Blitz D1 Spec Dual SBC i-D - Super Street Magazine

Whenever people say we have too much time on our hands, more often than not they're right. It's amazing how we always wait until the last minute to get anything done. That's like the story of our existence. Strangely enough, there are some things we do plan ahead of time: our project cars. For the most part, they're all pretty well planned out. It's the execution that kind of gets lost along the way, not to mention we don't really have a garage where we can work on these cars. But we still manage to get these cars done miraculously, which we think earns us the applause from the back row, don't you?

Blitz D1 Spec Dual SBC i-D and Power MeterWe know what you're thinking. An update on Ricky's Nissan, that's unheard of. But, yes, it's true. After almost 10 years of building his car, we didn't think there was actually space left to add more parts. We were right-kinda. He didn't exactly add new parts, he replaced some older ones. For quite some time, Ricky had been using a Dual SBC i-D boost controller and a Power Meter from Blitz. After going through several different testing periods, he found that increased turbo response from using two solenoids was to his liking. The D1 Spec versions come in a pearl white and blue casing to match Ken "Nomuken" Nomura's R34 Skyline color scheme. Oh yeah, did we forget to mention that these are a limited production run to promote Nomuken's company, Uras, and his D1 car? But aside from the color and a few little screen extras like his signature monkey face, the R34 drift car, and the Uras logo, these are pretty much the same as the original units.

In our Sept. '01 issue, we did a story covering the different boost controllers that are available in our market. Some use solenoids and others use stepping motors to alter the pressure to the wastegate. The Dual SBC i-D uses solenoids, two of them, hence the abbreviation for Dual Solenoid Boost Controller. This simply means that there are two solenoids working together like an open/close switch. They hold the pressure in until a preset limit is hit, then release, which helps provide extremely quick turbo response. There are auto and manual modes for setting the boost pressure. Auto allows the user to dial in the desired boost pressure in either psi or bar. Set it and forget it. We've never heard of anyone having problems with boost spike or over boosting while in auto mode. Using auto, however, delays the response of the turbo just slightly. That can be somewhat corrected by fiddling with the gain setting, but we don't recommend screwing with that too much. Manual mode is for the hard-cores. This takes a little more time to program because you'll need to drive around and play with the boost and gain settings until you reach the desired level. Ricky made sure he exercised extreme caution when setting his, so remember to do the same. Just using the Dual SBC i-D by itself is satisfying enough. There are four channels you can set up separately for different types of driving, but once you throw in the Power Meter, you've unlocked a ton of other options like speed mapping, which lets you program it to automatically switch between the channels for different boost pressures in accordance to the vehicle speed. Also, the Power Meter works as an onboard dynamometer, calculating horsepower through speed and acceleration. There are a ton of other things you can play with too like lap and dragstrip times. You just have to spend an hour or so programming it all. Remember, these Power Meters are limited editions, so once Blitz runs out, you're SOL. Also available in the D1 lineup are the Full Auto Turbo Timer, air filter, and full DC gauges.

Unorthodox Racing Clutch and FlywheelWe figured it was time to do something to Roel's Corolla besides let it sit on G4, collect dust, and inflate the driver-side front tire when it goes flat. He has some big plans for this car, but they're moving at Jonny pace. Ro and "old-school" Yamz have been planning the outcome of this car for the past few months. In between their Houdini session, we overheard talks of a complete paint and body makeover, a fully built 20-valve motor, stand-alone engine management, coilovers, and a fender that doesn't hang up the door when you open it. In Yamz' head, the Corolla is already complete. To the rest of us, it's still the red thing Roel limped back to the office with massive rod knock.

With the amount of power that Ro is planning for the car, there's no way the stock clutch will be able to handle the abuse. So, yet again, we had to turn to Unorthodox Racing for assistance. It was recommended that we use one of the company's racing clutches from the Ultra G line. The four-button setup that Ro chose to go with will be able to handle way more power than he's expecting to make. The sprung hub will help absorb the chatter that's notorious in race setups. The aluminum flywheel from UR's Ultra L line weighs in at just 11 pounds. It's made out of CNC-machined 6061-T6 aluminum and can work with any stock or aftermarket clutch. Whether the Flip decides to go boosted or naturally aspirated, this will definitely get the engine revs up faster.
