IRTB Driving Experience

"Flat torque curve just like my Honda S2000. Throttle response is there immediately, unlike Bob's car having to wait for the power to come on(Bob Palmblads supercharged Miata).This Miata is faster than any roots supercharger that I have driven".

--Ian Stewart, Florida SCCA National Champion Solo 2 Super Stock 2007

"FujiRacing IRTB Miata launches harder than my 280 rwhp supercharged Miata did. Fastest car I have ever driven through a slalom".

--Bob Palmblad, Florida owner of fastest forced induction Miata to this current date. National Solo 2 Tour Winner

"Fastest normally aspirated Miata I have ever driven. I have never seen a tach move so quick from 3000 RPM to redline.Perfect for autocrossing"

--Darren Disimo, Florida Top national SCCA solo driver & evolution school instructor.

"I was told that a autocrosser in California said that there was no low-midrange torque with his IRTB's.TheFujiRacing Miata has much more torque than my single throttle car. Thanks for explaining the sizing difference in IRTB kits between his IRTB kit and yours. Your product is amazing after driving the car."

"FujiRacing Miata is wicked fast is 1st in 2nd. The tach just accelerates to redline. I wasn't sure by just reading the forums. To truly understand how they work you need to drive one"

"I have the FujiRacing IRTB with the Piggyback ECU on my 1.6L Miata. It feels more like an 1.8L and from 3000-7000 RPM's is where it really goes"

Customers,enthusiasts,professional racers that have driven the FujiRacing IRTB Miata with stock internals. Actual driving is proof.

"No Supercharged hesitation or Turbo lag. Very quick out of turns. No other form of induction system matches the Throttle Response. Your IRTB kit is perfect for a lightweight good handling twin cam high revving Japanese sportscar like the Miata & S2000. A supercharged lightweight car is no match for an IRTB car.

--Peter Kawaguchi, Osaka, Japan Former Factory FormulaF3 Cart Driver

"Making your car only 200-300 pounds lighter will be only be 2-3 hundreds of a second difference. Your IRTB kit reminds me of a Weber Carb but you will definitely make more power with fuel injection. Very easy to see the results that you have after driving the car"

--Jesus Padilla (Kilo Racing) 2002,2003 & 2005 NHRA All Motor Champion

"I could not believe the the torque in the lower RPM's with the IRTB's with only 150 Wheel Horsepower coming out of the turns. The torque was like a Supercharged Miata that I have driven but with instant Throttle Response.

--Thomas Hiromoto, Dallas Texas SCCA Solo 2 CSP Georgia Natl. Tour Winner 2007
