MAP EF2.5 tuned by Cobb Tuning - Plano
Love my EF2. No noticeable lag. 449HP/381TQ (Spraying Meth/water) I didn’t go with the EF2.5 because the minimal benefits didn’t justify the loss in spool for me. I read that many MHI users like their turbos, but looking at there dyno sheets, the low end isn’t there like with the EF2. I think its the best for a stock bottom end/DD.

No issues to speak of! MAP made a ton of changes/revisions since the original EF-series turbochargers debuted, all in the name of reliability and durability. I'd put their turbos second to none, people just need to remember that aftermarket turbochargers will always have a higher failure rate than OEM since they're pushed much harder. I sold the car back in March with 70k miles on it and it treated me well. I always ran Mobil 1 Extended Performance 10W-30 with 5k change intervals and gave it a few seconds to cool down before shutting off the engine. I reused the factory oil line.

Sorry to bring this thread back, lots of good info though...
Has anyone posted a dyno of the new MHI turbo to compare to MAP's offerings?
I don't mean to support a competitor, just help people make an informed decision I guess.
For me the ef2 seems ideal, just want to do my homework and not regret getting a MHI.

Blue = local MHI 18K w/Kelford-B cams
Red = my MAP EF2 (stock cams)
Green = my MAP EF2.5 (stock cams)
Now imagine if either of my setups had cams too

From what I've seen locally, the MHI 18K makes the power of an EF2, but spools like the EF2.5. One locally needed cams to even hit 400+whp on 93-octane (my EF2 did that on stock cams...same dyno & tuner). Otherwise, our setups were very similar with full bolt-ons. Blue = local MHI 18K w/Kelford-B cams Red = my MAP EF2 (stock cams) Green = my MAP EF2.5 (stock cams) Now imagine if either of my setups had cams too 

What is really crazy is that your ef2 made only 16whp less than my red on a built motor including cams. Same Dyno
Looking back your Ef 2.5 made 8 more hp than my red and here are my mods:
Fp red ported
Turbosmart 22psi wastegate
Ported head
Milspec 64mm tb
Dw1300 injectors
Aem 320 e85 fuel pump
Invidia cat back exhaust
Ams downpipe
Ams test pipe
Ets intake
Ets licp/uicp
Map rev 2 intake manifold

My cars have been on DB's DynoDynamics, MAP's DynoJet, Cobb's Mustang, plus other local Mustang dynos. What more proof do you need? Guess where Cobb's reads? Within 3% of the other local Mustang. The last dyno day down here someone actually did a pull at Cobb then drove to the dyno day...< 1% variance. Anyway, enough is enough, it got old years ago yet you continue to hate for no reason other than to bash a shop you for some unknown reason don't care for. Maybe because your car barely makes it out of the garage these past few years? Just a thought.

That is a long way to prove something I already know is true
I will never be silenced! muhahahahaha. I suppose I could strap it on Ron's Dyno, make 400 then go down there and make 450whp...but that is a lot of driving. Maybe this next fall or something it will be a good vacation or something. I don't want to go when its hot.
edit: And if his car made less power, something had to be off. I am not knocking your ef2 or 2.5 setup kracka, it was well setup but his mod list suggests he should've been making quite a bit more power, something there seems fishy.

His sig said FL, so I assumed it was a different dyno.

I encourage you to drive down anytime, and will be very interested in seeing the results because I know exactly how they'll end up
He was local at the time, but has since moved. I love how you know something as fact, yet have never been to the shop or even ridden in a car they have touched.

Regardless, I don't really care much to squabble over dyno numbers anymore. one of the reasons I like my VD now, as I just tell everyone the numbers are potentially bogus up front then no arguments can be made. I enjoyed wasting time talking about numbers when i first joined the forums but its become tiresome and no one wins. It's a tool and the only true measurement is the same dyno same day. Otherwise its to be tossed out the window in my book.
Your setup was great and the fpred guy had a nice mod list as well, both cars are probably plenty fast and we can all enjoy fast evos.

Agreed 100% on dynos being a tool that shouldn't be compared against anything but the same dyno.
