N20 map sensor to use with RBs, is it really worth it?

FRMTL2_335i · 04-23-2014, 08:17 AM

hello guys im trying to get to together the last pieces to do my RB swap, just wondering if who is running the n20 map sensor and if its really worth getting it, also where did you get it from? i know the 2.5bar stock sensor is good for 20.75psi, and i have not seen many people if any run over 20 psi on vargas.

I will be running full e85 and meth by the way.

i don't think its really worth it. your going to kill them a lot faster just to gain 1-2 psi more and it might just be a spike in boost. if you don't care about having a kill tune, do it ! I've seen people around here push a little north of 500whp at 21psi

X2

You really only need the n20 sensa if you are gonna be consistently running 22 or more psi

Bought one - waste of money.

The N54 TMAP sensor is rated at 2.5bar however sensor saturation occurs below this point. I would recommend using the N20 sensor anytime above 19psi.

What psi do u run? Map? Can u post a log for me?

I'm trying to hit at least 500whp 500wtq with my set up

FRMTL2_335i · 04-24-2014, 08:52 AM

Also what psi are RBs really worth having it set at? I've seen ppl pushing 22psi, but is that any efficient at all at that point?

I'm no expert but i did have a set. I wouldn't go any higher than that not that the RBs can't take it but you'll be pushing for them negligible gains on a stock motor.

Not trying to thread jack but Just that you are able to run 100% E85 with the 455, hows that going?

shmorgan77 · 04-24-2014, 09:22 AM

The map sensor is worth it, it's a bmw part and if your going to run north of 21psi then you have to. Totally worth the 100 bucks for 50+ hp/torque

But thats not suppose to be done, lol how are your logs?

robc1976 · 04-24-2014, 07:18 PM

Love mine, you can also have a higher meth additive via the jb4 with the N20

logs are just fine, i ran it on either map 2 or 5, mostly 5, i tested the e85 regularly, it never went below ~81%
