Here are a couple of videos of the car on the dyno Dave doing his magic....



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.....

Almost forgot to mention 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 is good as the tuner mapping them and the Link/Vipec ECU does a great job controlling a rotary...

Don't give to the myth about Link/Vipec no good for rotary cars..... The Link/Vipec will work great on a rotary engine specially with a hall sensor install for timing control like a FFE kit... E85 is also a blessing for or cars....

That is some build, thanks for sharing

In with the new,. Out with the old... Vipec I88 installed and running..
