AU6 Flash Tune by G&D - every KW counts

Cheers Stav

On average an auto car will produce around 8-10rwkw less than a manual due to its extra rotating mass and torque convertors slippage not matching the manuals 1 to 1 drive to the rear wheels.Results would be similar with both styles of cyl head,even the stock AU head is a pretty good thing.

That makes me feel a lot better about my cars output then. Would be similar but deduct the auto (about 12kw different).

Thank you G&D.

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

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.

I like the look of the airbox. I've got a replacement intake pipe that fits the EF-size pipe mouth, not the smaller AU size - would your box mate to the pipe?

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.

G&D air boxes are the best made box, there insulated fit perfectly and have a very nice finish most important it works well.

Glenn nice work, good to see you guy's at G@D having a real interest in all cars...

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

I'm sure they could work something out. I would make sure of it lol. :

While they play with your car you can come round for a drink :

Sorry I cant remember your real name.
I was in the truck. Whoosha is my old man.

P.s Eyes off the rattle gun.... :jab: lol

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.

Mine was 123rwKw stock.

Exception rather then the rule. Stiddy's is the same. They are out there but they are the exception. Most of us have to work damn hard just to get to the level of stock from some of these engines. :( I wish I got one of them.

(I suspect Scminer1's EF is another of these engines).

you got a freak aswell, mine went 136.7rwkw with just a cat back exhaust..

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

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.

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.

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.

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

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.

Correct but it is unusual to see a small gain or even a loss by inlarging the intake on most engines.We saw a loss of only a few kw at the time of testing.I wan't to revisit this test though with our new tuning tools & I'll document it for all to see.We may come up with something that works with further testing.We even tested an enlarged throttle body on a 150 rwkw AU recently & saw not 1 KW gain.I think that the factory intake manifold design & inlet tract up to the air box is a fairly well designed thing.I will say that at G&D you will find that we don't beat around the bush,if something doesn't work we'll tell you rather than sell an inferior product that doesn't work just to gain profit or looks.Honesty goes a long way,it's been a great recipe for success for us over the last 27 years of buisiness.

I was there for that one, and i was hoping for some sort of gain.
Took the T/B straight back with the dyno sheet, the guy who made it gave me a refund, it was sold on the proviso it made some k/w gain and it didn't.
He isn't porting and polishing i6 T/B's any more.

G&D the throttle body on the AU is just as big as many american v8's.

What do you guys think is an attainable figure for rwkws from an inline six.I always believed that the reference was 1 horsepower per cubic inch.In theory we should be getting aroud 245 horsepower/182 rwkws .It seems that most are stuck at around 150rwkws.Something is holding most cars back...

Also I think that throttle body cannot improve on a situation when say the intake manifold may benefit from some extrude porting as well as the the head.What do you guys think?

Honesty like that will win you a lot of business... mine included. JMM have been exceptional to me... you guys appear to fall into the same exceptional catagory.

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 .
