Educated Guess At The Final Tune Results

[Ben C34]

So Pete you have replaced

Engine

Exhaust

Turbo

Ecu

Injectors

Fuel pump

Clutch

And soon to be manifold.

What was the reason for poor response? Not much left.... Intercooler?

[AngryRB]

XKLABA- yeah fair enough, just seems a shame, a 3.2L off boost you'd think would have enough to satisfy off boost even as the VL non turbo was good, I just envisioned the 3.2L would be good then after say 3500rpm it would be an animal to the redline.... hence the GTX35.. but I have only experienced a 320kw gtst pulling form 4000rpm.. so hence my question.... I thought that was pretty ok really ..that is the little wait before the storm..

What do you think is optimal

Whatever is fastest against the clock

Would suck if it was just a bad tank of fuel.

woukd have to be many bad tanks of fuel...

The motor works fine, the exhaust is being tweaked and the turbo ?? Maybe the manifold could be the problem for the turbo??

It is full boost now at 4600rpm and then starts to loose boost, I want it under 4000rpm and to maintain the boost and do not think that should be too hard to get.

The manifold may come on Tuesday and if it does the work can be finished and the car tuned.

So I will wait and see

why you want bottom end so much pete? you got such a good engine build and revs to 8000rpm why not just bolt something that would kick ass from 4000rpm onward like a GTX35 cause the 3.2L should be fine as is for bottom end, then you could go to track and use 450kw's to have your fun...

It was not being built for the track.

I do not care if it is 300kw as long as I can use the 300kw as a DD, a street car that does not going until 5000rpm + , in "my mind" is a waste of a good car.

Do not get me wrong, even the way it is now, it is a fun car. It has a linear acceleration that handles easily on corners. Blokes talk about too much torque but the right foot takes care of that and your brain takes care of the rest.

This is what I want, being at full boost before 4000rpm, it is 4600 now so I think under 4k should be easy to get considering some of the problems I have had with the build once the problems have been sorted

[XKLABA]

What do you think is optimal XKLABA? Will vary from track to track obviously but interested to know based on your experience.

It really depends on the car and how it is setup, suspension tyres aero etc, it also depends on what kind of HP it makes, stock car on road tyre would be a hand full at around a genuine 350kw, my 34 has R tune suspension, sway bars and biggish brake upgrade and 295/30/18 Hankook Z221s in soft compound and I find about 380kws is controllable and could probably go to 400kw with some more practice on any given track

If you have Steve Ka's WTAC car then by all means go 450kw or more

I have not done any track work, what do you find happens after 380kw? Is the power too agressive?

[XKLABA]

You end up spending more time fighting the car to keep it straight then putting down good lap times

I went to the drags last week for shits and giggles and it had no tractions 1st 2nd and most of 3rd on 24psi which is about 440kws on a prepped track, now imagine that every time you come out of a corner and try to put the power down one a surface that isn't prepped for extra traction

Can be done don't get me wrong it's just not a fun experience if you are looking for a good lap time, 4WD skids then it is awesome fun, at 380kw I was drifting the fishhook in 4WD when it finally started to work ( not bleed completely so 4WD takes its sweet arse time to activate) at wakefield while peddling it

You take things to seriously.

time to trade for silver c34.

I hear what ya saying, definitely a handfull around corners.

How did you go a drags, what time/mph?

Are you sure ur 4wd is working properly? I only get a but of wheelspin in second, definitely none in 3rd gear

Have you got it set up to basically run RWD until you start pushing hard?

Best that night was 11.1@132mph with a 2.1 60"

Car weighed in at 1682kgs without me and I'm 108kgs

Car has gone 10.8 @132mph with a 1.7 60"

When you feel the front moving sideways as well you can be fairly sure the 4WD does work, eventually lol, it still needs more bleeding, it is just been a PITA this time for some reason

[XKLABA]

Nah mate, it is still all factory ATTESA just I put a bolt in the back of the actuator to remove the free play in the actuator arm and haven't been aboe to get all the air out properly yet

[Hadouken]

Happens to me aswell at the drags.

Much fun

[XKLABA]

I'm putting on my 265/35/18 Z221s on the car and going back this week for another go with some of my RTDC team mates

[Hadouken]

And so you should. Should take video.
