Big Turbo

Really a hacked 2g MAF is good for 500whp, damn ok well I guess i'll just go with that then.

No, it is good for a certain airflow not horsepower. And th point at which the maf stops reading accurately is different for each maf.

Thanks guys good info, Well im not going to go with a standalone becuase thats just to expensive and, to all who posted im sorry if you thought Im putting this motor in a 1991 eclipse gst, because thats my old car, I now have a 90 awd with a 4 bolt swap, so i'll will update my profile.

That sucks, I like DSMlink, but as with some other simpler systems i've seen. I just cannot advocate having one set cell value for everything above a certain RPM or load point. Especially when talking about doing this to a motor that has a lot of moeny invested in it. If the OP is going to be regularly turning over 8k, i wold strongly suggest an EMS that is capable of mapping those areas and not just pegging to one value and holding it.

This would mean that above 8k RPM at WOT, if he was at 11:1 at 25psi, he would be leaner at anythign higher adn richer at anything lower,leaving you to set the boost one way and leaving it there unless you're just turnigng it down in which case you would go richer (safe) but if he was trying to squeek that last MPH of trap speed out adn turned it to 28psi and there's no individual mapping for that PSI then he would stand a strong chance of running lean and hurting the motor. I know people have gotten away with this and i'm not saying it's deadly just because of the way it operates above 8k, but it sure as hell isn't going to be idiot proof either and a whole lot less than ideal for a car that sounds like it's going to be spending a lot of time above 8k to keeo that turbo working efficiently.

My 0.02

I agree with what you are saying. The way I would do it is tune till 8,000rpm then do a wot pull while datalogging my wideband. Why I am doing this I would also be watching my wideband. I would go to say 8,300 rpm and let off. If all looks good go to 8,500 and so on. If it gets too lean I would richen up the 8,000 rpm point some. Obviously it would be better to be able to tune each point rather than doing it like this. I think they are going to put more rpm points in V3 but am not sure, I will find out and post what they say.

Only a handful can get 500whp at the airflow that a 2g maf drops counts.

A dsmlink car has gone 8.6 so far.

One who would complain about this is one who doesn't realize that 9s can be achieved under 9K. Sure there's no sense not getting more rpm tuning points. But, anyone at this level wants to see the whole map... Which is possible with V3. You just don't need 9k tuning to reach the 9s.

Thats why I posted that. I don't know of anybody actually doing it on Dsmlink forums. I have heard some people say somebody else has done it though. And once your reaching the limit it gets harder to tune the car because of the reading getting choppy. So it would be easier to get a gm maf even if you are not overrunning the maf but close to overrunning it. You could use the fake maf function but it is easier to tune if you are using the maf.

So know one knows where I can get an oil feed/return setup for this turbo?

You are most likely going to have somebody make one for you. You might be able to find a fitting that fits it and reduces it into the size of a Garrett feed line for example.

 

[90AWDEclipse]

Ok i'll see if my brother can make something up that will work. O yea and is the small one the feed and the bigger one the return?

 

[1992awdlaser]

The bigger one is most likely the return. Does it have any other holes for fittings on the center section?

Does anyone sell anything for this kind of turbo, or am i going to have to make somthing up?

Looking at that photo it looks like the small side is the feed and the big hole is the return if thats the only holes on the ceter section. Since it has o-rings you maybe able to get away with a flat plate and just drill/tap holes accordingly. It would be nice if you had that OE plate.

 

[90AWDEclipse]

Nope just those, im glad it's only oil cooled.

 

[1992awdlaser]

Turboglenn, I found out they will have more rpm points to tune at in V3 of Dsmlink.

 

[90AWDEclipse]

When is this v3 going to be out.

 

[1992awdlaser]

They say this year but don't have a specific month. So it could be December. But if you buy the current version you can upgrade later for I think $50.

 

[90AWDEclipse]

Damn well like all you were saying, Dsmlink only can tune till 8k and im going to be reving to 9k so whats another tuning system that will perform like dsmlink, but can tune to higher rpm?

 

[1992awdlaser]

Dsmlink will be fine. Above 8,000 it will use your settings at 8,000. There are plenty of cars revving over 8,000 with Dsmlink without a problem.
