Just got back from the Liberty club dyno day at Edge Motorworks, i'm buggered after strapping 23 awd cars down to the dyno but what a great day.

Anyway, my winning result was 341.1kw at around 23psi, just shy of my 350kw goal. Cihan (my tuner) decided not to push it further as the compressor was out of flow again and he doesn't want to see me brake it for no reason. Very happy with the result though, its unbelievable to drive and it's a stupidly responsive turbo for the power output. Also good to hear that the Edge dyno is comparable in output to many of the other local tuning shops.

Shame I didn't get the torque graph, you can plainly see the compressor flow dropping off as efficiency goes out the window.

Awesome effort once again Scotty; you must be stoked with the result.

Never ceases to amaze me just what you've been able to acheive with this car; sure has come a long way since that 180ish kw dyno run!

Well done.

Thanks Dale.

Is that power rwkw or awkw? Either way I'd be happy as a pig in you know what. Good job.

Still rear drive, I need to find time to drop the engine and fit the 3.5:1 front diff but there is always another Stagea in the way. lol.

It appears you have very little below 110kmh and all the grunt is top end. Is that how it is to drive and you need to row the gears a bit? Not a criticism just curious what it's like vs the dyno sheet.

[scotty nm35]

Generally in 4th gear you wouldn't have anything below that sort of speed, its not like you take off in 4th from the lights. The goal is to have at least 4000 revs of usable power then select the correct gear to use it.

Obviously this is much laggier than the stock setup but above 4000 revs it is very responsive, boost hits instantly. its only below that where is comes on slower but it is still acceptable in my eyes, remember most of the highflow turbos going in are around the same wheel size, mine just has a larger rear housing for flow.

[PN-Mad]

What did you Rev it out to? I would have thought top of 4th would be over 200. Guess I'll see on the dyno on the weekend. Didn't look at the speedo last time.

Ok thanks for the explanation. When do you get boost in 1st gear then? I can't imagine what it's like to drive our cars with a laggy turbo as they seems such slugs until boost kicks in. I imagine yours would be a whole new ball game with a manual box in it. Are you still considering this?

The dyno has a speed restriction of 200kph, I have no idea what revs its at when it hits that. Seeing we run the same diffs can you let me know? Are our gearboxes the same ratio?

Boost in first is absolutely useless, especially in rear drive. (It will light up second in the dry) Usually around 5k I would say at a guess. Remember though, I have a 4k stall converter once boost ramps so once the initial second of nothing has passed it is always on boost, whatever gear i'm in.

It was interesting going up a hill on the freeway in the wet the other day, just leaning on the throttle, and as boost ramps the car stepped out at 100kph in 4th. I need the front diff in soon, before winter hits.

So yes we should be the same ratio's depending on your rolling diameter.......4th gear should just about be smack on 220-230km/h for you!

You mean like a few weeks ago??

At least you guys can drive...try public transport in this shitty weather...

[iamhe77]

At least you have public transport

I have to walk to work 65kms each way... in the snow... uphill...

Both self inflicted so no sympathy here. lol.

Both self inflicted aye???? Please explain!

Jethro is walking due to his lead foot syndrome and Cam decided to live in woop woop. Self inflicted like I said.

I'll check it out on the weekend and let you know.

[WAGON_BOY]

i know 3rd goes to 160-165km/h on mine cos i was just shifting into 4th over the 1/4 mile

[PN-Mad]

But cool people run 3.538:1 final drives....

jks Theo!

Thats what we're wondering about.

[scotty nm35]

Thanks Alex, it will be interesting to see how much of the graph is missing. Perhaps there IS a little more in it...

I don't think more lag would be a good idea, although I can still hit full boost in 5th on the freeway cruising thanks to the stally. I'm probably going down the built 3.5 path next, just to give you a run for your money Alex. When are you winding up the wick?
