OEM Hood v Seibon TS Testing

theDreamer · 08-05-2013, 10:08 AM

I have an opportunity, before putting on a Seibon TS hood, to run some cipher logs and collect some data. I would like to do this for comparison for members looking for what results can or cannot be achieved when adding a vented hood to their car. Also looking for suggestions on what people want logged so everything can be covered.

My question is what specific units would you guys wanted recorded?
-Oil temp
-Water temp
-IAT
-Ambient temp (Can cipher do this one?)
-Others?

My plan is to get some solid logs in under different conditions.
-Traffic driving
-Hot temps, then idle for 5 minutes
-Morning commute (usually no traffic and temps in the 70-80)
-Others?

My car for testing:
-2009 6MT 370z with Stage 1 GTM SC
-CSF radiator & 25 row oil cooler
-Stock header & cats with F.I. exhaust
-Coupe front bumper
-No fender ventilation currently

That sounds about right. Make sure you test with AC on and off.

Hmmmm.

Coolant and Oil temps would be nice to know, I'm sure you'll see drops at speed just because of increased airflow.

What I'd really like to know is actual under-hood temps from various places in the engine bay.

For instance, on top of the intake manifold, in the Brake / Clutch MC area (how much heat soaks through the inner firewall into that compartment before and after), etc.

Hard to log those automatically without a dedicated setup though.

Yeah, maybe get a heat gun thing and when I run it up, stop really quick, pop the hood and measure temps? Not going to be perfectly accurate but might get close.

That works, I was thinking of those heat gun temp readers you can get at home improvement stores. You just shoot it at a target and it measures the temp, my father has one but he said it was cheap and only reads up to like 200ish degrees.

Yeah, i knew what you meant, was just offering a cheap solution that would actually datalog.

There are others sold by that same person that have multiple channels and don't really cost a lot more.

That's what I would do, get a 3 or 4 channel one and run those bitches all over my engine bay, then you can build an accurate model of before and after the hood.

Just use the car's reported ambient temp, subtract the ambient from whatever the under hood readings are and you'll have a (sloppily) normalized measure to compare before and after.

(since you're going to have your laptop doing Cipher anyway)

(also, you can log from the Rom Editor program as well if you have a Cipher cable, its logging capabilities are quite a bit better, IMO)

Might look into this, so it can log the data and I can download later?
It says on the page it just plugs in and reads out temps, so want to make sure I can run it under the hood & download at a later time.

I was reading this the other day, that Uprev is actually moving away from Cipher and saying to use the ROM editor for data logging now. Had not gotten to try it so will give it a test today.

It requires a laptop. It runs software on the laptop to record and save the data.

I figured it was acceptable since you're going to run ECU logging anyway. There are stand-alone units that are cheap as well, have to find them, gimmie a minute.

Yeah if you have a flashed ROM, use the ROM Editor, it's much better. It will give you a lot more detailed info on what's going on with the car.

Cipher works even with stock ECUs, so it still has its' purpose (and has those "gauges" it can do, which I have never used).

Ah, ok. Time to use the ROM editor from now on then for data logging.
Does it still save it out as a CSV file?

6 Point Temperature Indicator

Maybe something like this?
