my block is still pretty much stock i am wondering if I went to 90hp sticks and a bigger turbo if I will be ok and close to the 400hp range. Or am I looking at head work? I am already planning on a better fuel system either FASS or airdog to fuel the bigger sticks. everything else is in the sig

what about ideas for turbo

mysterync

A 62/71/12 or the new ED 62/68 Charger. You could run 100 horse sticks and be fine but eventually no matter how you mod your truck, It'll have to have a head gasket.
It's true that high boost numbers HELP kill head gaskets but drive pressures and timing are the real head gasket killers!

quads4_life

Yeah I am not as worried about the head gasket as much as I am the 53 block but as things break on the truck I am replaceing with mods. so when the head gasket blows I will fix with 12mm head studs

where can I get those chargers at? and about how much do they run?

mysterync

Engineered diesel is what ED stands for, They build more of a custom charger than others.
Industrial injection and HTT seem to be most folks favorites. You can have the 53 stiched if it were to crack. It's not a structural problem...just a leak problem.

What do you think about the ATS Aurora 3000

DodgenIt

Ive never heard anything 'bad' about the ATS turbos, but very few people on this forum seem to run em.

A super phat shaft from I.I. is a 62/71/14.
If you did F1 Mach 1.6 (real good, cool & clean 90hp) sticks I bet you could run a HX-40 (60/65/14?) or a Phat shaft (62/65/14) just fine and hit the 400 horse mark.
JMO

But you might wanna call ED cause Ive heard good about them as well, product AND price.

For sticks I wouldnt run any other then DDP or F1 in my own truck. Thats just me.

Also, as long as you stay under 40-45 lbs of boost, head studs shouldnt be needed. But Im pretty sure with the right fueling you could spool over 45 lbs with any of the above turbos if the waste gate isnt set to open.

I'm running my wastegate at 40 pounds with what you see in my sig. And it will run 12s in the 1/4. I had to replace my headgasket at the 210,000 mark as it had eroded at the oil passage in the front of the block it did not lose compression around a cylinder. Throw some mach 1.6's in it. Retorque the headgasket. Put a HTT 62/65/14 on it and have fun. My 53 block has 260,000 miles on it. Most of those miles have been modified miles and 85% of the miles have been pulling a horsetrailer, haytrailer, or fifth wheel.

There's more to head gasket failure than boost. We must also consider timing and drive pressures. Sometimes a undersized charger is just as dangerous as a bigger charger. I honestly feel the 65 wheel creates to much drive pressure and egt.

mcoleman

I'm running less than 1 to 1 ratio on drive pressure with a 65 wheel in my 66 charger at the 40 pound level. Not had any problems BUT, there always a but, I'm smart enough to not use my stage 2 water/meth set-up or the nitrous until the studs and orings are on. Also wanting to do a bunch of dyno work at different boost levels just so I'll know how much difference the added boost makes. I think the truck should probably be set around 50 pounds with my set-up and I'd like to see if there is a hp or torque difference over the 40 pound setting.

You'll be very close to 400rwhp with a edge comp box, mach 1.6 (90-110 size sticks). You'll be on the toasty side. I would just spray water not methanol/H2O as you need more air for the extra fuel. I'm getting close to 500rwhp at 3500 ft, with my little 110 sticks.I have to run the throttle hard into the floor to break 1100 deg's. Spool-up is as good as stock. With more air you can burn more fuel.

mysterync

Driveability will increase along with cooler egts thats for sure! My 65 turbin wheel did fine until we started pushing the limits and egts and drive pressure went out the roof!
It's nice to see someone with a Manifold pressure gauge!! sounds like youve got a nice setup goin!
We had a argument on a duramax forum in regards to the increase in cylinder pressure with water meth, the manf claims that theres no increase. I personally feel your being smart waiting on studs and rings for water. I feel anytime you add a vapor (water meth) to your intake gases you increase cylinder pressure plain and simple. The companys argument was that when the water flashed to steam it in some way lowered the pressures ( im guessing in theory lower temps, lower pressures) .

I was lucky with my NXpress 2 stage...No head gasket failures or charger failures. We went to the 66/71 before the nitrous so i couldnt comment on drive pressures. What nitrous setup are you using?

Mike Holmen

At that power level, orings aren't required. The normal ARP Studs are fine with a stock head gasket. Crank the studs up to 135 ft*lbs, you'll be good for 50psi. Orings are really for the trucks running over 65psi. So its over kill for low HP truck.

mysterync

Mike, I didnt even know you were running around here any more!

Sorry we got off topic , we were talking about another truck! (mcolemans truck)
