so before anyone dispute this i have the numbers to show! The numbers are corrected and are dyno jet numbers.
it was a hot day...like 90F give or take a few...shop is in pompano beach...there were many runs...before i go to my numbers please read..or just skip and go to the numbers...whatever
Anyway...a bunch of us went....3 Si...1 gt mustang...cobalt SS....srt-4
My mods are on my car domain and in my profile.
Other 2 Si...
1 bone stock!
1 SRI/DC e/elminated cat but stock header,hondata img
GT Stang...Stock but has a computer programmer thingy
cobalt SS...smaller supercharger pulleys, computer thingy
srt4....stock with mopar CAI
numbers for the above are:
-GT stang posted a 195-198whp can't remember tq numbers...right on according to the manufacturer of the computer program module
-Cobalt SS posted 234-238whp...again can't remember tq numbers
-SRT-4 posted 228 on his first pull....can't remember tq number...but it was spot on to another srt-4 that dynoed his car at another shop on a different dyno with the same mod...by the way that guy has a stage 3 going on in the coming week.
Now for the Si..
bone stock Si made 3 runs like all the rest....
first run was...
now the second and third run he romoves the air filter and uncovered the box and he posted a 193HP and can't remember tq numbers on the second...on the third ran 199whp!!!! and almost 150tq but his car leaned out some the tech guy said and his car cooled down a bit so that made power for him..but everyone over there was absolutley shocked!!!!RSX owner was over there and couldn't believe it...but he said his car dyno's there and the numbers are correct...cuz he also dyno's elsewhere and get the same numbers as he does in that shop. his rsx by the way is very fast...has a huge turbo etc etc...anyway here is the bone stock Si's other chart...show's all 3 runs...
Other Si(gil/954k20) with eliminated cat but stock header, dc exhaust, SRI and IMG went like this...
1st pull....198. something whp
2nd pull.....199-200 i think it was
3rd pull.....201. something and 150 tq...he has his own post so u can check that our for exact numbers
problem with his car though was that he was running very lean and could not get any at the top...i don't have his charts...sorry...but if he can tune for that he'll make more...
My Si was running rich...i only have one chart that shows the AFR...but the others were even higher...guy said i'd get a lot more if i could tune the AFR and so on...looking up for me... anyway check my profile. or my cardomain for my mods...I only have the chart for my 1st 2 pulls....i'll explain my third pull after...
1st pull...shows HP and AFR
2nd pull....HP and Tq...
3rd pull.....this pull was even stronger than the second...the curve was higher than the second from the bottom all the way to the top but then the car began to run rich as it went near the top it went flat and the numbers were right in between the first and the second run...the guy didn't give me my third pull...looked like i would have hit 205 but then it went flat right about 198-199. anyway if there is a way to tune for that right now let me know!!
That being said...the Si is more capable than any of us thought and responds well to mods if done right...if done right cuz look how the first 2 ran lean especially Gil, who eliminated his cat(real lean),bear was kinda lean but kinda rich also, and myself who was running real rich...but we'll get to where it's ideal eventually...i'll post the other charts for all the other cars when i can get them in my hands...
AEM CAI has been said to cause a hesitation/bogging about 4000 rpm give or take by hondata and others...it was noticable in the charts...wish i had them to show...anyway this is caused by a fluctuation in the reading of the MAF sensor....it's not getting proper readings because of turbulent airflow...so the car can run lean or rich in my case it kept running rich...seems so for every other person who has it...
another stock unbroken in Si ran 180whp and a can remember tq numbers.
check urbanracer.com for that.
all Si pulls and cobalt pull were 4th gear pulls....dont sure of the other cars...mustang was an auto!
now for those of you who dispute the numbers...i'd like for u to take me to a dyno of your choice and i will pay to prove to you that the numbers are correct..PM me whatever and we can do it...i feel confident that they are correct cuz a number of people were there and backed up the shop, dyno and numbers....the stock Si's dyno was very strange but after he removed the filter etc, leaned out etc...but i'll go to a dyno of ur choice and pay just to prove all numbers are correct...Si along with other cars.
so now let the wars start....
