nice thread guys... Im dieing to tune my 2.3L i have almost 5k break-in miles on mine!! HAHA

 

WOT,

You are correct in a general sense like you stated. I'm sorry you took my statement as 'very generalized'. I was posting about the car in question in this thread. A 2.3 Stroker with a FPgreen turbo.

With this application and setup the horsepower will not be increased very much but the torque will, and did.

 

Can't we all get along?

 

I apologize for coming off like i did, but i am a firm believer & have seen engines in action, that bigger is better. Even with tiny *** bores & long stroked engines.

i believe that what we are witneissing here is, despite having a bunch of good guy parts thrown all together, it doesnt gaurantee you big numbers.

regardless, i am certain you have tuned more 2.3 / 2.4's then i have & are speaking from experience.

 

Well, the power should increase a bit, just not a huge amount with a turbo that size. The spool and torque will increase quite a bit however.

I am certain you have more experience with other types of motors than me so we can just buy each other a beer and discuss things more.

 

not true. i'm on an MBC and my evo hold boost Erik.

 

a'ight

Then the question is why does Alain suffer so much taper? Does the DJ load the car differently than the street? And just for the record, I am not talking about the 32 psi boost spike. Obviously this turbo can't support that kind of airflow at higher rpms. I am talking about at/near 7,000 rpms.

Also, do you have boost plots of your car, Charlie. Interested in seeing what it is. I will say that Bryan has shown a few MBC's that taper on stock-ish turbos on their Mustang Dyno. Curious as to your thoughts.

On Alian's car, could it be wastegate preload? Something else? Genuinely curious.

Charlie, can you hold your boost flat-ish with an MBC @ higher boost pressures?

 

Good numbers. Good to know that there are tuners in SoCal that can get good numbers from 91 octane gas. Your car made more torque than the stroker in this thread. Santa Clarita also has very hot weather and both cars are running on 91 octane and FP green.

What other supporting mods do you have on the car?

 

Yeah, pump gas can be a challenge. I believe we hold the record out here for EVO power on pump gas.

483whp 446lbft @ 25psi

2.4
35R
EMS
All supporting mods

Heres a ling to the dyno graph.

We are not talking about a 2.4 stroker, 35r with EMS. We are talking about the FP GREEN trubo on the OP's car vs. vboy's car featured here

http://www.socalevo.net/index.php?op...&topic=46762.0

The OP's car is down on power by 30 hp and makes similar torque to a 2.0 even though the OP's car has a stroker

Both of these cars were dynoed on 91 octane during the hot CA summer and have similar supporting mods. Yet one produces 30 more hp and an equal amount of torque to the FP green stroker car.

 

The 2.0 car did have some additional mods, like a Magnus intake manifold and a 65mm throttle body which I don't think the stroker did (to be fair).

 

Here are the mods of the stroker:

Mods
EVO 8
2.3 stroker RRE
FP EVO Green Ported
HKS 272/272
Cam Gears
Neise FMIC
AMS LICP
Stock Intake box with K&N drop In
720 injectors
Upgraded fuel pump
MBC
ECU Flash
Ebay o2 Housing
Ported Mani
Vishnu 3in TBE

Here are the mods of the other car:

a 2 years old DEJON MBC
metal BOV
stock 9 WG
HKS 272/272
STOCK CAMS GEARS
DENSO 720
WALBRO FP
EBAY SPECIAL DP "LOL"
TEST PIPE
HEAD STUDS
MAGNUS INTAKE MANIFOLD
GREDDY IC
STOCK IC PIPINGS
TANABE ULTRA MEDALION CATBACK

The second car does NOT have a Stroker, does NOT have cam gears, does NOT have ebay O2 housing, and does NOT have LICP.

Yet somehow it is not fair to compare them since the car making more power has an aftermarket Intake Manifold and a 65 mm TB? Come on. Don't you think that all the extra mods on the stroker balance out the intake manifold/TB? What power does a TB put anyway?

It is clear that the OP's car is down on power. Anyone who saw the map would know why.

 

Aren't these two different dynos?

 

I have seen dataplots suggesting that an aftermarket intake manifold can be worth 20whp from 5500rpms+. Datalogs on the TB suggest 5whp or so. I am pretty sure last time I saw Charlie's car it had an intercooler on it, IIRC. He may have forgotten to list it, I don't know. I also think he has an open element cone filter, but Charlie will have to chime in on that one.


In regards to the bolded statement above, have you seen the map? I don't know if you have or not, I am just asking.


Bryan,

Yimi and TT are both DynoJets. I think some have dynoed on both, but I don't remember what the correlation was.

 

Both cars have a FMIC. So let us assume that the IM and TB add 25 hp. Wouldn't a stroker, cam gears, LICP, and O2 housing balance this out? We know from BR that the ebay O2 housing adds 15 hp. I am sure the rest of the mods would add to 25 hp that you sau are coming from the IM/TB combo.
The OP sent me the map.
