Chapo from puerto rico ran 7.9 in the 1/4 not to long ago in his FC race car! on another note the car has never seen a dyno! heres a pic of the fuel injection setup on another car.

maybe instead of an fd intake conversion I should do that... :yum:

Why hasn't anyone done a composite manifold for the Mazda?



I mean it wouldn't have the heat transfer of metal, would be easy to make.... and on and on and on.



I do like the looks of that one.

Ive been talking to some guys that have straight drad cars and they use no intercooler.........They say an intercooler does nothing for u in a quarter mile pass.....................So it is why i decided to go with no front mount from talking to them..........Weather right or wrong not sure but they go faster than i do so i listened..............The company is jim wolf my buddy is building a tubed 300z and thats were i got alot of go fast info from lets see if it pays off???????????

It looks real simple because half of the crap is not on there yet. Do you think that car will last without a belt on the alt and water pump? How about a form of spark? I see the CAS but no coils or wires. How about coolant? Where is the coolant going to go? Looks like the hole is sealed shut. Believe me, when that car is ready to run there will be a good bit more stuff under there. It will still be very simple but not quite as striped as it looks there.



If you already knew this, just ignore me!

why is there no intercooler? https://www.nopistons.com/forums/pub...IR#>/dunno.gif

don't need an intercooler if you run alcohol/methanol.

1Revvin7 01-23-2003 09:04 PM

why are there fittings/lines on the exhaust that look like they goto the fuel rail?

MAZDAROTARYPOWER 01-23-2003 11:36 PM

they are 2 injector caps that are just hanging loosely.they go in the side facing forward.
