Are you tuning it in person or over the net? Is it using the factory BCS, a MBC or a EBC?

 

Tom - I drove 7hrs to OH to tune the car and we spent HOURS chasing our tail. Vince was off so I couldnt even find out if it was set wrong. What was weird is it let me flash a GMS1 cal overtop anyway lol

Dave - Right now we are back to net tuning. I just sent him my TF cable and the updated TF file yesterday. He loaded it and I sent an update today for the HP portion. It's FINALLY controlling the boost better, before was 10psi or 30+psi. Nothing in between

He is running the Tial EWG with the factory solenoid in line. He also has the intercooler, CP's, maf relocate and the Tial BOV as well.

Wicked - Do you have the wastegate lines run like their instructions sheet?? When I looked up the Tial Vacuum diagram it told a different tale. We are still running them per the ZZP details tho right now. If it still doesn't control the boost just right when we get to fine tuning it I may have him try switching it to what Tial recommends. I was going to PM them about it anyway and just ask their thoughts on it, or hopefully they chime in on it

 

Hmm, the vac lines may need to be rerouted. It sounds like it is either running WG spring pressure only (assuming a 10lb spring) or fully closed wg which should net ~30 psi.

 

Well the car is boosting correctly now, it's not spiking anymore. We successfully held 24psi today lol. Im just waiting for him to finish his clinicals and then send another log. He only tried the new file quickly and said it def seemed better. So we'll know more later

 

Must have been an issue with the stage 1 flash overlay.

 

I'm using the precision 46mm gate (going s256 soon), but yes I'm using the diagram they sent. DAL's are just shy of 200 and are very very touchy.

What kind of spike, like at around 6k all the way up?

 

It was def an issue with the sensor cal. He had it set for stock sensors and the car has the GMS1's. Now that that is fixed, it seems to be acting correctly.

We are running about 200 DAL as well and I have the MAL ramping up pretty slow right now. Everything is super touchy!!

 

200 DAL is more like 260-270 DAL because the WG spring is heavier on that turbo vs the stocker.

 

rip out the stock ecu and run this ish on motec lol

 

that and overnight parts from japan

 

You can put it on my tab at Harry's.

 

It's only 2-3psi higher then stock.

 

Ok so it is the crank main seal. Apparently under high boost the crankcase is becoming too pressurized and its spitting out oil past the seal. Idky other people haven't had this problem I guess it might be because the ring gap on the wiseco's is wider. Bout to make a custom catch can that vents to atmosphere

 

Setup is on there. Forged bottom end. Spec stage 3+ clutch. Zzp turbo kit. Nothing else is changed

 

55 more HP to the wheels on 7 less psi and a very conservative tune sounds pretty reasonable to me. The people surpassing 400whp are running ZZP charge tubes, larger ICs, and aftermarket catbacks and/or external wastegate dumps, as well as more boost.

Your forged pistons are likely costing you some power as well, especially if they are loose enough to cause crankcase pressure issues.

 

Forged Pistons are available with a high silicone content (%14 or so) that perform more like a hyperutetic piston. I have used these in big block chevy engines with very good results

 

But you put it on the dyno? That's definitely not taking it easy my friend.

Sucks about the oil leak and the low power, but if you still have 7psi in it, after some exhaust upgrades, 1psi should equal about 15-20 hp, so I'd say you can easily get your 100whp more out of it.

 

so who gapped the rings wrong? might wanna check the oil for fuel if its pressurizing it THAT much... the other option is to run something like Tony1's catchcan setup... its been proven well over 1000hp

T1 Crankcase Catch Can

 

Top Fuel

 

What are the end gaps on the rings? Sounds like you have excessive blow by pressurizing the crankcase and blowing the crank seal. It would also explain your lack of power as well.

 

nah, just an integra...


were running this can on my friends 2.0L B-series motor w/ a GT4088 that made 711whp on a 26" ET Street on Q16. it makes 500whp on 14lbs and 110 from the local gas station out of the pump.

 

The ring set that comes with the wisecos are already properly gapped. They should not have had to gap them more. They come with a pretty decent sized gap on them. Way better than stock. I measured them in the cylinder when I put them in mine and you could see the gap difference between the Wiseco set and the stock set. I havent had any issues at 24psi with the k04. I agree, though, that with more supporting mods you can be a little more aggressive and achieve higher numbers.

I see nothing about ring gaps on that, just piston sizes and what comes with it. nothing about gap sizes or which style of camfer was on the rings or anything... so what was the gap? "good" is not a measurement... and you would gap the rings a good bit different for 400hp than you would for the same engine making 700hp... sounds to me like the top two rings are either wayyyy too big or the gap was too small and they broke during a pull or possibly instead of breaking, cracked the ring land on the piston...

do a dry compression test and see what you get... i bet its WAY lower than it should be.

(if im coming across as a dick, its not intentional)

 

Or they didn't stagger the gaps.

 

That or they did not hone to match the rings.
