OH yeah, NOPR video'd the Dyno session on the first two pulls, so check back tonight for that, and the dyno chart. |

here is a pic of the dyno graphs, two runs one is smoother up top than the other, both are cutting out bad past 7500rpms, I think it is the fuel pump, which is stock, so I put in a walbro and will test again tonight.

Yeah, it's got a hemi.
|
Hey shm, check back at my post I added the other dyno run, and blury numbers
|
is it 6000 or 8000 for peak horsepower on the 310 hp run?
|
It is 8000rpms, only because after retarding the timming and adding fuel it somehow surged the torque for a quick second at the end of the run, you can see the torque come up a little at 8000rpms, but still much below 216 lb-ft

I have a video, putfile hates me. can anyone host this?
|
awesome setup man. car sounds mean as hell.
|
Okay i got the video ready. It's hard to read the numbers on the computer in this small, low quality version, but luckily someone posted crystal clear pictures of the print out.. oh, wait...

congrats on the projtec...i love how it idles...but i still prfer a strong V8..again though, good luck, and i hope u prove the greatness of rotor motors :bigthumb:

These #'s are still without the semi-p port manifold, right? If so, the motor has MORE hp up top!

On your future run could you start earlier in the rpm range? I would like to see the torque output in that range when compared to the stock intake which has longer runners. The dyno sheet below is of an unopened stock block 20b NA with stock LIM & UIM. |

Hey! Read your inbox!
I hope you'll come out to our drift event September 4th at Kil-Kare Dayton. I would love to ride! |
Wow, nice dyno #'s. Can't wait to see them with the PPorts opened up. Just out of morbid curiosity, but has anyone tried making the intake maniforld out of carbon fiber or vacuum formed plastic? I only ask because I notice that stock the intake (and associated air) gets blasted hot on the FC, so I can only assume that it would be substantially more on the 20B. Also, why aren't your headers wrapped and ceramic coated??? :nono:

I was afraid to heat wrap the headers, have you personally tried this? I have heard of stories where people shatter the headers from too much heat, was wondering if this was true. My headers are made out of 321 stainless, if that helps.

Good to know, i will be wrapping them very soon!!
|
Hi there. Can you give us a little info on the inlet manifold? e.g who cast it, is it avaiable off the shelf etc.
Excellent work!! |
I'm going to guess the intake is custom built from two 4-port sidedraft intakes. One mounts up stock and the other is cut in half. Atleast thats what it looks like to me.
