Finally got it out to the 1/8th today.
 

2.1 60'
9.02 E.T.
84.66 MPH

Anyone want to guess what my 1/4 times and WHP might be?

That was my first run. I made another and it was like a 10 something so I stopped. Thought it was a boost leak. When I got home realized the wastegate flapper had fallen of the actuator rod.:gay:

I look forward to pulling fuel and adding timing to the base FM spark map that I'm running, I'm sure its conservative for 91, and we get 93 here. :D

high 13's, low 14's depending on the track and how you do that day. 230hp, just a guess. Don't really know how these things are, I am still thinking like a heavier car, nice though, keep the ass whooping coming to the people that think that a miata is just a little girlie car.

im thinking 195 whp and about 163 lb/ft. What kinda feel did you get on the launch what tires are you running? What RPM did you launch it at? Are you on the 4.3 rear? i would think that a 14 flat would be doable given a good launch what was your 60 ft

2.1 60' is kinda weak, get better tires and you'll break 8s easy.

Launched at 3200 and slipped the clutch a lot. It is a 4.10 with RX7 LSD. Yeah, I wasn't really going for E.T. Spun 1st and 2nd bad. Just wanted to try and see how much power it was making.

FWIW, there was a 2006 WRX STi there, and he ran an 8.4 at 82. There were several other WRXs there and an SRT4, and a supercharged Civic Si.

I had the highest MPH of all the 4 cylinder cars, a lightly modded 05 STi trapped at 83.

84 is quick man.

my guess....14.04

Well I did a little searchin and found this page:

From what the two 85mph miatas ran, it looks like I could hope for anywhere from mid 13s to high 12s. It's closest to a 1.6 FMII at 15psi. Sweet.
Here's a datalog from the run. You can see by the RPM the traction problems it had in 1st and 2nd.

ya i was gonna say, a boosted miata @12 psi runs with sti's powerwise and they are about 13.5s quarter mile times down to 13-high 12's with a lil tuning and better driving. I would have to say you are probably very close to your high 12/low 13s estimate.

oh i C the 60 yeah 2.1 is killing you. needs more traction.

220-240whp. 84mph is not bad at all for a GT2560R @ 12psi

Means a lot coming from the HP king himself. Maybe my downpipe is actually paying off. :D

HP king? Not even close;) Once the hydra goes on Im looking for about 350whp....that will be a lot more fun.
