Took my "hybrid" to the dragstrip..best run was a 14 flat in the 1/4

Re: Took my "hybnd" to the dragstrip..best run was a 14 flat in the 1/4

i've abused my prius and i have raced it in parking lot solo racing. from what i've seen.. i seemed just fine to force charge.. gas and brake at the same time while in D.. it won't do anything in P.. and the even though it's a lexus it most likely won't brake loose under full brake and throttle due to the nature of HSD...

i figured a high rev is still the best way to launch.. but you'll still get slower times eventually due to heat built-up in the battery. so... rev up till it's nice and green.. wait for the car to shut off the ICE... 7 not 8 green... after the ICE shuts off, things should be " cool".. so rev up till it's full green.. ( it won't do it every time)... the car will want to drain the pack, so shut it off. It may not start up in EV mode...

instead of driving around, you can let it sit and have things try to cool after the force charge and before the force launch. btw... if the battery get toooo green.. the ICE simply won't turn on

 

For better launch, you really want to be running, in D or B,
and just finishing your force-charge at the line. To launch,
you're already holding the gas fairly far down with your other
foot firmly on the brake, and just releast the brake as you
floor it. You'll get all your MG power snapping your neck back
right there as the engine rapidly spools up the rest of the way
to come in and help.
.
It requires a little different thinking about how the hybrid
system works and where the delays are, but that 450 should kick
some serious butt -- it's a richboy's muscle stocker, no question.

Can you calll into a cold store on your way to the strip with a big ice box and buy some dry ice wrapped in news paper. Remove the trim over the battery pack and while force charging have a slab of dry ice on top to remove heat. Remove the dry ice or secure it under a blanket with ratchet tie downs during your runs.
You can also use dry ice to cool the inverter.

Even water ice will help but is messy.

 

How did you place over all? I'm thinking vdim still being active might still have had an "ill" effect on your drag racing. I found this video online where some races a gs 450h and a bmw 335i (i think) The gs seems to really hit its stride over 60 mph

 

1972 Chevy Chevelle

 

Actually is was likely a 68-70 Chevelle SS. Notice the dual headlights. It is a dead giveaway because the 1971-1972 Chevelle had single headlights. The side blinkers are also located low on the fender instead of high up closer to the headlights. Since I am not an expert and I cannot see the backseat window
968-69 came to a point, 70-72 the window was squared off towards the back) or the rear bumper (square tail lights vs. dual round ones, except 1970 model)I cannot be sure.

1970 Chevelle SS

 

It suddenly struck me to ask: what tire pressure were you running?

I had a 1967 Chevelle and I knew it was later than that, Thanks for correcting me!:mod:

 

Hopefully his pressures were low so that he can now air those tires up and reduce rolling resistance and get a better ET/MPH! High tire pressure will also help with rollout from the light meaning you will cut better lights and get moving quicker.

If you are looking to beat your last time try and choose a day that is:

1. Cold (cool air is more oxygen dense)
2. low humidity (less water, more oxygen)
3. High barometric pressure

These factors including base altitude affect your "effective" altitude (also called Density Altitude or DA) which in turn affects how well your car will perform. The lower the effective altitude (DA) the quicker/faster you will run at the track. So if you choose to run on a hot humid day then you can expect to run slower than if you chose to run at the same track but on a cold low humidity day. People generally don't break their records in the summer months. Fall is about the best time to go for record times.

In a nutshell think of it this way. On hot humid days with a high DA it can be like running your car at 4,000ft. elevation but on a cold low humidity day it can be like running your car at 3,000ft. BELOW sea level which is amazing for performance! The higher the elevation the less pressure and oxygen and your car needs lots of oxygen to make good power. That is why nitrous oxide (oxygen is the active ingredient) and turbo/superchargers work so well, they add a bunch more oxygen to your engine!

Here is a generic density altitude calculator so you can see how weather affects your effective altitude: Density Altitude Calculator - English

This weather site will allow you to look back in time to see what the weather conditions were for old track times so you can check what the DA was on that day. Scroll down to "History and Almanac"

No worries Jim. I'm jealous though, '67s are SWEET! I almost bought one but got a 1972 instead and it turned out to be a piece of junk. lol

 

I just want you to go back and wipe the smug looks off of the motor heads' faces when they see a hybrid beat them . How much time do you get between each heat/round?

 

Smuglex, why settle for a chincy 13 second goal, and synergy drive ... when you can have 11 seconds, and use NO GAS?!
ENJOY!

 

Great video- incredible car, unbelievable motorcycle. Thanks for sharing.

 

ooo I feel a chubby coming on, those chevelles are my favorite cars of all time.
My high school bio teacher was just out of college and had a 72 ss. I can't prove it but I think he might have violated a few statutes about underage girls.
My parents had a 68 chevelle concours estste wagon, with the wood on the side.
