SO you saying I am lieing? There are cars beating bikes every day!! If your car can beat a bike 600cc and up your car is fast. We had no traction problems with the drag radials lol, it all come down to your setup. Plus we had more than 400whp.

I know you can’t believe it, my friend with the R1 could not too!!! he was saying, the first race he did not down shift but the next race he did, and we were side by side with him all the way to 5th gear.

People keep saying 2jz’s are DYNO Queens, please!!! so are big blocks.

We are not hating SR20 guys, we have some fast SR20 in the crew.
