But think how much more attention you could bring to the car with a sequential trans.

Speaking of big dollar parts...I don't think I ever posted this. This intake was designed and 3D printed. It cost $10,000. I think they took an interesting approach to the exterior look. lol

This intake is for use on a BBI built car that should make 1300 hp or so to the tires. This car build is meant to be a streetcar to replace his 1738whp car that went 219 mph in the 1/2 mile.

straight cut gears in any transmission will sound like that. Cars like the first gen Camaro had an option for a M22 muncie that had gears that were more straight than the gears in the M20 & M21. Although not a straight cut gear, like a spur gear, they reduced heat and were stronger. But definitely made more noise than the gear sets with more angle.




A video to hear an M22 in action

Are you looking to buy new? I think @03cobraski is looking to get rid of his.

Not looking just yet, all money is going to go into the body work shit this winter first... Then I'll finish buying parts for it.

$10K holy shit, that looks wicked though!

I thought maybe the process of 3D printing metal was the reason for the look, but after watching a video on 3D printing metal I quickly realized that it is probably not the case.

Ya, you can see the inside walls of the intake and see they are smooth. It was probably done to save money on programming time or to give it a "crude" CAD drawing look.

The sad part is, once it is in the car you can't see it very well at all. Which sucks. lol

So short answer, no. lol I had some small issues since the car got back together. The first being two issues with one of the rebuilt turbos. They clocked the Variable Geometry Turbine ring slightly different than stock. And had a wrong stud for the turbine to CHA housing retention. It would not have been an issue if the VTG ring was like stock. But because it wasn't, the arm from the VTG to the turbos electric actuator for the VTG ring was getting hung up. I filed down the stud and that fixed that. Then I had to have Porsche do a position re-learn for the actuator. That took me almost two weeks to get the car in for a 20 minute program. lol

Then I noticed at idle the short term fuel trims were way high. So I figured I had a vacuum leak or fuel pressure issues. With as tight as it is in the engine bay I was really not looking forward to fixing that. But Eric quickly found the vacuum/pressure line to the fuel pressure regulator was pulled out of the hose connection. So I had to fix that with only enough for one hand in there. haha It wasn't horrible. Removing the airbox and whatnot gave me enough room to get it fixed. That surprisingly only took me a half hour start to finish.


We are on revision number 4 on the 93 octane tune. The tuner said this version has all his stage 4 tricks in it. It feels smooth and very strong. We should have one or two more revisions and should be able to move on to the E85 tune process.

The data logs are fun to look at. Even when we had those real hot and humid days last week, the intercoolers were working well. We are doing 3rd gear logs from 3k to 7k rpm. With 22.5 pounds of boost, the AIT only raises about 4-6 degrees on two back to back runs. In the cooler evenings this week they have stayed at the same temp throughout the pass. lmao Definitely worth the money there! Garret cores FTW.

It is always crazy how much bigger/better intercoolers help things along woth good ducting. I went from stock to the massive smic on my Z and it felt like I was driving in 60 degree charge air all the time. A very noticeable upgrade.

Oh no doubt. Everything has larger diameter tubing, larger openings, and has smoother transitions. From the turbo inlets, the cold side hoses, y-pipe, and intercoolers. It all adds up. There is a slight trade-off in boost response with the larger volume of it all. But something you could probably ever really feel, only see in a data log. The gains in the air flow and efficiency you can feel for sure.

So Sam said we are done with logs for the 93 octane tunes. He said he made a couple small adjustments for the final map.

He put the last data log into a virtual dyno. He guessed a little low on the cars & my weights. Steel rotors versus carbon rotors, me being a stick figure, and so on. So he said it is probably another 10 hp/tq more. But probably pretty close to what it would make on a 4wheel dyno. Typically a full bolt-on 997.1 Turbo on E85 makes about 590-610 hp. I'm am really happy as we are a little above that on 93 and it is a crisp and safe tune.

Now on to the e85 tune and another 100 hp or so. Oh yeah!

also, I did a couple of logs on revision 2 where I did a 3-4 shift. In third gear and starting WOT at 3,000 rpm the boost is 20 psi at 4200 and tapers up to a peak of 22.6 psi at 5,900. Then carries the 22.6 psi until I shift at 7,000. In 4th it is still at 20 psi and tapers back up just like it did in 3rd gear. So there is virtually no boost drop on the shifts. And these are not super fast shifts either. So that is awesome as well. Probably a big advantage with the VTG turbos.

How do I strap my car down to said "virtual dyno"? lol

Can I use hopes and dreams to make 1k Vwhp???

Download the virtual dyno, do a data log, enter some info, and get the dyno graph.

It is actually a pretty good program that has been proven to be pretty accurate if you enter the required data correctly. Like car weight, tire diameter, yadda, yadda, yadda.

But like a real engine or chassis dyno, it's just a tool for comparisons of changes you make. Or campfire bragging rights. lol

@Jeffs FRC Here is a good example of why that program is nice. This guy has overlays of the progression of his car. Stock turbos with 93, then E85. Switched to the 63.5mm turbos on 93 and later with E85. Nice to see the different power and curves without having to rent a dyno every time to get a dyno graph.

Virtual dyno can be pretty accurate, but it really depends on the road. A nice flat/smooth road and you are pretty accurate. I used it for my Focus ST.

What company did your turbos ? How much are you seeing over ambient temp by end of like 40-140mph pull .I have oversized Garret core for my power but I won't have to mess with it if I decide to make more power. Its a 28 x 18 x 4.5 core with 3 inch short route piping . it was like 100* at nfz 1/2 mile , I was seing 112-113* end of the run .My friends CTSV was getting close to 190*

Exactly. It's no different than a chassis dyno using a calculation to figure out the power.

I have a couple flat roads where I do my logs. Which is convenient.

TiAl Sport is the company that upgrades the compressor wheel, clips the turbine wheel, and rebuilds them.

I have not made a run like that yet. Maybe I'll get a chance to make a few passes like that this weekend. My buddy that was working on the car with me has a full bolt on, stock turbo, 911 that has the same AMS intercoolers. At the autobahn he saw like 10-15 degrees over ambient for the whole session.

Sounds like the intercoolers you have are working great too. Those cars like the CTS-V, 03/03 cobra, GT500, Hellcat, and so on, all have issues with heat. Most turbo cars coups stand to get a nice upgrade as well. As we see with the upgraded cores we have. But it sounds like you are all set for those upgraded turbos this winter. lol
