The setup has been on the car since 7/2007. Build thread link in sig.
Apexonyou is still my hero! https://www.miataturbo.net/attachmen...ine=1365956985 |
Damn that's good. Congrats man!
What tire/wheel combo were you running? Edit: Still on the 4.10? |

very solid run, trap speed is great too, 'grats man
|
Impressive. I have to ask: you mention in the first page of our build thread that you autox twice monthly plus daily driving and track duty. Has your entire eBay setup held up to that all along?
Will continue reading your build thread... |

Will continue reading your build thread... The car does no one thing great but is a blast to drive and has working A/C. I feel that I've spent the least amount of money to get reliable power yet be conservative enough to make a worn out engine put out decent power. I don't want to disclose what I think it puts out(flame suit out being repaired) but the weight of the car going down the track was 2528lbs and the trap speed was 118.39mph. Plug that into a calculator and it returns true whp per pure physics. |
You and Apexonyou. Were basically the inspiration for my ebay build, and mine is still kicking I cant wait to get mine to a 1/4 mile track.
Your Mph is incredible! Keep doing whatever it is your doing, a little more boost and a 1.8 60" and you'll be in the 11's! |
So awesome. Is your timing map in your build thread? I'm going to look through it now.
|
Love it! The Teal Turd strikes again. :bigtu:

I backed the timing off 2°-3° last year to try to make the motor last longer. There was a noticeable drop in power so I think it's very conservative. |
Very impressive for how many shifts are involved. Seems like a 3.9 would do you good?
<----knows nothing about drag racing. |
more like a 3.6
but then his trans would call it quits shortly after I bet This is very impressive. Only other person I've seen do this on a stock engine/trans was a local guy with a 94 running a gt35r on e85. He blew his engine just a few weeks ago. Best pass was 12.0 @ 118 IIRC. Stock engine stock trans. |
Apexonyou managed 11's on a stock motor and a log manifold. 5spd, though.
|
yeah. gutted car though
and his best trap was 115 iirc so not as fast, but moves out quicker due to lighter weight and better driving |
Apexonyou did it on street tires too! He had launch control and laid down a 1.78 60', iirc. I only did a 1.94 on that run. He set things up perfectly.
The funny thing is that It's still going pig rich and hitting the boost cut before the traps so there is actually more power than what the mph indicates. The track was too busy and I only got two real runs so no tuning happened. I've been thinking about a diy traction control method that is ugly but effective. This would be particularly helpful on the street. I pucker when I get wheelspin while passing gravel trucks on a two lane highway - in fourth gear. |

I ask, because I just wonder how much boost he was running and how his stock block didn't VTA on his first pass. |
Great run, really impressive on a stock motor. Are you having to shift to 6th before the line? 3.90's would definitely help that.

This time I started with a 7500rpm rev limit and had taller tires to help the gear ratio and traction, 225/50-15's. Fifth through the traps. I've contemplated shifting to 6th but didn't have enough runs to test it out. I think it would hurt ET but give more mph, maybe. There is a lot more ET in the car, I just need to figure it out. |

I know what you mean, but that pig rich condition can actually be helping your torque curve a little, believe it or not.

What do you have in mind?
Changing rear gears isn't keeping with the bang for the buck on this car. I'll shift to 6th or raise the rev limiter unless a set of gears fall into my lap. I almost don't want to mention what I'm thinking of doing! I'll disclose if/when it works. It might be a Rue Goldberg sort of thing. If the car isn't accelerating at a certain rate in 1st/2nd gear, that indicates wheelspin. Might have to use simple sensors and electronics but I'd rather do something more fun and near free. Gotta love this: |
Very good work so far.
I think the best cheap formula to go a bit faster is a set of 24.5 x 8 inch slicks, five speed, and keep your rear gear. You want to be completely topped out just past the finish line in the 1:1 gear. The taller 1st gear of the 5 speed is much better for dragstrip duties. If you are afraid of the slicks, get the tallest drag radial that will fit on the car. You have the mph to go way in the 11's. You should be in the low 1.7's to high 1.6's 60' with the power you are making. What rpm are you launching at? |

I like slicks a LOT but I like running the DR's on the street and got used ones for cheap. I can't find half decent used slicks, I looked! I sheared a gear tooth off of the last 5sp that I ran. It was on a roll on in third gear. That run was launched at 5k. It grabbed and went. I thought I had it made so the next run I launched at 5500 and it instantly spun, immediately shifted to 2nd and it spun. People were dumping oil and coolant on the track all night. I think I was a victim of that. If the track is good, I'm positive that I can get it to the low 1.8's but to get into the 1.7's consistently, I think I need crutches. BTW, you done great things with your car. |

BTW, you done great things with your car. Do you get much wheel hop on your drag radials? Did you have any motor bog at all on your better runs? If you have not run slicks on the car, you will love them as long as you get the right size for your car. I mean LOVE them. It pretty much cured the wheel hop issues on my car. |

This run was the first of two. I didn't get to try different things and didn't do a good burnout, usually don't go for it on the first run. I agree that slicks will do miracles and I could launch with great anger and still hook up. Not sure why, but I want to run the number with tires I run on the street. |

I would not be embarrassed at all. It took many trips down the strip to get the ETs I have run.

Ya'll are gonna hate me. But my BEGi S4 puts it down. 60' 1.660 1/8 7.350 @ 93.53 1/4 11.576 @ 117.01 BFG's FTW. :loser: |

how does it help torque?

that is a seriously fast run for a basic begi s4 on pump gas. can you please make a thread about and post slip or videos?

What 60' do you get w/o launch control? I think that is my answer, besides ET Drags.
I have tried flatshift on and off. At first I was slower with flatshift because it was un-natural, but with a few runs I got faster.

No video, I didn't have a cam at that time. Pretty sure I've got a build thread here from a couple years back, car hasn't changed. |
Dude.....That's sweet. I remember reading your build thread, did you end up at 300whp?
OP: sorry for off topic questions. |

I put a MSPNP lid on the background which should work as verification. ;) No video, I didn't have a cam at that time.

I am going to have to try running a good set of drag radials.
