Ok, I think we can all have an opinion on this. The thread is not about what opinions we have, the OP asked for help in assembling a list of $$$ per HP. So I guess the only help would be whatever upgrade you bought, calculate how much money per HP it is. That simple. It will be helpful for a lot of people.
I'll start: Street Axleback and High Flow Cat Package/ Nameless/ $949 12 HP -->$79/HP

Wow, never thought so many people would give the guy crap for asking about mods. This car was built for people who mod.
From what I have seen you would be best off with working on the exhuast system. My question is do you care about emissions and warranty? |

In any event, I understand what the OP is looking for, but the reality is that this is a multi-dimensional problem that you can't easily solve with a flat matrix. $/HP is too simplistic to figure out what the next best mod would be, and it doesn't cover things that are not intrinsically linked to power gains. |

Its a tough thing to do since everyone is testing under diffrent conditions and using diffrent dynos. That and the stock ecu is extremly fiesty.
Part X might make Y power on one day and then you go to lunch and now its making A power. Without a stable tune and testing parts on a average of 5-10 times each itll be really tough to get accurate numbers for what each part really makes. Regardless right now bang for buck will be a tune apparantly followed by the nameless axleback/downpipe/overpipe system. The header when ever its released will be a amazing bang for your dollar but thats not currently avaliable. Intakes dont seem to be worth it without a tune but they are cheap and if you get tuned down the line i could see them being worth it. The perrin system with a tune does great things to the torque dip and really helps all around the powerband. Of course this is all personal opinion, but i think full bolt ons and a tune will easily make this a quick car compared to stock. |

From looking at Perrin's post: http://www.ft86club.com/forums/showthread.php?t=13991.
They made 18WHP with $2,500 in parts; PERRIN 2.5" Catback, PERRIN 2.5" Catless Front Pipe, PERRIN 2.5" Overpipe, and PERRIN Headers. That is about $138 per HP. This will not pass emissions anywhere since the cats have been removed. Now you can add the ECU and probably free up quite a few more ponies. I have not seen a dyno with the whole exhaust plus the ECU. Now if you compare that to the Accelerated turbo kit which is going for $5,800 installed and nets about 100 to 130 WHP. Not sure how much it is for the basic kit not with the ECU. Hard to find the right dyno for the base kit. But if it is 100 HP than it is $58 per HP. Now that will be you best bang other than nitrous. |

I understand everyone's concerns and point regarding different Dyno's etc etc, but something simple like jadewbj's post should help the OP.

I'm surprised we haven't seen the "obligatory" you should get driving lessons, go to autox, etc...
anyways, to answer the question, unless you go FI, any mod that you "bolt on" is going to have a marginal difference in power. you're best bet is to determine whether you are going to stay NA or go FI, once you decide that then you can set a plan of action. it might also help if you give us a price range... |

Your best bet for added WHP at this point seems to be to choose your favorite full exhaust system (full header back - AP, Agency Power, Nameless, SRT, whatever) and get a tune (Visconti ECUflash is proven at this point).
Pulleys, intakes and partial exhausts don't seem to do much in isolation that wouldn't lie outside the range of dyno or weather fluctuation. Not against 'feel' mods per say - this car is all about feel. I've added stickier tires, better pads, a sound tube delete, a meatier shift knob and a Nameless track pipe so far and the car 'feels' a whole ton better. Faster in corners, stops better, feels better to drive. More power though? Nah. The proven options for adding proven WHP are pretty few but pretty straightforward at this point.

According to Don in his post: http://www.ft86club.com/forums/showt...=9942&page=101 Quote:
If it is 290HP with just the $5745 (includes installation) then you are talking about $20 per WHP which is crazy cheap. FIXED: As pointed out below it is a 130WHP gain for $5745 or $44 per HP. People can argue all they want about comparing different dynos, cars, locations testing procedures but the best bang for you buck is turbo (I am ruling out nitrous because these are not drag cars). Making power with NA cars without adding Forced induction is always expensive. Think about it, 18WHP with $2,500 in parts; PERRIN 2.5" Catback, PERRIN 2.5" Catless Front Pipe, PERRIN 2.5" Overpipe, and PERRIN Headers. Even if you add a intake and a tune you would be lucky to net 50WHP. That would also end up costing you around $4,000 give or take depending on which parts you choose. Edit: That would make it about $80 per WHP for NA Mods. Gotta pay to play. Last edited by jadewbj; 08-17-2012 at 10:52 AM. |
