Anyone out ther running Skunk2 stage 1's in their GSR? If yes...
Any problems?
Running lean in VTEC?
What other mods do you have?
Have you tuned them yet? What kind of gains?

Please respond if you have these cams.

Thanks.

B18C5 with Skunk2 Stage 1 cams , VTEC at 5600 rpm, leaned down fuel controller settings, FPR 52 psi @WOT, 11.3CR, Comptech Icebox, Toda header, 2.5 in. exhaust system (testpipe) in blue, Exhaust removed in red. 200 peak whp.

B18C1, Skunk2 Stage 1 cams , VTEC at 5000 rpm, AEM CAI, Skunk2 IM, full SMSP 2.5 in. OD exhaust system:

Mike, are those before or after tuning?

MD rocks

 

[JustinKlemgold]

What I'm seeing is the GSR is about even with the TypeR....am I seeing correctly?

 

[Edubb]

those are really good numbers.. it makes me concerned about my setup.:

b20 block
b16 head
approx 11.3:1 compression (JE12.5:1 + thicker HG to lower)
skunk2 stg1
rc 310's
hondata st 2
vafc
cam gears,
iceman intake
greddy 4-2-1 w/ IB custom 2.5" collector
carsound 2.5" cat
apexi WS 2.5" exhaust.
fully tuned by jeff at IB

and i only mustered 187hp 138 tq peak.
and the midrange is lower than both those 2

i have a dyno but no way to post. if i can email it
to someone to post let me know.

lose the header...

 

[Edubb]

hehe, already on top of the shopping list. i know that my output is hindered by it but how much hp tq would it actually free up? my numbers are significantly lower than both examples and i am running hi comp/ 2.0 whereas
they are stock bottom ends. i would think that my low to midrange would annihilate(sp) the 1.8's (especially torque) and the top end would be pretty close.

i also kno that a 2.0 is a big breather and in and out is pretty important..

The exhaust system I think is messing with your numbers. The Greddy header is of course inadequate as you know and the Apexi WS a 60mm (2.36") exhaust so it's not matching up very well. What model number is your Carsound cat?

Send me your chart and I'll host it so we can take a look at it.

 

[MichaelDelaney]

get a 64-65mm tb and portmatch the im.

 

[azn6q]

was that B18C1 runnin an OBD1 computer? I have a 98 gsr, skunk 2 stage 1, aem cam gears, aem cai, dc jdm 4-1 header, high flow carsound cat, and tanabe racing medallion, a stillen fuel pressure reg, all fully tuned by import builders and i only managed to get 158 whp peak. i have a dyno somewhere around here, i gotta look for it. i'll post once i find it

 

[MichaelDelaney]

most people can get 158 whp with just i/h/e (and a stock cat) ! yes...even with the hyped supposedly disadvantaged OBD2 ( of course that's a myth..OBD2 is not a disadvantage).

what is wrong with your engine?

 

[azn6q]

someone told me its because of my OBD2 ecu, but i dont really know. ive seen a dyno of a stock 1998 gsr at www.bseries.net and it only managed 133 whp, while the previous years managed to pull 146 whp peak. will going OBD1 really make a big difference? have any suggestions on what i should do to be getting the power i should be making?

 

[BlackGSR]

people usually go OBD1 to get rid of a lot of codes that their obd2 computers surface. A lot of times those codes can make the car run weird

 

[azn6q]

weird like making it slower or somethin?

 

[Edubb]

hmm. i dont know that number on the carsound..jeff just grabbed it from the back room, he also said that my exhaust was 2.5". i didnt think that it was but i didnt argue with him. maybe i dont even have a 2.5" cat! makes me wonder now...

[ToDa003]

was it round? or oval...

i'm sure u have a 2.5 cat

What sys are you using to modify your fuel/rpm points? (vafc, hondata, ...) You have the setup I was going for so I'm interested in the details of what you're doing.

 

[EverReady]

azn6q: if you are throwing codes then your A/F ratio might not be optimal, depending on the codes, which will effect tuning and power.

Edubb: I dont see that you were running a diff. IM?? The dyno of the B18C1 was running a Skunk2 IM. Changing the header, getting a new TB and a new IM would probably free up some good hp for you, or is this not correct?
