Well, the car made a 12.7 pass in a full interior 2558 w/driver EK hatch and about 214/154 on a partial tune. So I decided to retune fuel and cam gears to see where I can go. The setup is:
85x89 sleeved GSR block
Skunk2 Pro IM
Skunk2 Stage2 cams
Skunk2 Pro cam gears
Hondata IM gasket
Supertech valvetrain
CP 11.9:1 Pistons
Eagle H-beam rods
Cosmetic headgasket
3" customs intake w/vstack
MSD 8mm wires
Hytech replica "BIG TUBE" header
STOCK B16B HEAD
Hondata S300

Here are the graphs

These were on two different days but on the same setup.
Blue: Skunk2 stage2 cams Red: Skunk2 stage3 cams

Another of sk2 vs sk3

These three are with different cam gear settings only
Blue I+2 E0 Red I+2 E-1 Green I+3 E-1

This is a side by side of my chart and a turbochared ITR
Me=blue Turbo ITR=red

One of my best pulls

 

Congrats on the new numbers.
It looks like your Hondata S300 system is making life easy for you :-)

Where did your vtec engagement end up? My guess is you have it at 5500-5600 rpms?
It looks like it can be moved around a little.

I would try adding fuel from 4800-5600 rpms & a little throughout the rpm band

Ps. There is something really messed up with that turbo itr, such as a boost leak etc.

I tried adding fuel there, up to 4% and it made little change there but changes on the upper part of the graph

That means you have sniffer delay. Try adding it 500 rpms before the dynojet is indicating the condition

 

nice numbers! lovely to see good progress..

tell me about the sniffer delay.. LOL

 

Nice job but a word of caution. 14 is lean at WOT. Trust me you will eventually crack the number 3 ring land at that A/F.

 

Wow 221 on stage two's

I agree that 14:1 is lean at WOT. Ask me how I know.

 

nice numbers you put down.

 

 

Nice numbers. I figured for the amount of work put into it and the parts you could have gotten a little more. I would have went with some Rocket Motorsport M24x cams.

 

with the forged pistons you got,what is the silicone content. some like to expand more than others depending on it,and that may be to lean

 

HAHAHAHAHAHA

w3rd!

myt cause extra heat (maybe)
over expand the pistons (maybe if 3 ring land dont crack)
and score the sleeves due to heat/overheat?

hmmmmmm

 

honestly, i've experienced my tuners afr's hold solid in the 13-13.3 area wot, yet the sniffer in the tail read 14+. sometimes it reads higher by the time it exits

Maybe one day.

 

hooking up a wideband onto the o2 bung of the header, and tuning with that, on the Djet sounds good..

 

I had an AEM wideband sensor (sensor got toasted again from race gas ) attached on the dyno the same time as the dyno sniffer, and both were giving different readings. Which one would be most accurate? The wideband is in O2 bumo and the dyno sniffer is at the end of my testpipe.

 

you have great compression and plenty of displacement... yet the stage 3's didnt wanna make more power than the stage 2's??!!!

im sitting at 12.2:1 out of an 81.5 X 89 stock sleeve GSR PRAYING for 200whp when i finish assembling it... =/
now im gonna keep the s2s2's i was gonna put in it rather then trade them for the stage 3's.


nice setup
great numbers

now spray it and go for the 11's!!

[b]EDIT:IMO im gonna say the aem uego cuz its closer... but at the same time i've had those things play games with me so many times that i cant trust them unless its a fresh sensor.
and also, on the hytech design headers, the O2 bung is in the channel of only 2 cylinders...not all four.
where as the tail pipe sniffer might be delayed, its probably reading more accurate overall..

 

Oh, I am so sorry, the wideband is in an O2 bump at the begining of the testpipe.

if u have a test pipe with an o2 bung.. having ur wideband installed there would be more accurate i think.. vs where the hytech prod. copy has it.. i think that location is for the factory narrowband sensor..

the sniffer as mentioned, has delays and subsequently sometimes alter a/f readings

 

ohhh, good choice

then to be honest... if its a fairly new sensor, id follow the uego.

how different are the readings? and are the differences consistent?

The same thing I thought. The stage 3 cams liked 34 psi fuel pressure while the stage 2's like 43 psi pressure. And this is on the same map!! The stage 3's also liked a 5300 vtec when I though they would prefer a later vtec, like 6000 rpms. I just goes to show that bigger is not always better for certain setups.

Yeap, and I've experienced it the other way too.

Either way, I stand by what I said. If he reduces the A/F by 0.5, this motor will lose what 2 maybe 3 whp.

Without EGTs in the primaries, this is all guess work anyway. 1200 miles, lol.

Unless you are going to drive around with the sniffer stuck up your *** or tailpipe. Oh, wait I just looked up some dyno numbers, and on a B series, nothing like yours I got great numbers @ 13.4-1. Must be the best.
