Default 322AWHP/300AWTQ with EJ25 Hybrid and 18g



From what I'm told this specific Mustang Dyno tends to read low. Should be a little closer to 350-370 but it's a really smooth tune for a DD and the weekend track day every now and again. Tuned by Jake at Dieman Motorsports.

Mods are:
06 STI EJ257 Short Block with 2.0l WRX Heads and cams
FP 18g oil and water cooled
Dieman Enginuity tune - 92oct @ 17PSI
Billy Boat TBE with high flow cat
Autospeed FMIC and Intake
Autospeed Lightened Crank Pulley
Autospeed Up-Pipe
NGK One step colder Iridiums
Perrin fuel lines and rails
Samco Inlet hose
PE 650cc injectors
Koyo 3 row radiator
Walboro 255 fuel pump
TurboXS Type-H BOV

Very nice man thats some solid numbers on any dyno, not to mention a low reading one. I'm kinda surprised that with the 2.5, your peak torque insn't higher than peak hp like many other 2.5s. In any case, very nice, looks like a great DD.

can you run any more boost then 17? i know the hybrids hate lots of timing, but i think you could a little more boost on 92 with the fmic

I asked BV about this and they essentially told me that peak torque will be less than peak hp until you begin to push the limits of the turbo's capabilities.

He tried a little more boost but temps started getting a little high, so he stayed at 17.

Yes I kept the stock cams. I could probably get a little more out of it with a set of aftermarket cams or sti heads but don't have the cash right now. That is part of the reason of the lower torque number on a 2.5l. That's fine with me right now since I'm running stock gears .

peak torque at 5100?????? That sounds like 35r territory to me. When does this car hit full boost?

^ +12345, with the 257 block and an 18g, I would think full TQ would be no later than 4k

What did you have to do to the heads to make them work with the 2.5?

Bolt them on. Not being a smarta$$. That is all you have to do though. I am installing my hybrid next week. The 2.0L heads bolt right up. Sti heads need to have a few minor things done to work with a non STi ECU but the 2.0L heads are a direct fit.

Nice numbers. I am hoping for a bit more out of my 20G hybrid. Hope I don't get boost creep with my td05h wheel and 7cm hotside.

not to sound like a killjoy but it seems more like the dyno reads pretty high.

Those #'s seem very atypical for a 18G especially only @17psi.

Is the late torque and low boost have to do with running the 2L heads? The 18G shouldnt be much laggier than a VF39 and my peak torque is 3400@323?333? I know u've got a FMIC but still.

Unless maybe thats a 8cm Td06H 18G with some port work or similar. any clipping?

I don't think any of the EJ257 hybrids match the full EJ257+AVCS head as far as spool. I'd guess AVCS is worth just as much as the extra 1/2 L. Maybe more... we don't see too many 2.0L AVCS engines to compare, and if we did the heads would likely still not be directly comparable to our US AVCS heads.

It also looks like that graph has a lot of smoothing applied, which makes the peak hit alittle higher than where torque actually starts to level out. It might actually be more like 4500rpm.

I wonder if it wouldn't be a good idea to get cam gears on that and advance the cam a bit to move the power band down.

Yeah.... I think a lot of us guys who did shortblock swaps when the STI shortblock became available to buy through dealership didn't realize AVCS made such a difference with medium sized turbos like the 20g and Green.

shucks

Actually a lot of the benefits of AVCS can be made up for with tuning on the hybrid blocks. I generally see very similar spoolup and torque

kind of an odd statement, because any tuning that can be done on a hybrid is also present on a AVCS motor +AVCS tuning. So basically all else is equal except for the AVCS.

All down to the tune, technically the same tuner on similar modded vehicles the AVCS should outspool. The hybrid may just require more fine tuning to get it close.

I'm just saying that AVCS isn't really all that. It just provides a slightly different approach to get similar results. Most of the advantages I've found from AVCS are in the form of drivability and fuel economy. It can also help with torque when running relatively low boost levels.

Thanks

i'll trust you, I really don't know that much about it, I'm not trying to say AVCS is super awesome or anything like that.
