Glad to see it up and running! Always a good feeling. Any road test yet?

So it has some piston slap going on at cold start? Do you know what your piston to wall clearance is? Also, what alloy are the pistons made out of?

@iNewton

I would still be worried about the balance. Its not all about overall weight. On the rods you have a big end and a little end weight. The Eagle rods weigh more on the big end then a factory rod. See attached picture. This one was ground down to get the big end weight down to what a factory rod is.

As for your piston, if they do not have an offset pin, that explains why your rod hit. I have only used offset pin pistons in my builds. Helps keep skirt wear down.

@iNewton Here is a picture of the LE5 I am doing right now. Same Eagle rods but JE Pistons. This on has about a credit card thickness gap. The only difference I can see to make yours hit is if the wrist pin offset different. Do you know whether yours are offset or centered? If they are offset, do you know by how much? Also, I know you said you were not pulling the engine. If so, did you balance the rotating assembly?

Springs are the ZZP 82#. They are the only ones that fit with no machine work. I have not seen an issues with them rubbing on the head even though they are very close. I am running some Patriot springs on my 2.2 and they are even smaller. Bad news is that you can't get them any more. They are a dual spring as well.

No stretch gauge for the rod bolts. I hope you have the ARP-2000 bolts in yours (stamped on the head of the bolt). If not, I would get a set. Just TQ them to I believe 43 ft lbs, let them sit over over night and TQ again. Be sure to TQ in 2 steps as well. First pass to 30, 2nd to 43.

You are correct. Those are 2.2 rods. I like them better because they are longer and that helps rod angles. The pistons have to use what they call ring savers due to the wrist pin being up in the oil control ring. This is due to the longer rod. No bad side effects though. Most V8 stroker engines have the same thing.

Yes the valve train was slightly upgraded. Just a good set of springs and titanium retainers.

If Noel gives the approval, I have plenty more pictures I can post of the build. I also have part numbers and all specs on it. But I don't want to ruin anything if he doesn't want people to know.

I can say, the pistons are all custom. They were not the most fun to design. The biggest problem was getting rings. For some reason the bore size on 2.4s is not common when it comes it rings. So the bore size ended up a bit odd. Its all the little things you got to check before hand when designing a build that makes them fun!

Good work, only I find it sad that no information of pics about engine building is posted...

Wish vendors who actually have this experience and knowledge would show more than wastegate spring swaps...

What would you like to know about it? Like what is on the inside? Maybe, just maybe, this....

Lets hope this goes good! I know all about this engine and what is inside it. I might have had just a little to do with it (if this is the same one I am thinking of). Hoping to see some 400+whp pulls!

Nothing but bad news there. Hope for the best Noel! On the brighter side, looks like it is a great time to expand!

Worked perfectly! Thanks. And yes looks like a lot of people joined this past week compared to a few weeks ago.

You guys aren't kidding. They are getting bashed over there!

Mods - Did you guys notice a large increase in new members this week over the previous weeks?

Ya I know... saw that one coming. Waiting for @Tripod to make me a new avatar cause of it

What kind of boost is each stage seeing? Also, is this on pump gas or was something like meth added?

If only there was a little more room in the Slingshots you could have a roots....

I have seen that intake. It is a piece of art. But...

For about the same price you can get a blower.... First twin charged slingshot... Kill 2 birds with one stone

I agree with that. Better then what was on there before! I like the idea of an aftermarket intake best though.

I was talking about getting rid of the banjo completely, if possible. That way there is only one spot that it could possibly leak (where the fitting threads in to the intake). Right now you have 3 possible spots for it to leak. Not saying it will, just saying that there is more of a possibility. It is kinda ugly too haha, but good thing you wont see it!

I made it over from the darkside! Thought you would like to know.

Anyways, why use the banjo and brass fitting? Seems easier to me to just tap the inside of it to a 1/4" or 3/8" NPT and run a 90° fitting. Less connections, less of a chance for leaks. That would also leave you the option of running a "T" out of it if you wanted to connect more then one thing to it. Just my opinion though...
