My minivan goes 14.97 on 14 psi first time down the track!

I had a 2.3 60' time, i tried to stall it up harder to launch the second run but spun so this vid was my bes ot the night. Yes my sig says a best of 14.8 but that was on 19 psi and this was on 14 so i was pretty excited!

edit: i call this the first run because it is the first run on the new engine and trans rebuild.

Awesome but I'll ask again, SETUP??????? :eyebrows:

FYI, put it in your sig so we all know, :nod:

Do they play that gay music all night? :(

[2.216VTurbo]

Nice kill! I take it the elder Mr Lindsey (also know as Dad:D) had his hands on your build:) Say hey to him for me, never see him here:(

[Ubmbass]

I know why you spin so badly, it's those miniature version of slicks you are running. Get some bigger slicks and get em hot and you'll hook

CHeck out my Sig! :), any more questions?
and sadly yes they have the local rap station entertain the crowd. Luckily you can't hear it much from the staging lanes

Yes he helped with the engine rebuild, and he taught me all i know on rebuilds, but most the upgrades. The biggest help was tuning the cal which i did myself.
Plus he messes with his own van Look we have twins :p

I will tell him HI for you, he is not much of a forum guy for some reason :(

I know i have a set of 26x8.5 M/Ts i was just worried about the gear ratio. But if it will let me leave at full boost it shouldn't matter i guess.

[Ubmbass]

I ran 26's in my van and it worked just fine...

[RoadWarrior222]

I ran 26's in my van
Was that the '84 carb 2.2? :D

[GLHNSLHT2]

nice times.

LOL ya.. it was fast..

About time, :nod:

I run 26's but with my loose converter, they work great, so for you, I would recommend 24.5's or you'll barely use 3rd.

How much does it weigh?

[1BADVAN]

I would prefer 24" slicks too but i got 26" for $150
IDK what it weighs i would guess a bit over 3000 it has all the trim panels out in the back but still has carpet and a radio.
i do still use it as a family hauler here and there

[BIG PSI]

I would like to know the density altitude when you ran.
Can you scan your time slip and post ?


BTW--WTG !!

That's why I run 26's, got nearly brand new ones for $200 a few years ago, couldn't pass on the deal. With a stockish converter, I barely used 3rd, now with the loose one, I can actually use it, lol.

Time slip in post #1
Altitude is 4400'
Density IDK?? All i know is every time i hear the corrected altitude at that track it is like 7000' we have very crappy air quality up here.

Thanks to all for the compliments!

[turbovanman²]

BTW, TSMEC or TSBEC? :eyebrows:

[Ubmbass]

It was 7750 density alt correction that night.. just got to check on the ole 1320go.com lol

[Vigo]

Congrats on the runs! There are some people here who cant run 14s even with 20 psi at low altitude...

Looking forward to running my own van soon. Im waiting for slicks :)

[RoadWarrior222]

edit: N/M was thinking bars and writing PSI

[1BADVAN]

BTW, TSMEC or TSBEC? :eyebrows:
it is a SMEC the previous owner swapped it to smec

[turbovanman²]

Interesting.

Show him they way, my friend.

You LOOSE 3% of your horse power for every 1,000 feet you are above sea level.
So at sea level and all other things the same your Mini would have run:

Hell the formula does NOT go that high.........

http://www.dragracing.de/archive/index.php/t-78.html?

At 5,500 feet it say you would run 13.95 @ 96.460

Great run...

Drag it out east next year, stay at my place for free, and let's go racing together.

Chuck

[Ubmbass]

His van should be a lot of fun if he puts some decent slicks on there. and gets that boost up.. I know from personal experience low 12's are possible up here

Can I come race with you guys over there? I want to hang out for free. lol

[1BADVAN]

I will have to try good slicks, and it would be fun to race at sea level! I know some guys say it doesn't make a difference on turbo cars that much, but i have gone to Vegas which is 2200' and the glhs i drove down sure had a lot more traction problems down there ;-)

It does NOT make as much difference with a turbo vehicle as it does with a normally aspirated motor.
But it DOES make a difference, trust me on that.

[RoadWarrior222]

A way to describe it is, with 14 PSI you're at about 2 bar, at sea level whereas N/A is one bar. Then when at a height where the N/A is only getting 3/4 bar, you also lose 1/4 bar, but it's only an 8th of your total power rather than a quarter... and the power loss will be proportionally less, the higher the boost is.... (Like at 29psi it's a twelfth)

[Vigo]

That is one way of looking at it, but generally speaking you are either going to be running boost control from a grainger valve or the map sensor, neither of which gets 'offset' by altitude, so as you go up in elevation the turbo will just spin faster and faster in the thinner air to hit the number the controller wants to see, which adds heat to the intake charge. So under normal circumstance you'd have the same boost, but more heat ( = less density) in the charge air.

[Ondonti]

Your self deprecating humor is the best!

This, and turbos will run out of airflow (reaching choke flow) at exactly the SAE HP correction factor for HP at your altitude. 17% less potential from any turbo up here. That only refers to the compressor side, not a setup where backpressure is the limit on your HP. In that case, you don't lose as much as the numbers might predict, but you will see more heat when you try to make up losses.
There is a good amount less wind resistance for a van at 4400 feet. Only thing really in your favor along with decreased backpressure.

lol, i havent even tried yet!

Never thought about that, interesting.

[RoadWarrior222]

So if you wanna hit mach 2 in it, pressurise the cabin and go to 60,000 ft or so....

[Ubmbass]

Never thought about that, interesting.

Don't listen to him, it's not true lol.. The difference is very minimal. still feels like you're trying to plow the air up top

[turbovanman²]

Of course you'd say that, lol.

well, ya haha
