how to increase hp staying n/a
 
How do you do this?

Same as its always been. Our cars are more responsive to bolt ons than most ...it is an ongoing discussion akin to the Torque dip phenomena which seems to be tuning related.

Header back exhaust ...better intake with less acoustic variations ... and just overall optimization of the rotating mass. Pullies , drive shaft, fly wheel ... let the engine breathe easier ..but this is basic stuff but it is indeed odd how you can gain 5-7whp from an exhaust alone.

Improve response is the best u can do. I/H/E, oil cooler, mods against heat sink, light weight rims, cf drive shaft, lightweight crank pully, gut the car ect ect. Overall weight reduction is great but lighter rotational mass is the best thing you can do IMO. Once you have ur bolt ons and weight stripped down then you should fight heat sink. These engines run toasty. First things I did was heatwrap my intake and install an oil cooler.

Also if you intend on tracking, brakes and tires will make you faster then bolt ons will. Last but not least, seat time. The faster you are the faster your car is.

Thanks guys. I figured weight reduction pays a toll in an n/a motor. Main reasons of staying wanting to stay n/a is mainly I can't afford a turbo and I think being a built all motor fa20 will be unique since others are all going turbo/supercharged

@Sitha@ft86club

For this car specifically, people waste a lot of time and money doing what worked best in other cars first. Don't do this.

From a cost perspective and specifically, for this car the following make the biggest gains on the dyno and to driveability.

First:
1. Tune
2. e85
3. Catless Header (either EL or UEL, next to no difference in power).

Then:
4. Drop-in filter (don't bother with Intakes, they make next to no difference in this car)
5. Catless front pipe (Keep in mind if you removed the cat from the header, also removing the cat from the front pipe will smell a bit).
6. Overpipe

That's about it. Most other mods give no extra power whatsoever, including catbacks (mid-pipe and muffler). The stock intake is very well tuned and already "cold air". The stock mid-pipe is still used by many people that track this car in real races. No mufflers have proven to give consistent gains on the dyno for a NA car. The engine's internals have proven to handle N.A. power without upgrade, so don't wait around for them.

Now depending on your goals, you can start making the car lighter to make it quicker, brake harder, and handle better. Start by reducing unsprung weight (upgrade wheels, tires, suspension, brakes). Then perhaps reduce rotational mass (upgrade drive shaft, pulleys). Finally go after unnecessary sprung weight (delete spare and tools, delete washer fluid, add track pipe or lightweight catback, add aftermarket seats, delete rear seat, add aftermarket battery, gut interior, a/c delete, dry CF fenders, hood, roof, trunk).

During all this don't forget to dial-in your new components. Re-tune ECU, re-align suspension, corner balance, and swap fluids. Keep your tires rotated and at their correct psi. While you're doing all this (or better yet before), driver mod. Get instruction, know your car, read offline. This will make the biggest difference of all.

Lastly, don't forget to have fun.

I'd disagree. If you talk to any shop that's dealt with many of our cars they'll tell you bolt-ons make little difference on this car without a tune. Hell, it's not unusual to see someone come in with exhaust, intake, pullies, etc and they dyno lower than stock. My stock dyno numbers were higher than a number of other locals who had basic bolt-on mods.

So top of the list should probably be tune.

Agreed.

Great post! Everything I have read over the past year agrees with you!

E85 IF we have it. Closest one is snoqualmie bro so think that over. Also why not talk to bob instead of making posts like this?

I did talk to bob a bit about this cause I was deciding on the A V O turbo.
or if i should stay N/a.

Staying N/A because I got 2 many tickets and Im under probation right now so if I get another ticket, my license are gone for a year.


This dream will have to wait, cause I have yet got myself into some deep shit.

Thanks for the replys guys much appreciated. :thanks:

You should invest in cheap coilovers, bad camber plates, and heavy wheels if you're trying not to get any tickets. #LowIsSlow
