Rb25de (supercharged) Project

[FineLine]

You know it mike.Had a look at some of their new toys the other day. Oh my!!!

haha I'm here! Yeah, Noel and Mike are spot on. Im stretched a little thin atm. However I have fixed the issues I had on the dyno the first time. Its just a matter of getting time to go back to finish off the tuning. Currently fabricating a whole exhaust system on my old mans HR holden w/ stroked LS1 to 383CI, then I have my uncles 56' chevy to fit new 434CI stroked small block into and fab up exhaust system and fuel system. After that is Dads 57' chevy which a 632CI BBC with a 4L80e box to go into it and then exhaust system and fuel system to suit. The two Chevy's need to be done before April for a charity event we were hoping to attend at Harry's.

So my car has gone on the burner again until further notice unfortunately! If I get some time in the next couple of weeks I will attempt to get it tuned!

Any updates?

[Trozzle]

Wooooo you dug this one up!! I kept meaning to find it and inquire myself, lol

Sorry to say fellas that I ended up quitting on this. I did finish it and got it all going, but it was an absolute pig to drive. I couldn't get the change over from off boost to on boost with the bypass valve to work very well. I spent a fair bit of time trying different valves and setups trying to make it more drive-able. It was just taking too long to try and get it to a level where I would be happy with it.

My apologies for the disappointment peoples! If I had more free time and absolutely no social life or girlfriend then I would attempt to perfect it all, but this is just not feasible. I really hate to be a quitter...its killed me a little on the inside not being able to get it all to work how I was hoping.

Anyway. the car is on the back burner at the moment. The back up plan is to go to a big single and just pump out some laggy horsepower for fun.... of course when time presents itself!

Did you consider putting the throttle between the 2 chargers, obviously you cant intercool the supercharger then though

How does every other supercharger in the world work then, they don't seem to have any fancy things to make them idle ok, do they all just have a low speed air bypass valve or something?

Even if you just wired a recirculation line with a very small bore eg 1/2 inch from the intake to the discharge this would recirculate air at idle and at high boost would only recirculate a little bit.
