Learning to make fast go fast!

I guess I want to race this GTO too.

Forgot to multi quote. LOL


I made a trans tune for my 4r70w that shifts 1st and 2nd really fast and wont down shift to 2nd and with my loose convertor, I can make a pull from 3700 to 6500 in third that is only at 105-110 mph. If I go though the gears that rpm is closer to 140-145. Not to mention I have a ton of BMR suspension under the car making it hook pretty good. 2-3 pulls are hard though as it spins some if there is not enough heat in the tire.

What tires are you running during these pulls? I have strange 10 way adj struts fully loose up front and strange 10 way shocks in the rear 5300RA CJ springs all around and lots of BMR shit on NT05R's, my shit breaks loose so easy it ain't even funny! I never tried to heat my tires though. Oh well

MT et streets 325/50/15 at 25psi on the street with Dspec shocks set loose in the front and firm in the rear with Eibach pro kit springs and BMR everything else. I get it rolling about 60 in third and nail it. I sm on asphalt roads. I have his

So, right after I posted the above, I went out and logged for Manuel. I tried a 2-3 pull from 70 mph and boiled the tires so fast that the rpms shot to 7700! I then flipped the switch that I have setup on my Baummanator TCS to change the trans tune to the 2nd file that I use for pulls and dynos and was able to make a pull from 3500-6800 in third.

Like I told Manuel, I never thought I would ever say this but, the car is fast enough!

We are at about 11.5 A/F on E85 and 19* timing and hit 21.7 psi on the last pull with a 12.0:1 motor.

Now I just need to do the drivability stuff tomorrow and check into a noise or groan from the rear drag brakes.

Sounds perfect!

Billy did you shit yourself?

No?

Car isnt fast enough!!!

Yes, just a little... and the car is fast as I will need for a while.

That sucker did break loose, LOL!!!

Am I guessing correctly that the IAT wasn't during full boost after the sensor stabalized?

Tuning is going to be interesting this spring with Lito on my car. One advantage is it's direct drive so there is no converter beating the tires up. But I'm geared really tall. Top of 3rd is 140ish?

That is actual, here is the 3rd gear pull on the same log a few seconds later. Only 50* here today with cold winds.

If the vehicle speed data is any good (don't know if tire size we use is correct), you went 66-112MPH in 3 seconds.

28" tire and 3:73 gear.

I can't tell which line is the IAT?

Perfect!

For your mental health, you better not, lol.

What-Ever!!!! LOL!!!

I'm curious if you think that is a "stabilized" reading.

Perfect!

If its not checked there will not be a line. The temp in the colum line is the current temp at the point I have selected with the vertical red line. Everything you see on the left is real time with the vertical line on the right.

Was it that long? IDK, I was just holding on! No, wait, I just counted to three, it felt right! LOL

Duh, I skipped right over the obvious. I really should spend less time doing this on my phone.

Do you and Lito think that after 3 seconds it was reading the actual IAT?

Betcha is was nice to whack that sucker WOT after all the trouble huh?

Mostly, it was 78F at the beginning and by the end of the run it was on 82F, max read on the whole log is 90F.

That's pretty impressive.

I think I've noticed that A2A and A2W behaves differently depending on the outside temp. My HE discharge temps drop as ambient does, till a point. Then it doesn't matter how low ambient is, they will barely budge. It doesn't matter if it's 30deg or 70deg out. My HE discharge will be the same (within a few deg). I'm guessing a A2A is going to scale with ambient better?
