For instance, about a year ago, i put a full tank in my firebird and with a mix of city and freeway driving, along with beating on the car from time to time, i got an average of 27.5 mpg, and thats with a very rich A/F ratio to lol. Although with the 4.10's im about ot put in, i expect that will go down. But wow, i always thought the ford 3.8's were stronger than that.

pontiacfreak142 Posted December 8, 2009 Report Share Posted December 8, 2009 im not quite sure what all meth does, so some one will have to awnser that question, but i know several people running a decent amount of boost on GM 3800's with the top swap (different motor, but same concept), and they just run 93 octane.

2pointslow Posted December 8, 2009 Report Share Posted December 8, 2009 2400 for nearly 300whp in a stang? Why not just buy a v8 and swap it in? Quote Link to comment Share on other sites More sharing options...
Guest Removed Posted December 8, 2009 Report Share Posted December 8, 2009 stock boost which i'm not sure what that is but i'm guessing like 7-8ish psi? shouldnt need meth for that... meth is normally used when people dont want to run race gas under heavy boost.
