RR Racing is continuing to improve the power of its RR780 supercharger kits for Lexus RCF and GSF and set new records. Last month we tuned our RR780 Stage 4 RCF supercharger kit to make a record 739whp and 557-wheel torque!
It has been over five years since we first tuned and supercharged the Lexus RCF, and we are very grateful for all the support we received from the Lexus RCF community over the years! This month PPE shipped us prototype of their catted racing headers for Lexus RCF (using 400 cel GESI EPA cats) for our testing and development. We decided to use this opportunity to perform the most transparent and thorough testing of RCF mods. This was especially revealing given the recent trend with some tuners who have released grandiose claims (of up 20-30 hp gains!) by playing tricks with Dyno testing, showing unrealistically low baseline dyno results, and in general advertising dyno results with very little clarity or transparency in what was done.
If you are interested in understanding true RCF performance, you will read carefully this article.

This program runs on MotorTrend cable channel or streaming on MotorTrend TV.
In March we completed two exciting new Porsche supercharger builds for 991 GTS and 991 Targa 4S. The list of Porsche 991 models that get more power from RR Racing keeps growing!
RR Racing is giving birth to another supercharger kit! This time this is a more affordable variation of our RCF RR670 kit — the RCF RR670 Street kit.
The IS250 is finally gets its long-overdue power with our release of the supercharger kit for Lexus IS250. With our Stage 2 pulley and optional ethanol or methanol add-ons, IS250 makes a whooping 370 wheel horsepower more than doubling the stock engine power!
We promised last year to release stage 2 tuning for our 3XX supercharger kit for Lexus IS300/350, RC300/350 and GS350 models and we now delivered for the AWD vehicles!
