IPS Twin Tubo on its way

You and me both.

The LSA heads I ordered are being ported by Richard at WCCH and should be ready in a couple days. I ordered them with Inconel exhaust valves and stainless intake valves. They are made from a better aluminum and are rotocast. They come standard on the supercharged 6.2L Cadillac CTS-V. No one had cut one open yet to see if they have a thicker deck or not.

Here is what GM says about these heads:


"The LSA heads feature a unique "wing'' cast into each intake port to promote a swirling motion that blends the pressurized air-fuel charge. The heads are also cast from a premium A356-T6 alloy, which better manages the heat generated in a supercharged engine. A356-T6 pays particular dividends in the thin bridge area between the intake and exhaust valves, where effective heat dissipation is crucial to both performance and long-term durability. Finally, the LSA heads are rotacast. This process rotates the head mold as the molten alloy cools and essentially eliminates porosity, or microscopic pockets of air trapped in the casting. Rotacasting delivers a stronger part that helps maintain performance and structural integrity over the life of the engine.(The heads are nearly identical between the LS9 and LSA)
Valves are among the most heat-stressed parts in an engine, and their wear resistance is crucial to long-term durability. Those in the LSA are manufactured from a high-chromium steel alloy called SilChrome 1 (The only difference between the LSA's exhaust valves, and the LS9s is that the LS9's are filled with sodium for the extra heat protection -- the LS9s intake valves are made of titanium.), with thicker heads than most other Gen IV V-8s. They promote heat transfer away from the valve face and valve guide to the cooler end of the stem, where it more readily dissipates. This maintains a lower, more uniform valve temperature, reducing wear on the valve guide for better alignment and a consistent seal between the valve seat and valve face over the life of the engine. The intake valves measure 55 mm in diameter and the exhaust valves, 44 mm.

Cool, i'm working on new upgraded engine as well. First i was going with GM lsx block, but sold it and ordered RHS aluminum block. Will go with lsx 6 bolt heads. Ti Intakes, sodium filled exhaust valves.

any price range? more info on the kit? turbo sizes?

Generally speaking the sodium filled valves are not ideal for high horsepower applications, they tend to be weak, albeit they deal well with heat. I would look into inconel one piece coated exhaust valves with a solid stem and bronze guides to help with any increase in heat.

Brandon,
I will look in to this. We are using ti sodium filled DLC coated exhaust in our 1450+hp 10500rpm 500cid N/A engines, but only put about 50-70 runs + dyno on them before replacing. Inconel solid stem is probably good idea, since weight is not that big issue here.

That should be a fun build

Exactly, everything is purpose designed

Good use of DLC, more and more coatings offer the best benefit for strength and durability.

Thought I would bump this thread for an update.


I got the kit at the beginning of June and started the install about two weeks ago. Have been dealing with a lot of little problems but should get it all buttoned up this week.

I have had some issues but they are pretty much resolved now.


Here are a couple teaser pics.














I have to upload more pictures from the camera to the PC then I will post them up.

WOW... thats a lot of turbos and Nitro..

Only two turbos and one nitrous bottle are for this build the others are for other builds.

Here are some more pics.






I went and bought the lines I needed and should be done tomorrow.

Looks good, love all the Turbo's.

[SRT10KLLR]

Here are some of the lines I had made. I can now finish up wit the install.

Looking good J....
