I’m still excited to hear this beast roar again!!!! 😎 Test drive!!! Lets go!!Scott SainParticipantMay 8, 2020 at 4:53 pmPost count: 249
I keep going back to this in my head. Why 25 pounds? That is going to be over 500 hp. If you haven’t driven a 500 hp VW you’ll be in for a scary surprise. Engine life will be exponentially shortened. Just curious.
(For a reference, I keep mine around 12-16. And they are ridiculous fast.)PeteParticipantMay 8, 2020 at 5:07 pmPost count: 858
The real question is will it really need 25lbs/500hp to get on and off the trailer? 😉😀FranzKeymasterMay 15, 2020 at 8:48 pmPost count: 3358
I’m scared to drive it. Been up on the lift all week. Ready to do the glass install and exhaust fabrication.Scott SainParticipantMay 16, 2020 at 10:22 amPost count: 249FranzKeymasterMay 16, 2020 at 3:34 pmPost count: 3358
No adjustment on the waste gate…
I’m guessing that the cb gen4 fuel injection has a map or a limit for that in the software somewhere?FranzKeymasterMay 18, 2020 at 3:46 pmPost count: 3358
Made some air cleaner hardware this morning. Looks more “finished”. Stainless allen heads on top.

Yes you can go to the overboost settings. Cut timing when it reaches whatever level you choose. An electronic boost controller would be best. It’s very simple.FranzKeymasterMay 19, 2020 at 8:28 amPost count: 3358
Yep, Gen 4 has a boost controller. We hid it on the backside of the fan shroud.Scott SainParticipantMay 19, 2020 at 10:27 amPost count: 249

Yep. Mine is even smaller. But the same thing. I think mine is Ingersoll Rand? Probably still an air compressor controller. You can really smooth out how it works so you don’t feel the “on/off” surges. There’s a big boy word for that but I can’t spell it.dan.mastroParticipantMay 21, 2020 at 7:35 pmPost count: 8
I believe there is a 11-12 psi rated spring in the wastegate. Mark at CB said a boost of 11 or 12 is fine for the motor.dan.mastroParticipantMay 21, 2020 at 7:46 pmPost count: 8
Franz, the air cleaner hardware looks great! I would suggest calling Mark at CB to confirm boost, what controls it and if there are any combinations that are multiplying it, i.e. 12 pound wastegate spring + boost controller + software equals 25 or more boost. I am with Scott, boost of 25 is way too much.FranzKeymasterMay 28, 2020 at 9:16 amPost count: 3358
We’ll get her figured out. I’m going to work on finishing this machine next week.FranzKeymasterMay 28, 2020 at 9:18 amPost count: 3358
Titanium exhaust arrived from Ticon. Looking forward to fabrication.
Pie cuts ready to tack together into whatever bends I decide to make.
