My raceday
 

So i finally got my car dynoed and raced it at the 1/4 mile. Got my car tuned at MAC autosport in parker colorado, did and excellent job of tuning, put down 200 horsepower and 189 ft/lbs torque on a dynojet dyno. Had it tuned for 10psi, however i have not added a helper spring to my setup yet. My turbo would spool to full boost around 4-4.5k at 10psi and then settle to 8 psi until redline.
Getting ready for the helper spring and then get it dynoed again. highest A/F ratio was 12.4.

Raced the 1/4 mile at bandimere speedway in denver colorado.

My best time was a 15.7, and this was the first time i raced, where i quickly learned reaction time plays a big part in getting good times. Rain canceled night so i never got to see what a good run with good reaction time would get.

I dont know how to post pictures or i would put my dyno slip and 1/4 times down
R/T .791
60' 2.7
1/4 15.7
Trap Speed 95.44

MAC and awesome tuning do not go in the same sentence. Their dyno is also REALLY optimistic


/failure

I can't speak for the quality of the shop/dyno, but 200 rwhp sounds about right for 10 psi. Is this on a Greddy or what?

if you have a 240sx and want to be into mad dorifto, well then it's the place for you.
it's also the only 4 wheel dyno I know of in south denver so the audi club meets there a lot, when a stock RS6 is putting down more than the rated BHP to the wheels, something is up.

Meh there are a handful of cars that will routinely dyno more to the wheels than the factory claimed BHP. I don't know if the RS6 is one of them but it could be. I know the SRT4 will regularly dyno ~250 WHP and it's only rated at 230 factory.

It's not.

I bet :gay: if only they made it in a coupe i would overlook the FWD aspect.

95 mph is real fast for a 15.7 thats like in the low 14 high 13 range...
i drove a drag tuned toyota truck and i hit 14.9 1/4 only at 84 mph..but then again i was on slicks with a kick ass rear end

All these drag times coming up. I feel out of place. Never been to a dragstrip in my life. I think we have a 1/8th about 10 miles from here though.

dude we should get together you can fix my MS for EBC and we can run in nashville or something ;)

you idiots need to consider the WHP figure he gave is corrected and the time he gave is not. Bandi is something like 5200'

my 2000 altima ran a 15.7, it weighs more and has less whp. something's not right.

your HP numbers seem awfully high for 10psi with a greddy kit...upload your pics to tinypic.com

hmm so you are saying that altitude makes less hp. Damn and i thought FM was in the mountians to make more hp ;) Must be the purple zip ties and panosport 13 inch wheels :rofl:

you posted that shit before i finished reading the thread!

FM adds like a 20% correction.

fwiw, Tuscon is 2703'

...but Denver is not Tuscon....

I ran better than that with my JRSC. I was running 14.7-14.9's at bradenton. Although here and there I ran a 16. (SC belt slippage.) I think you can do much better....

hellloooooooo how many fucking times do I have to mention the altitude he ran at? FUCK.
if the population here has really become this dumb it's time to pack it in.

Bradenton is at sea level though.

damn phillip you beat me to it.

Yeah the altitude factored in to my times being slow, but it was mostly my reaction time, i raced my buddies wrx and he ran a 15.3, the people video taping me saw that i was pulling on him towards the last half, so i should be putting down better times. Mac did an excellent job tuning my car it runs much better, got a fast pass at the emissions station, and held together after racing. So im impressed. I also have to worry about a stock rear end and 146,000 miles on the engine. So granted i wasnt putting all my cards in. Plus mac went over my emanage install and figured out that the tuning shop in tucson did not install my emanage right. almost 16 wires, 9 were not connected, and they only connected the ignition timing wires correctly, i had to rewire it and move wires to the other harnes and then i was able to adjust fuel. In tucson there is only one tuner shop and its APEX motorsports on speedway, not the most freindly guys or helpful guys either.

Basic greddy kit, intercooler, 305's, 190hp walbro, emanage.

also bandimere is at 5,580 ft above sealevel, factor that in and everything is slower. I come back to tucson and squeal my tires just taking off normal until i get used to the altitude difference.

for what it's worth, your reaction time has nothing to do with your elapsed time. the time doesn't start ticking till you trip the beams out of the staging area, and stops when you trip the beams in the traps.

if you're new to drag racing, don't worry about your reaction times, they don't mean anything except who gets off the tree faster.

It's not your reaction time. You can have a 30 second reaction time and it won't factor into your 1/4 time as long as your car hasn't moved. It's your 60ft time you're thinking of. Which in your case is BULLSHIT. No offense. 2.7 seconds is really bad. Theoretically you will pickup three .3 seconds for every .1 second you take off your 60ft time. Obviously this may be a bit optimistic given your trap speed, however if your boost wasn't dropping then the trap might be 2-3mph higher, in that case I'd think mid 13s is possible even at altitude.

Im perfectly aware my 60ft time is crap, im pretty sure all my buddies that went with me gave me crap about it. I was having a tough time getting my clutch to slip enough, and i didnt want to just drop it, worried about my diff, either way every time i launched i ended up bogging it and taking off pretty gently.
