Well most times it's really hard to tell if someone is being facetious. I know a lot of people with PHD's that don't know how to change a tire.


Delslow keep of the good work. I may be contacting you in the furture for some machine work. I'm thinking about adding a couple more dowel pins to my 20b.

 

great work,
I am new to rotary world so I hear pp is not daily driver friendly,
how bout pp with good size twin screw charger and water to air cooler,
kind of like pettit rx8 setup but larger compressor and cooler and
much more boost, will that make it idle better and give it good low end
torque for daily driving?

also can the pp's be moved higher or lower to shift the torque lower kind of
like adjustable cam pulleys, so i can have a good fllowing 9k rpm engine?

this work of art pp delslow is doing gave me this idea

 

Welded the velocity stacks into the plenum tubing over the weekend.


Sawed the tubing in half at work, then traced the velo stack shape onto the tubing and cut it out with a die grinder:



Made a makeshift fixture to get everything squared up and tack welded:



Welded up(Pain in the ***!):




Inside roughed out:



Inside shaped/sanded to 300 grit and ready for hand finishing:

 

beautiful!!

 

teach me.

 

Fantastic!

 

where did you buy all your metal?
What is your approximate budget for this project?

 

wow some awsome work man keep it up and keep us posted.

 

Wow, some guys on this forum never cease to amaze me




=Ben

 

Damn Del Slow why for the love of god don't you live in Oregon. On a serious note kick *** work!!!

 

Keep it up Delslow. My next "big project" will be something similar.

Are you going to put injectors on the intake plenum directly inline with those two nice big velocity stacks?

 

how much boost to you plan to cram into this motor? (please say upwards or 30psi! )

 

he wont need as much boost anymore... could probably max out most turbos now under or right at 30ish psi

 

dude I have never seen a "fast" rx-7 with a blower. I'm sure there are some decently quick ones out there, but I've never seen one even break the 400whp barrier. And this car should DECIMATE that. If you are doing a pp you are not building for daily driving!

 

HaHa! You must be kidding or not be logical. When the bars are at the narrowest, it is empty. When they are largest, it is full. HaHa!

 

there is a local guy that was puting down over 400whp out of 1.5 ltr d series honda engine with not that big modified roots type eaton M-62 supercharger

I dont see y 13b with more room for bigger, better, new tecnology, twin screw blower shouldn't do it

sorry I got little off topic

 

I get most of my metal from either Research Alloys(scrapyard in Columbus) or at my job. I bought a few things retail from a local supplier in Cinci, but they raped me so I won't be using them again.


No, they will be in bungs placed along the runners, both before and after the TB.



I got a bit more work done on the TBs.

Machined o-ring grooves in the TB for the flanges and machined out extra material in the middle:



Machined o-ring grooves in the endcaps:



Machined the bores and boltholes in a piece of aluminum for runner flanges:



Turned down the barrels to size and started to bore one of them out, but didn't have time to finish:



Still have quite a bit of work to do to them, but I hope to have them mostly complete next week.

 

sweet

 

Sickkkkkkkk

 

looking nice..

 

Skills...

 

Awsome project, but why can't you americans learn how to use metric measurments instead of 3 or 4 decimals? haha... crazy americans

 

^ I agree. I love America and all but it sure is alot easier when everything is divisible by 10! ENGLISH UNITS SUCK!

 

True that metric is so much better.

 

deviding 3 place decimals by 10 is easy in inches... (hint, move decimal place left)
