What can a 2g really run for boost?
 

I have a 95 tsi with a fmic, tunner, injectors, and a evo 3 16g ported and polished. What can my stock motor really push for max boost?

This question has been answered millions of times with a similar setups.

Whats a Tunner? AFC? Do you have headstuds otherwise you cant push much more than 20. You need a bigger fuel pump also... Are you running pump gas or race? Endless questions can be answered.

Get some of those minimums on the car and then have it dyno tuned by a pro shop, they will setup your boost at a good level.

i have a 255, safc, no head studs, and non oxygnated mix with 100 for gas.

It usually comes down to the fuel. The motor can handle more power than that turbo can make, but it will depend on the tuning and fuel quality.

Well i was going to go down to midway tonight and run 100 and tune to that before i go there. what boost do you recccomend to be at a safe level? 20, 22 im not sure.

Re: What can a 2g really run for boost?
 

17psi. Running anymore than that would not yield any gains since that small turbo would be pushing nothing but hot air. Just because you can run 20psi doesn't mean that the air charge is of good quality. 20psi on a T25 and 20psi on a 50trim are not the same thing.

When I ran a T25 I ran 17psi daily, it would spike to 20psi since it spooled so fast and then settle to 17psi until the RPMs went over 5500 and then the boost fell off.

I dont have a t25 i have a ported and polished big 16g evo III. Now what do you suggest for boost?

Re: What can a 2g really run for boost?
 

100oct? If its good then 20psi should be ok.

Re: What can a 2g really run for boost?
 

20psi should be dandy, even on just 92 octane. Get some dyno time in with one of the local tuners and get a decent tune on that thing. with 100 octane you could probably do a bit more, but I wouldn't push it too much, 22psi or so?

Re: What can a 2g really run for boost?
 

Ditch the safc and get somthing what will log knock and afr's.

I do have a Wideband to tune with. For nock you have to get a dsmlink right. I heard that you cant datalog with a pda on the 2g?

Re: What can a 2g really run for boost?
 

Yes, you need something like dsmlink to read knock. Yes, you can datalog 2g's. I have dsmlink loaded on my laptop and my palm pda. That's nice because then i don't have to keep the laptop in the car all the time.

You can datalog on 2g's even without dsmlink with products like pocketlogger BUT you won't get knock readings, so those products are kinda useless. You can datalog timing. When you see timing being pulled back then you pretty much ASSUME it's knock.

Just get dsmlink. If you have a 95 talon that's your screen name says, you'll already have the correct ECU. Just need it socketed for the new chip.

First and foremost learn how to spell. BAH!
Secondly, get on a dyno. On my 16g I get knock even at 15psi with 680cc injectors because its not tuned. Tuning makes a huge difference.
Thirdly, if you want to read knock on a PDA I give you this quote from the DSMlink site: "- Can I use DSMLink with a PDA?

This question is a little tricky. Yes, you can, but only due to the generosity of one of our more active users, Hal Landry. He has devoted a good bit of his personal time to develop a version of the DSMLink client that runs on a Palm device (true Palm, no Visors or anything like that). The requirements include Palm OS 3.5 or later with color being highly recommended. The original software was written using a Palm IIIc, which can be had these days pretty cheaply off E-bay. This question is a little tricky because we don't want to suggest that the Palm is a fully supported platform. It's not. Hal doesn't have to do any of this. It's great that he does, but don't buy DSMLink assuming you can get all your questions answered related to the Palm interface. Hal makes the Palm software and updates downloadable for registered DSMLink users via the user's group forum."
