Compound Turbo Setup Holset style

[viperlp01]

The cylinder itself is the issue, not the rings.

Very impressive to see what you've been doing, that's crazy!

Glad to see that my old block/crank will be put to good use too! I hope it does well for you!

I don't follow. Can you explain?

 

[viperlp01]

The heat builds up at the top of the cylinder. The rings will have the entire stroke plus an extra stroke to cool. Where all the heat is built up is the "biggest" issue. The cylinder itself during its heat cycles is trying to disperse its heat into the block fill and some into the water that is running through the center of the block. It is trying to expand. If you drive for an extended period of time the expansion can cause stress cracking. I am seriously not to worried about it. I am more relieved that the half fill will work so well from the information I gathered.

Going to be a nice motor, however most builders I know fill the block first and let it set with a torque plate on it for 5-7 days then surface the deck and machine the cylinders. I know thats what Patterson Racing does to all of their builds too. Have agree or disagree I'm just interested in another opinion.

 

[viperlp01]

I haven't filled the block yet. But it will be filled with the mains torqued and the torque plate torqued. I still have to get the ARP mains and do the 1/2 stud conversion. Just been busy with the holidays.

hell of a car man cant wait to see how it turns out with the new upgrades coming.

 

[viperlp01]

Filled the block this week. Still waiting on pistons but I got most of the stuff for the engine now minus cams.

1/2 stud conversion

BME rods FTMFW! His rods are head and shoulders above others IMO.

 

[ariman]

What is the cost of BME rods?

How did you pick your cams with two turbines to breathe through, if you don't mind my asking?

Hahaha well essentially I realize that I have a very larger turbine housing. The small one has a 60mm wastegate that directs(or releases) any back pressure into the big. I am going with the Kelford 294HL for this build.

Mine is the welded head. I got the valve jobs done today. It is much easier to set the tooling once for the intakes and another time for the exhausts. I spend 5 hours on the valve jobs today. 1mm over valves require quite a bit of de-shrouding so the tooling doesn't hit the aluminum too much.

Things are looking great John! Thanks for sharing your recipe with us all. Good luck with the rest of the build! Can't wait to see ya run at the Shootout again this year.

 

[viperlp01]

It will be in DSE again this year. We will be offering these engines to match our nasty head builds that we do. We sell what we run!

Should have some more updates soon. I really want to wait to hone the block until I can mic my pistons to verify PTW. Other than that I will have everything to put my short together and all I need is camshafts to finish the head.

No! Stay away from DSE!

Actually, good luck with the build man. Hopefully she runs smooth all season, can't wait to line up at the shootout.

 

[viperlp01]

Hahaha I hope so too. Taken every chance to bullet proof the engine.

 

[viperlp01]

Well I had time today to make a jig for the aluminum rod bearing locks.

Just wanted to snap another shot of the filled block

 

[bastarddsm]

Lol dse.....that belongs in q16....

 

[viperlp01]

Street car. Full exhaust, full interior, all glass, no nitrous, street tires.

 

[bastarddsm]

Low hanging fruit.

 

[viperlp01]

To be competitive in Q16 I would have to gut the car, carbon fiber hatch, no exhaust, ect. Just not me yet.

I'm setting the bar high. I don't hide my build from anyone. I am going to be running against Zimmer, Bowers, ect. Shoot Zimmer has went 9.50.

 

[viperlp01]

Checked block clearance on the rods today. Fit perfect with no issues!
