Re: Evo X upgrades
 

I do but I didn't want to post them. It's bad. The tubular, MX1s and ported everything had a negative impact on spool. I only had a 2psi drop at a stock redline but at 9k it was 5. I might have leaks. I dunno.

Re: Evo X upgrades
 

Nice numbers!

Re: Evo X upgrades
 

Has anyone tried a simple MBC on an X? Wonder if it'd help at all with the loss of psi. Or is the turbo just running out of breath up there?

Either way, still a killer setup with great numbers, congrats again!

Re: Evo X upgrades
 

Don't be ashamed! 25psi @4000rpm is dandy for that turbo! Having ported *everything* like you have will make it hard for the turbo to hold boost up top--don't worry about it, but you definitely start to look close at 7500rpm and say, 'man if I just had an extra 2psi I'd have +20whp (or whatever)....this is why I did the hybrid mbc/bcs thing, we'll see if it pays off.

Again, sweet results from a great setup! With any luck I'll be in that ballpark down the road.

Re: Evo X upgrades
 

Great work! Finally! I bet it feels good to finally have a proper tune! Congrats.

Don't worry about the drop in boost, mine tanks the same way...drops from 37-29psi for me, so your drop isn't so bad, lol.

I'd blame the spool on the tubular, but honestly I bet you made an extra 15+whp from it. Worth it if you ask me :)

Now time to stop spending money, paying off debt and enjoy the car...welcome to my world if you weren't here already ;)

Re: Evo X upgrades
 

Not quite yet due to the oil burning. There also seems to be an exhaust leak at the turbo to downpipe connection, so yet another reason to have the turbo pulled. At least I can stop spending money on fueling.

Re: Evo X upgrades
 

For now :D

Re: Evo X upgrades
 

They drop boost much worse with an MBC. With an MBC in there it would probably be a straight taper from 30psi down to 20psi. He could maybe try to use an MBC in there with the BCS to try to have more duty cycle to play with liek Schiedes did, but there might not be much left in that turbo in the upper RPMs anyways.

Re: Evo X upgrades
 

I think boost is dropping so much just because the head flows so well and the motor is just gobbling it all up. The X's head flows great in stock form, when you port it with oversized valves I am sure in the upper RPMS it can ingest a shit load.

Re: Evo X upgrades
 

There have been a handful of all-out BBX builds while I was busy sorting the car. One guy is running 35psi and making more torque but I think the hp number is as high as its going to go.

The 044 on a BAP should be able to handle a Black, which is the only upgrade that I'd consider.

Re: Evo X upgrades
 

Link to a guy running 35psi on a BBX? Did i really miss that one, or maybe I just forgot.

Re: Evo X upgrades
 

It was in a guy's sig on EvoM and not a dyno or build thread. He did 500/500 on Tobz's dyno. I'll link it if I run across it again.

Re: Evo X upgrades
 

Was just now able to see the graphs. Nice numbers dude!!

Re: Evo X upgrades
 

I'm working on re-doing my catch can setup. I'm replacing the vacuum line that I was using with fuel hose since the vacuum line was weeping oil.

I exchanged emails with Chad@CBRD and he concurs with Ron that it's most likely crankcase pressure. With the dipstick blowing and other symptoms, I guess that makes sense. I'll drop Grimmspeed another line about their AOS.

I'm not keen about drilling holes in my valve cover and going to a more elaborate catch can arrangement but if that's what it takes...

Re: Evo X upgrades
 

Have you tried just removing the catch-can setup all together for a test? My guess is going back to stock routing would cure the problem (PCV to IM, VC to intake). You can leave your check-valves in place, as long as the ones you got can flow a decent amount of air they shouldn't be the restriction.

The only other thing I can think of is your piston rings not sealing well. You just did drop-ins, right? Have you done a compression or leak-down test yet?

Re: Evo X upgrades
 

He has just straight up drop-ins, so it's very likely the cause.

Re: Evo X upgrades
 

Is this something that would've been solved with a hone or why you guys recommend a hone?

Just curious because technically I "just did drop ins" but it was on a fresh motor.

Re: Evo X upgrades
 

I did on the front side but my Primo intake doesn't have the fitting. I've thought about dropping them a line to add one.

Looks that way. There's no way I could afford to fix it, either, if that's the case.

Re: Evo X upgrades
 

Sounds like the next step. I'll wait a week for my fuel hose to come in (ordered it from Jegs) and see if Grimmspeed gets back to me at all. I have an email off to Jesse to see if I can bring the intake in for a fitting.

End of the month I'll probably leave it with Ron for a few hours and have him run the usual tests...leakdown, compression, and pull the plugs and take a peek in the cylinders.

Chad@CBRD is an odd guy. One minute he comes across as stern and the next he's joking. I haven't quite figured him out.

Re: Evo X upgrades
 

You dropped in new pistons/rings without running a hone or anything? I'd definately say there's a chance that could be the root cause there. The rings may have never bedded in well and hense the increased blow-by.

Pop the head off, oil pan off, remove pistons and rods and run a quick hone up and down. Re-ring and see if that helps. Alothough I don't know Evo X's so I have no clue how difficult removing the head and oil pan is compared to a dsm.

Re: Evo X upgrades
 

Not easy at all.

Re: Evo X upgrades
 

Shane didn't want to hone it in the car, said we'd have to pull the motor and that's what led us to where we're at. I'm not a mechanic and I can't afford to have that kind of work re-done. I assume it'd be over $3k to pull the motor to do that right.

Even at Amsoil's $11/qt that will buy a lot of oil.

Re: Evo X upgrades
 

Id say before jumping to conclusions, Do the necessary troubleshooting steps then worry about whats next.
If the car runs good, just let r buck, enjoy this thing!

Re: Evo X upgrades
 

$4.40/qt Mobil 1 FTW :)

Re: Evo X upgrades
 

I'm not worried, I'm just saying the rings are staying in the motor unless it stops running right.

Re: Evo X upgrades
 

Just curious, what makes it so difficult in comparison to say a DSM or Evo 8?

And while I agree that yes the ideal way would be to have the motor out, does that mean it has to be done that way? I did the one cylinder on my talon with the motor in the car. I had a bunch of rags/blankets under that cylinder, around the crank, to catch as many particles as possible. Then wiped down the cylinder walls as best I could with rags and tranny fluid and wd40. Never had an issue. Shane when you did the pistons in your 2G, those were just drop in correct? Did you remove the motor for that?

Just a thought, to each their own :)

Re: Evo X upgrades
 

I am sure Shane could answer this best. Basically every time we talk about the 8/9 vs the X he says how much more work the X is to do. I haven't done it personally so I couldn't tell you.

Re: Evo X upgrades
 

What he had said to me is that if it were his car he'd turn the motor upside down on an engine stand and hone it but he wouldn't do that on a customer's car.

Re: Evo X upgrades
 

Whenever I hone a block, I pull it out and apart to make sure nothing gets in there. It makes a huge mess when you ball hone a block. I am not comfortable doing that in car on a customer car, it doesn't take much metal to screw up things.

Re: Evo X upgrades
 

...and a spun bearing down the road

Re: Evo X upgrades
 

FTFY.

Re: Evo X upgrades
 

I haven't done either, was simply relaying what others who have performed the work have said. You have now done that, so I defer to your expertise ;)

Re: Evo X upgrades
 

Planning to bring the intake to Primo tonight. I'm going to have them weld an AN fitting on it for a return from my catch can.

Re: Evo X upgrades
 

I was doing a lot of reading on crankcase ventilation today.

I'm probably wasting my time trying to make the stock setup work--it is only a single fitting that couldn't be more than 3/8ths. It sounds like most setups are running two to four large AN connections (AN10+). Four is obviously overkill but I won't get much ventilation with the stock setup.

I did learn a fair bit. The can on the front of the motor (PCV to intake manifold) collects the most oil but is apparently not the important can for ventilation...the back one is.

For now I'm going to get a fitting on my intake for that connection and see if it does anything. My suspicion is that I'm going to have to pull the valve cover and have some large fittings welded in, along with a different catch can.

Re: Evo X upgrades
 

Went to drive the Evo to Sensers tonight. The car dies every time that I let the clutch out. Doesn't move at all. I fear that something expensive happened to the drivetrain on my venture into the snow on Saturday. Guess I'll try warming it all the way up tomorrow night and try again. FML

The beater works and the Blue Moon is cold. :)

Re: Evo X upgrades
 

That doesn't sound good at all. Hopefully its nothing serious.

Re: Evo X upgrades
 

Does it idle ok?

Re: Evo X upgrades
 

It starts and runs fine. I revved it a few times and it felt like the car was cold but responding normally. I tried it three times in reverse and once forward. It didn't move at all, it just conked out.

Nothing seemed unusual when I parked it. I'll try it again on Thursday night...bring a flashlight out to the garage and see if I can see anything (like a puddle of fluid!).

Re: Evo X upgrades
 

Was your parking brake on?

Also I have had parking brakes ice up and stick to rotors before. Perhaps that is what happened and you need to jar the ice loose.

Re: Evo X upgrades
 

^ +1 on that ive had it happen a few times to me. ive also made the facepalm mistake of leaving the hand brake up.
