I thought my car felt a lot quicker today so I decided to do a 1/4 mile run with my Beltronics Vector. My best run in the summer was a 0-60 in 7.23 seconds with the 1/4 coming at 15.85 seconds.

I'll let the pictures do the talking:





The launch was the hardest part with it being so bloody cold but I got the tires warmed up enough to stick and get a good run in.


What I want to know is can anyone figure out how much horsepower the engine is making given these specs?

Hey...where is larchmont. Can this put to rest our cold vs hot debate?

larchmont

I thought we already did.

Although I still wonder.

BTW....Dan, do you have the MT or AT?? Pardon me for not knowing!
I woulda thought for sure it's MT, but I actually checked "Who Posted" on the MT "check-in" thread, and it looks like you're not on there, so..... does that mean you did 6.95 with the AT????

Also BTW, not to be too anal and worry about two-hundredths of a second..... but the thing says 6.95.
So why are you saying 6.97?

Lung Fu Mo Shi

He's Canadian?

Dan Martin

Yes it was the MT. And I goofed on the title. My 3rd run was 6.97 but the best run was my 5th @ 6.95 seconds.

Dan Martin

I might have a touch of mad cow disease..... :busted:

dom

Yes, our clocks work differently up here in Canada

Dan, what exactly is this Beltrinic Vector and how accurate are they? and how does it work? The fact that the same unit got you a 7.23 in the summer definently puts that cold vs hot debate to rest.

The Beltronics Vector FX2 is a G-Force meter that can accurately measure cornering forces an acceleration rates. It does 0-60, 1/4 mile, and 60-0. Road and Track did an article on the FX2 about a year ago and they found that the accuracy was actually better than what the manufacturer specs show. 0-60 and 1/4 mile are accuate to 0.05 seconds.

I'll upload a better picture of my setup when I get home tonight.

Is this stock?

Dan Martin

Yep.

I was running 94 octane but I was also running 94 octane when I did the 7.23sec run in the summer.

TinkySD

Did you do it over the same stretch of road? I don't know about your model but in general accelerometers are easily thrown off by minor changes in road slope. Did you make a two way run over the same stretch to cancel that out?

I'm not trying to be a pessimist or anything just wondering as they could be confounding factors.

larchmont

Great questions, Tinky.

But regardless, both the summer and winter times that he got are PFG. I'll take either one. And I fully believe both of them.

Dan Martin

Actually purely by coincedence it was on the same road. We have a really long straight road behind the office that isn't used by anyone but us so I tend to use it for any performance tests. I didn't do a run in each direction but it really shouldn't matter because it's totally flat. I can drive from end to end and the the g-meter won't change more than 0.02g the whole way. It was paved only a year ago so there really isn't any bumps or anything else that could potentially influence the test. Beltronics has added a lot of filtering to the FX-2 that compensates for normal road variations. It also recalibrates itself before each run so as long as the grade remains somewhat constant througout the run it won't affect the results.

Hey Dan, do think your car might be more broken in than in the summer?

KJLite

I think the performance is difference is more relted to the car being broken in more now, rather than due to cold air.

I believe those figures. i tested my car with a digital camera recording the dash, and estimate 7- 7.5 sec.

BTW, do you have the vector adjusted for vehicle weight, Cd, etc?

i have been thinking of purchasing one, and wanted to know if you can increase the accuracy by adjusting the variables per car.

Dan Martin

That's entirely possible, but I had 3000+ KM in the summer and I'm just a little over 6000 now. I guess I'll have to do another run next summer!

Dan Martin

The weight and Cd is used mostly for horespower measurements. I've entered the weight but I don't know the Cd and frontal area of the TSX.

There is an adjustment for rollout which is the distance you travel before the clock starts. This makes the biggest difference for the 0-60 times. I've set it to the same settings you would have at a drag strip so the numbers should be comparable to the ones in the magazine (i think it's 12").

iamhomin

Great numbers!

Have you done a test with your intake?

dom

Another thread, brought back from the dead.

But I wonder if Dan has re-tested with the Injen?

biker

Holy resurection!

Dan Martin

I haven't retested with the Injen intake because I removed the g-meter before I had my center console replaced and I haven't reinstalled it yet. I was actually going to do it tonight because I'm curious what gains I'll see. I ran 7.2 0-60 when it was around this temperature last year so I'll use that as a baseline.

iamhomin

Nice, btw, where'd you purchase the G-meter?

Wow...Dan broke 7 sec in the 0-60 without any major mods. Nice...

Dan Martin

Mine came straight from the factory which is like 5 minutes from where I live. I think they sell them at Circuit City in the US though.

RMATIC09

Those are nice numbers, sometimes i feel my car can pull the same ,

joerockt

Dan, how did you mount that thing?

jlukja

You talking 0-60 kph?

Dan Martin

It's in my CD storage bin so I can close the door to keep it out of sight.

Dan Martin

nope.

joerockt

I saw that, but how did you mount it to the bin? Brackets?

Dan Martin

I just removed the suction cups from the bracket and screwed it into place.

joerockt

Very nice. I think I want something like this. Gadgets are phun

Dan Martin

for gadgets!

Me likey gadgets. I have too many though, so I'm gonna have to start getting rid of some.

TSX Hokie

Dan, does your gadget do 60-0 as well? It would be interesting to switch tires and see how the braking time changes. My theory is that the TSX would brake alot better with decent tires.

Dan Martin

It does do 60-0 but I haven't tried it yet. You have to configure something in the menu but I'll try it out sometime.

That's a good theory and I think you're correct.

That seems to be the concensus. The stock tires just don't cut it.

It's that time of the year again! (cold)
