I definetly was lighter than just 300lbs off. remember its not a daily driver. OK lets see BR exhaust,no balancing shafts, no sun roof,rpf 1's with hoosie drs take about 40lbs off, no interior except seat and dash which is totally intact, I removed close to 20lbs in sound deadening, No AC (close to 40lbs), no oil cooler, small radiator, no undertray, all braces removed, lighter than stock carbon fiber hood, nothing in the trunck at all, crash beams rear and front removed (no need to comment). I could go thru all the odds and ends but im not gonna. Basically I searched the car for anything pointless for a daily driver and removed it. The car still has power steering, heat, power windows, Next up cutting up the back doors and pulling out the beams. My brother runs a bodyshop so this wont be an issue. Ill be looking closely to shave another 50lbs off for race weight all while reinstalling my front door panels. I plan on running 9's or close to it this year.

 

You see the irony in that statement right?!

 

yeah I know. Ive thought about putting the front beam back but it doesnt exist anymore.

 

This is my first time seeing this thread. Should elevation be a factor input as well?

 

could be. although I hear id get a better time at ATCO NJ. i dunno

 

elevation can play a factor. Our local track is at just under 4000ft. so really lets say 4kft. The tunes we do are at a spot that is 5000ft. We see an average of .3 off out ets between here and the next closest track in Sacramento (sea level roughly). We also see a trap increase of 3 mph average.

 

12.09 @ 114mph 386awhp 370awtq uncorrected
pls add

 

evo a mula | dyno dynamics | 504awh | 11.0@ 127mph | 3550 with driver

 

From the data provided from this thread, by using statistical data analysis, you can get a rough estimate of your expected 1/4 mile times and trap speeds if you know your HP and weight of your Evo IX.

Trend line analysis using the data provided EvoM members gave a better coefficient of determination, R2, than ET & MPH formulas and calculators I found online (SEE ATTACHED Excel zip file in next post).

 

Added Excel file to estimate ET & Trap speed based on dyno awhp (includes graphs, calculator, and comparison with online ET, MPH, and HP formulas)

 

Any feedback?

Thanks,

Jay

 

521 whp STM dyno, 10.28@137.... i think a nine might be in order this year

 

Do you have a weight? or estimate? I'm guessing almost 2900 lbs, right?

Thanks!

ENTER HP = 521
ENTER WEIGHT = 2900
POWER TO WEIGHT RATIO (HP/lbs) = 0.179655172

Est Trap Speed = 42.971ln(Power-to-Weight Ratio) + 211.65 = 137.9 mph
Est 1/4 Time = 62.213*x^2-41.108*x+15.697 = 10.32 sec

Those are really great numbers for a full weight car. Do you think your actual dyno numbers were lower than average? Most full weight Evo's show about 600-620 awhp on the "average" dyno to match your ET and MPH. Congrats... Impressive!

 

full weight nothing taken out for the track full tank of gas and my 215 lb of fat ***

 

Nice write up.
Should you add turbo and what size motor?
