home-made boost gauge
On my search for a low yet accurate boost gauge suited to the Stillen SC kit, which didn't get far, I got the idea of actually making one instead.
Most Gauge go at least to 25 or 30 psi. What we want is no more than 10 psi. And the accuracies of mechanical and electronic gauge are beyond scrutiny. We can but hope that 8psi doesn't actually mean 7 or 9psi. So I was thinking of getting a suitable BOSCH MAP sensor, they are highly accurate (OEM parts) and very fast response time and have a very linear output across their range. All we gotta do is display that output as eg. LED bar or digits. It just needs a little voltage conversion to express that output voltage in numbers representing psi. Electronics wise this is very simple. The display possibilities would be endless too. Saw this inspiration for a BMW: The challenge is finding a cost effective BOSCH sensor with calibration curve available. I looked at this cheap fella #0 261 230 191 (used in supercharged Mercedes and others) with a pressure range of 0.15-2.6 bar (up to 23psi boost) but no datasheet. Whereas the #0 281 002 119 (up to 22psi) has a datasheet saying response time is smaller that 10ms and accuracy is ±1.5 kPa, that is ±0.2psi guaranteed accuracy! But this particular part is pricey. I keep searching, maybe I get lucky |

The Stillen SC kit seems like an addition I'd love to install on my Z. For those of you that have this Stillen SC kit, what would you advise I'd do to my "stock" engine along with this upgrade.
Thanks! |

The Stillen SC kit is specifically designed to bolt onto a stock 370Z/G37.
But recommended add-ons are a 2.5" catback and an external engine oil cooler. A boost gauge and A/F wideband gauge are optional additions, too. You don't need to make any other preparations. Stillen advises against headers or downpipe/cat upgrades. I am gonna get my SC kit early next year, that's the plan anyway |

A larger heat exchanger is always helpful. I'd put an upgraded radiator on any boosted Z. And you really need a custom tune. The canned one leaves a lot to be desired.

I drove to the track and before I left pit lane the car thru a service engine light I put on a scanner and it said lean bank 1and 2 We cleared the code and I tried going for session 2 and 2 laps in the light came on again and car started to backfire and no power We cleared the code again and I just drove it home Cars idle is erratic still and while driving now sometimes surges ,what sucks is i told you guys about it and I feel like I wasted time and money today for nothing I'm seriously thinking of putting the car back to stock You guys kept all my old stuff injectors, pump ,etc.. So it shouldn't be a problem

If you mod it to make more power( You should make 410-415WHP) then be prepared to buy a motor, Seems like any of us that chase more power with this kit fail. I chase 500whp got 457 and BOOM but with the info on the feed line from Chris I think??? I know why mine popped, and might be why the others have went to , Guys are popping CYL2 or 3( I did 3)

Here is a log report from codes

zmanelite, you should not be driving the car!
let it get looked at by an experienced tuner, looks like there is something wrong with either your map or fuel supply. If it is throwing lean codes, it is definitely way to lean for forced induction as for the P0106 MAP range problem, tell your tuner to disable the DTC in your map file (this is normal, the MAP sensor is not supposed to see positive pressure, as it is an N/A vehicle after all) Quote:
As for downpipe/cat upgrades, i read a lot about that and most people will tell you that downpipes/cats or TPs will decrease boost on the stock pulleys/impellers. I have just installed this kit, i am running stock headers, berk HFCs, Motordyne XYZ Pipe and Tanabe Exhaust, so pretty much everything except for headers. I am seeing 8psi on the dyno and 9psi on the road, so i consider this to be a myth. Last edited by niko86; 10-19-2014 at 02:51 PM. |

I had this ONCE: P0106: Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance Problem I reset the code and had my tuner tune the range of the MAP sensor to a higher threshold. At least what he told me ,I never can back on again. I would look at that for an option. That also may tie to your lean code NO?
