AU6 Flash Tune by G&D - every KW counts - Page 2

xr8ute · 11-02-2006, 12:21 AM

Grant, whats with the dip in torque/power between (roughly) 55 and 70km/h. Is that something in the tune or just related to loading up the dyno or something?

Another great result out of Cranbourne

Also, unless you have owned the car from new you cant be sure its stock. I had a discussion with a person on another forum about a very high figure from a 'stock' engine. This person swore the engine was untouched and I told him the dyno numbers were to good to be true. The engine was pulled apart shortly later for an upgrade only to find an extra set of shims in the rocker arms.

Some engines are strong though (and some dynos are full of it). Id class 119kw as a healthy engine for sure, any more and Id start wondering what else was going on.

Albeit mine is an Auto VCT but with just exhaust , mine managed 127rwkw.

VCT's run about 115 stock and with a full JMM exhaust thats not suprising at all. Mine was similar.

Thank you G&D.

One other thing guys 119 rwkws out of manual equipped xr6's is not uncommon.

The insulated plastic boxes repell the heat better and maintain a cooler intake charge.

I disagree. HP's normally dont run any more then 110rwkw. 119 is not out of the question by a long shot but its n excepetion, not the rule.

Mine was dynoed with everything factory and I got 127. I think different dyno's tell a different story. You should have to do the before and after to guage how much of a % increase in power. This one tested did 25% increase at the wheels. I think that would give a more accurate figure to see the before and after on the same dyno. Would give an accurate account then.

Thats exactly right. In the end though we can clearly see a 25% increase, regardless of the numbers. All in all an excellent result

My VCT is near the same at 125rwk with just exhaust so in total stock form most should be 110-115rwk

Thats correct.
Its all "guesstimation" but its commonly accepted for the AU's that the Stock VCT will run 110-115rwkw and the stock HP's 105-110rwkw. Of course there is always variances to this but thats the generally accepted figures I have come to see more times then not.

**Stav** · 11-02-2006, 04:40 PM

Regardless of the nit picking a 25 % increase in power is not too bad.

I'm on the other side of Melbourne, so getting to Cranbourne is tough. If you could do a tune on a Saturday I would definitely be interested.

I'm sure we can help you,i don't see why the EF pipe wouldn't fit,we just havent tried it.You know its funny,we've found during testing on the dyno that a big is not always better with the I6,quite suprising.

It's when the dual stage intake manifold changover point took place,it seems to become more exagerated with the increase in power.

Cool, thanks for explaining that.

Mark351 · 11-02-2006, 09:11 PM

I might be good to experiment with the larger intake pipe vs stock intake pipe when tuning then.

This engine is stock & the car was delivered new to the owner,he has always run it on a healthy diet of 98 octane fuel otherwise it was dead stock.We've taken care of it's servicing from 10000km onwards from memory.I agree with what you are saying though,in some instances i've seen what you have unless people have owned the vehicle from new.At the end of the day a dyno is a good tool for tuning & measuring the pecentage of difference whilst & after performing mods.

Cheers Glenn

A little while back we did some testing on MATT@G&D's wifes AU I6 on the dyno.We manufactured 4 diferrent sized bellmouth intakes & tested stock AU right up to a 65mm opening from memory.On test we saw a loss on torque & power with each & every inlet tried above the stock size,even when the tune was optimised to suit.This had us gobsmacked.This argument was brought up the other day when we were tuning this AU & we plan to revisit this testing again now that we are tuning to a higher level of power.We love Dyno R&D & if something can be tried we'll try it,if there is power to be had we'll have it

This is very interesting info to see tested and isnt at hard to believe as it seems. I take it as a game of veliocity vs volume and, in this case, it looks like velocity is the winner. Can I ask what sort of differences were seen? Are we talking 1rwkw or 5rwkw? Just curious as this is something I remember discussing with you guys ages ago about the "restrictive" std AU I6 intake piping and the fact that it wasnt restrictive at all (well, at least to 150rwkw where you tested it).

More info please.. I'm very interested in looking at this in more detail.

I love this.. another AU I6 tuning house that is doing the hard yards for us

This topic so far has been a excellent read to show some people that you dont need to go and spent $2500+ to extract great numbers out of the 4.0 engine.

Now after doing what most do go and install a chip then swear and curse afterwards due to B/S numbers+costs and getting the runaround and power increase im tending to go towards the flaser unit after the feedback and results these little units are producing.

Full exhaust, airbox, flasher and tuning wouldnt be far off $2500. Thing is though that $2500 for a 25% power increase is a hell of a bargain in anyones language. I dont think you could get a 25% increase in power from many other engines for $2500.

I don't think the intake pipes do to much execpt for looks.
I have a 3" on mine with a T/ford snorkel & a paper a/f.
The only rwkw gain over the stock intake with a K&N filter & T/ford snorkel was 2.2 rwkw on the same dyno.
But the a/flow was a lot worse which I suspect was the stock paper filter one over the K&N one more than anything else.

12-02-2006, 03:46 PM

when i fitted the jmm pod and pipe to our au ,it picked up a lot more top end and lost a lot of low down torque below 2400rpm ,this was after i fitted a cam though .

stiddy · 12-02-2006, 04:30 PM

thats one thing im picking up while im down for the AU BBQ day..

the JMM ultra flow intake pipe... gotta be better than my home made effort lol..

I might be wrong. But I thought the idea of freeing up the induction side is to get more air through the heads easier/faster. And so, if you don't open up the exhaust side with an effective set of extractors and a low resistance exhaust system to clear the extra gas faster, then I doubt you'd see much benefit from a better induction pipe.

just a thought
