Ok, here goes. I'm debating whether or not to get a SAFC-II. I am getting a custom road tune by Al in December and I'm debating if I should also get the SAFC-II on top of the tune. Any feed back would be great. Also, I've done my searching but nothing on this subject. Please no BS post. Only post if you have an opinion on the matter. If not, DON'T post.

My goal is to get over 500 whp. After that, I'm done. I'm building this thing slowly. I'm installing my Cams and Cam gears this weekend.

My last Dyno slip was 279 whp, July desert heat.

Thanks in advance for the input.

 

Well, it depends the SAFC II on top of Al's tune would help on the track if you run race gas to get the most power out of your car. You would needs a wideband 02 for that and a pocket logger will also help but not necessary. I have a mail in flash and have a SAFC II to tune some of the top end a little.

 

Hmmm, going for 500whp. It might mean moving on to bigger and better things.
AEM EMS for starters.

I highly doubt that you searched and didn't find anything, because I've commented on this very thing many times...and within this forum.

But anyway, yes, having an S-AFC on top of a flash is a pretty good idea, but only if you will be using race gas at the track or if you plan on adding mods later without getting a reflash, in which case you'll be relying on the SAFC to fine-tune the new mods. With a custom street tune, though, there will be very little to gain as far as daily driving, so I wouldn't bother unless you'll be racing it with race gas.

Also, I'm a bit confused why you're talking about 500whp when you only have basic bolt-ons. To get 500whp in Arizona, you're going to need a huge turbo like a GT35r, and you're going to have to at least be on meth full time. To properly utilize such mods, you will probably want a standalone. Al can flash big turbo cars, but it's not optimum, and it doesn't make much sense to spend all that money on a huge turbo kit then rely on a basic flash. I can tell you for sure that you do NOT want to rely on an S-AFC when you get into the 500whp range...

 

I'm with these guys. On a 500+ AWHP setup the advantages the EMS could provide are huge. Is there some reason you don't want to go standalone? Like running the car in a class that restricts you to a "stock" ecu or something?

Thanks for the input. I agree with the bigger turbo set-up. I will be doing a stand-a-lone when the time comes. But right now I'm not there yet. I will be doing all of those things in due time. My pockets are not that deep. When I said I want over 500 whp, I know that I'll have to go to a bigger turbo, ect.

When I did my searches, there was so many things that didn't add up on the subject. There is so much info on this subject that I spent about 4 hours searching. I finnally just gave up. I'm sorry if you guys already talked about this, maybe my mind just died after the 4 hours. Thanks again.

I'm not going to race it yet. I'm just not there yet.....

 

Ok, so the 500whp is not relevant to the question then, so we can ignore that part.

That brings us to the racing. What do you mean "I'm just not there yet"? I raced when I was stock, I raced with just an S-AFC, I raced with a cat-back/mbc/safc, and now I race with tbe/mbc/safc. I drag race, road race, autocross with stock suspension and either stock or race tires, depending on the situation. You can race with mods, without mods, tuned, or untuned, fast or slow, pretty or ugly. So, whatever the reason that you won't be racing is up to you, but the fact that you won't be leads me to say that you don't need the S-AFC. With a custom street flash, you will have a great tune that is close enough to optimum that it won't be cost/time benefecial to slap on an S-AFC, imo.

 

500whp... Your going into a different realm.

When I say, I'm not ready for that.....I mean I don't have the time.....I'm working to much right now and just don't have the time.... I know it a different realm with 500 whp. Everyone has to set goals as to where they are happy at and this is one of them for me....Reading all these valuable information post, I feel it's very obtainable to get 500 whp out of an EVO. Most of the time, people buy the EVO and that's it. They are so extended with the payments that they can only do basic bolt on's. Just my opinion about this.....

 

Thanks.

 

350-400whp is usually enough for people, and it has little to do with being over-extended. It has to do with having insane power that you can barely even make use of, and being able to make that much power for very little money, yet lots of reliability. Maxxing out the stock turbo allows you to not touch the engine, not spend a ton on a standalone, not spend a ton on an upgraded turbo, and not having to deal with need the complications associated with a bigger turbo. Wanting 500whp puts you in a whole new realm where you will need to spend a LOT more money, receive a LOT more tuning, and deal with a LOT more issues. The clutch alone for such a setup would cost more than I've spent on all my mods combined in reaching 12.0s in the 1/4-mile.

THere's nothing wrong with wanting 500whp, but it's not very realistic for 99% of Evo owners, and would only be recommended on a garaged car that isn't driven daily. Spending 30k on a car then another 10-15k on mods for a play car is pretty tough for most. I drive mine daily and am happy with 300-330whp on very little money spent, since 12.0s beat just about everything on the road...

 

Thanks for insight......I agree with you about the 500 whp. It's just one of my goals. I'm not saying that I'll do all of this overnight. It might take a few years to achieve, but I want to at least get close.

 

Ok, here are my thoughts on getting to 500 whp. I might be way off here, but here goes.

Current power mods:

Ram-Air Intake, Down-Pipe, Test Pipe, Cat-Back Exhaust, Apexi AVC-R, 255 Fuel Pump, LW Crank Pulley, Buddy Club I/E 272 Cams, Cam Gears, Custom Road Tune DynoFlash.

Other mods:

Turbo-Timer, S. Techs, Short Shifter, APS BOV.

Supporting mods to get close to 500 whp:

800 cc injectors or higher
fuel rail
AEM EMS
GT35R Turbo Kit (includes E. Manifold)
Eagle Connecting Rods
Forged Piston Kit
Piston Ring Kit
Kevlar Timing Belt
Head Stud Kit
Metal Head Gasket
Bigger Intercooler
Racing Radiator
Conrod Bolts
Crower Springs & Retainers
Forged Valves
Intake Manifold
Up-Grade Clutch
Up-Grade all lines to braided SS lines (brake lines, etc.)
Alcohol Injection Kit

** The reason for the internal is get more strength. You should be close to 500 whp with this mods. It might seem like a lot of money to do all this. The ones in red are the high dollar items. All the rest are at reasonable prices. Also, if you learn to work on your car, that’s just more money to save. You don’t have to pay someone to install anything.

 

That's what I'm talking about.
With that setup you'll be @ 600whp. Go for it.

Thanks, I was just saying that 500 whp is not easy, but easy to put down as a plan. With the mod support we have, it's easy to get there. I don't think it's a different realm. It just falls down to how much do you want to spend!!!! That's it. If you take it slow and part by part, you can see exactly what's wrong with it. Like if you do everything at once, you have no clue if something messes up. Just my thoughts.
