drag times v.s. motor types, b8-me, bp, b6t, bpt

okay I am confused..... post what you think (or know) what times to be expected form these swaps w/ no extra mods (except stripped interior)

b8-me

bp

b6t

bpt


I was doing math on 20hp increments providing our 64 hp motors run 18's
it seems pretty spot on with what each motor puts out...?
64=18's
84=17's
104=16's
124=15's
144=14's
164=13's
184=12's
204=11's
let me know what you think

^^ *note* those are fwhp. not crank

I'm interested in this as well. Maybe we should get a track times database up and running as a sticky and see what some of these guys run. Maybe FF.com has one

FF.com have a whole section for timeslips etc and this sorta discussion and a top10 fastest festivas. Weight differnce between the festiva and aspire is negligable once you get into bigger engine swaps. Seems like an alright approximate guide, considering a b6 dohc or a b6t swap puts mots festivas in the 15's category (or faster)

The main reason why there aren't any 11 second festivas around is because of traction, after a certain point the car gets too light and won't be any faster in the 1/4 mile.

there was a festy w/ an 11 sec 1/4 mile on ff. so it could be that 20 hp increments is a good judge upon what our cars will run in the 1/4. it is easy to get 20hp.
I mean, flyingmiata has a bp low compresion piston w/ up to a full mm bore aplication. put that in a bp+t or a bpt and BAM (depending on bore size), or on the bpt just slap on a bigger trim turbo and get a safe tune, I am shure you can get 20 easy. im shure you can get another 20hp out of the b6t w/ 2 more psi (a total of 6psi)

As someone who as run Festivas down the 1320 a LOT of times. I think your numbers with the 20hp are off. I had around 240hp in my red Festiva and the fastest time I ever recorded was 13.0 with an almost perfect reaction time, and that was with slicks on the front. That was with a B6t with a bigger turbo running 17 pounds of boost. As was stated before, Its VERY had to keep a little car that fast on the ground.

Don't forget that as the speed increases so does the wind drag, rolling resistance, etc.... and it's not proportional!!

Look at the applets for power and acceleration.

Here is a site for the HP required for an electric vehicle. HP is different between electric and gas ( http://en.wikipedia.org/wiki/Horsepower#Brake_horsepower), but it gives you an idea of how the power requirments are not linear.

"#5 CWS Tuning

13.2

From what I can remember, Cam had:

- Toyota CT26 Turbo
- SDS Additional Injector Controller
- BOV of some sort
- 323GT intercooler (not too sure on this one)
- Modified Miata intake manifold
- Festiva transmission
- ACT 4-puck Suzuki clutch
- I think he was making something around 196whp, but I could have got the numbers mixed up, because I'm also thinking that number was 169whp."

stock swap no mods is said that a b6t festy can run 14's the aspire weighs more so high 14's can be expected with a b6t stock swap

from csw site
"The B6T swap into the Festiva is in my opinion the very best bang for the buck in any car. Period! For under $2500.00 you can have a legitimate, daily driven, low 14 second street car and still get close to 40mpg!"

gade you also said you have a high elavation, tracks can be a bit slick too. I want to come up with a grid so I will take your time and come up with a grid on hp v.s. 1/4

oh my bad on the 11 sec festy it was a 12.1 ish


yea there are variables I wasn't thinking a straight line graph was realistic there is deff an equation though that would result in an upward curve were the more hp you have the less you have for a 1/4 mile time. (once reached past the eqilibrium point.

I think the 20hp incramens aren't too far off though, to a point. like we all stated before traction is an issue with the grid I have now it isnt bad, or off the b6t runs stock at like 132hp that puts it between the the 124 and the 144 hp rang and with that saidit puts it into the 15-14 second range which seems to be a common time for stock b6t swaps into festys (aspires weigh more but would still be in around this range) so lets say that past 144 is where the curve actually starts to get steeper. the bpt with a few mods runs 12's and 13's (180-220 in a festy) I think for where I live a 240 hp is past the equilibriumpoint. Traction is just too much of a nuisance at that much hp to result in a positive gain in the 1320 times did you try to kick it down a notch to see what you would run. again I am not neglecting your input I just need to know a few things. Gade you said you run your festy/aspire alot what did you get with your stock 4 dr or do you drag the 3 ( or am I being silly do you even have a 3 dr??) let me know what the stock time you got was
lets keep the info coming

to even further back up my 20 hp increments. on ff.com mextiva's ran a 12.7ish w/ 210hp. 6 more hp than my increment estimation, but then again the curve factor.
this is mextiva's 210hp monster
mextiva 12 seconds

Do I have a 3 door? Really? Of course I do! I actually no longer have the foor door.

I have NEVER run an Aspire down the strip. I have run all of my festivas though. My first festiva stock 4-speed ran 19.2, and my third one ran 18.3

But boy the crowds LOVE a festiva on the track

The 20hp is a good estimate for the lower ends of times.

Once you get to the 14sec passes alot of theorys that work for lower speeds and times go out the window. You get increased drag coefficents, things like ambient temperature, humidity, ground temperature, dew point, tyre pressure, altitude of ground. All these things start to have a bigger effect on your times as you get faster. Its very hard for such a light car to get traction and have enough down force to keep enough tyre contact with the strip to pull 11sec passes.

Fiest time i went out i ran a 19.1 with my full boot install (200kg). And im slowly getting faster.

There are to many factors involved in drag racing to be able to estimate accurate horsepower to time ratios. Also remmeber that accelaertion isnt a constant valve when drag racing.

dvdreith is there anything in particualr that you want to aim for. like are you trying to figure out what swap will get you the times you want?

yea which swap and which motor reacts better to modification. I wanted to make a grid based upon each motor, keeping in mind that it is about stock weight w/driver (2004lbs)
the 20 hp per second gain was based on whp. the figures that I have for each motor is all in the crank so I know that if a stock aspire runs about a 18-19'second pass, an average of 20 gain to the wheels would on average bring it to a full second faster per pass, based on the reserch I did on ff (keeping in mind that the aspire weighs a bit more) each of the swaps (with the exception of the b8-me) and a few simple mods like cone filter and axelback exhaust, the festys ran about what my grid showed for whp. so the whp 20 gain/ per second faster up until the low 13 is actually remarkeably close. one of the reasons I decided to do the graph with whp is to sort of create a buffer zone for all the inconsistencies that drag racing has. I will finish up the graph and post it in a few days

so moral of the story, if your goal is close to 300hp you might as well figure the costs of awd to really enjoy it.

Hells Yeah!
