Raptor twin turbo initial final tuning #'s
 

Corey Henderson is in the final phase of tuning on my Raptor twin turbo system. First pulls were around 615 to 620 rwhp. Will post final numbers when available. Those folks going to the South Texas barbecue are welcome to check it out.

Those are some nice numbers! If you don"t mind me asking how much is just the turbo kit itself? I saw the regular lt1/4 kit was 5500-6500. Is it around the same price or is it more since we have a z? If you would rather keep to yourself I fully understand also. Looks like it sure will be a really fun car.

Since this is a prototype, I'm not sure what price will be from Raptor. I had my engine done and some other work that increased the cost. If I understand correctly, the system will be sold as a do it yourself kit.

Did Cory take over the Raptor project from Ron Hanselman? If I’m not mistaken Ron and Jerry (of Jerry’s Gaskets) started that company but then it disappeared. Just curious what if it’s the same thing.

It is still Jerry's Gaskets product. Ron Hanselman worked with project. Corey did alot of design work.

I think Corey fabricated a few systems as he built mine. You would need to contact Jerry's Gaskets to find out when they will be available. I'm not sure Corey has the installation manual finished.

What's the displacement and compression ratio?

Re: Raptor twin turbo initial final tuning #'s
 

Raptor is all mine now.

Jerry and I were partners some time ago however Jerry wanted to concentrate on Jerry's Gaskets and then sold me his share. He was really the one that enable the Raptor Turbo System to come to fruition...

Corey has all my systems to include Twin and Single Turbo variations. The Twin for designed for the LT5 and the Single for the LT1. I do believe that the Single will fit the LT5 but we've never fit one... They are all still mine.

And yes I've been silent for sometime as it was taking much longer to get Ron's car finished than Corey planned. He did make some adjustments to the design to make it fit more easily and subsequently changed the jigs.

If someone would like a system please PM me and we can discuss. Also, since I've been inactive with the systems so long, If anyone wants to purchase the entire inventory please PM me as well.

Cheers,
Ron H

364+ or- ci. 9:1 compression. Engine was put together by Henderson Performance with Lozano Brothers doing the machining. Corey put some larger injectors is because the engine was running lean at 7000 rpm. I think he said he also put in a different fuel pump to make there was enough fuel volume.
