Hey everybody, Im from Minnesota.. I swaped my single overhead vtec motor to a JDM B18C(GSR) motor with LSD. Anyways, I have all the basic bolt ons you can think of...(coldair intake, header, catback exhaust, intake manifold, cam gears, ctr intake cam, single underdrive crank pulley, fuel rail & regulator, clutch & flywheel)
I've been to the track a few times and I run consistant 15.1 & 15.2. My best run ever was 15.0. which is about the same time that a B16 hatch would do here in Minnesota.
Anyways, I just got my car dyno'd yesterday, and the results sure didn't satisfy me a bit at all..!!! Not even close to a STOCK USDM GSR(around 150whp). Being that my motor is JDM it should had been pushing around 160whp, I only made 134.6 whp and 111.7 tq. Something is majorly wrong here..!!! I think im losing compression. Anyways, after tuning my motor a little with the VAFC my hp went up to 149.7whp and 118.2 tq. But what questions me is, HOW was I able to pull 15.0 with only 134.6 whp in my 93 Civic 4dr??? I don't think these numbers add up.. Please post me some feedbacks on what you guys think..

 

What size tires are you using? What's your Alt? How warm was it when you dyno'ed/ran @ the track?

Just a CTR intake cam?

 

i think something is seriously wrong with your motor. perhaps loss of compression is the bug in your motor. do a compression test and find out.....i had almost the same set up (minus flywheel and intake manny) and pulled out 165 whp and 118tq on a B16A2....so your numbers are hurting big time....a friends USDM gsr with your set up made a hair under 180.
your numbers on your dyno seem super low....but i dont think your times with the power and torque your making are not too off. i'm here in so cal...and witness a completely stock 00si pull 15.2's all day...
just my 2 cents...
good luck on your motor tho..hope its not hurting

 

Im running on 205/50/15 series tires on si rims.. Id say it was about 80-90 degrees here when I ran at the track..with really high humidity.. When I did my dyno, It was probably in the 70's.
My friend dyno'd the same day too.. in a VX hatch with a single cam vtec swap. He pushed out 124whp and 98tq. He ran at the track with a time of 15.4 on street tires and 14.9 on slicks. With 55 shot nitrous he ran 13.8.

 

ran on dynojet or dynopack?

 

ran on dyno jet

 

i've heard of people putting out bad numbers, and it was all attributed to a bad cat. have you changed it since you have modded your b18c? you might want to check it if you haven't. my friend lost 15-20whp while using an old cat on his car. holla

 

Have you checked your ignition timing. So many times after a swap, even shops, I find that people have just put the distributor on and not bothered to reset ignition timing. That can make a world of difference...

im running on an aftermarket highflow cat with the aem catback exhaust sytem.

 

i did the swap myself... timing was off the first time when i put in the unorthodox crank pulley, but was fixed when i did the aem camgears.. but i don't remeber for sure if the distributor was in the correct marking when i did the timing on the crank pulley.. it might just be the problem.. i'll check it out and get back to you guys.. thanks.

 

 

do you have any cam gears? w/the stock gsr ex cam and the ctr intake cam on stock gears you may be loosing there.. i have never worked w/a gsr that had that combo of cams. sounds kinda odd to me.

 

hey bro so you finallay tuned it. do you remeber me? glad to see you finally found your way to this awesome site.

there are about 15 people from mn here and about 5 of us hmong pepes. Holla back yo! I think i still have your cell#


BTW damn bro your GSR only baseline dynoed at 136?... has to of been the timing. YES with 136whp that mean your baiscally dishing out only about 155hp to the crank and 15.1s are what I would of expected.

Stock 99si B16 dyno at like 138 to 144whp.... they weight more than your car and they run 15.8 to 16.1s at rock falls. So if you look at the math it does seem to ad up just fine. I though your motors timing was really off and motor seemed to be a little shakey when i saw it.

 

have aem adjustable cam gears with ctr intake cam and stock gsr exhaust cam.

 

yo wassup.. yeah, i remember you.. anyways, yeah i think it is my timing thats the problem.. sometimes my car just dies when its in neutral.. but this has only happened since i had put in the ctr cam. imma get it checked out as soon as i can find a timing gun. anyways, i took the 70mm ericks racing throttlebody off.. imma be selling it.. let me know if you know anybody that might be interested in it.. just give me a reasonable offer.. if not then imma let my cuz'n use it.. he's got an ls/vtec setup coming up.. hopefully it'll be ready for the last rockfalls in october.. hopefull my z6 crx would be ready too.. alrite.. later..

id say line up all you timing marks and put the stock pully on and check your timing marks. the last couple unorthodox pullys i put on didnt line up with the marks on the timing cover by the crank. if you lined that mark up with the unorthodox pully theres a good chance your timing is off.

 

putting the stock pulley back on is what im thinking about... i can't stand this freaken minnesota weather over here anymore... im thinking about putting ac back in my car..

dude don't wimp out... AC is overated. .. MN winter is just a few months away.
haha good thing you know who I am... you should... were cousins.

I know you will get into the 14.8 range next time you go to the track just get some slicks. I could of swore i told you that you did not need that 70mm tb... only high compression motors with wild cams would see any benfites form it. Stick with an ITR 62mm and you'll be happy. I still have your cell#, I'll give you a call soon. i work like 85 hours a week so i have no time for anything. THANK GOD that I work at a station that give me the leisture of online access anytime. LOL

I had some CTR cams that i just sold. I could of sold the exhust side for you for cheap but... oh well. Damn we nee to meet up agian...... are you going to rock falls in 9-27-03?

BTW i got my motor bro

 

i went to rockfalls this past weekend thinking the dyno with the vafc would do a little difference to my time... but i guess it didn't do much.. i also ran with my frenz slicks.. but i think they were too small for my car. still running the same timeslips.. anyways, i might go to this next rockfalls but i don't think imma run unless i get my timing checked.. my fren is gonna be squeez'n 75 shot this time hoping to maybe run low 13's to high 12's. he ran a 13.8 with 55 shot. if i go then i'll see you there..

oh yeah, my cell is fucked up.. so i don't think you'll be able to reach me on my cell.

late..

 

yo man ur car must be really ******* up i have a 2000 civic si with b18c gsr in it with lsd. i advanced my tuning and i lightened my car up i ran with shitty as tires on the track. i had air intake and stock civic exhaust with stock cat and i ran 14.95.
check ur compression it really should be at 10.6.1
stock gsr is at 10.1

What was your MPH in the 1/4 mile? I ran a 14.9 @92.75 MPH with my B18C. I am taking it to the shop for a compression and leakdown check in about 10 min. I will let you know what happens.

 

Found my problem maby it will help.

I had it dynoed and found it has 142whp but it it running stupid rich so I ordred a VAFC and will have it tuned on Monday

 

my friend with a stock ls in a 2dr coupe ran a 15.2 so i say you're about right

 

Just dynoed my b18c1 in 95 ex with dc 4-1 stainless steel header, high flow cat, apexi n1 catback, and short ram at the dyno not tuned yet for baseline and was a little upset with 145.25hp and 113.37tq. I was expecting around 155hp and 120tq.. am i wrong or what? What do you guys think?
