Dyno time at last !

[R32 Zilla]

Its been along wait, but i now have all parts i have been looking for, the new turbo is fitted and my car (r32 gtst) is booked in for a rechip and dyno tune on thursday in sydney.

Last time car was on the dyno it made 137 rwkw with :

large fmic

vg30 bb turbo

standard cat in a 3 1/4 inch system

k&n pod filter

hks bov

11 psi

I now have the following :

bosch fuel pump

nismo injectors

z32 afm

chiptorqe chip (soon)

hks gt2535 turbo

hks dump pipe with separate wastegate pipe

high flow cat.

oil catch can

oil cooler

I hope to make about 210 rwkw or more at about 17 psi (dont want to run over 18psi on standard internals).

I think i have covered everything to make this sort of power, or have i ?

[meggala]

you should come very close depending on how high the dyno reads.

to put it in to some sort of persective you car should run a high 12 if lauched well with that set up

and the motor should be able to handel 18-20 psi in bursts

cheers

btw what size injectors ar eyou going to run?

[R32 Zilla]

iam not sure what size the injectors are. I thought they might be 555cc. They were fitted to the same engine that the turbo was.

I thought u may be able to tell me what the most likley size of them would be. They r Nismo and r black and yellow and the only numbers on them are A46-00 .

?

[meggala]

they could be gtr injectors do you have an ecu to tune them and the afm cause the stock one wont handel them.

meggala

[R32 Zilla]

The injectors were sold to me as Nismo injectors so it had better be what they are !!!

As far as i now a fully reprogramed standard computer done by chiptorqe will handle injectors and afm.

Tell me if iam wrong ?

My car is at the dyno today and friday and i have been stuffed around by the people who sold me injectors. I have found out that they ars not straight fit nismo items but they are gtr ones that need alot of work to be fitted as they are the wrong impedence. I have returned them and got my money back but now iam stuck with standard injectors and hardly any time to find some more before car is rechipped. The guys at the dyno are going to try to find some that will fit.

Would anyone have a part no. for mazda 550's that have high impedance ? and will these bolt straight in ?

Where in sydney could i buy them ?

Thanks

Tim.

[meggala]

go to my website http://meggala.com/partslist.html

now you know why I asked all the questions cause i have been down this path I know what it involves. the high impedance rx 7 series 5 injectors should fit. good luck finding them.

they have red tops.all the info is on that page.

btw I hope you have a z32 afm or a fuel cut defend or else you could still be limited to how much hp you make

Thanks meggala,

yes i have a z32 afm being fitted.

i will try to find seires 5 injectors.

Pic of new turbo

and the dump pipe

[meggala]

so what turbo is it it looks nice and fat

[R32 Zilla]

see first post

[R32 Zilla]

My car made 196 rwkw @ 1.3 bar (19.5 psi ).

It would have been good to crack the 200 mark but it is close enough. Dave at SAS, has told me that with the setup i have now it is safe to run that boost as long as i dont plan to circuit race the the car.

Dave allso said that that other rb20's with the same setup and running 1.3 bar normally make around the 200rwkw mark on his dyno. So i think it may read a bit low as i would have expected more power at that boost.

SAS ended up buying and fitting brand new Rochester 50lb (480cc) injectors as 550's of any sort would have been difficult to controll at idle.

Car now goes like a rocket but i have hardley had time to use the power as soon after i picked it up from dyno it developed a boost leak in cooler piping which causes car to miss badly because afm is sending different signal.

What did the injectors cost you as I am going to get series5 ones.

Do you know the specs of the turbo, compressor/exhaust housing size, wheel sizes to compare to my T04e.

Was this the same dyno as you original post because it does seen low compared to other results for both setups

[R32 Zilla]

Injectors were $180ea. yes thats expensive but they are very good injectors and and i didnt have much choice.

Not sure of wheel sizes but exhaust housing is .64 and compressor is .60. (iam going to find out wheel sizes).

The first dynotune for my first setup was done in newcastle at SDT. (137RWKW @ 11PSI )

[meggala]

did chiptorque tune the car for the 480 cc injectors?

good result btw . it sounds like another one of the honest dyno's

cheers

meggala

[R32 Zilla]

Yes chiptourqe tuned it with injectors and z32 afm.

[meggala]

great to hear the beat way to gauge your power is to take it to the drags.

If you can crack 110 mph regadless of time due to traction your car is making big power I made 96 mph @ .7 bar drdrift made 108 mph @ 1.1 bar.

see how you go and if you run a 12 second 1/4 mile your a legend

meggala

[Clint32]

Thanks man, that is very similar to mine, .6 exhaust and compressor housing. I think i will stick to the 550's hopefully they will be fine.

I hope to have my car done by the four six and rotor nats here next year in feburary, hope to run a 12 just like everyone else.

[adam 32]

haha yeh im in the t04e and wanting to break 13s club as well:D

but with skyline traction issues its hard....
