yeah, i'd say that's a pretty nasty dip right there. Listen to those dudes and get some cam gears and something to adjust the A/F.

 

I would be willing to bet that when the head gasket was installed the vacuum lines for the secondary iab's were hooked up wrong. They are staying open all the time. This causes a dip when vtec comes on. The only reason the gsr motor activates vtec earlier than the type r/ b16 is because it works with the dual runner manifold. Check this....Go look at your engine bay and make note of the position of the iab actuator arm coming out of the diaphram. Now, start the car. The arm should move up, closing the butterflies. Rev the car to 5700rpm. The arm should move down, opening the butterflies. If it doesn't do this.....well, your welcome

 

I checked the iab thingy....Its a round brass colored disk with an arm at the bottom right on the drivers side next to the intake manafold, right? Well, if what I was looking at was the iab then it is in correct configuration. Off down, On up, 5800ish rpm's down. Soo i guess we're back to the cam gears and vafc.

WTF is up with the 5 posts per 24 hours. I have a legit problem and Im not a post *****.

do a compression check. My b16 on 8psi pulled a 188fwh and it should of pulled a stock 220fwh. checked compression and I had 2 broken ring lands. Try a leak down also. This first to see if the motor is good, mileage doesn't matter when boost is involved.

 

Baha is that guy with the ZC bragging?? He makes peak horsepower ar 4500 rpm??? He needs more tuning bah

 

OMG you neeg glasses

Yeah the problem probably is these bottles of beer I have in front me instead of glasses.. I make 196whp out of my zc sohc at 10psi was the reason for the comment though.

 

what is your set up?

 

I've only had the turbo on for a week. Can you check for broken ring lands just by doing a compression test? BTW I keep throwing an 1 O2 CEL.

Bottoz

 

what is your set up?

---------------------------------
Stock zc sohc, equal length custom manifold, IHIVF8 turbo, 2 inch mandrel bent intercooler piping starion front mount, 2.5 inch exhaust from turbo back no Cataytic, piggy back chip that runs 3 extra injectors and retard timing to suit... That about it really most parts are HPC coated..

Bottoz if you had check light on whilst on the dyno then that will be your problem. Other then that have got a decent exhaust and hi flow cat???

 

The check engine was cause I was running too rich. I had to drive about an hour to the Dyno in Denver. While I was there they did a pull with VTEC disabled. The graph looked very normal...no dips/spikes or anything abnormal, just lower numbers.

Why use a thicker headgasket to run 8psi????

 

You're in Aurora huh? I got my car dynoed at the same place.

 

That's what I want to know. I know they supplied it and everything, but you really didn't need it. I'd say it's your vtec also.

 

why not go with the stock head gasket for right now until he can afford a standalone and cam gears? i know a noobish ques.. go with a stand alone, just alittle more money but a world of difference, plus it'll help save your motor

 

If you have a CEL, the first thing you need to do is find out what it is. You cant just guess and assume its due to your car running rich. And is the check engine light on all the time, or was it just at the dyno?

Brian

 

Yep!! Also, you do know that running too rich will screw your motor up also.

 

Did you ever get that thing figured out B? If you still need help with it let me know, I have been fixing a lot of weird ones lately. Maybe i can put my brain on it and get it tuned for you.

SOmething's sick sick sick on that GSR, My Eagle rods/9:1 Endyne pistons B16a put down 180 ft pounds at 4k and it's still just a .010 over 1595cc engine!

[TF&TF]You've got a nasty hole in your timing curve. Just adjust the cams, change VTEC, and get it straightened out, and you'll run 9's![/TF&TF]

 

I got my AEM adjustable Cam Gears in Yesterday. I'll be installing and Re-Dyno tuning this Friday the 10th. If its still nasty after that, I'll just buy the VAFC at the shop, have them put it in and keep trying. Look for more Dyno Graphs on Friday Afternoon. Hopefully it will put me to the 230hp/200tq mark.

Bottoz

 

Sell the Cam gears.
Don't buy the VAFC.

but Injectors and Hondata. Then get it tuned. Problem solved.

 

Ok, Buy me injectors and a Hondata. Im getting plenty of fuel. I'll pass on the injectors...for now. Oh, and I see that you have STR Adjustable Cam Gears...How about you jsut sell yours. And, 1st post...It was tuned...for 3 1/2 hours on the dyno. It was determined that Cam gears was needed. Thanks.

Bottoz

 

You can buy Hondata ($450) for a little more then you're about to spend on the VAFC.
Plus for a little more you can by some DSM 450cc Injectors ($100) and a Resistor box with clips ($40)

I've seen numerous of dyno sheets of turbocharged b18c motor's. None of them looked like yours. None of them had cam gears.
Hondata and a good tuner will get you results like this.


* Stock GSR engine and gearbox
* Turbocharged and intercooled with 10 lbs boost
* HKS Boost controller
* Stock fuel pump
* Hondata Stage 2b engine computer upgrade
* Erick's Racing fuel pressure regulator
* RC 440 injectors

Yes I have Cam gears. But after I installed the Hondata I took them off and I'm now selling them.

 

Well, thats 600 bucks (on the low side) not including install time/money and tuning time/money. Or, I can spend 180 for the gears and 1 hour of dyno/tuning time. I know my graph is screwed, but I have full confidence in the guys doing the dyno/tuning. They have a 433hp/306tq hatch built and tuned by them. http://www.dynopro.com/mhhr_detail.asp?ID=313. Soo we'll see on friday if the gears fix it.

Bottoz

 

Well either way. Good luck with it. I hope you get everything worked out.
