I just ran my car using my friends G-tech (We have a fellow 3rd gen on the board running 8psi /250hp wanted to run a test, those #s seemed kind of low) I set boost @8.5 psi (couldn’t get right on) plug the g-tech in jumped in and went out for a test drive. I headed to the highway, pulled over to the break down lane until I was clear of traffic. Set the G-tech @3200lbs and punched it. I had run 13.3 @109 and the g-tech displayed 314hp. Pulled over preparing to make another run and I noticed the engine was over heating, the gauge skyrocketed to H, I turned the heat on full blast, and wasn’t getting any heat! Open the hood and discovered coolant flowing out the water pump. Its –2deg outside, I have no heat but the car is overheating (go figure)
Moral of the story: a VE should put out more than 250hp @8psi and never test your car when its under 0 degs

 

Do you have stock injectors?

 

what!?!?!? always test the VE when it is below 0* outside... always! heheheheh

it was 18* out here the day I put my freshly ported intake manifold back on, first gear had absolutely no traction at all.... sadly it wasn't so much because of the porting

 

man...that cold air can do cool that charged air going through your IC pretty good eh ? that could have been a factor for those numbers. i want a VE

 

I'd just like to say that your car rocks man.

On my friends Gtech I ran a 15.3 @ 96 or so. W00t for me.

 

nice numbers man

 

although the HP from a GTECH isnt going to be quite as accurate im sure your easlily putting down within 25 hp of that especially since you ran a 13.3

just curouis but what is the reason that you cant make it to a dyno


and yes -2 degree + VE + 8psi = MADDDDDDDD HP

plus i bet your car wieghts more like 3300lbs with you in it especially with all that turbo crap because mine wieghs EXACTLY 3140lb and i wiegh 160lb so depending on your wieth and the extra pipeing and such your car could wiegh more like 3400lbs which is going to give you an even better HP reading on a gtech

none the less nice numbers because the gtech is very acurate in the 1/4 mile

 

If you underrate the numbers on the gtech it makes the gtech give you underrated numbers which is good, makes the numbers more accurate.

 

true the other thing is

does the gtech estimate the numbers for Wheel HP or Flywheel HP
if FHP the numbers will be in the 275 WHP range but who knows the only real way is to step onto a dyno

 

extreme cold + improper coolant mix = frozen radiator = exploding water pump.

doh!

 

whats the temp that will cause lets say 75% water and 25% antifreeze to freeze anyone know

 

pretty sure gtech goes for wheel because it is an accelerometer (spelling? lol). Plus it has no way to know the specific drivetrain losses.

 

good thing houston is still in the mid 50s and 60s during the day

 

that and my car is up on jackstands with the tranny in the garage

 

sounds like I lost that bet. well atleast I dont get a swift kick in the nuts.

 

That is awesome. G-Tech can be VERY accurate if it is dialed in right. If you are laying down those numbers that is great! a 13.3 is great! I really hope you are laying them down, I would like to know more about your setup, the style piping it is. Can you PM me? I sent you an email about a week ago and never heard back, heh...I guess cause the email system is down

 

Don- he had mandrels from JC Whitney. They cost him a bunch to ship because he was in Hawaii.
He had a chop saw on his driveway.

I can remember things

 

what captain obvious said

 

you'd have to know the freezing temp for antifreeze to figure that. Can't recall my chemistry too well, but you *might* be able to use vol. expansivity to calculate that using some other variables...i think...heck what do i know? i'm a cs major.

 

-84 Degrees Fahrenheit

 

are you serious or is that just a guess

 

Well, its a guess based on the purity of your system, but its accurate with in a few degrees.

 

so 4signs were you running 100% water

 

Good run bro. Whats the progress on the exhaust setup? Looks like yours and my car are having a tough time in this cold huh?

 

You can approximate it with the freezing point depression equation: (change in freezing temp) = Kf*m2, where Kf is the cryoscopic constant (must look it up for antifreeze), and m2 is the molality of the solution (moles of antifree / kg of water). This equation is derived from the difference in solvent activities, which always befuddled me in thermo.

 

AAAaaAAaAAAaaaaaAAaaaHhhhhHHhhhh no more math please!!!!!!

 

4signs, when do i get to run you? it would be my pleasure to get smoked by a boosted VE

 

I have my doubts about the the g-tech. I rather see what it can do on a dynapack it yields honest numbers compared to a dyno jet. But you are obviously running more than stock. Good job on the turbo kit

 

What there is a turbo on a VE!

 

Come here, You'll get smoked by a non boosted VE

more than one

 

3 white VEs post in a row

 

I think its time for a white ve club

 

i cant get over how nice your car looks !! what body kit is on there ??

 

I been really busy and dont have the time to really tune the car(bring it to the dyno) I still havent had the time to even finished the exhaust(I have 3inch down pipe heading out into the pass wheel well)

 

yes, until spring

 

just a modified stillen front lip to fit around the IC

 

no I replaced my water pump when I was in Hawaii, I only put 1 gal of anti-freeze,some water wetter and the rest water. I forgot to adj. for the change in climate when I moved over here It should of hit me when I heard the belts squeal

 

white VE 5 speed club?
