Finally ran some decent times today.
 

No EMS, running on Azenis, and 10psi with a T3/T4E

60' - 2.078
1/8mi - 8.627@83.62mph
1/4mi - 13.279@106.82mph

There arent any other local turbo miatas, so I really have no one to compare times with. Does this seem like a decent time for 10psi?

I think any miata running low 13s is impressive.

Hopefully I can make some improvement next time, I have a set of shaved Toyo RA1s that i've been wanting to try at the track. Have any of you ever run a 2 step or something for launch control?

dude thats not bad at all, i ran a 14 at 12-13psi and the same tires. What is your suspension mods, rear camber, and launch rpm like? I am asking because while I ran a 14, my trap speed was 102mph and looking at your time that should put me at a 13.5 or so with better driving.

btw, i think i should mention that I had reaction times of about a second because it was my first time and due to a friends faulty explanation of how bracket racing works I focused on my launch instead of taking off immediately. I was under the impression that the winner was the person who had an ET closest to their dial in without busting and ended up loosing by .2 seconds to a bmw who was quite a bit slower than me just because I left late. Found out later its the person crossing the line first who wins. Dont think that it played into my ET though because i think the timer begins when my front wheels lift off of the weights.

not bad, I think you are probably giving up power somewhere though. a standalone is in order.

Picking up 23mph between the 1/8 and 1/4, not bad. The traps are there for 12s if you can get your 60' time down to 1.7-1.8.

What is the trim of your turbo and what are you doing for fuel?

very respectable indeed.

nice nice

Im running JIC Magic FLT-A2s, 500ft.lb/400ft.lb, front damper at half, forgot what the rear was at but it felt good so I left it. Im running 2.5* of rear camber. I tried launching at 3k, but the track was so sticky (120* track temp), it bogged really bad and yielded a 14 flat, so I upped it to 4k or 4200 and started hitting the 13s.

Im pulling max timing on my bipes (timing set to 18* before retard IIRC), havent really messed with it. Im playing it safe on timing untill I get EMS. Im selling both of my RX7s and the sound system out of one of them to fund MSPnP, so HOPEFULLY I will be able to order that soon..

T3/T4E, 50t .48 .60

I have a DIY dual feed (leaking BAD, a FM is on its way.. For once I caved and bought something non DIY :o ), Walbro 190HP, and a BEGi FMU. Stock injectors :/

wow stock injectors...how much fuel pressure?

walboro 190 so i would say 95-105 or so.

nice times! wish I could get my 60ft down around 2.0.....

Very nice man, can't wait to see what she will do with the proper tuning.

Im running 65 or 70psi fuel @ 0psi right now, any more and the fitting on the diy rail starts leaking - the tap was slightly crooked so it ended up not sealing properly.. I guess JB weld doesnt fix everything after all lol. Once the new rail arrives I can finally up the pressure.


Whats your average 60ft? The track was insanely sticky that day, I usually average like a 2.16-2.20. I wish I ran a cam in the car so I could see what the heck I did on that run.

Thanks man, im really anxious to get MS.. Someone buy my RX7 to fund it! haha

my 60ft's range from 3.4 to 2.7..... the car just bogs, or roasts the tires....

What tires are you running?

cheap 205's, on 17" wheels. My trap times are all between 107 and 108

Oh, gotcha. Do you put alittle heat in them before the run?

nah, open diff doesn't help with that

Apex. I tried to PM you about your rx7's and some more information and pictures but your pm inbox is full

Sorry man! I'll empty it right now.

Actually just shoot me an email at mdecesaro@gmail.com , im rarely home and for some reason I have a hard time accessing this forum on my phone.

I think the Azenis are awful for drag racing. I tried it a couple of years ago and had problems, it was either spin or hop no in between. my best 60 was 2.2. my best time was a 13.9 at 99mph, that was a 1.6L with a FMII at 12psi. I think the sidewall on the Azenis is too stiff.

Of course its too stiff, its practically an autoX tire. I consistantly run 2.0 60fts on them though, I think if I learned to slip the clutch a little more I could get it down to 1.9 or maby even 1.8 if I really hooked up and all the planets alligned just right. On the run I ended up breaking my diff on, it finally hooked up like I had allways wished it would.. Im going to try lower pressures next time, all the runs I have ever made on the Azenis were at 32 or 34psi. Going to try 26 or 28 next time. Next year I want to get some drag radials though, then i'll really start breaking shit...

You're obviously managing to do better with them than I could. Heck you did better with them than I did on my kumho's. I only made 2 passes , probaly could have mustered a 2.0 with a few more attempts but shoulda woulda coulda never accomplished anything. I tried lowering the pressures on the falkens and if I remember right it made it worse. just watch out for wheel hop.
I forgot to add congrats in my previous post that's a very good time.

Thanks man, this may sound stupid and I may be completely wrong, but I think the 60ft times may also have something to do with the turbo size (in addition to the azenis). I went with the T3/T04E 50t .48/.60 trying to have a turbo that was alittle laggy, yet not so bad that I was a dyno queen.. Of course I picked the size before I learned anything about compressor maps so it was just a guess pretty much lol, but I think my 60ft times have alot to do with the fact that it takes quite a few feet off the line before I hit boost, so by the time I recover traction from the initial launch, it starts hitting full boost. Please someone tell me if this is a stupid theory, because I may very well be just imagining this lol.

Sounds logical to me.

Tried to snag a new fastest time this weekend, came close but no cigar :/

It was my first time back since I blew my Torsen so I kept pussy footing my launch.

got smoked by the 350?

it's ok dude, my run last week resulted in an 18.5 after I blew an intercooler coupling off and let out of it

Haha no, I ran a 13.3 that run, the 350 ran a 15.7. If you look closely you see that I get ahead of him then manage to stay out of the cameras view the whole race(blocked by the big ass truck), hence the shot of me first on the return road. Ill have to post up the second cam angle.

WOW...thats pretty damn fast...u can kick a lot of street legal cars ass on the street...i have a friend with a FMII miata running 15psi of boost and just barely making high 13s... best time was 13.8

Our local track is pretty nice, it hooks up goood.

nice times.... i ran a 9.0 on the 1/8th with my secondary fuel line leaking and i was running lean and fuel cutting on 9 PSI, i got it fix and i hope to go back and run a low 8 =]
