4AGE NA tuning

What can be done to tune the 4AGE for max performance without turbo charging?
Does anyone have or know of someone who has a 4AGE already tuned and could refer me to him or a web site ?
Also does anyone know the max potential of this engine, (anyone have dyno runs) ?

Check out my site, it should tell you much of what you want to know.
I've just finished a ~190hp odd 4AGE, and will be building a ~230hp one around the end of this year.

If it is producing 92KW, is this not 123hp. Likewise if it is producing this at the wheels what would the flywheel figure be?
My 20V is producing 92KW at the rear wheels at 6000 and I was wondering what this would translate too at the flywheel. Unfortunately the Rolling road did not perform the coastdown test so I could work it out.

92kw at the wheels equates to about 135kw at the motor.

or approx 180hp.....
our motor would gain about 15kw from using higher c/r pistons too.....(currently on 10.5:1 cr there is too much overlap with the 320 duration cams)

By those calculations you are stating that I am losing 50% of my power between the engine and the wheels. This is on a seven type car. I would have expected the maximun to be a 30% loss with the car producing 120Kw at the engine which equates to BHP160 at the flywheel.
I think the figures of 135KW and 180 BHP are a bit over the top.
Does anyone else know the approx losses between the wheels and the fly?

I'm not going to say anything definite, but from what I read its about 15-20% for FWD, a bit more for RWD (obviously) and who knows for 4WD because there are so many different drivelines!

But yeah, the best place to check this would probably be club4ag.com or Bill's site.

I work on 25% loss in a clubman with T50 gearbox.
That way you're not fooling yourself with over ambitious hp #'s at the flywheel.
To be honest, if I used 30%, I'd feel like a w*anker.
99.6kW @ wheels is 177hp (and feels like it - vs std 86kw)
111kw @ wheels is 197hp (and feels like it) - vs std 86kw)
I'm happy with the conversion, but what really matters is that the same dyno is used and the improvement from 99.6 to 111 is genuine. Maybe it's not EXACTLY 11.4kW, but it IS in the right direction. ie MORE POWER!

Puzzigully,
Before you make comments such as "To be honest, if I used 30%, I'd feel like a w*anker." Please find out all the facts.
As I stated in my original mail I said I expected the MAXIMUM loss to be 30%, that includes an adjustment for the fact that I live in Johannesburg at high altitude. Some say that the adjustment for this is actually greater than I have used. Therefore I could be underestimating the losses by a larger amount and so I am being conservative. You also have to take a number of other considerations into account, what tyre pressure do run, am I using a T-50, type of rolling road,state of exhaust, etc etc etc. NONE of these are were you aware of when you made you rude statement.
What I have just realised is that I was calculating my % losses the wrong way round and so I apologise to a few guys for that. I did not however accuse them of being w*ankers due to my error/bold assumption.
In order to maintain that this forum is kept informative and useful I suggest that you refrain form making bold sweeping statements about how you would feel if you used other peoples ideas.
Rant over!!!!!!

OK OK,
Settle down,
Please note: I said I would feel like that.
This statement was based on the fact that I (not you) would feel like I was kidding myself.
At no time did I intend to suggest that you (or anyone else)is or could possibly be labelled in that manner.
My opinions of other people are kept to myself and are not based on postings on web pages.
I am sorry you took offence, no offence was meant.
I was attempting to provide input to your posts based on my own experience
If you do not wish this input, let me know and I will not post again on any of your posts.

Yeah, even using the GroupA cams which are 308* and 9.1mm lift the 10.5CR (plus a bit through the TRD headgasket) the duration is a fair bit too much. Im currently pulling 113hp at the rear wheels, on a known conservative dyno, and 121 on a fairly liberal dyno. This is from 308* cams, solid shims, and a slightly higher CR along with quads, a haltech, GZE injectors, and a good tune.
I havnt had it dynoed with the Quaife box which i got at christmas (weird presents) nor with the 4.3 diff rather than the 3.9 diff. But it certainly feels like a good 165-175hp.
The new engine should be fixing at least one of those limitations, with some nice Wiseco 11.8:1CR pistons, and a higher redline, with longer duration cams.
