I already have a JBR OCC sitting in my room, so maybe I'll install that sooner rather than later. I can probably go for quite a while on a cracked ringland, but I'd rather build before it blows up.

I would just sell it and get a brz. They're at 640whp already.

Stock block.

Just buy this little upgrade before you install it. It will keep oil out of the intake.

Lol on my way to the dealership now.

But seriously did visconti tuning actually make it up that high on stock internals?

[Tokay444]

Yup

[Tokay444]

That's Toyota's influence.
They've been putting 1000hp cranks in 140hp cars for decades.

Actually I am just speculating cause Mazda recalled my motor but I haven't heard if anyone blowing through as much oil as I did. I wouldn't be surprised if my #4 had a hole in it.

I ditched my HF tester cause the guage stopped at 75. I bought a nice craftsman setup that had a customer review rating of 5 stars.

Anywhoo I tested a 08 with 110k+ miles running 21 lbs boost on a stage 1 map with K04 and 91 octane from passenger to driver side:

170, 170, 160, 170.

Installed a beaner last weekend.

Tested a 12 with less than 10k miles running a slightly modified Stage map on a K04 at around 17 lbs if boost from passenger to driver side:

168, 168, 164, 80 (87 Wet)

I told him to stock out. I am not sure how he should document this to get warranty coverage.

Well was the compression test on his car just to check over-all health of the engine or did you suspect there was a problem? Just have him tell them it feels like it is down on power and request a compression test. Lol.

Well with all of the fail I have noticed lately, I find any excuse to whip out the compression tester.

That's probably for the better. Lol. But, oil consumption and loss of power are probably the main things someone would notice due to low compression in one cylinder.

if anyone still looking for results
pass to driver 170,165-170,175,170

mods corksport intake and tip, hks ssq, and an ap stge 1 93 tune

[kimura]

just hit 80K miles so I thought I'd do a comp test.

results were ~178 ~177 ~178 ~179

this is exactly 7 cranks for each cylinder, with all the plugs out, foot on the gas pedal. I've put about 11K miles on the 3071 over the course of a year.

[himurax13]

After 1500 miles on the replacement engine and stock everything, 185, 180, 180, 180.

Sent via stocked out for a while ...

[BigBoostMS3]

I did mine last week. ~85k on it. ~15k of that has been modded.

[breakfasteatre]

last night, 42k kms on my poo

175-175-170-150

a build is already in the works, alot of racing on the weekend..

[mrQQ]

you guys make me jealous

[soul.survivor]

Last weekend, 89k.

Carbon buildup on tops of pistons??

[himurax13]

For @SoCal MS3; at approximately 63K on a bone stock 2008 Speed:
185, 180, 185, 185

I think she is ready for Big Turbo.

[Tyhackman15]

2008 53k tuned for ~2k miles

180-185 across the board

I'll be trying mine again soon. Anyone have any tricks to keep that damn adapter piece on the tester and not get it stuck every time in every cylinder? I spent hours doing my test due to this and that shit had me ready to burn my car to the ground.

Are you talking about the part that threads onto the sparkplug hole? The threads on the adapter might be shot. You could try a little oil or some anti-seize if you are frisky. It should spin out easily.

Tape it on after threading it fully (electrical works), thankfully I thought of that right before testing the 1st cylinder

[Tokay444]

Just crank it tighter onto the the tester, tighter than into the plug well.

[himurax13]

OK, I must have read that post wrong. Is the adapter coming off the tester itself or is the part that screws into the sparkplug hole getting stuck?

The Craftsman Tester I posted earlier is the tits because the adapter simply screws into the sparkplug holes and then attached to the guage with a quick disconnect. The test itself takes less than the time it takes to smoke one cigarrette.

Now if you have POS Harbor feight one, I used teflon tape and 2 crescent wrenches to make sure the quick disconnect piece is attached properly to the adapter piece that goes into the sparkplug hole.

[fredricktsang]

anyone know where to get just the hose/adapter/fitting to the gauge?

[Tokay444]

Try emailing the manufacturer.

What the fuck!!!

[btstarcher]

Needs to be done at close to operating temp.

Did you push the throttle to the floor, how many times did you crank, was the tester good?

[skiptowncat]

I don't know wether the throttle was pressed. I'm going bnr soon so ill get the valves cleaned at the same time. I just hope it lasts till then.

Performing a proper compression test(and leakdown if the test results are bad) is far more important than getting a Beaner or cleaning your valves. If your engine needs a rebuild, then there is no point in doing those things.

The Beaner will put more stress a dying motor and will force a rebuild much sooner.

[Tokay444]

Replace lost compression with more boost.

Tried that, didn't last too long, lol.

Going forged as well this year.

Try a different gauge, I doubt that's anywhere close to actual.

edit:If the engine runs!

[skiptowncat]

I will certainly be getting it retested ASAP.

Throttle was to the floor. Engine did 10 compression strokes .compression tester was brand new as well and i later did mine and got 170psi right across bar cylinder 3 which was 155psi.also done on a mildly warm engine.

skips car on roadtest actually feels to have uneven power across the cylinders ,having solid mounts help you feel it more.told him to try a seafoam through it along with a fuel treatment ,then after 1k get it retested.this should tell us if its a carbon build it sticking the rings or the valves being poorly seated due to the usual disi intake

[skiptowncat]

I'll get a leakdown test as well

Did another test today, same location about 78deg outside and while the car was still hot. Just over 65k miles on the car now and back to stock.. for now. Cranked for about 5 seconds on each:
