RR Racing Supercharger
i have noticed that.. RCF is definitely a top end car. It feels
much more planted at 100+ speeds. But much slower off the line.
I will consider doing an sc in the RC since I don't have to smog it for a while
I was sent a different tune and the car feels much better now, I believe the other one was too conservative where the car just didn't make much power. If anyone wants to check out the car in person I have no problem meeting up it, it is by no means a show car, but at least you can get an idea of what it is.
where are you located in california?

I think he said that he would need an SFI jacket. At my track faster than 11.49 you need the following:
- SFI 1.1 or 1.2 Flywheel / Clutch
- SFI 6.1, 6.2, 6.3 or 9.1 Flywheel shield
- SFI 3.2A/1 approved jacket
- Roll bar
- SFI approved seat belts
- Drive Line Loop with street tires
- Full Leathers on M/C, ATV and Snowmobile @ 120 MPH
To fwdGTP, thanks for the videos of your quarter mile & timeslip. Man, can't stop viewing your run to see you cross the line well into 5th gear. Your car's speed validates RRR's horsepower claims.
Did you have to add any additional safety equipment to the car to run faster than 11.50 at your track?

I previously ran 11.75 @ 119 NA, although that was under almost perfect weather conditions, with weight reduction, IS350 Differential (way shorter than stock), and drag radials. On stock rearend under normal conditions the car ran 12.1 @ 117 iirc. So realistically it's about 10 mph and 1 sec decrease in 1/4 mile.

Weight reduction.
Is anyone gutting their SCs before hitting the 1/4 mile or what? I have not seen one post about I'm sure if your were able to shave her down to 3500lbs she would be a damn predator, sleeper if you will. Idk tho anyone?

it would definately make a difference. I personally wouldn’t want to give up as much as would be required to drop to that weight. It would be much easier if you don’t have a sunroof.
There are cars without sunroofs, and if you wanted to remove the sunroof, all the design work is done, parts are available from Lexus, etc. You'll get more headroom for your helmet too. It just won't be cheap. I've seen a few Supra guys do this to convert a targa top car to a hardtop (like mine is).

I would love more helmit room. Every time I line up I have to contort a little to get mine on, then can’t lean forward with it on.
If I were building my car into an all out race car, I would do this. In the end, I like the luxury side of the F and think the cost may not outweigh the benefits. We have a member with a carbon roof that seems to love it. He races his all of the time I believe.
