Will stock rad fans work with a D1 blower ? I was going to stand my rad up but I can't hack-up my car like that.
Also I'm cutting a hole in the front bumper to feed the intercooler with fresh air. Will that make the car run cooler or is there not enough air flow to make a difference. I did remove all the plastics and washer bottle hoping it would help cooling.

 

Run fine w/ the factory stuff on my F1. Don't see why you'd be any different.

 

Everything fit fine with my D1SC and a 8 rib setup.

When I went to a F1a and a 12 rib, I had to hammer the frame, and move the radiator/fans forward just a bit.

 

I ran stock fans no hammer mods. I built alluminum spacers for the bolts on the driver side to move the fan closer to the radiator. it gave me the 1/4" i needed.

 

As ramair96ws6 said just make you some 1/4in spacers and move the fans closer to the radiator and you will be fine. I actually used a couple of aluminum tubing cut in 1/4 spacers for mine.
