What Have You Done To Your Stagea Lately?

[Commsman]

I've got 5 in the post on Monday for Chris (Footo) in WA, but after that maybe a week?

How many cars does Footo have?

Well thanks for jet r31 getting me off my butt and giving me a hand, I've nearly finished hooking up my water/meth injection, then it's tune time again see what happens cheers brother . Also I fitted up my rear brake conversion and front adjustable camber and radius rod arms and chucked in a set of new tie rod ends and a afr gauge to go with the rest of the info in my cockpit

Ready for the cruise? Or you taking the daily?

[4bidn1]

Yeah will be ready for the cruise but won't have it re tuned yet, just running 17psi as before and no water/ meth turned on

Had my drivers side front wheel bearing replaced this morning; nice & quiet again.

Not doing it myself was the best $160 I've spent this week.

God I'm lazy.

F&R swaybars, coolent temp sensor, o2 sensor, N/A grill, pod. Got springs friday too!

You are lazy! Easy job is easy!

I was too busy welding today.

I'll do the next one.

Just got back from the retune.

Car now runs on the MAP sensor. MUCH MUCH MUCH more responsive, but no more power. Apparently 200kW on a Dyno Dynamics now, but no print out.

The weird thing is it's running Scotty's modded actuator and only running 9psi at the top - so it's 2psi more than last time with the stock actuator.

Got to get this boost sorted, and find out why it seems to be speed limiting still.

Much better package though, and much happier. Just want my farkin boosts!

[scotty nm35]

9psi? it sounds like you have a leak in the vac line, or yours is the only turbo not holding boost.

Did your turbo have a larger wastegate puck or something?

Perhaps the actuator doesn't have enough preload?

Check this. You need about 3mm of the width of the hole on the actuator for preload imo.

Bigkev ,no print out I would be asking "demanding a print out " it's an important reference to your car it's no good having all the bells and whistles and not having a guide to what it's doing and be a grumpy man if I was you

^ This. Just what the hell are they doing Ryan? You'd think for a shop with such a reputable name, they'd be a bit more helpful... or is it because you don't have an R35?

I think he's had someone else look at it..? or run it elsewhere. Dunno who has an AWD Dyno Dynamics unit off the top of my head!

Ryan, check out Theo's boost drop. He's stock turbo too, I suspect it's all about running out of compressor flow.

When I had my stock turbo it would hold at least 13psi to redline. No doubt it does run out of flow, but 9psi sounds too low.

How is boost control being done Ryan?

[andy65b]

9psi is the boost I used to get when my boost solenoid would stick open. Sounds like the wastgate is fully opening.

[bigkevracer]

Thanks guys. I'll try and tick everything off...

I've replaced every vac line now I think. I can't see how that would be it.

Stock turbo, stock wastegate puck. Andrew at AM wants to bore out the wastegate 1mm but nothing has been done yet.

Actuator is your modified one, exactly how you sent it to me. If it needs more preload do I just put a stronger spring on?

Check this. You need about 3mm of the width of the hole on the actuator for preload imo.

Which hole Craig?

Thanks guys. No printout, it was supposed to just be a fix session and the map ended up being redone. I could have asked for the printout. I didn't. I'd just sat in the passenger seat and seen the whole thing so didn't think to ask.

Mine was similar to that (although wtf is that at the end of the drop off?!). I wouldn't have thought it was running out of compressor flow that early? I thought others had more success on the stock turbo. Funny that Theo and I have both changed the vac hoses, and both get similar graphs.

Scotty's modded actuator with the HKS EVC.

9psi is the boost I used to get when my boost solenoid would stick open. Sounds like the wastgate is fully opening.

Weird thing is, it was 7psi without the modded actuator, 9psi with.

I want to see if I can find the boost problem, fix it, then take it to somewhere else to get the EVC setup properly and the tune checked.

For the record, the original tuner (who I won't name on here but some people know) once I explained all the issues offered to fix it, ended up retuning on MAP instead of AFM at my request, and spent near enough to two hours with me explaining things and talking about it. So far it seems like they have fixed it and improved it no end, but at the request of a few people I'll get it checked out just for peace of mind.

My actuator has almost 5mm of preload, the stroke of the thing is huge.

The hole Craig is talking about is the hole in the Wastegate arm, that the pivot pin goes through.

Boring out the Wastegate isn't going to make it hold boost better, if anything; it will allow you to bleed boost pressure more easily.

It would be worth doing if you were building boost pressure uncontrollably, but you have the exact opposite issue.

What's stock? From memory 3mm isn't it? And I didn't think Scotty modified that hole. Should I drill it out to 5mm?
