New MAF options coming for Chrome?

**Ange** · 06-25-2016, 03:25 AM

some first tings to check when running lean

*check inlets between mas and turbos for leaks. If leak between there then you're pulling unmetered air

*check fuel pressure (hope you have a gauge!)

Any news regarding the Jester MAF?

Well yes and no. My car is waiting at the tuning shop and is currently scheduled for a dyno tune sometime on Weds.

Here is the Dyno sheet. 407awhp, 403ft lbs.

So this is a solid 48awhp gain from the 359awhp the car did with the 482 maf.

At 17lbs the car did 379awhp with the 482 MAF so this is a solid 48awhp on my setup!

What snails?

Sorry edited previous posts above... it was 48awhp gain not 28awhp. Using Boostmore 15g turbos with the standard wheel.

This gain with all other parts except maf being the same from run to run?

Gain seems a bit too much. From all I've read evo maf is not a limitation at those hp levels..

They're literally a combo of a stock 3/S MAF housing with EVO MAF internals. It's been tested to make well over 450hp so far but no one seems to have a car capable of making any more power than that. That's why we haven't really been advertising it. It hasn't been tested on a car making any real power.

Interesting.

I have done a bunch of work understanding how the MAF plays with the AEM EMS http://farnorthracing.com/stealth/AEM_Mitsu_MAF.html and I've been laying the groundwork for conversion to speed/density via locating a combo MAP/AIT sensor on the manifold http://farnorthracing.com/stealth/MAP_sensor2.html

But the MAF is really soooo easy to program.

Has anybody ever dropped one of these things on a flowbench and measured CFM cs MAF freq directly?

We don't have any specific evidence that the new MAF instantly delivered the extra HP. It was not a comparison dyno only session. This was a tuning session with the new Jester MAF installed.
There are likely other factors at play here that contribute to the gains. Not the least of which is the runs (as seen in the dyno sheets) did NOT occur on the same day.
I would suggest that this is comparison has some room for error when looking at just the new MAF. But what the data does tell us is that the MAF is a good choice for standard 15g turbos (vs say a MAF-T and GM MAF setup) and not a limiting factor in HP at this level (which we expected).
