As I said depends on the stand you buy, I have one here that needs 100mm long bolts there is no standard Brian.

mmm toast

You mean they're not?? ;) (people here used to get offended when I said they were "just a car")

From memory when you alter fuel with a PiggyBack it changes timing as well due to the way they "fool" the ECU.

I tend to be very conservative when I tune and always have a good safety margin in my engines to allow for a dud load of fuel if I'm 1000Km from home. I also monitor EVERYTHING and on the new engine with be using active knock sensing/control for the first time. Never been a big fan of...

Measure axial and lateral float in the bearings/shaft, check the general condition of the fins on both the compressor and turbine wheels is about it. If either wheel can contact the housings steer clear of it.

Just trying to be constructive, it's all about buyer confidence. (year 9 formal education so if I can make an effort anyone can)

There are a lot of variables but yep that's near enough, anything you can do to lower the intake charge temp helps keep it out of det but there are hard limits involved, you can pull timing but you get to a point where you would be better off dropping boost and adding timing as it makes the car...

You can have perfect AFR but if there is too much timing/boost for the octane fuel being used it WILL detonate Alec.

Google it ;) I'd be having a real good look at the ringlands if you're using Cast pistons.

More than likely the effects from "incipient detonation", you don't hear it but it's there rattling away in the background.

Damn expensive way to learn :( Willing to bet it rattled itself to death, what fuel were you using?

ahhh ok (you're getting to the point mod wise where you need to know these things)

What timing do you run at that RPM/Boost?

<glances around, this cannot end well> :runaway:

Depends on the engine stand legs, you want at least 1d thread engagement in the block, 1.5d is better, "d" being thread diameter. eg: If the leg is 60mm you would buy bolts with 75mm under the head.

Don't make me send you to your room Lad ;)

Hey that&#8217;s why those vacuums are so hard to sell, if you can sell one of those you know you&#8217;re good. ;)

The line starts behind me ;)

LMAO it's a Supra we all have one of those ;)
