Just got back from the dyno.
Im running a Begi cast manifold stainless downpipe, 3 inch cat and exhaust.
My injectors are getting closed to maxed out and my IAT were rising due to my small BegiS intercooler so I limited boost to 11 to 12psi and very conservative timing on 93 octane.

Looks pretty good to me for 11psi. That turbo should really wake up with a little bit more boost

what injector size were you running to max them out at that hp?

Rx7 460s with a stock fuel pump. I have some room left but I don't want to go over 80% duty.

Looks awsome. Im hoping for similar numbers on my tubular manifold on a 1.6

me too, which is why i am worried about if my RC440's will be enough now.

Very nice! I decided to build a setup with this turbo. I have both .86 & .64 tial turbines and hopefully will work with a dyno shop that will let me dyno both the same day for the same fee.

I wouldnt be disappointed with those numbers..

Since I had a couple people ask:
The tuning was done on a dynapack dyno at evans tuning in PA (right across the delaware river from Route 80) Jeff Evans is an awesome tuner and very familar with the AEM EMS.

Cool! Nice Job!

High numbers, better than me with the same equipment and less manifold pressure...probably because of my low static compression.

BTW, that turbo doesn't start to shine until 15+psi though. 15psi through mine would put me well into 300whp on a dynojet.

Great numbers! I'm hoping for something very similar with my new setup (on its way).

what are you running for engine managment?

If you dont mind me asking, how much did you pay and how long did he take to tune? Im looking to tune spark on mine and rt 80 is only about an hour and a half away.

Nice !

My next turbo will be the gt28rs. Hopefully Tim will have done enough testing to determine which size turbine is better by the time I'm ready to buy .

It'll also mean i'll be suck with the turbine that doesn't work as well.

Jeff charges a flat fee of $600 to setup/tune an AEM EMS. I think his hourly rate for retunes/dyno is $150 an hour. Id give them a call or email them to find out more. They also give pretty nice discounts if you buy the EMS from them and get it tuned. It would have actually been much cheaper for me to have just bought the EMS from him in the first place.

As for time on the dyno, we started around 11:30am and we were off the dyno at around 4pm and then spent another 15 mins or so checking how the car did just driving around town. I think everything could have been done faster but I kept having weird wastegate/boost solenoid issues which slowed us down.

My car would either boost really steady at 10psi, then after changing the duty cycle by like 1% on the boost solenoid my car would all of a sudden boost all the way to boost/fuel cut (14.5psi). My MAC solenoid that Im running doesnt seem to like to run more than 50% duty cycle. Boost would climb steadily if I adjusted all the way to 50%, but when I even changed it to 51%, it would go all the way to fuel cut. Took some time fiddling with the actuator tension to get it to be a stable 11 to 12 psi

Yeah, I know this turbo really shines in the 15 to 20psi range. Now I just need to build my motor, get larger injectors, get larger intercooler, get an Absurdflow, a V-band housing and retune.

It really sucks that with the log manifold, stock head, etc I can barely run any timing compared to what guys running nicer manifolds and bigger housings can.
