Out of curiosity why are you putting in sleeves, always wondered that? Why not just forged coated pistons from Mahle that are 4032 alloy and using barrel shaped face rings which are gas nitrided? Then not have to mess with any kind of steel sleeves which could also end up being installed incorrectly if using a regular press and not a cnc press.

/\ Eventually the open deck block design is going to crack a cylinder wall. At what power, who knows. Better safe than sorry right?

Very nice.. Hope to see some numbers soon

In a 5.4L V8 that number is usually VERY high.

Don't get me wrong, the sicker the build...the better, but I'm sure he could hit 1000whp before that becomes a problem.

The sleeves will be installed by Darton themselves so that should take some of the risk of a faulty instal away. The sleeves will close in the top of the block adding more strength and rigidity. The sleeves will also help adding some extra displacement and most of all the door opens for extremely good piston/ring packages and as I'm sure you know if something was to happen its a easy fix then.

I think someone could hit 1000hp but it might be a one time thing. Rod bolts are the weak link and at that power level the block is going thru some punishment. On a true 150 shot I made 823hp and when we took it apart it looked perfect inside.

That looks like a very very complete package! Considering it's such a complete package, with a larger pulley to reduce boost this could potentialy be used on N/A engine with minimal additional parts. I hope might become available as a option at a later stage.

There are several things you must take into consideration for the na 55s. You will need bigger fuel pump. The na 55 runs on maf instead of map sensor. You will need to add the 55k pulleys including crank pulley. And the na 55 ecu will not be able to control the bypass valve. The you will need great exchanger and intercooler pump. Trans is weaker. there are ways around everything though. Rumor is Weistec will come out with an na 55 version

Off-topic, but you're better off sourcing a 2618 piston if available in a blower application. Not that a 4032 won't work, but the 2618 alloy will take more abuse especially on the street where some detonation is inevitable from time to time.

The designs have evolved to the point where the difference in thermal expansion between the two ( the primary reason for wanting the quieter 4032 alloy) is only .001-.0015

There are additional changes required, absolutely, but this in certainly the closest thing to a comprehensive hi performance solution since the HPS or Kleemann kits. The lower compressor outlet temps in conjuction with the minimal heat soak design intercooler would help make this the best option for N/A based engines. Still wont be cheap but quality never is.

+1!!!

Game changer for sure. Nice job.

PACougar

I'll believe it when I see it on one of our cars, and I mean a forum member. Don't get me wrong I want to see it! In fact I need one.

By looking at those pictures I see that the fuel rail in this kit is not LOOPED!? With so much potential is this a good thing???? Why did they design it like this???? We all know that the looped fuel rail is a MUST for safety.

Roverron

@vioillo looped is not necessary when the feed is changed plus the volume of the rail is increased drastically.

e55amgrocket

The ends of the fuel rails are plugged so it could be looped if needed but they look to be a lot larger already.

WOW , its finally here a BIG BAD *** supercharger replacement ,, I'm saving my money now ,,, now we have a real modding option. I can;t wait to see dyno numbers. Man its Christmas in Sept , Speedriven your next. Oh the price is not as bad as I thought . Go to a D3 cadiiliac site and look at their super charger up grades for V's 800hp + were in the same ball park.

GT-ER

Umm...no...it's not. I don't have a looped rail with nearly all the mods everyone else has and have yet to blow. As a matter of fact, I've logged timing retard at to 150mph and it doesn't even knock once.

Not only that, but weistec's rails are larger and their point of entry is like better distributed than the oem ones. Their rails are just fine.

vioilio

Thank you for the explanations and clarifications.

munich55

Wow looks great!
Something like an Y-snout with the air coming from both sides would be great :-)

betrezra

Or custom ram air hood like DAD's hood.

xpl0sive

will weistec include a tune in the kit? who else can tune for 650cc injectors?

Zod

its part of their package, they include it

Also have to say am am really impressed they did this!

biting my nails on this, but need to see results on a few moded cars first!

Also where is the HE core?
i do not see it in the websight pics ;/

blackbenzz

First post says it comes with a tune. Any competent tuner should be able to scale for injectors
