Head studs and twins build !!!!!

Posted

ok - so I'm jumping the boat and going twins. I'm tired of fighting EGT towing even with methanol - dont want to go with reasons here - pm me if you need info on that one. I am guesstimate around ~400HP right now. I doubt I will ever go over 500-550 due to mpg and breaking my tranny :) So - I currently have a he351cw from john (AH64ID) here. Works well but want more. So underneath it as a primary will be a s472. My first step will be STUDS. This will be a longish thread. I am going to follow the ARP sequence and instructions for torque - you can get that here. http://www.glacierdieselpower.com/images/PDFs/ARP%20Head%20Stud%20Installation.pdf Likely to start in around 6-7 days after weekend :) Will be ordering twins shortly as lead time is around 3 weeks.

Should be over-nighted today and get here tomorrow ? :think: Then drive it WED. Cross fingers.will update with real world findings once Ive got it all in place. Rogan haven't lost track of our private PM convo - just been away since truck is down - and want to see what it does as its built now - will pm you again soon - thanks man.

    So. Results so far.1) Daily driving hardly any change - 55mph and 1-3psi and 550*.2) When the big primary lights - it seriously sounds like a supercharger/small jet - awesome :hyper:3) Full throttle hit 1007 but generally max is around 950. Previously probably 1200 but hard to be exact.4) Might have picked up a little extra "pull" in the band with higher boost ...... hard to be exact - feels goodDid I mention it sounds like a jet ?? :tongue:Anyway need to drag it up a big hill to get a better feel for EGT .........main reason for doing this as well as supporting future injectors. Will keep you posted over next 1-2 weeks. Right now I love having it - as expensive as it was ..........

    Sounds awesome! What psi are you getting out of each stage?

    Dont have my mechanical boost gauges in yet - so can onlyread off map.42psi with my +75 injectors. Looking to maybe do 150's .......... but will tow with it first and see.Yeah I need to get my guages to check my boosts and balance between turbos as well as drive pressure ....

    Is that 42 psig or psia?~42-44 psig is the max for the 3rd gen MAP sensor, and I don't see the 2nd gen reading higher, so I bet your boost is higher.

    psig Yeah I know the MAP maxes out pretty close to that hence need 2x mechanical gauges .......... I dont "think" I am much over that as I have only pegged it a couple times ....... and felt like I was pretty close to topping out with fuel ...... Will get the gauges in the next couple weeks ......... want to tow with it on and see where my EGT are at ....... and make some decisions from there. Id like to do 7x.010 (~150) and a friend is getting rid of his soon ........ but dont have a billet input ..........(neither does he !! hahah) hmmmm
