How much boost? |

It's.......right there
lol Looks great btw |
Love that torque curve, or should I say plateau.

That kraken mani magic and the 3" dp baybeee, Im so excited to get my stuff!
His new dps are made out of 2mm 316L SS. Serious shit. (Top pipe in picture compared to the old alloy on bottom) https://cimg8.ibsrv.net/gimg/www.mia...26d98901b9.jpg |

He updated within the past couple days. There are two dps in the pic, top one is slightly brighter metal, otherwise it looks the same from that angle.

added real dyno pulls from todays runs.

Sweet dude! I'm still waiting on Kraken parts.
Lets see videos! |
It's good, but a GT2860rs (disco potato) with a 0.86 rear housing can achieve that sheet.. just.

Dann 6258 not even sweating with 100 more hp to go. And it spools faster. |
No, I mean the whole graph, if that's your power graph you want a GT2860rs can do it at 18psi and have the same power at ~3000rpm.
If you're going to turn it up later, awesome. Dann |

100whp@3000rpm. Ie, same outright numbers, same low rpm torque.

Dann I measure turbos by how soon i can hit 200lbs tq. my 2560 hit it at 3250 my 6258 at 3300 my 2860 with begi manifold/dp at 3800. 2860 cant touch a 6258 spool wise, response, and max output wise. |
First let me say that its a sweet build and I am not shitting on you, I just wanted to let people who read the thread know that your graph can be achieved on a 2860rs.
Looking at your VD you have 100whp@3000rpm, just like a Gt2860rs can have. You have 180whp@4000rpm, just like a Gt2860rs can have. You have 250whp@5000rpm, just like a Gt2860rs can have. etc You can do it in ftlb if you want, but it's like for like comparing HP at the same rpm also, as i have done. You probably have a bit better transient response though. And i assume you will turn it up a lot further than a Gt2860rs can go, in the future. Dann |

GT2860RS, .86 housing, ~15psi. BEGi log mani, separated gas 2.5" DP down to a hacked up crush bent 3" straight pipe out the back.
I think I logged it, will post a log screen shot if I can find it. note: it was a dyno day so they were just doing pulls after pulls, the date, test/file name is incorrect. Attachment 228695 |
