lol..my mistake...

 

rotaman99- there are a lot of tips, tricks, techniques, preferences, theories, beliefs, etc... on porting in general.

 

I know there are a lot of tips and tricks and such on porting in general, I have already good good tips on the intake ports but the exhaust port I always see the same thing. Just making it bigger without any knowledge of why they ported the way they did. So no one knows?

 

i read its the same as the intake ports, your smoothing them out so that way you can have a scaveging effect, so therefore youre getting as much exhaust out and taking in as much A/F mixture as possible...for a good flow, so there wont be a restriction as exhaust exits the ports( correct me if im wrong)...blake from pineapple racing has 2 articles in mazdasport mag about porting theory on rotaries....its somewhere on the forum..

 

I dont know much about porting at all, but the work i did ended up really good! I followed a picture i found on thaaa internet! hehe

 

lol...

 

I need to make me 1 of the engine stand adapters, sucks workin on a bench.

 

when you port the exhaust, you can port it to open earlier, close later, or both depending on how you want it to flow for your specific setup.


the engine stand adapter you can make it or get it from pineapple racing for about $60

 

you can weld your own stand adapter in 10min.. Not really high tech :P
Nice project ivegonemad!

 

Well the scavending effect comes from when you have a properly tuned merged exhaust system. The exhaust pulse from one rotor will flow by the other rotors exhaust runner with positive pressure in the front of the pulse while there is negitive pressure in the rear of the pulse which is what "pulls" the positive pressure exhaust pulse from the other rotor and initially gives you the "scavenging effect".

rounding the edges im sure would help pull more exhaust out.

If you close it to late, you could pollute the intake, or if you have it open to early, you could loose some of your combustion energy and loose power? These are just guess's by the way.

 

i hate taking the sound deadening off i did it with a scraper and a hammer...lol...

it wasnt worth the time and trouble though...

 

^haha. Just consider it a rite of passage for your track car.

 

Next time you`ll use some dry ice and a hammer
So much easier and you can do other stuff with the car as the ice cools the sound deadening

 

Yep, dry ice method owns all other.

 

i bet it does, i just felt lazy driving 30 miles to get some dry ice no where local sells them and the guys with ice cream trucks didnt bother selling me some...lol..oh well..

 

so alot has been going on duringthe past months and now i have a new track car and some goodies!!! to begin im finishing the car i have aquired(used to be my cousins) now its mine..lol... heres a couple of pics of the new car...






it was t2 swapped but the engine blew so he was bitchin that rx7's blow and they guzzle gas....etc, etc..same old yapping, so

from this


to this:




it still needs a couple more things, wastegate, ecu, DP, fuel pump, and we can fire this bad boy....t70 turbo so lets see how it goes...

 

That fuel system work out ok for you Alex?

 

awww no banana car? im quite upset

 

it worked great!!!! hey dont forget that i still need you to do some stuff, im just saving up for a bit of extra work needed....

 

no more sad: i had to save this car and i have worked on the car since the day my cousin got(except for the t2 swap) and i drove it and fell in love, and itll be 4x better than the banana

 

how come your selling it?? what happened exactly. I saw your car at lucky7 with the bumper torn off...
