I just wrote up a quick article on my site about some dyno action last night…
The Car: S13 with SR20DET. STOCK turbo, STOCK injectors, STOCK MAF.
The Test: Run the car exactly how it showed up at the shop. The owner had installed a manual boost controller and was running at about 10.5-11psi of boost pressure. Then, install and tune a plug-and-play AEM EMS.
The Goal: To maximaze the potential of the SR20DET motor while still maintaining its reliability, drivabilty and ultimately improving its gas mileage.
wow… that’s pretty freakin’ cool… stock sr, turbo, injectors, maf and you got to 248rwhp at 13psi? that’s so awesome… i’m curious as well… this was a s13 SR?
Would powerfc yield the same or similar results? You should do one with power fc :D…lol
on stock t25 hurricane w/ powerfc did 266rwhp/259rwtq with a bit more boost… similar setup but with FMIC so i dont see any reason the powerfc cant accomplish the same.
i watched dan work his magic yesterday on this car and he knows his shiznit.
also went for a ride in the car later in the evening and it feels great and super smooth.
I think Dusty was on bigger injectors which allowed him to run ~16psi. At 13psi I was about as far as I was confortable going on the stock injecotrs. The MAF was no close to maxing out, but the little 370s we almost static.
i know i’m a huge noob and this is probably not the right place to ask this question but i’ve yet to hear/witness an actual advantage of map over mafs… can someone give me a brief rundown of advantages? like, particularly on a setup like 98% of SON where the car is an SR with a few bolt on mods
I won’t bother going into the tuning details but both MAF and MAP cars can be tuned to were the driver couldn’t tell the difference between the two. There are many situations were both have their advantages…however I always prefer a MAP based turbo car because of one thing…blown chargepipes.
There is nothing in this world I hate more than ripping 'tec on some back country road or at the track and blowing a lower charge pipe on a MAF based car. If you can’t fix it on the side of the road or don’t have the right tools, you have to try to limp home, fouling plugs, contaminating oil, etc or you better have CAA Gold.
On a MAP based car, no problem. Cruise home just like any N/A car and fix it.
Oh, and new MAP sensors are way cheaper than new MAF sensors…
I pretty much told you/Mark the same thing on IRC the other night (what dan said about pipes blowing off)
Anywho, I’m a total n00b at this as well but from what (little) I’ve read, about MAP being better throttle response wise. I haven’ tuned MAF, but I find it really easy to tune MAP on the AEM
