Basic Bolt on mods intake, exhaust tuning guide

[Byrd]

"If you want more than about 35-40 wheel horsepower gain then your going to need to go Forced Induction FI either Turbo or Supercharger, just skip NA mods "




Thats weird to me... Who gets FI with stock exhaust / no E85 / no tune? All NA mods are perfect add-ons to FI and should be first in the build.. except for the Perrin inlets and pulleys the FI replaces

@steve99 been contemplating about the Perrin cold air intake. Would I have to adjust anything with my tune, or should it be "ok" ?

most turbo kits require different header than used for NA

Yes you could re-use most NA header for supercharger except maybe Nameless or PLM header

most turbo kits and many supercharger kits don't use stock intake or require a different intake setup than you would use when NA , to fit turbo or supercharger and/or drive belts pullys ect.

A lot of people move from OFT/tactrix/brzedit tune system to Ecutek when they go FI as its the only system that supports flex fuel at present and most FI tuners use ecutek.

Unless your using the OFT SBD specific FI kits

Many will upgrade to 3" exhaust components on high output turbo setups, where 2.5' is suffient for NA and also keeps noise/rasp levels down NA, turbo's are great mufflers.

The 2.5" perrin intake is fairly close to stock maf scaling, but would benefit from custom scaling for best results

The 3" big maf definitely requires maf rescale to be safe.

honestly if you NA then leave intake stock , just a drop in filter will get most of the gains you can get from an entire intake without the associated hassles.

Thanks for the info man! Personally im staying NA & If I ever decide to go the FI route (supercharger) I'll be okay because Im getting all NA mods you listed except for a header. I enjoy my current exhaust setup too much to change it up

Preferred - aem tuned intake or grimmspeed?

Their is not much power in intakes, the grimspeed will work well as its wont require maf scaling

Nice job steve!

If anything the supercharger is the best FI option to keep it feeling like stock, dont forget about the electric supercharger either. Always a good alternative if someone wants right on that edge between NA and FI hp.

Major props for this thread! This will be very helpful. Thank you!

I'm interested in whether or not properly deleting the cat in the stock headers would produce most if not all of the gains as some of the major third party company's headers... I have a turbo kit on order and wouldn't mind deleting the cat and playing with stage 2 before I go boost but I don't feel like spending a fortune to do so :P
Ive also notice that there is a single digit percent difference between the "unequal-ness" of the ft86speedfactory header vs stock... would I then use the Stage 2 UEL or Stage 2 EL file?

The stock header lacks the proper collector and scavenging that the aftermarket ones do so it will limit your power. It's built for economy (cheap), not necessarily performance.

If you're going turbo, you'll already have a manifold as most of them all come with one or you'll need a turbo compatible one.

You won't want a cat in the header if you're turbo. It will get burned up pretty quick. You'll also want EL especially if going turbo. The difference on N/A is pretty minor with torque response in different areas, but turbo you'll start to see the gap between UEL and EL.

see perrin post here the stock header was better without cat but not as good as aftermarket catless headers

This and you would want to run the EL tune.
