I agree, looks so good in there... Are you going to run open trumpets or got a plan for something else?

I'll have trumpets with sock filters. I know I could get a couple more horsepower with an enclosed box... but there will be enough power already and I like the induction noise.
Unfortunately, I don't think it'll be ready for SoCalVintage..... ughLast edited by AceAndrew777; 08-23-2022, 03:03 PM.Comment

Curious to know how the tube from the crank case sits into those ITBs? Or is it possible to block off that passage. I have the RHD set and it's most just set in place but not extremely snug.

Wow the engine looks right at home!
Nice choice on valve cover paint, compliments the chassis nicely.

Similar to stock and RHD, sprung loaded into position. It feels pretty snug, but I could run a stiffer spring as well.
I loaded up the titanium tubing into a box and Andrew (IE) was kind enough to stop by during finals week to tow the car up to Drago's shop.
It's absolutely crazy how light the titanium is. I can hold the exhaust system with my pinky.

Drago and I wanted to do something interesting for the headers to go along with the goal of having a higher pitch sound. To coax out the higher frequencies there are some generous loops, we also added a crossover (not enough room for a true 6-into-1, and lastly a fairly sharp bend at the bottom. Hopefully it works, but given it's an experiment there's always the chance it'll flop! While the car was there, he ended up using it as the basis for some new Koogleworks offerings. Love this community.

(don't mind the scrap red valve cover), ended up looking like some of the hakosuka headers!

Once it was wrapped up, we rolled the car up the street to IE. Fun to see it back on the lift where I did the initial tear down in 2016!

Omg pleeease teach me and tell me where I would learn the most about how to achieve a higher pitched exhaust system! I've always wanted to learn this. The resources I've looked at usually don't get that specific. Or it goes crazy into math. How did you learn about exhaust design to get the results to want?Comment

This reminds me of a video I saw about a stock car with a high pitched wail at Daytona. The Morgan-McClure 1995 Chevy with a unique crossover pipe configuration. Actually pretty interesting for a motor nerd like me......

It's a mix of art and science ... so it could backfire!
As described to me by one of the guys who helped...it's a sound wave, so the shorter the wave, the higher the pitch. Picture physical components that would encourage that shorter wave while discouraging the longer wave. I told him it couldn't be that easy .... but the guy has his physics doctorate and designs satellite wave guides, so who am I to argue. I did do some math, but frankly I couldn't find anything that would help simulate all of the variables... more time/money than my paygrade.
Generalities:
1) longer looping primaries (you can see a similarity between this header and that of the Ferrari 412 T2 3.0L V12).
2) cross over and/or collector as close to the end of the primaries as possible.
3) sharp bend close after the collector.
EDIT: Latefan, the Volvo and square tail 02 are two of Drago's cars. He has big plans, but time is an issue. Love the Nascar crossover video. Here's the sound of that Ferrari 412 T2... https://www.youtube.com/watch?v=5SoZiTxdQyw&t=62s
EDIT: Simon, ok. Let's talk a little more soon. I have some friends in Paso Robles, and we were thinking of staying there, then driving the fun road to Monterey.Last edited by AceAndrew777; 01-31-2023, 12:32 PM.Comment

That 412 is crazy - like a wail with a shriek above it.
I always think of great engines as musical instruments - after all, all they do is move air though. The combustion and the exhaust valve opening is the buzzing of the trumpet players lips, then the rest is plumbing, length, resonance, pitch, materials, tone, etc. What a trumpet can't do is that fantastic intake wail of good engines. (maybe that's the guy breathing in...??)Comment

sheesh I've been away from r3v for too long. Seems there've been some good updates I'm missing. I'll have to check back when I can see the photos. Currently on a plane with wifi that blocks many media sites.
andrew congrats on the note about working on james webb, I've been mind blown over the images coming out. it's so inspirational. happy to see progress here. can't wait to see this in person some day soon!!Comment
