Maybe one day I will buy a crank driven vacuum for the crankcase but until then I bought K and N. GREAT FAST SERVICE to Canada straight from the company's website.I measured carefully and it's the only one that will work for this. I am trying to deal with blowby.

THANKS for the support, homes!

Wilson is back. Feels crazy crazy good to say that. Got the "baller on a budget" GT conversion with some sweet LED headlights in. Got my turbo drainage issues fixed. Last night I drove about 60 miles... and stomped on it a few times. This car sounds nasty (but in a good way). Got a taste of 6 pounds boost so far. If anyone has any SUCCESSFUL 2.5l tuning maps, hook a brother up would ya?

I totally agree that this is an awesome build, Noah!
So glad to hear that the smile is back after a bleak time many months ago...
I was thinking about your comments a while back about removing the rear wing (and seeing the mounting brackets still in place in a photo or 2), and remembered this site:
https://www.battleaero.com/collections/components
If you cruise through the site (even if it's really not geared towards us Porsche people), you will see that their wing kits have either a top and bottom horizontal rod or double diagonal rods between the wing supports to keep the system from racking side to side.
I think you could add something similar to your wing supports for added stiffness.
Should be easy enough for you to drill 2 small holes in each upright, grab two lengths of threaded rod, 8 washers, and 8 nuts to see if it works...
If it solves the problem, you can then make up something more attractive than a threaded rod...

Darn you guys give me a reason to keep ramblin' Tongue
Love you guys & thanks for the props! Bob, you bring up a good suggestion. I'm sticky with the stock spoiler unless i'm running say 300+ hp. So will re-visit the wing concept.

I did however experience like 250 hp unexpectedly yesterday! Cheesy




Got permission to bring Wilson in the shop to charge the A/C. But found the compressor clutch isn't engaging & the heater blows hot. When I press the AC button the voltmeter doesn't drop (like it used to when the clutch engaged), so need to troubleshoot. Was hoping to maybe take the car on a 9 hour road trip for mothers day this weekend, but can't if its blowing heat.

Also. HOLY SH***** I experienced 12 lbs of boost! Which I dunno might be like 15 lbs with a stock 944 turbo. So that means the Greddy controller responds to my input & the system works. The car just pulls, but then when I go 3/4-WOT I get possibly detonation and the knock sensor de-rates the engine or external waste-gate "screamer pipe" opening... I have no idea what is going on, because if feels like I hit a wall but it's below the 6750 fuel cut, and I can felt a jolt and forward acceleration slows momentarily. If I press the accelerator slowly,, then this happens less, it's when I press quickly that it occurs. The car is too rich and needs proper tuning so I backed off the boost. BUT WHAT A FEELING!

And I ditched the rally car/muscle car brake booster pump. It worked good, but now I'm plumbed in normal. Brakes feel the same.

Today was the first day of datalogging. It was also the first day of almost 13 lbs of boost. I was running 94 octane and a bottle of octane booster in the tank. No intercooler.
Based on driving this week, I was experience what I think was mis-fires with low (5 -7 lbs boost), on straight 92 octane gas and they were quite violent! So as a troubleshooting tool I upped the octane to see if it would go away & sure enough, today I could have cranked up the boost even more, as you can see the knock detection was zero. But, I suspect the tuning needs to be improved & that the octane booster is just a band-aid. One concern I have is at peak boost the ignition is retarded 22 degrees, but at 1 inch of Vac and even 4 lbs of boost the spark is retarded 32 degrees, should it not be max ignition retard at max boost and less retard during these other moments? My goal is to not have to use octane booster.

Its been a fantasy of mine to order McDonalds food through the drive thru in Wilson for like 5 years. I can now take that off the wish list. Last night almost midnight we were charging up and down the hills in the blackness of the foothills on an incredible road, these LED headlight are AMAZING! Then today after a drive, my throttle cable broke but fortunately my friends kid gave me the brake cable from his BMX bike & we were able to drive home.

I have to ask, anything special about ordering drive thru in this particular 944?

Awesome that you were able to make a bmx cable work as a throttle cable!!

MAZDARX7,
The fact the windows come down allowed me to order. The gutted doors used to be fixed shut, so no drive thru.

Last night: Drove the car finally.
It was a lot more crisp after minor tuning & large intercooler install with both fans engaged instead of just one! This car is actually FAST.
It's actually electric. Its so intense.

Since the first set of datalogs I have lowered fuel rate 6% leaner. But still suffer from absurd rich AFR issues when throttle opens up at around 3/4+. Next plan is to redo the accelerator enhancement and re-test.
Other changes since the first post:
- the day's temp was cooler
- I wired up both radiator fans to kick on at the same time rather than one.
- I built ducting or "air dam" around the rad.
- Changed antifreeze percent to 70 from 50.
- I added a front mounted intercooler.
- The tank was full of 94 octane and no octane booster
It was very interesting to experience that the car felt fast & I was surprised how quick it was considering the lower boost levels.
Perhaps this is a result of being a cooler air charge? Today I also noticed just a wee bit of knock (yellow) indicated below. This was very minor (I think because it wasn't detectable to the driver).

Its 3 am on Monday my day off and I woke up to work on Wilson. The turbo I had died due to oil starvation and I am caressing the replacement in place. I have read several forum threads online regarding the use of oil restrictors on the feed line and concluded it is vehicle specific (based on turbo bearing type, oil pressure). I have been running a restrictor seen here, but have since drilled through) and going to use a regulator to regulator flow & pressure instead. I think I am going to feed enough oil until it leaks through the turbo seal & then regulate one "click" smaller. I have a 1/4" hole drilled one the downpipe before the cat which will allow oil to drill out and this will be my indicator of "too much".

is it possible to tap into the oil galley between the oil pump and the over pressure release valve and leave the restrictor in place?

on the Mercedes w123 diesels, the drain is what would restrict the flow, even though it was a straight tube into the sump. with age it would coke up with baked oil after shut down.
