My Turbo Prelude
SONG IS NOT MINE IT'S "STOP (blue mix) by Ghost_K. All the work on the car was done by my father and myself. It's 97' Prelude 5th gen H22A4, it's engine insides are stock (and its staying that way HONDA KNOWS WHAT IT DOES) I've heard of a lot of people who start seeing problems when they open up the engine, I'm not going to risk it this is my every day ride and my car. I really don't know why people say H22's can't be Boosted, mine has handled it very well, it has not given em a single problem and it has been Boosted for almost 2 yrs now, the first year it lived as you see in the video at 8 psi of Boost. These days it does have more mods in it, like a proper Boost controller, an AEM fuel rail and fuel pressure regulator, NGK iridium plugs and spark plugs cables, and 550 RC fuel injectors, it's also running 12 psi of Boost now, it Dynoed 364whp (sorry i did not have my camera with me at the time, sister broke it, but the Dyno paper is laying around somewhere in my room if I find it I will post it). I will stick with these numbers until I get better traction, ideas are welcomed, i don't like spinning my tires till 3rd upper RPMs. I have not timed it but i did stay neck and neck with a Civic Si turbo (2006 model) of a friend of mine which runs about 12.3 secs, it was rolling of course because of my traction issue, but I still find my car quite fast and extremely reliable for an every day car. HONDA FOR LIFE.
Blitz Venturi Drive Super Sound Blow Off Valve
Introducing the new "Venturi Drive Super Sound Blow Off Valve"
The all new ribbed main body dissipates heat more effectively and the venturi shaped funnel creates a sharp dynamic sound.
Venturi Drive dump valves also feature "Dual Drive" for maximum response, a small port for low Boost and a larger port for high Boost.
The main purpose of the dump valves is to improve the response of the turbo by quickly releasing the Boost pressure before the turbo stalls.
They are made from die cast polished aluminium with a brass piston and a rubber diaphragm, meaning they can easily cope with Boost pressures up to 1.2 bar with the supplied spring.
There is an alternative hard spring for Boost pressures above 1.2bar and also a soft spring available for very low Boost applications. (please see DV Spares)
They are also tension adjustable.
All dump valve kits come with a comprehensive fitting kit tailor made to fit your vehicle.
