I’m in the process of reverse engineering the Hellion setup. I can tell you that I’m going to be running a 66mm T4 flange pair of snails. I’ll also be using the Turbo Smart EBoost2 boost controller. All said and done I’m quite sure I’ll be able to build my setup for around 2k as opposed to the 8k starting point that Hellion offers the kit at. I’m planning on using the same Waste Gates, & BOV as well which are the most expensive part of the build. Piping is fairly cheap and I do my own welding so no out side cost to fabricators. With that being said the Hellion kit is very well built and worth the money. I just someone who knows how to fabricate and thus not willing to pay for other folks engineering. 6-8 psi should net you your desired results if you have the supporting mods to for boost.

If your just looking for 600hp why not just spray it? Its the cheapest route to go to get to the hp # your after.
Spraying is only cheap if you don’t plan on using it that often. As someone who has sprayed for the last 2 yrs I can assure you it isn’t cheap. At nearly $400 a track outing.

The TT Hellion kit will get you to 600hp with their 5psi spring and obviously keep your Shaker. The temptation of switching springs for more boost would be very tough to ignore and smoke your engine.

You could also go with the Magnuson from Steve White that will keep your Shaker with their optional bracket. For a centrifigul choice you could go with either the Procharger or even the new kit from Vortech which will get you to where you want.

I know how I am and I know that I won't want to spend a ton of money and only use 5 or 6psi so If I do decide to go with boost I think I would want to get a forged short block so you can use the boost that the kits are capable of.

Either way let us know it seems like a ton of people boost their 6.4's but we don't get a ton of long term results while keeping the motor stock. Just about everyone ends up putting a forged short block in there which goes back to my opinion that it would be tough to spend that much money and leaving the psi so low.
You are absolutely correct. Take a look at my build thread, I have a comparison of the stock piston skirt and a forged piston skirt. Once you see how short the stock piston skirt is you will understand why any boosted 6.4 needs custom forged slugs.
