As some of you may know, my ISF was used as RR-Racings test mule for the soon to be releases "Street Kit". I have had the car back for about a month now and racked about 1500 miles and couldn't be happier with the results.
First lets start with the company:
I have nothing but good things to say about Rafi and his team at RR-Racing. I trailered the car from Chicago to PA and got to chance to bs with him and even go for a ride in his blue car. The guy knows his stuff and has built one hell of a track car with his ISF. The entire 5 week process of development felt long due to the excitement but was to be expected as the kit didn't exist when I dropped the car off. I had updates on the vehicle and if problems occurred I was made aware. I would have zero hesitation referring someone to RR-Racing after my experience was said and done.
On to the kit:
This street kit doesn't have a intercooler so the throttle response is just insane. The supercharger comes on quick and has smooth linear power all the way through red line. THIS THING JUST KEEPS PULLING AND PULLING! The install is very clean and frankly mind blowing when you pop the hood and you see what little room everything has. Because of the no intercooler, you have to either blend E85 or go with a meth injection kit to help with air temp cooling. Being from Illinois I went with the 93/E85 blend because its just everywhere but also opted to go with the meth kit as well just incase I don't feel like blending. If your worried about blending don't be! We installed a Ethanol content cause thats makes getting that perfect percentage easy every time. Rafi tested both scenarios and achieved 545 WHP on E37 and 525 WHP on meth. So that's about 130WHP over FBO and a tune. He not only dyne tuned it but he tweaked it a bit on the street as well. He personally drove the car daily for a bit to make sure everything was ok which I though was incredible and shows he actually cares about what he puts his name on. All in all I wouldn't hesitate buying this kit again. Its super reliable and incredibly safe as I watch and record all engine data through Techstream from time to time. Every ISF owner needs this kit its literally night and day. If your on the fence and close to Chicago hit me up and I'll take you for a rip!
Recently I joined a friend at Import Face Off and the car nailed down a 11.4 at 124 MPH. Keep in mind the the car is running heavy Avant Garde wheels and Continental DW street tires on that run. If you watch the video posted below you can hear the traction issues. All in all I wouldn't hesitate buying this kit. Its super reliable and incredibly safe as I watch and record all engine data through Techstream. Every ISF owner needs this kit.

Obviously has more than just those items if you look at the exterior but for performance thats it
1. You should have an intercooler on there unless you’re running methanol 100% of the time. And, quite frankly, it just shows me that the shop does poor quality designs if they’re okay with not designing it: it’s the lazy way to make these. It makes install easier with the very detrimental risk of extremely high IATs. And it’s not going to greatly impact throttle response, either.
2. 130whp gain with a blower WITH methanol is pretty bad. Those are numbers you would expect from a small blower with low boost, on 93, and no methanol.
I’ve made bigger gains from a P1 on 8 psi with no methanol.
Honestly, you should have expected in the high 500whp or low 600whp range with methanol. So, please don’t be impressed by this work, it’s pretty mediocre. These are the gains you get from $3,500 blower kits like Torqstorm.
Another negative post from this non ISF owner (who spends an awful lot of time in this forum, with nothing good to say about the ISF). Haven't figured out why he is he is here honestly.
It still looks good, sure it would have been nicer to stay closer to the curve of the tube right there, but to me you managed to retain aesthetics while still primarily pushing for function, win-win
Big thanks to Nick for bringing his car out to our shop, and also for his patience as we worked out a few bugs!
I have personally driven Nicks car extensively on the road, and had an absolute blast driving it. At the current power level, it really is a good balance appropriate for a daily driven ISF, not too powerful that it becomes maniacal, and plenty powerful enough to make it a legitimately fast car. On one of my tuning runs in Mexico, some dude in a Alfa Guilia Quadrifolglio tried to keep up, but it wasn't even close. The Guilia is no slouch, and is certainly a seriously fast sedan.
Anyway, we are working out some bugs on our website, so the Street kit should be listed soon on our "Power Upgrades" category for the ISF.

Can we get itemized response to dispute these from RR Racing? It'd certainly ease the minds of potential customers such as me.

If you have technical questions, you are welcome to call us, ask for me, and I’d be happy to answer them.
That said, if I replied to every armchair expert on the Internet, I would go out of my mind. Let us just say that “expert” who offered his opinion, at a minimum, doesn’t have an ISF and doesn’t have any experience tuning an ISF. He also apparently hasn’t heard of RR Racing and the vast tuning and forced induction development we have have with Lexus ISF, RCF, etc. We (RR Racing) didn’t just pop up yesterday, we have many v8 supercharged customers who can attest to the quality of our products. Our tech posts, dyno charts, and positive testimonials are all over Clublexus, more than any other vendor by a wide margin.
Regarding Methanol/water injection. These systems are extremely common throughout the aftermarket industry. Even stock BMW M4 GTS comes with water injection system which allows them to run more boost and power on pump gas.
If you don’t trust yourself, the water/meth system can easily be setup to cut boost in the event you run out of fluid, or there is some technical fault.
Our gains with our new entry level street kit are absolutely great and on par with similar non-intercooled offerings from reputable BMW E92 v8 tuners like ECS (their m3 v8 base kit is also non-intercooled)

Exactly what he said I monitor my intake temps through Techstream and I have never had a concern. Now granted I don't beat on the car or take it to the road course but if you plan to do that you should be getting the intercooler upgrade anyhow.
This is a company thats dedicated to the F platform not Vivid Racing or some junk company
