Tuned Alloytec 190 Performance Issue?

[mrdunu]

I just got a VCM tune from CHE, and as you can see, my max stock power was 168.6 HP. Does this seem too low for an Alloytec 190? Everything is stock on my May 06 VZ Calais, except for the two hole mod and a k&n panel air filter. Though I think it may be because of the fact that I'm using Standard Unleaded Petrol (i.e. not E-10). What do you guys think?

[impulsesv6]

i think it is what it is...

you just have to deal with it...

my car is "low" on "dyno" power but supprisingly quick down the 1/4

[mrdunu]

i was hoping that i'd be able to hit the 200hp mark (like all the other equivalent alloytec 190's) with this tune, but i guess my "stock dyno" power really felt like a slap across the face =/

[impulsive]

20hp gain isnt too bad?

[mrdunu]

no no, im not talking about the tune. the 20hp gain was amazing, i was just hoping that my stock power was 186 hp (maybe im getting a bit greedy?)

why would you use e 10 in a vz 190?

Mate dont be too worried. I got almost the same figure this is with headers hi flow cats and cai and plenum spacers wit 98 ultimate fuel. They are a hit n miss but still a good engine.

[WogBoyz]

maybe try a 98 ron fuel and possible a full exhuast, that should get ya closer to 200 with a retune to suit to get the most out of it

[mrdunu]

i don't, but some people do given that its E-10 compatible :S

really? that sucksssss. i would have thought after spending THAT much on the mods you've installed, you would at least get some decent power from it!

Dynos can read different numbers depending on the day and weather conditions etc. Let the 1/4 mile determine the performance and not the dyno. The dyno is an instrument mainly used for tuning. Some people can have lower dyno figures than others but run quicker down the 1/4. Other factors such as when the car makes the power in the rev range, how much torque and how its spread over the rev range etc etc.

Run your car down the strip and see how it goes. My totally stock 2004 Auto VZ Calais Alloytec190 did 15.3sec down the 1/4 with 2/3 tank fuel and me ofcourse Some people who have had tunes, headers, exhaust, modified air intake only gain .5 sec quicker than my time. I personally would want a better gain than this for the money outlayed.

Otherwise if performance gain per dollar spent is more your style, then maybe choose a different engine eg 5.7lt or 6.0lt, RB30 etc. Because as said previously, these engines are hit and miss. The results are what they are. And these engines don't respond as well as many others out there would to the same modifications.

Goodluck and lets us know if you do go to the strip

thanks HoldenOnn for the post, really appreciate it

i don't think i'll quite go for the v8's just as yet. given that i'm male, under 25, and have already been in an accident (which wasn't even my fault but according to the stupid law it was!), my insurance premium's already high enough!

but i might consider taking my car to the strip one day, the emphasis being on one day though.

though my car does rev/accelerate harder, and produces an amazing induction roar after the tune, so I guess it was all worth it in the end

[monaro327]

that seems to be what most stock alloytecs make on Dale's dyno.

why would you use e 10 in a vz 190?

Or any VZ, actually.
E10 is a fuel option the Alloytecs can handle and is worse in terms of economy than ordinary unleaded.
I never used anything other than PULP95/98.

[richardpalinkas]

maybe he meant E85, not E10, as that would make sense?

[Little Red VZ Go-Kart]

But if it's performance he's after, E10 or E85 is best forgotten. Doesn't make sense to go through the expense of the tune then fall back on ULP. PULPxx (PULP especially) runs clean and hot and will provide noticeably chirpier start-off. I'm getting 9.8L/100km in PWR mode in my VZ on PULP98 which is only slightly worse (those improves considerably over longer distances) than the benchmarked 7.8L/100 on ULP in non-PWR mode.

yea but maybe he thought, and just a thought lol, that E85 is superior as they use them in the V8 supercars. i dunno, maybe when he responds we will all know what he was talking about

[Little Red VZ Go-Kart]

"they use them in the V8 supercars..."
What? Yikes! Do tell us more about the Exx evil concoction! What are those boys pouring into their good ol' Holdens for the podium finish!? Avgas!?

V8 Supercars - Wikipedia, the free encyclopedia

just incase you were serious, its under power lol

[Little Red VZ Go-Kart]

Waaaaait....
Metho...sugar...corn...whey...cheese...biowaste (!). How...innovative, and the alloytec will sip it with aplomb. A great economic stimulus for the farmers, methinks, but how much of the Exx stuff is actually consumed in Australia?

But I'm sticking with PULP95/98.

[richardpalinkas]

lol yea i reakon

[mrdunu]

just to clarify, i'm not using the cheap economical E-10 fuel. I'm using standard unleaded petrol (otherwise known as octane 91). The reason I went for the tune was because i wanted more "oomf" from the car off the line, and given that my 'rents were paying for my petrol expenses, I didn't want to tell them that i modified the car further (i.e. they don't know i tuned it).

[mrdunu]

and by the way, how the hell are all of you managing 7.8L/100km's with ULP. I'm getting roughly around 14-15L/100km's without flooring the car and driving around like a nut.. but then again, the majority of my driving is city driving (i.e. stopping and starting).

[Little Red VZ Go-Kart]

People eyeball and often deride me as a "bachelor boy" for driving a "bloody huge car", not realising that this car returns better fuel consumption than their own, additional of course to being able to move mountains of gear for bushwalking and cycling at the drop of a hat.

Regarding economy, my routes are regularly the Geelong-Melbourne (tomorrow, Thursday), Geelong-Ballarat and Melbourne-Wangaratta (Saturday) runs, where it routinely returns 7.8L/100km on PULP98 at 100 to 112km/h. This is the same as my sister's ASTRA CDXi auto "taxi" with raspy ecotec engine running ULP. I do not need to "floor" the accelerator; curiously, only a very light touch of the accelerator is needed from start and only slightly more to 100. Cruise is routinely engaged on freeways.

Around town stop-start is avoided in my case: I walk, use a bus, either of two bikes or go with somebody else as needed. City driving is just terrible and economy of any car suffers badly. A figure of 13-14L/100km is common and wasteful.

Another reason for your high fuel economy could be the mods.
