my kid sierra has gone twice to the track and managed to go 14.4 @97mph we learned later the car would no hold more then 4lbs of boost on the dyno. car has a serious boost leak. goal for this car is 12lbs of boost.



mods are:

streetport engine

cleaned,balanced and calibrated primary injectors and resized secondary injectors

walbro255 fuel pump

bronze clutch

3inch downpipe

fuel cut defenser

thats about it. this car is using a series 4 engine and everything else series 5.

at the track..

you could follow her build at the shops facebook page.. advanced rotary performance somewhere in fb somehow the fb page is hard to find.

I have some youtube vids but i can't find a way to post them..i'll keep updating her progress...

Is this it? https://www.facebook.com/AdvancedRotary

Wow. That's not too shabby. What tires is she running? Any wheel hop?

i think you found the page. but that link you put up doesn't work

tires are kuhmo 225/50/16

It's not a fan page it's an actual page for the shop. Do a search (of everyone not pages) of "arp shop"

the dyno runs.. 3 to 4 psi and 10.0 Air fuel ratios.. 210rwhp

hi judge ito san i have been reading up on your porting school threadsand others with much admiration with the quality workmanship and power outputs that your achiving i myself has been building and racing rotary powered cars here in new zealand for te last 15 p.lus years im very intrested to try some of your ports in my new race motor that im preparing f or my gen 3 curcuit car we as a rule have never run ports with radical port timing as you we tend to u se the trusted racebeat templating withabove average results and reliability i see that most of your motorsport is drag racing would your radical ports suit curcuit racing is there any chance we could get some diamensions or templates so we can try them

update on Sierra's Rx-7, i fixed the boost leak and dynoed the car at 9psi. car made 280rwhp, anything over 9psi and it would lean out real bad so i kept it at 9lbs of boost. we took the car to our local race track and she ran 13.0@104mph with a 1.7 60ft mark

the rookie about to run her 12.8's

Attachment 16235

here is a video of her 12.8 run, the loud noise behind her was a rotary powered toyota starlet also testing that day.. on this run you could see how she over revved it,(between 2nd gear and 3rd gear) hitting the rev limiter and slowing the car down. this Rx-7 has more in it.
