HotRodGuy,

I spoke to Rob today. He is late as usual. He is now promising me the next phase will be done next week.

I told him I getting a little bit worried, however as long as it is completed by June 16, 2009 that I would bare with him. He assured me he would make the 16th.

All I can do is apologize for him at this point.

 

Hard to believe it's almost done. Can't wait to see the final build-out Chad!

 

*Good news ...... The stroker crank and rods clear the case by a couple mm's!
The crank has been ground to incorporate NASCAR Oval Bearings.





Splitting hairs! We have found the stroke limits on the case.

Tight fit!

 

The GT1 pump with one of a kind gears wasn't as lucky clearance wise.

Oh well .......... it clears now!

 

I just received the following e-mail today. I was not going to delay the completion past June 16th and the new larger liners didn't have a confirmed delivery date as of yet. If they could not arrive in time we were going to go with the 2 mm smaller ones. They will be arriving on time.

Hello Chad,

I can have the Liners to you by then. I am having these new Liners coated on the outside as well as the NSC on the bore faces. I have changed the top of the Liner detail making the Liner Top a lot stronger. I will need the housings back here to make a simple modification to them to fit these larger size Liners. Pistons will need to be matched, so let me know what you want done with these as I need to be involved to ensure all the sizes match.

Neil

 

I can't / don't believe it...i've been following this build since rennlist!



btw, what's so significant about June 16th?

 

My birthday and the day my best friend Mike Maring passed away. The rods were bent in February 2004 and I have decided to bring it to an end come hell or high water on that day.

 

Love the knife edging and the polishing on the crank,every little bit helps.Awesome setup!

 

Joe,

The motor has a lot little details. The crank was originally a 80.2 mm stroker. The NASCAR oval bearings are smaller and therefore we were able to take advantage of this by gaining 2 mm with the grind to make it a 82.4 mm stroke. The crank was also cross drilled to add oiling. On the oiling side the top of the rod big side also has two holes that squirt oil up on the rods and cylinder lining. The oil pump is a three index pump with roots type gears that pull a vacuum in the case.

The cams also have little details, they have a higher lift and duration , but they are also gun barreled out which reduces their weight by about one third.

The case has special front and rear seals to hold the vaccum along with being shuffle pinned and bow tailed. The bow tailing has the same basic idea as the knife edging.

Thanks for the kind words. I really can't wait to see your monster perform. I've been watching your progress with keen interest.

 

The project is moving full speed ahead. The pistons are being made and the the finishing touches on the rod dimensions are in progress.

What we are up against. The crank is 82.4 mm which is 6 mm more than stock. In essence this pushes the rods 3 mm further up the liners and heads. Sounds simple, we can move the wrist pins up the piston 3 mm, however what this does is increase the speed of the rods which isn't a good thing for longevity.

What we are going to do is move the wrist pins up the pistons by 3 mm. This will help increase the standard rod length 4 mm. In addition there is a gasket on the cylinders (not the head gasket). We will add a steel shim there and use two gaskets. This will give us another 3 mm with the additional gasket and steel shim. In addition our head gasket is thicker than stock which will give us another 1 mm. Add this to the 3 mm we will recover by raising the wrist pins and we gain a total of 7 mm and lose 3 mm with the strock for an overall gain of 4mm. This will allow us to increase the stock rod length by approx. 4 mm and keep the rod speed at a safe level. The only thing we have left to determine is if there is enough slack in the timing chain.

We will have all these parts ready to install by April 16th.

 

Has anyone else stroked or know of anyone who has stroked a 3.6L turbo?

 

Does anyone have a 3.6L tt motor that was stroked? Anyone know of a tuner/builder who is experienced with stroking these motors?

I can't seem to find much information from anyone?

 

I thought Todd K had something in the works for this?

 

I'll have to ask him.

99.9% of displacement increases are through increased liner and piston sizes. Up until recently those were accomplished with 102 mm liners/pistons which really were not 3.8's. Recently production of 104.4 mm liners and thus real 3.8's arrived. 4.0L were even harder to find and anything above 4.0L was extremely rare.

 

I know we have emailed one another back about a 4.1 liter kit?
