gain from 16g over t25

[word2wombat]

how big of a difference will i get out of swapping out my t-25 to the 16g??

Yes you will feel a little upgrading on a totally stock car you will be flowing more air or (cfm). Its not gonna send you to the moon or anything but you will see gains. Then after you get a couple more mods you will REALLY see some gains.

As for the pissing match about intake temps......How many cars can you count that are 10's and faster without any intercooler??

Stick on topic and research before you post. Oh and no it will not be a 100 hp gain without supporting mods. Hopefully I didn't miss anything.

Ummm, did you even read the other replies? Shep doesnt use and intercooler and he runs 7's btw.

THAT IS WHAT I WAS SAYING! I was trying to make the point that you DONT need an intercooler at all............WTF

how do you not use a intercooler? Just interested not looking for a fight since this thread seems full of them.

 

[spinz4]

Just make yourself some custom intercooler pipes is all. It's only going to benefit you for drag racing though. My piping can be turned to do this, just have to have the right stuff.

Some people use methanol as a fuel, it significantly lowers intake temps to the point where an intercooler might not be required.

 

[spinz4]

Alcohol injection as well.....But none the less an intercooler is not needed for a 1/4 mile pass....

Methanol/alcahol. If you ever go to the track and see a blown v8 with a hat on meth you can sometimes see condensation building on it before a run. It can lower intake temps below ambient

Almost anything other than the T-25 is an upgrade. Everyone knows this.

I dont think a person new to dsm would know this

Shouldve been more clear, I ment the max output difference of both turbos when I said 100hp difference and I was baseing it off of the vfaq link I posted.

That's a good question and there are a lot of variables that can affect overall power output but I'll try to keep it simple and leave out anything not pertaining to this discussion.

The 2.0 engine at 100% VE can ingest 2 liters of air, once you reach that point power is pretty much capped. In some cases an engine can exceed 100% VE but that doesn't really matter in this case. To increase the power level you would need to increase the density of that air, density is determined by pressure and temperature. If you were to upgrade from the T25 to an EVO 3 16g, and for the sake of discussion lets say the boost level was 12 psi on both, where is the additional power going to come from? Air volume is the same, air pressure is the same, there is only one variable that's been changed. Temperature.

Hope that helps

Thats interesting basically its just like sizing parts for your set up . So buy a turbo depending on what kind of boost your going to run etc.

I dont really believe that. If you had absolutely nothing else done at all maybe. But a minimal bolt on car you will at the very least hold more boost to redline.

They both can hold boost to redline at stock boost levels because your not at the max efficiency for the turbo. Youd have to be at the turbos air flow limits before it starts loosing boost by redline because youd then be outflowing the turbos cfm capability. To max out a turbo youd either have to be running high boost levels or be revving to the moon .
At 12lbs either turbo can flow to our 7k redline. The only way your statement would be true is if were talking something like, boosting at 12lbs; the 16g will hold boost longer if your redline were to be 12k rpm + or something because then youd be pulling a lot more air and have a higher VE at those rpms.

The thing is that if the car had any boltons it would most likely not be running stock boost anymore.

 

[nightspeed87]

youd need bigger injectors anyways and since the 16g likes to creep without external anyways then yea itd be a big gain because youd be running bigger boost on a turbo that flows twice as much...

In which I mentioned that also....

Well actaully, when you swap the t25 for the 16g, you aren't changing boost pressure, but you ARE changing volume as well as temperate. The 16g would flow more CFM at the same psi as the t25, so although it will be minimal there would be an increase in power just by switching to the 16g.

 

[gsxeclipse97]

^^ I agree when i went from the t25 to a 14b the difference was huge. there was a slower spool up time but at 15psi the car pulled hard. that was before i did the 6-bolt swap. But just switching from those two turbos there will be a very noticable difference. I would give him at least a 20-30hp difference just with the switch. Also the e316g flows more than twice the air a t25 does.
t25=250cfm
e316g=550cfm

Hey heres a brilliant idea buy some fuel mods and a tuning device first, and then its safe to say its a hella lot better.

 

[word2wombat]

and what would you suggest as far as fuel mods

 

[DSMSpyder99]

enough to make me get 17x8 with 245/40 and still lose tracking in 2nd gear

 

[boostnhard]

if he waps just the turbo and nothing else he'll be plagued with BOOST CREEP. l still am!!!!!!!!

I have been under the impression and from personal experience that the t-25 doesn't pull hardly at all over 5k rpm's. This is at stock boost level. My boost gauge always shows it drop's off at higher rpm's. I have also read a ton of posts on here saying how the t-25 sucks and will die off over 5k. This is not correct? My turbo pulls nice but loses alot of pull once i get to over 5k. So wouldn't the evo316g pull hard to redline?
That to me would be a huge difference in itself! I wind up shifting my car before 5k every time cause it feels like there is not any more power above that with the t-25. I have not done too much research into this topic, Although i will be upgrading to the evo3 ocne i finish my supporting mods, but that is what i have from my personal experience.
