your cam spec's in your engine

[vinces427bb]

does your engine even have a performance cam?
what engine size/family?
got any spec's for it you can share???

[vinces427bb]

well nobody shared their secret cam spec's with me so.....
i contacted Chris Straub, www.straubtechnologies.com for a better lumpy stik...
it's a custom grind, i'm told it will be at least 100-hp better that my firstcam that ran super hard.
now all of the work to swap it over.

[mopardude318]

have it installed yet?

[vinces427bb]

been working on it in stages.
cam is in and now i'm starting to button the rest of the items up
should have it running next weekend...

[vinces427bb]

got it back together and it fired right up,
sounded good, good throttle response,
started running rough, black smoke,
took it for a short ride, to put some fresh gas in it,
too late, started mis-firing, drove home and parked,
pulled 1-plug and found it black, new plugs only got 20minutes of time on them
crappy gas

[mopardude318]

oh no...im sure youll be up and running in no time with some new plugs! post some pics of your project, i like to see it!!

new cam is on a 112LSA solid roller with 232*/248* @0.050 & a 0.612''/0.590''
Good = runs nice/rev's hard, still a fair idle, my boost still appears to be max'ed at 12psi.
it does appear that i need to change to a more application specific torque converter to get more
out of my combo at this point
Bad = still evaluating the performance since i switched from a manual to T400 trans
hope to get a new custom converter to replace my off the shelf unit that only works ok

[mopardude318]

damn! nearly a year later!! i havent logged in since then! LOL

refresh us on what vehicle this is? yr, make and model, and with what engine? also why switch from a manual to auto?

[vinces427bb]

here is my current set-up

68-malibu, 4000+# with me in it, 10-point cage

Duration @ .050": 232/248
Lobe Sep. Angle: 112
Intake CenterLine: 110

T-400 no transbrake, GM25HD-Hughes converter
3.73-12bolt posi, 275/60-15 MT drag radials[28''-tall] 2''lowering spring on rear

i think this wants to idle @ 900-1100rpm, using 20*initial+14*mechanical for 34*total timing
i'm at a mile high altitude, have Msd6AL unit,SR-427bbafterinstall4.jpg

swapped in a T400-trans due to concerns about torque rating of 5-speed manual torque rating being far exceeded

Good God!!! damn, thats some serious stuff! LOL. those damn prochargers are awesome. i really like them. I'm waiting on tuning to come out for the 2013 Ram 5.7 Hemi. once available, its going on my truck! Ripp Superchargers already supports the 2011, and 2012's are coming out soon, so i have another year of waiting. lol

My B&M supercharger build i started last year came to a halt, ill get back into that hopefully in the summer time.
