So as some of you may have read, I was concerned about perhaps lifting my heads at some point over the past 2 years.
So today, I went out to the garage with the intent of pulling the cam covers and quickly saw that if I want to pull the front cam cover, I have to remove two IC pipes that I really don’t feel like removing. Sometimes I wish I had a few more couplers, haha.
Instead, I decided to check the spark plugs, do a compression test, start the engine and let it warm up, check the plugs again, and do another compression test.
I only did the front bank because cylinders #1 and #3 have always been the weakest… and frankly, the car is pressure tested and ready to rock -- If I don’t need to mess with it, I’m not going to.
Front plugs. These have maybe 250 miles on them. They’ve seen 29 psi a lot of times at the track and on the street. When I take my car out, it's pretty much all business. I either take friends for rides, romp on it constantly for my own enjoyment, or race other vehicles. They’re gapped @ .020” – haha. Original coils baby, yeah!!
The pictures came out blurry, but the plugs look perfect to me. No slag, no signs of detonation, no signs of burnt coolant.
Cold compression test:
Cyl#1: 130 psi // Cyl#3: 130 psi // Cyl#5: 135 psi (this is lower than it used to be by 7-10 psi)
Hot compression test:
Cyl#1: 150 psi // Cyl#3: 145 psi // Cyl#5: 147 psi
God I love my car. These numbers are identical to what they were over a year ago – which amazes me.
Here are some videos. They’re pretty boring, but for those of you that are just curious…
Notice the previous peak boost of 1.2 bar. This is what I was running on pump gas… I’d spin my street tires through 3rd gear (that’s only like 120-130 mph) at that boost level. Yay for FWD.
I have about 10 seconds worth of time invested in the idle / mid throttle tune on the car. The idle is the only thing that’s fubar’ed at all (lean), but it is usually rather stable once the engine is fully warmed up. Hell, I’ve driven the car with the engine ice cold and it drives fine – A little rich, but fine.
Yes, I was revving the engine after going WOT – my idle tune isn’t THAT fucked up.
Check the fuel pressure gauge as boost builds. It appears to drop 1.5 bar (~22 psi) as boost builds to 0.7 bar (~10 psi) in neutral. Oil pressure seemed to sit steady at 2.0 bar or higher the entire time.
Check out what happened to VR4-Case’s transfer case.
He did this on his first trip to SAR as well a his first trip to the track with 13T’s. 117 mph with lots of room left in the tune. He’s going to be getting my old brace which COMPLETELY prevented this from ever happening on my car along with my current turbo set up.
Here’s what my car does on race gas, with drag radials, with the suspension stiff as fuck from a 50 punch. I miss traction.

Here's a detailed description of what happened -
I put my BFG drag radials up front and stiffened up my suspension as much as I could (short of pre-loading the springs!)...
We went from a 50 punch both times. That's 5000 RPM's in 2nd gear for me. I regularly spin my 115,200 mile old engine to 8000 RPM, so I wasn't too worried about having to instantly shift.
Anyway, I didn't bother brake-boosting because I knew traction would already be at a premium. Instantly after going WOT, the tires were spinning. I'd tap my good friend, Mr. Rev-Limiter and shift to 3rd. I'd be welcomed into 3rd gear by what felt like an eternity of turbo lag (due to spinning the tires rather than actually accelerating in 2nd gear). As soon as boost built, the bike's pull would be STOPPED. As some of you noticed, it almost looked like I was starting to reel the bike in.
The first race was 50-160. The race posted here was 50-140 mph or so.
I was running 24-25 psi, 105 octane unleaded with the ignition timing pretty damn advanced.
With the current set-up (IN AWD MODE), the car traps 126 mph on pure 93 octane pump gas @ 22 psi. It trapped 129 mph @ 29 psi with the ignition timing watered down greatly. At the same boost level, I've been able to add 9* of timing since then and the car pulls much harder, even on lowly 105 octane. One clean pass will give me the 13x.xx mph traps that I want.
For those of you that are curious, the 600 has at LEAST a header and exhaust. The owner has no idea what mods are on the bike because it was modified by the previous owner. According to the current owner (not a newbie!), the bike may have a cam because of the way it idles.
Anyway, what REALLY matters is that we all had a lot of fun and no one got arrested!!!
Sorry for going all over the place, but it sounded like fun.

Oh, and did I happen to mention "damn you and Case for cutting me out of the E16G deal and not at least selling me his 13T setup"? Yeah. Just thought I'd say it again. LOL
