Get the TII hood, it'll keep your intercooler/engine/intake much cooler.

 

i appreciate everyones input, got some good advice. I guess, once the FM is installed i'll take it easy till i get some 720s and i'll debate on wether to save and get a standalone or maybe go ahead and get the f-con. prolly just get the f-con, b/c its cheeper and for the time being... i'm not really gonna mod much more. maybe if i can manage to hold on to the car for a couple more years, after i'm out of college i'll prolly upgrade the turbo setup and get a standalone.

 

as long as you're at stock boost levels and everything is working properly, theres no reason to take it easy, you should enjoy the car. lucky for you, you have an S5 turbo so theres really no need for wastegate porting, it should still run around 8 pounds if everything is hooked up right. the best way to check what you're running is to get a boost guage and make sure its at a safe level (8psi). if you dont want to get a boost guage, you can just remove the FCD, and if you aren't hitting fuel cut, you aren't overboosting. in fact, as long as the fuel system is stock, just remove the FCD anyway, it can only hurt you.

 

Half wrong, half right. If you use the S-AFC to make the mixtures richer it increases the airflow signal. The ECU will think there's more air and will add fuel and retard timing. This is perfectly safe. However most people use the S-AFC to make the mixtures leaner, which reduces the airflow signal. The ECU thinks there's less air so it reduces fuel and advances timing. The FC has quite conservative ignition timing so this is safe up to a point. Large negative corrections will increase the chance of detontion, which is why you shouldn't use an AFM interceptor to correct for huge injectors.

 

Thanks, I'll prolly do that, just to keep things on the safe side till i upgrade the fuel system. I plan on getting the boost guage too, i just havent gotten around to it yet.

 

thanks NZCONVERTIBLE

 

can't you add more fuel with a Fuel pressure regulator??

 

That would increase fuelling all the time, not just at full load when it's needed. It would work, but it's a very crude tuning method that will result in a lot of wasted fuel in normal driving.

 

I am only boosting like 10.5 lbs i'm not going to turn it up a whole lot... will it really waste THAT much gas?

 

since you have S5 electronics you can sell them and get a pretty penny. That along with the money you are about to waste on the piggy back you could buy a used stand alone computer. This way you can have the HP you want w/o cranking the boost up.

Definitely get a FMIC and duct it properly. The stock top mount is good, but after a couple times boosting through gears, it gets cooked and the power fades.

 

A FPR is totally unecessary for mild mods, so that money would be far better spent on an S-AFC so you can tune it properly. That way you'll also be able to save gas instead of wasting it.

 

^^Thanks for the advice. I was got the FPR for free lol so thats why i was asking. I do want to invest in some engine management though... would an Rtek be a better investment than an S-afc?

 

they said above that with the Rtek you need to upgrade to 720's all round so work that into your equations. Look at NZ verts posts regarding the safc on page 2

 

^^ i was thinking just getting the Rtek 1.5 for now until i decide to rebuild and get a bigger turbo. Right now i have 550 primary's and 680 secondary.

 

alright, well the FMIC is getting installed as we speak! should i be worried about not having bigger secondaries??? with the intake, exhaust, and front mount, will my boost and charge be too high for stock injectors and ecu? should i go ahead and full off the FCD to play it safe. I havent had any problems so far and all the front mount will do is increase the density of the air... will there be a big difference?

 

anybody???

 

If i were you i would not push your car until you have proper fuel and an S-afc. Especially now that we are getting to a point where the weather is starting to cool down, that FMIC could pop your motor. Although the FMIC might not necessarily raise your boost much, it will be taking in more amounts of air that will also be denser and this, if not matched properly with fuel, will cause you to lean out. If i were you i would install and AFR gauge if you dont have one already.

 

preciate it, the guy is chargin me 400 for the install on the intercooler, its not a real big intercooler and he didnt have to take off the grill or anything. is this a decent price?
