Dyno figures

[rob77]

Last time I was @ SST for a dyno, the car was stock (completely, not even an aftermarket exhaust or pod) and managed only 97kw@wheels, after fitting a c-red apexi n1 lookalike cat back exhaust it rose to 115kw@wheels (small advance via the CAS). Since then the blitz spec s EBC has gone in, a HKS green pod and now the trust fmic and my cars pulling 175kw@wheels (with no pod, the HKS unit is leaning the fuel curve out a bit too much at the top end, might go for one of those $25 hurricanes). An interesting fact as well is my EBC (for some odd reason... gonna have to get speedworks to check it) is not holding 12psi of boost (though it reads it). At around 5500-6000 (when the valve timing cuts in) its dropping to around 9psi. So with a better pod, a bit more advance (as the cooler is doing more than enough keeping intake temps down) and the ebc holding 13psi flat it should crack 200kw@wheels. Either way I look at how much money I've spent I think its more than worth every dollar. I'll also be looking at the dump+front pipe soon too, as thats causing flow restrictions. So I've picked up 60kw@wheels, thats over 50% more power... although I've spent a fair bit, I'm sure you could get simular results spending less too, just look at rev210, nobody's been able to beat him yet with a stock turbo or intercooler

nice work man

now all ya have to do

turn that into a good time down the quarter!

rob,

It was quite a decent power improvement, I'd suggest the dump pipe would be a good idea, cause the exhaust will limit how much power is produced. Still it was a good improvement, and nice to see that your money has paid off.

VERY nice rob! 175kw atw is nothing to sneeze at.....

Kinda makes me wonder what my car can pull on 12.5psi of boost, i've pretty much got the same as you, 'cept the new cooler of course.

POD, zorst, boost (10-11psi)

I reckon I could up the boost to 12.5-13psi without it pinging....

gotta organise that dyno day for SAU and see what figures people get!

[GTS-t VSPEC]

It was an impressive gain, and only took about 5 minutes all up really. The pod filter that rob had on was restricting the airflow quite badly, and with it removed the air/fuel ratio was just about perfect.

HAd my car dynoed last week at SST .

First run was 250 with the HKS POD FILTER ON .

Was running at 12.5 a/f ratio which is ok , but steve rekons thats a bit too lean.

Took the HKS pod filter off and it ran 252hp at 11.5 a/f ratio which is spot on he rekons.

Good work although i seriously doubt you will get 200kw at 13psi on ssts dyno.

Your not losing boost from the EBC thats what they [email protected] boost!

You dont have a dump pipe yet that will restrict boost id be looking their first..

You must be deep into the 13s now Rob

Oh..I still have that TRUST Front pipe (not dump) 3 inch ive just sandblasted and painted it, someones looking at it but hasnt gotten back to me yet $200

[GTS-t VSPEC]

Yeah Simon, that is exactly what happend last night. Remove the HKS Pod filter anf the A/F ratio was perfect, even if only a marginal increase in power, less chance of pinging.

I take it your figures are in hp, not kW:p

What sort of ecu remap have you got?

I've heard that the R33 can use a remapped R32 ecu if you ditch the VVT.

good power dude

yeah the hks filters aren't to flash when they get dirty.

okay i'll be the bastard whats the conversion for KW to PS

cause that still seems along way form the 273.5 u pulled on speedworks dyno.

[GTS-t VSPEC]

The reason rob went back to Steve, other than the offer of free dyno run, was that he had previously had a run on there before and so could accurately guage the power imporvement. It doesn't matter who's dyno you choose aslong as you stick to the same one. It's not the final power that impresses anyone, it's the increase from you mods on the same dyno.

To go from 115rwkW to 175rwkW is a huge improvement, and with a few more simple mods to go could get close to the magical 200rwkW.

i know that i'm trying to gauge how the speedworks dyno reads

yes its great improvement. 60rwkw with front mount and boost and pod is awesome.

if he goes for the SAFC i he should see another 45rwhp (about 30kw) which would be close to the 200rwkw.

[GTS-t VSPEC]

He really needs to do the dump first, his boost wasn't holding very well, it dropped to 9psi after the NVCS kicked in. His fuel ratio is perfect so an SAFC might not do much.

See'ya:burnout:

[skyzerr33]

u'll be surprised what the SAFC will do, and still keep his fuel ratio perfect. but i agree the dump should be the next priority

[GTS-t VSPEC]

But the AFC just control's the signal from the AFM to the computer, if the A/F ratio is fine what can it do?

If your after 200rwkw then just go to myaree dyno, if 200rwkw is the magical number then myaree must be the most magical place on earth!

[GTS-t VSPEC]

Yeah, that's funny, and true, but I think 200rwkw on SST's would mean more. It is still a number to aim for, even if it doesn't mean much. Shows that the mods are working in the right direction.

So what some of you are saying is that restrictive PODs can affect A/F ratio's.

One would think that my car running rich as hell, by removing my filter and reconnecting the stock BOV, i'd get a better time ?

The excess air being dumped from the blitz can't be good for A/F ratio's right ?

Help me understand!

[GTS-t VSPEC]

The pods are reducing the cooling effect on the hot-wire(AFM) and therefore the fuel ratio's are on the lean side. This can all be fixed with an S-AFC of aftermarket computer, but changing pods is a cheap alternative.

The stock BOV's are fine, and can be used even in high horspeower apps, they also help reduce compressor surge. I never had any issue with my Blitz BOV, but many people do, as it confuses the AFM into thinking it needs more fuel, hence why peopl have stalling problems.

Did that help?

[ix9]

So you say it'd be worth a try removing the POD, and re-connecting the stock BOV, to see for a better time ?
