um well thats kinda hard to base ET's.....i mean weather for one, plays an important role of your trips to the track.....you need some tuning...

Yeah, there is much more to it then 2 time slips, there are sooo many variables that play a part in it. How does the car feel compared to before the install?

chingchong

before the installion the car pull hard but now it is laggish

i know you've probably heard this a million times...but get that thing on a dyno

I have the SAME problem. People are telling me 2 different things.

1. I need a Fuel Pressure Regulator and bump the pressure up.

2. The cam timing is off by a tooth.

Up to 5000rpm, its alright, but in Vtec it LAGS like hell. Takes DAYS to get up to Redline. Definately something wrong. Shop said its because the cams are big and not enough Fuel Pressure for the higher Rpms. The other group says its the Cam timing and that its probly off by a tooth.


DAMN it! I have no idea what the problem is...

chingchong

that is the exact thing that is happening to. my timing is not off. i do have a fuel regulator but how much should i put it up to? im at 41 psi

B00ST2nR

The shop said 52-54 is what Skunk2 recommended. Try that out and tell me how it runs.

B00ST2nR

here's the details of my car right now.

Car: 2000 Integra GS-R


Modifications:

Skunk2 Stage 1 Cams
Skunk2 Cam Gears (set to 0,0 right now)
AEM CAI
DC 4-1 Header
VAFC - 5200rpm Vtec X-over

Stock Fuel Pressure is at 38? 40?

Shop said I need it close to 52-54.

your name offends me

Try moving up the vtec cross-over point to 5700 or 6000. This should help you out.

o_Rage_o

try 5200-5400 first but def good direction to try.

who. mine?

I am going to be installing stage 1 cams, cam gears, and the ITR valve train this Monday. I do not have all the electronic goodies to go with the cams because my first priority was getting the parts in because I'm going back to school in a few weeks. Is this a common problem? From what I have read the car should run on the rich side from the factory so there should be plenty of fuel available without upping the pressure. I plan on getting an DC JDM 4-1 header, VAFC, and FPR before heading to the dyno. Am I probably going to be losing power in the mean time?

PYITR821

I wouldn't expect any big horsepower gains until you buy that VAFC, FPR and then hit the dyno. You might even lose some power. I would take it easy after putting the cams in until you get it dynoed. Good luck.

pistol

I'll tell my foot...but I don't think it will listen. I am just hopping to see at least a small gain until I can get the rest of my parts.

I have the Skunk2 Stage 2 cams, with no FPR, but I do have a VFAC..I love it...Pulls nice til about 6, then takes off...VTEC crossover at 5700..Cams set at 0,0..Going to get it chipped and dynoed at a differeent place...Waiting for MORE power!!!

chingchong

i guess i need to get a vfac. i tried putting more fuel but the check engine light comes on.

B00ST2nR

ok. Just got back from the shop and we checked it out and it wasn't off a tooth. It was Straight. So that's not the problem...

I kicked up the Vtec X-over point to 5700rpm and its a bit better.

I can feel my car pull better from 3000rpm - 5700rpm compared to my stock cams, but in Vtec, it just kind's of hesitates. Not by alot, but it doesn't shoot up like its suppose to. We're gonna try to get an FPR in and up the Pressure on Monday and see if it pulls in Vtec like its suppose to.

Cam gears are still at 0, 0 but we might try +2 and -2 and see if its any better. Crossing finger* Hope it works and runs strong when its done.


After the FPR and if it STILL doesn't solve the problem, we're gonna take apart the motor and check closely again. Anyone know what the problem might be? Any tips or tidbits you guys wanna share?

neo1z

this all sounds wrong --- im sure the fuel would help, but the skunk2 stage 1's are supposed to be a drop in 8-11 whp, and a tuned 17-19 whp....you should NOT be running slower if you installed the cams and gears correctly.

chingchong

keep us posted on what happen.

B00ST2nR

I know and thats why I'm so dissapointed and frustrated!!

LOwrestling2001

dont listen to drop in **** tha'ts bullshit, well not entirely, u will lose it somewhere and gain it elsewhere...as opposed to ITR cams, which are drop in and u get gains no losses at least not noticeable. Skunk2nr, i really doubt it's an FPR go ahead and try, but my friend that dropped them in didn't have that problem. another friend of mine had the same prob w toda B's ,...but became happy when it got tuned so just go get it tuned. u mite not need an FPR...but it helps.

B00ST2nR

What's Skunk2's recommendation for the Cam Gear timing? Intake +2, Exhaust 0?

chingchong

yea that is what skunk said on this paper that comes with the cams, i think that this i before tuning.
