Word of warning .
To get meaningful back to back virtual dynos you need :
A straight , flat (bump free) , safe , 1km section of road .
No tail or headwind.
You need the IATs to be within a few degrees .
You need the EGTs at the beginning of the run to be within 20-30 degrees .
You need to know the weight - don't change it between runs.
Best gear to do it in is 3rd for a turbo car
2nd might work ok for an NA .
If any of those things are askew ..... trying to compare runs is a total waste of time and will lead you to draw erroneous conclusions.
Also : anything other than a smooth curve (similar to a real dyno) can pretty much be ignored as a dud run . Anomalies abound when using this software and it can be really hard to get decent logs.

is it larger than stock? if so did you measure and can you share the ID?

I'm just sitting here waiting on you to decide to up the maf and shoot for 20psi

Was really hoping i would get enough headroom for safety in winter on my current setup - that's all. The weapon has a central tube within the maf . Looks like it might have an affect on how the maf reads.

LMAO blow it up?!?!?! Never would wish that on anyone. I just wanna be the little devil on your shoulder telling you it's ok to push for a little more...

yeah that was a kimmick thing to create a more power feeling when put on an N/A
I made drawings of maf adapter piece, you could have a machine shop make it and weld it to any size diameter tube you want.
I did this for my first build, I happen to have a second one waiting for a 3.75 or 4in intake tube. I was also thinking that maybe I could designe a entire unit for a 3d printer to make it out of abs plastic......
a long time ago I had a thread about it, guageing interest, I was gonna have 10 made but I only had maybe 1 person interested

Had a bad time yesterday with the setup after i cleaned the air filter . Went really rich.
Had me stumped for a while .
Till I disassembled the intake and found the tube that extends the intake (so the filter can sit outside the engine bay) , was on a slight angle to the maf tube . Hammered home to me how damn sensitive maf sensors are!

So ..... I think I finally figured out why my spoolup is not as good as it should be ....
12blade turbine with a clip vs BNR 11 blade
Load Vs RPM for 3 differently setup Greddy turbos
My 12 blade clipped turbine (sorry about the crap pic.)
BNR 11 blade with clip
(borrowed pic from 9ks' thread)

Yeah ..... not only are there more blades and much more daylight through the clipped turbine , but the design looks inferior as well .
It obviously works great for the lighter 57trim wheeel but with the 60-1 wheel it seems the extra torque require to spin it up does not suit the turbine .

oh yea...I saw the sticker price and wrote it off. To take full advantage of that setup i feel like a larger maf is warranted. POWA!!!

this is my first set up turbo..and that big turbo can fit down there, I believe that you can have some ideas what t ype of turbo you can put down there..the pic is just a reference for you guys

I'm still against fitting big turbos to the renesis ............... If you aren't going to go the whole hog and push for 400whp and do all the mods necessary to support that , a turbo "capable" of that is a really dumb choice. IMO
Mind you , the Precision setup i mentioned above might just change my views on that ..........
