K series Miata swap
#602
Yeah I saw a K series acura with a full-race manifold and and 83whateverEFR dyno to 650whp on e85 with almost a 4k rpm wide powerband, of course it was 5k to 9k and I doubt that thing hooked up on the crappy walmart street tires it was on it any gear (that thing was strapped down so tight it was on the bump stops and had half a gallon of VHT on the rollers) but still. (Seriously, I hate car people that arent racers, they spend crazy money on the motor then put the cheapest all seasons they can find on their $3000 wheels, I mean RimZ).

Yeah boost by gear would be perfect, provided you can set up hondata to read vehicle speed some how, with a mechanical speedo drive and no abs on the car I'm not quite sure how to do that.
And would it really be any good to for the weak 4th gear in a 6 speed? i would think by 4th gear you would be putting down all the power.

-The early cars have a speed sensor built into the dash regardless of ABS or not. I am running that at the moment but am not having good luck with it.
-Before my T5 swap I ran a MSD speed sensor on the end of the speedometer cable on the transmission end. That worked well from ~10mph on.
-like stinkymonky said, you can get creative and install a hall sensor that picks up something, say the 4 bolts that attach the driveshaft to the diff. That's what i'm planning on next.
I was running a speed sensor to turn off my 2-stage/antilag above a certain MPH, but now using it to limit boost below certain MPH would be a good idea.
I must always make no torque but I don't have much issue in 3rd and above with a 205 tire and i'm probably around 400hp (). first is useless but that's normal for any turbo miata, and second still makes the car go fast it just makes more tire noises while going fast. It's not like you go no where and it gives the sensation of still accelerating harder than no wheel spin/lower boost.

My plan with this set up was a rotrex charger, rotrex = less torque. That will not fit, so I will use turbo. I already have advanti's with 205 direzza dz102. I will not buy expensive race rubber to commute back and forth to work(70 min total) with so I can have 225. When someone makes a 225 street tire I will upgrade. All I'm
Getting at is if I go turbo I will have torque in the breaking range of a 6speed so I hope the 205 saves the tranny.
Just like honda drag racers use stock axles so they break insead of a tranny.
Yes I drift also why I'm not so worried about loss of traction. I don't want to be another lost soul in the "my transmission took out my anus cause I'm running 275 slicks with 400 ftlbs " thread
