New here +motor build up ?'s

If grout acts anything like concrete it takes quite awhile to reach full strength. In fact good concrete keeps getting harder. Also there are some grouts that actually expand when they cure so if that stuff keeps changing you will be changing the stresses on the block after you machine it if you do it too soon. I'd call the manf and ask them about it.
 
:iagree:

From my understanding concrete takes 28 days for a full cure.

Anyone doing this take taper and out of round measurements before and after?

Are you going to stay with stock compression?

Uhmm well I'm kinda new to the whole turbo thing and diesels. I'm kindof unsure as to what I'll end up running. I know you run 16:1 from your sig but I'm thinking of staying around 19-20:1 possibly. What are your thoughts? Seems like a lot of people are running 18:1 but seen a few complaining about it some so I'm kindof just going off what I read basically

So yea I don't really know a whole lot about what to do with that honestly. I know gassers somewhat and a lot of the stuff carries over but not quite...
 
Lower compression means higher boost can be used safely. Down side is the lower you get the harder it starts. Longer glow cycles can be programmed or a controler can be had.

22:1 or 21:1 is normally stock. There has been some recent showing of these engines with high boost and doing quite well. Bill Heath's land speed truck is 22:1 with twin turbos (don't know type) @ 30 psi I think. ATT on a stock truck pushes close to 20 with ease.

I know everyone has their ideas and stuff over what is best and there will most likely be other opinions shared.

I think going below 20:1 is worth it if the engine is already apart but I wouldn't go out of my way just to change it if all is well.
 
I dont think lower compression ratio is necessary. I run stock engine and heads and run 20psi with GM4 and close to that with ATT. The ATT doesnt do it on all stock, needs an aftermarket PCM program and large free flowing exhaust. Things I would assuredly do before or when purchasing a larger turbo.

IMO Anything lower than 20:1 is a pain to start, Slim's truck is a 18:1 truck and he said if he did it all over again he wouldn't do it. The truck is hard starting all the time and smokes everytime on start up and its not because of any injector or pump problems. Its combustion temps are to low on start-up

My truck is of stock compression and even on cold start-ups it hardly smokes, and starts easy. Your going to saying a few choice four letter words when your trying to start it on a cold morning without a block heater:D
 
Yea I kinda figured on that one lol. Probably do a lower hose heater or a stick job to help with the cold starts. Got a new block the other day but had guard drill so didn't have time to tink with it yet

hank1948 I read a thread earlier where you had machine the head precups out bigger. I didn't see too many other replies about this after the fact and was wondering what ever happened with this? Any power or mileage gains? Kinda curious...
Thanks

I definitely noticed a difference in power, I haven't done any 0-60 performance after results since my ATT turbo is only puttin out 10psi (havent had time to find the exhaust leak) but when I do I will be able to post results. I have already got the pre 0-60 results, pulling a 32ft 7500 lbs travel trailer.

If you want yours done (precups) I can do them for ya. I ve done a set already for a member

What would this cost a guy? Does it matter what pre cups you start with?

If you feel more comfortable PM pricing info.
