datsunfreak Posted May 27, 2017 Report Share Posted May 27, 2017 It is over kill for sure. The blower would give instant boost till the turbos spooled. Then it gets ridiculous I'm talking about the big thing on top with the three blue butterflies (don't know its real name, always called it a bug shovel). It can't possibly be doing anything. If it is part of the intake, when it opened you'd lose all boost pressure... Maybe it's some kinda of blow off valve... :rofl: Quote Link to comment

There are positive displacement rotors below the bug catcher. The crank turns the rotors and compresses air into the intake. You make 300 HP but it takes 120hp to turn the rotors. Makes instant boost but robs power when not used. Quote Link to comment

Yes, we know, but what is the three butterfly intake for? Considering the two turbos drawing through the two carbs with air filters on top... Quote Link to comment
thisismatt Posted May 28, 2017 Report Share Posted May 28, 2017 If you’re looking at the butterflies on the injector scoop and wondering how they function with the turbochargers providing boost upstream, they don’t. The injector has a divider behind the butterflies that seals the boosted intake. Despite the fact that the carburetors are so far from the intake plenum, Dobbertin did indeed tune the car to run with that wild induction system. From hotrod.com 2 Quote Link to comment

datzenmike Posted May 29, 2017 Report Share Posted May 29, 2017 The three 'butterflies' are throttle plates to regulate the air into the SC. How else would you tell it to go or stop? Quote Link to comment
thisismatt Posted May 29, 2017 Report Share Posted May 29, 2017 So the butterflies are adding air to the already mixed a/f from the draw through turbo-carb setup? What kind of valving is keeping the pressurized air from backfeeding either the SC or the turbos/carbs? Quote Link to comment
datzenmike Posted May 29, 2017 Report Share Posted May 29, 2017 No Idea Matt. It's like that SC on Mad Max that suddenly clicks on. Looks like making 7 the hard way Quote Link to comment

datsunfreak Posted May 29, 2017 Report Share Posted May 29, 2017 The three 'butterflies' are throttle plates to regulate the air into the SC. How else would you tell it to go or stop? The throttle blades on the two carburetors. That's how. ^_^ What kind of valving is keeping the pressurized air from backfeeding either the SC or the turbos/carbs? Exactly. That's how I know it's just for looks. American car version of "ricer shit"... Quote Link to comment
datzenmike Posted May 30, 2017 Report Share Posted May 30, 2017 I don't know how you would stop the SC pushing air back out the turbos at low speed. Maybe something like a reed valve. The SC would hold it closed at low speed, once boosting they would make more than the SC and push past it. Air can't go out the SC it's one way in only. The throttle plates on the SC also have fuel injectors (or fuel and nitrous) so it's not just the two carbs on the turbos. Like I said..... 7 the hard way. Quote Link to comment
goes2fast Posted May 30, 2017 Report Share Posted May 30, 2017 The bug catcher has to be a phony, no fuel lines going to it. The butterflys have to be blocked off to keep boost from the turbos from leaking out, and the whole unit is being used just to direct air from the turbos to the blower. It's a show car, not practical for making real power. :no: 1 Quote Link to comment
Mattndew76 Posted May 31, 2017 Report Share Posted May 31, 2017 Anyone notice the turnbuckle leading from the radiator shroud to the butterfly lever? The breather is a fake item for show. Just glorified pressure box now. Quote Link to comment
a.d._510_n_ok Posted May 31, 2017 Report Share Posted May 31, 2017 Car Owner Completes DIY Engine Rebuild Dealer Said Would Cost $57,000 This is the most complex way of avoiding dealership parts markup we've ever seen. Back in January, we told you about an unfortunate Mercedes-Benz R63 AMG owner who, instead of paying $57,000 to have the engine rebuilt after a head bolt failure, decided to do all the work on his own. We're happy to report that after eight months of work, the owner has finally put the car back together. It was back in September of 2016 that Grassroots Motorsports forum member mazdeuce was faced with the massive repair estimate from his local Mercedes dealership after the engine failed at 106,000 miles. Instead of forking over the insane dollar amount to fix his precious unicorn, mazdeuce decided to buy a lift and do it himself. http://www.popularmechanics.com/cars/technology/a26695/diy-engine-rebuild-saves-57000/ Quote Link to comment

Canadian510 Posted June 1, 2017 Report Share Posted June 1, 2017 Something a little different I was working on today. How about a 47 litre V12 making 1500hp and 3500 ft-lbs of torque, with transmission and cooling system weighs about 7 tons though haha 1 Quote Link to comment

125 CSL Posted June 2, 2017 Report Share Posted June 2, 2017 Judd makes a work of art, museum quality. Then again it would be a shame just to look at it. 1 Quote Link to comment
