So Thats Whats Been Going on........

[wishihadatalon]

Think of the car like the wing of an airplane: high pressure air under the car is being forced upward toward the low pressure area above the car, hence 'lift' is created.

CAN'T WAIT FOR IFO THIS WEEKEND!!!

I'm sorry but high velocity air flow under a car along a smooth surface (under belly tray) creates a low pressure zone thus creating down force, not lift. Aside from part of the hood and some of the roof, I wouldn't consider any part of the upper part of the car a low pressure area. So you are right, the body of a car is like an aeroplane but upside down and not right side up.

I see the benefit being less down force, which should make the car easier to move as it will be "lighter". Should make the car faster, but probably would give a few "oh shit" moments.


Are you guys making that power through the auto? If so, holy hell, that is amazing.

The testing was through a 5sp. AND for the record I was using a used act 2100 pressure plate and a unsprung 4 puck for all the pulis. The loss to the auto has typically been around 18%.

Still impressive/awesome. Good luck this weekend if the rain holds out.

I don't know about the all the scientific stuff but when I was going 150+ it felt like like car was floating . Pretty scary at the time.

How the he'll did a 2100 PP hold 600+ torque?

 

[shortydtp]

Did u guys log any efficency data like backpressure with the new setup?

No we didnt. I will though in the near future when I have more time

Tested the auto tonight, she's up boost for boost from last season 100 whp same converter NO n2o involved. Did break the 800 whp mark with way more power to spare all this still on Q16.

Haha, just what I was thinking. Guess puck discs are just that beast. I drove an unsprung 4 puck car one time, er uh, tried to drive it , car was a someone's dd too .

So my new tire and wheel combo just showed up. Nothing like a few days late for a race. Im gonna use a set of M/H this season 26 x 8.5x15 on a Weld Racing 15x8.3 wheel. I'm hoping this should help cure some of the launch issues and wheel spin to the 1/8th mile. Last weekends trip to the track, although impressive, was plagued with little things holding the car back from a solid pass. All the issues have been addressed and Im now ready to go back again in a couple of weekends. I have a strong feeling this next time around Im gonna get a visit from the track people telling me to slow it down. I will put some new pics of the tire wheel combo vs what was on it before.

Pretty sure the clutch was a used 2600lbs perssure plate with a new unsprung 4 puck. No way a 2100 would hold that power. When I drove the car on the dyno it felt like a 2600.

 

[okcpopeman]

On EvoM he said it was a 2900, regardless, impressive.

 

[eclipsed4seed99]

Apparently we must all be confused on some stupid ACT friggen clutch cover JESUS CHRIST!!!!!!

 

[LucasEnglish]

Well either way its was 2600lbs or bigger.

 

[eclipsed4seed99]

We just finished fabbing up the new radiator, new 15in FAL fan should help a bit better than the old 10in fan. more stuff should be in tomorrow for weight mods and getting the new tire wheel combo on. I'm still thinking next weekend for some more seat time.

 

[eclipsed4seed99]

Radiator and FAL fan with full shroud works perfect, should have done that years ago. Wheels and tires are all on, alittle one way or the other on the looks, the stance is awesome not sure the half polish half black is the look I wanted. More weight out last night too, steering column mod was good for another 25lbs. Clean up the harness a bit and I should have it back together tonight. PICS later today of new wheels. tell me what you think.

What size are those slick's 22in?

Yeah cause everyone that runs 1000+whp and mid 8s runs 22 in slicks.

They are-

15x8.3" Weld wheels
8.50-26-15 M&H drag slicks

 

[slowgsr]

The wheels are beautiful

 

[pantherballhp]

I was just looking at jegs the other day wandering what these would look like on a 1g Dsm. They're beautiful!

 

[eclipsed4seed99]

At first I wasn't to crazy about them, I'm a bit partial to the murdered out look, but they are growing on me. In the end they will most likely get powder coated flat black to match the car. I'm also very pleased on how the new steering column and wheel turned out, took out 32.3 lbs and put back only 7lbs, with having a removable wheel it's way more easy to get in and out.

 

[SBstar]

Looks pretty good, how much do those wheels weigh?

Picked up the Modified issue last night, was a little disapointed in the actual writing/story, but the car looks great!

that steering wheel is really nice.
