So you cross the traps in 5th? Any idea what RPM?

Probably low since he said some people coasted through the trap in neutral.
I assume that shift has to be kind of like the 2-3 in the 5spds.

Did you ever make any runs in the car prior to swapping the motor and diff mounts? Do you think they are helping you leave the line a bit smoother and also without worrying so much as to breaking the rear end?

I really want new gears now!

Sorry to threadjack Patrick but I have to ask APex; who's "pagsam486" on your Timeslip database and do you know what his setup is? I find that time incredible on a 238 whp Miata. I imagine he's got some nitrous.

Could you add me to the database? :)

paul let me know when you're going to atco, i've been waiting on a buddy with a chevelle forever to finish his car so we could go down together, and now he's totalled his tow vehicle. anyway i'm getting impatient

No clue, no posts, but the time seems legit enough. Wish they would speak up and post their specs! I also saw the Evo in 2nd that shouldn't be on the MIATA TURBO time slip board.. Oh well, what can you do.

Sorry but you have to add yourself, go into User CP / Edit Profile, towards the bottom of the page is vehicle info.

Rafa: It's a 6 speed with a 3.63 rear end.

18psi:
The bottom end is stock.
Begi S4 with GT2860Rs.
3 inch exhaust turbo to tip.
Xede custom tuned by me :giggle:
Apexi AVC-R boost controller
Mazda comp motor mounts
Poly diff mounts.

257 hp 210 ft/lbs

I have no idea what the car weighs. It's heavy though.

very nice man.....very nice

2nd Jay's question.

Did you run it prior to the motor and diff mounts? If so, what did they do for you?

Sorry, I completely missed that question.

This was by first time at the track with this car, so I have nothing to compare it to. I will say that on the street, the diff mounts made the violent wheel hop much more bearable. Rather than hop, the wheels will spin and they can be reigned back in with the throttle.

in for rear end carnage.

:giggle:

It's going to be a while. Open track is next on the to do list.

Wow, those #s are insane! Great job... not only does the car look good... it runs well too!

So BTW, when did u go with the Xede?

Cheers,
Prospero

Ran the quarter for the 1st time in my life last night. RT's? We won't talk about those. I know, launch on the last yellow. Maybe I've gotta leave on the 2nd one.

Anyway, my 60' times, like many here, were the suck. 2.25 was about my best. Most were in the 2.4 range. Wheel hopping SOB.

What can you tell us about making these cars launch that well! We need to know!

Thank you. I've had the Xede in there since the day before I went turbo. Sometime in January when we got a warm snap if I recall correctly.

First, don't worry about the reaction unless you're running bracket or head's up. Sit there until you have everything set for your launch. That's the single most beneficial thing you can do to get a good ET.

The track had a reaction time competition that day. $50 to the first .500. I nailed a .504 and a .502 but just couldn't get it done.

At least it wasn't pro tree :giggle:

I did a TON of +2second 60 foots that day, so don't sweat it.

Here are some things that helped:

Do a dry hop after the water box to get the feel of the clutch

Leaving off idle resulted in a 1.9 60ft, but the MPH suffered.

We aired down the tires to 20 psi. This helped out with the wheel hop tremendously and definitely gave the car more traction.

Too much RPM out of the gate was the biggest killer. I played around with leaving at 3,200 and it was just too much. The wheels would spin and the run went to crap.

2,500 rpm seems to be the magic number for this car.
Pre-stage, hold the car rpm at 2,500, slip the clutch a tad to stage, quickly feather the clutch and feed in the throttle, right to the point where it felt like it was going to spin.

I'm kind of curious what 60 the slicks would have yielded. I don't think a sub 1.4 is out of the question.

I hope this helps a little.

nice time

for the hp and boost very good

Pschmidt,

Followed some advice. Thanks! Forget the RT's and concentrate on launch. My best was also at fairly low RPM's. Slipped the clutch plenty to keep from bogging. Amazing the difference in what a 2.0+ feels like vs. a 2.25. You definetly know when you get it right.

Hey, you still need to go into your cpanel and add your info. Go to details and scroll down. There are fill in blanks for 1/4, 1/8, times, mph, etc.
