Dyno figures

[GTS-t VSPEC]

Kym,

As I keep telling you, you need to get it on a dyno, to see what is wrong, we are currently guessing what the problem is, we need to monitor alot of factors to tell you what to do. Yes those two things may help, but then again it could be related to something else.

See'ya:burnout:

I know this hey, i'd rather exhaust every other avenue first tho' trying things here and there..

I now have in my posession, an EGO meter to have a play with and have a look-see...

[macka]

Standard bovs LEAK thats why we put after market ones on

Unless your gay then you just put one on that gos choooooooooooooooooo

Strich9 buddy! Dont stress about your Air fuel ratios man, I have to wash the back of my white line every 2nd day and shan gets watery eyes after a few mins of driving behind me, thats if i havent burnt his bonnet by then

Rev i got 250RWHP @ Myaree on 10psi pod and cat back, EBC lol

My last dyno at SSTs seemed very harsh i only got 286hp @ 16psi but partly due to turbo and timing issues

[N I B]

It is near enuff 240 psrwhp.or 310ps Flywheel.

But the real piont is he got a good gain with a lot more

to come with a few small changes which justified his

out lay I'd say.

Steve... I kinda asked this when I was there last night but didnt get a chance to find out properly.... Are you able to tune my AVC-R on the dyno down there at SST??? I will need someone to do this after I have run my new clutch in ( Say in about a week or two's time )

Thanks

[GTR King]

Good to hear. Good power for little $$$

Sounds good to me :]

Although sounds to me like Intake from filter restrictions is gonna be an issue so try for better twin setup if u can fit it in. Otherwise anything more may be in vein.

[rob77]

Little $$'s??? I've spent more money than most people who have done their fmic, I did buy a trust unit remember. The whole idea of the trust cooler was to improve intake temps in order to reduce pinging (and I can run 12-13psi all day everyday even in 30 degree heat) without the car pinging. Once I get this AF ratio sorted then I can start mucking around with the timing, like rev210 is.

GTR King,

I haven't seen many twin setup's on a GTS-t, can't see the advantage of that, but a less restrictive pod is on the cards.

See'ya:burnout:

[N I B]

Twins are no good with a single AFM and $25 Xspeed jobs

have been the best so far any way.

The rest of the exhaust will be the go first then 13psi all

the way and 200kws will be on tap no worrys.

Just to clear things up. Speedworks dont actually have a Dyno. The dyno belongs to Automotive Power Analysis and resides at JRT in Bentley.

As for Rob's figure? We were all scratching our heads on that one during the dyno day! It was a freak run which seemed a little out considering the other 30 cars done during the day produced their expected hp figures. Including mine.

I dont think the dyno is "high reading" as such. Perhaps a setting was incorrect, we did noticed that it being a hub dyno it was extremely sensitive to diff ratio settings and could calculate way out of whack if it was even slightly out.

Oh well, like VSpec says... just as long as you use the same dyno for your benchmarking, you cant go wrong

I'll be going to JRT one afternoon to dyno the car on the dynapak again, so I can get a before and after dyno with the cooler.

[giz01]

Did your car run that 1/4 time with the 273rwhp? if so why is the mph so low? my gf's s14 ran 13.7@102mph (willowbank)with only 170 rwhp! mates 300zx TT ran [email protected] with 280rwhp(willowbank)300's are alot heavier than skylines!

[rob77]

Its 273ps not hp. its about 270hp. We're not sure why the dyno read that figure, it was a crazy figure considering what was done to the car at the time. A supra also pulled an odd figure too and everyone else on the day seemed to pull normal figures. I'll be going down the drags sometime soonish and hope to be around the mid 13's.

[GTS-t VSPEC]

giz01, the power is not as important as how it generates the power, now with the boost and FMIC I think rob should easily get a 13. Some cars with more power are getting slower times due to wheelspin and lag etc, so power is not always directly correlated to fast 1/4mile times.

See'ya:burnout:

[giz01]

yes & no i think you will find that mph is one of the best indicators of hp cause you can wheelspin quite abit & still get a big mph or a crappy launch eg bog down & still run big mph! yet this will affect your et but not mph!

"Dyno proven" is a bad mix of words. Dyno tuned or Dynotested

maybe. In the new issue of Perth street car there is a good

example, A Falcon "Dyno proven 502rwhp" STD internals?

and runs in the 12s on slicks mmmmm sounds suss hay.

On Tuesday I had a BIG Valiant 6Cyl non turbo or NOS

make 305rwhp with spectators here saying i tricked

the Dyno and was bull shitting them.

Last nite it ran 11.5@ 114mph full bodyed and 1400kgs

and a XB falcon road car on slicks 293rwhp 12.2sec.

The 1/4 mile should be used to see if your shop is fudging

power figs. "Dynos can lie"

"TRACK PROVEN" is the only true way of proven.

[benm]

Removing the standard frontpipe and replacing it with a 3" pipe should give u around 7-10rwkw extra.

Take a look at my thread here

[rev210]

I agree steve.

After all the dyno is just part of the tuning process to get the cars real perfomance when doing the thing you love to do the most... racing!

I have found some tuners do the final dyno tune with the bonnet 'up'. This goes for power runs as well. Although there is certainly reasons of keeping the engine 'cool' for long periods of tune, the final tweaks and power run ought to be done with the lid down I reckon. At least I have asked this in the past- with some strange looks given but, I feel a better tune results.

I could be wrong but, the car doesnt get driven around with the bonnet up.

[adam 32]

giz01 why do you keep bringing this shit up? epsecially in the WA section. no-one cares about your so-called mates, and after arguing this point with you for over 2 pages a few months back can you leave your pointless bullshit out of our threads.

[N I B]

Get your cars weighed costs$5.00 then get your MPH from

the Plex get a Morosso etc calculator and bingo no Dyno operator

bullshit you have a good idea of your true power.
