Took my 04 to the dyno yesterday

you know this guy is smarter than 90% of the people on this forum, right?

why would you argue about his daily beater setup and his ability to make power with the 3800?
 


Because my neighbor's brother's cousin's cell mate put headers on his '86 IROC-Z before he got thrown in the state pen. He put like 10 cars on an 82 civic one night on main street.

Moral of the story, if you don't have headers, it's impossible to make power.

Because, exhaust manifolds are not a restriction. The car is having no trouble getting the air out. I don't understand where you are getting this idea.

No way you will see 400whp without an IC. I'm guessing with some race gas, pulley, and injectors, the car would maybe make 350.

Anyways first pull with the stock airbox:

264hp and 275ish tq

Pulled that off, and stuck a filter on the MAF for the second pull:

266hp and 278tq

It was still running pretty rich, but almost a dead even afr across the board, so I changed my base PE table from 11.1 to 11.3. And, for whatever reason, it went ran richer. Most of the pull was ~10.9afr.

259hp and I don't remember the tq.

After what the car made already are you saying your going to gain almost 90 hp with just injectors pulley and race gas?
Race gas would make less sense than other mods if you plan to keep it your daily driver..........
Might as well just use nitrous and pump gas in that case.

Race gas would be for ego stroking dyno numbers/track times only. You really think I would daily drive it while paying $8 a gallon for fuel? HAHA.
 


Now your assuming I said something about as much as Bio.......
Obviously I know you dont run race gas in a daily driver guy thats why I said might as well use nitrous and pump gas........

I lost you. What does using nitrous and pump gas have to do with race gas on a few dyno pulls?
 
Im not pissing in your thread, I just think you could get more from that cam and out of that car. (while still being reasonable, also is it safe to assume this transmission is stock?)

Now the race gas comment I just meant that it would be more cost effective to just use nitrous and pump gas because as you've stated before its a daily so obviously there is no need to run expensive race gas other than yes maybe for a ego stroke or some big dyno pulls.

Anyway I still look forward to see what you could pick up with the pulley and injectors. Even without adding race gas so you could see what the injectors and pulley would make vs the dyno numbers you already posted.
 




Why would you compare a car that is running on E85 to a car that is running 89 octane fuel?

I don't think you are understanding what actually increases torque on these motors.

Last I checked E85 IS pump gas................

As for me not understanding what makes torque well we all know throwing in a xpz cam and leaving everything else stock besides the self ported heads doesn't increase tq very much either.........

I never said it wasn't. I was asking why you wanted to compare a car that is running E85 to one that is running 89 octane. ?

So, in your opinion, what would increase torque?
 
Keeping manifolds gives it the factory low-end torque curve.

Unlike headers...that sure, you might see gains from...but it's up top.

Not as useable on the street.

Magic and straight pipes apply.

I over-guessed a little bit. Not too bad of numbers from a stock pulley/injectors...with a cam/heads/DP. It'll really pick up some power up top IMO when you swap injectors...especially if you said they were running static @ 5100~.

Only thing I wouldn't do again is run a double roller...I killed the gear on mine...probably due to stupid low idle speed....but I'd just run a stock chain + some 130's and a higher idle next round.
