Hard work pays off …. Thanks to Eric Gerardo Monzon Rotarywerks great engine built and my tuner David Heerdegen from Dtechmotorsport. 
We have a very reliable (7 seconds 1/8 mile 10’s seconds 1/4 mile mile car) with stock OEM GSL-SE diff and stock OEM 14's inch rims with 205/50/14 drag radial…. 
The car is only running 18 psi of boost do to the stock diff..

Mission accomplished for stage 1..... More to come..... Having a 30 year old street car that gives you this type off excitement and at the same time is a beauty and fun to drive on the street is priceless.....

 

This engine has more than 30 dyno passes at 500whp+ and hundreds of street pulls with the tune on the Vipec V88 and has never miss a beat... This engine are good as the tuner mapping them and the Link/Vipec ECU does a great job controlling a rotary...

We did some tuning on Tuesday and fix some boost control issue we had with some vacuum hoses..

Now we got everything working great .. look at the boost target and boost line ... Yo can also see my 3 wide bands set up.. Sensor on each runner and one in the down pipe (white line)....

Thank to Dave from  Dtech Motorsport from New Zealand for his great remote tune like always...

Car is running Strong.. 251 KPA about 22 psi boost ..  540 whp on a mustang dyno (heart braker dyno)..
