C'mon now! Be a little more optimistic sdhotwn.
Buschur Racing dyno'd their intake, testpipe, and catback, I believe, and it gained 8 whp. Granted, your point is still valid about a catback providing the real hp gains compared to an axleback, but I would be willing to go out on a limb and say an axleback provides at least 2-3 whp.

 

I guess typically people are concerned about gains because they want to race or compete or something... therefore I always estimate conservative unless there are dyno results to say otherwise.

The Buschur thing I think was with the intake and the catback etc... but yeah they got 8 hp... so I guess you may be right on the 2-3... but I'll stay nearer to two

Later!.

 

Yeah but the money to HP ratio is just horrible!!!!!!!!!
10Testpipe 50
2)Catback 375
3) Intake 160
Thats 585 bones for 8hp at the wheel...no offense anyone but that is just absurd. Thats about 73 per hp!!!!! Think about it guys!!!

 

On a 4 cylinder... anything under 100 per horse is somewhat reasonable in the long run... just is the way it goes... Turbos run about 4.5G's intercooled and you are probably talking 80 horse... so about 56 dollars per horse.

Maybe I'm just wrong in thinking that 100 per horse is reasonable for a 4 cylinder. this isn't a 6 cyl or an 8 cyle where horsepower doesn't cost much...

How much horse did you get out of your eclipse? and how much money did you spend? Also keep in mind that upgrading a Lancer is just plain expensive because the parts aren't common like a Honda or anything. Also keep in mind that if it is your hobby and something you do for fun... then there isn't really a price... i know people that blow a 100 bucks in a night easy out drinking... 100 bucks per buzz?!? howz that?

Later.

 

ohh well i love my lancer well get parts!

 

Yeah I see where you are coming from but look where I am coming from. I don't want to go all out in detail but here is a simple example. I'm low balling here......1 PSi is about equal to 7hp right? A manual boost controller....I paid $45 for from Boostcontollers.com. The 2g's come stock with a crappy plastic BOV thats leaks above 11 psi. So what did I do, went out and got me a lovely 1g BOV for $130 (the extra $40 I had to pay is because at the time I had not upgraded my upper I/C pipe and needed to buy the adapter flange. Normal price is about $90.) So then I was able to raise the boost to 14., 3psi over stock. So that is equal to about, lowballing again here: lets just say 10hp. So the cost to hp ratio would be 17.50 vs your 73. And remember I am being very consertive with the actual hp gains. You are always going to have to spend alot more to get power out of a N/A car. I was just speaking from my viewpoint. To me that is alot of money for a minimal gain.

 

Also to note that the ratios change the farther you are along your upgrade path. My turbo supports up to 350 hp but I am by no means near this. I need a few more things like bigger injectors AFC, bigger fuel pump (current pump is rewired), down pipe, test pipe or high flow cat just to name a few things. I could also use some porting. But the case still stands what you pay per horse power, I will always pay way less for gains than what you pay. The same goes for bigger 6 and 8 cyclinder N/A engines. They may have alot of room to grow over a 4 banger but F/I is always going to be cheaper upgrading when built F/I from the factory.

 

Yeah, but the point is that comparing gains on an NA setup versus a turbo setup is an apples vs oranges debate. There's no sense comparing the two because any gains are obviously felt greater when you've got forced induction in play.

 

Yeah but "the point was" as you put it, we were comparing cost not gains. I just said that much money for that much horsepower is absurd, from my viewpoint.

 

true, but he was also asking about a test pipe, right? That would lose torque. But yeah, a good intake and aftermarket 2 1/4 inch exhaust will increase both torque and hp.

And btw, there are quite a few exhausts available for our Lancers, now. everything from ebay $hit to Greddy.

 

sure they do, there are 3-4 that i know of. JIC makes 2 full cat back, Buschur makes one, Greddy makes one, Thermal R&D make one. I am sure there may be more, but i am no expert

 

i meant a full exhaust system with all the piping! tahnks though i ma going to probably go with the greddy!

 

Actually, the original question wasn't even about hp per dollar to begin with:

I just think it's completely pointless to even bring up any turbo numbers, seeing as how the question was regarding an NA setup and gains relative to an NA setup, not a turbo setup and the related gains.

 

I thought that was what a cat-back is? Unless you want something with headers and a cat too

 

i think it am just to tired here at work sorry i was just for some reason blubbering i meant a full like down pipe back i think! thanks
