So the meeting yesterday went well IMO and a lot of things were covered. Engineering looked over the manifold that I brought and was impressed with some of the engineering/design which made me somewhat happy. They were NOT impressed with the machining quality which goes without saying actually. Then I proposed some of the tweaks I was wanting to make/thought of doing. That for the most part went OK and a lot of questions were asked, but there was a couple concerns pertaining to runners and that would require a bit more engineering/flow testing and of course costs. All and all they seemed that it would be doable, but they may have to reach out to another company on some issues and they will be getting back to me so we can discuss all this again. I'm also toying with the idea if this all works out on doing VERY custom units specifically geared towards someones specific engine build that they might be doing ie... Custom size ports to match your heads specifically. Have a great day all.

Just a little update on the manifold tooling. I got a call today from the pattern maker that the tooling is done and ready for pick-up. 
They say it is as good as new now and ready to start pouring castings once again reliably. Now, I need to go to the foundry and see what I can work out with them if anything. More as this story as it develops. Now if I can only get this virus thing to stop. Ugh! 
I should be able to pick up the tooling next week.

@Buccaneer thanks for the update, and maybe more importantly, your dedication to this project. I'm looking forward to hearing from you again.

UPDATE: I picked up the Renegade tooling today from the pattern maker. It all looks nice and just like brand new again and ready for pouring. On to the next step...
On to the next step...

UPDATE: I will be going to the foundry in the morning with the tooling to see if I can get them to do some pours at a reasonable price.

UPDATE: I talked with the foundry today and they looked over the tooling. At least they were receptive to doing the test pour, but at what price? I dropped the tooling off with them and agreed to do three test pours with a follow on of 10 units if everything like the machining to include the price was good. So, I will have three units for sale if the pours go OK, but that would still be at least three to four weeks out. The foundry is supposed to call me tomorrow with a quote and hoping that they don't get stupid on the pricing. More as this evolves, but at least it so far it looks promising and going in the right direction.
Called my machinist today as well and had a chat about a game plan for the machining and some changes I wanted to make to the manifold. He said when the pours are ready we can discuss what changes he thinks need to be made as well to produce a quality unit. He did laugh a little and said... "this isn't Eddy Motorsports and I don't let junk go out the door"! So, everyone that is interested, hang on a bit more and we'll see how this pans out. I'm going as fast as possible and want everything right the first time on this project.

@Buccaneer Thank you for the updates and for working so hard on this. I'm honestly surprised how fast you're able to move this thing along given the current situation.
take whatever time you need. My car is broke anyway lol.

Man there is a lot of easy power to unlock on these engines with this intake. Mine dynos at 270HP on the rear wheels with a Renegade, head and cam. That a bit over 320HP at the flywheel assuming 16% loss through the 4+3. From the factory these cars were rated at 205HP.

Thanks all. We are about 90% there, just need to see what the foundry comes up with in the way of a price and I'm still crossing my fingers on this. When I arrived at the foundry they didnt look all that busy, but who knows. Maybe that will work in my favor. Once the pours are good, we ARE A GO! I have no concerns on the machining end of things. All in good time on the progress and considering what's going on in the world, things are going well actually. Keep watching for news on this project.
Now this is funny...cheater.

I'm just gonna tell people my wheel power is my crank power.

1. My box stock '92 LT1 did 279 RWHP, on two different dynos on different days. We know that the LT1 is 300 CHP, and therefore that is ~ a 7% loss
2. My box stock LS2/C6 did 366 RWHP. We know that the LS2 in the C6 is 400 CHP, and therefore that is ~ a 8.5% loss through the drive train.
3. My '89 'Vette Kart is box stock other than dual exhaust and no air filter. I did 240 RWHP. Is the Kart making ~280hp (240rwhp*16%) with only exhaust and no air filter? I doubt it.
No....the claims made using 15%, 16%, 17% on stick shift cars is pretty wishful thinking, in my experience. I'd wager that you're closer to ~290chp...which is pretty darn good for a CFI.

I've said it many-a-time on these here forums: 16% is QUITE a generous assumption. Quite generous. How can I say that?

But again, that's why I'm saying my wheel number is my crank number.
