2014 FR-S AT - Realistic Gains ALL Bolt On
 

Soooooo.....IF I stay NA, what is a realistic number to shoot for if I did the following:

Intake
Header with cats
Complete Exhaust with Cats and Resonator
ECU-Tek Programming

I understand the AT's lose about 10hp at the wheels to the Manuals so that being considered, could I get to 190 at the wheels? 230bhp? While I am sure some of you have gone with full bolt on's I haven't seen posts by anyone with AT, full bolt on's and programming. Sorry if I missed it. I know dyno's and opinions vary but I am trying to establish some realistic goals to acheive by summer. I know 6k will get me FI but I am leaving that off the table for now.

Thanks

On a Basic NA setup with the following parts:
Revworks UEL Headers
Injen Intake
Invidia N1 Catback
AVO Overpipe
J2 Catted front pipe
Stage 1 NA Tune

got me around 178WHP


If your talking about more realistic, then the only way to get to 190+ is by going FI. AT's lose more than just 10hp vs manuals. Alot also depends on the tuner and fuel quality.

here is my dyno sheet with above setup

I hit 190 w E85 on a DynoJet
(All P&L) Catted header, Overpipe, catless front pipe & Catback
AVO silicone inlet tube, Perrin Foam filter <-- not very relevant I don't think...

Here's my Dyno sheet when my car was NA. Mods were revworks header, overpipe, testpipe, JDM TRD exhaust, HKS premium suction intake. We did a Dyno day with around 8 cars, 3 were ATs and we confirmed that the ATs were down 10whp from the MTs. That said, the MTs baselined around 155-160whp stock and the ATs baselined 140-145whp stock. After tuning almost everybody went up almost 20whp. But the ATs were still down 10whp.

hmmm thats weird, let me dig around and look for my baseline dyno. i know mine was higher than 140

heres my baseline, Blue is stock and red was after injen intake install both are on OEM ECU tune

For some reason the Dyno numbers here always read lower than what you guys get over there. Must be the heat or humidity we have here.

hmmm i think so as well. didnt realize you were from Philippines, but i know from experience you guys get 100oct there easy so the numbers should be better.

Wow talk about variances in baseline's, sheesh. So aither way it looks like 20whp is max to be expected after all those mods and a tune, probably around 230 at the crank. Losing 50hp to the wheels is really bad, maybe it is just the nature of the beast. My current car is 335is which is notoriously underrated and put a healthy dose to the wheels (I know, I know not fair..). Looks like boosted may be the only way.

here is my turbo dyno sheet

WOW, now those are some AT numbers right there!!!!

I hit 190hp 151tq with the mods in my sig on 93.

Hot damn I had no idea we lost so much power...Ide be ok with 185ish NA but wouldn't even bother if I couldn't reach that without a miracle.


How much do you think a drop-in + catless front pipe would make on 93oct?

At least you're not high altitude.... At 4500ft I'm down another 15-20 HP from stock. So my manual is as slow or slower than an auto.

Thanks bro, made me feel better :thumbsup:

Looks like i have a shot at 170+ which is good enough for me. My weight loss plans are -100lbs which I believe is doable (but optomistic). If I can lose the extra weight an AT costs us and bolt on another 20hp at the wheels it's gotta help.

Eternal optomist :thumbup:

-25 lbs battery $300
-30 lbs spare tire n such
-15lbs catback $600
-7lbs header $600
-12 lbs aluminium DS $450
-5lbs crank pulley $125
-2lbs sound generator delete
-1lb car manual
-32 lbs AP racing brake kit $2k
-16lbs light weight wheels $1k
-6/8lbs catted front pipe $500

OP you haven't said or responded to anyone mentioning E85 yet, is it not something you're interested in or? Understandable if not, I'm just wondering.

Your NA goals are definitely attainable with bolt ons and a proper E85 tune I'm sure.

There are honestly so many different variables on a dyno.. heat, altitude, quality of gas, and type of dyno (mustang, dyno jet, etc.). I know a few local guys pushing over 200-210 to the wheels with automatics on e85 and typical bolt-on mods (ECU, exhaust, tune).

Without e85 you're looking at around 180-190 whp.

I should dyno this car and see the "money" number while the weather in South Florida is still cool, oops it's 76 degrees again

Err... stage 1 tune? Why? O.o

just to get me by until my turbo came in.
