Think it's about time to spin some rollers (Aaron's dyno)

Here's my completely NA DOHC dyno at exactly sea level. You can see the correction factor is 1.00 due to the nice conditions that day. Mods are custom intake, some porting of the manifolds, balanced and blueprinted: http://www.pbase.com/series8217/image/8 ... /large.jpg

Here it is overlayed on Aaron's:

blue is hp, red is torque.

From 6k on, looks like I was right.

Wow, for a 1000 RPM stretch that I will never be in, save for a fraction of a second, Steven's car makes more power.

Then I shift.

I'm still amazed how you manage to completely miss the fundamentals behind how a wastegate works. It's baffling that people pay you to touch their car.

Hey check it out, I made an overlay of mine own!!!

Its Aarons AFR VS Lochness Monster...

It looks like the Lochness is a bit more leaner and meaner though...

Aaron · Post by **Aaron** » Tue Oct 28, 2008 1:39 pm

HAHAHAHAHAHA!!!! Lol, that's like perfect!

I like how the lockness goes down, into a safe AFR range, as brutal power comes on. But then it rises from the depths midway through, to impress people with that maximum power AFR. Then, whilst people's jaws are ont he floor, it dives again, gone until the end. Truly spectacular tuning.

YOU JUST POSTED HOW SWEET OF AN IDEA PUTTING A WASTEGATE ON BACKWARDS WOULD BE! HOLY SHIT YOUR HILARIOUS.

Aaron · Post by **Aaron** » Tue Oct 28, 2008 1:47 pm

And your technical argument why it wouldn't work?

Oh, you don't have one, because you don't even understand how they are supposed to work.

HAHAHAHAHAH

Dont make me post the aim log, dumbshit.

for the most control of a wastegate you want it as the priority.

3lbs of resistance is boost really.

pretty much all of the wastegates i know up, except mine, use rubber diaphrams. running a wastegate the wrong way would promote more resistance, which means more heat. that is if i'm jumping in on the conversation right.

As I said before, take the CF, divide it in half, then apply it, and that will be roughly what my car is realistically making. 376whp.

on 14 psi. Meh. It should be higher wiht your larger turbo then what matt has.

Matt had good tuning.

Billybo talks about some synapse wastegate all the time, he says its the bomb.

coo, i really like my synapse BOV

I'll be running a synapse WG. It looks like a really neat unit. I'm confident it'll perform quite well.

Systems Integration FAIL. Piggyback FAIL.

Bragging rights = zero.

Right back at you, tough guy. You don't have a technical argument for why it should work because you don't understand it.

And if you had a boost controlling ECM, you could set your boost to a MAP value and we wouldn't be having this argument.

Your percentages might work since it is cooler air the higher you drive to.

because cooler = less power.. righttttttttt

So what it's actually doing is unimportant compared to what you think it's doing?

What lab calibrates your butt dyno, again?

I think I predicted 300 whp. 377 or so according to aaron, on 14 psi so on 8.7-9 ish that would roughly equal 300 whp. I hate being right
