haha lout, that looks like a lot of fun. What are the specs on your wagon? I’m a brit so I have no idea about Aussie wagons - is that a Holden Commodore?
voltron’s - are you talking about your own CTS-V 550whp wagon? If so, what’s the mod list? Or is that hennessey at ATCO? Either way look forward to it, maybe I should rename this thread the “domestic wagon” thread.
I think Matt’s car is a mildly modified sedan. The wagon is another forum guy. I think he also has an absurd RS6 if it’s the same guy I’m thinking of. His signature on the Cadillac forum has some absurd dyno numbers for his Audi.
It’s a 1987 Holden Commodore Wagon. This particular model has the 3 litre, 6 cylinder engine in it. 5 speed manual and 4.11 diff at the rear. It’s currently on it’s second engine and gearbox.
At the moment it’s a little worse for wear and needing lots of TLC including a new paint job which includes a particular blue.
well, we’ve all seen it before. The guys who love the dyno tend to avoid the dragstrip as it’s a real ‘moment of truth’ to coin AWE’s silly phrase (their dyno reads higher than any I’ve ever seen before, so it’s ironic that they have that big ‘moment of truth’ sign above their dyno. Maybe they should edit it to ‘moment of an inflated and irrelevant dyno reading if you plan to compare to other dyno readings’. That tendency to prefer the dyno to the dragstrip often goes for many tuning companies as well.
The problem with the dyno is it doesn’t reflect the dynamics of the tune…in other words a car can dyno great, but perform nowhere near as well. I mean if you dyno great but your car doesn’t pulll on the street, what’s the dyno worth? You going to pull that out as ‘proof’ that you should have won, even though you just lost? We saw that with the Giac tuned VF supercharger…it had 0.2-0.3 second of lag in every race, and when it engaged each gear thereafter it also lagged. It dyno’d 402 whp though lol. We also saw it with the APR RS4…it dyno’d like 430-440 whp, but ran only about 2 tenths faster than a stock RS4. It was the tune. When JHM re-tuned one of the APR cars, it picked up 0.7 seconds and 9 mph. That’s crazy. When APR dyno’d that new tune, it was quite a bit stronger, but not crazy…it just revealed how bad the APR tune was.
Racing car vs. car is the only real measure I care about. Since that’s just about impossible as we’re all over the world, a standardized performance test over a standardized distance with audited timing/testing equipment and a certification process covered by one governing body makes the most sense to me. That’s the NHRA approved dragstrip.
It’s funny you mention all of this because in the land of the cts-v any yocal with a dyno can tune these cars and throw around peak hp and tq numbers to sound good. The differences in 1/4 times are staggering in many cases from shop to shop for cars with similar peak gains.
I learned from my mistakes with the S4 and took my time to find the right tuner for this car. East Coast Supercharging is what I came up with. They tune the fastest Vettes in the world and are in central Jersey. They also sponsor the Vette challenge at Atco and the owners car is ridiculous.
that’s great to hear VH. I don’t know if I tried to help you back in your B8 S4 days, but I often try to get guys to sit back and be patient…let the tuning companies PROVE the parts work at making you faster by going to the strip. It’s fucking easy to go as you know, having been 5-6 times in a year. So why can’t they? When APR took 12 months to go to the strip with the APR RS4 SC…we knew it was a flop. WHen they got it JHM tuned, they went to the strip right away and announced the 11s times as they rolled in. Anyone get the feeling they had already gone on the old APR tune and run high 12s?(sakimano raises his hand).
I was literally inches from buying a VF supercharger kit for my B7 S4 in late 2008 before a few guys who post here on this site told me to wait…there was more to the VF story. VF showed us dynos of 396 whp, i.e. 130 whp over stock. They said it was fast…it pulled on ‘insert fast car here’. They had people attest to how awesome it felt. They lent one to a forum member so he could post a glowing review (‘but no timed acceleration runs as we’re still finalizing the tune’). They even paid a forum member to put the kit on his car and take it to shows and events, and gave him kickbacks for further kit sales. He told nobody about it…it was guerrilla marketing.
They did absolutely everything you could ever think of BUT test the car at the strip, and that’s all I wanted them to do before I agreed to be the second VF beta car. They never did. They said the clutch wouldnt hold the power. They said they needed to wait for a special clutch. Then the clutch came in. Then they said nothing. They went deathly silent and refused to followup. December 2008 was when I asked them over and over for dragstrip times on audizine after the supposed clutch swap. They never EVER posted again in the B6/7 S4 section.
Then the company motto was ‘these cars aren’t made for the dragstrip’. Something I’ve learned over the years…when you hear someone say this, it’s either a tuning company whose go-fast parts aren’t worth SHIT…or it’s from a customer who has just bought a bunch of go-fast parts that aren’t worth SHIT.
