hmmm Saturday I am out your way....

[Mick_o]

Im working Saturday too but should be home around the 4 zone id say give us a buzz and hopefully our timing is good because im curious to see what u think having driven many turbo set ups

hmmm Saturday I am out your way....

Mick - of curiosity what is your max voltage reading on your PFC assuming you have z32 AFM?

[Mick_o]

I am running a Z32 mate but i have a nistune so dont know bout the voltage. Why is that zoom?

just want to compare to mine in regarding to the air flow rate. Are you intending to run higher boost? do you have cam?

[GTScotT]

Did gravity fix your EVC or what Mick?

You never got back to me with a full result

[Mick_o]

Motor is completely stock no cams mate dont know bout anymore boost im running around 21psi now so i think its fairly high for a stock motor lol it did spike up to nearly 27psi for a little while before i noticed and backed off but it didnt ping or anything so should have plenty of fuel with my Tomei pump and 850cc PE's but it did spin my 255's in 3rd gear at bout 90kph haha it felt awesome!

Gday Harry yeah it did fix it mate CHEERS! found some english instructions now so im bout to go have a play with the controller because its still running high for example its set at 15psi on the controller now but goes up to 19-20psi but its stable and not spiking like it used to so i think its to do with the boost offset settings or the likes but ill be back on soon when i have play and take her for a squirt

with cams it will bring your boost on earlier and give you atleast 10kw everywhere. Yeah, i've been running 20psi with gcg for the last 5 years and now with the gtx i'm running 23psi on the stocker. Finger cross! lucky i don't drive alot. Maybe 255-275 semi slick time for you!!

So what is your rpm when you hit 20psi?

[Mick_o]

Haha yeah i dont drive mine much either ive had my car for 12 months now and done about 2500-3000kms. In second gear its bout 4000rpm and it really starts to haul ass all the way to 7500rpm 3rd is probably around 3700rpm maybe slightly less been seriously thinking about poncams to help with lag because after being used to the 200kw and stock turbo response the lag was really noticable even though it drove much nicer off boost though i must say! But when it comes on now my smile is probably 2 inches wider now its simply alot of fun to drive now. So if i could get it boosting earlier it wouldnt really be that far off stock response that would be UNREAL!

Believe it or not my car doesnt really spin wheels mate even in 1st gear when you put your foot down! it just hooks up its awesome! When my boost controller settings are sweet ill probably put 25psi into her briefly and see how that feels or get an E85 tune which i initially was gunna do i love it!

cams aren't going to bring boost on sooner

[Mick_o]

Really? Have always thought they did!

Mate that is a sight better than what mine did the other night and ever since I put it down in 3rd. It slipped the clutch and smashed the limiter as soon as it came on boost in 3rd. Even driving from no boost to full boost it starts to slip.

You must be stoked with your car now, I know I am with mine (apart from the clutch) My grin is just like yours

More lift + more duration = less gas velocity at low revs

So even if the actual RPM that max boost is reached is lower, the car will have less power off boost

[Mick_o]

Thats bit of a bummer mate but once your clutch is sorted the fun will begin good luck with it!

Yeah i am stoked with it but she only fried 3rd when my boost hit 26.6psi haha on 21psi it just sits down and boogies i love it!

My blitz gauge only goes to 1.5 bar and i watched the needle fly straight to the bump stop! the motor didnt make any noises it shouldnt but i backed off anyways lol!

The smile is what its all about mate and if your smile is like mine you are very much a happy man too

Something that does help is VCT, don't think it brings on boost any earlier but gives it more off boost pull.

You could do something funky with retarding the ignition timing massively as that will get you boost in idle, but you'd want it switch controlled otherwise it will be horrible to drive and f**k you economy.

Well i dont want it any doughier off boost so that rules cams out for me! It feels good the way it is and once my tune is finished it will be better!

My car is a 97 33 so itd have vct yeah? I bought HKS cam gears and timing belt which arent installed is there any benefits to installing them apart from them looking pretty in my engine bay??

Its not as simple as doing this, you wont make boost on idle, the engine just isn't producing enough exhaust gas just sitting there. Rally cars that have anti-lag require a fair amount of revs and basically misfire certain cylinders and play with fuel and timing. It's not real great for the engine either I dont think but they throw a new engine at the car every rally

All R33 GTS-t's have VCT

[Mick_o]

I thought the anti lag set ups worked by basically pumping fuel into the exhaust manifold? I guess thats just probably 1 of the set ups they have played around with
