Group Buy: MAP Ultimate Duty Head Stud

maperformance · 08-09-2012, 02:10 PM

PRICE $220

MAP Ultimate Duty H11 Head Studs (6 and 7 Bolt DSM)

Consider these an insurance policy for your head gasket...

If you're looking to make big power (proven over 1000+whp) but don't like the idea of lifting your cylinder head and replacing head gaskets frequently these are exactly what you need! These studs are manufactured specifically for us by A1 Technologies and utilize an H11 material that is much stronger than the typical 8740 chromoly and yields a tensile strength of 260,000 psi. They are also provisioned with a hex broach on the top of the stud enabling you to install them with the cylinder head on the car if necessary.

What is so different about these head studs?

At first glance these may appear to be similar to the other ARP and A1 Technologies head studs available on the market, but that is simply not the case. The MAP Ultimate Duty Head Studs include an additional feature known as a "dog point" (shown below) that seats the stud in the block and preloads the fastener for an accurate and repeatable torque sequence.

Count me in for a 6 bolt set.

maperformance · 08-14-2012, 01:55 PM

Only need 3 more people to lower the price to $210. If you are building any type of DSM block these are the studs you want.

agentorange313 · 08-18-2012, 12:04 AM

I need a set, 6 bolt please.

urbansmoker1 · 08-18-2012, 02:48 PM

how much boost/lb per min can you run with these.. and can you install them with the head on if i currently have arps, i know you say that in the op but i know that the washers go under the head so would my current arp washers still be fine if I'm dropping these in with the head on?

urbansmoker1 · 08-18-2012, 07:06 PM

someone answers this for me i'll join the buy..?

(proven over 1000+whp). What do you mean that the washers go under the head? They go under the nut so you can easily swap these in when you are installing the studs.

yeah 1000+whp isnt really specific though whats proven mean? whats the proof?. i havent installed the headstuds myself i just thought i remember seeing a head stud install thread that said the washers had to be under the head? Or something like that. if your saying its just block gasket head sandwiched down, washer then nut then torque, then i understand

i also understand that to do this with the head on, you would un-torque one head stud remove it install the new one re-torque then move to the next?

i pretty much want head studs that i can throw as much boost as i want at it with this Holset and not have to ever worry about it. ive been considering magnus headstuds but these are quite the deal. i believe magnus has the dog point also.

How is 1000+ not specific enough for you? That means that they will hold at least 1,000 horsepower. Proven would mean that they have been installed in an engine making 1,000+ horsepower and held up. The washers do not go under the head, if they did than the head gasket couldn't seal.

urbansmoker1 · 08-18-2012, 07:32 PM

ohhhhh.... people say install the washer before the stud meaning seat the washer in the head then stick the stud in and tighten it with the hex bolt then torque the nut, do you have to torque the hex broach going into the block to a certian spec? or just good n tight.

Yes, install the washer in the head than slide the stud thru it. If you install the stud first than the washer won't slide past the spring easily. The stud doesn't have to be torqued, usually just snug with an allen wrench.

alright cool i ask because my current studs were installed with a torque plate. im guessing the lube goes on both threads only correct?

maperformance · 08-21-2012, 01:12 PM

Yes threads only on the lube. Hand tight with and allen is fine for the studs and then torque the hex nut. Only need 2 more people to lower the price!!!!
