My friend Mike's Talon setup plans.... opinions please!

[Thor06]

Ok, so most of you are familiar with my friend Mike and his POS Talon. Well we are seriously reconsidering his plans of a rebuild, DSMlink, 50 or 60 trim, and everything in between. Hes getting a parts car, its a 92 AWD shell, no drivetrain except 4 bolt rear, eprom w/ palm hookup, and Apex springs with AGX's. So heres the new plan, mainly due to money: SAFC 2 with pocket logger (all we need is the software, the ecu is ready for a palm pilot and we have one), Evo III 16g, 550's, and a walbro 190. He already has 3" turbo back, and needs to put in his boost controller and FMIC (10x24x2.5, still needs piping). Does that sound like a decent setup? We are thinking about not going DSM link because its ~$600 then we need to buy a laptop besides, where with the SAFC all we need is the SAFC (used? only like $250 new anyway) and all we need for the pocket logger is the software. 550's should be ok right? The 550's and 190 should suffice with the Evo III right? Thanks guys.

EDIT: Please dont tell me how much better DSMlink is, with his funds, its just not an option.

680s at least, if you plan on maxing out that turbo at least. Sounds like you have a setup good for ~300-350hp. Also its the same thing I have.

[Thor06]

>300 but <350 is the goal. Thanks pr_ricer, anyone else?

[crunchymilk55]

550s are enough fuel for a 16g unless it's high boost. To make above 300, you'll need high boost. Here's the problem, you can't run 680s on a SAFC-2. Some people say you will, but they are just thinking about injector compensation. Of course it has enough compensation, but the problems is how much airflow the ecu sees. It doesn't see that much so it advances the timing alot, which causes knock, which causes the timing to be retarded severely, AND hurts the engine / headgasket especially.

If he can deal with less than 300, then 550s and safc2 will be fine, if he really wants to squeeze everything out of that turbo, he will need the rest of the boltons, including cams and smim, along with a better engine management system to put down 350+. Making that much power with the evoiii is very rare, and difficult.

what if you use a gm maft and the safc? Can't he use 680's then?

[crunchymilk55]

yes, but it would be difficult. He would have 0 in the injectors with the maft, THEN tune on SAFC. Any errors from 0'ing in the injectors would continually cause problems. Not to mention the price of dsmlink if probably less than the GM MAFT, GM Translator, and SAFC2

Not really, I have about 400 dollars in all the stuff I need for mine.

Smart shopping and it can be done for less. lol

[crunchymilk55]

well you got a good deal, but 400 vs 500 for link is no brainer. That combo doesn't do a quarter of what the link does.

But they still gotta shell out money for a laptop too if they don't already have one... And who knows how much more that could cost them.

[Thor06]

Yeah, 80% of the decision to go with the SAFC and pocketlogger is due to the cheapness. It will be $600 for DSMlink then $300 for a cheap ass laptop or $250 for SAFC and we already have the palm pilot and the ECU we will get has the hook ups for it. How much is "high boost"? He does have the stock head gasket, so high boost really isnt an option anyway. I have a feeling he'll be fine with 250 or so.

[crunchymilk55]

If he's fine with 250, then safc2, 550's will be good, just check the injector duty cycle.

[Thor06]

You made 250 on 17lbs of boost and a crappy tune right crunchy? How much boost will the stock HG hold?

[Talon69]

The way i see it is if you have DSMLINK or want to get it go the biggest you can on injectors. I was on DSMLINK forum and this guy is running 1600cc inj and he said they run sweet with dsmlink. I know you do not have it but its the way to go man. Your spending this much. Might as well do it right and get dsmlink.

[Thor06]

Thats just the thing... we already have a pocket logger, all we need is the SAFC. Later when he is making more, DSM link might happen, but for now we gotta make due with what we have.

I made 250/295 with a boost spike to around 22, then boost tapered off to around 17, that's why my curve was all messed up, cams will fix this. It wasn't a crappy tune, it was a safe tune. I need this car to last, so we were very conservative with timing and fuel. It could have easily made more power, but that would have just been a number, I care more about the tune the car sees every day.

The stock headgasket is usually good to about 21psi or so. BUT, knock will kill a headgasket MUCH faster than running a lot of boost.

Just remember that with the safc you can't retard knock, so once you start knocking, the computer will retard timing like a mofo. It's doable, but the engine will have to be in great shape with a good tune.
