We took the car out tonight but only got in 1 "semi" serious pass. The first pass the car got really loose so we upped the tire pressure and the 2nd pass I was able to stay into almost to the 1/8th mile mark. On that pass I left the line with only 8psi so tomorrow we're going to keep running the boost at the line higher until we lose traction. We've run it as high as 30psi on the transbrake but that would of course bust the tires free. It takes a little while to stage that big turbo so in the future we'll run a small shot of NOS to get it to stage quickly. Unfortunately it rained after that pass so we're going to try again tomorrow.

Here's a quick video of PIR today.

VBox Log. 1.3gs. Zero to Sixty in 2.2 seconds. Zero to Eighty in 3.1 secods. Lifted a little at 5.5 sec, Let off at 6.2 seconds :)



Here's the dyno graph right before the run. The auto and the "loose" converter makes the power "appear" quite a bit less than it would be with a manual transmission.

How is your trap speed 86 with a ten second 1/4? I trapped at 128 spinning half way down the track in my mustang in a 12.78 pass

^ It's because he let off at the 1/8 mile. If you go over 135mph or 9 sec you need an NHRA licence. He was already at 111mph in the 1/8 so he would have been over at the 1/4.

I saw the 1/8 mile time, just hard to believe he let off that soon and still ran a 10! Damn!

I was wondering the same thing, like WTF?! Engrained into my memory is a previous best of 14.69 @ 93.5mph in an old car, so I'm thinking what on earth was going on here.

There is no way I would think fast enough at the 1/8th mark to let off the gas so I wouldn't break 135mph.

Congrats, that's awesome!

Can't wait to see this thing run a full pass. It's going to be impressive.

What does the dash say when you start it? Can't make it out in the video? I programmed my Aim dash in my racecar to say "You are the Stig" when it starts up:lmao:

6.08 1/8 mi I would guess around 9.3 1/4 mile in that current configuration/launch. Car sounds good!

Here is a slip from Donovan's E30 with a similar 1/8 mile time. The traps will be lower with the auto trans.

I found the video to be interesting and informative...especially the 60' time...impressive! Thanks for posting. I kind of like the car the way it looks now. I know you have plans for a fancy paint job later....
Where is Fallon? She has to do this too.

Note: Chris isnt working on reaction time at all right now...just staging and license runs. Once he gets used to all the things needed to do to stage properly THEN he can work on RT.

You're trapping super fast. Nice work. Work harder and you'll break into the 90mph range.

Sounds awesome dude! Can't wait to see this thing running full out.
Thanks.

Wow, thats moving.. 10.65 @ 80 or so mph!
It felt so incredibly smooth. Like taking off in a jet.

Fallon wanted me to make sure it's safe before she drives it. So I got to take the first passes. :) I will have the RT's down to .01 or so once we run spray to get the converter on line.

Definitely a low 9 second car the way it sits. A few tweaks should get it to 8's. Reaction time needs a little work though
Ha ha. I agree 8's will be just a few tweaks away. I'm going to do my license passes tonight and we shall see where we end up.

Thanks Mike. We will try coming out of the hole a bit harder tonight and hopefully get a full pass.

I would agree! Should see some pretty fast times now that this is a purpose built drag car.
Plus It's running the old HPF Built motor out of the orange car. ha ha.

Thanks. :) It says "HPF Drag M3"

Very quick that's for sure...definitely in to see this beast go faster! An auto definitely puts the power down.
Thanks Kenton.

That's a really quick 60' time, can't wait to see this beast completely off the hook.
Thanks. I'll have onboard go pros next time.
