if you could get a scan or pic imapunkclaimer, that would be cool. definately wanna see the torque and hp curve.

it seems as though the RRM piggyback/reflash gives peak torque in the first "hump" early but has a not so different second "hump" than most other lancers. also, it doesn't seem like 03lancer's dyno follows the hp=(rpm*tq)/5252 formula either unless i'm reading it wrong. kinda makes me about that peak hp of 127.

imapunkclaimer's dyno compared to urbanknight's dyno would give quite a definitive answer between the difference of a cai and sri.

 

im going to attach 3 pics because i had to take it with a webcam. i dont have a scanner.

1:

 

2. here you can see the hp 115.5

 

wow is that one ****ty powerband!!!

 

3. and lastly, the torque loss at the critical 4k rpms

out of the 3 pulls, they all had this dip.

 

Are you getting your PB retuned?

WADAD

 

yea, but friday i have work so maybe next week on monday

 

Sorry to follow up with another question but did you ever say what kind of dyno it was?

WADAD

 

dynojet at xs-engineering

 

what are the numbers on the right and left? i can't read them. that drop at 4k might be exaggerated but still correct depending the on the units the graphs are using. it looks like a regular torque curve except stretched up and down. there is expected to be a drop in torque at 4k. can you list the numbers on the sides of the graph at each line?

 

Was the dip a shift point? Looks logical?

 

you dont shift in a 3rd gear pull. thats the full band in 3rd gear from 1.7k rpms to about 6k rpms.

the units go from 126 then drop to 110 then back up to 125 all within 1k rpms.

 

in that case, dropping to about 110 is expected. the lines are spaced out too much and it looks like a big drop when actually it's normal.

your torque curve is better than mine with just a cai and PB. i've got all sorts of **** in my car and it's barely close to yours.

(time to save up for an emanage )

 

I had only a slight dip in torque, wondering why yours was larger? But the numbers look about right. Piggyback is supposed to be an improvement from the reflash, and people say CAI has more hp than SRI. If it wasn't for someone telling me that CAI has a sluggish throttle response, I might switch.

WADAD should I tell RPW to give you a commission when I buy the header? Actually, I wanna see if the RRM header produces the same gains (yeah, I'm a loyal customer, they take care of me). Are they constructed in similar styles?

I did my pull on 16x7 19 lb rims with Falken Azenis tires. I figure, the 4 extra pounds balances out the smaller diameter, so still a pretty accurate figure. Not sure if the car's weight makes much difference in dyno results, as the car is stationary and not propelling itself or overcoming drag or anything like that. But I put 2700, as I believe Mitsu states 2701 as the OZ curb weight.

Oh yeah, here's my 1/4 mile times with the same setup
17.268 @ 79.52 mph
Should I be posting all this in my sig like everyone else?
But what really matters to me is that I beat an STI by 1.5 seconds at an autocross in October!!!

 

You gotta keep in mind that dynos are not always accurate. Obviously I dynoed out MUCH lower than most people on here.. and WADAD dynoed out pretty darn high. It is possible we both dynoed on crappy dynos. So basing a decision off of either of our dynos is a VERY bad idea. If WADAD goes to another dyno and gets the same number THEN you have something. If I go and dyno my car on a different dyno (which I can't do now as it's for sale) and it shows 120 now or something because I use a different dyno and I have the Kamikaze header, do you really think that my header gave me 30 hp???
