Dyno this year?

Once the fuel delivery mods are complete, I will be able to run over 21 psi boost without running out of volume, so, yes, I will be (AWD) dyno'ing to see what I'm making at 24psi (should be right around 500wheel), maybe higher if the tuning feels right.

finishing up the sender unit lines & fittings upgrade to 3/8" from stock 5/16".

Not going to finalize install until after Carlisle, to avoid jinxing myself...

They haven't had a Dyno available the past two years anyway :(

I heard they were having one this year. I saw there was none last year, but the year before wasnt there one that required having to take the wheels off to dyno? Something weird I thought....

If there is one, I'll consider yanking the DS. The one the year before was Audi/VW only - it was one of those pita bolt to the hub jobs. He (the tuner) cooked a motor on it.

Forgot to add the Aerocatch Hood latches

modified stock brackets for the pins

Waiting for the Ishihara-Johnson crank scraper/windage tray kit.

Cieka 6pot rear brakes with integral eBrake setup ordered after much back & forth to determine if it will clear with the limited clearance.

X1/9 hopefully back on the road soon, so I can then take the wagon apart to finish the fuel delivery upgrades.

A few updates.

Fuel system upgrades were finished a couple of months ago.

AN-08 Fuel inlet to rail

4D120728-8058-4792-8B4F-C890D8C78E62_zps

Left sender access

V70XR_0049.jpg

 

V70XR_0056.jpg

All lines uprated to 12mm. All fittings on senders now 3/8", with 3/8" tubing replacing stock 5/16"

SS LGSpeed Header to replace the mild steel version that rotted out at the collector

Revised SS DP to go with

SS intermediate section with Magnaflow 14419 resonator

1C548C55-84F4-4AED-B0A7-D91C24A50092_zps

I will redo the tail section in mandrel bend SS when I replace the Magnaflow 14834's with the longer body (quieter) Magnaflows. No I have the TIG, I can do it all myself.

Now running onboard COP instead of TTCOP - I added the connector for TTCOP inside the ECU, so I can switch if needed.

A friend gave me this light table, which made soldering the resistors much easier

A3766EEA-7476-4FBD-BA64-DB874D24A515_zps

Once I have the confirmed all my coil pack issues are behind me, I will get back to the dyno

CEIKA rear BBK finally installed. 330mm, 6 piston calipers.

Minor updates to keep the thread from being archived.

GM coils have been on & off. I haven't been able to resolve the breakup over 21psi boost that occurs with them. I ran them to Carlisle, and again to Ithaca in the hopes that I could do on the road adjustments to resolve the problem, but it doesn't seem to be dwell time at the root of it, at least not specifically. 

Having LS9 coil pack tested by Piet (many thanks) to determine ideal dwell table for those. They have a base dwell time much closer to the Bosch setup. Trent used them on his previous setup.

The driving force behind the coil switch, is that fro whatever reason, I have random coil failure with the Bosch coil packs. It's never the same cylinder, and without any COP diagnostics, I can't tell which cylinder has failed without switching out all five, then reinstalling the removed ones one at a time, to determine which cyl is failing under high load. That gets old real fast.

With revisions to the TunerPro tuning capabilities of M4.4 (thanks to Piet,Venderbroeck, et al), we are now able to properly map load up to 24.48ms instead of the factory 12.24, and record RPM up to 11k, instead of the built in 7650 cut off. This means that I'm no longer running at the max load values from about 25% throttle on up. As a result, I can dial in more timing and more accurate fueling, with the revised AFR based VE mapping.

Ostrich2 inside case

V70-XR-0096.jpg

V70-XR-0082.jpg

max load set to 16.99, that is slightly over the peak load I recorded @ 26psi

TimingVEchangesAfterJun03log_zpssq991uvr

As a result of all this, I am now achieving high torque values. The downside is that I have reached the rated limit of the AP Racing clutch (440ft/lb) :( 

60-100 just over 4sec, with 2-3 shift. some timing adjustments made after this. Avoided clutch slip by winding it out in 2nd, instead of doing a straight 3rd pull.

60_100Jun18_zpssufigvnq.png

I will be reinstalling the Spec Stage III+ full face setup, with a Spec flywheel.

V70-XR-0215.jpg

I also wore out my used AWD components - I never bought new parts until now - so I bought a new left Volvo (manual) axle, new Angle Gear, PdV higher rated spline coupler, and a Colorado DS 2000MY version driveshaft.

V70AWD_00033.jpg

The new 31256008 spline coupler I had installed with the AP clutch was shagged, and the AG splines along with it. It exhibited itself as a nasty vibration under load.

I also installed the Ishihara- Johnson Crank Scraper & Windage screen kit I bought last fall. New Volvo TTY crank carrier bolts used.

test fit for clearance

final fit with shaved teflon

IMG_6079_zpsvkksgya1.jpg

haven't driven it enough since install to see if it makes any difference to oil consumption due to reduced oil clouding around the crank.

Also modified the heater hoses at the firewall (thanks Matt for the idea). I reduced the length of the elbow offset, reusing the stock barb & firewall insert

revised in place

F2B20E16-74E5-445B-AE2F-17F94E5AB432_zps

this was necessary to get clearance for the 4" lower inlet piping - I had previously used a 3.5" section with a step to the 4" MAF housing section, due to the interference with the heater hoses. Now the 4" just clears.

0713C5E7-571D-4D4E-A649-2BCEF9A91F27_zps

I also moved the dump valve section of piping back to the upper section, as this makes access to the shifter cables & wiring etc over the trans easier to service

94F6EDDB-6BC9-4C21-B6A6-35E07CDB30DE_zps

Thanks to VulvaS40, at some point last year I determined the air filter I was using was insufficient in terms of flow capacity for the PTE6262 at the projected boost levels. So, I had to revise that. Now using RU5045. See page 150 of my main thread for more detail.

V70-XR-0011.jpg

Previous filters...

E26150A1-F17E-4ECF-B37E-C8B9C905C067_zps 

The problem is that my airbox doesn't work anymore, and there is no room as it is for a larger housing. So, I will be relocating the battery to the cargo area, and building a new box using the current battery location space.

EDIT: forgot  - I also figured out a way to use the CEIKA rear hydraulic eBrake setup.

no more shoes! I was able to discard the drum & all the junk related to the shoes. Much cleaner install. I'm happy.

Installed the new AWD parts & the Spec clutch over the past few weeks. Installed on 7/30/2015 at 192,990k miles

V70AWD_00063.jpg

Also switched to the P1 style shifter & cables to see if the shift is more precise under hard use. Have to finish bedding the new clutch before I get aggressive with it.

750D1CB2-3683-457B-91F7-8B2AD59EACCC_zps

Moved the battery to the cargo area. Wiring was a bit of a PITA, but it's all good now. I bought the hydraulic crimp tool to work with the 0/1 AWG crimp connectors.

With that out of the way, I looked at the space in terms of fitting the larger filter diagonally in a new box. It's so larger that it would fill the entire space, and require an offset to the MAF housing that just seemed plain awkward.

So, I made a diverter tray to fit under the filter in it's current location, with a air funnel feed from the left side bumper grille.  I used the plastic tray insert from the cargo area space saver tub to make it & the cover.

73FC7564-9D70-4904-8914-5564480259A4_zps

Then I made a cover that encompasses the upper air feed in the stock location.

The build has come to it's end. All five Wisecos are cracked, one lost the rear skirt.

V70-XR-0012.jpg

Car is being parted out.

Intake, Turbo, Cams, IC, Injectors, NRG mount & OMP strut brace are under consideration now, everything else is available if you're interested LMK via email so I can track whoever asks for what on a first come basis. husseinholland AT gmail.com
