Yea my fd makes 310rwhp and 290tq on stock twins, stock motor and stock fuel system but an m2 ecu. I want to do a 160mph on the highway or top speed run. first of all what is the top speed i could go right now with my fd and after i do the run IF I do it how long should i let it cool down. thanxs

Where the heck are you gonna do 160 in Fairfax?! Let me know so i can be sure to NOT be on that road.

You really won't know unless you have an aftermarket temp gauge (or you linearize the stock one). How else can you tell how hot the car is?

Just don't stop the car right after a hard run, drive it without boosting for a little while so air can move into the engine bay and cool things down.

177 mph with 360 flywheel hp

This assumes stock gears, wheels and tires.

haha if i do do it it would be at 12 at nite on 1-95 or probably in maryland or from washington dc all the way down to alexandria or springfield

Shabib67

mahjik thanxs for the advice but the other thing is after i do what you told me to do how long should i let it idle for

HeatTreated

I would get up to atleast 90mph and get out of boost for a minute.. Then punch it and take it up. Do not roll onto the highway and punch it, you will be in boost a long time and that could be bad with the power your pushing.

If you have driven it around for say 10-15 (or more) minutes off boost, then there is no reason to let it idle.

Letting it idle to cool down is a bad thing. There is no air moving into the car while it's idling, so all it's really doing it just generating heat.

THIS IS NOT A GOOD IDEA....

Shabib67

and why would that be

Mahjik,

What exactly is "Linearize your temp gauge"? How do you do that? Will that make it accurate?

Search for "linearize guage".

Let's see-------in terms of likely problems and in order of least problematic to worst case scenario (every one of these is equally likely at speeds above 100mph):

1. speeding ticket
2. reckless driving ticket
3. reckless endangerment ticket
4. hydroplaning on unexpected wet (water, oil, coolant, blood etc) roadway (no further complications)
5. unexpected animal or debris in roadway (no further complications)
6. unexpected response from your suspension system (no further complications)
7. momentary loss of control based on item 4-6 (no other complications other than the need to change your undergarments).
8. engine overheats (no additional complications and you slow down to cool the engine)
9. engine blows (no additional complications and you coast to a safe stop)
10. engine blows and seizes (best case scenario no loss of control [e.g you manage to disconnect the drive train via clutch and coast to a safe stop).).
11. catastophic failures in engine and/or drivetrain causing you to spinout and wreck the car.
12. catastophic failures to your steering gear.
13. tire blow out (associated with wear or inappropriate speed rating or tread design).
14. Your car being damaged as a result of 4-13
15. You being injured as a result of #4-14
16. You being killed as a result of #4-15
17. Someone else's car being damaged as a result of your stunt.
18. Someone else being injured as a result of your stunt
19. Someone else being killed as a result of your stunt.


Enough reasons? or shall I get more detailed?????

Some people sure have ALOT of time on thier hands

STOCK and FD will go 165+ on 255fwhp, with 350fwhp it should push 180+ BUT I would not run any FD over 130 w/o an R-1 chin spoiler or some other PROVEN EFFECTIVE AntiLift devices on the front end, and A wing or spoiler on the rear - The Racing Beat LSR car w/o a rear spoiler produced enough lift at 220mph to pick the rear wheels off the ground causing the car to spin and get Airborne then flip a couple times - OUCH!
Do a search on TREV & Accident - His car got FATALY airborne at 150+

Hyperite

Impossible, unless it was instantaneously produced by something other than the car. Think about it. You're going faster and faster, creating more lift. When you get to the point that would lift them off the ground, you no longer have any forward acceleration, and they would drop back down. Now theoretically you could get to a point where there was enough lift that the car "weighed nothing", but not enough to fly.

Does this help paint the picture???

Watch the video again, (do a search on Google for Racing Beat RX-7 Crash) the car definitely has an R1 rear spoiler, can't tell about the front one though. It looks to me (I'm no expert on automotive aerodynamics, but I am a pilot so I'm somewhat familiar with the principles) like the rear end is making so much downforce on the passenger side that it pushes that side down so far it actually lifts the opposite (front driver) side up and as soon as that happens the whole thing takes off and spins.

wanna know why its not a good idea? go here

Sometimes theory and reality are not the same. Theoretically the car shouldn't have crashed. Obviously it did.

maxpesce

Let me clarify my previous statement - the Racing Beat car produced enough lift to cause loss of TRACTION at the rear and a resultant LOSS of DIRECTIONAL stability. This caused the car to develop a large yaw angle (basically traveling sideways) and subsequently lifting into an Airborne flip. it did not actually lift the rear wheels off the ground while traveling in a straight line.

jesus christ juancm5483 i just might not do it now omg thats the sickest thing ive ever seen. but ive seen a stock audi s4 pull 160 on the highway without it fliping over or whatever so i dont understand why the fd would flip over or lose control and ****

Nobody is saying that it definitely will happen. There are examples where it has happened, but not all situations were analyzed as to why...

However, are you willing to take the chance?

Doing things like that on public roads not only puts your life at risk, but others using the roads as well. If you want to open up your car and see what it can do, check the SCCA for events near you: http://www.scca.org/

Shabib67

i guess your right mahjik but the thing is i wouldnt do it when others are around but thats impossible to say that no one would be around. the thing is like there are some parts in VA where its like arizona long straight roads that are wide and no one around so i just thought i could do it there

jeff48

Shabib67

Maybe no-one else is going to be around, but are you sure noTHING else is going to be around (debris, animals, slick spots etc).

When is the last time you had your car tech checked by a race steward (my guess----never).

Why are you so hell bent on doing this thing the wrong way when there are so many possibilities for doing it right?
