Yeah i got the motor in,made it to the race,no time to T&T,went straight into qualifying after 3 rounds i was 5th out of 29.My fixed dial was 11.06.In the 1st rnd i had a competition bye.In the 2nd rnd i won by .0005 ten thousands of a sec at 11.09,3rd rnd i won with a 11.063,4th rnd i won with 11.061,in the finals we got rained on & will conclude June 18 & 19.

Even with proper spacing setup the converter can, and will, balloon if he is on the transbrake too long.


Yes


You won't. Nothing to balloon. You're fine with a manual transmission.

Never tried it with a 4R70W and just don't know, but is there a way to use a converter bypass like on the glides or th400s?

 

[BossBob]

I don't believe anyone has tried that, Bill. Just not enough people using the 4R in ultra high hp applications with a transbrake to warrant one of the companies to try it. Once they go over 1000 hp most people make the switch to a 'glide or TH400 setup.

New progress

Here is the car getting ready for paint. Yes the car has to stay outside cause all the bays are used up at work.

Here is after paint.

Oringing the block and using SCE titan gaskets. .043" thick.
I have 3.750 in stock but they wont work with a normal style oring. I would have to figure 8 it. I will have to order the other set tomorrow.

For those of you that dont know what Oringing a block does is it pretty much takes away any room to fail in the head gasket territory.
You take .030 of a groove out surrounding the bore and install a stainless steel wire in it making a perfect ring. You want to put the ends where both part of the ring connect as close to a head bolt as possible and make it perfectly flush. Then you use a SCE copper gasket and when you torque the head down, the stainless steel crushes in the gasket. After talking with my tuner (Lito) we came to the conclusion that where im going with the 88mm that it was a good idea to do.

I almost o-ringed my block while I was in there.

Now where is the next weak link, LOL.

I started to pull my heads apart and clean them up and do a 3angle job to them. I have to replace all the guides cause they are very loose. The exhaust were the worst, due to the 2 piece manley inconel valve that Livernois uses. The inconel disperses heat, but the second half of that valve thats steal doesnt and passes the heat to the bronze guides causing them to loosen. Typically you would want about .0015 clearance. I only have about 4k miles on these heads.

Holy Shit Paul,when will you have all this back together?What happened to a 10.50 daily driver/bracket car?

Randy, my heart wants to go fast and my pocket and reality wants to dial back and run a index class. Since I had the car apart, I set it up to handle what I can throw at it, in case something changes and allows me to really do what I want. I will make some new passes with the new new motor and converter to go faster than the 9.66 141.

It should be running tomorrow after noon. I just have to pick up the converter in the morning and install the trans. The motor is back together for the 3rd time, hopefully I have this thrust issue fixed with the trans. I really am thinking that it is the cooler lines that did it.

Wow,you don't fool around Paul.I really hope it was the cooler lines that caused the damage.Keep me posted.Maybe you can make it to NMRA in Columbus on Labor day weekend?

Well I got the motor back up running again. Ive been driving around getting in and out of boost to seat the rings. Everything seems good. When I picked up this new converter, he cut open the old converter and said everything looked good. No signs of ballooning or wear. So the cause of my motor going was the trans cooler lines. First sign is rattle around the flexplate which is the starter gear hitting the flexplate at startup. Another sign is transfluid coming out the bellhousing and leaking pretty badly.

What to learn of this is not to order stainless braided lines from this company. http://anfittingsdirect.com/ Their lines are small. Thier -6 are -4. So if you do order from them, get the next size bigger. They are the same company that many people order turbo kit parts from. http://siliconeintakes.com/

So basically a few fittings and lines costed me 1 engine and caused the newly built engine to have to come apart and have the crank fixed.
Thank god I build engines or this could of costed some serious coin.

Special thanks to Billy (07 supercharged) for the good deal on the block.

...just...wow...

I learned the hard way; I cant do it myself, im outta my league.

Verry interesting/impressive build.

Amazing build...

Yea Chad, it sucks when you get it back together and think that the motor went from sitting on the transbrake too long. I thought that time after time, sitting on the brake just ate the thrust bearing. I was wrong, I changed trans lines and it took the block, pistons, and crank out. Well when I took it apart, I realized that the Livernois stage 3 heads had shitty guides put in. They were on the way to take out my seats if I left them in any longer. They were pretty bad. I recommend to everyone that has a set of Livernois heads to check out the guides. and see if they are going bad. I know Lito had issues with his guides also.

I had to change valve guides on a set of Livernois St. 3 heads with 1,500 miles on them. They were all junk after that little bit or mileage. Not a good thing for a $3,500 set of heads.

Just curious, did you check trans cooler line pressure before and after changing them out? I'm glad you got it fixed and it was a simple fix.

Never checked the pressure cause nothing was changed except the cooler lines. I had 3/8 line and changed it to -6. -6 is the same as 3/8 usually. I know many people using -6 on the trans cooler lines. When I actually took it off and ripped the fitting apart I then seen how the 90* -6 fitting steps down to under .125 (1/4") and when I tried to breath through it, I felt a big restriction. This was after the crank and main bearings were toast the second time. The crank was repairable for 200.00. Just the thrust face, not the mains or the rod journals. The backside where the flywheel bolts go through. If you were to stick a longer flywheel bolt through and it would come out the other end that is where it got damaged. Enough that it would eat a bearing up.
