47-96mph in 4.281 seconds not bad



I am going to rev higher next time I should be able to hit 100mph on 3rd gear

I logged a 4th gear pull tonight and here it is. Considering afr and timing I'm really happy. Right before this I had bumped up fuel pressure while trying to get rid of idle misfires, so afr was a little rich.

ej257 pistons/rods, d25 heads, gsc 282's, ferrea springs, supertech valves
uel header, 2.5" ID uppipe, 3" dp, borla hush catback
3" ID fmic piping with a garrett IC core
id2000's, dual walbros, aeromotive fpr, perrin rails



12.5* ramping up to 15.5*
avcs solenoids unplugged
24-25psi
max egt 800c

It should pick up some good power once I fix/replace my cutout, lean it out to 11.5ish, and add some timing back in.

Jays,

You should definitely be able to add more timing past 6K. With the 35r, it easy to make the torque curve nice and flat all the way to 8k and then the horsepower just continues to climb

Nice power. Can't wait to get my car back to that power level again.

Jay can you add the boost curve to your plot. Please

I have lost two complete motors because of valve drops. The cams in this motor have even more lift than the other two, and it has higher compression as well.

Ignition timing is the 4th column from the right. My front o2 is toast so ignore that The car drives better than ever without the front o2.

HAHA I imagine the second column from the left is boost? Damn! I wish I could hold 24psi at redline.



21* of timing at redline, 26psi tapparing to 22psi , FP black IWG, 1200cc injectors, 70mm CAI, TMIC.

I know my fueling is a mess , I will have some time to smooth it out soon. I am going to pull 2* just to make it last.

Agreed. I've run 20-21 degrees up top on 93oct before. But with e85 I just threw some safe numbers in the ignition timing table as a starting point, then dialed it back a little more while tweaking fueling and boost. I had some initial problems getting boost control working right with the UTEC controlling boost.

I'll make some back to back pulls soon, increasing timing by 1* on every run.

Sounds good, I'm excited for more results. Can you pm me about this valve dropping thing, I have two motors with 282 11mm lift cams.

i don't know why you aren't able to hold 24+psi with your FP black. i am running 28psi tapering to 26psi by redline on my 8cm red, and your black should be able to do that easier than i do since your exhaust housing is bigger. at 24-22psi you are barely working that turbo. i bet you gain some nice power by upping boost just a few psi.


...and i doubt you are over MBT right now...assuming you aren't, i would leave timing where it is at...just my opinion

Interesting, what do you think i should do? Tight the IWG arm? Install a helper spring? I though you were EWG, nice .

I am also running the stock crushed BPV..

Juan you should up your wgdc a little bit from 5,500rpm to redline see if that helps hold the boost. Or buy a hallman and go hybrid boost control, it works very very well.

I have a hallman MBC, I have 3-port too but I don't like the way it feels. I am going to swap the BPV with another stock one but with the set screw mods instead of crushed.

nah i am running the original 15psi internal gate from FP. i am basically maxed out right now though. i have my WGDC set to 99.6% (stupid 16bit ecu won't let me target 100% ) above 5000rpm. i also am running an HKS bov instead of the stock one.

Juan, replace the bpv. Mine had me capped at 26 psi on my dom4. When I replaced it with the forge unit and didn't change the mbc setting I was at 32 psi. So if u change it out remember to back off the mbc a couple turns.

A bpv is one of those parts thats hard to tell if it's leaking while it's on the car. You either have to take it off and build a tester or just swap it and test it.

And t1 said that id2000 walbro + 044 should be 550-600 not 450-480

Hey, I think this is a discussion worthy of leaving in this thread, even if it is off topic.

Here is my built motor experience in summary:

1st built motor, done by a local honda tuner shop, had a cosworth cam break in half after 5-6k miles. Cosworth warrantied them. They were cosworth s2's for 04-07 STI. 2k miles later it blew a HG.

Ron @ Raw1 rebuilt that motor. 5-6k miles later it dropped a valve and game over. I was running avcs with a max value of 20 in the avcs maps. A couple people that looked at it said that the valve seat broke first, but how can you really tell after a valve head bounces all around on the combustion chamber. That motor made stupid power and went 11.0's in the quarter back to back on straight 93oct, and 10.7 @ 132 in the only racegas pass I ever made, with a blown uppipe gasket and not making good boost till the 1/8 mile marker.

Another motor went together, same cams and same basic setup except with d25 heads instead of b25 heads. After another 5k miles or so it dropped a valve and game over again. Same AVCS map.

Both of those motors had no interference when spun over with the cam gears locked all the way advanced.

So after that I said **** cosworth and **** everybody that ever made money off me and all my motors Jr helped me out A LOT with the new motor. The block was able to be saved, the rods were still good, and some of the valvetrain stuff was reusable. I replaced the cams with gsc s3's.

There are a couple good threads in the built motor section about dropped valves with big avcs cams. Almost all of them are with the cosworth s2's, but even so, I don't think the benefit of avcs is worth losing another motor.

i don't really feel like AVCS has as much benefit on the bigger turbos anyways. i mean, if you aren't catching peak tq until 5000+ rpm, and AVCS is turned off up there anyways, whats the point. obviously, there are SOME gains, but they start to lose their benefit with the bigger setups. i just don't see too much of a point if they don't really gain much. just more stuff to go wrong and cause problems IMO.

Ok thats more inline with what I was thinking. Now Im thinking Im gonna have to dual 044 it and throw an E85 safe pump in the tank to feed them or something.

My walbro 255 has been making weird noises intank. I think somethings wrong with it anyway.

I wouldn't say AVCS only has SOME benefit.... these are some impressive gains on my bros 30r...this is avcs vs NO AVCS with no other tuning adjustments.

I picked up 500-700rpm of spool going from 0* to 40* down low. That's substantial. Avcs isnt meant to provide peak hp gains up top where the cams are designed to work, avcs is to pickup tq down low where the cams arent optimized.

The problem is that on build head motors with cams, heads that have been decked and blocks that have been decked.....well all your stock interference clearances can be thrown out the window. The only safe way to go about running avcs on built stuff is to clay the pistons.

Most folks on bigger setups seem to zero it out for safety....and most bigger setups are drag only cars and don't care about the gains below 4k anyway.

^ this is actually more what i was meaning...500-700rpm of spool is pretty significant depending on what type of driving/racing you are doing. no offense to anyone running 30R's, but i don't consider those BIG setups. i am more talking about 35R and bigger, and even the 35R's are borderline smaller than i was talking about...and honestly, if you are running 35R or bigger, you aren't really building the car for a tight and winding road course more than likely so...AVCS probably won't matter much to someone in that range anyways. like ron said, rpm's will be above the power gain threshold anyways.
