OK, When I installed my new turbo I end up removing the vacuum pump and installed the 99.5 belt. I also disassembled the A/C system and cleaned everything to the extreme and installed the new compressor, dryer, condenser ect. (It's Florida and heat is here NOW). A while back I talked to Bill and...

Thanks guys! Good info! I was comparing prices and it seems the Walmart 2-cycle oil is about the cheapest in my area. BIO is too far for me to travel to get.

Hey Guys, I have been running the Walmart 2-cycle marine oil for a while based off what alot of people have been using with great results. Now my question is since there has been testing of this specific oil can we use any other brand of 2-cyle oil?

When heat is applied (back pressure) to a closed gas system, the temperature increases because the molecules begin to move faster. Faster moving molecules try to expand the volume. If the volume can't increase, the pressure increases. If the volume is allowed to change, it will increase and...

Matt you pretty much have it except, turbos unlike blowers do not use power to run them. A blower will require HP in order to run them. So let's say a 671 requires 50HP to turn it and the motor duynos at 500HP it actually makes 550HP but the blower robbed the 50HP first. The bigger the blower...

So... your saying that all turbos flow the same amount of air for a given psi.... And that the only difference is that a more efficiant turbo can provide a given psi without producing more heat? Boost is erelavant and only a unit of measure. I'm not here to disrespect anyone but going by this...

Absolutley Buddy, Less pressure but more volume of air. I am in no way trying to take anything away from the ATT. Slim and Doc are awesome people. From what I have read Slim makes a 100% bolt-on solution for a incredeble price. I fabricate and use to do it for a living so I enjoy improving my...

Right now I am running a T4/T3 hybrid. The turbine is the same as a Holset HX40. But the Compressor is in between a 62-1 and a T61. I was thinking the compessor was a bit on the large side but since the initial break-in plus the PCM learning it's curve it seems to get better and better. If I...

I always had smoke at WOT. Dave you are right as far as the TCLU I just didn't go that far into the description. Bill told me 13psi max and I left it there. I was averaging 19 mpg with the GM-8 turbo with no trailer. Now with my Big Garrett turbo I see 10psi substained and 12psi spikes, but it...

Now I will say with my current setup the truck really moves on the entry to the interstate with the early high gear shift. My turbo pulls much harder mid range on up compared to the GM-8. Still not done testing but It is about the best it's going to get. If I can keep my foot out of it I will be...

Mine is a 99 and my original PCM ran 12psi with the factory vacuum actuator. When I changed over to the TM I really didn't see any difference except for turning it up to 15psi. When I got the GLE, the only thing I noticed was the fast shift into high gear. I didn't really notice any power...

Great write up with good pics!!!!!! How it running now? No more symptoms?

+2 o m g roflmao!!!!!!!!!!!!!!!!!!!!

Go deal Matt! I wondered when I bought my 225's if I should have gone to the 235/85/16's instead. Also wondering in the future I wanted to go maybe 22's with a 305/40/22. With these the height will be 32"! I was thinking a gear change will be neccessary when (if) that time comes. Sorry got...

Absolutely, I have had the piston pin offset bored and pinned along with resizing the big end offset to get the length I needed. No never .030 off one end I think that would be too much for either end by itself.

If you have no 18:1 pistons this is another way to acheive your goal not just an option. ccing the chambers and deck to determine what you can do is a normal practice. While it can get into a expensive option depending on which way you have to go. As Packratt stated his combination would work...

Sorry AK, I was just using the 383 as an example. It is nice now a days buying a 383 kit and simply building up your engine. Back in the day there was a few routes you could go to get the 383 combo and you had to machine the parts to fit.:thumbsup:

Let's look at this...... $750 for 18:1 pistons $425 for 22:1 pistons You need to rebuild your rods when rebuilding your engine using either piston. Matching all the rods to the same length is basic blueprinting and should be done regardless. Just have them shortened .015 - .025 and...
