Just dynoed my Car

[sik32]

Well my car just dynoed 212kw @ 18psi.

My mods include:

Microtech LT-8

Custom Frontmount

3.5 inch dump to cat 3 inch for the rest

Hyflow T3/4

h/d Clutch

Vl pusher pump as well as standard intank

Standard air box

Well i don't know what everyone else thinks but this seams a little low for the modifications. I though atleast 257kw because have beaten a certain silva with a rb20 before.

The dyno was not in shootout mode and had a ramp rate of 100

[rev210]

Did you dyno it with the bonnet down?

Thats the best way to get a more realistic figure. It is always a lower figure too.

I wouldn't worry about the figure if it was an improvement.

The real measurement is beating that 'certain silvia' and doing some quick times around your favorite circuit or drag strip.

[sik32]

The bonnet was up on the dyno. See now i dont know if it was my auto diff that made me win or the power of my engine????

I dont think the differance of 45kw between me and the silva was in the diff.

It's just got me thinking about the accuracy of the dyno.?????

[ed]

does it matter how much power you make?

as long as you beat 'em its all good

[TTT]

maybe the silvia owner's dyno figure is the incorrect one??

[rev210]

Stop getting all hyped about the dyno figure.

It's a peice of paper, just like toilet paper its only fit to wipe your ass on if its not being used to help tune a car.

So what if the silvias got a better dyno readout. Scan yours into the computer and change it with photoshop to read 1000rwkw, then you can beat him at the races AND in a dyno paper stand off!

[sik32]

Yes you can say i'm a little focused on the dyno readout, I guess 212kw is not enough. The tune on the car was pretty S&*t, as soon as i gave it a boot full it detonated the loudest i have ever heard it. Sooo in 2 weeks it will be going back on the dyno, the same one as the rb silvia.

I'll let everyone know how it goes!

Hi sik32, is this an RB20DET? No adjustable cam pulleys? No injector upgrade? No adjustable fuel pressure regulator? No internal mods? Standard camshafts? No pod?

If it's a roller dyno (not hub) 212 rwkw is 360 bhp, that's pretty good for an RB20DET with the mods you have listed. I'm surprised it didn't run out of injector capacity.

I sort of agree with the other guys, except I reckon the dyno might be a bit optimistic.

PS; let us know the dyno shop that the Silvia runs on, I want to take my car there and get a good bit of paper to wipe my butt on as well.

[rev210]

apparently the paper they use at that dyno is three-ply extra soft.

[adam 32]

yeh id be happy with 360bhp on std injectors and std AFM - thats about right for the mods youve got

[sik32]

All the mods I have on my car are listed. They also said i had enough fuel for just over 300hp.

i cant wait to drive...

join ryan in line! :bahaha:

u wont get 257rwkw without upgrading your injectors and fuel pump and more boost.

[uLa32]

3 ply for extra strength... coz sometimes your fingers go through

Microtech LT-8

hey sik32,

I'm too am running a LT-8 on my recently purchased GTS-4.

Just wondering how you find the driveability of it in your RB20?

How's the economy if your just cruising along in 5th gear?

I don't think they have closed-loop cruise mode. So they don't use the oxy sensor, do they?

What about initial start-up?

I know the LT-8 doesn't use the idle stepper valve. (the thing on the end of the plenum) So do you have some sort of air by-pass valve to compensate for the greater amount of fuel at start-up?

I'm just asking cos I find that mine never starts cleanly especially after I haven't driven it for a day or so. Sometimes it even seems like it wants to stall itself cos of the lack of air (revs drop below 500)

As far as the economy on my car, it pretty bad considering that I hardly ever boost it around town. and I spend alot of time cruising in 5th gear. something like 350km to a tank:(

I haven't had a chance to dyno it yet but hopefully will in a few weeks.

anything you can enlighten me on?

[sik32]

ok Interloper, First of all I find Microtech a great computer if you are on a budget. Drivability is fine, as it drives like the standard computer, but there is a few things that dislike about my Microtech. Cold starts, the car sometimes stalls on the first turn of the key and will not idle properly until the car has warmed up properly. This seems to be a problem that most cars with microtech have.

Fuel ecomomy, well that went out the window along with my standard computer. Microtech is Very bad on fuel, this also may be caused by the tuning as I like it too be a little fat. Even when i'm off boost and on the highway it still sucks fuel like no tomorrow.

Yes approx 350km. If i could do it all over again i would chose apexi or motec because of money i have wasted on fuel i could have afforded either of these. No Joke

Good luck with it all:D

Ps thanks for the toilet jokes guys!!!!!!!:bahaha:

Here's a pic of my car

[sik32]

mmm

[Interloper]

lol, would you believe that my GTS-4 is also burgundy!!!

what a hard case to find another 32, same colour, running an LT-8...

BTW- do you have a hand controller for it? and did you use it for tuning or a laptop?

[sik32]

no i dont have a hand controller(would like one) and didn't find a laptop in time when we tuned my car

Yer burgangy is the best factory colour. hehe
